Climbing the stairs of her house with a basket full of freshly ironed laundry, Laura hadn't expected anything particularly life-changing to happen. She'd heard the shower upstairs was running and figured her son would appreciate some clean clothes ready for him once he came out. As it turned out she'd timed it quite close, close enough apparently for her to catch her son coming out of the bathroom.
"Sweetie, I've just ironed your favorite shirt if you want to- oh my God!" she squealed out the last words, the laundry-laden plastic basked falling as both her hands flew up to cover her mouth.
"What's wrong mom?" her son asked, standing naked in front of her with the towel that should have been wrapped around his waist clutched in one hand. The twelve-year-old's question was sensible, since it shouldn't have been a shock to his mother to see him naked. The frazzled mare struggled to look her boy in the eye as she frantically tried to think of an answer.
It was certainly true that she'd seen her foal without a stitch on plenty of times, but Laura had never in her life seen so much of him. She had noticed her boy was growing, feeling both a bit sad that he wouldn't be her little baby anymore, but also proud at what a handsome stallion he was shaping up to be. And if she'd been feeling any of that, it would have been no problem. But her son was unmistakably in puberty and she'd caught a glimpse of parts of him that were already almost stallion-sized.
"N-nothing honey, but you really should wrap up before leaving the shower..." she said, looking to one side and using a hand to block her view of her boy since her pupils seemed glued to him even as her head turned.
"I know but lately it's been getting like this whenever I wash it for some reason, and I can't even get the towel around me..." he said, gesturing with his eyes at the inconveniently erect pillar of mottled flesh, still unsure why the sight of it suddenly had his mother this flustered.
"Oh... well let's just... Let's just go to your room and talk about this..." she mumbled, quickly bending down to pick up the laundry. That proved to be a mistake since it brought her muzzle level with the tip of her son's shaft.
The colt's fur was still damp, his mane and tail still in lanky strands after a quick towel drying and they smelled mostly of shampoo with a hint of the earthy smell of wet fur. But the maleness bobbing from between his legs had a scent of its own, a fragrance that seemed to circumvent the mare's sensibilities and stir certain instincts.
Those instincts definitely didn't subside when she was alone with her colt behind a closed door, but she took a deep breath to steady herself, reminding herself that it was a child standing in front of her - her child, in fact - despite how early and... well he was developing. Some part of her insisted it would be a better idea to just get out of the room and let her husband know he might need to have a 'growing up' talk with their son, but she dismissed the idea. What sort of mother runs away from her boy just because his body was reacting normally to the changes he was going through?
"Now sweetie, it's perfectly fine that your... that you got a little stiff. You see, you're growing up and that part of you was probably reacting to the sensation of being rubbed when you washed it, although hot water is sometimes enough to get a stallion to drop..." she said, remembering hot showers she'd shared with her husband that ended up making them even messier than before they came in. The thought was not helping her think straight, so she quickly pushed it from her mind.
"Well how do I get it to go down? It's happening more often, and sometimes in school I can feel it start to swell up."
"Oh! Uh well..." the mare said, wondering if it was too late to pass the reins. But the mention of school made her stay. There were all these news stories about female teachers preying on young boys, and she didn't want some hussy getting ideas just because her son had an involuntary reaction during class.
"Well you'll probably have special classes at school soon, where they'll teach you all about... how your body is changing, but... Well honey that part of you is what makes babies. Y-you put it in a mare and... after a while white stuff comes out, and it stops being hard..." she managed to say, almost biting her lip as she visualized that hard young length pressed against a winking slit, the flare of it dimpling some lucky mare's eager lips before they gave way and clenched around the mottled rod. "But you're still way, way too young for that!" she quickly added, realizing she might have suggested an entirely unacceptable solution to Adam's not so little dilemma.
"So what boys your age do is that they sort of grip their... penis... and just stroke it until... it happens." She said, her eyes going wide as Adam calmly gripped his swollen shaft and gave a few experimental strokes.
"I don't think it's working. This sort of thing usually only makes it harder..." Adam said, surprised at how flustered his mother was getting. He noticed that ever since he started growing women tended to look at him a little differently, but those were all little glances. The mare that had given birth to him seemed unable to take her eyes off his stiffy and no longer bothered to hide it.
"Ahh, well I'm not surprised. After all you can't... can't even make your fingers meet..." Laura replied, her breath hot and a little labored as the sight of Adam's hand failing to encircle his member only made it look even bigger and more tantalizing. "Here, let me... I mean, I'll show you how to do it. Just this once..." she heard herself say and before she knew it one of her hands was wrapped around the colt's cock.
She knew she was going too far, that she should stop right now and come to her senses, but when her son's length throbbed in her grip, she knew that she wouldn't be doing the sensible thing. Just this once... she repeated, this time to herself. She knew she shouldn't be doing this. She was a married woman, and her husband was... well, at least he was in the garage, happily tinkering with the family car and unlikely to finish before Adam did. And it's your son! A voice in her head hissed, reminding her that there was more things wrong about this than mere infidelity. Well it's not like I am going to have an affair with my foal! she thought to herself, feeling a little reassured at how ridiculous the notion was. She was just... being a good mother and teaching her boy how to deal with his changing body.
She wasn't sure when her other hand had moved to cup Adam's sack, but the grunt coming from the young stallion kept it there. It matched the equine pillar in size, the orbs swollen and heavy considering this would be her boy's first orgasm. She stroked the colt's length just a little faster at the thought of that bulging pouch twitching as it pumped out its load.
"H-how does that feel sweetie?" she said, her voice shaking a little as her own body reacted to what she was seeing and what she was doing.
