Familial Fraternisation

Warm water cascaded over Babs’ back, as she lowered herself into a deep squat in the shower. Even over the smell of shampoo and soap, the scent of Mac’s loins was, as always, an aromatic siren’s song. As his fingers moved through her damn mane, lovingly stroking her head, she kissed her way up his semi-flaccid shaft.

It wasn’t like their relationship had ever been bad in any way, but things had taken a pleasant turn after he’d screwed her brains out a month prior. Not only had he regained his vehemence in the bedroom, plowing her with renewed strength and vigor, but he’d become more doting over her as well - of course, that may have been because her due date was less than a month away, but she’d never gotten an actual explanation from him. Regardless of why he’d decided to take the kid gloves off, she was pleased that he’d stopped coddling her.

Her titanic breasts slumped to either side of her obscenely huge belly which hung between her parted thighs, as she affectionately fondled his balls. Though it was her first time being pregnant, a nagging feeling already told her that their foal would inevitably have a little brother or sister - possibly more than one. Grasping the root of his stallionhood, appreciating the sheer heft of his tool, she angled his length towards her face and opened her maw.

It wasn’t like Mac had expected to get a blowjob in the shower - then again, he wasn’t about to complain about the impromptu oral. Shuffling forward, keeping his eyes on her face, he slipped his cock into her awaiting muzzle. Stars above - having his dick sucked by anyone would have been great, but watching the gravid mother of his child eagerly serve him never failed to get his motor running.

While he’d been initially reluctant to admit it, he’d eventually come to terms with his attraction to expecting mares. Their full stomachs, udder-like breasts, and the added padding of extra weight stimulated the baser, stallionly portions of his mind, captivating him with their fertility. His mate had gradually metamorphosed into a paragon of maternal sensuality, elevating her eroticism and appeal to a nigh-unimaginable level.

As her lips wrapped around the tip of his length, feeling the warm embrace of her snout, he peeked down to her leaking bosoms. Each tit was bigger than his head, and needed to be drained of milk daily - a task which he’d grown to love. He still used the milking machine fairly regularly, if only because of her prolific output, although he rarely failed to nurse upon her himself. Fighting the urge to buck his hips, allowing her to take the reins, he cradled the base of her skull in his giant palm.

Babs hummed him, periodically sneaking glances up to his adonic face. He really was a handsome bastard, regardless of which part of him she was looking at, yet there was something undeniably arousing about looking up at him while she sucked him off. Lowering one hand, reaching around her tummy, she rubbed her aching marehood.

It wasn’t like she’d planned to choke herself on him during their morning shower, but her lustful compulsions had reached a fevered pitch. The hormones of being knocked up were insane, as bad or worse than going through puberty, and they were nearly impossible to stop - hell, she’d woken him up two nights ago simply because she needed his dick. Thankfully for her, he always made sure to take care of her every need, even if it meant periodically keeping him up late or interrupting his work.

With the first third of his dick in her mouth, lavishing the underside of it with her tongue, she extended her free hand, grabbed his gorgeous ass, and pulled him closer. Taking the cue, like the divine stud that he was, he started slowly bucking his hips. As he effortlessly plunged down her gullet, her eyelids fluttered.

The funniest thing was that she’d never even been all that interested in giving blowjobs, until she’d hooked up with Mac. Maybe her interest stemmed from the fact that he was hung like a log, or possibly his imposing size had awakened some latent, feminine needs of hers - regardless, being dominated by him was easily the best sexual experience she’d ever had. Finger-fucking herself, taking sips of air if and when she could, she felt his fingers tighten around her head.

Mac swallowed hard, realizing all too well what she was doing. Her little schemes had become commonplace, with her trapping or seducing him into rutting her, and it was getting harder and harder to stave off her advances - not just because he adored making fiery, passionate love with her, but because he found her absolutely irresistible. Feeling her hand slip from his backside, he watched her heft one breast, grab the nipple, and squeeze.

