Ride Below the Crupper

As the sun crept through the window and onto her face, Bloom peeked up at the carmine behemoth’s face. Having thoroughly demolished her bed the evening prior, they’d ultimately retired in Mac’s apartment. Squirming in place, pressing her cheek against his chest, she contentedly sighed and listened to the steady beat of his heart.

She’d always taken comfort from her big brother, viewing him as a pillar of the family, yet her love for him had transcended to something all the more profound. They’d crossed a line from which there was no going back, becoming something more than siblings, and she couldn’t be happier. As she breathed in his ambrosial scent, her mind wandered to what his plans were for the day.

Someone would have to remove the shattered remnants of her bed frame and clean up her chamber, since there was more than likely dried jizz in a number of places, although she wouldn’t be able to lend a hand - at least, not until she was done with her classes for the day. She only had a few months left before graduation, so she really couldn’t afford to play hooky - that and Mac would likely insist she went to school. Wondering if she could concoct some sort of e, scrunching her snout in indignation, a solution for her problem presented itself.

Peeking down his torso, past his sculpted pecs and six-pack abs, she spied the bed sheet tented over his groin. It had been the first time she’d ever actually slept with him, excluding when she was a tiny little filly, so the sight of his morning wood brought butterflies to her stomach and an ache to her loins. Though she’d wanted to share a bed with him after they’d first fooled around, he’d been adamant that she go back to her room for the night - likely out of guilt or unaware of how deeply she wished to be with him. Glancing up at his face, ensuring he was still unconscious, an impish smirk crept across her muzzle.

If she could butter him up enough, starting his day on the right foot, he might feel generous enough to let her stick around the farm to help with chores, but that was a big, big if. Babs wasn’t the type of mare to prioritize Mac’s stallionly needs, so far as she knew, which may give her just the opening she needed. Grinning from ear to ear, she awkwardly rolled off the mattress, got to her feet, and tiptoed to the foot of the bed.

Seconds after she took her first step, a moist sensation against her bosoms caused her to falter. As she glared down at her mountainous breasts, spying twin trails of milk dribbling from her teats, she suppressed a groan. She positively adored her massive breasts, despite having had them for less than a day - nonetheless, it would take some time to adjust to their size, heft, and the fact that she was suddenly as or more productive than the average dairy cow. Shaking her head and clearing her thoughts, she ignored her udders and continued with her spontaneous and salacious plan.

Luckily for her, Mac was dozing on his back with his legs slightly spread, giving her just the opening she needed. Lifting and cautiously crawling under the linens, doing her best not to brush up against him, she ponderously moved closer and closer to his groin. The bouquet of his stallionhood was even stronger beneath the sheets, setting her pulse to race and mind to grow fogged with lust. Be darned if she could explain how her cousin could live with him, because she’d be more than happy to spend every waking hour serving and worshiping him like a god.

Moving at a hastened pace, driven by her subconscious wants, it took her no time at all to reach her prize. Resting just before her was his pillar-like stallionhood, as tall and imposing as some primal monolith, but there was a problem; even propped up on two arms, she wasn’t quite big enough to suck him off angling his length towards herself. Undeterred, realizing he was going to wake up soon enough, she gingerly wrapped her fingers around the base of his shaft, hauled his cock towards her face, and wrapped her lips around the tip of his member.

Though they’d washed up before hitting the hay, she swore she could still taste traces of his potent spunk and her nectar on his supple skin. Her eyes drifted shut, her head wandered lower, and she began to drool from both ends, as the head of his dick glided to the back of her throat. She wasn’t sure if she’d be able to fully hilt him in her snout, but that didn’t mean she couldn’t give it her best shot. While she bobbed her head and fixated on the wondrous flavor of his bare flesh, getting increasingly worked up by the act, she failed to notice him shift ever so slightly.

Mac stifled a yawn, awakened by the blissful sensation of something warm and wet around his morning wood. He couldn’t remember the last time his mate had been kind enough to give him a good morning blowjob, and the considerate gesture brought a gratified smile to his face. Babs really wasn’t a bad pony - a bit hard-headed and strong willed, sure, but far from bad! Lowering one arm and lifting the cover, fully expecting to see the fuchsia mane and tanned coat of his lover, he was met by a pair of amber eyes.