"G-good. I feel something but it's like I'm just getting more tense..." her son replied, and his tone made the mare's ears flick. The still boyish voice had a masculine strain to it, a very familiar and unmistakable one to the mare's ears.
"All right sweetie I'll just... I'll try something else, but it's going to be something special that we do just once. You'll learn how to do it yourself later..." she told her son even as the hand that had been cupping his pouch began to undo the buttons of the blouse she was wearing.
Despite having a foal Laura worked hard to keep her figure firm if a bit lush, and when she was just pottering around the house she generally didn't bother with a bra. She finally managed to get enough of them undone to open the shirt and reveal her full breasts, two ripe mounds covered in fur the color of rich cream.
She couldn't stop her lips from curving when she saw her son openly stare at the exposed expanse of feminine charms. His eyes remained glued to them as she pushed her heavy breasts together around his length, trapping her son's prodigious appendage close enough to her chest that she was sure he could feel her heart beating through it.
"There honey, now just relax and... let it happen..." she said, her voice coming out breathy right next to the colt's subtly flared tip. The sensation of his length sliding across the soft fuzz of her cleavage seemed to stimulate her son more than her hand did, and soon his eyes were getting glassy, the room filing with the scent of an amorous stallion as the slightly trumpeting tip leaked down the mottled shaft, every errant drop soaked up by the rising and falling breasts of the almost panting mare.
"Mom, I think I'm gonna..." her son grunted, snapping Laura out of a pleasant daze. Her eyes had been glued to her boy's cock, noting every throb and twitch, watching the mess run down form the flare in hypnotic little rivulets, her nostrils flared and her eyes wide as she mechanically went up and down the prodigious length.
Her son's grunted announcement brought on the realization that those swollen, pent-up orbs were about to shoot for the first time, making a very big and very damning mess. Since it was clear by the way her boy was panting that there was no stopping at this point, Laure did what had seemed like quite a sensible thing at the time. She opened her mouth wide enough to let the flaring tip past her lips, pressing her breasts tight against the throbbing length and suckling on it just as the while thing began to twitch.
Laura had never minded swallowing when she went down on a lover, even though with equines this did always present a challenge. And as skilled as she was dealing with a stallion's torrent she was still caught by surprise by the first blast of thick, warm cum flooding her mouth before she managed to gulp it down. It was a struggle to keep up with her son's load and she could imagine those heavy, swollen orbs twitching as pulse after pulse of colt-cream traveled up the throbbing length. She managed the first few spurts, but after that it was all he could do not to drown as her son just kept coming, the gooey seed actually coming out her nose and leaking around the seal her lips formed just below the flared tip.
By the time her colt's orgasm had subsided and the mushroomed head shrunk enough to pop out of her muzzle, Laura was feeling almost faint. She gasped for breath, every inhale carrying the scent of her son's cum as she watched the majestic shaft soften, thankfully as exhausted as she was. She licked her lips clean, erasing the damning evidence of what she'd just done as well as savoring the taste of a fresh young colt. Her hands were still shaking as she did her best to button up her blouse, hoping that she hadn't gone too far and that her son could still see her as his mother and not just an eager mare with poor self-control.
"Now honey we need to... let's just keep this our little secret, okay? This isn't really the sort of thing boys do with their mothers, but we had to get your little problem under control, so it's okay..." she said, finally getting up from her kneeling position and going wide-eyed as the movement caused the fabric of her panties to shift against her crotch. There was no mistaking it - they were soaked! Laura knew that her pale fur did little to hide a blush and she hoped the one spreading across her face wasn't showing. At some point during her son's climax, as she'd struggled to drink down everything that majestic young cock was serving her she must have had a climax of her own, without being touched or even touching herself. That was a first for the mare and she found herself unable to meet her son's eyes as she beat a hasty retreat out of the room. If the shaft that was still half-erect rose again, she wasn't sure she could trust herself...
*******
Lifting her mane from her eyes, Laura squinted at her bedside clock, only to find out it was just past one in the morning. The mare had hoped that the bit of sleep she'd managed to catch after squirming around under her blanket had been enough and that she could just get up and get an early start on her day, but it had barely been an hour, and she felt too restless to try and go back to sleep. After her episode with her son she'd hoped she could get her husband to help her work off the energy fooling around with Adam had filled her with, but her stallion was feeling worn out and had missed both the subtle and not-so-subtle signals she'd given him.
Her thoughts then turned to the colt across the hall - youthful energy in a body that was slowly blossoming into a stallion no woman will be able to resist. That thought seemed to propel her, and before she could even consider it she was out of her bed and quietly making her way to her son's room. She assured to herself she just wanted to check if her foal was sleeping soundly, and that if he was she'd get back to bed and try to do the same.
She didn't really have a plan for what she'd do if he wasn't, but that didn't stop her from putting one of her big ears against the door to Adam's room as she tried to hear him over the pounding of her heart. Instead of a silence she heard a rhythmic sound and muted grunts, enough to banish all reason from her frazzled mind. She gave a soft knock but didn't wait for a reply, her hand shaking as she opened the door and peered inside.
She'd caught sight of Adam just as he'd wanted her to - sitting on the edge of his bed with nothing on and his cock sticking up straight and hard from his crotch. The colt had also had a hard time falling asleep, and had almost nodded off when the sound of quiet footsteps roused him. When they'd stopped just outside his door he wondered if the events of that afternoon had effected his mother the same way they had him, and decided to put on a little show, grabbing his half-tumescent length and giving it a few strokes, grunting to make sure he could be heard by anyone taking the trouble to listen in.
"Adam! I was jus... that is I... a-are you okay?" the mare did her best to speak, the sight of her son having robbed her of her breath as well as her sensibilities.