Milk sprayed from her teat, splashing over his shins and pattering into the basin. If they hadn’t been in the bath tub, they would have made one heck of a mess - fortunately, that wasn’t an issue. Subconsciously increasing his pace, jamming himself down her throat, he snorted. If he’d known that his little cousin would mature into such a beautiful and sultry young mare, he would have had his eyes on her much, much earlier.

The snugness of her gullet was only countered by the sinful look in her eyes, as she peered up at him. The combination of sinful look and unparalleled carnal skill was a deadly one, made all the more jarring when she forced herself forward. Her lips stretched over his girthy medial ring, her nose closed on his groin, and he could all but see her throat bulging outward from the immense intrusion, yet she’d done it of her own accord. It was only when she kissed the very root of his tool did she pat his thigh and withdraw.

Taking her time, despite the burning sensation in her lungs, Babs steadily retreated. Having a piping hot load of foal-batter pumped directly into her stomach would have been a nutritious way to start the day - then again, there was somewhere else she’d rather receive a deposit. As the blunt head of his dick cleared her snout, she grunted and stood to her full height.

The big lug gazed down at her, bearing a smitten, idiotic grin, which brought a smile to his face. She’d initially assumed he was a bit simple, seeing as how he’d never gotten much of a formal education, but that couldn’t have been further from the truth. He was, so far as she could tell, remarkably resourceful, practical minded, and keenly observant - that being said, his hulking stature and intellect wouldn’t stop her from putting him in his place.

“Just wanted you to remember,” she murmured, pressing her belly against his lower abdomen. “This,” she continued, awkwardly grabbing his turgid length, “is mine, so don’t you forget it.”

“N...nope!” Mac stammered, shaking his head.

Heaven help him, he loved when she was covetous. He knew he could overpower her, and could likely give her a run for her money in mental games, but her borderline arrogance and confidence made him feel small in comparison. Seeing her cheeky grin, noticing a small movement from within her belly, his hands drifted to her abdomen.

Gingerly pressing one palm against her stomach, holding his breath, he waited to feel a kick. The doctors had offered to reveal the sex, telling him and his lover whether they’d be having a colt of a filly, but they’d decided not to bother. Their child, like their budding relationship, would be a pleasant surprise to both of them.

Taking a step back, moving to the very back of the tub, he leaned forward and brought his muzzle to her rounded midsection. She endearingly picked on him for giving their unborn son or daughter so much attention, telling him that he was going to spoil the foal, but he couldn’t care less. Lovingly kissing her tummy, whispering a silent I love you, his affection was broken by a chuckle from above.

“If I didn’t know better, I’d say you planned to knock me up,” Babs tittered.

Lifting her arms over her head, turning her torso from side to side, she batted his face with her mountainous mammaries. His reaction was, as always, painfully predictable. His eyes widened, his muscles tensed, and he went to straighten up - that was, until she stopped him in his tracks. Grabbing the back of his head, keeping him from standing, she wrenched him forward and buried his face between her tits.

“Maybe,” she mused, turning his head and bringing a tit to his muzzle, “you’re already planning on pumping another foal into me once I’ve had this one. I bet you’d say something sappy like, ‘Eeeeyup, our little one needs a few brothers and sisters to keep ‘em company’.” Just as his lips wrapped around her teat, denying him the chance to drink from her, she pulled him away. “Does that sound about right?”

Mac opened and closed his mouth, but he was unable to speak. Somehow, she’d called him out on his lecherous fantasy. Though he would never force her to do anything she wasn’t comfortable with doing, he had been giving more and more thought to siring several children with her. Holding up a finger, hoping to buy himself some time, he anxiously cleared his throat.

“Oh I don’t want to hear it, Mister,” she lightheartedly huffed, pressing a finger to his lips. “I bet it wouldn’t take you a day to lock me into a mating press - once we get back from the hospital, that is. As soon as my poor, defenseless womb is vacant, you’ll probably breed me non-stop for the better part of a week straight, only taking breaks so you and our little bundle of joy can nurse off these.”

