Helpful Sister

Droplets of sweat trickled down Big Mac's hide as he walked underneath the heat of the scorching summer sun. A cart full of freshly-gathered apples rolled behind him, his muscles tense and bulging under the heavy load. Despite it, the stallion's face looked almost relaxed, as if he barely even noticed the weight. Step after step, he steadily approached the barn.

Sugar Belle was silently enjoying the sight of him. Something stirred within her when she watched him so casually driving the load that she herself could hardly move at all. Mac's strength was unparalleled – it made the mare feel warm inside knowing that she had such a prime stallion all to herself. For her, simply watching him work his muscles was pure pleasure.

She saw sweat gleaming softly upon his burly naked chest, his discarded shirt hanging across the cart's sideboard. A simple straw hat protected his head from sunlight, shading his face and neck.

Belle's gaze lowered down to his jeans, her eyes focusing on the fat bulge at his crotch as they were often prone to do. Big Mac wasn't even hard, she knew, yet his cock left an unmistakable imprint on the fabric of his pants. His size was honestly intimidating – she both admired and feared it. Even after many months of being happily married, they still hadn't moved past handjobs and blowjobs. Belle absolutely loved worshiping his cock, but the thought of letting that massive thing penetrate her tight pussy always made her feel uneasy. Big Mac was nothing if not understanding, of course, but she still remembered that desire to ravage her burning within his eyes whenever she sucked him off.

"Need some help unloading those apples, dear?" Belle asked as he drove the cart past her, moving to walk by the stallion's side.

"Oh, ya don't need to worry about that, Sugar," Mac answered.

"I have to insist, hehe." The mare casually groped his crotch, looking at the stallion with a naughty smirk. "I've been watching you work for a better part of an hour, doing nothing myself. My hands are itching to get something done." She placed a loving kiss on his cheek.

Big Mac looked at her face, then down at the generous cleavage of her yellow dress. She felt a throb pass through his shaft underneath her hand and leaned forward to give him a better view, shaking her chest. Belle had a big, squishy pair of tits, and she quite enjoyed using them to tease her stallion. With no bra to hide them, Mac even got a nice peek at her dark purple areolas.

He turned around for a moment, finding his sister between the orchard trees off in the distance. She was filling up the buckets with apples that had fallen from the trees she'd bucked a few minutes ago, wholly consumed by her task.

"Let's go then."

Big Mac quickened his step, pulling the cart forward with a short grunt. Belle's lips spread into a wide, lecherous smile as she sped up with him. She walked even faster than him, in fact, advancing in front of the stallion to give him more space. A naughty thought suddenly entered her mind and she quickly acted on it – her hands pulled up her dress, exposing the bottoms of her thick asscheeks to his gaze. When she looked back at him, she was happy to see that his sight was directed exactly where she wanted it to be, though he almost immediately raised his eyes back to her face. Belle just blew him a kiss and pulled her dress even higher, the naked cleft of her fat, pink butt making it obvious that she wasn't wearing any panties. The mare preferred to dress lightly in such hot weather, and if she could tease her stallion with it then so much the better. She was sure the sight of her exposed rear was just the thing to lift Mac's spirits during his work.

Belle lowered the dress back down, hiding her bubbly cheeks, but after a few seconds raised it up again, teasing her stallion with tantalizing glimpses while he walked behind her. As they approached the barn doors, she ended the show with a sensual squeeze of her ass and entered inside. Big Mac followed her, hauling the cart over to a large stack of empty crates and bringing it to a stop.

He removed his hat and wiped his brow, while Belle watched him from the side. She'd raised the front of her dress to give Mac a little surprise when he turned to her and was silently waiting for him. The naughty mare wasn't left disappointed – Big Mac ears rose up and his face flushed as he noticed Belle exposing her pussy. She had no doubt that his fat cock twitched inside his pants too. His bulge was already visibly larger than it was before they'd entered the barn, the mare's tongue pushing a bit from between her lips as she measured it with her gaze. While Mac made a point of not staring too much at his fiancee's naked parts, she didn't even try to hide the fact that she was ogling the swell within his pants. Her eyes drilled into his crotch, which made Mac feel even more awkward than before.

Sugar Belle knew that he was quite self-conscious about his size, never able to hide the thick shaft he was blessed with, especially when he was aroused. For a shy stallion like him the idea of publicly displaying his erection was seen only as a constant source of shame. It was so incredibly unfair, Belle thought, that her husband would be embarrassed about something he could not control, maybe even something that he should be proud of instead. She'd never missed a chance to show her affection and desire for his massive cock, hoping to break through his mental barrier.

At the same time, she couldn't deny that she enjoyed teasing him. She loved seeing his embarrassed expression when she gawked at his obscenely large bulge. But it was only because she was aware that deep down some part of him actually liked it, even if he was still too closed-in to fully show it. Belle wanted to embolden that prideful, perverted part of him and let it run wild.

"Come here, love~" she purred. "I wanna see your big hard cock from up close, wanna feel its weight upon my face." Her fingers touched her pussy, giving it a slow, sensual rub. She let her bright yellow dress fall back in place and beckoned him closer with her hand.

Big Mac approached as if pulled by a string. His eyes roamed her body, stopping for a few seconds on the breast she had playfully uncovered for his pleasure. Large and heavy, it would've sagged down if not for the taut fabric of the dress keeping it up from underneath. Conversely, the weight of her gorgeous round tit pushed the gown even further down, threatening to expose the second mound of flesh as well. Mac wouldn't mind if that were to happen, Sugar Bell supposed, so she deliberately jiggled her breasts before him, leaving it up to a chance if he got a better view. But even with the added pressure of her unveiled boob, the dress managed to hang on, if just barely. The cloth caught onto her thick nipple, exposing a good half of her areola and most of the pink tit-flesh in process, but leaving just enough outside of the stallion's view to keep him mildly unsatisfied. Belle smirked, letting the dress remain in its precarious position.

"Honey, can you help me out? I think this dress is a bit too tight," the mare said with a quick glance at her half-revealed breast. She even pushed her chest out, openly giving Mac the honor of fully exposing her fat mammaries. Her fingers brushed teasingly along the covered nipple.

The stallion came to a stop in front of her and raised his hand. His large palms made for a great fit to Belle's equally large tits, perfectly sized for getting nice handfuls of her soft flesh. But first, he simply curled his digits underneath the fabric of her gown and pulled it down with a slow, steady motion of his arm. Belle visibly enjoyed that, seemingly even more than he had. That's what she might've thought if she hadn't already placed her hand on top of his bulge, feeling its powerful throbs. Mac's face often hid his emotions, but she could always count on his cock to tell the truth. Another reason why she loved it so much.

Big Mac didn't need to be invited to help himself to her breasts and his fingers were sunk into her mounds almost as soon as the dress was down. A pleasured sigh escaped Belle's mouth as she let him enjoy the pliable softness of her tits. She knew how much he liked to grope them, how quickly his cock filled with blood when he squeezed them between his meaty fingers. No matter how hard he grasped them, she never told him to stop. And it wasn't like Mac would ever knowingly squeeze them too much anyway – he was always so tender and careful with her, constantly in control of his great strength. Only occasionally did his restraint slip, making his hard grip elicit light pangs of pain in her chest. But Belle didn't mind. Honestly, she even kind of enjoyed that. It pleased her to know that sometimes he had so much fun cupping her tits that he would lose control.

"You really like 'em, don't you? My big, fat boobs," Belle asked the stallion.

"Eeyup."

"Wanna suckle on 'em, love?" She shook her soft milkers.

"Mhmm."

The stallion moved his head forward. But before he could place his lips on her dark nipple, the mare unexpectedly pulled her chest back, an impish smile on her face.

"A-ha, not so fast!" she playfully chided him. "First, I would reaaaly love if you told me how great they are, in that sweet, deep voice of yours." Belle leaned forward and brushed her lips across his, their noses rubbing. "Then you can play with my tits all you want. And with my ass too, mwah."

Big Macintosh answered the little kiss, pursing his lips at the same time. As his wife pulled back, he was silent for a few seconds, his gaze first directed at her tits and then moving up to look straight into her eyes. Suddenly, Belle felt his strong hands clamp down on her thick rear, scrunching the dress under his fingers as he pressed them deep into her flesh.

"Yer breasts are incredible, Sugar. I wanna lick 'em all over." He said, kissing her passionately. His arms pulled her up by her ass, making her rise onto her toes.

A pulse of lightning shot through Belle's nethers. Mac's pleasant baritone made her ears tremble as she awaited his every next word with trepidation, desire filling her up.

His mouth moved to her chin, then down her neck and to her beautiful, heavy bosom. He was bigger and higher than her, so Belle was forced to tilt her frame back to give him better access, wrapping her hands around his torso while he held her up by her fat, bubbly buttcheeks. She could feel his giant cock pressing into her crotch, its succulent shape evident even through the clothes. Her thighs pressed closer, trying to get as much contact with his bulge as possible.

Mac sucked Belle's titflesh into his mouth as he moved his lips across her chest. Every time he released it, she could hear a plump smack. And when he wasn't peppering her tits with amorous kisses, his tongue was circling her areolas, licking her nipples, tenderly flicking the stiff little nubs.

In response, Belle left loving smooches on his forehead – the only place her lips could reach. "I love you, Mac," she whispered. "You know just what I need. Fuck… I wanna suck your huge cock so much."

Belle spoke from the heart. A perverse desire to hug Mac's dick with her mouth always filled her up whenever he pleased her. And not just when they were intimate, but even after something as simple as helping with her chores. She didn't know if there was something wrong with her, or if that's just how a mare's brains were supposed to work, but she never resisted that desire. Why would she, when it made her dear Mac so happy to fulfill her wishes?

Belle let the stallion nuzzle and lick her teats to his heart's content. He'd pressed his head between her breasts and had the mare squeeze him from both sides for good measure. After that, he pulled back with a smile, left a pair of loving suckles on her tits, and finally let go of her ass. Meanwhile, Belle was already itching to start pleasuring his cock, smacking her lips as she remembered its musky taste.

