Familial Fraternisation

“Ugh…” Babs quietly grunted, rolling her eyes at the unfolding festivities.

She’d been immeasurably pleased to be finished with school, and she’d been happy enough to accept Apple Bloom’s invitation for a visit, but she was not thrilled with the huge hootenanny that her cousin had surprised her with. Her round-trip ticket meant she’d be unable to get home for three full days, and leaving the party would be extraordinarily rude, so she found herself stuck. Resting with her back against a wall, well away from the mass of dancing, chatting, and socializing ponies, she leisurely sipped her beer.

It sure as hell seemed like most of Ponyville was in attendance, with the interior of the Apple family farm positively brimming with ponies of all ages. Be damned if she knew why everyone in town had shown up for a graduation get together, but her best guess was that most of the folks typically looked for reasons to have a celebration. As she scanned the cavernous room, over the throng of smiling, jubilant faces, her eyes settled on an anomaly.

Standing at the far side of the chamber, seemingly as disinterested as herself, a titanic figure lingered. Wearing a pair of overalls, with a sizable portion of his broad, crimson chest visible, the golden maned stallion’s emerald gaze rested on her - that was, until he noticed her looking in his direction. With little else to do, having arrived just before the festivities began, she slowly circumvented the teeming mass of partygoers to say hello to her older cousin.

Though it took her a few minutes to make her way over to him, having been stopped no fewer than a half-dozen times for hellos or well-wishes, she eventually made her way over to the stoic colossus. She was big by most standards, standing taller than the average mare by a few inches, but she felt puny compared to Big Macintosh. Towering over her, with his barely covered pecs resting squarely at her eye level, he nodded a greeting.

“How’s it goin, Mac?” she asked, playfully elbowing his arm. “Life on the farm been treating ya alright?”

“Eeeyup,” he flatly responded, looking her from top to bottom.

Though he may have been bearing his trademark, placid expression, he had to admit that he was a bit stunned by how much Babs had grown. What used to be a runty, squat filly had blossomed into a tall, curvacious, and impressively built mare. It was common knowledge that earth ponies, like herself, tended to have a robust physique, yet he could never have fathomed just how attractive she’d become with age.

“Surprised you’re not out there having fun,” she began, subtly motioning towards the crowd. “Not much of a party animal?”

Mac slowly swung his head from side to side, as he raised his bottle to his lips. “Nnnnope.”

“Yeah, same,” she murmured, looking down at the floor.

Resting herself beside him, possibly the only other creature within miles who didn’t care to be there, she disinterestedly looked him over. If she had to guess, he’d probably done most of the heavy lifting, both literally and figuratively, in preparing for the hoedown. In a very real way, he was the backbone of the farm and one of the strongest, biggest stallions she’d ever met - having said that, he was also one of the quietest.

She never got a good explanation as to why he’d always been so tacit, but she wasn’t about to complain. Tall, silent, and almost painfully handsome, she was shocked that some mare hadn’t come along and scooped him up off his massive feet - at least, she hadn’t heard about any women making a move on him. Lost to her thoughts, apathetically inspecting his well-fitting jeans, she noticed an odd swell.

As Mac took a well-deserved swig from his beer, quietly wondering if Babs was as displeased with the party as she seemed, he looked down and froze. Given his height, he had a bird’s-eye view of her generous, ochre cleavage, but that wasn’t what unsettled him. Be darned if he could explain why, but it sure as heck looked like his cousin was staring dead at his crotch.

“So - uh -” Babs fumbled, rubbing the back of her neck, “you…”

As she looked up, seeing him peering down at her, she went rigid. Being caught checking someone out was embarrassing enough, but being caught ogling a family member was definitely as awkward as it could get. Her mind raced, trying and failing to think of something - anything to say to excuse herself, and she latched on the first ridiculous idea that came to mind.

“Heh - ” she forcefully chuckled, reaching over and brazenly fondling his groin, “I’m guessing you stuffed something in there to…” She stopped dead, feeling the unmistakable imprint and warmth of flesh against her palm.

Her eyes sailed to his package in disbelief, as her mouth went dry. Either Mac was packing a third leg or she’d just unintentionally groped an almost impossibly huge dick. Instinctively retracting her hand, feeling her blush deepen, she anxiously gulped. What she’d meant to be a joke, poking fun at the stallion for stuffing his undies, had ended up being anything but.