"It got like this, and I can't seem to get to sleep..." Adam said, switching on his bedside lamp and gesturing to his erect shaft, carefully omitting the fact that it was his stroking that had gotten it up.
"Oh! Well you really need to get some rest. It's a school day tomorrow..." the mare said, her eyes glued to the bobbing length as her mind quickly worked out to rationalize what her body desperately wanted. "L-let mommy help you... just this once..." she husked, sliding the straps of her nightgown off her shoulders and letting it slide off her.
The fact that this was wrong didn't enter her mind after the way she saw her son eating her up with his eyes, her nipples stiffening and her marehood dribbling as it winked in anticipation. Her tongue flicked over her lips at the thought of getting another taste of that magnificent shaft, but she knew that would only leave her even more frustrated. 
"Adam, there's something we could do... something you should only ever do with a girl you care very, very much about..." she said, trying to pull her eyes up from the leaking tip of the equine shaft in front of her long enough to meet her son's. When she finally did, it proved no less beguiling than staring at his cock.
He looked at her the way no boy his age should have looked at a woman, especially his own mother. She knew Adam had been ignorant of sex until that afternoon, but he still had the confident gaze of a stallion that knew what he wanted, his eyes brazenly yet lovingly eating up the sight of the naked mare now standing in front of him.
"Lie down on your bed sweetie..." she said, knowing she should stop but knowing just as well that she couldn't. Not unless her colt told her to.
Part of her still couldn't believe what she was doing as she climbed into bed with her son, kneeling on either side of his hips and feeling her sex wink frantically enough to scatter droplets of mare nectar over the boy's coppery fur. She got on all fours over him, her mane falling down and covering one side of her face as her rock-hard nipples gently brushed over the colt's muzzle, the heat of his breath against her breasts almost making her whimper.
She reached down with one hand, guiding the slick flare in the dim light, her hand trembling but managing to bring the blunt tip to her needy slit. She froze for a second, some still sane part of her refusing to take this last step, and she might have wound up re-thinking the whole thing if her son hadn't taken the initiative. One buck of his hips was all that it took. His glans was mashed up against her lips, spreading them just a little until the sharp jab drove the flare into her, dispelling the last trace of reason and reluctance.
Laura's eyes rolled back as she pushed against the hot spire invading her, her eager cunny swallowing her son's shaft as the silken walls of her sex reveled in the taboo act. Despite the fact that she was a mare and a mother it was a snug fit, and Laura couldn't help but wonder just how much growing Adam would wind up doing. By the time the medial ring had slipped past her lips and she took the last few inches she could feel that the flare had almost but not quite bottomed out inside her. A near perfect fit, and a member women will struggle to take in the future.
"Ooohh Adam! T-thank you baby... thank you for letting me be your first..." she mumbled, kissing the top of the colt's head as he buried his muzzle between her hanging teats. Her now impaled slit was still winking, happily pulsing and squeezing around the thickest portion of her son's cock.
She knew she wouldn't have long. Even after emptying himself down her throat earlier that day, her colt was still just a very gifted boy and this being his first time she figured he'd have a short fuse. Fortunately she was so worked up she doubted it would take much to set her off. Just sliding off her son and feeling that ring slip out of her made her walls clamp down around the throbbing length buried within her.
Adam seemed to be enjoying himself, huffing lovingly into her cleavage and rubbing his face in her chest, so she did her best to move as little as possible and let him have his fun. Her back arched in and out as she slid herself on and off her son's cock, never letting more than a third of the thick length leave her before she pushed back and took every inch of the colt's spire. She was biting her lip to stifle her noises despite how much she wanted to let Adam now how he was making her feel. Still, she was pretty sure he had an idea, considering the mess being pumped out of her well-stuffed marehood and all over his crotch.
She failed to muffle a keening moan when her colt's moth found one of her nipples, the young stallion instinctively drawing the stiff nub deeper into his mouth before flicking his tongue over it. The mare's eyes shot open, her mouth agape as she drove herself back on her son's cock and just ground herself against him. Strange panting noises were leaving her muzzle as her whole body trembled, her climax surprising her with both its force and swiftness. She lowered herself on top of her son, the feeling of a firm young body against hers only serving to prolong her blissful episode as her pulsing sex did its best to coax a load out of the shaft throbbing within it.
"Oh God! Just... wait a sec sweetie, and I'll - oooOooff!" she began when she suddenly found her limp body being flipped over and her son's weight settling on top of her.
Adam had almost flipped them out of his bed and the mare wound up with one leg dangling off the mattress, only serving to open her up even more for the colt now bracing his forearms on either side of her. One of her hands flew up just in time to cover up her muzzle and muffle what would have been a squeal as Adam gave a short buck into her.
A second followed the first, the young stallion drawing half his cock rom his mother's dripping sex before ramming it back in, the erratic thrusts soon falling into a vigorous rhythm that no boy his age should have been capable off. Laura's climax hadn't even tapered off when her son began to rut her, her over-sensitive walls twitching as the veiny length slid in and out of her. Her ears were filled with loud, wet smacks as Adam's crotch slammed against her own, the colt grunting softly over her as he took her like she was an eager young filly rather than the mare that had given birth to him.
"Like that baby, like that... You're doing... oh my God!" she babbled, trying to keep her voice down as her son pistoned tirelessly away. She could feel the clap of his heavy sack as it hit her cheeks on every thrust, realizing that with her son on top of her she was no longer the one calling the shots, such as where those balls will be emptying themselves when Adam reached his climax.
With what little sense was left to her, the mare tried to think. She wasn't in heat, and wouldn't be for a little over a week. Theoretically she was safe, or at least reasonably so, but the memory of the load her son had blasted down her throat earlier that day filled her with doubt. But the thought of feeling that torrent let lose inside her made her heart flutter, and she supposed that since this was her boy's first time - something he'd always remember - she owed him something worth remembering.