Her bawdy rant abruptly halted, as she lifted one enormous breast in each hand. Unless their foal had a bigger appetite than Mac, she could already tell that she’d be productive enough to share her milk with the kid and her stud. Theatrically grabbing her nipples, wringing the cream from the delicate buds, she suppressed a shiver of delight. She could have left things there, laying a bit of bait on the line, but she was far from finished.

Wheeling around, leaving her profoundly plush posterior pointed at him, she bent forward and fetched her shampoo. On the remarkably slim chance that he didn’t end up plowing her, she still had to get washed up - as such, she may as well try to clean herself. Merrily humming to herself, swaying her ass from side to side, she felt something long, hard, and immensely heavy glide between her buns - jackpot.

Mac’s limit had been well and thoroughly tested, leaving him in a bit of a pickle. While he would have liked to turn her down, if only to say he could claim a small victory, he knew better. On the perilously few occasions when he’d tried to dismiss her advances, she’d become rather enthusiastic. Unwilling to deal with what would doubtlessly be a particularly rough session, likely resulting with broken or damaged furniture, he acquiesced - at least, that’s what he told himself.

Grabbing her waist, he reared his hips back, brought the head of his cock to her winking entrance, and plunged into her. Her depths embraced him like a glove, as though she was made for him, yet she was far from what he’d describe as loose. Whether she was naturally resilient, did kegels to retain her lower grip, was on some sort of supplement, or some combination of the three, he honestly couldn’t say, but he’d failed to fully break her in.

Stopping just as his medial forced its way into her entrance, he gave her a moment to acclimate - heck, he gave both of them a moment. Being ambushed with an amorous advance was never easy to deal with, but having it happen so early in the morning was particularly difficult. Had she not been about to pop, he would have begun pounding her with reckless abandon - sadly, given that her due date was right around the corner, he had to rein himself in just a touch.

Rolling his hips back, hauling all but the first inch or two of his member from her marehood, he playfully slapped her rear, steadied himself, and started thrusting. As much as he loved railing her missionary, there was something undeniably magical about taking her from behind. The glimpses of her bliss-wracked face, seeing her bosoms swing beneath her, and watching her lower lips being rhythmically dragged out and stuffed back in was better than any porno in existence, yet it paled in comparison to the sensations she afforded.

Babs hadn’t expected to break him so easily, yet the heavenly feeling of his meaty dick stretching her out and scraping against her g-spot made it impossible to protest. Her hands shot forward, bracing her against the wall of the shower, as she rocked back to meet his pounding hips. The water flowing over her lower back and behind was a pleasant addition to the experience, once again reminding her that they should have more amorous moments in the shower, but she’d likely forget about it once they were finished.

As silly as the thought was, she often wondered if her older cousin had some unicorn blood flowing through his veins. Intimate sessions with him often left her weak and seemingly robbed her of the ability to think clearly - neither of which had happened with any of her past partners. Clenching around him, leaving her bosoms to drip dairy to the tub, she bucked back against him.

No matter how many times they fucked, the positions they did it in, or the hour of the day, the sensation of having his gigantic bitch-breaker never got old; it was always - always intense, and she prayed to the heavens that she’d never tire of it. The only drawback to having the crimson titan as a lover, if it could even be considered a drawback, was toting around their colossal lovechild - still, that was a petty grievance. If becoming a foal-factory for the behemoth meant she’d be bedding him until the end of her days, that was a small price to pay.

“Fuuuuuuuuck,” she absentmindedly groaned, as a particularly deep plunge knocked against her cervix.

The jolt of pleasure momentarily disrupted her thoughts, giving her a split second of clarity. She’d had sex with him more times than she could count, in more places than she cared to admit, which allowed her to realize that, much to her chagrin, he wasn’t using his full potential. His ministrations felt great, there was no doubt about that, but the last thing she wanted was for him to take it easy on her, whether she was pregnant or not.

Summoning every bit of her willpower, before she passed the point of no return, she did the unthinkable. Out of the many, many times they’d made love, she’d never once put things to a halt, until that moment. Straightening up, putting her impulsive scheme to work, she turned, pressed a hand to his chest, and glowered up at him.