"My turn now, honey," she said with a wink. Her hands ran along his chest as she squatted down, coming face-to-bulge with him.

Even inside his pants, it looked so gosh darn tasty that she instinctively licked her lips. Without a moment of hesitation, Belle pushed her face into it, rubbing her nose across the obscene protrusion. The shaft underneath was firm and throbbing. Its heat seeped through the fabric, and so did its smell. When she pressed her muzzle into the bulge, the potent male scent passed through her nostrils, making her want to lick the thing all the more. Sugar Belle didn't restrain herself and soon her tongue was leaving a wet trail upon the fabric. The coarse texture didn't bother the mare – it would only make the moment when she samples Mac's cock directly that much more pleasant. Moreover, she enjoyed the subtle depravity of the act. Running her tongue along the stallion's length through his clothes somehow seemed even more perverse than doing it normally. Maybe because such a gesture served little purpose beyond demonstrating the depth of her devotion to worshipping his massive tool? She loved Mac's cock so much that even licking it through his pants was enough to make her pussy wet. There was no need for her to play up her pleasure – a lewd smile spread out across her lips all on its own, her eyes shining with joy when she looked up at her stallion.

Soon, Belle was dragging his zipper down and undoing the button that kept his jeans up with a practiced motion of her hands. After a little pull, Mac's pants fell down, leaving his cock covered only by his light-blue boxers. The underwear strained under the pressure of his massive package, stretching out so much that a gap appeared above his pelvis and two more between his thighs. If Belle stood up and looked at his crotch from above, she would be able to get a nice glimpse of his red cock and his thick, round balls.

But there was no need for it now as the soft fabric already gave his bulge a very distinctive, evocative shape. At this point, his underwear did little more than enshrine the tool within – there was simply no concealing that behemoth. Belle could even see an imprint of one of his dickveins on top of it. She ran her finger along the subtle protrusion, checking that her eyes weren't playing tricks on her, and then double-checked it with her lips. She could already taste his flavor.

There was a dark spot in the fabric at the end of the tubular shape, right where Belle knew his cock-slit must be. She rightly guessed that the musky taste would be even more powerful there, a few laps with her tongue successfully confirming the hypothesis. The mare even suckled on it for good measure.

As a bonus, Belle got several breaths of Mac's cock-stench. The smell was much stronger than when it was filtered through his pants but that was still not enough for her. Like an addiction, a small dose only made her crave for more. She pushed her muzzle in the underwear's gap near his thigh and took a mighty whiff of the stale dick-air underneath. Her nostrils flared as Mac's densely-packed musk shot through the passages, for a moment completely overwhelming her. She almost looked drunk when she raised her eyes up. There was an absent, blissful look upon her face, her eyes unfocused, as if she barely even saw the stallion beyond the musky haze that filled her brain.

"You alright there, Sugar?" Mac inquired, carefully placing his palm onto her head and giving her a few affectionate rubs.

"Feeling better than ever~" Belle moved in rhythm with his motions. She was in love with the weight of his strong hand on top of her skull. "Will you do me a favor, honey?" The mare kissed his bulge and looked up, fluttering her eyelashes at him. "Press my face into your crotch, pretty please? And then drag my muzzle all across your fat cock."

What an invitation! Belle knew the stallion wouldn't be able to resist it. Her eyes lit up when she felt his grip harden on top of her scalp, and a second later, she received a nose-squishing faceful of his swollen dick. Mac's other hand joined the action too, and he began rubbing her muzzle into his junk, just as she asked him. Blessed Celestia, it felt so damn good to be used by him, to let him take control and have her face serve as his personal dick pillow.

"Don't even worry about me, love, just use my face to pleasure yourself!" Belle goaded him on as she licked and kissed his shaft, demonstrating that she was enjoying herself just as much as he was.

It didn't matter to her if he was a bit rough. Belle definitely preferred that to him trying too hard to keep her comfortable to the detriment of his own pleasure. Cock-hugging sluts like her weren't supposed to be comfortable anyway. Her purpose now was only to serve as a target for his lust. Belle's face was a soft, warm pillow that a strong big-dicked stallion like her dear Mac simply deserved to hump and squish into his crotch. As an unashamed size queen, there was no bigger honor for Belle than to be pressed forcefully into his thick erect cock, made to bear its imprint upon her muzzle. It was in the moments like these when she truly understood just how fucking big he was, as that fact was literally rubbed into her face.

Oh gosh, she was already dripping and Mac's fuckrod wasn't even out yet. It won't take long now though. After all this teasing, the only thing left for Belle was to finally suck the damn thing. Both her and Mac clearly yearned for that. Those needy throbs underneath her smooshed nose were evidence enough that the stallion's dick was primed and ready to be licked all over.

As his grip began to relax, Belle moved on to the next stage of her plan. She grabbed the hem of his boxers with her teeth and began pulling them down, her hands staying wrapped around his knees. It took some struggling to tug the stretched garment around Mac's huge cock, but Belle was nothing if not persistent. The difficulties made the moment when her stallion's heavy shaft finally sprung out of his underwear only more rewarding. As it happened, her eyes followed the cock's ponderous wobble with fascination. And when Mac's shaft throbbed, jerking up before her, Belle felt a pang of lustful pleasure run through her wet cunt. Precum flooded out of his slit, trickling down the crowned head of his cock in translucent, syrupy rivulets. There was only one thing missing from that beautiful image – her lips, wrapped around the stallion's tip.

Sugar Belle looked up at Mac, opening her mouth wide and pushing her tongue out with a seductive, deliberate slowness. With her lips placed right in front of the stallion's glistening tip and her eyes fixed upon his face, she presented him with an invitation in the form of a few short, steady nods and a quick glance at his crotch. Her warm breath tickled his cockhead, teasing him with the pleasure that required only a small push of his hips.

Big Mac sunk his tip into the mare's pretty mouth, its humid heat surrounding the most sensitive part of his cock. Inside, her tongue lapped on the slick, salty flesh like it was the world's tastiest popsicle. But for Belle it was even better than that. Caramel sweetness had nothing on the intoxicating taste of raw masculinity that Big Mac's cock was positively drenched with. Some mares would be overwhelmed by a single lick of his potent pre, others might scrunch their muzzles and simply persevere, but Belle truly loved it. She reveled in the sour, tangy flavor, in the brain-melting stench of his throbbing horsecock. The taste of his sweaty, musky skin and his copious precum inside her mouth had combined with the dick-infused air coursing through her nostrils, leaving her senses under a constant barrage of the overpowering male essence. And Big Mac hardly even needed to lift a finger. The mere presence of his towering, musclebound body and his thick cock was enough to make Belle fall on her knees and worship him. Feeling the taste of his dick wash through her mouth and seeing the joy on his face were the only rewards she needed for her devotion.

After gleefully swallowing all of Mac's pre-ejaculate, Belle pulled her lips away with a wet pop. Her tongue swirled a few times around the spongy ridge of his cockhead and then she moved her head along its side, cleaning the stallion's dick with her spit. There were so many delicious inches of cock in front of Belle that it seemed like she could just slide her lips endlessly along its surface and hardly ever touch the same spot. If it really was a popsicle, it would've certainly held enough sugar to send a grown pony into a coma.

Luckily, the worst side effect that Belle ever suffered from sucking too much cock was her developing addiction to it. The more she licked and worshipped Mac's massive fuckrod, the more she grew in love with it. She became so used to his huge size that she wasn't even sure if she could ever really appreciate a smaller cock in the same way. A regular stallion's genitals would make him look like an underdeveloped teenager next to Big Mac, as Belle well knew from her previous experiences. The idea of ever going back to those seemed almost incomprehensible to her. After spending so much time feasting her eyes on Mac's breathtakingly huge cock, all others would seem undersized and even diminutive in comparison. With each day that conviction grew stronger inside her, while her mind embraced Big Mac's package as a definition of what a real stallion's dick was supposed to be like.

Belle never even tried to force her thoughts to go in the opposite direction. She happily accepted the new paradigm and deliberately entrenched it deeper within her mind. Maybe she was subconsciously compensating for Mac's own timidness in regards to the size of his cock, or maybe she was simply that much of a cock-craving size queen all along, but the idea of becoming so committed to his giant dick that she would stop even being aroused by the average-sized ones was itself surprisingly arousing. Especially so when she was in the process of marveling at and worshipping Mac's breeding tool. Just picturing other stallions squirming and turning their eyes away in the presence of Big Mac's superior cock made her pussy flutter. Mac himself was too kind to enjoy subjecting other ponies to such a humiliating experience, but Belle was gonna teach him to appreciate his gift eventually.

For now, spreading spit around Mac's shaft with her tongue was enough to keep him happy. It wasn't an easy job, pleasuring such a big cock, but Belle had plenty of experience by now. She used both of her hands to pump it at the same time as she left long broad licks on its surface. Her plush pink lips occasionally traced the bulging veins, kissing and suckling the stallion's lifelines, paying particular attention to the thickest one on the top. She never missed a chance to lap on Mac's medial ring as her mouth passed over it, or to slurp up a fresh batch of precum from his tip.

His big, jizz-heavy balls weren't left without attention either – Belle knew how important it was to scratch the stallion's itchy orbs with her tongue, especially when they were full and sweaty. Mac's balls were so huge she was sure he could suffocate her between them if he pressed her face into his nutsack.

That'd be pretty hot.

Belle mulled the image over in her head, swallowing his ball-sweat and replacing it with her drool. She definitely wouldn't mind being smothered by her husband's massive cum-pouches for a little while. In fact, she was already digging her nose deep into his sack even without his help, and it felt absolutely amazing. The smell, the taste, the soft fuzzy texture – she loved all of it. And most of all, she loved feeling his jizz churn within the testicles. That thick, potent liquid was so damn close to her face, yet still not close enough, teasing her with a future spunk shower. It was difficult not to think about it when she licked his balls – Mac's orgasms were big and explosive, as befit the size of his package. One could hardly ask for a better finish. Getting completely covered with his cum always made her feel like she'd won a spunk lottery, much unlike the few measly spurts of jizz that other stallions would provide.