The sight nearly made his heart stop, he struggled to comprehend what he was seeing. He’d never functioned well right after waking up, typically giving himself a full hour, a shower, and a few cups of coffee before he could start his day in earnest, so it took a moment for the memories to come flooding back. Flashes of himself and Bloom assailed him, of the debauchery they’d enacted over the last few days, and he was a bit shocked to find her nonchalantly sucking him off.

He couldn’t be upset that she’d become so amorous with him, seeing as how he’d ultimately plowed her senseless and apparently ignited some maternal desire within her, yet she should’ve known better than to nonchalantly get frisky; she knew he was in a relationship with Babs, with their cousin no-less, and that he had one child and another on the way. Even if he was totally fine with knocking her up, which he may have already done, having a foal with his sister and their cousin might set a new incestuous record for the Apple family - besides, she hasn’t even gotten her diploma yet!

Turning his head and glancing to the side, seeing that she had less than an hour before school was supposed to start, he knit his brow. As nice as it would be to get some bed head, he was not about to let her cut classes - not for a second day in a row. Forcing himself to glower down at her, he reached out, patted her cheek, and sternly shook his head.

Bloom reluctantly withdrew, eager to continue but knowing she shouldn’t test him, and cleared her snout of his turgid length. The last thing she wanted was to make him upset, especially since she had every intention of bearing him an heir - that being said, she wasn’t completely out of options. Rearing back, as she straddled one of his muscular thighs, she rose to a kneeling position and shot him the best puppy dog look she could muster.

“Awwwww -” she whined, “won’t ya let me finish ya off at least? Ah know you got a full day ahead, but -”

He petulantly crossed his arms over his broad chest and looked at the clock, cutting her off with his silent response. Her fears had been realized, he seemed adamant that she not dither another day away with him or more lecherous hijinks. Even if she feigned going off to the schoolhouse, there was a very real chance that he’d go to check on her or possibly wait for her after classes. Thinking fast, still unwilling to throw in the towel, the cool, wet feeling on her bosoms gave her an idea.

“Ah can’t go to school like this,” she pleaded, squeezing and spraying milk from her erect nipples. “Mrs. Cheerilee will -”

Swinging one leg up and over her, Mac placed his feet to the floor, rose from the bed, and stomped over to the dresser. Having already dealt with Babs throughout her pregnancy, he’d learned just enough about expectant mothers to address Bloom’s dairy-based dilemma. Opening a drawer and rifling about, it only took him a few seconds to find what he was looking for.

As he tossed her a pair of bra pads and the biggest brassiere he could find, he smugly grinned over at her. If she thought she could taunt him into another hedonistic bout of fucking, she was dead wrong. The first and second times they’d banged were spontaneous, both with elements that had taken him completely off guard, but not this time - this time he was ready. Seeing her lip quiver, he turned away and stepped over to the closet to get dressed.

It was all Bloom could do to watch the giant in awe, seeing him dismiss her advances as though they meant less than nothing. He’d handily defeated her attempt to seduce him, leaving her feeling both defeated and crestfallen. As she crawled off the mattress and got to her feet, she snatched up the bra and pair of pads he’d flung at her.

“Just so you - Ugh - know, Ah would’a done all the work,” she grunted, wriggling into the undergarment. “Yup, would’a ridden you cowgirl and everything.”

Only barely getting the brasserie in place, she peeked over to see if her provocation had had any effect on him. Sadly, though he was still rock hard, his stoic demeanor was in full force. As much as she loved him, seeing his reaction, or lack thereof, was beyond annoying. Churlishly stomping her foot, she threw her hands up in defeat.

“And what am Ah supposed to wear? It ain’t like Ah -” she fell silent, as he tossed her one of his t-shirts and a modest skirt of Bab’s. Staring down at the garments in disbelief, her shoulders went slack. “Thanks…”

Securing his overalls, having chosen to go without a shirt that day, he nodded. “Eeeeyup.”

