Even though he didn’t know it, Allegro was a bit of an early bloomer, and having inherited the libido of both a ram and a stallion meant that his budding urges were hitting him hard, and with little to no warning. To make matters more complicated, his endowments were distinctly equine, and the bulge in his pants made him feel awkward at times even when it didn’t swell up and stiffen like it was doing now. He’d overheard some of the boys his age confiding that they were getting stiffies but that ‘rubbing them out’ solved the problem. Even now, Allegro gave his fleshy spire a few strokes, which only seemed to make the equine appendage grown harder and his mind foggier. He knew what would help, though. And he had the house to himself.
He walked by his sister’s bedroom with only a moment’s hesitation. Aria was very protective of her space and would freak out just to see him in her room without permission, let alone of she caught him doing what he intended to do. Their mom wouldn’t really bat an eye to discover one of her kids in her bedroom, but Al was still sure she’d freak if she actually caught him seeing to his problem. Just entering the ewe’s room had her son’s erection twitching as his nose caught his mother’s smell, mixed with the scents of her perfumes and cosmetics.
Walking with the silent tread of the guilty, Allegro made a straight line for his mom’s hamper, fishing around for a few seconds before his fingers brushed against his prize. A silky triangle, trimmed in lace, black except for the little patch of white fabric on the inside, the soft cottony part he knew was touching his mom’s sex. Allegro hadn’t had sex-ed classes yet, and his knowledge of sex was moistly made up of rumors collected by his equally clueless peers. But he did live alone with two females – a girl on the cusp of adulthood, and a mature woman still very much in her prime- and the exposure to these two was starting to stir things in him whenever he let his mind drift.
And while his mind drifted to his mother’s lush curves, her sweet voice and eyes that always seemed to gaze warmly at him, his hands were going through what were by now practiced motions, looping the elastic around his shaft and carefully arranging the panties so that the little white patch that had been pressed to his mother’s slit was now flat against the tip of his flare. He gave his shaft a stroke and felt the equine glans swell up against its silky restraints, a shuddering breath leaving his throat as he began to pump his stallionhood.
It just couldn’t compare to doing this in his room. It was somehow more intense doing in on his mom’s bed, feeling his cock touching the same thing the ewe’s slit had been rubbing up against. He knew he was doing it right when he got that strange feeling, sort of like he was running headlong downhill. He could hear himself breathing harder and harder, even though moving his hand up and down and weakly bucking his hips shouldn’t really get a fit young boy this winded. He imagined his mom wearing these panties, a matching bra cupping her ample chest.
Then he imagined her taking both of them off as he watched. Not that she ever did, of course, but he did catch a few glimpses of her getting out of a shower, flashes of her still steaming curves while the ewe busied herself towel-drying her thick hair with enough vigor to make some very eye-catching parts of her jiggle. He kept that image in his mind now, knowing that soon enough he’d feel that weird tension rising up even higher and finally breaking, after which his erection would go down and he could focus on his homework. For now though, every scrap of his adolescent attention was on the naked ewe in his mind’s eye.

Melody was always happy to come back home to her loving little family, particularly on a Friday. She always worked a little longer on the last day of the week to ensure her weekend staff could cope without her. Running a plant nursery was hard work, but the ewe found it immensely rewarding. She supposed that deep down she was a nurturing kind of person, and she often referred to the plants as ‘her quiet children’. Trying the door she realized that one or more of her noisy ones was back from school, even though they weren’t living up to the name.
In the crook of Melody’s arm was another little perk of her job – flowers that were already in full bloom didn’t really sell, so every Friday she filled up a little basket with several modest bouquets, and the ewe moved from vase to vase, changing withered flowers for new ones. The last one was lily-of-the-valley, and she’d saved the sprigs of tiny white bell-blossoms for her bedroom since she was quite partial to their scent. She was humming along softly as she climbed the stairs, swinging her door open only to have both the flowers and her jaw drop as she found her son on her bed with his shorts around his ankles stroking… himself. He’d apparently been too far into it to hear her come in, but her gasp must have been loud enough to snap him out of his fantasy.
“M-mom! This… I was just…” he stammered in a panic, trying to tug something off the tip of his erection, and almost hurting himself in the process judging by the way he was wincing.