Belle never knew what it felt like to have thick rivers of seed descending down her face and body before she'd hooked up with Big Mac. Now, she couldn't imagine it any other way. Receiving a one-man bukkake from his cum-hose of a cock was an experience that every slut would be craving for, if only they knew what they were missing. Luckily for Belle, his tremendous loads were reserved only for her, which made them feel all the more special. The least she could do was to reward his hard-working testes with sloppy kisses and suckles, encouraging them to give her the biggest batch of Mac's nutjuice possible.

Still, after the many times Belle had been covered by his jizz, thoughts of going further than that were finding fertile ground ever more often within her mind. While her fur had been dampened by Mac's spunk numerous times, her lonely pussy never got to feel that gooey warmth spread inside it. Just like it had never felt the immense pressure of his magnificent cock. This was something she'd long sought to correct, yet the dread of what his massive bitch-breaker might do to her tight cunt always kept her from going through with it.

Belle pulled her head back from Mac's sparkling-wet balls and sized up his length with her gaze, contemplating if she was actually ready for it. This wasn't the first time she had seriously considered letting him fuck her pussy, but now she felt more confident about it than ever before. She imagined how great it would be to finally cross that barrier and let the stallion claim her, once and forever! There will be no going back once he stretches her pussy out with that monster.

The thought of taking his fat cock inside of her didn't intimidate her as it used to. On the contrary, the sight of his shaft, its taste lingering inside her mouth, filled her with an almost religious awe. Fear and worship always went hand-in-hand, after all, one channeling into the other under the right circumstances. Just like the first ponies revered fire all the more for the terror it induced, so did Belle devote herself to Mac's stallionhood with greater passion for every anxious shiver that it sent through her crotch. Months of worship and adoration had left their mark upon her psyche and now Belle's cunt was begging to be ravaged by the very cock that it feared most.

She pushed a hand under her dress and rubbed her clit while her eyes traced the stallion's thick, twitching, spit-covered dick. Fuck… she wanted it inside her so damn much. More heat spread through her body with every second Belle spent looking at his cock and imagining it piercing her folds. She really was going to ask him to destroy her cunt right here and now, wasn't she?

Lightning surged through her nethers and she almost came on the spot just thinking about taking Mac's length inside. Marejuice poured down Belle's thighs, her pussy demanding to be obliterated by his cock in the only way it could. She raised her hand up to her face and studied her wet, sticky fingers. That's when Belle knew for certain what she was going to do.

"Honey…" the mare spoke up, looking up at Mac. Her voice trailed off as she gathered herself, leaving the pair in silence for several seconds. "Can I ask you something?" She continued and then kissed the tip of his cock, for a moment placing her lips in a seal around his drooling slit.

"Eeyup." The stallion's cock throbbed in time with his answer, which Belle found strangely endearing.

"Do you want to fuck me?" She asked, pumping his dick with both of her hands and swirling her tongue around his cockhead.

Mac's expression grew surprisingly contemplative for such a simple question. He didn't seem to be sure what exactly Belle had in mind. "Ya mean… fuck ya how?" he asked back.

"Fuck my pussy. You'd like to do that, right? Just tell me straight, love."

"Ehm… Ah…" Mac stammered out, at first trying to come up with a thorough answer, but eventually caught himself and resorted to a simple "Eeyup!"

Belle smiled. "Let's do it now then. I'm ready. Just lay me down on one of those bales and pound me into it. How about that?" She nuzzled his cock and stared up into his eyes.

"If that's what ya really want, Sugar..."

"I do, Mac. I do." The mare nodded, rubbing her cheek across his shaft. "I'm so fucking addicted to your cock." She glanced at his tool with an expression of pure adoration.

"I don't even care if it splits me in two. This thing is going into my pussy and it's going in deep. You'll ruin me so hard no other stallion will ever be able to satisfy my needs… and I'll love it."

Big Mac was taken aback by her confident statement. To be honest, Belle was taken aback by it herself. But she wasn't going to go back on her words, however rash they might be. The mare knew that if she didn't exude confidence, Mac would never agree to do those depraved things she wanted him to do.

Her actions definitely had the desired effect. The stallion didn't say a word, but he didn't need to. He simply brought his arms forward, letting Belle grab onto them and helping her get up on her feet. They hugged and mashed their lips in a sloppy tongue kiss, with Mac's huge cock squeezed in between the mare's thighs. Half a minute of spit-trading later their muzzles separated and Belle stepped back. With a quick look around, the pair made their way to a more suitable spot for their deed.

Belle felt panic creeping in as Mac's cock refused to enter her folds yet another time. The stallion pushed his hips forward but his tip simply slipped by her pussy, only grazing the wet entrance with its girth. Lying on a big, soft bale of hay, she spread her legs as far apart as she could, yet that still wasn't enough to provide a fitting opening for Mac's massive cock.

"Come on… why does this have to be so difficult!" the pink mare exclaimed in frustration. "We've gotta be doing something wrong…"

The two have been trying unsuccessfully to initiate the penetration for a good ten minutes. Belle had expected that it could be challenging, but she did not anticipate that they wouldn't even be able to pass the first hurdle. Now that she stared at Mac's broad cockhead next to her tight cunny, it was becoming obvious how naive she had been. That thing was way too huge to fit inside her without thorough preparation.

"Ah think mah trunk is just too big. Sorry, love." Mac turned his head away in shame, slowly pulling his dick back. "Maybe Ah will just lick ya out instead?"

Belle wasn't taking any of it. After all the emotions that ran through her head, surrendering now was simply not an option.

"Just keep trying, honey!" she encouraged her stallion. Her pussy was aching for his fat throbbing fuckrod, slick with its natural lube and burning hot. Belle was at the peak of her excitement, ready like never before to let Big Mac subjugate her cunt. How could she allow such a chance to slip through her fingers?

The mare grabbed his shaft and rubbed the tip across her folds in the hope that that would ease its passage. But Mac's thick crowned glans did little more than tease her pussy. She couldn't even call it pleasant. This was simply torture! At any other moment, she definitely wouldn't mind having his dick slide across her juicy snatch, but now it just felt like the universe was taunting her.

"Damn this huge useless slab of meat," Mac muttered sourly. "AJ has it so much better."

"Don't worry, love, we'll get through this. You've got the best cock in the world. I wouldn't trade it for any other!" Belle responded with passion. She couldn't let her husband wallow in shame for his big beautiful dick. It was an incredible thing, an object of envy for all other stallions and their mares, and she was going to prove it to him. Though, right now, they might actually need some assistance.

There was no shame in seeking help, right? Big Mac's comment about Applejack led Belle to contemplate on an unusual thought.

"Maybe we could ask your sister to lend us a hand?" She wondered aloud.

In many ways, Applejack was a mare just like Belle – spunky, pretty and energetic. But there was one thing that definitely made her different, and that was the sizable cock hanging between her legs. It wasn't as big and prominent as Mac's, but it was still large enough to leave an obvious protrusion in her pants. And unlike her brother, Applejack was not ashamed to openly display her bulge to every passer-by. It even seemed like she was deliberately choosing to wear tight-fitting clothes on her lower half, making the evocative contours of her cock stand out all the more. Belle hadn't had the pleasure of witnessing Applejack's package without a cover, but her educated estimate suggested that the mare definitely had the equipment necessary to help them. Her cock was thick enough to give Belle's tunnel a nice stretching, but not so thick that it wouldn't even fit.

"Ah don't know 'bout that," Mac glanced at the barn's doors. The stallion kept himself composed, but Belle knew him well enough to see a whirlwind of contradictory emotions in the small movements upon his face. "Would ya really be okay with AJ joining us?" He asked her in turn. It was clear that he wasn't even sure if he himself was okay with it.

"I would. Applejack has been nothing but kind to me. I think she really cares about our relationship. If there's anyone that can be trusted with this, it's her," Belle laid out her case. She continued to absentmindedly grind Mac's cock across her folds with one hand, while stroking her clit with another.

The stallion sighed. "Ah guess…" For a little while, he simply contemplated quietly, and Belle let him do so. This was a deeply personal matter, obviously, doubly so because it involved his sister. Big Mac loved the farm mare to death, but that didn't mean he would be perfectly comfortable with her fucking his wife.

"Ah suppose we could do that, as a very last resort," he continued, scratching his temple. "But we gotta try everything we can on our own."

Belle nodded. "Sure thing, honey. How about we also switch things up a bit?"

The mare guided Mac to lay on his back while she stood above him and began lowering herself onto his erect cock. She gyrated her hips, grinding her pussy on the swollen tip, still thinking about Applejack. The images of her succulent bulge were stuck in Belle's mind, the memories reinforced with every pleasant pulse that ran through her nethers. She remembered one pair of blue sporty shorts that Mac's sister had worn with particular fondness. They were sewn and tailored by her close friend and the town's fashionista – Rarity. Or so Applejack had boasted. She'd claimed the unicorn had done so as a gesture of gratitude for her help, but did not specify it further. Instead, she winked, leaving Mac blushing and Belle standing confused.

Those shorts had a peculiar quality that made them quite unique. They were constantly tight around Applejack's crotch, even when the mare was soft, yet could easily stretch out much further to accommodate the great size of her erection. Her cock's powerful form would always be displayed with mouth-watering definition, the meaty tube accompanied by a pair of fat, apple-sized orbs. If Belle wasn't already in a relationship with Big Mac, she might've just found her face glued to that obscene dick-shaped bulge after the first suggestive look Applejack sent in her direction.

Mac's cock was still a superior one of the two, of course, but Applejack's girth was not something to scoff at either. She had a confident demeanor around her, sometimes bordering on shamelessness, and that pulled on Belle's strings in all the right ways. A more manageable size of her shaft could also be of benefit, now Belle understood that more than ever as she tried fruitlessly to pierce herself with Mac's massive cock. She did feel a bit guilty thinking in such a way about Applejack while she was on top of her husband, fingering herself and rubbing her cunt across his dick. But it was his sister, not some other stallion, so it wasn't like Belle really did anything wrong by fantasizing about her, right? Now that Mac had agreed to the possibility of extending an invitation to Applejack, however cautiously he did so, carnal thoughts about her were on the table, as far as Belle was concerned.