“You can stop now,” she muttered, bringing his motions to a grinding halt.

Before he could reply, hoping she hadn’t just fucked herself out of a sublime rutting session, she stepped out of the shower. She had no real way to know if her ploy would work, especially because she dared not look back at him, but she couldn’t bring herself to half-ass the act. As she gathered up a towel, she strutted out of the bathroom and towards their awaiting, unmade bed.

“I’ll just wait until you’re finished,” she hollered, unable to completely give him the cold shoulder.

Standing like a statue, Mac mutely watched her depart. Out of all the things she could have done, he had not expected her to stop dead and leave him hanging - both literally and figuratively speaking. So far as he knew, he hadn’t done anything to upset her - heck, if anything, he’d done just what she wanted to do. Having lost all interest in the shower, wondering what in the world had gotten into her, he stepped out of the shower, moved to the doorway, and peeked into the bedroom.

His eyes widened, his jaw went slack, and the cooling blood in his veins ran hot, as his eyes settled on her. Laying on her back, directly on the center of the spacious mattress, his mate was shamelessly getting herself off. With her nethers almost perfectly angled towards him, he watched her kneading and twisting one teat with her left hand, while feverishly massaging her clit with the other.

Though the sight was arousing to a fault, it only compounded his confusion. If she was pent up enough to abandon their shower to go and masturbate, why in the tarnation hadn’t she let him slake her thirst. Pondering on the subject, hearing her lightly moan and writhe on the blankets, he kept coming back to the same conclusion - she was upset because he hadn’t adequately performed his studly duties.

The notion of displeasing her would have been alarming, had he not realized he only had himself to blame. While he had been slightly rougher with her lately, he’d been continually mindful to restrain himself. His primal instincts raged against his genteel upbringing, demanding that he give his lover what she wanted - no, what she needed. Snorting in frustration, feeling both ashamed of himself and extraordinarily aroused, he stomped towards the bed.

Keeping her eyes shut, hearing the giant’s heavy footfalls drawing nearer, Babs theatrically groaned. She’d gone so far as to lay the trap, leaving him to his lonesome, and even put on a show of getting herself off, so adding a bit of lustful noise to the mix certainly wouldn’t hurt anything. As she felt the bed shift and creak under his weight, sensing him moving between her legs, her heart skipped a beat. Maybe, just maybe she’d get what she wanted after all.

First one thick-fingered hand wrapped around one ankle, then he mirrored the movement with the other, before her legs were slowly lifted. Allowing him to do as he pleased, feigning ignorance, she sank two fingers into her snatch. If he was going to plow her senseless, it would be up to him to seize the initiative.

Her motions only came to a halt when she sensed him move, feeling what had to be his stallionhood slide over her crotch. Peeking up at him, seeing her legs resting on his broad, statuesque shoulders, the breath hitched in her throat. Unlike his typically tranquil expression, a broad, almost twisted grin split his features. It was at that moment she knew she’d fucked up.

Clutching the base of his length, slapping his turgid dick against her hand, Mac waited until she’d withdrawn her arm to get into position. If she thought he wasn’t enough of a stallion to tend to her every need, she was egregiously mistaken. Towering over her, utterly dwarfing her gravid form, he leaned forward and drove his shaft into her awaiting cunt. Being surprised by her amorous advance had been fun, and he’d been happy enough to oblige her, but this was different - this time he was serious.

Supported by his arms, with his hands braced to either side of her chest, he really started fucking. Twisting and tugging on her moistened nipples, causing milk to stream down her fingers and over her heavy chest, a blissful moan escaped her - that was, until he silenced her with his tongue. His head shot downward, locking lips with his not-so-little harlot, while he savagely bucked his hips.

Even though he’d just started, Babs could immediately tell the difference from a few minutes prior. He thrusted harder and deeper than before, she could feel his length pulse in tune with his thundering heart, and the raw passion he exuded was palpable - in short, she’d taunted her bull and now she was getting the horns. As her eyelids drifted closed, relishing the sensation of his wildly pistoning stallionhood, she breathed hotly on his face.

