"Sorry sweetie, daddy took forever to leave for work. Now just lay back and mommy will get you out of bed and ready for school." Laura said in a rushed, husky voice, and the line itself was a perfectly ordinary thing for a mother to say to her thirteen-year-old son at the start of a school day.
But that was as far as 'normalcy' went. A mother uttering that phrase wouldn't be buck naked and almost panting with desire as she straddled an equally naked colt, the boy lying back with his arms folded behind his head and already sporting an erection that put his aforementioned father to shame. Adam just relaxed while his mother positioned her noticeably wet slit above him, the mare's hands shaking with a desperate need as they grasped her son's prodigious appendage just below the flared tip.
"That's okay mom, but if you don't hurry up I'm going to miss the bus and you'll have to drive me to school..." the boy said, smiling a little as he watched his mother spread her lips with one hand as she guided his tip to the now exposed pink of her love-tunnel.
"Th-that's okay sweetie. Mommy doesn't mind driving you and, well, the rest..." the mare mumbled, her brain slowing down to a crawl as all of her attention went to the bulbous flare now wedged between her lips, the tip leaking her son's pre into her already soaked muff.
The colt smiled a little as his mother slowly lowered herself onto his throbbing length, knowing what 'the rest' entailed - being stuck in a car with the voluptuous mare and knowing his load was still leaking from her well-bred slit as she drove him to school would always have him hard again, despite the fact he'd just blown a load inside her less than an half an hour ago. After all, he'd wind up pumping out about a dozen during a regular day, and his mom was considerate enough not to send him to school with such an embarrassing tent in his pants, so the mare would quickly and quietly park and suck her son off, swallowing every drop before waving him goodbye and wishing him a nice day.
The mare that had given him birth moaned out loud as she slid further down his steely length, her face taking on that glazed, lusty look she'd wear while riding him to completion. He couldn't help but admire the buxom mare, noting that her recent pregnancy was quite kind to her. His mother's generous hips had flared out just a bit further and they looked amazing as she swiveled them slightly, getting his cock to rub all the right places as it invaded her depths. And her always impressive cleavage was equally enhanced, two firm but heavy breasts swaying tantalizingly from her chest, the usually pink nipples now a few shades darker and still puffy from being nursed by the little 'brother' she'd given him.
His mom was lucky in that respect that she could easily pass the child off as her husbands. True, it didn't have any of the black stallion's colors, but neither did their first son. Laura's coat was a creamy gold while Adam was a coppery bay, but both of them and the two-month-old foal shared a white starburst on their foreheads as well as pale manes and tails. The colt knew the non-equine women carrying his children would be in an awkward situation, but he didn't let that bother him. After all, not one of them regretted getting bred by him and were happy to carry his foals, provided he still gave them some attention, which reminded him.
"Mom, I'm going to be back a little late. Mrs. Wilkerson asked me to help her out around the house, so I'm going straight over after school." He told his mother, the mare quickly plummeting down the last few inches of his cock with a grunt, a transparently possessive gesture as she tried to mask her jealousy.
"Oh, but sweetie, don't you think you're... overdoing it a little? After all I need... I mean you need your rest. You're a - Aaah! - growing boy..." the mare managed to say, gasping as the colt flexed the cock now buried as deep inside her as any male had been, the shaft seeming to grow twice as thick for a few seconds before relaxing a little.
"Now mom, we've talked about you getting jealous, remember? Or do I need to ground you again?" he said, and he knew how much the threat had startled the buxom mare by the way her pussy had just clenched up around him.
"Aaah, no sweetie, sorry! Mommy will be good just - ungh! - just don't leave her empty again..." Laure babbled, grinding her splayed lips against his crotch at the thought of getting 'grounded' again.
The last time she complained about the number of other women her little boy was visiting he got so upset with her petty jealousy that he didn't touch her for five days! She thought she would go crazy during that time, trying to get by with just her husband, the black stallion so surprised by his wife's sudden appetite that he'd jokingly asked if she was trying to kill him. When her boy had finally decided she'd had learned her lesson and gave her what she desperately needed she came fiercely the moment he'd bottomed out inside her, and couldn't even count how many orgasms had followed by the time her young stud filled her with his love.
And she really did learn her lesson, realizing how wicked she was for keeping the other women in town from experiencing such happiness and how kind and generous her son was for sharing his gift with all those unsatisfied females. She knew how lucky she was to be living with him and have the privilege of waking him up like this every morning, but every now and again she got these petty ideas of keeping him for herself.
Eager to prove to her boy she was better than that, she began to lift herself off that glorious shaft, her lips clinging to the mottled length now glistening with their combined juices. She gave an eager little whimper when the thick ridge of her boy's medial ring popped out of her and managed to lift herself a few inches further, half her son's cock still buried firmly inside her silky sex. She gave her hips a bit of a wiggle as she slid down, moaning whorishily as that mammoth spire reclaimed her marehood.
Even after all this time her sex hadn't fully adapted to having the colt's extraordinary length inside it, her son's shaft always seeming to stretch her just a tad too far, a hint of pain in the sea of mind-bending pleasure. She was taking it slow for now, knowing she needed to adjust a little or she'd be sore (but still deliriously happy) later. Placing her hands on her son's firm chest she began to ride his cock at a steady but sensible pace, her lush rear rising and falling as the motherly mare gasped and moaned with every throb and twitch of the cock trapped in her eager sex.
Adam rewarded his mother efforts with a warm smile of satisfaction, knowing by now the effect it had on females. The more time slipped by the harder it was to remember when he viewed women just like any other adult, or when he viewed adults as authority figures, as a matter of fact. He'd always had an eye for pretty girls and beautiful women, but before puberty he didn't have any instinct, any drive to push him further than a fond glance. And before he started developing, young ladies and grown women both had always commented on what a handsome little boy he was but never felt the need to go further with him than a peck on the cheek or a hug.
When he was eleven he noticed he'd started to grow - his shoulders got a bit wider, his muscles more defined, and his pants were feeling tighter and tighter. Women were no longer referring to him as a handsome little boy, and when they looked at him now they often seemed to bite their lip or rub their thighs together. And when hugging him they didn't seem to mind if his hands slipped a bit lower than their back, and when his growing colthood would stir against a woman's leg as she held his head to her breast, he could always hear their hearts start to thud in their chests.
It was a little after his twelfth birthday that things really changed. He'd walked out of the shower without his towel on since he'd gotten hard as a rock while washing himself again and it was impossible to hide his already mammoth shaft whenever it got like this. His mother had spotted him as he came out, his tail and mane still wet, steam still rising from his damp fur, the moist air perfectly carrying the fresh and heady scent of the young stud's musk as his cock bobbed and leaked in front of the mare.
After taking a moment to recover, his mom had quickly ushered him to his room, and told him she needed to tell him about the 'birds and the bees'. To this day he still didn't learn anything about neither birds nor bees, but that afternoon his mother had taught him, by example, what a boob-job was, and once his dad was asleep she'd snuck into his room and explained what a virginity was and how important it was to give it to someone who loves you more than anything in the whole world.
Having his mother wrap her arms and legs around him, mewling with joy as he pumped away between her shapely thighs changed Adam's view drastically. His mother had always been loving, but now she was always so eager to please that it reminded the colt of when he was too little to reach the freezer and he'd act as nice as possible around mommy to get ice-cream. Now it seemed he had the cream the older mare was eager for, and it filled the young colt with a masculine confidence that the other females around him soon recognized, the sort of confidence that many had, at least subconsciously, been waiting for him to show.
Adam had been the only twelve-year-old who never jerked off, and to this day he didn't know how. There was never a reason for him to learn, because whenever he wanted to feel a hand on his shaft (or a mouth, breasts, pussy or pucker, for that matter) all he had to do was decide on a female. It had been hard to see adults as authority fingers after that. How could he when he could make women do whatever he wanted, and whenever he did they would scream out loud how he was more of a man than their husband or boyfriend?
Exhibit A - his mother praising him with what little breath she had as she rode his lap, her back now straight and her heavy breasts bouncing wildly on her chest as she drove her hips up and down on his shaft. Deciding mommy had learned her lesson he reached out and put his hands on those ripe teats, barely able to palm the lusty mare's mammaries as her nipples stiffened under his touch.
"There, see how much nicer this is when you don't get jealous?" he asked, kneading the heavy globes in his hands as the mare fucking herself on his cock shuddered form his touch.
"Oh God yes!" the mare panted, thrusting her chest out even further as she bounced wildly on her young stud's cock, feeling the steely length mash against her cervix every time her lips smacked against his crotch.
"And after all, Gloria's your friend. You wouldn't want her doing any hard work this late in her pregnancy?" he added, omitting that her mother's friend was technically carrying her grandchild.
"No sweetie, you're - umpf! - such a good boy for wanting to help!" the mare said, although she was pretty sure what sort of 'work' Gloria needed her son for.
She was one of the early ones to catch on to what's put the spring in the step of several ladies on their block. The she-bear had noticed the way the young colt had filled out (and where) as well as the strange way Laura was acting around him. And one day when they were over at their house for a barbecue, Gloria had asked the colt to help her out in the kitchen and made her move. Adam smiled at the memory of the quick but vigorous rutting he gave the curvy bear gal as she leaned on the kitchen counter, as well as the way she'd walked out of it looking more flushed than her husband who was working the grill. Still, that little romp was nothing compared to what he did with her next time they met. Her hubby had been clueless enough to leave on a fishing trip when his wife had gone into heat, and she didn't hesitate to call Adam over and beg him to put a foal in her. As it happened, he planted two.
Turning his attention back to the mare riding him with every ounce of his strength, he decided since mommy was being a good girl he might as well help her out a little. He was, after all, a very loving son and a little work-out would help him start the day right. He kept fondling the bouncing mare's ripe teats, noting that his palms were getting wet despite the fact that they'd only recently been suckled dry by the little foal now sleeping happily across the hall.
The colt carefully timed himself, waiting for the moaning mare to reach her apex as she slid as far as she could off his mammoth member. Just as she began to drive her hips back down, Adam bucked up and sent his own flying up to meet them, the loud smack of the two equine bodies hitting each other loud enough to be heard over Laura's ecstatic squeal.
The mare put her hands on her thighs to steady herself as she held her hips half-way along her son's length, doing her best to just keep herself up as her boy began to pound away at her needy slit, the smacks getting wetter and wetter as her body wholeheartedly welcomed the assault, even as the colt's bed protested. She bit her lower lip to muffle any further cries, not wanting to wake up the foal she'd just gotten to sleep and not trusting herself not to scream with sheer delight as her son fucked her like nobody ever had.
Time seemed to stretch out as her marehood was rutted and Laura was a mess, going from one climax to another in such rapid succession that it seemed like just one massive orgasm that threatened to overwhelm her lust-fogged mind. She could feel sweat soaking into her fur as the painful smacks of her son's crotch slamming against her sex became just a throbbing heat spreading through her loins.
She had her final orgasm when she felt her son's flared tip mushroom up, spreading her almost painfully as the little tip in the middle kissed her cervix, preparing to pump her womb full of the colt's seed. As she slammed her hips down and ground her winking slit against the base of her son's cock, her only regret was that she wasn't in heat.
She was biting her lip so hard she almost drew blood and still only barely managed to muffle a feral-sounding whinny as the first pulse traveled up her little boy's cock, the thick goo surging against the barrier of her womb before rushing in and filling her with that glorious sensation of liquid heat. The first gush was followed by another, and then another until the blissful mare lost track, her sex clenching and milking around her stud's shaft, eager for every single drop.
She could have stayed like that forever, especially since she knew Adam could often go several times without his shaft getting soft, but one look at the clock on his nightstand told her they'd already taken too long. As a sense of motherly responsibility rushed back, she almost leapt up from the slowly softening cock, the flared head popping out of her and leaving a thin strand of milky-white cum connecting the two lovers.
*******
As it turned out, mom had to drive him to school yet again, and Adam would have been sure she was making him miss the bus on purpose just so that she could 'take care of his situation' in the car if the mare wasn't so obviously skittish about being caught with her son's cock down her throat. After she'd pulled her sex off his cock earlier the mare actually had to spend a few minutes rubbing some feeling back into her legs before she was sure she could drive.