The mare whistled, her heels digging into dirt as she made her way through the orchard. She casually scratched her crotch, looking around from below the shade of her cowboy hat. Her brother was nowhere to be seen, even though he was supposed to return with an empty cart long ago. It wasn't often that Mac lagged behind on his duties, but with Belle being around, Applejack could understand how he might've been delayed. That was one fine lass for sure, and even such a stoic stallion as her brother couldn't remain unmoved when she directed her charms at him.

Applejack still needed that cart though, or else the work was going to stall completely. She had filled up every available container with fresh produce, and now there was nowhere to empty them. If Mac was busy, she had no problem handling it on her own, but she would've preferred if he had notified her beforehand.

Eh, it's not a big deal. He can go have some fun with Belle.

Applejack wouldn't nag him for something so minor. It would only take several minutes for her to pull the cart herself anyway.

The heat of the sun didn't bother her much as she unhurriedly made her way to the barn. AJ was quite accustomed to it. She viewed the walk as an opportunity to rest and enjoy the slight soreness of her muscles.

That warmed-up lean mass was on full display, topped by her smooth orange coat and glistening with sweat. A green checkered shirt covered her torso, its raised sleeves revealing the mare's strong, beefy arms. Even where it hid her skin, the shirt couldn't prevent the bulging expanse of her tits from making its presence known. Those mounds weren't large enough to rival Belle's huge rack, but then again Belle sported one of the biggest pairs of tits in town. Applejack's bust was more than respectable for a laboring mare like her – any bigger and it would only serve to make her farm duties more cumbersome.

But while AJ had lost when it came to the amount of fat tissue on her chest, she had definitely reigned supreme when judged by the meatiness of her body and limbs. Just like her arms, her powerful legs had some real bulk to them, decked with thick, skull-crushing thunder thighs. Quite a few of Equestria's villains had received a taste of those toned legs, having been bucked into oblivion. The visible definition of Applejack's muscles clearly suggested that she wasn't one to be messed with, and a big bulge inside her grey work shorts further confirmed that point.

After a few minutes of walking, the barn's entrance loomed over the mare. She swung the door open, wondering if she was going to find her brother inside. The cart was there, at least, that much she noticed immediately. It was still filled to the brim with apples.

Seems like Mac haven't even begun emptying it.

Applejack stepped inside, and her eyes quickly caught a flash of pink among the dull colors of the farm's instrumentary. Sugar Belle was at the back of the barn, her lower body hidden by the small fence that separated the building's sections.

"Hey, Belle! Have ya seen mah brother?"

Belle turned her head and gasped, tugging her sunny dress up. It confirmed Applejack's first-glance suspicion that the mare's breasts had been exposed, but she hardly even got a glimpse of those amazing dark nipples.

Rising on her feet, Belle hastily flattened the gown over her crotch too. Before she could answer, Mac's head appeared from beneath the fence as if he was lying under the mare, embarrassment heating up his face. The last time Applejack saw him this flustered was when she had caught him jerking his fat cock over a lewd magazine, years ago. The only thing she truly minded then was how softcore the pictures were, which is why she made sure to give him a pack of the naughtiest porn she could find in her stash on his next birthday.

"Hey AJ… Ya need the cart, don't ya? Sorry, we got carried away," the stallion quickly tried to explain himself. "Ah'm gonna empty it and roll it to ya in a few minutes."

Applejack's eyes sparkled with a strange kind of glee as she understood more and more just what the pair of lovers had been up to. She always had a penchant for bending sexual boundaries and her brother was well aware of that. Further intruding upon their privacy might not have been the most sisterly thing to do, but she just couldn't help herself.

"Haha, don't worry, Mac. Ah'll handle it myself, ya can keep doin' what ya've been doing," she said with a smirk. The cart was in the same section of the barn that Mac and Belle occupied, bringing Applejack closer to the pair as she casually strolled towards it.

The stallion was clearly trying to come up with some response, but this time it was his wife who got the first word out.

"Actually, we'd be really thankful if you could help us out, Applejack." Belle looked directly at the mare. The committed expression on her face spoke volumes about the nature of her proposal. So did the lengthy glance she gave to Applejack's groin.

The unexpected request almost stopped the mare in her tracks. Now this was mighty interesting; she couldn't allow such an opportunity to pass her by. She also saw her brother growing even more flustered than before. He glanced at Belle unsurely, then turned back to Applejack and delivered a cautious nod.

Applejack didn't need to think long on her answer. "Ah'm always happy to help the family," she assured the two of them, sauntering in their direction.

As she approached closer, Mac's body steadily came into her view. He wasn't wearing his pants, she saw, and a massive erection was bulging out his hastily pulled-up boxers. The corners of Applejack's lips rose up at the sight, her smile occupying a strange middle ground between friendly and lewd.

"So, whatcha need me to do?" One of her arms moved down to her crotch to give it a rather conspicuous rub. Just as she expected, Belle's gaze was instantly directed at the outline of her cock. Applejack's grey shorts were a bit too baggy to provide that skin-tight look that made every mare blush after a mere glance at her lap, but she still sported a pretty sizable bulge.

Belle was focused on AJ's crotch for a surprisingly long time, appearing to measure the package with her gaze. She raised her eyes after several seconds of staring, looking satisfied with what she saw.

"Well… me and Mac have got a bit of a problem. You're really the only pony we can trust to help us," the busty mare explained. "We've been trying to get intimate, but the issue is… I'm too tight for Mac to fit it in."

"So ya want me to fuck ya first? Stretch ya pussy out for mah big brother?" Applejack asked with a chuckle.

"Yeah… something like that. Your cock should be just the right size. Will you do that for us?" Belle inquired hopefully.

"Course Ah will! Ah would never let down mah brother."

Sugar Belle couldn't contain her joy. "See, Mac, I knew we could rely on Applejack. Wish I had a sister like that!"

"Now you do." AJ winked at her, melting the mare's heart. Her fingers tugged on the hem of her shorts, stretching the fabric out and then letting it snap back with an audible whack. "So, family, shall we begin?"

Belle's pussy began seeping anew from the moment Applejack agreed to help them. What a relief it was to hear those fateful words leave her mouth with such confidence and warmth. Belle had been terribly worried their first attempt at intercourse was going to end in a total disaster, but now the day was truly saved! How lucky they were that Big Mac had such an understanding, helpful sister!

That incredible mare was now behind her, aiming her thick orange cock at Belle's sore cunt, while Belle herself stroked Mac's shaft. The two of them had been losing their excitement as their attempts at penetrative sex continually failed, but Applejack had quickly reignited those lustful desires.

Well… Belle's lust was back in full swing, at least. All of her pent-up needs were once again gushing out of her pussy in an unending stream of sticky bitch-juice. But at the same time, it was clear that Mac still needed some time to adjust to his sister's domineering presence. That's where Belle was supposed to pick up the slack and make her stallion feel appreciated even if Applejack was the one actually sampling her quivering pussy.

Mac was seated at the middle of a hay bale in front of her, his thick musclebound legs standing at either side of it. The crunchy straw compressed underneath his heavy frame, forming a slight dent below his rear. He ended up looking at Belle from above since her face was now positioned at the level of his bulging abs. With her knees and feet on the ground, she leaned her upper body in his direction, reclining on the bale as she stretched her arms towards his groin.

Belle's soft hands ran the full length of his half-flaccid dick up and down, the rod quickly hardening once again within her grip. She gathered saliva and spit it out on his shaft, spreading out the translucent strings with her fingers. The stallion's expression remained somewhat conflicted, but Belle answered it with a lewd, beaming smile, overflowing with contagious joy.

And there were reasons for her to be happy, not the least of which was Applejack's cockhead scraping across her pussy lips. Though, after all the time Belle had spent doing the same thing with Mac, she really wanted Applejack to simply push it in immediately. Yet the farm mare decided to tease her even more. It felt different now though: instead of the gnawing distress she had experienced previously, this time Belle was sure the penetration was only a matter of time, growing wetter and hotter with each second Applejack refused to give her what she wanted so much.

"Just a few more seconds, sugarcube," the mare told her again and again. First, she was docking her cock, whatever that meant, then waiting until she grew fully hard, and now she was 'prepping the soil,' by squeezing out some of her fresh precum into Belle's opening, as if it wasn't already wet enough. Applejack had even dipped the tip of her cock inside, making sure Belle knew she could do it, but then pulled it back out and just continued teasing her. It almost seemed as if she was more focused on getting the most out of the opportunity, rather than on actually widening Belle's tunnel for her brother.

"C'mon, AJ, can ya finally fuck her?" the stallion said, his brows furrowed in mild dissatisfaction. He was clearly getting frustrated after another round of gratuitous postponement.

Applejack just laughed. "If that's what ya want, big brother…" She seemed to enjoy hearing him ask her to fuck his wife. Or at least, a heavy throb of her cock and a splurge of pre into Belle's pussy indicated as much.

Applejack teased the mare for a few more seconds, clearly not in any hurry even after Mac's outburst. But she did begin pushing her futa dick inside eventually. Mac kept staring at her, and even though Belle couldn't look behind she was sure Applejack stared right back at him. Was she remorseful or smug? That Belle couldn't tell for sure, but judging by the unmoved expression on Mac's face it was probably the latter. It definitely wasn't difficult to picture Applejack beaming with playful insolence as she steadily sunk her cock into her brother's fiancee.