“T...that’s just something you put in your pants, right?” she timidly asked, unable to keep herself from sneaking glances at his denim veiled loins.

Mac opened his mouth to reply, but no words escaped him. For some inexplicable reason, his cousin - a cousin he’d been casually admiring for the last hour or two, had just copped a feel of his goods. Lazily shaking his head, praying that his growing excitement wouldn’t be too noticeable, he shakily pointed towards a nearby cooler.

“Yeah...yeah, that’s a good idea,” Babs croaked, feeling suddenly parched. “I’ll go get us another beer.”

Watching the mare trot over to the ice chest, realizing he’d been holding his breath, Mac exhaled. Unfortunately for him, his relief was perilously short lived. As the young woman bent over at the waist, with her backside leveled squarely at him, he only then noticed just how short her shorts were. As the garment rode up her thighs, practically disappearing into the cleft of her sublimely plump ass, he felt his stallionhood twitch.

Prying his eyes off his cousin’s backside, it was all he could do to look away and pray he didn’t get too excited. Having gone through a very, very lengthy dry-spell, the sight of a fine booty, even one belonging to a distant family member, was enough to get him a bit worked up. Trying and failing to distract himself, noticing her straighten with two bottles in her hands, he anxiously shifted.

As Babs walked back to the giant stud, she noticed a few things. First and foremost, the big lug seemed to be sweating a bit - secondly, and more alarmingly, the bulge in his pants had nearly doubled in size. Drawing nearer, peeking at the imprint of could only be his cock, she was stricken with an insane idea. There was no way he’d been turned on by her, had he?

The notion that Mac was aroused by her was novel, bringing a predatory smirk to her lips. Though she’d matured a bit over the years, abandoning most of her bullying ways, the temptation to toy with others had never left her - as such, she saw no harm in screwing with the reserved stud. If he found her attractive, and if she was to blame for his growing erection, he was about to be in for a big surprise.

“Here ya go, Champ,” she chirped, strolling to his side and presenting one of the perspiring bottles. “Sweet Celestia, it is way too hot in here,” she groused, fanning her top and revealing the upper portion of her breasts. “You know anywhere we could cool off?”

Looking down at her, seeing her pull her collar down just far enough to show she wasn’t wearing a bra, Mac’s heart skipped a beat. He wasn’t sure what had gotten into her, but she did make a point; the party was stiflingly warm. As the ache in his loins intensified, with his hardening stallionhood struggling against his pant leg, he lifted a hand and pointed towards the ceiling.

Babs craned her head, peering at the ceiling. “There a loft up there?”

“E...eeyup,” he sputtered, hoping she wasn’t about to ask him to…

“Lead the way, Chief, because I am sweltering,” she snickered.

Mac could’ve kicked himself, but there was little he could do now. Seeing as how it was her party, and she’d traveled all the way from Manehattan to visit, he couldn’t just tell her off! Silently cursing his rotten luck, he resignedly turned and led her towards a stairway in one of the storage rooms.

As Babs walked along behind him, she couldn’t help but admire his figure. Every part of him, from his wide shoulders to his sculpted backside was perfect, almost too perfect - heck, had he wanted, he could have been one hell of a model! Gazing at his rump, trailing him to a small backroom, she followed him up a flight of stairs and into a dimly lit, expansive loft.

“I didn’t even know this was up here,” she remarked, taking in the area.

Just as big as the first floor, but lacking the heat and crowd, the second story was almost empty. Outside of a few pieces of dusty furniture, stacks of apple boxes, and a handful of support beams, they had the place all to themselves, which suited her perfectly. Without any warning whatsoever, strategically blocking the exit, she grabbed her collar, lifted her arms, and pulled her shirt up and over her head.

“Much better,” she loudly sighed, swaying her bare bosoms from side to side.

Mac had assumed she’d just wanted some air, or possibly a bit of quiet, but he’d been dead wrong. Turning towards her, hearing her comment, his jaw hit the floor. Completely topless, with her sweat-streaked breasts glistening in the cool light, his cousin smiled over at him.