After she'd parked, she wasted no time bending over and sticking her head in her son's lap, engulfing the already hard shaft in her mouth and carefully letting the thing slide down her gullet. He had to admit she looked adorable with her muzzle bobbing in his lap while her ears twitched nervously, scanning to make sure nobody got near enough to the car to see what she was doing, and to whom.
She'd gotten good at deep-throating him, and after a few minutes of sucking his shaft and fondling his heavy sack he gave her what he knew she wanted. The mare had become an expert at taking his load down her throat, making sure to swallow every single drop and leave his cock clean after she pulled off. The first few weeks she'd always wind up sputtering whenever she sucked him off, and would apologize to him even as she made sure she licked every errant drop up.
Adam was running quite late for his first class despite his mother's efforts, but still didn't pick up the pace. First period was history with Ms. Finn and he knew she wouldn't mind him being late as long as he showed up. Just as he figured, the mousette almost squeaked out when she heard the door open and she saw him come in.
"Aah, Adam! I was worried you weren't going to come... I mean in time... to class! J-just have a seat and we'll pick up where we left off... with the lesson!" Danielle squeaked out, her tail shooting up and her thighs beginning to rub together the moment she saw the colt in the door.
Now all she had to do was keep it together a little while longer. All right Danni, you can do this. You're a professional! Just hold on until the bell rings. She thought to herself as the sound of her heart pounding filled her big round ears. She'd been worried that the colt wouldn't show up and the sight of him took her from frazzled to horny in the span of a heartbeat. She could feel her little slit tingle and moisten in anticipation, her cheeks becoming flushed and the nipples on her perky breasts...
...are on full display!
The white mousette's face went from pink to rosy as she realized the little tips were clearly outlined against the creamy blouse she was wearing. The material wasn't all that sheer, but the diminutive femme had eschewed any underwear, not wanting to waste precious seconds taking it off. Knowing that covering her chest up would only draw more attention to her, she decided to just try and tough it out.
"Now, as I was saying, the success of the Roman legion was due in no small part to the uniformity and standardization of the equipment each soldier issued. At first, the principal spear of a legionnaire was the hasta which was a... t-thrusting spear..." the mousette went on, trying desperately not to rub her shapely thighs together in front of her students. The desk! Of course! I'll just nonchalantly try and make my way to safety...
"In time that gave way to the pillum which was a bigger, heavier version of the weapon..." the mouse continued, straining to speak as she subtly edged closer to her desk. Reaching the edge she realized it wasn't high enough to hide her crotch and that she'd have to sit down at some point. "I-it had a longer, thicker shaft that tapered down, becoming somewhat slimmer just below the fla- I mean head! Spearhead!" she squeaked out as the class stared at her, and only then did she realize she'd been subtly grinding her crotch against the corner of her desk. Her face now as red as a beat, the mousette quickly plopped down on her chair, thankful that her desk had a modesty panel. That thought seemed to move her hand, the fingers drifting lower and lower as she struggled to finish the lesson.
"The difference in size and weight meant this spear could be hurled with such f-force that it could penetrate the... uh... uhm..." the mouse trailed off for a few seconds before the bell mercifully sounded.
"OK-that's-it-for-today-no-homework-just-review-your-notes-see-you-next-week-bye! Adam-I-need-you-for-a-few-minutes!" the mousette rattled out in one breath, jumping up with enough force to send her chair spinning back into the wall behind her. Once the last of the students were out she quickly locked the door and closed the blinds before hiking her skirt up around her slim waist and jumping up to sit on Adam's desk.
"You think we'll have time for the whole thing, Ms. Finn? I only have a short break before my next class." Adam said, drinking in the sight of the flustered mousette sitting on his school-desk with her legs spread, her steamy little cunny on display as she fumbled with the buttons of her blouse.
"You're excused. The principal wants to see you..." the panting teacher husked as she fought to undo her top with shaky fingers. She'd only managed the first few buttons, enough for the blouse to open a little and give Adam a glimpse of her snowy cleavage. Danielle didn't have a huge set but the perky mounds looked amazing on her tiny body, the mousette standing a little shorter than the colt now eyeing her.
"The principal? Any Idea why?" he asked. The stern-looking lioness was one of the few female faculty members who hadn't expressed any interest in him so far.
"Ah- I don't know, but don't worry. If you're in trouble I'll cover for you. We'll cover for you!" the frustrated femme panted out, hinting at the numerous teachers that had a very strong reason to keep the colt around and out of trouble. Danielle gave an angry squeak and gave up fumbling at the stubborn buttons, tearing her blouse open and sending them flying across the room.
"Was that a good idea?" the colt asked, smiling as he feasted his eyes on the sight of his teachers heaving, and now quite bare bosom.
"I've got a spare in my desk." She said, remembering the last time she got fed up with her buttons and had to staple her blouse closed!
Having said that, she laid herself down on top of his desk, spreading her legs wide and raising them up in a very unsubtle invitation. Adam didn't really want to make her wait but he couldn't help enjoying the sight of how adorable the flustered mousette looked as he undid his pants and began to fish his imposing shaft out. The meaty member was already out of its sheath, and as the colt gave it a few strokes it soon firmed up under his touch.
He smiled at the sight of Ms. Finn's abdominal muscles visibly twitching with every pump of his now erect cock, the rodent femme's eyes as wide as saucers behind her glasses as they focused on the object of her desire. He let his cock drop down, the mousette squeaking when the girthy shaft slapped against her trim belly as Adam drew his hips back, that heavy head trailing lower and lower. Even as the blunt tip slid across her pubic mound, the mousette's hands flew to her desperate sex, spreading her lips as wide as she could to help the colt enter her.
As he wedged his head between her lips, Adam reached out with the hand he'd been stroking himself with and brought two finger's to the mousette's mouth. His teacher eagerly parted her lips and let the digits slide past them, immediately suckling on them and licking the taste of his cock from them. That wasn't really the reason for the gesture, as she'll be able to taste a lot more pretty soon, but the mousette liked to be rutted quite vigorously, and could take it amazingly well considering her petite frame.
The one thing she couldn't do was take him silently and since cries of "Fuck me raw you glorious stud!" weren't very appropriate for the school, he needed to keep that pretty little muzzle shut. Despite that the mousette managed to squeal out through her little button nose as he pushed in, plunging his head and several inches of his shaft into the writhing rodent. The mousette was bucking her hips, her perky ass bouncing up and down on the desktop as she urged Adam to give her more, her trim tummy already showing the faint bulge of his cock as it filled her up.
When he finally bottomed out inside that tight snatch the colt felt his teacher's slender legs wrap around him, the mousette's eyes glazed as she moaned around his fingers. With her holding him back he couldn't pull out very far, but he didn't mind since his the rodent femme's clenching love-tunnel was stimulating enough, and he knew the elfin female got off on being stuffed to the brim and could easily cum just by having the equine appendage poke and prod inside her.
He began to rut her in fast, short thrusts, the desk scraping against the floor as it was nudged and bounced with every buck of Adam's hips, the mousette he was pumping into making similar squeaks for the same reason. It took only a few seconds of this for him to feel that already tight sex grip down on him as his teacher's pussy gushed happily around his length, his next few thrusts pumping out her nectar and smearing it all over his crotch. Since he was still not close he kept fucking her right through her orgasm and into another, his tail swishing proudly behind him as Danielle's ropey appendage wrapped around his waist.
After another minute she seemed to snap out of it a little, extending her arms out and making grasping motions in the air. Adam knew what she wanted and acquiesced by leaning down over her, pulling his hand from her mouth and replacing it with his lips as he kissed the flushed mousette. Her arms soon wrapped tight around his strong neck and once she was secure Adam pulled up and away from the desk.
Danielle squeaked into their kiss as she slid even further onto the young stud's shaft, her weight driving her down until her lips were pressed against the colt's sheath. She took a moment to savor the sensation of the thick base of his cock stretching her like nothing ever had before, the living length throbbing and leaking inside her eager sex.
After that brief interlude, she broke the kiss and gave Adam a quick nod before burying her little muzzle in his neck. The smell of his fur filled her nostrils as he began to buck his hips, bouncing her up and down on his cock a few times. She kept her lips pressed into his coat to keep herself quiet, shuddering when she felt his hands first palm and then firmly grip her perky little ass, the colt holding her securely as he began to rut her in earnest. 
The thrusts were shallow, every single one was battering away painfully at her cervix, but the mousette was too far gone to tell pain from pleasure at this point. After all, if she spent the night with an ice-pack between her legs and took a few aspirin in the morning she should be able to walk almost normally tomorrow. She didn't worry about getting home since she always seemed to float after her encounters with Adam.
When she felt the colt's flare mushroom up she almost wailed. Too soon! She wasn't ready to cum again just yet, but she was close! In the midst of her little panic attack she felt one of Adam's hands shift, fingers sliding along her parted cheeks until one slipped under her tail, pressing against her little rosebud and then...
The mousette's buck teeth bit into her lower lip as the colt's finger slipped into her tight little butt just as the first blast of his cum flooded her womb. Her limbs tightened around the colt's body as she came around that erupting shaft, her stud moaning into her ear even as he continued to tease her little pucker.
Once he was done filling her up, Adam sat the mousette back on the desk, his teacher reluctantly releasing him as she plopped down on the hard surface. She mewled as the semi-hard length was pulled from her well-fucked sex, remembering to press her palms against her loose slit the moment Adam's flare slipped out.
"Ahh - t- top drawer, left side..." the panting female said, managing to catch the big roll of kitchen towels the boy tossed her before walking out of the classroom.
*******
"You wanted to see me Ms. Stephens?" the colt asked politely after stepping into the principal's office. 
"Ah, Adam Palmer. Do come in and close the door behind you." The lioness seated behind a large desk instructed, sparing him a quick glance over her slim reading spectacles.
Closing the door the colt was surprised to find this side of it leather-wrapped and soundproofed, but he knew the school building was fairly old. What he didn't know was that principals down the line had protected their office from various remodels, and the old-fashioned wood-paneled room served as a fitting domain for the feline now presiding in it, sitting behind the large desk like a queen would on her throne.
The lioness folded her glasses and set them down as she stood up, walking around her desk with smooth, graceful steps as she took in the sight of the young colt. He really didn't seem all that special. True, he was a strikingly handsome young boy, with his still lanky body showing signs of a magnificent stallion to come, and his beguiling face seemed playfully innocent despite the impish gleam in his brown eyes. Certainly enough to stir a girl's interest, but a woman's?
As she took in the sight of him she noticed that young Adam was quite brazenly doing the same to her. A boy his age, not to mention his situation, would have had a hard time trying not to stare at the tawny feline's figure, but most would try to steal an occasional glance. The colt's eyes roamed her body as if they had every right to. Traveling up her shapely legs, concealed from the knee up by a clingy black skirt that failed to hide the swell of the feline's thighs and hips, up to the point where the dark fabric gave way to a white blouse that fit snugly around her waist and billowed quite noticeably in the chest.
"Adam, I've called you in here to discuss the peculiar attitude some of the faculty have towards you. Many female teachers seem quite eager to excuse your tardiness, or entirely missed classes, as well as deadlines for various papers and projects. When asked why, they all claim you are a model student, but become somewhat tongue-tied when asked for details..." the lioness finished, cocking one elegant eyebrow in challenge.
"What can I say - women just seem to like me..." the colt replied, giving the imposing feline an impudently charming smile.
"Hmm, so you think of yourself as a bit of a charmer. And I can see how you managed to do so well, given the nature of your 'audience' - mares, cows, does, mice..." the lioness counted, seeming less than impressed "I can see why all of them would find you appealing - handsome but non-threatening. That is the defining trait of prey species - the desire to seek that which is tranquil and harmless, and to avoid danger. A handsome little boy with a quick smile could do well with women like that..." she said, and Adam realized that although she had her suspicions, she had no idea just how far he'd gotten.
"Predators, however, are a different matter. We embrace danger and seek out confrontation because there our will and strength are truly put to the test. A show of strength isn't enough to make us balk or shy away. In fact, our reaction is generally quite the opposite." She finished, leaning down a little and looking straight into the colt's eyes.