“Shhhh honey, it’s okay. It’s… nothing I haven’t seen before…” she said, stretching the truth a little. Allegro had been bathing himself for years now, and as she sat down next to her panic-stricken son it dawned on her that those had been very… formative years. She wasn’t naïve, of course. The moment he was born it was clear that he’d have one hint of his equine parentage. And as her little baby hit his growth spurt a little early she’d made sure to buy him pants with a little extra room in front, so that he wouldn’t have problems with any… bulging down there.
She considered leaving the room and letting her son compose himself, but it felt like she’d be turning his back on him when he was vulnerable. She was sitting next to him before she knew it, hand wrapped around the panicky ram’s shoulders as she cooed sweetly to try and calm him. For all his size and athleticism, Allegro was a fairly introverted child, and through his life she’d done her best to coax him out of his shell. She wanted to make sure this was an awkward moment for her boy, not a scaring one.
“Here sweetie, let me help… oh!” she said, managing to peel the blushing ram’s hands away from his flare only to see what he’d been so desperately hiding from her.  It didn’t take her more than a glance to identify the scrap of silky black fabric, tangled and straining around the narrow part of her boy’s shaft just behind the mushroom-like tip. Her boy’s glans had flared up, which was why he’d been having trouble pulling the panties off his enlarged tip. 
“I… I was trying to do my homework, but it…. got like this and… and I know I shouldn’t have gone through your things, but this… this helps. A-are you angry?”
“No honey, it’s… it’s natural. You’re just growing up and… and growing boys have needs…” she said, which was true. But she also couldn’t help but wonder what had been going through the young ram’s mind before she interrupted him. Was he imagining one of the girls from school, maybe a young teacher… or was actually thinking about her?
It wasn’t a healthy thought for a mother to have while staring at her son’s erection. Her eyes were fixed and the stretch of silky fabric stretched across her boy’s flare and the noticeably wet sheen to it. Her thighs rubbed together as she imagined herself in her undies as the hard length of equine muscle rubbed up against it. Urges that she was sure she’d successfully bottled up years ago were now bubbling up, reminding her in an unsubtle way that even though she wasn’t going through puberty she still had the same needs her little Al did.
Even though a mother of two, Melody was still quite young. She got married right out of high school and had given birth to Aria when she was twenty. Unfortunately she’d had the misfortune of becoming a widow at nineteen. Friends and family insisted she should get back to dating, find someone new, and three years later she did just that – falling for a very charming young stallion who’d given her Allegro but ran out on her the moment he found out a baby was on the way. After that, she didn’t feel like risking heartbreak again, not with two lambs who needed her. 
With her savings and some help from her family she’d moved out into this quiet little town just outside of Ohla, a little slice of heaven out in the mountains that had proven to be a wonderful place to raise her family. At thirty-six she still had needs, but she’d always been able to sate them herself whenever she could find some alone-time. But now that she was sitting next to an aroused and very well-endowed male, twelve years of abstinence were hitting her harder than she imagined.
“So you… haven’t finished?” she asked, noticing that her boy’s cock was still fully hard.
“N-no? It… kinda takes a while…” Allegro answered a little awkwardly, possibly surprised by Melody’s tone. She doubted he’d ever heard a girl use that tone of voice on him, least of all his own mother.
“Would you like me to help you?” Mel asked. It was surreal, she couldn’t believe what she was suggesting, but as her thighs rubbed she knew full well what she wanted.
“H-help?” Allegro asked, voice quivering as it conveyed the awe plastered on his wide-eyed face. If he’d turned her down, if he’d shown any sign of being uncomfortable with this Mel knew she would have come to her senses and stopped this. But as she got up there was no mistaking the hunger in her boy’s eyes as they glued themselves to her body, or the way his eyes bulged as she knelt down between his legs.
With a gentle touch Melody untangled her panties from around her boy’s shaft, the fabric that had been stretched across his flare so soaked by now that she almost peeled them off. She gently brushed her hand up along the underside of the young ram’s erection, smiling as even that little caress made her boy gasp and dig his fingers into the bed sheets. After more than a decade her hand wrapped around a male, her own heart beating a little faster as she felt a familiar thrill of something hard yet silky flexing and throbbing in her grip.