“You gonna try fixin’ up mah room today? If’n you wait, Ah’ll help once Ah get back,” she asserted, steadily getting dressed.

Moving to the doorway, Mac paused and looked over his shoulder at her. “Eeeyup.”

Without waiting for a reply, praying she’d taken the hint, he saw himself out and to the stairwell. Though he hadn’t shown it, other than his boner, he’d actually considered letting her stay around the farm. She’d almost assuredly get asked about her enhanced physique, and she’d have to answer for why she’d been absent yesterday, but those were her problems to solve, not his. She was smart enough to come up with something, hopefully without mentioning her budding interests in him, which meant he could let her sort things out.

It wasn’t like he wanted to boot her out and make her go to school, but he needed to for both their sakes. He had plenty to do around the farm, not to mention addressing the demolition in her bedroom, and she was very close to graduating. Truth be told, he’d be more worried about Granny Smith killing him because he’d had some part in her flunking over them knocking boots a handful of times. Shaking his head, attempting to get his thoughts in order, he plucked a tool belt hanging from a support beam and plodded off to the homestead.

Cleaning up the damage from their disastrously depraved afternoon would more than likely take most of the day, but that was only the start of the problem. If memory served, her bed had been destroyed beyond any hope of repair, with the frame shattered and mattress all but rent asunder, so he’d probably have to build a new one himself; he would have gone out and simply purchased a new one, but Granny or AJ would probably notice the hit to their family bank account.

As he steadily moved through the farmhouse, trotting up the stairs and down the hallway, he paused at Bloom’s chamber. Things were much worse than he’d remembered; there were cracks in the drywall, the bed was a broken heap of timber, and a pair of her panties hung from the ceiling fan. Pinching the bridge of his snout, swearing that it was the last time he indulged his lewd little sister, he pulled a claw hammer from his belt and put himself to work.

Grumbling to herself, still inordinately displeased that her brother had shrugged off her advances, Bloom stomped down the stairs from the apartment. She could have sworn that he’d succumb to her feminine wiles! Between her expansive bust, enlarged hips, and the fact that he’d woken up with his dick in her mouth, he should have bent her over and done her raw! Stepping to the ground floor and marching to the exit, subconsciously adjusting and readjusting the undersized bra, something caught her eye.

Resting in one corner of the barn was the milking machine they used for the cows. She was well aware of what the device was used for, having used it multiple times as a chore, and the sight of it summoned a particular thought. Since she was leaking milk like a busted faucet, and given that her tits were so full that they were uncomfortable, it would be reasonable for her to drain herself before sitting in class all day ~ right?

Scampering over to the contraption, which was conveniently resting within its box, she snatched up the crate and an empty milk pail, whipped around, and dashed back to the stairs. So long as she didn’t take an hour to relieve the strain on her tits, she should be able to get to school before the tardy bell rang. As she ran back to Mac’s room, the only reasonably private area she could think of, she tried to ignore the rapidly moistening panties clinging to her crotch.

Mac had no way of knowing how long he’d been toiling away, but it had been at least an hour or two. He’d managed to clean up all the debris, hauling all the scrap timber to the burn barrel out back, and started patching the walls - unfortunately, he still had a long way to go. With the drywall repaired, having to leave the putty to set for a day, he could go and check the barn for lumber. If he was lucky, they’d have enough spare timber laying around to cobble together a decent bed frame.

Wiping his brow, he lazily turned and lumbered out and into the hallway. Even if they didn’t have the supplies needed to construct a frame, he could still get a snack for himself - for buck’s sake, what with Bloom’s little distraction, he hadn’t even had the chance to eat breakfast or have a morning coffee. Plodding to and through the house, making for the front door, he wondered how his little sister was handling his refusal.

Things may have been different if it was the weekend, but there was nothing he could do to change it. She only had a few weeks left to go in her senior year, with finals coming up just next month, so she couldn’t afford to miss out on her studies. As he crossed the threshold into the barn, musing on what she may do once he got home, he glanced up and to his apartment door. Buck it, the construction job could wait a little while longer - for the time being, he could really go for something to eat.