A feline gaze was always an intense thing, and the proud lioness knew full well how potent hers was. She couldn't count how many times she'd sat at a bar, while various strapping stallions, bulls and stags - virile males at their peak - drank in the sight of her as they mustered up the courage to approach. Then they would stride boldly forward, nonchalantly buy her a drink and give her their best look. 
But a few seconds of peering into those slitted amber orbs would be enough to reduce the confident male to a stammering mess, like a child caught doing something they shouldn't have. Yet the colt's easy smile didn't falter as he met and held her gaze.
"You have very pretty eyes." He finally said, and the lioness couldn't help but smile, not at the compliment, but the sheer brazen bravado of the young equine.
"And you have more charm then sense. But like I said, you won't find me that easy to charm. I'll do what those timid females couldn't and make a proper young man out of you. For starters, take out whatever you've stuffed down your pants to create that ridiculous bulge." She said, crossing her arms under her prodigious chest, confident of her victory.
"Whatever you say, Ms. Stephens..." Adam replied in an acquiescing tone but his grin never faltered as he unzipped his pants and pulled out the thing stuffed down them. It was quite a sight to see those pretty eyes go wide as the lioness' composure faltered for a second as she looked with disbelief at what the young colt had produced.
"Well you are... gifted, I'll give you that. I suppose I can see how some of the more timid females would be overcome by something like..."
"Well, thanks for the compliment Ms. Stephens, but it's really more of a grower than a shower." The colt said, interrupting the lioness mid-sentence.
"Is it really?" the feline almost purred out, one eyebrow cocked and the eye beneath it glittering as she recognized the challenge in the colt's voice.
An idea quickly took shape in her head, and while it was improper, to say the least, she was an educator at heart, and believed this brash young colt needed to be taught a lesson. Namely, that he couldn't control just any female, no matter how well-endowed he was. She smiled as she looked down at him, taking a few very short steps to close the distance between them, and with every step undoing one button from the top of her blouse. She had to admire the young equine's composure as he kept his cool even as he ogled her now exposed cleavage, the creamy breasts pushed up high on her chest by a black-lace bra, a sight that made grown men go slack-jawed and wide-eyed.
The lioness' knees gracefully folded as she knelt in front of Adam, her mesmerizing eyes now level with his as she put one paw on his growing shaft, the warm length giving a little surge as her hand wrapped around it. She began to stroke the equine spire with a masterful technique, squeezing her palm gently with every stroke up the veiny length. 
Although the colt didn't immediately melt into her touch, she could tell he was enjoying himself by the way his nostrils were flaring as well as the way his shaft rose and firmed up under her touch. The feline's own delicate nose began to twitch as the young equine's cock began to leak, the lioness soon taking in deep breaths, each one rich with the young stallion's musk. His scent was fresh and sweet, carrying all the vigor of youth, but underneath that was the unmistakable fragrance of a virile male, something that her body responded to on instinct.
Deciding to up the ante she smiled wide, showing off her beautiful yet terrifying teeth before opening her muzzle and sliding it down the colt's now rigid shaft. The taste of him was even better than the smell, and the lioness couldn't stop a deep purr as her lips wrapped themselves around the equine appendage. She looked up, pointing those intense amber orbs at the colt and hoping to see him overwhelmed, but the boy still seemed to be wearing that devil-may-care smile he'd been sporting since he walked into her office.
 Not to be outdone, the lioness slid further down his shaft, suckling as she did and caressing the veiny length with her nimble tongue. She was surprised to discover that even with opening her throat to the young stud's cock she could still only barely reach his medial ring. Unwilling to admit defeat, she began to stroke the equine flesh that lay exposed, her hand milking more and more of the colt's juices that how muzzle eagerly drank up, her own sex seeming to moisten against the black silk of her panties with every drop that she swallowed.
"I appreciate the effort Ms. Stephens, but if that's all you can take it's not going to be enough..." Adam said, and he could see that the remark hit the lioness straight in her pride. The feline slid her muzzle off the colt's shaft slowly, sucking on it as she did and dragging her tongue along the underside so that it flicked across the flared head once it had left her lips.
"Is that so?" she asked, looking Adam dead in the eyes as she licked his juices off her muzzle "It would seem the other teachers have been spoiling you. Very well, if I can't please you, let's see if you can do better..." she said, her otherwise cool voice becoming husky, seductive but at the same time betraying her own need.
She got up and did a quick but effective striptease for the young equine. She faced him as she unbuttoned and then shrugged off her blouse, her bare shoulders high and squared, perfectly framing her chest. The bra was next as the feline unclasped it and let it fall to the floor, smiling all the while. She took very good care of her body and was pleased to note even the colt's cock gave a twitch as he saw her lush breasts barely sagged even without support, hanging just low enough to go from round to tantalizingly tear-shaped. She decided to tease him by denying him the sight of her rear, facing him as she undid her skirt and slid it and her panties off in one smooth motion. As she bent over to do so, her ripe mounds swayed from her chest just in front of the colt's face, and she was glad to see his nostrils widening as he took in the fragrance of her bosom.
"Could you get on all fours?" the colt asked in the same voice one might ask to borrow a pencil "Only, it's not like we have a lot of options considering how much bigger you are than me..." he added as the lioness stared down at him.
The predatory feline just smiled at his brazen request, determined to stay in control. She twirled around and once her back was turned to the colt sank to her knees. She then proceeded to plant her palms on the carped and for the finale she arched her back, thrusting her sculpted rear out at the cocky colt. She flicked her tail up both to reveal her moistening slit to the young equine, and to send her scent wafting in his direction.
Adam didn't balk at the obvious challenge, hunching over that perfect heart-shaped ass as he brought his dripping tip to the feline's inviting slit. He pried her lips open with one hand while the other wedged his flare inside her, this principal letting out appreciative sounds as she felt the heat of his cock at the entrance to her sex.
Once his tip was securely inside her, he placed a hand on each tawny cheek, gripping the firm globes securely as he gave a thrust that speared almost all of his length inside the unsuspecting feline. The lioness' head shot up, an almost feral yowl leaving her throat as her sex was forced to suddenly stretch around the invading, but nevertheless welcome shaft. She felt her silken walls clenching around the colt, registering every contour of the throbbing maleness conquering her depths.
Another buck and she felt the colt's trim body smack against her rear, her insides now stuffed to capacity by the length that should have been swinging between a full-grown stallion's legs. Her only consolation was that it worked both ways - if she was feeling this stretched out, then her love-tunnel must feel devilishly tight around the colt's cock, and the young equine would be forced to slow down to stop himself from coming after only a thrust or two.
"Wow, Ms. Stephens, you really are up-tight!" the boy buried inside her said, his voice lusty but unnervingly steady. The lioness didn't trust her own voice to remain steady enough to reply. "But don't worry. If there's anything I know, it's how to get a pussy to loosen up."
Before the proud feline could protest at his language, she felt his hands on the pins keeping her hair in a thick, tight bun. The colt deftly removed them and let her caramel-colored locks cascade down her naked back.
"You have very pretty hair, you should wear it down more often..." the boy remarked innocently even as he flexed his cock, making the monstrous pole swell inside the impaled lioness for a brief but delicious second.
"Now, what was it you said about predators?" she heard him ask as his hand closed firmly around the base of her tail "Oh yeah - you embrace confrontation as a test of willpower." he added and the feline bit her lip as she felt his grip tighten just as his shaft slid out of her.
It seemed to take forever for the colt to pull everything but the flared head of his cock out of the lioness's slick sex, the proud feline muffling her moans but remaining powerless to stop a rumbling purr building up deep inside her. When the young equine suddenly reversed his momentum and shoved the whole thing back in, pulling her rear back by her tail, the purr changed into a growl, but even that didn't deter Adam.
The colt just tightened her grip on her tail with one hand and her hip with the other as he began to piston his cock in and out of that tight feline muff. The lioness was finding it harder and harder to maintain composure under the assault, the discomfort of having such a girthy cock buried between her splayed lips giving way to pleasure as her tunnel wrapped itself lovingly around the throbbing length. She was no longer biting her lip, her mouth hanging open as she panted, fighting for breath rather than dignity.
No man had ever dared treat her this way, most of them considering themselves lucky to be under the gorgeous feline and willing to let her lead. What's more, the lioness had never considered she might enjoy submitting like this, and still couldn't believe she was doing it now, and for a mere child! She wasn't surprised to find she was starting to push back to meet his thrusts, the colt no longer even needing to pull her back by her tail and choosing instead to let his hand's roam.
Adam felt Ms. Stephens shudder under his touch as his fingers trailed along her sides, gliding across that perfect waist and then along either side of her chest before gliding lower, following the contour of the firm breasts jumping back and forth with every buck of his hips. He palmed the heavy mounds, the feline's stiff nipples slipping between his fingers and he gave each luscious globe a good hard squeeze, pinching the sensitive nubs between his digits as he did.
The cock-dazed lioness could feel her pussy clench up as her breasts were expertly groped, the colt's rough treatment of her sensitive teats only serving to fan the flames already burning without control in her loins. She felt him speed up, only pulling out far enough to make that thick medial ring slip in and out of her needy sex, the sensation of that ridge driving the feline wild as it rubbed her lips from each direction. She felt her orgasm mounting as the young equine expertly manipulated her body and knew it was going to be a big one, that this kid was going to make her loose her composure the way no man ever did. But she found she no longer cared, her purring now interrupted only by needy, desperate mewls as her body cried out for blissful release. And then the colt stopped.
"W-Wha... why..." the once proud feline panted, unable to form the question. Fortunately, there was no mistaking the tone in her voice.
"Do you want me to make you come, Ms. Stephens?" the colt behind her asked, keeping so agonizingly still that the lioness found herself sliding back and forth on his cock, a futile attempt to get herself off.
"Yes!" she cried out. The colt could surely see how desperate he'd made her. What kind of game was he playing?
"Well, it just that I was taught both at home and school that if you really want something, you should ask nicely..." he said innocently and the lioness couldn't believe her ears. Fine then, if the price for her climax would be the last shred of her dignity, she was willing to pay.
"P-please..." she husked.
"What was that?"
"Please fuck me! Rut me hard and leave me dripping your seed, just please let me come!" the lioness cried out, not believing the words rolling of her tongue.
But they did seem to be the magic words, and the lioness was almost pushed over by her colt's next thrust, yowling in delight and pain as that blunt tip rammed itself against her cervix. She began to purr, still occasionally mumbling 'please' as she braced herself for the hard fucking she'd begged the colt for.
Adam's hips were a blur as he let go of all restraint, his young chest pumping like a bellows as he began to breed the eager feline for all she was worth. Despite his calm demeanor, the colt was close, the thrill of a new conquest always serving to spice things up. And since his principal had so politely asked for a hard rutting he didn't have the heart to disappoint her.
As she felt the colt's flare begin to grow inside her, stretching her already snug pussy painfully wide, the lioness was surprised to feel the colt's fingers in her thick mane a second before he gave a sharp tug, pulling the yowling feline into a kneeling position. His other arm wrapped possessively around her chest, squeezing her breasts tight as he held her close, and when she felt his blunt teeth bite her between her neck and shoulder she finally let go.
Adam could feel his principal writhing in his grasp, her pussy coming alive as it caressed the equine length, seeming to beg for his seed. It was a wish Adam soon granted, growling lustily into the lioness' neck as he claimed her womb for the first time, thick, heavy ribbons of equine spunk shooting into the twitching feline's depths.
"Well Ms. Stephens, I have to say I feel like I've won this confrontation..." he spoke softly into the panting female's ear "...but since you're a proud predator I know you'll want to face me again for a contest of will and strength. That's okay. I'm willing to give you as many rematches as you want." He finished, pulling his still firm shaft slowly out of the whimpering lioness and lowering her front to the floor. He took a moment to wipe his glistening cock clean on her furry rump before sticking it back into his pants and walking out of the office, leaving the once-proud feline with her ass in the air, fresh equine spunk dripping from her well-fucked slit as she drooled mindlessly on the carpet.
*******
"Ooh, that was a strong one! Did you feel it?" the reclining she-bear asked the colt busily nursing on one massive breast, her young lover responding with a short nod as he brushed a hand over her swollen belly.