This was where she belonged: on her back, legs up, serving as an outlet for her stud’s sexual frustrations. Had any other stallion even thought about pinning her down, she would have easily thrown them off and ridiculed them, but not Mac - Mac was different. In an all too real way, he was the embodiment of everything she ever wanted in a mate, and she would willingly devote herself to him to keep him.

Inspired, yearning for more, she wrenched her head to the side and bit down on his ear. “Fuck me like you mean it, Stud.”

If her legs had been free, she would have aided in his thrusts - unfortunately, all she could do was knock her heel against his upper back for encouragement. Pulling away ever so slightly, fully intent on making out with him, the unthinkable happened. Supporting himself with one hand, he grabbed the base of her skull, turned her head, and aggressively kissed her.

Her battered sex excitedly spasmed, and her toes curled, when he aggressively frenched her. It was rare enough to have him get rough with her, since she was nearing her delivery date, but to have him be that forceful was something entirely new. Briefly fighting back against him, spurred by her hubris, her resistance crumbled under his carnal assault. She knew she was his - he was just reminding her of it…

Quite literally pounding her into the bed, the sound of his lover’s muted groans and whimpers were like a symphony to Mac’s ears. Throughout the entirety of his life, he’d never once met a mare as physically mighty or of such a strong character before, and he’d be darned to the depths of Tartarus if he was going to let her go. If keeping her meant making her his brood mare, railing her whenever and wherever she wanted, it would be a small price to pay.

The way she clung to him, clenching her vice-like depths around his withdrawing shaft, was as amazing as ever. Though he had her trapped under him, she did everything she could to wring his dick dry, to milk every last bit of essence from him. Tensing slightly, breaking their kiss, he pushed himself up and smirked down at her.

“God - Mmmph - damn, you’re a sexy bastard,” she huffed, reaching for his chin.

His smile broadened slightly, as he craned his neck and locked his lips over her left teat. She couldn’t speak for the other mothers in Equestria, but she’d grown very accustomed to the feeling of having someone breastfeed on her - almost too accustomed. Both relieving and pleasurable, the sensation had become a regular part of their bedroom hijinks - hell, they’d even done a bit of roleplaying regarding cows or, on one instance, mother and son depravity.

Running her fingers through his mane, steadily creeping closer and closer to release, her mind wandered. As crazy as it sounded, she’d actually loved every step of her flowering motherhood. She’d never once experienced morning sickness, her libido had skyrocketed, and she pulled off the pregnant look extremely well - so well that she’d routinely caught stallions eyeing her at a distance. Mac had given her something she didn’t know she’d ever want, and she genuinely wasn’t sure if she’d ever be able to repay him.

“Aaaaaahn,” she mewled, as he gingerly nibbled her sensitive, leaking teat. “Fuck me, I love you!”

Mac’s eyes flew open, and he peered up at her beaming face. Somehow, for some reason, neither of them had ever uttered the word love before, and hearing it drove him into a frenzy. He cared for Babs as or more deeply than he’d cared for anyone, despite having only been with her for less than a year, yet he’d never once told her that. Rocking back, running his hands up her legs and to her ankles, he let his actions speak for himself.

Leaning over her, driving her feet to either side of her head, he flew into a rut-lust. His abdomen pressed against her belly, her breasts were all but crushed against his pecs, and he draped his head over her shoulder, as he screwed her with all the unstoppable force of a primordial demigod of virility. Two parts of a whole, yin and yang, they celebrated the completeness that each afforded the other.

Time lost all meaning to the lovers, as they consummate their feelings for one another. Mac atop her, practically plowing her through the bed, while she gleefully accepted every bit of his amorous fury. Moments became seconds, and seconds grew to minutes, while they embraced one another, their feelings, and the life they would bring into the world. Though they’d grown up separated, only seeing each other on rare occasions, they knew they belonged together.