She gave the shaft a few teasing strokes, a loose grip when sliding down and a tighter one when sliding up, probably a bit of overkill for a barely pubescent boy who’d never even felt someone else touch him like this. Mel’s other hand settled on the smooth bulge under her son’s erection. She remembered Allegro’s father having a heavier one that swung low and full, the sort of thing you’d expect to see swinging between a stud’s legs. The two testes her son was sporting looked and felt thrillingly firm, but they were still quite snug. They were cute, they seemed very sensitive, but Mel wasn’t sure if they were still just for show. She did feel her tail twitch and the panties she was wearing grow a little messier at the thought. Not only was it cute to consider that even sporting such an impressive coltish erection her boy could still only have dry orgasms, but the idea that he was still ‘safe’ was fueling some very un-motherly thoughts.
She was sure she’d get her answer soon enough. If her boy wound up squirting, well they would end this little game there with his little ‘problem’ taken care of. If he didn’t... well, Melody wouldn’t pressure him into anything, but she knew it would be up to him to leave this bedroom. If he chose to stay then they would take this little game just a little further. For now though, it was a thrill for Melody just to watch her adorable little lamb almost squirming with his touch on the edge of the bed, the fine runner’s muscles along his legs twitching as she stroked and fondled his pubescent shaft.
It was probably overkill, but the ewe was horned up herself and couldn’t resist getting a taste. She started with a kiss in the middle of her son’s flared tip, her eyes closed even though she could feel her son’s gaze on her. She planted a few more tender kisses on the boy’s glans before sticking her tongue out and running it along the rim, drawing a gasp from Allegro who was doing a good job of fighting the urge to buck his hips.
Melody’s tongue danced along her son’s twitching length, her muzzle trailing down until she was nuzzling that snug looking sack of his and finally running back up along the underside. When she reached his tip she planted her lips against it once again but this time she parted them and pushed her muzzle down, looking up and trying not to smile around her mouthful at her son’s expression. She’d remembered enjoying the taste of a stallion well enough, but Allegro was still young and rather than the sharp thrilling musk of a true stud he had a cleaner scent, something that stirred her womanly needs and motherly instincts.
He was also a much easier fit, since the ewe had managed to get her lips all the way down to his crotch without choking or gagging. She moaned softly as she pulled her muzzle off, feeling the hot, hard flesh run across her tongue as her boy moaned. She’d managed to do it a few more times before he the length of colt-cock in her muzzle began to twitch in a very telling way. Melody quickly pulled her mouth off her son and wrapped her hands around the trembling shaft, eyes trained on the flare swelling up before her eyes. She didn’t want to miss this – if what came out was even a little milky this would be as far as their little game went, but if it was clear…
Her hands stroked furiously as she watched the trumpet-like glans grow, her slit quivering at the sight of it. She remembered what it felt like to have it happen deep inside her, to feel that tiny little tube even now sticking out brush against her cervix. A perfect mechanism to ensure that her body would take everything a stallion could give it, a surge of seed so powerful that it would fill every nook and cranny of a nubile young body, ensuring that even though she wasn’t in heat her body would be carrying equine sperm around until she was fertile. This was something she’d only realized after conceiving Allegro, which was why she had to be sure…
Melody was biting her lip by the time her little ram finally started to buck into her grip, his urethra jutting out but producing nothing more than a few weak squirts of clear liquid. So there she was – horny enough that she could feel her panties clinging to her wet sex, kneeling in front of a beautiful young male who loved her, would never abandon her… and couldn’t get her pregnant. She watched her son climb down from his peak, that boyish chest heaving as little twitches and tremors ran along the musculature that was still more graceful than manly. Melody knew that she’d lost the last of her inhibitions. This would only stop if Allegro stopped it. The coltish cock in her grip was slowly going soft, but she knew that was no obstacle.
She rose without a word, smiling at the young ram gazing adoringly up at her, the still bleary eyes going wide when she pulled the airy dress she was wearing over her head. She kept smiling at her boy as she reached back to undo the clasp of the bra, catching the way his ears swiveled when the elastic went slack, the cups clinging to her breasts before she shrugged the garment off. Melody’s peach-pink ruffle came down in a sort of natural plunging neckline – a wedge of cloud-soft fleece that denied curious eyes a glimpse of her cleavage but that tended to really accentuate her bust when she revealed it.