And Belle didn't even have to imagine the mare's fat dick spreading her folds and the walls of her tunnel. Slowly digging deeper, it was insistently making its way through the tight, fleshy confines of her pussy. While Applejack's cock was not as big as her brother's, it was still by far the biggest one Belle had ever taken. The thing was thick as hell and could easily put to shame any other stallion. Just the sensation of it being pushed inside of her with the steady motion of Applejack's hips was already enough to send sparks of pleasure flying through her nethers. She was much more sensitive after the prolonged anticipation and that made it astonishingly easy for Applejack to bring her to the brink of orgasm. Inch by inch, the farm mare's homegrown horsecock was fulfilling Belle's instinctive need to be stuffed with something hot and throbbing. Her tender, over-aroused pussy has finally gotten that sweet satisfaction it had longed for.

Inside the overflowing wave of ecstasy, it was difficult for Belle to care about the stare-off between Mac and Applejack. But she still felt a tad guilty that her stallion was left out, so she made it a point to pump his massive cock extra-hard, kissing and suckling on it as well. That's where Belle's climax found her, the mare's lips pressed into her stallion's red, pulsing pillar, while Applejack hilted inside of her. It was Applejack's act of pulling back and then quickly slamming her hips forward that broke the dam and made Belle's eyes glaze over in orgasmic pleasure.

"Wow, Ah reckon ya wife reaaaally likes me, hehe."

Belle barely even understood what Applejack had said, feeling as though she was in a dream. The words kept ringing inside her mind, their meaning slowly crystallizing as seconds passed. Applejack was absolutely right, of course, Belle did like her a whole lot! But maybe saying it while she was creaming herself on Applejack's cock wasn't the best moment for such an observation.

"Sorry, brother, ya know Ah'm just pickin' with ya," the mare added, driving her cock in and out of Belle's tunnel. "Ya little sister is only gonna make sure this pussy is nice and ready for ya."

Applejack might've said that, but it was clear that she was taking on a much more active role than her simple task would imply. While her hips rhythmically spanked Belle's ass, her hands had already found their way on top of the mare's head. She dug her fingers into Belle's rich purple mane and pushed her face into Mac's dick, helping her to keep licking it despite the constant jiggling of her body.

Even if that felt a little rough, Belle was thankful for it, especially when Applejack began charging up the pace of her thrusts. She was totally ready to be pushed around like a cheap slut between the two siblings if that allowed her to keep pleasuring them both. There was no better gift for the curvy size queen than to have the pair of famed Apple-family cocks at either side of her. Long and thick, they were the epitome of raw, natural virility.

Belle was in heaven as AJ's powerful thrusts pushed her head deeper into Mac's crotch, first pressing her face into the base of the stallion's shaft and then into his huge, round, jizz-filled nuts. Even though Mac still remained passive, Belle was quickly becoming aware just how easily this pair of mighty ponies could wreck her with their massive dicks. The image of them truly spit-roasting her had infected the mare's mind and her slutty pussy immediately demanded that she make it a reality.

She pushed herself up, for a short moment unsuccessfully fighting against Applejack's tough arms, but very soon the big-dicked mare noticed it and relaxed her grip.

"Oh, pardon me if Ah was pressing ya too hard," she said with a guilty chuckle, slowing down her thrusts.

"No worries, sis. But I think it would be even better if Mac handled it." Belle raised her gaze up to the stallion's face. "Love, would you please help me suck your cock? I just really need a pair of big, strong hands to keep me steady."

It was absolutely impossible for Big Mac to deny her request. His inhibitions immediately surrendered to the combined power of Belle's charm, AJ's silent judgment, and his own overpowering lust. It was so easy to pull himself back and position the tip of his dick in front of his mare's mouth. The light bobbing of her head was already enough to make her lips touch his crown, welcoming him inside, into the hot, humid flesh-chamber, perfectly designed for pleasing big, hard cocks.

"Heh, ya better give the lass a good mouth-dicking, Mac. Ah think she fancies it rough and hard. Don't ya, sister?"

"Haha, I guess I do," Belle answered, herself not knowing for sure what she desired most. The only thing she knew was that her pussy rushed towards a second orgasm whenever she imagined Mac and Applejack hammering her from both sides. For a cunt-driven mare like her that was the only truth necessary to make her want to try it out.

"Aww, ya really are something special." Applejack gave Belle's scalp an affectionate rub and raised her hands. "Brother, ya know what to do." She winked at the stallion.

Mac's palms were bigger than his sister's, easily covering his wife's head ear-to-ear. His pinkies were as thick as Belle's thumbs and reached down to her cheeks, while his hands still remained in contact on the top of her head. Yet his grip was definitely lighter and more intimate. The tough, meaty fingers threaded softly through her locks, applying only as much pressure as was needed to keep her steady. She felt like she was in the palms of a gentle giant – vulnerable to him, but protected from everything else.

With the drooling tip of his cock already grinding on her muzzle, it was wholly obvious how she should reward him for the safety he afforded her. Parting her lips, Belle let him push his wet flared cockhead into her mouth. The familiar taste of his precum-covered dick seemed even more potent now. It had that delightful, soft texture of flesh topped by thick and sticky goo, becoming impossible to resist when enhanced with the heavy flavor of his musk. The flavor that was so incredibly addictive to any lustful cock-worshipping slut.

As soon as Belle's lips were wrapped around Mac's tool, the speed of Applejack's hips began rapidly increasing. Her movements weren't erratic – they followed a measured, well-trained pattern that had certainly been firmly established in the mare's brain. Applejack was pulling out almost the whole length of her cock before she would push it back inside, resulting in drawn-out motions and a slower rhythm. The powerful contractions of her muscles repeatedly sent her groin on a collision course with Belle's fat, wobbly rump, forming a steady beat of sex. Smack, smack, smack, it resounded through the barn, flesh hitting flesh, Applejack's cock burrowing deep into Belle's pussy.

But it wasn't enough for Applejack to simply grind her shaft across the mare's inner walls – her freed hands also demanded to squeeze something soft and pliable. Luckily, there was plenty of squishy flesh for her to choose from, starting with Belle's nice, meaty thighs. At first the double-teamed mare barely even noticed Applejack pressing both hands into the thickest parts of her legs. It was only after AJ had glided her hands up and down Belle's thighs, regularly sampling the softness of her lower limbs, that the wanton touches had truly registered in her mind.

Then Applejack moved her arms even further. Without any request or plea, she began groping Belle’s huge, supremely squeezable tits. And not in a light, cautious way either – her palms clenched greedily below the mare’s hanging breasts, molesting them harder than Mac ever had. It was good that the stallion couldn’t see what was going on there, or else he would have to bear witness to his sister’s fingers digging so deep into his wife’s softest flesh that they almost disappeared within. A rush of shameful joy shot through Belle’s nethers when AJ possessively groped her wobbling boobs. It felt dirty to enjoy it sooo much.

And while Applejack feverishly kneaded her tits, the stallion’s hands, in turn, massaged her head. He moved his fingers in circles on top of her scalp, as it was one of the few things he could do beyond keeping her from choking on his cock. Applejack’s powerful thrusts sent Belle’s mouth on a diving trip towards Mac’s crotch, but he always made sure that his huge shaft did not slip too deep into her throat. His efforts provided a delightfully comfortable dick-sucking experience, given the circumstances, and Belle was immensely grateful for that. Still, she couldn’t help but imagine what it would feel like if she let Applejack hold her head instead. The tough mare would’ve likely pushed Belle to her limit, making her choke and gag like a cheap throatslut on Mac’s dick. That idea had its charm, but Belle ultimately decided that she would rather keep Applejack’s palms on her breasts. Those greedy orange fingers served her much better over there.

“Yer one lucky stallion, brother, Ah tell ya what. If Ah had such a fine lass, Ah’d be balls deep inside her every gosh darn day!”

Applejack's sincerity made Belle’s cheeks flush. Neither Applejack’s tongue nor her hands hid the appreciation the mare had for the voluptuous body of her brother’s wife. At this point she had thoroughly groped Belle’s flesh, squeezing, pinching, and twirling the perky nipples between her fingers. Applejack had quickly become an all-around menace for Belle’s breasts, milking every ounce of pleasure out of the opportunity to play around with one of the biggest racks in Ponyville. And Belle loved every damn second of it, moaning around Mac’s cock while her love juice dampened the fur along her thick inner thighs.

But even Belle’s massive bust couldn’t keep Applejack’s attention forever. With every second, the mare’s appetites grew, and now her fingers were closing on Belle’s jewel – that hot, pulsing pussy that squeezed her cock so well. Sparks flew through Belle’s nethers when AJ suddenly rubbed her clit, the additional stimulation making her legs go weak. Her toes curled within her sandals while straw scrunched inside her clenching palms. Two sounds filled Belle’s ears – her own throaty moans and an ever swifter beat of Applejack’s hips against her ass. The long thrusts turned into rapid humps, Applejack’s breeding tool scratching every itch at once within her tunnel.

The only thing that stopped Belle from filling the whole barn with her cries was Mac’s cock lodged securely inside her mouth. She looked up at him with eyes wet from the intensity of the moment, seeing only a smudged picture of the stallion she loved most as her mind was wrecked by raw sexual pleasure. Her climax was approaching so fast she didn’t even notice it coming before it hit her with a full brunt of its carnal force, every muscle of her body suddenly growing tense and then relaxing just as quick in a wave of pure cunt-trashing bliss.

A deep cry of joy shook the air anyway, and Belle needed a second to understand that it was not her own. Behind her, Applejack bellowed so loud it put even the hardest of Mac’s orgasms to shame.

“YEEEEE-HAAAWW!” was the last thing Belle heard before Applejack pinned her down and filled her pussy with thick homemade nut-jam.

Hot, virile cum rushed from Applejack’s heavy balls straight into Belle’s unprotected womb, coating her inner walls in the sticky white seed. It felt so great that Belle didn’t comprehend right away just how far Mac’s sister had truly gone this time. The depraved pleasure overcame her good sense and she moaned even harder than before, enjoying the wet heat penetrating into her innermost core. Applejack’s swollen dick ejected her massive load with powerful, even throbs. Every second, it pumped more and more of her ultravirile futa jizz inside Belle’s fertile pussy, laying claim to her brother’s most treasured mare in an exceedingly perverse and treacherous manner. No doubt, AJ’s pleasure was all the greater and her load all the bigger for the utter shamelessness of her betrayal. Her nuts made sure to squeeze all the cum they could into Belle’s womb before poor Mac ever had the chance to stop her.