The expecting mother in Gloria was so touched by the gesture that she didn't even mind the hand had left her moist folds unattended, knowing she'd get to enjoy more than just the young stud's fingers soon enough. And the relief he was giving her chest was an entirely new delight as the colt played with the nipple he'd already suckled dry while working busily on the she-bear's other teat. Gloria's little foals were due in about two weeks, but she'd started producing a little early and didn't even realize how swollen her breasts had become until Adam groped them and sent two milky sprays shooting across the room.
The young colt was enjoying both the foreplay, as well as the luscious bear's milk. She was by no means the first woman who'd asked him to taste-test his future offspring's first food, but lying beside the gravid ursine he had to admit he was impressed. Gloria's fluffy rack had been a sight to behold even before her pregnancy, and with the growing those massive mammaries had done he doubted she'll have any trouble feeding the soon to be born twins.
The big fluffy momma-bear was stroking his mane with one paw while the other was busy somewhat lower but was in a way also stroking his head. While Gloria's pregnancy did little to reduce her appetite, it had made her a lot cuddlier. About eight months ago she would already be screaming out for Adam to rut her harder even as she pushed the colt's muzzle between those ripe mounds, making the young equine unable to reply in any way other than with an increase in speed and force as he pummeled away between the larger female's thick thighs.
One he felt her flow slow down to a trickle he gave the little nub one last flick of his tongue as he pulled his lips off the spent teat and took a moment to admire his handiwork. The brown she-bear was now visibly flushed, laying on her back with that massive chest heaving, both pillowy breasts sporting shiny mocha-colored nipples in a sea of downy nut-brown fur. The momma-bear caught him eating her up with his eyes and gave him a warm smile before turning onto her side and away from him.
"C'mon sweetie, spoon up!" she cooed as she raised one leg up and gave a few shakes of her stubby tail.
Not wanting to keep the she-bear waiting any longer, Adam stretched out behind her and hooked an arm under her knee, keeping Gloria's thighs open as he poked and prodded with his twitching shaft. As he pressed his body close to the plush ursine, he savored the sensation of her fur both against his own coat, as well as the sensitive head of his questing member. Gloria's fur was dense but incredibly soft, and he knew from her smell that she made sure to shower before he came over, making her coat even fluffier. He also knew that as their encounter went on the fruit smell of her shampoo would give way to the female's natural scent, a perfume both warm and unabashedly wild. 
It took a few more careful nudges but once the feathery feeling of the she-bear's fur gave way to the moist silkiness of her slit, Adam knew he'd found the right spot. Gloria moaned out lovingly as his tip spread her lips before slipping in, the rest of his shaft sinking into the eager female in one smooth stroke.
This position didn't allow the colt to bottom out in the motherly ursine, but he didn't really mind, especially since it meant he could really give her a good rutting without worrying about hurting their foals. He held himself like that for a while, swiveling his hips so that the twitching shaft would prod around the she-bear's velvety walls, the gravid female cooing appreciatively as her young lover skillfully sought out her sensitive spots.
"C'mon sweetie, don't make the mother of your foals beg! Give it to me the way only you can..." Gloria finished in a pleading tone dripping with her arousal, and the colt sheathed inside her wasn't about to disappoint.
He drew out as far as he could out of the needy momma-bear, his glistening length leaving her folds with a deliciously wet sound before he gave a buck of his hips and buried himself once again in her warm, slick sex. The fluffy female gave a pleased sounding little 'oof!', her bulging belly bouncing a little but since she didn't protest, the colt began to rut her in earnest.
Gloria's eyes became lidded, her gaze lost in the distance as she focused on the sensation of the young stud pounding into her, his thick equine cock filling her like no male ever had, every ridge and contour on it seeming like they were made to rub against her love-tunnel in just the right way. She tried looking down, but her swollen belly denied her a glimpse of what she knew was a magnificent shaft sliding smoothly past her plump lips, the mottled length already shiny with their juices.
She slid own paw lower, past the impressive baby-bump she was sporting until her palm glided across her lower belly and finally found what she was seeking. She had no intention of playing with herself, knowing Adam was more than capable of getting her off, and instead pressed her soft paw-pads against the steely length pounding in and out of her muff. 
Now that is a male! The bear thought as she admired the sensation of the colt's shaft as it slid against the palm of her hand, the length rock hard flesh beneath a layer of smooth, silky skin, now drenched in the lovers' juices. She decided she was going to lick him clean again once he was done, her tongue flicking over her lips in expectation as her mind already conjured up the image of the equine spire dripping in the colt's cream, the rich smell of his seed filing her nostrils as her muzzle inched closer.
That same glorious cock that had planted two lovely foals inside her the first time she'd let him in while she was in heat. Something her husband had failed to do time and time again. He would spend only a few minutes whitin her, but would roll over sweating and panting like he'd just run a marathon. And then when his meager offering would fail to take, he had the nerve to suggest that she go to a clinic to check if she was the problem.
Well, she'd give him a little surprise in a few weeks' time. And she'll make sure the pathetic excuse for a male thanked her for the opportunity to play father to her foals, or she'll tell everyone that she found a man to give her something he couldn't.
Adam's next thrust drove all thoughts of the lack-luster bear from her head, and she wondered if her lover had noticed her mind was elsewhere. Eager to make up for it, she let out a long, low moan, her voice shaking with each thrust of her stud's hips. He slid an arm around her, his hand coming to rest on her taught belly, a thoughtful and possessive gesture of a rutting male admiring his handiwork.
She put one paw on his, holding his hand in place as he sped up, his cock barely sliding out of her as it sawed in and out at lightning speed, the force of it enough to make the large she-bear's body bounce as her young lover redoubled his efforts. Gloria felt her walls wrap around the invading length, a cry of sheer delight leaving her throat as her climax washed over her, leaving her shuddering in the young stallion's embrace. 
She was sure she would soon feel the tell-tale flaring of her colt's tip as he emptied those heavy equine orbs inside her, but she was proven wrong when Adam fucked her straight through her orgasm into another before ramming himself as deep as he could and giving her what she so desperately needed.
*******
"Ah Adam, thank you so much for coming!" Jane hissed happily at the sight of the colt as he stepped into her office, her hood fanning with excitement.
"No problem Nurse Reid. So, you mentioned you wanted me for some sort of study?" the colt asked, curious about the young cobra's intentions, and more.
He hadn't had the opportunity to spend any quality time with Ms. Reid since she'd only been around for about a month. Even though everyone called her 'nurse', the truth was that she was actually a post-grad who ended up doing her residency here after their previous school nurse had to go on a rather unexpected maternity leave. Well, unexpected by everyone other than Adam, who'd always enjoyed playing doctor with the now expecting zebra.
The snake's eyes didn't miss the way the seemingly innocent young boy's eyes were taking in the sight of her, and she felt that her hunch was about to pay off. The previous school nurse had given her the run-down on the student body, but when mentioning a certain colt she'd blush and lose her train of thought. And then there was the way the female staff acted around the colt - affectionate rather than authoritative, seeming eager for even a bit of innocent physical contact. That had made the serpent wonder what they were like when out of sight, and why.
"Yes, although if you agree, this will have to stay our little secret. Nobody can know you helped me and you'll be in my paper as just an anonymous donor. Think you can do that Adam?" she asked.
"Sure thing, Nurse Reid. I'm quite good at keeping a woman's secrets." The colt quipped in an innocent tone of a young boy eager to be of help, but Jane couldn't help but wonder at the implication behind his statement.
"Well, I'm glad to hear, and actually the way you are with women is sort of what I'm interested in. Now I'll just need to ask you a few questions. One - are you producing sperm?" she said without batting an eye, but was surprised when the boy nodded without so much as a blush. "Well, that's good. And two - are you sexually active?" she asked, getting another nod.
"Well, that's good too. Now I'm not sure of you ever heard of oxytocin - it's a neurotransmitter and many have started calling it 'the love hormone' because of the effect it has on the brain, especially when it comes to bonding. It seems females are particularly responsive, and it traces of it have been discovered in seminal fluid, so I'm sure you're guessing why you in particular are of interest to me." The nurse said, her tone becoming a bit sly and conspiratorial. "Now, since you are so good at keeping feminine secrets, I'm not going to ask you for details, but what I do need from you is..." she trailed off and held up a specimen jar as a finish to her question.
"Well okay, but you'll have to help me with it." The colt replied, still unfazed by the serpent's request.
"What do you mean?" the nurse asked, a little confused and noting that the young colt seemed to be rather shamelessly taking in the sight of her.
"Well, I've never cum on my own." the young equine said, the statement more of a boast than an admission.
So that was his deal? the cobra thought with a wry grin. Well, she wasn't all that surprised. Ever since she came to the school she had felt the eyes of pubescent boys being drawn to her form, and not just because she was the only snake in the school. Jane had a body that was very slinky even by a serpent's standards - slim hips that nevertheless looked eye-catching because of her waspishly thin waist, but a surprisingly generous chest, especially considering her lean figure.
As a consequence, she couldn't find a nurse's uniform that really fit, settling in the end for one that fit snug against her middle even if it meant she couldn't button it all the way up. The overall effect the white top had was almost like that of a corset, the fabric clinging to her slim mid-riff while pushing her breasts up.
No wonder the colt standing shamelessly in front of her was trying to take advantage. But if the price for his cooperation was a simple hand-job, the snake didn't mind paying it. After all, the sheer thrill of having her stroke his length with her cleavage on display would make him pop in a minute, at most!
"All right then, Adam. Just drop your pants and we'll get started." The snake said, turning around to retrieve a packet of lube. After she'd turned back and saw the young equine proudly standing with his length already dropping from his sheath, the snake changed her mind and took the whole box. Looks like I'm not the only snake in the school after all!
It took nine packets to fully coat the colt's member, and Jane had wondered if it would ever stop growing. She was certain the young stud would wind up setting a new world record once he was all grown up, and began to see why even adult women seemed to flock to the young boy. Hell, she'd be tempted herself, if she wasn't a dedicated professional! 
Still, even with her professional resolve she couldn't help her tongue from flicking out as one long-fingered hand wrapped (barely!) around the twitching member, her hood fanning a little in surprise. The equine shaft was alive in her grip as she stroked one hand deftly along its astounding length. 
"Uh, Nurse Reid, you're doing fine but I don't think one hand will be enough..." the colt said, openly taking in the sight of the snake's cleavage as she bent over to stroke his shaft. 
Smiling a little at the boy's brazen attitude, Jane knelt in front of him, coming face to face with both the young stallion and his member. She brought her other hand up, first using it to palpate the heavy-looking pouch hanging bellow the twitching rod, letting her scaly palm slide up along the thick base before she closed her fingers around it. She began to work the colt's girth with both hands, pumping in unison as her tongue flicked out, her sharp sense of smell and taste telling her she was getting a reaction from the young male, but that he was nowhere near close.
"I don't think this is working, Nurse Reid. I'm sorry to ask but do you think you could sort of put it between your breasts?" he asked, and Jane's hood fanned out in shock at his request. "It's just that it often does the trick..." the boy finished, his expression and tone seemingly innocent despite the indecent nature of his proposal.
Jane found his attitude curiously charming, and answered his grin with one of her own as she began to undo the buttons on her top. After all, the snake had a kinky side as well, one which was revealed at the same time her bare breasts were, the cobra long ago having decided that the tight uniform gave her plenty of support.
The colt in front of her was certainly enjoying the sight of her bared chest, the perfectly formed mounds covered in tiny beige scales in the front, giving way to an elaborate diamond pattern done in browns and blacks on her sides and back. She hefted the ripe globes and let them fall back down, the reptilian breasts bouncing a few times as her nipples stiffened visibly.
But even as the boy drank in the sight of her his expression didn't falter, despite the fact that the snake knew this little show tended to have grown males drooling, especially when she wore her uniform to bed. She tore open another pack of lube and let it slowly drizzle all over her impressive rack, some of the thick goo running down between the glorious globes and disappearing from sight. She proceeded to rub the gel into her mounds, and once she was done her little scales glittered and shone like thousands of tiny semi-precious stones, polished until each one gleamed.