Mel had heard that one of the advantages to an early pregnancy was that your body fills out when it’s still young enough to firm up afterward. Her figure had the generous curves of a woman who was twice a mother, but every curve looked perfectly supple, the sort that bounced rather than wobbled. Her breasts were full and round, and without being vain Melody would have to admit she was quite proud of them. They drew a glance very now and again, since even a thick sweater couldn’t mask them, but it had been a while since her breasts had a captive audience like this.
Allegro was still reeling from that amazing feeling of release that always followed one of his stroking-sessions. Except those usually ended with him tossing a pair of his moms (or on a few occasions Aria’s) panties back in the hamper. And it definitely felt better having someone else do it! There had been a moment when his mom took his stiffy in her mouth that he felt like he was going to faint, like something he couldn’t even describe was about to happen, but the feeling tapered off suddenly and he wound up just going through that strange grunting/panting stuff that meant he was done.
And before he knew it his mom was standing before him and shrugging off her bra. He’d had a crush on both her and Aria for a while now, but he’d kept it as his little secret since they were his mother and sister and nothing would ever happen. Now his mother was pulling her panties down, her breasts swaying as she leaned forward to slide them down and expose the pink patch of wet skin between her plump thighs. Holding his gaze and that peculiar smile she sat down on the bed next to him before laying back and sprawling out on the sheets. She put her arms above her head and stretched in front of him, throwing out the chest her pillowy breasts were now spread over.
“C’mere sweetie… you’re not too old to cuddle with mommy, are you?” she crooned what would have been an innocent invitation if she wasn’t posing naked with a wet patch between her legs.
In the state Al was in, it might as well have been a command. He was in bed alongside her before he knew it, his mother’s arms wrapping around him and directing his face to her lush chest. Allegro pushed his face into the dense fluff at the top, drawing in the scent of his mother’s fur and feeling his head swim from the sweet, gentle musk of the voluptuous ewe. He felt fingers being run through his long hair, scratching at the base of his short horns and finally guiding his mouth towards a pale-furred mound.
He looked up into his mother’s eyes and the look she gave him told the confused young ram to go ahead. His lips brushed against the soft pink areolae, the lingering sigh of the ewe under him spurring him to push his muzzle into the pliant mound and to draw the nipple into his mouth. His mother writhed against him, holding him against her breast as he began to kiss, suckle and lick. One hand rose to cup the mound he was nuzzled up against while his mom guided the other. He squeezed gently, encouraged by the noises she was making, and while he pretend-nursed from one of his mother’s tits he kneaded the other one, all to a steady stream of eager sighs and soft moans.
He was aware that his shaft had gone soft but hadn’t gone back up inside his sheath the way it usually did. It was just pressed between them, resting against his mom’s hip until the ewe noticed it and slid a hand down. He’d never touched himself when he wasn’t hard – in his view the only reason for doing it was to get rid of an embarrassing erection in the first place. But it felt kind of nice the way his mom was playing with his tumescent cock – firm but gentle squeezes, playful tugs, the feel of a soft palm and velvety fur. At times she’d just hold him gently and Allegro would find his hips were moving, nudging the once again firm shaft against his mother’s body.
“Sweetie, do you want to make mommy feel good?” Melody asked, ears catching to soft pop of her nipple slipping from her little ram’s mouth. She knew the answer before he’d murmured it, just by the way those wide twinkly eyes were looking up at her.
She shifted a little and helped her boy up, knowing that even though he’d be the one on top she’d have to make this happen. He’d hit an early growth-spurt, and the coltish cock resting on her lower belly was big enough to make the grown ewe bite her lip in anticipation, but it was obvious how adorable clueless her little ram was. He did seem to know what was supposed to go where, bracing his hands as he slid his hips back, the flared tip of his cock trailing down along her mound until she felt it drop and settle against her slit.
The sensation of wet, silk-smooth lips against his tip made the boy buck instinctively, the equine shaft bowing for a second before the glans slipped and the whole thing angled up. She tried not to giggle at the intense look of concentration on her boys face as he lined himself up. He was to loathe to take his eyes off hers even to see what he was doing, and Mel couldn’t blame him. She certainly didn’t want to miss seeing her little lover’s face in the instant he gave her his virginity, and could appreciate that he wanted to watch hers as he took her as a man takes a woman.