Brother's Right

All the color drained from the stallion’s face as he watched his nice, lovely, honest sister pour the contents of her balls into his wife’s pussy right in front of him. The light suction of Belle’s mouth on top of his own cock felt like a sick joke when contrasted with AJ’s unbelievably brazen act. To the last moment he couldn’t believe what was happening before his eyes, hoping against all hope that she was simply fooling around and only pretending to dump a fat load of jizz inside Belle’s womb. Unfortunately, there was no mistaking the relaxed expression of post-fuck bliss upon Applejack’s face – he very much doubted she could fake something like that. Only now, as her gaze fell lazily onto his displeased face, the realization of how much she’d offended him finally began reaching into her sex-crazed mind.

“Don’t tell me ya actually did it, AJ,” his voice sounded unnaturally soft. It wasn’t loud or angry, but it missed that spark of life that gave his speech its warm, friendly timbre. The only thing that separated it from being openly hostile was the tiny infusion of hope that things weren’t as they seemed.

“Oh, come on, brother, ya aren’t mad at ya little sister, are ya?” She dared to answer with a smile, but Mac’s expression only grew dimmer. As she pulled her cock out, her jizz began leaking out of Belle’s entrance, a few globs falling down to the ground with an audible splash.

“Applejack.” He looked her straight in the eyes. “What in Tartarus ya’ve been thinking? How could ya do me like this?”

“Ah… Ah didn’t thi…” She stammered out as a tsunami of emotions covered her face. Pain and pleasure, guilt and insolence, all mixed together upon it. “Ya didn’t say Ah couldn’t!”

The weak excuse didn’t impress her brother. “Did Ah really have to spell that out? Ya can’t understand on ya darn own that ya can’t just pump ya seed into mah wife?!” Mac felt his voice rising like it rarely had before. He couldn’t even remember the last time he was this enraged, and with his own sister no less.

“Honey, please… we can work it out,” a sweet, tender voice came from below. Sugar Belle’s orgasmic joy had already turned to worry, and now she was looking at her stallion with grave concern. “I’m sure Applejack didn’t mean to do it. She just got lost in the moment, didn’t you AJ?”

“Ahh… yeah.” Applejack looked down sheepishly. “Ah’m terribly sorry, brother. Ah don’t know what has gotten into me. It’s all mah fault.”

AJ was lucky that Mac had a massive weakness for his dear Belle. Just the sound of her voice was enough to bring his anger down. But it didn’t mean he was going to simply let his sister forget about her offense. His features relaxed, yet the fire still remained smoldering within him.

“Ya sure have a habit of testing mah patience,” he sighed, waving his head.

In response, Applejack allowed the corners of her lips to stretch up just a bit.

“Ah haven’t forgiven ya yet,” the stallion’s words quickly cut the movement short. “Ya’ll have to make it up to me, and not just with ya loud mouth.”

“What about mah throat then?” Applejack opened her maw wide and pushed her tongue out, showing off the view inside while her hand rubbed her neck. “Would that be enough to earn ya forgiveness?”

“Ah’m not joking, sis.”

“Ah’m not joking either. Big brother.” This time nothing could stop a playful smirk from running across the mare’s lips. Mac’s stern gaze was partially disarmed by his uncertainty of whether she had truly meant what he reckoned she had, while Applejack’s lewd, submissive gesture made his cock throb way harder than he expected. The thought of submerging his tool deep inside her mouth seemed surprisingly appealing at this moment.

But he had not time to dwell on that as there was a much more important matter for him to attend to.

“Do whatever ya want, AJ. We’ll handle it later. Right now, Ah’ve got a mare that needs mah attention,” He concluded, turning his head away from Applejack. The harshness of his tone showed that he would accept no continuation or contradiction.

Applejack stood back, giving her softening cock an occasional lazy stroke while Big Mac took his place on top of Belle. The mare was on her back now, facing him with a warm, slightly apologetic smile. It was clear that she felt guilty for enjoying Applejack’s jack-hammering so much, for cumming at the same time as Mac’s sister had. The stallion had indeed been filled with an uncanny mix of indignation, envy, and exhilaration when he watched AJ pound Belle’s cunt into an explosive orgasm before he ever had a chance to do the same. But he couldn’t be mad at her for liking it, or at his sister for giving Belle the pussy-smashing she deserved. Honestly, somewhere deep inside, he actually kind of enjoyed seeing it, even if he would never willingly admit it.

All the bad feelings would be easy to ignore, if only Applejack hadn’t carried it too far. She crossed the line he never expected her to cross and left Belle with a massive creampie, quite possibly impregnating her in the process. Now Belle’s pussy was filled with her jizz, and Mac could distinctly see and feel that as he pushed his cock inside. He contemplated draining Applejack’s cum before starting out, but that would require Belle to stand and wait until the spunk drooled out of her cunt, and Mac really didn’t want to subject her to that. It would just be an unnecessary, embarrassing distraction for all of them.

One thing that gave Mac some solace was that Applejack had really done her job well, stretching Belle’s pussy so wide that he now had no problems penetrating it with the giant round tip of his equally giant dick. Whatever else, AJ had always been a dutiful mare. The warm lube she’d so kindly added made the process even easier for Mac, though that hardly justified its presence.

The thick liquid slowly enveloped his cock as he pushed himself in deeper, forming a slick, gooey layer around his shaft. “Here ya go, brother, Ah’ve made it extra smooth for ya,” Applejack would’ve probably commented, if she hadn’t been wary of offending him. But now she didn’t even need to do it, as the mocking thought appeared inside his head all on its own.

“You’re so big, love.” It was Belle who had spoken instead, pulling Mac’s attention away from the slippery warmth of his sister’s jizz, if only for a few moments. The mare’s mouth hung open, her muscles stiffening as he fed more and more inches of his cock into her pussy. Even after Applejack had thoroughly ravaged her, Belle still struggled to adjust to Mac’s massive shaft.

“Ah’m gonna go slow,” he promised her.

“I know.” Belle wrapped her arms around his powerful torso. “I’ve wanted this for so long. Give me all you’ve got.” She kissed his lips, their tongues connecting for a brief moment.

Big Mac continued on. Periodically, he would pull his hips back just a bit, spreading out Belle’s tunnel with a few short thrusts and then pressing forward once again. The hot, soft walls of her pussy embraced his shaft, the delightful friction stimulating every submerged inch of his throbbing red flesh. And with Mac’s huge size all those inches quickly added up, as every one of them sent a continuous stream of pleasure into his brain. He wasn’t certain if the enormity of his cock would multiply all the sensations it received, but right now it sure seemed like that. Used as he was to getting blowjobs that covered only a small portion of his dick, the all-encompassing grip of Belle’s marehood made his cock feel absolutely divine.

But at the same time, it also made him all the more aware of the slippery filling that not too long ago had been inside his sister’s dark orange balls. This plentiful lube would’ve felt great, if only he wasn’t so inescapably conscious of its origin. The viscous liquid enveloped every bit of his cock-flesh, leaving its mark upon every sensation he experienced, constantly reminding him that Applejack had emptied her nuts into the pussy he was now fucking.

Luckily, even that wasn’t enough to overpower the raw pleasure of hilting his cock inside his mare. Neither did it seem to affect Belle. The happiness upon her face was all the reason he needed to keep going, her trembling moans rousing and energizing him. Her hands danced around his back, rubbing his muscles, pressing into his fur, while her fat tits served as nice soft cushions for his chest. They brushed across his pecs, stiff nipples rubbing across his skin. Underneath her breasts, her light yellow dress still remained upon her body, the fabric bunching up beneath her mounds and above her crotch, reduced to covering her middle section and nothing more.

Mac finally bottomed out inside Belle, the entire length of his shaft safely hidden within the stretched-out depths of her cunt. His big, cum-filled balls were parked next to her thick plot, their massive weight threatening the squishy flesh with a hell of a beating. Fortunately, Belle had more than enough fat in her cushy buttcheeks to soften the incoming blows. The stallion’s sack lagged behind the movement of his cock just a bit as he slowly pulled out half of his length and prepared for the next incursion. His shiny red orbs swayed softly underneath his crotch after he had stopped. But before they had the time to come still on their own, Mac pushed his hips forward and sheathed his cock once again, giving a light bump to Belle’s ass.

He began with slow, cautious thrusts, carefully studying the mare’s face for any sign of discomfort. With great girth came great responsibility, and his responsibility was greatest of all. Every little movement of his hips drove his monstrous cock through Belle’s tunnel with potentially catastrophic consequences. It would be so easy for him to completely ruin her, to break all resistance with a vigorous pounding he knew his hips could provide. But he would never be able to forgive himself if Belle had to endure such pain and discomfort when it was totally possible to avoid it. No matter how much his haunches wanted to fly forward and smash his dick inside, he kept control, steadily spreading out Belle’s pussy, preparing her for the time when he would finally let his natural instincts take charge.

In the meanwhile, the pair had plenty of space to rub noses and trade spit. Whenever Sugar Belle wasn’t suckling on Mac’s tongue, she was kissing and licking every part of his face her lips could reach, leaving little trails of drool across his cheeks, chin, muzzle, and even his ears. At the same time, she rocked her chest underneath him, rubbing her tits into his bulging muscles. Her huge breasts turned out to be just the perfect pillows for softening the stallion’s recline. Two big squishy milk jugs full of raw feminine appeal stood up against a steel-strong wall of masculinity descending upon them. They could only cushion and appease his hardened body, but never stop it. The power to stop was in Mac’s hands, and he utilized it with all the care that Belle had entrusted to him. Pinned underneath him, she was completely powerless before his superior might, his hulking frame restricting her movement to the bare minimum. Yet there was no need for resistance, as his mind and heart were already hers.