Resigned to her fate, Laura lifted her legs and folded her knees, trying to give her colt as much access as she felt his cock stroke all the right spots inside her. He was nuzzling her neck now, the hot huffs of his exhalations tickling and thrilling the mare as her own child gave her the breeding of a lifetime. She'd laid under him so long that she was sure her second climax would hit before Adam had his own, but the sudden tightens deep inside her told her the colt was as close to coming as she was.
"It's okay baby, come inside me... fill mommy up..." she murmured, too lost in the sensations washing over her to pay attention to what she was saying.
With every beat of Adam's heart she could feel his flare grow just a little bit bigger, the swollen tip still sliding around inside her and making her whole body twitch. Adam's rhythm began to falter, every push forward becoming a little harder until he gave one shove that made the bed jump and Laura's legs lock around him.
She almost whinnied when she heard her little stallion grunt, the massive shaft buried to the hilt in her throbbing until warmth blossomed out deep in her body, the tangible proof of her young lover's climax serving to intensify her own. She held him close to her as he emptied himself inside her, unable to believe the sheer volume of hot, gooey spunk being pumped into her, forced deeper by the colt's massive flare.
It had looked even bigger than it felt when it finally slipped out of her, the mare frantically pressing one hand against her mound to keep what she was sure was a pint of colt-milk from gushing out all over her boy's bed. She kissed him good-night in a less than motherly way, especially when Adam kissed her back, and managed to make it to the bathroom without making a mess in the hallway. She cleaned herself up as best as she could, since now that her frustrations were gone her body was demanding sleep rather than a male. As she lay down next to her husband, she told herself that whatever this had been she'd gotten it out of her system, and in the morning it would be back to life as normal. But when she'd woken up after Adam-filled dreams to find her inner thighs were drenched, she knew her relationship with her son would never be the same...
*******
 "My, my! Who's this young stallion?"
The voice greeted Adam as he reached the bottom of the stairs, making his ears perk and his head turn towards their living room. Once it did the speaker wasn't hard to spot, which he suspected was how Mrs. Warren liked it. The feline wasn't actually flamboyant, but she had a certain zest for a life and a flair one didn't expect from a minister's wife. Still, she was originally from France so most people wrote it off as a cultural thing. Adam, for his part, wasn't so sure. A boy his age would often put on a polite and well-behaved façade when dealing with adults, and he suspected that the green feline having tea with his mother did something similar...
"Oh, just my son. Adam, come in and say 'hi' to Mrs. Warren..." Laura said, her cup clattering for a second before it settled on its saucer. The way her guest had referred to Adam brought to mind brief flashes of his decidedly stallion-like aspects and threatened to make the mare blush.
"Mhh, so it is young Adam! You've grown so much I almost thought your mother had a younger man over..." she said, delivering a scandalous accusation in an innocently playful tone.
"Well you do see me every Sunday Mrs. Warren..." Adam replied, finding his lips curving to match the feline's smile. Normally it was always a boring chore whenever his mother dragged him over to say hi to her friends, but in the light of recent events he found he was eager to talk to an older woman, especially one as beautiful as the one sitting in front of him now.
"Brigitte, please..." she replied, a twinkle in her slitted eyes suggesting she was enjoying the attention of a young male just as much as Adam was enjoying hers. He found his eyes wandering over her body, and not for the first time. Being a manticore, Mrs. Warren had the grace and the fur pattern of a tigress, although hers was done in shades of green, as was her hair. She kept it cut short enough that it reached down just past her jawline, and styled in such a way that didn't hide a pair of short, bright-green horns growing from just above her forehead. 
There was also the scorpion-like stinger at the end of her tail that he and his friends had always thought could deliver a deadly poison with one swift strike, but her mother had assured him that these days manticores got their venom glands removed shortly after birth. He remembered feeling a little disappointed when he'd heard that, but he supposed Brigitte didn't really give off a femme-fatale vibe. She was always kind to people and adored children. Especially boys, now that he came to think of it.
"Laura, I don't suppose I suppose you could loan me your son for tomorrow? Nathan is off on a retreat and I have some yard work I could use some help with..." the manticore asked, and Adam was surprised at how flustered the question had gotten his mother, even though she was trying to hide it.
"Oh... of course! I'll send him 'round right after school..." Laura replied, doing her best to get a grip and remind herself that Brigitte surely didn't see Adam the way she saw him ever since they crossed boundaries they probably shouldn't have. And if she wanted to keep their little secret just that, she couldn't afford to act like a woman who'd just been asked to share her lover. Not that Brigitte would ever... she thought, trying to purge her mind of the image of the green feline and her son together. Just because she'd given in to her lust there was no reason to assume other woman would too...
*******
"There! That's the last of them..." Brigitte said, carefully patting down the loamy soil. She surveyed the spots where leafy green stalks stuck up from the ground, each one crowned with a heavy bulb that would soon open into a flower.
"That was quick. Not really sure if you needed me..." Adam said, getting off his knees as he finished planting his last one.
"You don't think I had some ulterior motive to get you here, do you?" the manticore asked, the playful lilt in her tone suggesting the idea wasn't exactly far-fetched. "Besides, it's not a bad way to spend an afternoon, is it? In a garden, with a pretty woman, working up a sweat?" she asked, subtly trying to gauge Adam's reaction. It was an entirely inappropriate statement that would have had a boy his age blushing for one reason or another, but there was a peculiar confidence in the colt standing beside her, even if he didn't seem to know how to take initiative. "Mhhh, just smell that air..." she said, taking a long, luxurious inhale of those flowers which were already open, filling the meticulously manicured garden with a rich mix of fragrances.