His next thrust was a little closer to the mark, but still wound up missing, and when the next one slipped down instead of up Melody realized she better help her boy before she wound up losing a certain virginity herself. She slid a hand down and opened up her folds, cupping her son’s tip and guiding it until they could both feel the kiss of his flare against the inner folds of her sex. Allegro pushed again but this time she felt her labia part around him, the blunt tip pushing in with a wet little squelch their shared gasp failed to mask.
Driven by instinct, her little ram pushed in as deep as he could go, coming to a shuddering stop only when his hips were pressed into her crotch. He lay atop her with his head resting on her breasts, stunned by the sensation of wet warmth suddenly holding him tight. Mel caressed his hair and held him close, knowing he needed a moment to compose himself. And if she was being honest, so did she. Her boy felt bigger than he looked, and after twelve-years of nothing but her fingers in there her nubile body was responding in a very unsubtle way to once again having a male where he was most needed.
She was sure that if she hadn’t given her boy an orgasm minutes before he wouldn’t have lasted more than that first thrust. She could feel the muscles along her belly twitch and dance, and the ones deeper down clench up, molding her glistening walls even more firmly against her son’s stallionhood. Each time she did that the hard length in her felt even thicker, the pulse of it more pronounced as for the first time in a long time she felt her son’s heartbeat inside her. What was laying atop her might have been her adorable little twelve-year-old boy but she felt like she had a stallion between her legs, hard and throbbing as he stretched her out like a male should.
After a while she noticed Allegro was grinding against her, barely sliding out at all but still causing his equine erection to shift and stir in the snugness of her sex. She kissed the top of his heat to encourage him, lifting her legs to give her young lover as much access to her. With exquisite slowness the grinding motion of her son turned to very shallow thrusting, the equine shaft slipping out just enough for her to feel it slide along the snug tunnel clinging to it. A few more strokes and he was pulling enough out for his medial ring to leave Mel’s steamy sex, and the first time that ridge pushed back in she found herself locking her legs around the panting child making a woman out of her and a stud out of himself.
Her boy’s eyes looked glazed, occasionally meeting hers but seeming to drift more and more to the pale-furred breasts that were starting to bounce a little as he started thrusting harder and faster, still gentle and loving but leaving little doubt in Melody’s mind that she would wind up cumming around her son’s erection at least once by the time he was done with her. His next thrust caught her off guard – a sharp lunge that had her breasts bouncing and her muzzle opening in a cry no boy barely into puberty should have been able to coax from her. A sound that had her son’s big ears swiveling as some part of him recognized it for what it was…
What happened next took the ewe by surprise, albeit a very pleasant one. She felt her boy’s body shift a little before he repeated the same powerful thrust, and then again, and again until he was humping into her with a very steady and very vigorous rhythm. He was going at it like a proper stud, even though his head only came far enough to wedge between her supple mounds. But he did look adorable with his face smooshed between her breasts, his nostrils flaring as every huff and puff made the ruffle of rosy fur billow up.
Deep down she knew almost every mother out there would be aghast to see her on her back and moaning while her tween son plowed into her, but to the ewe that had spent so long without any touch but her own this felt so right. She hadn’t actually gone out to seduce her son, and she had done nothing more than to offer her body to a male who she knew deserved it. Her darling little child who was normally so shy he needed coaxing to join in any social situation hadn’t even hesitated to mount her and give her his virginity.
 Through her moans and her son’s grunts Mel’s ears picked up a new sound, a soft tinkle just on the edge of hearing. Looking down her muzzle she realized that her boy was rutting into her hard enough to make the little bell-pendant she wore ring. It wasn’t the brassy cling-clang of an actual sheep-bell, but it was testament to the force her little ram was putting into his first time. She went to all of Allegro’s track meets so she knew that her lamb had impressive stamina for a boy his age, but she’d never really been in the position to really appreciate just how much energy was packed away in that svelte young body. As the bell continued its tinkly little chime, the ewe held her little lover close and tight as she savored the hammering little Allegro was giving her…
*******
“Ughhhhh, you’ve got to be kidding me!” Aria groaned, a hand on the doorknob as she re-read the message on her phone. With a final huff she opened the door and let herself in before thumbing through her contact list.