She let Adam's shaft slip between her shiny teats, noting with some surprise that she could barely get them to touch as she squeezed them around the equine cock. Once she had him in her cleavage, the snake began to lift both her breasts and her torso, rising and falling in a practiced, undulating motion as she slid herself up and down the young stud's fleshy spire.
This got a reaction from the young equine, and Jane knew from his gasp that she was his first snake. Males tended to get nervous about having hard scales pressed against their pride and joy, but as long as she was generous with the lube, they all changed their mind as the thousands of tiny pebble-like plates slid teasingly across the sensitive flesh of their members, each one teasing all those sensitive nerve endings along their meaty lengths. She continued sliding her whip-like body up and down the young colt's cock, letting the thick member glide along the underside of her long, sinuous neck every time she reached its thick base.
"Uhm, Nurse Reid, I hate to bother you, but..." Adam trailed off suggestively, and Jane let out an exasperated hiss as she nevertheless got the message. This boy was really going to make her earn her sample!
When she next reached the tip of the colt's shaft she flicked her forked tongue over the blunt flare, taking in the surprisingly pleasant taste of the young equine before opening her mouth wide and sliding it down. And down. And down!
"Wow Nurse Reid, I'm impressed! Even Mrs. Rhoades couldn't take my whole cock in one go!" the colt happily exclaimed as he looked down to meet the cobra's eyes. It took Jane a few seconds to put a face to the familiar name. Ah yes, the mother of Will Rhoades - the giraffe boy...
She appreciated the peculiar compliment, but couldn't really take credit for it, since snakes were unbeatable when it came to deep throating. Anyone taking a cock like Adam's down their gullet had a clear advantage when their ancestors had swallowed their prey whole, and it came handy to have only two teeth in your mouth, and those being easily retractable.
All those factors meant that even though her long, slender neck was visibly bulging from being pulled over the colt's twitching cock she had no trouble taking him, proven by the fact that her scaly nose was even now pressed against his sheath, the forked tongue darting from beneath the girthy length to flick against that heavy looking sack.
Jane had to admit she was having fun 'collecting' the colt's sample, and was even enjoying the taste of him in her mouth. Her hands went around the colt and settled on his firm young cheeks, holding him in place as the cobra began to slide her mouth off his member, twisting her neck sensuously as she did. Her hood was fully fanned now, betraying her arousal as surely as her tail did, the tip slowly sliding up one leg until it reached her moist lips. After all, there was no reason for the boy to have all the fun.
The snake kept sliding her head up and down the colt's mottled length, amazed at how long the young stallion was lasting under her expert assault. Despite how easily it was stretching around his mammoth member, she knew her throat would be achingly tight, gripping the shaft lovingly every time she swallowed around the throbbing girth. Deciding to up the ante a little further, she reluctantly took one hand off his firm cheek and used it to palm his pouch. As the weight of the two equine orbs settled into her hand, she felt the shaft lodged down her throat give a little spurt, telling her she had the right idea.
She began to fondle the boy shamelessly, trying to get that heavy sack to unburden itself even as her tail slipped into her own sex, the scaled tip's poking and prodding only serving to spur her on. When the colt's pouch tightened up and left her hand, she knew she was about to get what she'd been working so hard for, and the snake pulled her mouth all the way down on the boy's cock as she eagerly stroked the heavy orbs now drawn up against his body.
She felt the head flare deep down her serpentine neck, and had no doubt that the trumpet-like tip was visibly bulging as the equine above her groaned. She felt his balls twitch and tense in her gentle grasp, felt the thick tube running beneath his cock swell with the first rush of equine seed, yet she was still caught by surprise as a blast of the colt's spunk shot directly down her gullet. From her vantage point she could see his abdomen flexing, feeling the same rhythmic movements through the palm still groping one of the young stud's ass-cheeks, a powerful biological mechanism pumping what seemed like and endless supply of stud milk into the stunned serpent.
As she pulled her mouth half-way off Adam's spurting length, the snake felt a sharp discomfort in her stomach and quickly worked to undo the buttons holding her top closed over her trim tummy. Jane had ben certain the boy was spent or close enough when she let his tip slip out of her mouth, staring in disbelief at the size of his flare before the shaft erupted again, sending thick ropes of white across the scales covering her face.
Adam shot several more ribbons over Jane's face, and the cobra's head and hood were dripping with the young stud's spunk before she remembered to actually get some in the specimen jar. Fortunately, even the boy's last few dribbles were enough to fill the container half full as the snake milked the softening length of every precious drop.
As she replaced the lid on the jar she looked down at herself and couldn't believe her eyes. Another trait snakes had inherited from their feral ancestors was that their waists were always thin and their bellies flat, but tended to show a little bulge even when their owner enjoyed a big meal. Jane's stomach was visibly rounded, to the point that she looked like she was about to lay eggs. No wonder her uniform had felt so tight once they boy started cumming down her throat! Well, she was about to get a first-hand experience on the effects of oxytocin on a female's brain chemistry, considering how much the colt had left in her.
"Well, I got what I need..." Jane said, even though she knew it wasn't strictly true. She also reminded herself to pick up a six-pack of batteries on the way home. "...and I'll be sure to call you in if I need any more." She finished, her mind already racing as it tried to think of a scenario that would require her to collect a sample more intimately.

"Mr. Phillips, can I talk to you about the grade I got on my test?" Adam asked the serious-looking stag seated behind his desk.
"You can. I'm not sure what good you think it will do." The deer responded somewhat coldly.
"It's just that I'm not sure if I deserve an F..."
"On the contrary, that's exactly what you deserve..." the stag replied promptly, his voice taking on a lecturing tone "I know there are some teachers in this school who believe in just giving out good grades, but in my class, your grade is a reflection of the effort you put in, and as far as I could tell, you didn't put in any."
"I know, but I have a lot of responsibilities outside of school and it's kinda hard for me to find the time to..."
"You don't fine time for what's important, you make time. Do you understand?"
"Fine, teach, I'll make sure I put more effort in..." the colt acquiesced. Well, to his credit, he did try to solve things by just talking them out.

"There we go pet. Do you like that?" the voice was sweet yet with a hint of menace in it, and just the sound of it made Warren's cock twitch as he lay on his back, limbs tied to each of the bed's four posts and a blind-fold hiding the sight of his wife.
He could see the doe in his mind's eye, a black corset hugging her already slim waist, giving her a jaw-dropping hourglass figure and making her creamy breasts stand out even more. She would be standing somewhere above him, that long, graceful neck craning as she admired her handiwork and planed her next step. The bound stag wasn't struggling, but the tension his wife was building in their little game was having an effect, his chest heaving as he took deep breaths, heart racing with excitement.
"I hear my pet has been very bad, and needs to be taught a lesson. Are you going to take your punishment like a good boy?" the doe asked, her tone betraying her own arousal, although she was keeping it together a lot better than her husband.
"Y-yes, mistress." The stag almost panted out, licking his lips with anticipation. There was something in Sophie's voice that told him his wife was going to get quite creative tonight.
"There's a good pet. Now take a good sniff..." she said and Warren could feel two wet finger's pressing against his nose. He did as he was told, the fragrance of his wife's sex flooding his brain, the always enticing scent ten times more powerful now that his sight was denied to him. Even when she took the fingers away, the honey she'd smeared on his nose-pad still filled every breath he took with the heady aroma of a doe in heat, to the point that the bound cervine felt like he was drunk on it.
"Well, I think you're ready. Come on in, sweetie!" his wife called out, and at first Warren was confused, thinking she was talking to him. He realized he was wrong when the door opened and he heard hooved footsteps on the bedroom carpet.
"Wha-who..." the panting stag tried to ask but his wife silenced him by pressing those still damp fingers against his muzzle.
"I didn't say you could speak without being spoken to, did I? Now just open that muzzle and stick your tongue out like a good pet, I don't want you embarrassing me in front of company." She finished, and the stag's mind reeled.
                There really was someone else in the room? But as shocked as he was, he was also quite well trained by now, and his lips had parted without him realizing it, tongue lolling out as he waited in complete darkness while the third person seemed to approach the bed. Something was placed against his tongue and the prone male felt a jolt run up his spine at the sudden sensation of true helplessness. Whatever was being rubbed against his lips felt silky, completely bare of fur. 
He felt the heat coming from the smooth skin, tried to sniff it out but all he took in was the lingering scent his wife had smeared over his nose. He wondered at first if it was another woman's sex being rubbed against his muzzle, but his tongue could find no slit, no parting. It might have been a nipple, but the thing was too firm, and seeming to get harder. He suddenly tugged against the ropes securing his arms as he realized he was licking another male's length.
"All right, he's had a taste, now let's let him see what a real man looks like..."
"Sure thing, Mrs. Phillips!" a voice quipped back in an eager-to-help tone, too high in pitch to belong to the male rubbing himself over the bound stag's tongue, yet somehow familiar.
The blindfold was removed, and while the cervine squinted against even the dim lights of the bedroom, his frazzled brain managed to link the familiar voice to the face, the same one now smiling as it looked down at him.
"Hi, Mr. Phillips. Boy, you and your wife sure seem to have a fun marriage, huh?" Adam asked even as he rubbed the underside of his stiffening length over his teacher's muzzle.
                "Sophie, what the..." the stag cried out, but quickly felt silent when his wife took a very firm hold of his sack, squeezing it hard enough to stop the protesting male mid-sentence.
                "I'm your mistress until I untie you, remember?" the doe said firmly, only releasing him once he nodded. "As for Adam, he got in touch with me to talk about the way you've been treating him, and after listening to him as well as a number of other teachers, all of whom, I might add, had only good things to say about him, I decided to teach you a little lesson. And since you've been such a bully to this young man, I felt he needed a chance to get even."
                "Sorry, Mr. Phillips, but I did try to work it out with you first, remember?" the colt asked, his sheepish smile out of place as he looked down at the almost panicking stag.
                "Warren, just because you liked spending your youth with your head buried in a book, doesn't mean everyone else has to. And since you don't seem to understand what sort of needs a boy like Adam has, I thought I'd show you..." the doe finished, and Warren could feel the mattress shift as her wife got into bed with him. Looking down past the colt's now fully erect shaft he could just barely see his wife's heart-shaped rear, her tail raised to display the treasures hidden beneath it.
                The sight certainly wasn't helping him think as his lust-fogged mind raced. The stag and his wife didn't even have a safe word for these little games. She'd told him she'd rather not have one, since she never really did things that could cause serious pain or harm, and said it meant a lot to her for him to trust her enough to let him be his mistress and put himself fully in his hands. Since she'd given him a literally doe-eyed look when she said it, Warren had agreed without hesitation, and had never regretted it until now.
                "Come on, Adam, you've played with my pet long enough." She said in a honeyed tone, and warren could see her wriggling that perfect rump, her pink slit noticeably moist. "You just show me what a young stud you are, and I'm sure he'll do his best to make himself useful, won't you dear?"
"Y-yes, mistress..." the stunned stag replied on reflex, still unable to believe what was happening.
But, seeing is believing, and as his wife scooted back and her young guest moved into a kneeling position with one knee on either side of his head, he realized he'd have quite a good view. But despite seeing the colt's shaft, Warren still couldn't believe his size! As a stag he didn't have a problem with length, but the girth of the equine appendage was unbelievable, easily three times as thick as his own, not counting the flare. He wondered briefly if it would even fit inside his wife, but as he saw the doe use the fingers of one hand to spread her lips wide and expose her velvety tunnel to the young equine, he realized she intended to try.
Adam pulled the eager doe back a little so that her now dripping slit was directly above her husband's muzzle as he pressed his head against her parted petals. Mrs. Phillips cooed out, her tail flagging further and her back arching as she invited him to claim her, her pink lips dimpling slightly before the blunt head popped in and they closed snug around his shaft. 
The colt's ears had been perked up, eager to catch the sound the doe made as he entered her. Despite being an unabashed womanizer, Adam was a sentimental soul deep down and remembered vividly and fondly every sound a female had made when first taking him inside her - the gasps, squeaks, moans, mewls, whimpers, a few roars here and there and on one occasion an honest to goodness trumpeting from an honest to goodness elephantess. The sound the doe made was an almost melodic gasp, as sure a sign of eagerness as her tunnel milking around his shaft, eager for more.