It wasn’t until he’d scaled the stairs and trolled into his living room that he noticed something was amiss. Bloom’s book-bag still rested on the couch, meaning one of two things - either she’d forgotten her supplies before she’d left, or she’d disobeyed his wishes and decided to skip her classes; his mood instantly darkened at the thought, as he quickly checked the kitchen then turned and stormed to his chamber. If he was about to walk in on her a third time, so help him, he would sling her over his shoulder and carry her to the school himself.

Bursting through the room to his door, already holding a finger up to chastise his sister, he stopped in his tracks. It wasn’t the fact that he’d found Bloom that immediately derailed his thoughts, it was the state she was in. Buck naked and bent over, resting her head against the top of his dresser, she feverishly got herself off while a milking machine, the very contraption he’d used on Babs multiple times, drained her enormous udders.

Watching the thick, nutritious cream being drained from her tits would have been arousing enough, but fate had thrown him a special curve-ball. Not only had she decided to forego her studies to empty her jugs, but she was furiously masturbating to the process. Lightly panting, finger-fucking herself like it was the last day of her life, she was blissfully ignorant to his intrusion. Clenching his fists, simultaneously turned on and angry with her, he trudged over to her and unfastened his suspenders.

“Oh buck,” Bloom groaned, plunging a third digit into her cunt.

She’d had no way of knowing that the machine would feel so gosh-darn good, so she couldn’t help but rub one out after she’d started. It hadn’t taken long for her to throw in the towel and strip down, overwhelmed by the compulsion to get off before leaving the farm. She hadn’t planned on masturbating through the process - then again, it seemed to be taking forever for her tits to be emptied.

Lost to her thoughts, nudging a fourth finger to her entrance, something reached around her waist, grabbed her wrist, and pulled her arm behind her back. The sensation of thick, calloused fingers against her left her momentarily stunned, allowing the assailant to wrench her other arm from beneath her head. Looking back in a panic, seeing the towering behemoth looming behind her, her pupils shrank to pinpricks.

“Ah…Ah can explain!” she bleated, as Mac effortlessly held her wrists in one hand. “Those pads ya gave me were super itchy, so Ah figured, well, Ah may as well…”

Her desperate explanation died in her throat, as she watched him tug and wriggle his way out of his overalls. The sight of his bare torso, glimmering in sweat, was enough to make her marehood involuntarily wink, yet that was just the appetizer. In no time flat, seemingly in the blink of an eye, he’d completely disrobed, kicked his garments away, and raised one hand above her flank.

“M…Mac!” she stammered, swallowing hard. “Ah ain’t no filly, ya can’t just -”

Smack

His palm impacted squarely on her ass, bringing with it a jolt of pain and, much to her surprise, a thrilled bolt of pleasure. Biting her lip, only barely able to stifle herself, she struggled to recover before the second blow landed - sadly for her, he was faster than her. Effectively immobilized by her big brother, being spanked like she was a foal, an odd mix of emotions roared forth.

While she’d been too young to remember her father, a part of her viewed Mac as a paternal figure. He’d always been there for her, praising her for her successes, supporting her through the hard times, and pushing her to strive, so he was the closest thing to a dad that she had. Being punished by him, after beginning to view him as a lover, evoked a maelstrom of emotions - ultimately resulting in a twisted amalgam of her already perverse perception of him. Arching her back and splaying her legs, her teary eyes shot to his face.

“Ah’m sorry, Daddy,” she mewled, “Ah’ve been a bad filly.”

Having reared back to clap her backside for a third time, Mac froze. Something about the way she’d just called him Daddy struck him as off, but it only took him a moment to figure out why. Shifting his focus from her face to her behind, seeing syrupy nectar leaking from her engorged sex, realization dawned on her. She wasn’t viewing it as a punishment - no, she actually liked the harsh treatment.