It was Friday and she’d been looking forward to her date with Martin, a rather cute and lanky Dalmatian that she’d been dating for… well, just long enough for a serious date. She’d been fairly certain that at some point tonight she’d wind up counting the cute dog’s spots, but the basketball team had an away game tomorrow and the coach insisted they all had to be in bed early. Is he going to come around and tuck you guys in? Read you a bed-time story? she thought as she sent messages out to her female friends. More reliable but less stimulating for a sixteen year old girl who’s body had finally filled out enough to get her masculine attention. She definitely wasn’t going to let Martin ruin her Friday night, and if fate should have it that she met someone hunkier than the Dalmatian, she supposed it would only serve him right for placing an orange ball over her.
A floppy ear swiveled as the pings of incoming messages were overshadowed by the familiar sound from upstairs. Is that… was her little brother jumping up and down on his bed? She shook her head and smiled at the idea that the lovable little dork was actually still doing that at his age. Then the sudden idea popped into her mind that he might in fact be jumping on her bed in the room he was expressly forbidden from entering without her permission. Indignant rage propelled the young ewe up the stairs, but she never made it to her room.
Her ears had been right when they heard a bed straining, but now there were other noises that painted a different picture. It was coming from her mother’s room, which seemed appropriate since she could hear her mother’s voice making very explicit noises. She couldn’t believe it though – mom hadn’t brought a man over… ever! The last time she’d been with one was when she got pregnant with…
Allegro!
The young ewe’s hand flew to cover her muzzle and stifle a cry of surprise once she spotted her little brother on top of his own mother. The door was open a crack, and the two would have seen her peeking if they weren’t completely lost to the world at this point. Her mother was clinging to the firm young body ramming into her with more strength that she’d have guessed her little brother could muster. His little tail was flagged as his boyish butt rose and fell, the cheeks tensing as he rutted the woman under him.
Aria stood rooted in place, feeling her pulse quicken as her own body responded to the lewd spectacle taking place in front of her. She couldn’t really see her brother’s cock from her vantage point, but she’d seen him leaving the shower a first time and knew that the soft-spoken lamb had a stallion’s endowments. She’d never seen him hard though, so she had no idea how big he got… but mom really be making those noises if he wasn’t… gifted? Her imagination running wild, Aria almost didn’t notice her hand slipping from her mouth, sliding down her trim young body and into her panties…
*******
“Mom… I… I think…” Allegro panted, and Melody didn’t need any more explanation than that.
The ewe could feel her boy’s flare moving around inside her, just a little bit of extra stretching deep inside her as the rim of the equine tip rubbed against the walls of her sex. She’d been holding back, for how long she had no idea. Al’s stamina was impressive to say the least, but even her little track-star was nearing the end of his rope. Her legs tightened up behind him as she pulled his face into her cleavage, her ears flicking as she prepared to feel her little ram climax inside her.
“Shhhh, it’s okay baby, just keep going… Nhhhh, like that…” she cooed, stroking his hair as she felt the growing flare throb with every beat of his heart.
She felt the urethra just out, the tiny tube poking her cervix before Al gave one final thrust and instinctively held himself still. She felt her hold on her own libido break and take her mind along with it, her own high moan echoing in her ears as her body began to draw out what she knew for a fact her little lover couldn’t give her. The contractions of her sex were more than Allegro could handle, and with a final groan she felt the powerful flexes of his cock, the throb of his flare. So far gone was she that she was almost sure she felt a spurt from that little jutting tip, a surge of cum destined to flood her womb by the swollen flare plugging her.
Wetness, warmth… so real, but more than likely mostly her own. She remembered the cute trickle of thin pre her boy had managed when she’d stroked him to completion. Anything he was giving her now was probably less than that as those cute pubescent balls pulsed in their snug little sack. It must be because of the way he’d rutted her. He’d taken her like a stallion fully grown, and now she was imagining he was having a stallion’s climax, that every flex of that girthy shaft hilted in her was pumping out a fresh rope of thick, pearly cum.