"Aaah, g-good boy! Keep going, show me what a real male feels like!" the doe moaned out in a shaky voice, her tail twitching and her eyes rolling back as the colt holding her rear fed more and more of his young cock into her eager sex.
Warren couldn't believe his wife was taking the young stallion's shaft so enthusiastically, her delicate lips looking painfully stretched, splayed as they were around the narrowest part of the colt's member. And he had the beast seat in the house to watch as the young equine sank deeper into the all too willing doe, her abdominal muscles twitching even as they bulged out slightly, distended from the girthy rod being pushed into her.
The stag felt his own cock twitch at the sight, not surprised he'd never lost his erection during all this. He was too well conditioned by his up till now faithful wife to respond a certain way to being tied up and ordered around, so much so that it had never occurred to him to close his eyes, or to protest further. There seemed to be no end to the mottled length forcing its way past Sophie's quivering lips and the stag found himself mesmerized by the equine spire, eyes tracing every ridge and contour of its surface as his wife moaned and gasped, appreciating the texture of the colt's member in an altogether different way.
When the colt's sack came in to view, the deer blushed as he had to lower his muzzle to prevent the low-hanging pouch from bumping into it. Until then, Warren had never felt his own package was inadequate, but he knew full well that his sizable white-furred sack couldn't measure up to what was swinging between the young equine's legs. The two heavy orbs hanging in front of his eyes looked massive, the hairless black skin containing them making the twin bulges look all the more prominent.
"Ahh, fuck!" the doe cried out as the thick base of Adam's cock was pushed into her already straining sex.
"You okay, Mrs. Phillips?" Adam asked, scratching the base of the doe's tail as her velvety walls molded themselves around his shaft.
"Y-yes honey, just... give me a second to adjust. I've never had anything this big inside me..." she panted out, and Warren felt his cheeks burning at her request.
His wife generally didn't need a lot of time to get in the mood, so to speak, and didn't need any when she was in heat. If this had been a normal night for the two, the doe would have slid onto his cock in one smooth stroke and proceeded to ride him almost violently straight away. Either that, or she'd be bent over, pulling on his leash and urging him to hump harder, warning him against even thinking of getting off before he made her cum. Somehow he doubted she'd be admonishing the colt the same way.
"Ok, sweetie, you can start..." the doe husked, her long ears twitching in anticipation.
"Are you sure it doesn't hurt?"
"A little. But even when you hurt me it feels good..." the doe replied, her voice pleading for her young stud to rut her.
The young colt wasted no time pulling his massive shaft out of the female's clinging sex, the entire length glistening with the two lovers' juices, droplets of it dripping down on Warren's face as all but the flared tip left his wife's stretched slit. The stag clenched his jaw at this latest humiliation, actually struggling against his bonds until the colt above him reversed direction and sheathed himself once again in what was, at least until now, definitely his doe.
His wife's lusty cries took the fight out of the bound male, the doe almost screaming out with delight as she was once again impaled on her young lover's length. Sophie wasn't very vocal during sex, or so Warren had believed. Whenever he would lay with her all he could get were low moans, coos, and an every now and again she'd either tell him what a good little pet he was, or give him instructions on how to get her off.
But as the stallion began to slide himself in and out her wet sex, she was squealing and moaning like she wanted all the world to hear her get fucked by her new stud, her voice almost but not quite drowning out the wet sound of the young equine's cock as it pistoned in and out of her, and the smack of his hips against Sophie's shapely ass.
A few thrusts later and she cried out even louder, and the stag's ears flicked back in utter humiliation as he recognized that sound, although not its intensity. He wasn't surprised when he saw his wife's stuffed cunny gush around the cock crammed inside it, her juices splattering over his muzzle as the colt's shaft pumped them out of the climaxing female's twitching pussy. Warren would usually be a panting mess by the time he'd managed to get the doe off, but the young stud above him had managed it with about ten thrusts.
"See Mr. Philips, I'm putting in effort, just like we talked about..." the young equine cheerfully said, although it really didn't sound like he was. He wasn't winded or out of breath, in sharp contrast to the doe he was still busily rutting who was alternating between panting and begging her stud for more.
Warren gasped out when he felt his twitching cock slide between two soft, fluffy mounds, a familiar and welcome sensation. He thought his wife had decided to at least let him tit-fuck her, but he soon realized he was wrong. She didn't even seem to notice his shaft in her cleavage, and he'd only managed to get it in there because she'd lowered her chest in order to take the colt's shaft more easily.
As unintentional as it was, the stimulation was enough to cloud the stag's mind which had been more than a little hazy since his wife's honey had splattered all over his muzzle. There was a new scent mixed in with the perfume of a doe in heat, and before the stag realized what he was doing his tongue had slipped out to lick at both his wife's lips and the shaft sliding in and out of them.
"Wow, Mrs. Phillips, you were right, he is getting into it!" the colt exclaimed, completely unfazed by the sensation of the prone stag's tongue cleaning up the mess the two of them were making.
"Tol- ah! -told you he was well trained. And if he - umpf! - ever wants to fill in when you aren't around, he'll be a good little pet and make himself useful!" the doe said, coming down from one orgasm and already sounding like she was working herself up for the next one.
As shaky and breathy as her voice was, there was no mistaking her tone, so Warren made sure to redouble his effort, running his tongue over both his wife's slit and the invading equine shaft. He realized that despite the age difference, the colt was a male he couldn't compete with, so if he was going to salvage his marriage, he was ready to take any roll offered to him.
He kept up his licking, trying to ignore the colt's heavy sack as it bumped repeatedly into his muzzle. With his face in the way, the young stallion couldn't slide himself all the way into the eager doe, but judging by the sounds his wife was making he didn't need to. After a few minutes of brutal thrusting he no longer felt the equine sack hitting his muzzle, and after he opened his eyes he realized why.
The heavy orbs were pulled up tight against the stallion's crotch, looking no less prominent as his wife cried out and begged the colt to breed her, no doubt feeling the equine head flare inside her, signaling her stud's orgasm. As he watched those massive balls twitch as they unloaded their burden into the fertile doe he knew for certain that Sophie wasn't using birth control with the colt, and all Warren could do was hope that the child would resemble his wife. That way he could at least pretend it was his.
He saw the underside of the colt's cock flex over and over, swelling with each surge of potent equine seed as it flowed along that mighty shaft, not a drop of it leaking out past his wife's splayed lips, the flared head of the stud's shaft forcing her to take the entire load deep inside her. He saw Sophie shudder and heard her bleat out like a feral doe as she came from nothing but the sensation of the young stud's load being pumped deep inside her. The young stallion had given her than she could take, a fact made evident when the colt pulled out, a splash of his cum landing on the bound stag's face as the flared tip popped out of his wife's well-bred cunny, leaving her lips slightly agape.
"Well I guess you were right, Mr. Phillips, putting in effort does get you a passing grade. But I don't want to be just a D student..." the colt gloated, putting emphasis on the 'D' as he grabbed his still hard shaft just below the shrinking flare. "What do you think teach, should I go for the A?" he asked, bringing the slick tip up until it was pressing under his wife's tail.
Well now you've pushed your luck too far the stag thought, certain that his wife was about to throw the brash youngster out of bed. Even though she was quite eager to play with her pet's tail-hole, his wife was dead-set against anal, and the young equine was about to realize that he...
"Yes, please! Stick that glorious shaft under my tail and fuck my tight little ass senseless!" Sophie cried out, her whorish plea interrupting the stunned stag's train of thought.
The young stud wasted no time, pressing the slick flare firmly against the straining doe's opening with one hand while holding her shapely ass in place with the other. Warren could see the action quite clearly, but even if he didn't have such a good view he'd have known the moment the stallion slipped in by the high-pitched whine leaving the doe's throat. His eyes went wide at the sight of her beautiful pink pucker, barely visible as it stretched out against the colt's cum-clicked shaft, the tender ring of muscle pulsing eagerly around the impaling flesh.
"Hold on, sweetie, let me - ungh! - let me get used to you. Warren, be a good - ah!- pet and clean me up..." the doe panted, and before he knew it the stag's tongue was slipping easily past her messy still-parted lips, his mind reeling from the taste of both a doe in heat and a stallion's cum.
The taste of the two seemed to get the stag drunk as he dipped his tongue in over and over, all the while watching his wife's ass twitch around the equine appendage stuck firmly between her cheeks. After a while she asked him to fill her, and the bound male watched the mottled length slowly but surely sink into that fluffy white behind, claiming the virginity that the doe wasn't willing to give to the man she married.
As his cock sunk further up his Wife's ass, Warren could feel it pushing some of the colt's cream out of the doe's well-bred sex, the velvety tunnel seeming to get tighter as her rear-end was stuffed. As the young stallion sheathed more of his massive shaft into the all too willing doe, the stag felt her tits press against his length as she lowered her chest against his crotch. At this point he knew she wasn't doing it for his sake, rather that she was face down and ass up in an effort to get her young lover as deep inside her quivering rump as she could.
Once he was balls deep in the doe, Adam began to rut her rear, slowly at first but speeding up as the panting doe begged for more. Warren could only lick and watch as a cock that dwarfed his own made the usually dominant doe writhe and plead, her stretched pucker now shiny with the cum from the colt's gleaming length.
The stag tried to compete, to stick his tongue further inside the doe in the hopes that he could at least pretend it was his tongue that was making her moan, but his wife would drive the point home by calling out the colt's name every time she got her breath back. He was smacking into her hard enough to push her chest back and forth over Warren's cock, and soon enough the stag found himself grunting with his muzzle deep in his wife's messy slit as he came into her white-furred cleavage.
"You okay down there, Mr. Phillips?" the colt inquired, not even breathing hard even though he was now pounding the moaning doe's ass at a savage pace.
"The - Aahhh!- the buck just made a mess on my chest... Don't worry, I'll make him clean it up later just - ungh! - finish up... Make me take every drop like you made me take every inch!" the doe begged, leaving her husband with little doubt as to what would be expected of him once the stud was done.
As it happened his wife came twice before the colt did, each gush of her honey flushing the excess equine cum onto Warren's busy tongue, although the stag knew that a lot more was safely sealed away in the doe's fertile womb. Not a drop escaped the cervine female's twitching pucker, but once the young stallion's massive flare was pulled out, a splash of spunk followed, splattering all over the stag's face before the doe above him managed to squeeze her ass tight, obviously eager to keep her lover's gift inside her as long as she could.
Warren was then forced to promise he would stop 'harassing' Adam, and the defeated stag knew it was no use arguing. From then on the young equine handed in blank test sheets that his teacher then filled out, and was a straight-A student. That didn't stop him from fucking the stag's wife, but Warren was allowed to be present and of some use when he did and fill in for him as best as he was able whenever the colt couldn't make the time...
*******
"Adam!"
The squeal of delight was the last thing the colt heard before his face was buried between two magnificent breasts and the skimpy pink top struggling to contain them.
"Omigosh, I've missed you sooOOOooo much!" a bubbly voice gushed above him and the young stallion felt what he knew was a delicate muzzle burry itself in his mane as the vixen hugging him took a long, eager sniff. "Mmmmhh, just as good as I remember, and it's not even the good part! God, it just feels like forever since I last saw you..." the vixen kept cooing as she rocked the trapped equine back and forth.
"It's been about two weeks, Steph..." the colt mumbled from inside his squishy prison. Not that he minded being smothered by the cheerleader's perfect teats, but the bubbly vixen did tend to get a little overexcited. Thankfully, he knew how to calm her down.
"Uhm, Stephanie..." an altogether more timid voice sounded from behind the enamored vixen, prompting her to release her prize and spin around to face the speaker.
"Omigosh, I'm so sorry, where are my manners! Adam, remember how you asked me to bring over a friend next time I came over to babysit? Well this is Nancy!" she announced, putting her arm around a cute ferret girl blushing under the black band covering her eyes.
"Uh, hi..." Nancy said, a bit surprised at the way the young colt in front of her was looking her over. But if half the things Stephanie had told her about him were true...