Adam joined her and took a deep breath, but it wasn't flowers he was thinking of. His eyes were glued to the voluptuous feline as her deep inhale made her chest swell up, pushing her full breasts out until her nipples stood out clearly against the thin fabric of her sundress - the only article of clothing she wore apart form a wide-brimmed straw hat.
Brigitte held her breath and her pose for a little longer, seemingly ignoring the young man until a glance at him told her he'd taken the opportunity she'd given him to get an eyeful. She wondered if the colt would stop at that - a stolen glimpse of something he shouldn't have seen, or at least stared at. Somehow she thought not. He had the look of someone who'd take anything he thought a woman was offering him.
"Oh my! Things are growing all over, it seems..." she said, shamelessly pointing with her eyes towards the colt's crotch where a promisingly heavy outline could now be seen. There was a limit to the boy's confidence, and the feline's slitted eye caught the suggestion of a blush and the slight fold of his ears. But he did nothing to hide what she was brazenly staring at, even when his shorts grew just a little bit tighter. "Don't be embarrassed, a boy your age can't help those things. Especially in a place like this, where it is quite literally in the air. You've learned about the birds and the bees, hmm?"
"Yes." Adam replied, and something about the tone and the swiftness of his answer made the manticore's tail twitch. So sure of himself, this one. And so big for his age... Brigitte thought. She'd had a little fantasy for a long time, about her seducing a beautiful boy like Adam and making a man out of him, a fantasy that had never seemed as real as it did now. In her mind she had two choices - do something tawdry and reckless, or do the sensible thing and regret it for the rest of her life. It wasn't a hard choice...
"Adam, if I told you you could do anything to me right now, what would your answer be?" she said, taking off her sunhat and running a hand through her hair.
"I'd... I'd like to touch you." The colt replied, his voice wavering at first but not as much as it should have. A boy his age should have been blushing like a beet, too stunned to speak. And once he found his voice, most boys would have asked for a glimpse, a peek. Maybe to see all of her even, but that clearly wouldn't be enough for the colt now standing in front of her and openly eyeing her buxom form.
"Hmm, a good answer. But a bit obvious..." she said, making sure to swing her hips as she took a few steps closer to the young equine. "It's normal for a young man like you to want to touch, and any woman that makes such an offer would want to be touched. But a more romantic move would be to ask for a kiss. After all, you don't simply give someone what they want. You make them want it more. Tease them a little, and when they get what they desire, they'll be even happier they did..."
Brigitte bent over a little, bringing her lips closer to the colt's muzzle as if daring him to kiss her. Adam managed to unglue his attention from the manticore's chest, her posture making the heavy feline breasts strain against the thing fabric of her dress. He was still a little tentative as he brought his lips to hers, but the manticore's low purr of delight filled him with confidence. He could see her point and had managed to keep his hands from rising and seeking out those supple globes he knew were invitingly within reach. And just as Brigitte said, when their lips parted he was left wanting her even more, and by the look on her face it had worked both ways.
"Can I see more of you?" the colt asked, the boyish voice filled with a confidence no child should have possessed. Brigitte was no longer entirely sure who was seducing whom here, but if the young stallion wanted a better look she was certainly eager to give him one.
Well, she was eager for something else, to tell the truth, but she took her own advice and took things slow, teasing both the boy and herself. She carefully pushed the straps of her dress off her shoulders, shrugging them off a little until the neckline fell, the gossamer-thin garment now held up by her impressive chest, almost hanging off her stiff nipples.
She tugged the dress down a tad further, giving the boy a glimpse of her areolae as she held it up a little longer before letting it slide off her and pool around her legs. There was a hunger in the colt's eyes, and the shorts were now looking painfully tight, but she'd expected something different from a boy seeing a naked woman for the first time.
"Now can I see more of you?" she asked, subtly cocking a hip and swishing her tail behind her, the very image of sensual playfulness. The boy took his clothes off quickly and without much showmanship, but Brigitte wasn't really interested in a strip-tease. His body looked for the most part like a colt promising to grow into quite a handsome stallion - a firm and lanky frame hinting at future muscles but still more boyish than manly. But once her gaze fell so did her jaw, her eyes going wide at one part that seemed fit for a stallion already. She could feel her sex moisten at the thought of that flare pressing against her lips and just how snug a fit Adam's cock would be once she got him inside her.
"My, my... You've grown more than I thought..." she said, a feline husk creeping into her voice as she took another step towards the colt and knelt in front of him.
Her nostrils were flaring as the scent of her favorite blossoms mingled with an even more alluring aroma - the sweet musk of a fresh young stallion, second only to the taste of one. No sooner than the thought entered her head than she brought her muzzle to the base of the equine spire, muzzling his sack for a moment before dragging her tongue up along the underside. She heard Adam gasp and couldn't' help but smile. She was being exceedingly careful, her touch feather-light against the veiny length, but a feline tongue against someplace as sensitive as that was always an intense experience.
She gave the leaking flare a kiss when she reached the top, savoring the taste of her young stallion before kissing her way back down the twitching length. She repeated her little routine, admiring the sight of the colt's muscles twitching as he politely stood still and let her work, her own sex now quite wet as she savored the taste of the equine cock. After she'd teased him as much as either of them could take, she leaned back and lay down on the trimmed grass, spreading her legs and letting Adam see just how excited she'd gotten while worshiping his length.