Allegro spent a minute or so with his head pillowed on her breasts, shuffling off her only when his cock had started to soften within Mel’s still quivering honeypot. She first started to suspect something was amiss when the passage of the flare seemed to pull something along, the same heat that she’d felt deep inside her and attributed to her imagination. When the still flared glans popped out of her freshly rutted folds the sound was unmistakably messy, more than twelve years of abstinence could account for.
Her boy’s cock was glistening, but there was something disturbingly milky to it, and once she looked down she realized why Allegro was staring at her sex like that. Her labia were blushing a very pretty pink and still noticeably gaped, enough to let a thin, thick stream trickle from her depths. She watched in shock as what she knew was just the excess leave her body, warm, pearly goo running down her winking pucker to soak into her tail. She stood frozen while her son’s seed drained from her sex, her mind replaying the sequence of events that ended with Allegro’s father walking out on a hopeful young ewe who’d dared to fall in love again.
“Mom… are you okay?” Allegro asked, feeling at least some of her distress. One look at his concerned face was enough to bring a smile to Melody’s. She’s not a naïve girl anymore, nor was this a male who would ever abandon her. 
The quiet, tender moment was broken when the door to Melody's bedroom flew open and a figure that seemed to have made the mistake of leaning against it almost tumbled in head-first. Aria had gotten more than a little carried away, as evidenced by the skirt and panties hanging off one hoof and the cramping hand stuck between her slender thighs. She had almost climaxed watching her baby brother examining the cream pie he'd left in their mom when her left leg buckled and threw her off balance.
"Aria! Wha... how long have you..." Melody gasped, looking ridiculous as she covered her breasts from her teen daughter's gaze.
"Long enough. Well, no, not exactly..." she said, looking down at the mess she'd made of her hand, all without actually achieving release. To horned up to care, the young ewe walked into the room where she wasn't invited, but where she hoped she would find welcome. The way Allegro was looking at her was certainly promising.
"Honey I... I was just helping your brother relax and... and things got out of hand." the ewe said.
"It's okay mom, I'm not gonna tell anyone..." she said, walking up to the pair and hinting with her tone that there might be a price for her silence. "Our little secret. Right li'l bro?" she said, coming up behind a very confused looking Allegro and letting her hands run from his shoulders down his chest. Innocent enough if one didn't count the way her eyes drank in the sight of his cock, still glistening with his own spunk and their mom's juices. Nor did she miss the way the snake-like length gave the tiniest twitch as her palms slid across Al's nipples.
"M-mom?" he asked, confused by the affection his sister was showing him.
"Only if you want to sweetie..." Melody said, knowing that there was no way to going back their old family dynamic. They'd work something out, but in the meanwhile she was still the adult around here and would make sure her kids knew it.
In response Aria drew away and removed her top and bra while her brother watched. While her figure wasn't as generous as her mothers, the young ewe posing for her little half-brother was undeniably beautiful. Her breasts were not full but they were firm and high, and Aria was brazenly thrusting them out, her trim belly and shapely legs completing the image of a young beauty not yet in full bloom. Allegro definitely seemed to like what he was seeing, and Aria moved in to capitalize on that interest. To her credit she was being sensible to her brother’s shy nature and tender years, sitting close enough to him for her leg to touch his, running a hand through his hair, along the line of his jaw until she had a finger under his chin, tilting his muzzle up.
The kiss was cute, Aria had to admit, and there was a thrill to not only kissing her brother like this but also a boy so much younger than her. She reached out for Al's hand, grasping his wrist and gently guiding it to her breast. She felt it tremble for a moment before the little ram started to squeeze, her nipple growing stiff against the softness of his palm. With her brother’s hands full she figured she was due a grope, and when she reached his crotch it was her turn to get trembly fingers. Even soft as it was, her little bro's cock felt thrillingly meaty in her hand, warm, wet and heavier than anything she'd gotten her paws on so far. A little lower down she could feel his sack, snug, firm and seemingly too small to be responsible for the mess she'd seen leaking out of their mom.
Her polishing had paid off, and the fleshy snake in her hand had turned into a firm length of colt-cock, thick and with veins and ridges that looked like they could really make a girl's tail twitch. She broke her kiss with Allegro and while the boy was still catching his breath she was laying on the bed with her face poised over his erection. While her little bro's balls looked adorable, the spire rising above the snug sack was definitely bigger than anything Aria had gotten her hands on so far. She had to open her jaws pretty wide just to make sure her teeth were out of the way as she pushed her mouth down along Al's stallionhood. She couldn't even take everything he had without gagging, and she wondered briefly if their mother had even managed to take all of her son. She managed to keep it up for a minute or so before her own needs pushed her to skimp on the foreplay.