The pleasant softness of her body rubbing against his own made him all the more mindful of her comfort, especially when his hips began picking up pace. His thrusts grew strong enough to cause Belle to jiggle underneath him, creating even more friction between their closely-pressed flesh.

“I love you, Mac,” she whispered in between moans and labored breaths. “I love you soooo much. Nnngh…” Her hands trembled on his back as he plunged inside her. “I want you to make me yours. Want you to fuck my cunt so hard it’ll forever remember your cock. Will you do that, honey?“

“Yes, sugar.” He kissed her. “Ah’m gonna give ya a proper pounding.” A quick, hard thrust followed, emphasizing his promise in a way Belle would surely appreciate.

“Fuuuck… I love you! Do that again! Turn my pussy into a gaping mess! Aaaah!“ Her face contorted in pleasure, tongue lolling out and speech breaking off as her vocal cords let out the pent-up pressure.

Big Mac smashed his pelvis into her crotch with a pleasured groan of his own. Belle’s lewd words always brought up the most intense feelings from within him, the dirty suggestions giving him goosebumps when spoken in her angelic voice. It seemed so wrong for such crude things to come out from between those pretty pink lips, and even worse for such terrible, perverse notions to be nurtured within her kind heart. Yet that’s exactly what made his cock throb the hardest.

Now that Belle had given him the go-ahead to wreck her cunt, Mac could no longer stop his hips from flying back and forward with ever greater speed. He was picking up pace with every thrust, constantly keeping Belle on the very edge of her capacity to withstand the immense dick-pressure within her. His hefty balls swung like a pendulum and spanked her ass, again and again, each orb leaving an impact on her fat, wobbly rear.

The experience was so breathtakingly amazing for both of them that Mac almost forgot about the constant overshadowing presence of inordinate amounts of Applejack’s cum-lube. Unfortunately, that sweet obliviousness wasn’t meant to last. As if the feeling of her jizz sloshing around his cock wasn’t already enough, the loud squelches that followed his movements now added another demeaning stroke to the picture. Every time he thrust his hips, wet squashes whizzed out from the depths of Belle’s pussy, grating heavily on his ears. Some of them were so noisy and so unbelievably filthy that he couldn’t help but cringe.

There could be little doubt that Applejack’s treacherous dick was twitching after each nasty sound that her jizz produced, joyfully reliving the time it was inside Belle’s cunt. Mac even felt the stench of her cum when he breathed in, or so it now seemed to him. He inhaled once more, and to his horror the offending smell of fresh sperm appeared to grow stronger yet. Belle suddenly raised her eyes, looking up somewhere beyond his face in surprise. That’s when two thick orange legs finally came into his view, completing the picture.

Mac abruptly stopped his thrusts and raised his head. Applejack smiled at him apologetically, though that hardly excused the unexpected interruption, or how close her erect cock now was. The tip was less than a foot away from Belle’s face, still coated in jizz and exuding a powerful, nasty smell that made Mac scrunch his nose.

“Sorry, big brother.” Applejack slowly stroked her dick. “Ah was just thinking maybe ya could help me blow a second load?”

“AJ, have ya lost ya mind?” Big Mac couldn’t believe the gall. His frustrations with her threatened to explode into something very ugly. How could she possibly think asking for this right now was a good idea?

“Please, Mac… Ah really need it. Ah just can’t help it…” She stepped even closer, her drooling cockhead bobbing threateningly near to Belle’s face, the mare’s eyes focused on the wet tip looming over her.

Mac felt anger boiling up within him. The sheer shamelessness of his sister’s actions after all she had already done was tearing apart the remnants of his brotherly affection.

“Stop it!”

Applejack froze in place. The only movement was a mighty jerk of her shaft, a big glob of pre flowing out from her slit and descending to the ground, nearly touching Belle’s mane on its way down. There was a strange, neutral but slightly pleased expression upon Applejack’s face, almost as if she was daring Mac to scorn her even more.

If that’s what she wished for, she was definitely going to get it now.

“Ya’ve pushed yer luck far enough, sis,” the stallion growled, thrusting himself up into a vertical position and looking at her with contempt. “Can’t keep yer cock down? Go kiss mah flank and jerk yerself off then. But don’t dare interrupt us again, or ya gonna make me really mad. Ah’m not giving ya any more warnings. Did ya catch me, Applejack?” He pinned her down with an eagle-eyed stare, waiting for an answer.

AJ retreated, taking her hands away from her cock and locking them behind her back. A nervous gulp traveled down her neck.

“Ah gotcha, Mac.” She bowed her head and walked around the pair. Her shaft bobbed heavily in front of her, still hard and throbbing.

Big Mac followed Applejack with his gaze, lowering himself down and preparing to continue his business with Belle. But to his surprise, AJ didn’t leave them. Instead, she stopped next to his rear and got on her knees, pursing her lips and pressing them squarely into his cutie mark.

Mac was so dumbfounded he forgot his anger. “Whatcha doing, AJ?”

“Ya told me to kiss yer flank, didn’t ya? So that’s what Ah’m gonna do.” She placed another kiss, shifting closer to his asscheek.

“Ah didn’t mea-...” he began, but then stopped himself, unwilling to get into another argument. If that’s what his sister really wanted to do, he wasn’t going to interrupt her. Whatever mischief she might’ve had in mind, if any, she was still the one kissing his ass, so why should he care? After all the things she has done, he definitely didn’t mind the feeling of her lips upon his rear. Really, this was the least she could do to repay her transgressions!

“Hmmph… whatever.”

Mac turned away from her, returning his attention to Belle. As soon as their gazes met, she pulled him into a kiss, her hands running across his muscles, her soft breasts squishing into his chest.

“Hnngh… I’ve never heard you talk like that. It’s so fucking hot,” she whispered, gushing over him, sucking his tongue and swallowing his spit, her eyes full of devotion and lust. “Fuck me as hard as you can, love. Treat me like you own me. Don’t restrain yourself.”

Truth be told, that notion of ownership just made Mac cherish her all the more. He took great care with his things, after all, especially ones as fine and delicate as his dear Belle. But how could he not treat her to the best pounding of her life when she asked him so nicely for it?

The wrath at his sister was still stirring within him, which made rash, aggressive deeds seem unusually appealing. As soon as Belle made her point, his hips seemed to thrust forward of their own accord, plunging his cock deep inside and hitting the mare’s cervix. One exceedingly satisfied moan later his body was repeating the motion, quickly pulling back and then slamming forward even quicker.

Mac let his instincts take control, following the pleasure that spread through his groin before the judgment of his mind. It was easy to do that when Belle’s moans rang in his ears, looking at her ecstatic open-mouthed expression, eyes bulging out in pleasure.

Even beyond the intense satisfaction of repeatedly plunging inside the mare’s tight, hot, dick-milking tunnel, Mac could feel the subtle but distinct touch of AJ’s lips on his ass. The constant movement of his hips made her self-imposed task more complicated, but she didn’t seem to back off one bit. On the contrary, she kissed and licked his big masculine behind with much greater devotion than Mac would’ve ever expected. Her nose rubbed against his flank as he thrust it back and forward, while her tongue soaked his cutie mark in drool. He could feel the moist appendage running up and down along his thigh and buttcheek, leaving a wavy trail of spit on his fur.

In any other situation, it would only be a bizarre distraction at best. But right now it seemed like quite an appropriate addition, stroking his feelings of justified outrage and making his cock twitch and tingle. He actually enjoyed his sister’s humiliation, Mac was forced to admit. But could anyone blame him? He certainly won’t blame himself. It was Applejack’s own fault really. After all the pleasure she partook in at his expense, he won’t try to stifle his own. In fact, he’ll do the opposite, enjoying the moment to the fullest, and his sister’s subservience in particular.

Just to rub it in a little further, Mac wagged his tail from side to side, hitting Applejack across the face. The orange hairs slid across her features, some momentarily sticking to her tongue, while others tickled her nose. He kept at it, his tail striking her each time he pushed his hips forward, but Applejack remained in place, letting it brush across her cheeks while she licked his backside.

The sensations were seemingly insignificant next to the avalanche of throbbing pleasure stemming from his cock, yet it were these little things that amplified his glee to the extreme. They served as a great relief for his pent-up frustrations with his sister. Even if each swing of his tail that smacked her face was only barely perceptible to the stallion, that was still enough to produce a pleasant tingling in his huge, wobbling balls.

Those great red orbs were now hitting Belle’s butt with near maximum force too, their impacts strong enough to produce audible smacks. Mac wasn’t just thrusting anymore – he was jackhammering her pussy with his massive cock, each push resulting in a loud, melodic moan.

“Cum inside me, honey. Fill me up with your foal batter. I know you want to do it.”

Mac felt his control slipping, orgasmic pleasure spreading through his crotch. It was impossible to keep it at bay when Belle herself was asking him to surrender to his feelings. She surely knew that he was close and what kind of effect her words would have on him. He managed to delay his climax only for a little while, slowing down his tempo and instead going for several hard, powerful thrusts, driving the full length of his giant cock into her spasming cunt. That way, he could turn up the speed and ferocity of his movements as high as possible for the final stretch.

And boy did he deliver. In one turning moment, all of the apple-bucking strength of his hips was put to use in destroying Belle's cunny. Rapidly burrowing into her tunnel, battering her cervix like a ram, his massive cock had become a true pussy-wrecking menace that made the mare's brain short-circuit from the intensity of her sensations. She couldn't even scream, instead she let out high-pitched ah's and oh's in rhythm with Mac's thrusts like a pony-sized squeaky toy.

He kept pounding for as long as he could, prolonging their gratification until neither of them could take it anymore. When he hilted inside Belle for the last time, he suddenly noticed that Applejack had switched her lips from his ass to his trembling orbs. As her tongue began massaging the back of his sack, the load that was already rising from within his balls rushed out with unbelievable force.

A deep involuntary groan escaped his mouth when the first of many shots of his thick, hot seed exploded from his cockslit, and through the mind-numbing haze of his release he saw Belle's eyes open wide. After the second and third long voluminous cum-blasts, her fucked-stupid grin turned into an orgasmic ‘O’, her pussy thrashing around Mac’s shaft as his steaming jizz spread throughout her tunnel.