"Now remember what I said - kiss before you touch..." she reminded the colt who wasted little time, getting on his knees with his eyes glued to the glistening strip of smooth skin between her parted thighs. Adam didn't need to be told twice, and Brigitte's purr when his lips met hers was a good deal louder and deeper than the one she'd let out when they'd first kissed. She felt the smooth, broad tongue lash across her needy slit, cleaning up the mess she'd made of herself before slipping in to seek out more of her honey. She had to fight the urge to clamp her legs shut around the boy's head and keep him there until her thighs gave out and released him, but she knew he'd be ready to move on soon and didn't want to slow him down.
After a few probing licks, the colt took his mouth off her sex, lovingly kissing his way over her mound and up her belly, pausing when  he reached the pair of soft feline breasts that had caught his attention earlier. The manticore petted his mane as he brought his lips of one of her nipples, suckling on it and making Brigitte writhe on the soft grass, thrusting her chest out at the eager young equine. He switched between her lush teats for a while until he slid a little further and the manticore actually felt the heat of his flare against her bared sex.
"Sit up for a second, darling..." she said, gently pushing the boy up before he entered her. He looked confused for a moment but his face brightened when the nimble cat pulled her legs up and grabbed them under her knees, putting her behind on lewd display for him. When he laid himself over her again Brigitte rested her legs against his shoulders, her rear lifting off the ground and angling her sex up so that she'd take very last inch the boy had to give. This position also put the colt in charge and all she could do was await the magic moment when that hard young shaft found its way into her dripping sit.
"A little higher, lover. Let's save that for later, hmm?" she husked when she felt a prod just under her tail. She was tempted to just let Adam sheathe himself wherever he wanted, but she figured she'd make him earn that particular privilege. 
His next prod mashed his blunt tip against her lips, the flared end of his cock spreading her a little but not quite enough to push in. It was enough to stay wedged, and once the boy felt he was lined up he bucked his hips, sending several inches of hard, throbbing stallion-meat into the shuddering feline under him.
"Mmmmhhhh..." the manticore moaned out, trusting the thick, bushy hedges to muffle the sound. "Oooh, Adam! I'm not your first, am I?" she asked, knowing the answer and failing to sound disappointed as a few more deliciously thick inches slid into her. She knew a boy Adam's age should have been overwhelmed when he first sheathed his young cock into a hot, wet cunny like hers, maybe even going so far as to cream himself before he was even all the way in. But the brief pause Adam made before continuing to sheathe himself seemed to be more out of consideration for her than anything else.
"No." Adam replied, seeing no point in lying to Brigitte unless she pushed the issue further. It had been a week since his mother had first crept into his bedroom, and since then he'd been exploring the limits of their new relationship, finding out that there were barely any. But their time together always seemed to exhaust his mother more than it did him, particularly that time when he'd bred her tail-hole, and he figured that there was no harm in having other women to play with when his mom was too tired or too sore.
"Mhh, well I won't pry..." the manticore purred even as the thick base of the colt's cock pried her to her heart's delight. "... but why don't you show me what that woman taught you?" she said, guessing that she wasn't the first grown female who had taken an eye to an exceptionally handsome young colt. Besides, even if a girl Adam's age was curious about boys, she would have been scared off by what she found between his legs. And just as well... she thought. It takes a woman to deal with something like this...
As her lover pulled out she could feel her lips cling to his length, the sublime sensation of his medial ring leaving her sex drawing another purr form her, one that revved up when the colt mounting her drove the whole thing back in, bouncing her rear up a little as his shaft reclaimed her silken depths. She was at the boy's mercy and loving every second of it, soft little moans leaving her mouth as the colt found his rhythm and began to truly breed her.
The thought brought other concerns to mind, but Brigitte waved them off. True, she was feeling her heat coming on, which was probably the reason she was even now stuffed with the young equine's exquisite member, but as gifted as Adam was he was still a twelve-year old. Even if he wasn't shooting blanks, whatever he left inside her would no doubt be easy to rinse away before it could cause any trouble. The thought was sort of a sad one. The baby this colt could leave her with would almost be worth the scandal...
"That's it lover, go as deep as you can... You feel how warm I am around you? How wet I am? That's because I need you darling, everything you have to give as hard as you want to give it..." she husked, her words doing the trick and spurring the young stallion on.
The boy was anything but a virgin, railing her speared slit with smooth, even strokes, the flare within her still not swelling enough to announce his climax. Which was more than Brigitte could say for herself. She could feel her tail thrashing against the grass, hoping it wasn't running any of the flowers she and Adam had planted. But as she felt the clap of his sack against her rear, part of her couldn't help but wonder if the young stallion would wind up planting something else in her garden.
Her excitement was mounting but the tigress was doing her best to let it, knowing that her climax would be all the more glorious if she did everything she could to delay it. In truth, it was a rare treat to have the opportunity. She couldn't remember the last time a male had lasted long enough inside her to tease her properly, at least without her taking his first load down her throat.
The colt on top of her, on the other hand, looked like he could go on rutting her forever. His grunts and the sweet smell of his sweat betrayed his exertion but not exhaustion, his hips rising and falling as he pistoned in and out of Brigitte's now thoroughly messy sex. The manticore felt the claws on her hands unsheathing, digging into the dense carpet of soft green grass even as her toes curled. It was sweet agony now - her whole body aflame and tingling, just waiting for the bliss of delicious release she was denying herself.
The wait seemed to go on forever, and the manticore almost cried out when she finally felt something grow deep within her, recognizing it as a sign of her colt's impending climax. The flare continued to balloon up past the point of discomfort, but even the pain of her velvety walls being stretched to their limits was sweet at this point. She tried to say something, to urge her lover on and coax him into releasing everything he had inside her, but all that got past her muzzle were desperate babbling sounds.