"Bet you're tired after that performance, huh?" she asked her brother, referring to the wild rutting he'd given the buxom ewe kneeling on the bed beside them. "Don't worry, just lie down and let your big sis take care of you..."
The awe-struck boy gave no protest and soon enough Aria was straddling his hips and aiming that blunt tip at her snug young pussy. She spread herself open and pressed the tip to her petals, gasping as she felt the mixture of soft, silky flesh and the thrilling hardness underneath. If someone that morning had told her that she'd be taking her little brother’s cock up her teen cunny she would have balked at the idea. And if they had suggested she'd be straining to take it she would have laughed out loud. 
Even so, it took some effort and finally a bit of brute force to get the equine love-muscle inside her. She winced as her brother's cock stretched her out, even though it was only just the tip stuck between he splayed folds. If Aria wasn't as horned up as she was she might have wussed out, but strain as it might there was no mistaking the way her soaked slit welcomed the equine glans. She swiveled her hips from side to side a little even as she lowered them, making exquisitely slow progress down her brother’s shaft. Aria felt her ears flick as he filled her, her pussy gripping him tight enough for her to feel every vein, ridge, every twitch and throb as inches disappeared into her trembling young body. Soon enough she could feel the medial ring pressed snug against her clit, and another buck of her hips had her folds stretching just a little further as they let the ridge slip inside.
By the time she'd taken all of him she was panting, her flat tummy quivering and her nipples sticking out of the gently curved breasts gracing her heaving chest. Her little brother was definitely not little where it counted, and Aria actually had to take a little while just to get used to having him inside her. When she began moving it was mostly just back and forth, grinding her slit against his crotch as that girthy spire rubbed all the right places inside her. Her back flexed and arched in time to the movements of her hips, and little by little she was starting to slide herself off her little stud, moaning softly every time she drove down and took him inside her again. She became aware of a warm breath on the back of her neck just before arms slid around her waist and a pair of soft, lush breasts pressed against her back. 
Her mother's presence felt strangely natural, possibly because the young ewe realized that they would be sharing their new male. She felt the older ewe move along with her, slow and sensuous as Melody nuzzled her daughter's neck, her hands rubbing the young ewe's belly as if she was trying to stroke the stallionhood making it bulge out faintly. She had to admit it was intensely hot feeling a thick, hard stallion inside her and looking down to see what was still just a very handsome boy. Well-built for twelve, her brother was still smaller than the guys she dated, although it was clear he had them beat where it really counted.
Even with her young sex leaking around the invading length her brother was a snug fit, and she could see the way her folds clung to the equine erection whenever she raised her hips off it. Her strokes had gotten long but her plunges were becoming more and more forceful as her needs mounted and drove her past the point of caution. She leaned back into her mother and the older ewe's pillowy chest, her skinny hips rising and falling faster and faster as she bounced her way to climax. She felt her mother's hands slide up until they were cupping her breasts, the older ewe's fingers finding her daughter’s stiff nipples as they fastened around the hard pink nubs. The ewe's last trace of self-control was gone at that point and she was bouncing wildly on her brother’s lap, her cries rising in pitch and volume until with a final plunge they broke.
Allegro had grown even bigger inside her and she could tell both by the grimace on his cute face and the warm wetness blossoming inside her that her little brother was breeding her, or would be if she was anywhere close to her heat. She gyrated on his crotch, savoring the flood of pubescent seed filling her while her mom tweaked her sensitive nipples. Her brother was still drooling a bit of cum when she pulled herself off, giving the softening equine length a final suckle before the spent shaft slid back into its sheath.
"Right, I think we could all do with a nap after that..." Melody said, and her children cuddled up to her in silent assent. "And when we wake up we'll need to have a little talk. Aria, you and I will need to get on birth control, and we'll need to tech your brother how to use condoms..." she said, reminding them that she was still their mom, even though it looked like their relationship was about to get a lot more interesting...