Unable to move, with her arms pinned under her knees, Babs howled out in ecstasy. Good was a pitiful attempt to describe the awe inspiring sensation of being so thoroughly dominated, yet that was only one element at play. He’d been energetic before, after she’d lured him out of the bathroom, but the fervor of his lovemaking had become an order of magnitude greater than anything she’d experienced after she’d said one simple word - love.

“I love you so goddamn much,” she wailed, squirming under him. “Promise - FUCK - promise me you’ll make me a mother again!”

Drunk with maternal affection and lust, her higher functions all but melted. It wasn’t that she’d lied - far from it, in fact - but the raw fury of his intimacy stripped away her reservations and doubts, leaving behind the truth she’d been too fearful to speak. She honestly loved the big bastard, and she adored the fact that he’d shown her her true place in the world - for that, she owed him her very soul. Accepting her feelings for him was something beyond therapeutic, and the mental tranquility it imparted accentuated her catastrophic climax.

Between the oral and cock-tease in the shower, Mac had been riding a hair trigger for the better part of an hour, leaving him vulnerable. The admission from his mare was comforting beyond words, as was the desperate plea for him to sire more foals with her, pushing him past the brink. Without breaking his pace, screwing her with reckless abandon, he came with all the devastating force of a tsunami.

Lost to the tempest of bliss, losing himself, he shifted his face and clamped his teeth on the base of her neck - not hard enough to break the skin, but to further assert himself as her stud. Filling her with his essence was as amazing as it had ever been, regardless of the rather sizable bun in her oven, and so he did everything in his considerable power to hilt her. Filling her completely, feeling his spunk squirt and sputter from her jammed cunt, he rode out his climax.

The octave of Babs’ orgasmic cry raised by several octaves, all thoughts escaped her, and her limbs went limp, as she was overwhelmed by an unstoppable surge of rapture. Though she’d never had a near-death experience, she nearly felt as though her soul may escape her body. In spite of her own crescendo, which had come a split second before her mate’s finale, the pleasure wracking her was singular, somehow different to anything she’d experienced.

Nectar flooded from her depths, erupting from her confines to seep into the blankets and sheets beneath her. To say it felt fantastic would be an understatement, so powerful were the heavenly sensations permeating through her very being. It was, for all intents and purposes, the perfect ending to a perfect morning, were it not for one small fact - the foal within her thrashed violently.

Ripped from her euphoric state, somehow knowing that something was amiss, she squirmed beneath the stallion. Try as she might, with his full weight bearing down on her, she could do little more than fidget in place. Too weak from the experience, yet knowing she had to do something, she bit his ear and drew his attention; the move wasn’t the most subtle thing, especially after such a damn good lay, but it was the only thing she could think of doing to shake him from his euphoric stupor.

“B...babe,” she stammered, swallowing hard, “can you get off real quick?”

Mac nodded, though he couldn’t say why she’d suddenly asked him to move. Releasing her legs, pushing himself up, he shuffled back and dragged his slickened length from her confines. As he peered down at her, seeing her belly flex and bulge, his eyes wandered to the sheets. Their climaxes were often somewhat messy, leading them to do laundry on a near-daily basis, yet something was off. His entire lower half, as well as the blankets and mattress, were absolutely drenched. Looking to her face, as a sinking feeling settled in the pit of his stomach, he gulped.

As he unsheathed himself from her, Babs shivered. It was like a dam had been breached within her, leading to an absurd amount of fluid rushing from her marehood. She’d cum pretty hard before, and nearly always squirted when Mac was rutting her, but this wasn’t right - this was something else entirely. Shakily pushing herself up, miraculously finding herself able to move, she winced.

Not only was their foal feeling very energetic, but an exceedingly distressing ache radiated through her core - it didn’t hurt per se, but it sure as shit wasn’t comfortable in the slightest. Gazing down at her tummy, wondering what the hell had Junior in such an ill humor, realization dawned on her. In her longing to get railed like there was no tomorrow, she’d unintentionally lit the fuse for a moment that both terrified and overjoyed her.

“I - uh -” she croaked, grasping her stomach, “I think we should probably go to the hospital…”