As intelligible as it was, the boy pounding away between her thighs didn't seem to need urging. She felt his tip bottom out, the now massive flare grinding against her cervix a few times before the whole thing began to swell up with the first pulse of the colt's seed. When the first blast filled her the feline's slitted eyes rolled back in her head, her tongue lolling out as the sheer volume of warm equine seed caught her by surprise.
Any semblance of self-control was gone now and she was grateful to the colt for kissing her in time to muffle a cry she was sure the neighbors would have heard. Her tail thrashed and her paws tore up clumps of grass as her mind shattered, her sex milking the shaft that was still blasting a torrent of Adam's spunk as deep inside her as any male had ever reached. The boy had claimed her womb, but then again as far as she was concerned he had earned it, giving her an orgasm that more men than she'd care to admit had failed to provide so far.
She clung to her lover even after he'd finished filling her, desperate to savor the half-erect length buried snugly in her, the still flared tip keeping a warm, gooey mess trapped deep inside. She was still lost in that blissful repose and didn't notice when the cock she was greedily keeping trapped stirred to life. She didn't fail to notice when Adam picked up his pace again, her eyes staring in disbelief that the colt was already about to give her a second rutting when she had barely recovered from the first one.
The motion of his cock churned the mess he'd made inside her and she could feel it oozing over her pucker as the young stallion's motions made room for more. In truth, Brigitte wasn't ready for another go, her well-bred tunnel so sensitive that she almost winced as the trumpet-like tip was dragged up and down inside her. But her only option was to tell Adam to get off her, something she was sure that he would do without complaint. Which was exactly why her muzzle stayed shut...
*******
"Adam, could you stay behind? I'd like a word with you in private..." Vanesa said in her usual measured tone that left little doubt that a politely phrased command is still to be obeyed without question.
The colt gave her no trouble, but also didn't seem to be worried that he was staying behind while the rest of his classmates filed out of homeroom. Most students would either be squirming, or trying their best not to as the basilisk let her stern gaze do its work before she spoke. Supposedly her species could turn people to stone by looking at them at one time in the distant past, but Vanesa found the ability to figuratively petrify a young troublemaker enough. And the irony was that they weren't here to discuss what her eyes were doing.
"Adam, do you know why I asked you to stay behind?" she inquired, giving the boy a chance to confess and apologize.
"No, but it's okay. I'm in no rush to get home..." the colt replied, his tone friendly and undaunted by the stern demeanor of his homeroom teacher. He was acting as if he wasn't singled out for misbehaving, but was rather doing Vanesa a favor by staying behind!
"I've noticed a change in your behavior, and not for the better. Now, I know that you are a growing boy and there are certain impulses you're finding hard to control. I've been teaching long enough to turn a blind eye to an occasional glance somewhere just below my neck, because that sort of thing can happen to a young man by accident. Staring is another thing all together, and I'll have you know I have zero tolerance for intentional disrespect. Is there anything you'd like to say at this point?" she asked, expecting him to either deny guilt or apologize.
"I didn't think you'd mind Ms. Rose. I wouldn't be looking at you if I didn't think you're a beautiful woman." He replied, and Vanesa was almost shocked by his casually brazen tone.
"I suppose you think it's a compliment, hmm? Young man, there is a fine line between wanted and unwanted attention, and you should have the good sense to tell the difference! A girl your age might be flattered by such a crass display because she is a valid target for your affections. She might be interested in you as well, but would see your interest as complimentary even if she wasn't. A grown woman like myself is another matter entirely. The age difference between us is too great for any sort of flirtation, and as such your staring is unwelcome and quite frankly offensive."
"Well, why should age matter if we find each other attractive?" asked the colt who's sexual experiences so far had not indicated that the age gap is by any means unbridgeable.
"Don't be ridiculous. No healthy grown woman could find a boy your age sexually attractive..." she said, a bit more tersely and curtly than she'd intended. This colt's audacity was really getting to her, especially in her state. She'd felt the twinges earlier that night and knew that by now there would be an egg or two nestled deep inside and that her bothersome instincts would be urging her to find a male. She kept them firmly in check, of course, but the effort of doing so always made it harder to focus on her work.
"Well would you kiss me then?" Adam asked, and he could see the fins on the back of his teacher's jaw fan out as wide as they could, her slitted eyes open in shock as she faltered before replying.
"What in the world makes you think I would..."
"Just to prove a point..." the colt replied, still unfazed by the whole situation. "If you kiss me and there's nothing there it will prove you're right. I'll apologize and change the way I act around women..." he said.
"Fine..." Vanesa said, figuring that it would be worth it to show this brash young man that confidence and charm could only get him so far. After he embarrasses himself she'll have proven her point. After all, she doubted the boy had ever kissed a girl. And he thinks he'll change my mind just like that?
Still, it was a compromising situation. The school was largely empty, but she still led Adam to the back of the classroom where a passer-by was unlikely to catch a glimpse of them. She put one hand on the colt's shoulder as she bent her muzzle down to meet his, expecting nothing but an awkward kiss that would prove her right.
The colt surprised her by putting his hand on the back of her head, a gentle but possessive gesture that pressed her lips against his. The kiss was anything but awkward, and the basilisk was shocked at just how comfortable the boy was with this. She was surprised when his tongue found its way into her mouth, and even more when her own slipped out to play with the young stallions.
It all seemed surreal, something so bizarre that her mind couldn't accept it as anything more than sheer fantasy. The colt's other hand rose up between them and she could feel it undoing the buttons of her blouse with surprising ease considering he couldn't even see what he was doing. Once he'd reached the top, he slipped one hand under the white cloth, first palming and then groping one scaled breast through the fabric of her bra.