As amusing as Mac’s reaction was, Babs wasn’t done yet - not by a long shot. “Well then,” she purred, strutting over to the petrified stallion, “since we have a bit of privacy, how about you prove that you didn’t cram a fence post into your overalls.”

“Nope!” he bleated, as his fight or flight response kicked in.

Even if she wasn’t family, he was not about to get trapped by some lust-crazed mare - not again. As he attempted to step by her, keen on making his escape, she shot to the side and grabbed his shoulder. There weren’t many who were brave enough to try and stop him, and fewer still who actually could, but she was an Apple and an earth pony. Giving him a rough shove, causing him to stumble into one of the supports, she stepped over and pressed her tits against his abdomen.

“I wasn’t asking,” Babs darkly chuckled, flicking one of his suspenders free.

Before he could respond or say a word, she unclasped the second band of denim and let his bib fall free. She’d meant for it to be funny, to tease him and let him get away, but she’d made a fatal miscalculation. As the fabric fell from his chest, unveiling his pecs and rock hard abs, she was given a moment for pause - a pause which spelled her doom.

Seeing an adonic stallion in the flesh was rare enough, but smelling one was an exceedingly rare treat. As she subconsciously took a breath, filling her sinuses with the ambrosial musk permeating from him, a shiver of excitement ran up her spine. Not only did he look like a dreamboat, but he smelled downright heavenly. With her senses besieged, and the primal parts of her mind coming alight, her once innocent motives shifted.

Mac’s jaw flapped, yet he couldn’t make a sound. He couldn’t speak - heck, he could barely even breathe, as she languidly stepped back and crossed her arms over her chest. Despite his mounting anxiety, his eyes wandered down to her tits. Easily a D Cup, or maybe even an E, her pair of melons taunted him, almost begging to be squeezed, which did little to help his painfully turgid cock.

“Like what you see?” she mused, taking one tit in each hand.

As she pressed her breasts together, relishing the power they afforded, she grinned. Playing with a stallion was too much fun, especially one who’s body betrayed their thoughts, and she wasn’t about to let her cousin get away - not until she’d had her fill. Abandoning her rack, slowly moving her hands down her abdomen, she fiddled with the button on her shorts.

“You wanna see?” she whispered, undoing the button and languidly pulling her fly open. Though Mac was deathly silent, he slowly nodded. “But,” she tutted, abruptly stopping, “you’re gonna have to show me yours…”

Mac continued to nod, even though he hadn’t the foggiest idea of what she’d said. Hitching her thumbs over the waistband of her shorts, steadily pulling them down her legs, she gave him the first peek of her bare loins. Slightly darker in tone than the rest of her coat, the plump, ripe mound of her marehood was slowly revealed; it was the hottest thing he’d seen in years, possibly ever, and it left him utterly dumbfounded.

With the shorts around her ankles, Babs kicked one leg, caught the abandoned garment, and spun it around one finger. His expression was adorable, but that wasn’t what she was focused on. Closing the gap between them, nonchalantly draping the sweaty and slightly moistened article against his snout, she sank into a deep squat. She’d shown him the goods, and now she was about to see just what sort of equipment he was rocking.

Her positioning couldn’t have been more perfect, with her face coming to rest squarely at the level of his groin. Extending her arms, grabbing the denim over his waist, she hauled his pants downward. Getting the damn overalls off of him wasn’t nearly as easy as she’d thought, given how snug they were, but she gradually made progress. It was only when the blue fabric began to expose his crotch did she slow.

Like a filly on Hearth’s Warming, she felt like she was unwrapping a present. Sluggishly dragging the garment towards the floor, revealing the impossibly thick root of his carmine tool, she was filled with awe and dread - still, she couldn’t bring herself to stop. If she hadn’t known better, gazing longingly at the obscene appendage, she could have sworn she was looking at an arm.

As the article cleared the tip of his monumental stallionhood, allowing his cock to spring free, her cunt hungrily clenched upon itself. Thicker than her wrist, and well over a foot long, his endowment was easily the biggest dick she’d ever laid eyes upon. Instinctively drifting closer, giving herself a closer look, she caved to her impulses.

“God damn - what have they been feeding you?” she halfheartedly joked, wrapping her fingers around the trunk-like base of his length.