In a rare moment of indecision, he faltered. On one hand, he would have been justified in punishing her for her disobedience - on the other, hearing her call him Daddy, while perversely enjoying the discipline was one of the most enticing things he’d ever seen. Glancing down to his stallionhood for guidance, seeing his dick twitch in anticipation, he settled on having his cake and eating it too.

Momentarily pausing his retribution, he clutched the base of his cock and guided it to her slavering entrance. Considering they’d been fucking like jackrabbits in spring for the last two days, he saw no harm in punishing her while blowing off a bit of steam. With the tip of his length kissing her lower lips, continuing to hold her wrists in one meaty hand, he stepped forward, cocked his hips back, and plunged into her awaiting depths.

Bloom shivered from head to toe, as her cunt was filled in a heartbeat. A shuddering breath escaped her, she attempted to rock back against him, and a bead of saliva crept down her cheek, relishing the sense of fullness he provided. The enormity of his endowment was both a blessing and a curse, being wildly intense while ultimately ruining her for any other stallion, but she couldn’t care less; as far as she was concerned, he was the only stud she’d ever give herself to.

Smack

The tinge of pain tore her from her thoughts and brought her back to the present, allowing her to peek up and back at him. “Daddy, please, Ah - Aaaaaahn!”

Mac struggled to keep a grin from breaking his impassive features, as he spanked her a third and fourth time. Caressing her soft, pillowy rear, seeing her flesh redden slightly, his pulse skyrocketed. He couldn’t fathom why disciplining her was as stimulating as it was, but he was so hard that it hurt. Hauling a portion of his shaft from her confines, watching her pink, meaty lips clinging to his length, he began plowing her.

If he’d been in a more twisted situation before, he couldn’t recall it. There he was, rutting his youngest sibling - a sibling he’d probably knocked up, while spanking her and being called her Daddy. If there was a higher power, aside from the Princesses, he prayed they’d forgive him for his hedonistic transgressions, because he’d definitely sinned. Increasing his pace, issuing seemingly random slaps to her backside, his eyes flitted between her jiggling ass, his stallionhood pistoning into her, and her bliss-wracked face.

Every time his open palm impacted against her, sending ripples through her soft buns, she’d moan and fiercely clamp down around him. Her reaction shouldn’t have been that surprising, yet he was impressed that her snug cunt could get even tighter than it usually was. Snorting through his nose, hauling her torso slightly higher, he leaned to the side and peered at her rack.

Though one breast was still affixed to the machine, the other swung freely and sprayed milk over the dresser and carpeted floor. He’d thought Babs had been a productive mare, able to generate nearly a liter of dairy a day, but Bloom obliterated her cousin’s output. More akin to a cow, having already filled the pail beneath her, there seemed to be no end to the rich cream streaming from her teats.

Securing his grip on her, mesmerized by her swaying rack, he gradually pounded into her with increasing force. She was supposed to be getting a punishment, yet her actions smacked of a masochistic bitch who was loving every second of his ministrations. Frustrated and aroused, feeling his domineering side creeping to the fore, his higher functions waned.

He knew he shouldn’t be enjoying himself, although it was a losing battle. Between the heavenly embrace of her snatch, the view of her perfectly curvaceous body, and hearing cries of pain-streaked rapture, his passion roared into an unstoppable inferno. Hauling her arms to his chest, pulling her torso up and towards himself, the force of his hips slamming against her nearly set her off balance.

Bloom’s eyes widened in shock, as the ruinous force of his love all but destroyed her mind. The sensation of being railed by him, bearing the full fury of his rut-lust, was indescribable. He controlled her body, he practically obsessed her thoughts, and she felt like her very soul belonged to him. For all intents and purposes, she was his, whether he knew it or not.

Unable to reciprocate, barely able to keep her balance, she did the only thing she could - she constricted her snatch with all the strength she could muster. She’d always been relatively strong, bearing the physical power of the hardy Apple family, so her vice-like cunt squeezed his cock in its formidable grip. Even on his plunges, feeling her entrance stuffed in by his plunges, she threw her head back and moaned.