She couldn't believe how familiar this boy was with a woman's body, and how much her body was responding to what should have been awkward, nervous gropes. She felt her back arching, her chest pushing against the hand trying to cup her breast despite the fact that it was still a touch to small. Her hand had moved from the boy's shoulder at some point, her fingers now twined in his mane as she held him against her lips, hesitant to let him go.
By the time they broke their kiss her claim that Adam couldn't arouse her was broken. She was gasping for breath, her nipples stiff against the boy's palms, enough that even the fabric of her bra couldn't hide it. And while she still clung to the notion that she didn't find boys sexually attractive, she realized that Adam was an exception that proved the rule. And a look down was all she needed to see that the young equine found her equally appealing. What was left of Vanesa's mind was no longer bothering with whether or not she should go through with this, but merely how she'd do it.
"Don't say a word. We'll... just this once..." she whispered, and all it took was a nod from Adam for the once proud woman to get on all fours. It was undignified, but the rows of desks would serve to conceal them. She lifted her long, thick tail out of the way, knowing full well that the fan on the end of it would be fully flared by now, an instinctive reaction meant to attract and entice a mate. Not that Adam seemed to need enticing, or even guidance.
The boy had dropped his shorts and freed what Vanesa quickly realized would be the biggest shaft she'd ever taken. She could hear her heart beating in her ears as the colt behind her knelt and lifted her skirt out of the way, exposing her finely-scaled cheeks and the slit now concealed by nothing but a damp strip of cloth.
She felt him tug the fabric away from her moist lips, holding them aside as he pressed the bell-like tip of his cock against her sex. She knew this was a mistake, that the urges she'd kept in check while focusing on her career had overwhelmed her and that the smart thing to do would be to get up and leave this room right now, frustrated but with her dignity intact. But before she could seriously consider the notion of leaving the colt's cock was pushed against her opening, her body straining as the pressure increased until her pussy finally gave way and accepted the blunt head of her pubescent lover's cock.
Vanesa bit her lip to keep quiet, desperate not only to hide what she and Adam were doing from anyone chancing by, but also to hide just how intense this was for her from the cocky colt. She'd never been particularly adventurous and had found little to no time to date in recent years, but she suspected that even a more promiscuous woman would have found what she was currently taking a handful, so to speak.
It actually hurt - her walls spreading and her lips splayed as the equine appendage made slow but steady progress deeper into her. But the pain did little to dampen her arousal, her sex dripping even as it was impaled on Adam's throbbing length. The sensation of his medial ring pushing against her clit before it slipped inside was almost enough to make her climax, and the basilisk was shocked when a moment later she felt the tip bottom out inside her.
"Well Ms. Rose I may not be old enough for you, but I'm definitely big enough..." the colt said and Vanesa wanted to bristle at the tone but was afraid to open her mouth.
The sensation of that thick shaft being pulled almost all the way out was electric, and when Adam had once again sheathed himself inside her with one smooth stroke she could hear herself mewl as her heavy tail coiled itself gently around the boy. She felt like a prisoner of her body which wanted nothing more than to be rutted by this amazing member she was so lovingly wrapped around.
She could feel Adam pick up a rhythm, too practiced and smooth for a child his age. His hands roamed the smooth scales covering her ample behind as if he had every right to touch as he pleased, but she didn't say or do anything that might give him the impression that he couldn't. It felt demeaning to kneel like this in her own classroom while her student used her like a slut, but disgust didn't stop her from moving her rear back and forth, helping Adam slide out of her now dripping sex before she pushed back to meet his thrust, desperate to feel his cock claim every inch of her.
For his part, Adam couldn't help but grin at the sight of his teacher happily bouncing back to meet his humps, and the gentle way her thick tail was coiled around him, silently begging him to stay right here until his job was done. It was a fresh thrill to see how easy it was to get a stern woman like Ms. Rose to agree to something like this. Just a few minutes ago she'd been telling him off for staring at her, and now he was groping her ass and admiring the way it bounced as he pumped away between her legs.
He felt her pussy tighten around him, squeezing down and releasing him as the whimpering woman came after barely a minute of rutting. It was tempting to just ramp up his thrusts and finish up then and there, but he felt that he had something to prove to the buxom basilisk. He was also curious to find out where his limits were and how far he could go with a woman.
The thick reptilian tail was raised and it gave Adam a superb view of the tight looking little pucker nestled between those plump cheeks, and he couldn't help but smile at the way it twitched and winked as Ms. Rose continued her orgasm. He slid one of his hands closer and closer, pressing the tip of his hoof-nailed thumb before pushing it in and watching the ring stretch and flex around him.
Vanesa's eyes had gone wide as her rear was invaded, her cheeks coloring at the thought that the colt was brazenly fingering the spot she'd never allowed a man to touch. She should have said something, set some kind of line the boy couldn't cross, but she just wound up hanging her head, doing her best to keep herself from being pushed over as Adam's thrusts sped up.
She'd lost track of time and had no idea how long he'd ben rutting her, but she knew that she'd climaxed two more times before the monster pistoning in and out of her began to flare. With her face against the floor of the class-room and her ass still in the air, she tried feebly to protest, to beg the boy to pull out of her.
Nothing resembling words left her mouth as pain blossomed against her cervix. Adam had been a tight fit to begin with, and even after the rutting he'd given her Vanesa's reptilian sex was struggling with his growing flare. In the end she'd stayed like that and took every drop, to her own amazement. When the boy was done he pulled him thumb from her ass and his cock from her slit, letting her panties slip back into place and keep what felt like a pint of equine cum in her up-thrust rear. Through it all Vanesa said nothing, still trying to catch her breath as the colt politely said good-bye before leaving her face down in the empty classroom.