"Nancy is a bit shy, but we've been besties for as long as we can remember, and there's no one I'd rather share you with than Nancy!" the vixen beamed, squeezing the blushing girl against her "Now, the two of us have been playing around for years now, and Nancy's never been with a boy. She's not even sure if she likes them, but I told her if she's only gonna try one guy's cock in her life, it should be yours!"
"Stephanie!" the ferret girl squeaked, her face turning red as a beat at her friend's candor.
"Don't worry sweetie, I'll go first so you don't get scared. Besides, I called first dibs, remember?" the vixen asked, already struggling to get out of her skimpy outfit. "Ughhh, stupid clothes! I was going to do a whole strip-tease for you sweetie, but now that I'm here I just gotta have you in me as soon as - umpf!- possible!" she exclaimed, managing to get her top over her head to reveal two massive but perfectly firm globes bouncing on her chest as she began to attack her skirt. Once she was done with that, she hooked a thumb on each side of her thong and practically pealed the panties off her shapely rear.
"Ta-da!" she said as she turned her back to the two, bending over as she lifted her big, fluffy tail up to reveal a pink gem glittering between her cheeks.
"Steph! You mean you walked with me all this way with that inside you!?" the ferret squeaked out, one hand flying to cover her mouth while the other toyed with the hem of her skirt. She wound up coming here in her school uniform - pleated skirt and a white blouse - because Stephanie didn't think anything in her closet was sexy enough, and reasoned that a schoolgirl uniform could always pass for sexy.
"Duh! And it's a big one to, so my stud doesn't have to waste time getting me ready. Waiting's frustrating enough when I'm not in heat..." the vixen pouted as she began to work the plug out of her perfect ass.
"Well Stephanie, you could always leave it in..." the colt suggested, his tone of voice the perfect temperature to melt girls' hearts.
"Ooooh, I know sweetie, and I'm definitely gonna let you plant the cutest little orange-furred foal in me one of these days..." she cooed, giving a cute little grunt as the plug finally poppet out of her well-lubed ass. Stephanie's eyes went wide at the sight of the metal monster that had until now been buried under her friends tail. Would she even be able to feel the colt after that!? "It's just that I want to hold on to this body for at least a little while longer..." she finished, turning around to face her young stud before running her hands up her curvaceous form, starting from her flared hips, up her tiny, trim waist and finishing by cupping those mouth-watering mounds covered in the softest creamy-white fur.
Stephanie was blessed with a body that's usually only possible if you have the number of a top-notch plastic surgeon and a six-figure budget. Just looking at those perfect curves, deliciously firm under the vixen's downy fur, was enough for Adam to forgive her for not letting her knock her up. He'd just have to 'settle' for that bouncy, heart-shaped ass, already shiny and twitching in anticipation.
"Ugh, why are you two still wearing clothes? Am I the only one being serious around here?" The vixen groaned, signaling her frustration by swishing her big fluffy tail and prompting the two to strip down.
Nancy was slowly undoing the buttons on her shirt, getting far enough to reveal a white cotton bra hugging her perky breasts, the plain undergarment looking rather cute on the shy female. Adam had taken his shirt and shorts off with a speed that revealed his experience, and the moment she saw his shaft snaking out of that plump sheath the ferret's fingers sped up, urged on by a deep feminine instinct.
"Ooh, not hard yet? Well, I know how we can fix that!" the vixen chirped happily before turning her back to the two before stretching her legs until her rear was level with Adam's crotch. She turned around and gave the two a little wink before lowering her front, hands stretched out in front of her until her splayed fingers were touching the floor. With a final flourish, the vixen arched her back and threw her big orange tail up and out of the way, revealing the creamy band of fur running between her cheeks, an already dripping slit and a very inviting pucker nestled within it.
"And that is why everybody wants to fuck a cheerleader!" she exclaimed happily, easily holding the strenuous looking pose, her prefect teats hanging down until the tips of her nipples were just barely brushing the floor. "Okay now Nancy just help him in already, I'm going crazy over here!" she said, flexing her ass a few times and making those perfect cheeks bounce a little.
As Adam walked up to the eager vixen Nancy did as she was told, gripping the colt's shaft and unconsciously licking her lips as the tower of equine flesh flexed under her touch. Looking at the stallions cock, she realized the huge plug Stephanie had been wearing would just barely prepare her for what was about to slide into that well-lubed behind.
Still holding Adam just below his blunt head, she used her other hand to spread one of the vixen's orange cheeks, her friend cooing as that shiny pink rosebud gaped slightly. She guided the stallion's tip to the twitching hole, and wasn't sure what to do next as she pressed the flare against the vixen's slick pucker.
Fortunately the colt knew, putting one hand on Steph's cheek to steady her while grabbing her tail with the other. Nancy gasped at the same time her friend moaned, the young stud wasting no time as he pulled the vixen back at the same time he thrust forward, sinking in the flared tip and several inches of his twitching member in the blink of an eye.
"OooohmyGOSH!" the vixen cried out, tongue dropping from her delicate muzzle as her eyes rolled back, a look of sheer ecstasy on her face as Adam continued to sheathe himself inside the vulpine's slick ass.
"S-Stephanie, are you okay?" the ferret stammered as she watched the colt's maleness disappear into the vixen's ass, her pucker now a thin pink ring around the girthy shaft.
"Uhg fuck yes! C'mon Adam, rut my rump off!" the vixen begged, and Adam just smiled as he shoved the rest of his cock until his base was stretching the lusty vixen to her very limit and her wet pussy was rubbing against his smooth sack.
Nancy just stared wide-eyed as what had at first looked like a very cute kid began to fuck her friend's brains out with the equipment and vigor she'd never even seen in porn! She couldn't believe the sounds, or the words coming from the usually bubbly vixen's muzzle, her face burning as the only intelligible things coming from Stephanie's mouth were pleas so lewd they'd make a whore blush.
But there was no way of denying how much she seemed to enjoy the painful-looking rutting. Looking beneath those bouncing cheeks spread eagerly around the impaling cock she could see, and soon enough smell the honey leaking from that familiar vulpine slit, the lips seeming to gush a little very time the colt's now shiny sack smacked into them.
She was wondering what she could actually do here, not wanting to stand and stare like some nerdy wall-flower. An idea entered her head and the ferret blushed as she bent over her friend's heart-shaped ass, one hand lovingly grasping each cheek before her fingers dug in the soft fur and spread them as wide as she could.
Stephanie cried out as she came from the sensation of her friend lovingly mauling her tush even as Adam bred her ass for all it was worth. Her pleasure only intensified as her snug back door began to clench up around the invading shaft, caressing and milking his length and showing her lover just how eager she was to feel him cum inside her.
It had been a slow day for Adam, so he picked up his pace, his own hips a blur as he jackhammered the still climaxing vixen. He could tell she was straining to hold the pose by now, the muscles in her slender arms taught as each buck of his hips threatened to push her over, her toned legs trembling from holding the half-split.
Stephanie's eyes shot open wide when she felt that wonderful flare bloom inside her, stretching her out as much as she could take before her young lover hilted himself in one brutal thrust, pulling her tail back to keep her impaled on his twitching shaft as the first wave of his cum erupted inside her. Her eyes rolled back in her head, tongue lolling out as she panted, each breath timed to the pulses of colt-cum shooting into her well-bred rump.
"N-Ah!-Nancy, get the plug ready..." Stephanie managed to say, her speech sounding slurred and drunken as her tongue hung from her muzzle.
The ferret girl realized what her friend wanted and retrieved the bulbous sex-toy, bringing the rounded tip close to the vixen's stuffed rear. Adam's cock wasn't even soft when he began to pull out, inch after shiny inch leaving the moaning vulpine until the flare slipped out with a wet 'pop'. 
For a second Nancy's eyes were as wide as Stephanie's poor pucker, until a needy mewl from the vixen brought the ferret out of her trance. She quickly pressed the tip of the plug against her friend's drooling pucker, the vixen obviously straining to keep the well-fucked orifice clenched tight enough to keep the colt's cum inside. The toy slid in easily and the bent-over vulpine sighed as it settled inside her, the little gem glittering between the slightly messy cheeks.
"Mmmmh, I love carrying you around inside me Adam..." the vixen cooed, and Nancy was amazed she could actually see her friend's perfectly trim belly was slightly rounded from the load the young stud had left in her rump. "And now it's your turn!" she gushed, back to her bubbly self.
"Okay, but... uhm... could he, I mean, Adam do you have a condom?" the blushing girl asked timidly as the pair looked at her like someone who asked if they could have some ketchup for their sushi.
"Oh, no, no, no. no sweetie, Adam doesn't use those. It's either bareback in your kitty, or up the butt." She said, the ferret's eyes flying open and one hand shooting behind her to cover her rear at the thought of having something like Adam's cock take her anal virginity.
"It's only that I'm... you know... estrus..." she mumbled shyly.
"Omigosh, you're in heat! That's perfect! Oh Nancy you have to, have to, have to let him cum inside you, he'll give you the most adorable little baby ever! And you'll be the cutest mommy ever, and you're so good with kids, and you're parents are loaded anyway, and I'll be with you the whole time, and I'll be like, the world's coolest aunt, and I'll help you walk it, and change it and feed it..." the vixen began to go on, throwing her arms around Nancy and hugging the ferret tight to her bare chest.
And as she fought for breath in the vixen's cleavage, Nancy began to actually consider it. She did have a very strong maternal instinct, but she wasn't sure if she'd ever want to spend her life with a man. She knew after watching Adam that there was at least one male she found attractive, and the thought of letting the gorgeous young stud give her a foal actually had her rubbing her thighs together, her white cotton panties clinging to her now wet slit.
And she would be graduating long before her due date, so school wasn't a problem. Her parents had been trying to talk her into spending her gap year traveling the world, but Nancy realized that she'd much rather spend both the time and the money nursing a beautiful little foal of her very own.
"Okay, I'll... I'll do it." She said, breathing out and feeling like she just exhaled a ton of anxiety, leaving behind only a good, eager energy.
"You know you don't have to if you don't want to..." Adam said, trying to be heard over the vixen squeezing happily with both hands pressed against her muzzle, although he knew from the look in the ferret's eyes what her final answer would be.
"No, I want to. Uhm, how do we..." Nancy trailed off, the sudden burst of confidence wearing off a little.
"Ooh, I know. Nancy I said I'd help ya and I'm gonna start right now! Adam, since she's giving you such a present, you do the unwrapping!" the vixen exclaimed.
Nancy smiled demurely as the colt went about his task, shocked at the practiced ease with which the boy unclasped her bra and slid it off her shoulders, baring a pair of perky teats with the nipples already stiffening in anticipation. When he slipped her panties off, Nancy blushed when she realized just how wet the bottom was as it was peeled from her needy slit.
Stephanie had wasted no time, plopping down on the couch, her legs slightly parted she patted her lap, inviting the ferret to take a seat. Still slightly surprised, Nancy nevertheless sat down on the offered 'seat', leaning back and sighing at the familiar sensation of the vixen's warm, toned body against hers, the busty cheerleader's perfect rack smooshed up against her back. She'd just managed to relax when her friend grabbed her legs below her knees and pulled them up and apart, spreading the squeaking ferret and kissing her neck softly as she exposed her little flower to the waiting colt.
It was all the invitation Adam needed, the colt's legs moving on their own at the thought of a fresh conquest. Stephanie was fun, as always, but there was just something about an eager female in heat, presented and ready to have a pretty little foal planted inside her that stirred the stud's instincts.
Nancy was panting at the sight of the colt's glistening cock as it moved closer and closer to her exposed lips. The shaft had looked intimidating before, but now she knew she wanted, no needed to feel every inch of that equine spire stretch the velvety walls of her sex as it throbbed in time with the young stud's heart.
Even though she was already spread and on display, the ferret's fingers went to her little slit, prying her soft lips apart to give her young stallion a glimpse of the silky pink of her love-tunnel. She gasped as the trumpet-like head pressed against her slit before slipping in, her legs tensing as her sex wrapped itself around the invading shaft.
Despite the fact that that she'd never been with a guy, Steph had used some pretty impressive toys on her over the years, and Nancy wondered just how long the vixen had been preparing her for the colt. Still, she was grateful to her friend who was even now lovingly nibbling on her neck as the young stallion slowly pushed himself into her, inch after inch of hot, hard horse-flesh spreading her like no toy ever had.