Moments before peering over at him, a singular sensation in her abdomen caught her attention. Gazing down her chest, past her wildly swinging bosoms, she spied her belly rhythmically bulging. The sight of his stallionhood disappearing and reappearing within her belly was awe inspiring to a fault, nearly driving her mad with desire - still, that wasn’t nearly as wondrous as her inevitable fate.

Her womb had yielded to his unstoppable might, over the course of less than a week, and yet this was only the beginning; sooner or later, she would be carrying their foal. Though she hoped Zecora’s potion had done the trick, boosting her fertility and ensuring a pregnancy, she’d get impregnated by him whether he liked it or not. She wasn’t normally one to do anything underhanded, but she’d break into his room and ride his dick if she had to.

The thought of herself growing gravid, carrying their lovechild, was enough to push her to the brink. As his free hand wandered up her waist and to her chest, ferociously squeezing her unmolested teat, she howled. She was so close, so very close to cumming that she felt like she may go mad, but that changed in an instant.

As he leaned forward and rested his head on her shoulder, leaving her to presume she’d get a kiss, he undid her completely. Instead of any tender act of affection, he angled his muzzle and bit down on her collar. The spike of pain was devastating, sending her sailing into a tumultuous sea of raw ecstasy.

Mac clenched his teeth on her delicate flesh, blinded by his primal longings. Gone was the loving, kindhearted stallion he was, replaced by a ferocious god of virility and conquest. His thrusts reached a fevered pitch, his nostrils flared, and the head of his dick battered against the back of her foal-factory, all while her cervix and marehood milked him with the unbridled enthusiasm of a god-tier broodmare pining to be bred.

Her climactic scream and the marish juices gushing from her spasming cunt were the final nail in his coffin, pushing him over the edge. Fully hilting himself, burying every inch of his throbbing length within her, the tip of his stallionhood rapidly expanded to its full size. As his virile essence rushed into her depths, bathing her interior, he grunted with every fitful thrust of his powerful hips.

Though she was still very much his cherished sister, the past few days had elevated her status to something more than that. He still loved her with all his heart, but it wasn’t until that moment, overwhelmed by a primordial need to sow his seed, that he fully comprehended what she’d become - his mate. Relaxing his jaw and pulling away, he released her arms, clutched her head, and drove his tongue into her maw.

Acting as a depository for his essence, while he heatedly made out with her, did Bloom in. She’d somehow managed to endure their prior sessions in the bedroom, barely staying conscious, but this time felt different; the vehemence with which he used her, coupled with the final kiss, was too much to bear. Slipping into the welcoming embrace of euphoric oblivion, while her gut bloated with the sheer volume of his cum, she blacked out.

Mac would have continued frenching her, had she not collapsed beneath him. Unceremoniously unsheathing herself from his still pulsing shaft, she crumbled to the floor at his feet; the jarring development ripped him from his stupor and left him speechless. Staring down at her, seeing the final shots of his load coat her back, face, and mane, he stooped down, gathered her up, and turned to the restroom.

Any traces of exasperation were gone, replaced by a sublime feeling of contentment. He’d never been able to stay mad at her, yet this was a particular case. If he’d known that she would be as committed to him as she was, they would have probably been fooling around much, much sooner - after she’d become of age, of course. Holding her to his chest, stepping into the bathroom, he smiled and shook his head.

He’d just made even more work for himself, making one heck of a mess while still needing to repair the damage in her room, but those were relatively trivial concerns - for the time being, he needed to clean her up and get her into bed for a well deserved nap. As he stepped into the shower, having set the water to wash over them, he made a mental note to visit Ms. Cheerilee and explain Bloom’s absence.

Though he couldn’t quite wrap his head around why being called Daddy had flipped some switch within him, he couldn’t deny how arousing the moniker was. Grabbing the shampoo with one hand, hoping he wasn’t developing a new kink, his eyes wandered to her cum-bloated belly. At the rate they’d been going, having unprotected sex on a daily basis, he wouldn’t be shocked if he’d unintentionally put a bun in her oven. Caressing her stomach, unaware of just how effective Zecora’s potion had been, he had no way of knowing just how right he was…