Like a deer in the headlights, it was all Mac could do to helplessly stand there and watch his cousin stroke him off - at least, that’s what he told himself. Her soft palms and slender fingers felt amazing, setting his pulse to quicken, but the sight - stars above, the sight was awe inspiring. With her tits exposed, reverently smiling and jacking him off, she looked like a porn star.

As if having a mind of its own, Babs' free hand drifted between her splaying legs and to her drooling marehood. It had been ages since she’d gotten laid, with that stallion having been a fraction of Mac’s size, and the devil on her shoulder practically begged her to keep going. If he looked good, and he smelled good, and he felt good, she was left to wonder how good he would taste. Awkwardly sidling to the side, bringing herself to squarely face off against his monstrous member, she angled his length towards her muzzle.

“Just watch the stairs,” she blurted, staring down his gargantuan length.

“Eeeyup,” he muttered.

He felt sure that she’d said something, but he was too aroused to give it much thought. Leaning in, she opened her maw and invitingly rolled out her tongue. He wondered if she’d actually be able to suck him off, considering the head of his cock was roughly as wide as her muzzle, but she seemed determined to make it work. As she gave the blunt tip of his shaft a kiss, silently introducing herself, she pressed forward and worked him past her lips.

Babs figured she’d have a hard time, but her eyes had definitely been bigger than her mouth. Unless she could somehow unhinge her jaw, she sure as shit wasn’t going to be able to properly fellate him; even if she could open her snout wide enough, she felt certain that he’d be in her stomach before he was hilted - that being said, she was no quitter. Breathing through her nose, massaging his glans with her tongue, she made out with his cock while slipping two fingers into her slavering nethers.

With her sinuses flooded by his earthy scent, staring at the lightly colored tuft of fur on his crotch, the salty, cloying flavor of his sweat and pre-cum coated her palate. She’d been absolutely right, every single part of the big bastard was magnificent. Ramming her head forward, determined to see how far she could go, she shoved him to the back of her throat and started sucking him off in earnest.

Twisting her muzzle from side to side, while she bobbed her head, she did everything she could to blow him - nevertheless, it was a herculean ordeal. Her jaw strained, simply unable to open wide enough, but that may not be a huge problem. Plunging a third and fourth finger into her snatch, giving her entrance a good stretch, she peered up at her cousin’s gobsmacked face.

As they locked eyes, peering at one another, the two came to a sudden realization - two in fact. For starters, what had begun as a dubiously playful and depraved bullying session had taken a hard turn - secondly, neither of them wanted to stop. Mac was so hard that it hurt, while Babs’ marehood was leaking like a busted faucet. They’d crossed a line, there was no going back, and their budding lust demanded they see it through.

Shuffling back, and taking care to mop his length with her lips, Babs withdrew and cleared her muzzle. Streaks of saliva, pre-cum, and lipstick marked the first few inches of his shaft, a clear indicator that she hadn’t even made it a quarter of the way down his tool. As she steadily pushed herself up, taking care to briefly sandwich his member between her tits, she got to her feet.

Stepping forward, she slipped a leg over his stallionhood, rested her cunt against the base of his dick, and squished her tits against him. There was no way in hell she was going to let him get away without feeling his behemoth filling her, and she had a feeling he felt the same way. As she walked two fingers up his torso, giving his nipple a little flick, she rocked her hips back and forth.

“Well, since we’re both here, you wanna try something else?” she quietly inquired, her words positively dripping with lecherous intent.

Mac gulped, reading between the lines. Between the few drinks he’d had, how insistent Babs was, and the heat of her loins against his tool, his reluctance withered and died. Lifting a finger to reply, yet not knowing exactly what to say, she abruptly shifted and stepped away. Without saying a word, strutting bare-assed over to one of the support beams dotting the vacant area, she bent over, spread her legs, and slapped her ass.

If he was being completely honest, he’d seen pictures in PlayColt that weren’t half as alluring as the sight. Her marehood winked and dribbled her feminine juices to the floor, giving him a peek at her succulent, pink interior, but the look on her face was somehow even more enticing. Bearing a smug grin, knowing exactly what she was doing, she was the spitting image of a succubus.