After her young lover bottomed out inside her, the ferret moved her hands up and began to tweak her little nipples, her mouth hanging open as the panting girl gave her stud a brief nod, urging him to breed her. She bit her lower lip as her lover withdrew almost all of his shaft, the sight of her splayed lips clinging to the slick length almost enough to make her cum then and there. And when the colt pushed himself back inside her in less than a second, she did, letting out a long, shaky moan as her vision began to dim.
Things got a little fuzzy after that. She remembered her hands flying out, wrapping themselves around Adam's neck and pulling his muzzle to her perky chest. The young stallion didn't need any urging, and Nancy just held him there as he kissed and licked her sensitive nipples, his pace never faltering as he pumped that glorious length in and out of the squeaking girl.
What little she remembered of the colt's rutting seemed like one long orgasm, ecstatic peaks interspersed with blissful lulls, her crotch a mess as her cunny gushed enough to fill the room with the scent of her heat. Stephanie had joined in at some point, humping her hips up and down and bouncing Nancy in her lap. The motion had made the colt's pounding shaft rub and poke new spots inside her, making the ferret's already foggy mind swim.
But she did remember clearly when the stallion came. He'd been rutting her savagely as he approached his climax, bouncing her against the cooing and kissing vixen behind her until he gave one last push and Nancy could see his tail flagging. When she felt his flare balloon up inside her the ferret had gone wild, tearing her legs free of her friend's grip and wrapping them and her arms tightly around her stud, her nails making little furrows in the fur on the colt's back as she felt his tip jut out and kiss her cervix.
 She remembered begging him with what little breath she had, pleading with him to breed her, to make her a mother desperately even as pulse after gooey pulse filled her womb, giving her exactly what her heat-wracked body had been aching for.
She was sure he'd made her a mommy that first time, but she'd asked Adam to do it a few more times, just to make sure...

"Ahh, quit teasing baby! Let me feel that perfect cock under my tail. You've done your breeding for tonight, you deserve a little treat..." a honeyed voice said from the other side of the wall as Josh sighed, knowing he wouldn't get any sleep tonight either.
The voice belonged to his mother, and what made hearing it worse was knowing that the addressee of that lewd statement was his friend, whose sleeping bag was, as always, empty on the floor of the young hippo's room.
The sleepover wasn't really his idea, and neither were any of the others, but his mother seemed to figure they were an excellent excuse to get Adam into their house overnight, so she would pester and pester him until he called the colt's mom and asked if his friend could spend the night over.
It's not that he minded Adam's company. They'd have fun during the afternoon, playing games and hanging out, although Josh's mom would find some reason to always interrupt, usually wearing as little as possible. And she'd insist on an early bed time for the two 'growing boys', rubbing her thighs together as she said good night to them, knowing she'd be seeing Adam about twenty minutes later.
"Oh God yes! Deeper honey, make me squeal! "
The young hippo's ears flicked back in a vain attempt to block out his mother's cries even as his cock twitched at the sound of her lusty voice. His mother had always looked good, because even though being a hippo meant she was pretty heavy, the weight was in all the right places. But after leaving dad, she'd started working out a lot, and even though she didn't seem to lose a pound, things got a whole lot firmer.
As the woman who gave birth to him really did begin to squeal, Josh tried to cover his stubby ears with his pillow, knowing from experience that it was no use. Adam was about to get started, and once he did the real noise would begin. Not to mention the plaster raining down from the ceiling above him...
On the other side of the wall, the colt gave Amanda's bubbly cheeks a good, hard squeeze, feeling the taught muscles under the soft, smooth skin covering the hippo gal's pillowy behind. The moaning female dwarfed her young lover, but that's what Adam loved about her. He could get as rough as he wanted with her, even when his shaft was buried in the motherly hippo's ass as it was now, and Amanda would only beg for more, for him to go faster, harder.
Her curvy body could take anything the young stud could dish out, jiggling and shuddering with every jarring impact, every loud smack of flesh on flesh. The bed they were doing it on could also take the abuse, since the solid-steel frame was built with a pachyderm couple in mind, but the room was showing the signs of their wild rutting. The floorboards were gouged in places where the four bedposts would jump and scratch at the wood with every lunge and the wall behind the head-board was a mess. Although Adam was still going slowly for now, relishing the sensation of his cock sinking into Amanda's tight vice-like ass.
"Oh Adam, I swear to god, no man has ever filled me the way you can..." the motherly hippo moaned out, delighting in the sensation of her stud's cock as it slid between her plush cheeks even as his seed dripped from her slit.
"Aw, I'm sure you're just saying that. After all your husband..."
"Hah! I wouldn't trade you for ten of him! Useless wretch could only make me cum with his tongue, and even then I had to do half the work myself. And then he has the nerve to ask me if I'm seeing someone else!" Amanda said, remembering the conversation.
She'd taken one deep breath, and admitted to her husband just who she'd been cheating on him with, and why. The marriage wasn't working out and the two had intended to get a divorce once Josh was off to college, but she'd demanded they get it done with right away, and that if he made any problems for her she'd tell everyone who she'd cuckolded him with, even if it meant her going to prison for sex with a minor. It had been a wild bluff, but all her husband really had was his big, blustering macho image, and she knew that it was bad enough for him to know he was out-performed in bed by a twelve year old without everyone else finding out.
After that she started seeing a lot more of Adam, and as his cum sloshed around in her fertile womb, she hoped tonight would be the night he planted his foal inside her. She'd been on her back while he pounded away between her legs, pressing his muzzle between two tits that would have been the envy of a dairy cow, a thin sheen of sweat making her rosy-gray skin glisten in the dim light. As she lay on her belly, those same mammoth tits were squeezed beneath her chest, spread out enough to give the colt behind her an eyeful as he prepared to claim her ass.
She'd never even considered anal sex before she met Adam, and certainly had no intention of trying it with her husband, who had trouble enough satisfying her conventionally. But when her young stud had asked her if he could be her first, she couldn't say no, and was now glad she didn't. She could feel the base of her little tail twitching as her back-door was stretched taught around her stud's prodigious length, the cum-slicked shaft gliding effortlessly between her plump cheeks.
"Ready Amanda?" the colt asked, calling her by her first name, something she'd insisted on ever since the divorce.
"Yes honey, don't make me beg. Please, give it to me like only you can!" she husked, clenching her pucker around the base of the colt's shaft to prod him on.
When she felt his grip shift from her cheeks to her wide hips, she knew she was about to get what she wanted. The young stallion pulled out slowly, making the hippo femme gasp when his medial ring slipped past her slick pucker, the rest of his cock following until only the head was left in.
His thrust was lightning fast, a brutal stroke that sheathed his entire cock in the squealing hippo in the blink of an eye, the force strong enough to make the bed jump as his hard body smacked loudly into her bubbly behind. Amanda didn't bother muffling her cries of joy, and Adam felt a little bad for his friend, knowing he wouldn't get a wink of sleep this night either, but figured Josh probably wanted his mother to be happy, so maybe hearing her like this was a good thing?
The motherly hippo had been teasing him all day, the way she always did when he came over, ensuring he'd be riled up and ready to go once the lights were out. She'd been walking around in a fluffy bathrobe open enough to give the young equine a good glimpse of the hippo's cleavage as her breasts strained against the fabric, and more than a glimpse whenever she'd bend over to clear the table he and Josh were sitting at.
Amanda was in heaven, enjoying every savage thrusts of the young stud's hips as his rutting made her plump behind turn a little rosier with every smack. She could feel the heat deep in her loins, the lingering ache of the colt's vigorous breeding and couldn't wait to feel the same delicious soreness in her luscious rear, a smoldering fire not even the young equine's spunk couldn't put out.
Adam could tell Amanda was close to another climax, and kept his eyes trained on her head despite the tantalizing sight of the hippo gal's cheeks bouncing wildly with every thrust of his hips. He could feel her tightening up, her back arching as she tried to get as much of him inside her as she could, and then it happened. Just as the curvy female let out a long, shaky moan to voice her climax, her stubby ears began to twitch and flicker furiously on top of her head, a sight Adam had always found strangely endearing and that no other female seemed to display.
Josh was spared the sight of his mother's twitching ears, but not the sound of her obvious climax, although apparently not Adams since the thumping and the thudding of his friend fucking his mom's brains out continued unabated. Letting out an exasperated sigh, the young hippo grabbed his own stiff length and began to stroke it, feeling ashamed of himself but unable to resist the sounds of the savage coupling taking place on the other side of his bedroom wall.
Neither of the two lovers knew what was going on next doors, nor did they care, Adam's sweat now dripping onto the moaning hippo as he pounded into her with every ounce of strength he had. None of his other lovers would have been able to withstand that, but Amanda just moaned out happily, begging him not to stop.
Her stubby ears had done quite a lot of twitching by the time her young stud had shoved himself as deep inside her as he could, groaning as his cock flooded the hippo's plump ass with ropes of warm stallion spunk, the motherly female cooing in delight with each gooey spurt of the panting equine's shaft as her lover stretched out over her back, seemingly spent. But as Amanda drifted off to sleep, she knew she had about two hours before she was woken by her stud as he began to rut her yet once more. Ahh, to be young again! she thought, not envying the colt his youthful energy as long as he spent it with her...
*******
Adam took a break from unpacking and allowed himself a moment to just stare out the window of his new room, eyes zeroing in on all the new females walking in the late spring afternoon. The move had been his idea, and like most of his ideas, his mother was quick to support it. Adam felt in the mood for a change of scenery - a new town, new people, new relationships. Sure, he'd miss the female friends he'd made back home, but he felt it was okay since he'd left almost all of them with a foal or two to keep them company.
He smiled as he remembered the farewell party. The mothers of every one of his friends, and indeed every kid he went to school with, had turned up with the convenient excuse that their child was saying farewell to a friend, and they merely tagged along. Most of the others had turned up as well, not minding that they had no real excuse to be there whatsoever. His dad must have felt weird, being the only adult male in attendance. Well, not quite... the colt thought, remembering Mr. Phillip's sullen yet blushing face among the feminine throng.
It seemed to Adam that he'd spent the whole party being passed from hug to hug, most of them a little awkward due to the bulging bellies of the expecting mother's hugging him. Many of the females had commented that the town won't be the same without him, and a number had mentioned plans to move, coincidentally quite close to where the colt would be living.
There were a few who couldn't hold it together and broke out in tears, but fortunately the place they had rented (once it was clear they wouldn't be able to accommodate all the guests in their house) had a roomy storage area where Adam had managed to console the sentimental women in the way only he could. 
In retrospect, it might have been a bad idea, since once the others noticed the colt leaving with one teary-eyed female and coming back with the same woman floating on air, if a little bow-leggedly, they all turned on the water-works. It was the first time Adam had had so much sex that he actually felt exhausted, but he figured he owed it to the ladies who'd been so close to him all these years. And when they were leaving, people actually lined the streets on their route to wave them off. The women and girls looked sad to see him go, but most of the men looked relieved, apart from those standing next to gravid wives and daughters who had sour looks on their faces, but waved none the less...
But as bitter-sweet as the parting was, the young colt was sure the change of scenery would do them all good. His mother had been thinking along similar lines, and as more and more of the women in their town (and quite a few girls) began to give birth to beautiful little fillies and colt's she knew that it would be best if Adam wasn't around when they started growing up, since the resemblance would be impossible to hide. 
Adam's dad had been surprisingly easy to talk into the move. The stallion had been getting job offers from various other towns, but had so far turned them down, not wishing to force his family to move just for the sake of his career. Their new home was wonderful, a vibrant little college town that Adam's parents figured would be handy, since their son wouldn't have to leave home for his studies (an idea that Adam's mother found particularly appealing). Coincidentally, it seemed almost all the girls in his school's graduating class would be attending that very college soon, apart from those who'll be taking a year or two off to wean their little foals.
The colt, on the other hand, knew that it wouldn't work out that way, and was pretty sure that by the time he was ready to enroll he'd already be far too familiar with the female students and faculty. After all, a growing boy like him had needs...