Taking one step forward, followed by a second and a third, he numbly shuffled towards her. His stallionhood was like a dowsing rod blindly leading him to sin, but he was well past the point of caring. As his hands crept out, resting on her ample, foal-bearing hips, he was stricken by how ludicrous the situation was - not because he was about to rut a distant relative, but because how perfect she was.

She stood at just the right height to let him plow her, being neither too tall nor too short, and he reeled from how bold she was. Bucking his hips, grinding his length between her thighs and against her heated muff, he shuddered. If she wanted him that badly, having gone so far as to seduce him, blow him, and get him naked, he’d be good and sure to give her just what she was itching for - after all, she was family…

Reaching back, running her fingers along his divine length, Babs lowered her waist and brought the tip of his cock to her entrance. If she’d been blindfolded and someone had claimed a fist was pressed against her snatch, she would have believed him. The enormity of it all, feeling as though she was about to be split in half, filled her with a heady cocktail of fear and excitement, yet she wasn’t about to back down.

Gathering her courage, fueled by desire, she slammed herself backwards. The move was foolishly impulsive, impaling herself with nearly half of his shaft, causing her to gasp. Fullness didn’t begin to describe the sensation of having something so large inside herself. She’d fooled around with a couple of bigger stallions before, but this - this was something entirely different.

Gnawing his lip, relishing her snug confines, Mac tightened his grip. Like molten silk, practically demanding he reciprocate, her interior embraced him and spurred him on. Bracing his hind legs, making sure neither of them were going anywhere, he finished what she’d begun. With one, unstoppable plunge, he hilted himself and started fucking.

Babs' knees buckled, her eyes rolled to the back of her head, and a torrent of nectar erupted from her stuffed cunt. In a single move, he managed to push past her cervix and bottom out in her womb, evoking quite possibly the most powerful climax she’d ever experienced. With one shoulder pressed to the beam, holding on for dear life, the titan pummeled her from behind.

Her breasts swayed beneath her, as he reshaped her marehood to suit his needs. Her strength had carried her through most of her life, allowing her to have her way or brute force solutions to problems, yet it did nothing for her now. Against her colossal cousin, she was as completely powerless - no, she was his bitch, and she loved it.

Steadily acclimating to the immense intrusion, gathering her wits, she swung her ass back to meet him. Some shred of her refused to relent, to be bent over and plowed like a drunk sorority girl, and he needed to know that. Clamping down around him, practically fighting to keep him within her depths, she milked his length with all the subtlety of a professional wrestler.

Unsure of where to look, torn between gazing at her face or his stallionhood plunging into her cunt, Mac increased his pace. The tautness of her entrance was eclipsed by just how tight her inner gate was, compelling him to tap into his full potential. In addition to being a stunner, she was the first mare who’d ever managed to handle all of him - a fact he had every intention of savoring.

As the merriment and festivities of the first floor drowned out the soft sounds of their pounding hips, pleased grunts, and salacious groans, leaving the partygoers woefully ignorant to the depravity going on above their heads. There was more than enough excitement for the pair’s absence to go unnoticed, allowing them to lose themselves to the passionate tryst. With the music blaring the excitement growing, they gradually picked up the pace.

“H...harder you - Oh fuck - big bastard,” Babs growled, rhythmically constricting and relaxing her snatch around him.

Mac grunted, eager to oblige, as he ratcheted up the intensity. He’d never been able to go all out with a mare before, having to restrain himself in the past, yet that concern didn’t apply to his cousin. Remarkably durable, unyielding, and startlingly aggressive, she fanned the flames of his lust. Pulling out all the stops, with his meaty, fist-sized nuts slapping against her clit, he grit his teeth.

Babs' worked his cock as best she could, giving nearly as good as she got, but it was a losing battle. The deck was stacked against her, with the stud having both size and mass on her, not to mention his insanely thick tool, her efforts slowly waned. It wasn’t like she wanted to give up on the struggle, yet the wondrous sensations he afforded were impossible to resist.

The balance of power lazily shifted, leaving Mac in complete control. Neither of them had intended for the passionate exchange to end up as a struggle, but Babs' domineering nature had been her undoing. Against the full carnal might of the mountainous stallion, she never stood a chance.

The zeal of her motions faded, as he exerted himself. Sensing her weakness, he slipped one hand from her waist to her tail. As he grabbed her dock, pulling her back while pounding into her, his ripe balls churned and snuggled up to his groin. Lost in the moment, slipping into a rut-lust, he failed to realize how close he was to his limit.

Her thighs trembled, the pitch of her mewling groans raised an octave, and an all too familiar sensation of warmth blossomed within her. Despite having cum once already, she was rocketing towards a second climax. Wrapping her arms around the thick wooden post, practically whimpering with delight, what little resistance she had faded.

Setting his jaw, Mac snorted. His higher functions faded away, replaced by the bestial id at his core. The steady pounding of his hips devolved into rapid, almost frantic thrusts, as his natural urges took hold. He was fucking a mare, a mare who was both charming and strong, and it triggered a deep-seeded need within him - the need to breed.

“D...don’t stop!” Babs blared, feeling as though she may give out.

Heedless of his flaring cock, his wildly throbbing shaft, or his blinding pace, she wanted more. Though she had no way of realizing it, her ovaries took note of the unparalleled rutting and went into overdrive. Somehow managing to stay upright, through sheer force of will, she remained on her feet. She wouldn’t be satisfied until he’d given her everything he had, and that included the content of his pendulous nuts.

On and on they went, reduced to little more than a pair of wild animals, until the inevitable happened. Hauling on her tail, and simultaneously issuing one final, tectonic plunge, he entombed every inch of his length within her. For one brief, fleeting moment, time stood still, before they were wracked by a cataclysm of ecstasy.

Pints of scalding, virile foal-batter surged through Mac’s pulsing shaft, as the mare in his grasp nearly collapsed. Acting on instinct, extending one arm, he grabbed her shoulder, pulled her upright, and impulsively bit the base of her neck; he never would have done something so brash, had he been in his right mind, yet his primal yearnings had gotten the best of him. Awash with bliss, pumping shot after shot of his load deep into her spasming marehood, he held her to himself.

Babs' mouth hung open in a silent scream of rapture, as the world fell away. She’d always heard that it was possible to black out from a climax, but she hadn’t thought it was possible - that was, until that moment. Her vision tunneled, her limbs went slack, and an inescapable bliss overtook her, as she struggled to stay conscious.

Locked together, riding out their near-tandem orgasm, a euphoric warmth gradually settled over them. Mac was the first to recover, shaking his head and looking at his cousin’s cum-drunk face. He figured he’d given it to her pretty rough, but even he was surprised with just how contented she looked. Bringing one arm around her torso, holding her steady, he gently patted her cheek.

“Wha...I’m - uh -” Babs incoherently mumbled, as her higher functions slowly returned.

She felt fantastic - no, better than fantastic, but she was also exhausted. Wearily peering down her chest, between her breasts, she did a double take. Her belly, once soft and relatively flat, had nearly doubled in size. Poking her abdomen in disbelief, feeling a volcanic warmth within herself, she turned her head and peered back at the stud.

“H...holy shit! Dude, you cum like a fucking fire hydrant!” she guffawed, watching his cheeks darken.

“E...eeyup,” he falteringly noted, rubbing the back of his neck.

Easing her down, making sure she had her footing, he stepped back and gently pulled his softening cock from her. With a wet pop, and a small splash of spunk, his stallionhood flopped free. Though there was the slightest touch of shame for what he’d done, comprehending that he’d caved to his sexual impulses and plowed his cousin, his regret was fleeting.

“Fuck,” she thought aloud, turning to face him. “There’s so fucking much!”

Caressing her tummy, feeling his seed sloshing around within herself, Babs grinned like an idiot. To see and feel his unfathomable load was both funny and amusing, though it inspired an idea. Walking over to him, lightly grabbing his jaw, she pulled his face downward, looked into his eyes, and gave him a tiny kiss.

“If I get knocked up because of this,” she softly clucked, grabbing his semi-flaccid dick, “I hope you’ll take responsibility.”

Swallowing hard, Mac nodded. “Eeeyup.”

“Good boy,” she purred, locking lips with the stud.

Though she’d meant it was a joke, a simple throwaway line to cement her authority, she couldn’t have fathomed how prophetic the remark was...