With just the first few shots Mac had already launched almost as much spunk into her cunt as Applejack did during her whole climax, and yet this had been just the beginning. More and more sperm streamed out of his cum-tube, filling every nook and cranny within Belle’s depths. Not even the tiniest of spaces managed to evade that fate – the stallion’s cock and his nut-goo completely dominated the place. And when there was no more room to fill, his cum spurted out of Belle’s pussy, leaking out in big, clingy globs, covering his balls, white gloopy ropes stretching down and breaking off to fall on the ground. The rush of his jizz washed out Applejack’s load, though some of it mixed in with his own, the sperm of the two siblings swimming side-by-side through the thick primordial soup nurtured within their overproductive testes. As Mac’s cock continued spewing cum seemingly without end, the balance of power skewed ever heavier in his favor, his swimmers outnumbering Applejack’s 2-to-1, then 3-to-1, 5-to-1, and on and on it went, a whole army of genetical invaders taking back the land that rightfully belonged to them, squeezing out the opposition and ganging up on their outnumbered soldiers.

All the while, Applejack continued kissing, licking, and suckling her brother’s twitching balls – something he enjoyed way more than he would’ve ever expected to. It was easy to accept any depravity with orgasmic pleasure taking over his body, so when her tongue touched his sack and something deep and primal fired off in his brain, he did not resist it, letting the perverse notions fill his mind.

Sugar Belle hugged and kissed him while he came and her own orgasm wrecked her to the core. The endless flow of his hot jizz had easily brought her over the final edge, forever cementing Mac as one true owner of her pussy. Here she thought Applejack’s load was large, but he had blown her completely out of the water. Where Applejack was big, Mac was bigger: his height, his muscles, his cock, his balls, his everything. Never had Belle been able to internalize that difference as much as she did today. Mac was simply on another level of strength, girth, and virility. And two levels above a regular pony. As a committed lover of all things big, Belle viewed Mac’s humongous size as nothing short of Celestia’s blessing, now more than ever.

For Mac himself, sharing this intimate moment with her was definitely very special, yet his mind was tearing itself apart under the storm of conflicting thoughts and emotions concerning both his wife and his sister. The ecstasy of his release persisted for as long as cum was pumping out of his cockslit, tens of seconds of pure pleasure during which his psyche tried to turn every thought into additional fuel for his lust. It found a surprising amount of success, given the turbulent nature of his feelings. Love and adoration for Belle intermingled with a sense of dominance and justified retribution over Applejack. Each emotion, each memory was accompanied by a powerful throb. A new wave of pleasure passed through him with every subsequent blast, making Mac see his relationships through an elated, deeply sexual perspective, where the twitching of his cock overruled all reason and logic.

By the end of his orgasmic haze, Big Mac felt like a stallion born anew, irreversibly changed by the experience. Everything that happened before seemed like it had been in another life, one where Applejack submissively licking his balls was a ridiculous fantasy and not an inescapable reality. Even after his climax came to an end, she didn't stop nuzzling and suckling his nuts. The tingly sensations underneath his crotch served as a constant backdrop for Mac's post-fuck makeout with his wife, turning an intimate affair between two loving ponies into something much more obscene. He didn't try to stop her, though.

"Oh, dear Celestia," Belle breathed out weakly. "I can… barely… ahh… think straight. This was… incredible." Three orgasms in a row had clearly done quite a number on her.

Not one for many words, Mac simply continued hugging and kissing her, moving his hips just a little to create some pleasant friction between their nethers. They stayed in their respective spots for a short while, Mac and Belle relaxing, while Applejack continued worshiping the stallion's balls, giving some attention to his rear once again as well. Standing on her knees behind him, she could quickly swap from licking the cutie marks on either flank to peppering his big red tush with kisses to washing his sack with her spit. And judging by the regular thumping that reached Mac's ears, she was also furiously jerking off in the process.

"Seems like your sister needs your help," Belle chuckled, noticing the sounds too.

"She can wait," Mac responded, loud enough for Applejack to hear. A moment later, his tail swiped dismissively across her face. That demeaning act didn't slow Applejack one bit; on the contrary, she licked him all the more fervently, continuing to stroke her cock.

"Haha, it's up to you of course, love. But I wouldn't mind it~" A playful smirk ran across Belle's lips.

Mac raised his brow, unsure if she was thinking the same thing he was. Judging by her expression, Belle was definitely expecting a show. She responded to his inquisitive gesture with a wink and a loving smooch on his nose, giggling softly and glancing towards Applejack.

It wasn't Belle's encouragement that made Big Mac move in the end, though her impish words definitely had an effect. The stallion would've loved to keep lying on top of her for a while longer anyway, sweet and comfortable as it was to do so, but another issue soon arose. That issue was his cock. The thing refused to be sated, swelling anew before it even had the chance to fully soften. At the same time, the stallion's rekindled lust was quickly reinvigorating him. Already the second load of salty jizz was churning in his massive nuts. This one was not meant for Belle though, but for the mare he knew and cherished all of his life.

It was a peculiar thing that he desired her most exactly when he was also most displeased with her. Yet maybe he shouldn't be so surprised – these kinds of possessive, selfish feelings had often flared up in the past in the moments of conflict. He always managed to keep them confined to the darkest depths of his mind… or so he thought. Could it be that his sister had noticed something after all?

Big Mac enjoyed one final tongue kiss with Belle and then pushed himself up, a bridge of spit stretching and breaking off between their lips. He pulled his hips back, slowly dragging his cock out of her utterly demolished cunt. Clumps of cum were stuck to his tool while thick gooey strings hung underneath it, swaying lightly. Still, most of his jizz simply flooded down onto the ground or remained inside Belle's pussy.

When Mac's cock was out, she pressed her legs close, leaving space only for a small trickle of cum out of her spunk-packed marehood. Seemingly by instinct, one of her hands reached down to her folds and gave them a rub, her thumb casually flicking her clit.

Meanwhile, Applejack moved to the side, still on her knees as Mac stepped back and turned his attention to her. Their gazes met, two pairs of green eyes assessing each other. Even after tasting his balls, AJ had maintained an air of impudence, barely restraining the corners of her lips from stretching into a smirk. But with his sister looking at him from down below, her daring expression only reinforced Mac's dominance. It was difficult to look tough when his huge, semi-hard cock swayed just a few feet away from her face.

"Have Ah been a good girl, sir?" she asked in a voice that was so sweet, it almost seemed like she was mocking him.

Mac's shaft jerked up anyway, attracting her gaze. Her lips parted slightly at the sight, pupils focused on the swelling tip, before returning back to his face a few seconds later, blazing with lust. Despite the eager reaction of his cock, the stallion kept his composure.

"That was a good start, Ah guess. If ya think it was enough to cross off yer bad deeds, yer gravely mistaken." He pressed her down with his gaze, enjoying the feeling of power and control that his height advantage afforded him.

"Oh dear. Ah sure hope ya won't make me do something nasty and embarrassing!" Applejack cooed.

"That's not up to ya to decide." Big Mac placed his palms on his waist and took a step forward. "Now clean this up." He pointed at his heavy, swaying cock.

Applejack looked at the thing, as if for the first time. She bobbed her head from side to side to get the full view while her eyes roamed across its jizz-streaked surface. Seconds passed as she intently studied Mac's tool, taking in every splotch of cum, every string of gloop dangling from it. One of those strings was slowly stretching down underneath her gaze, its middle thinning under the weight of a big gooey dollop at the bottom. Eventually, it tore apart and fell to the ground, making Applejack glance down momentarily. When she raised her eyes, she wasn't looking at Mac's dick anymore, but at his face.

"Yer so cruel, Mac. Making yer little sister clean this big, nasty cock," she pronounced the last part with emphasis, tasting the words as they left her mouth. "Is this truly what ya want?"

"Eeyup! And ya better start on it soon, 'cause Ah'm losing mah patience."

"If ya say so. Wouldn't want to… mhmm… make mah dear brother wait," Applejack spoke slowly, making a deliberate pause in the middle of her sentence. Mac glared at her with impatience, but the cheeky mare simply shrugged it off, answering him with a teasing smirk as she finally raised her hands up to his cock.

She began by wrapping her palms around the base of his shaft. After getting a nice, firm grip, she slowly slid her fingers along its whole surface, gathering as much jizz as she could. By the end of the stroke, there was an overflowing mass of thick, smelly cum cupped within her hands.

Applejack looked up at her brother, raising her arms. "So whatcha want me to do with this? Should Ah…"

"Spread it over yer cock," he simply stated.

There was a momentary surprise on Applejack's face, quickly replaced with a lewd, understanding smile.

"As ya wish." She carefully brought her cupped hands down to her shaft.

"This ought to repay ya nicely after Ah had to deal with yer sloppy seconds." Mac felt some catharsis watching his jizz start dripping on Applejack's fat orange cock. Now she too will know what it feels like to dip her privates in her sibling's spunk.

"Ohhh, this is certainly a mighty fine reimbursement. Thank ya, big brother!" Applejack practically moaned as his cum began descending from her hands down onto her madly throbbing dick. "Nnngh… it feels so warm." She stroked her shaft with both of her palms, spreading Mac's fresh jizz all over it.

"Ehh… are ya actually enjo-" The stallion stopped himself mid-sentence as he understood the futility of continuing his question. His mouth agape, he stared at his sister, marveling at the vigor with which she coated her cock in the sperm that was swimming inside his nuts not ten minutes ago. She seemed so into it that it almost made him feel embarrassed.

“Ya were saying something, Mac?” Applejack accentuated the sentence by giving her cock a hard pump.

“Yer… yer look pathetic. Ah thought ya were a proud mare, but turns out yer nothing but a weak, submissive bitch,” seeing no other option to recover his authority, the stallion went into an attack, trying to make his words sting as much as possible. With a resentful flick of his cock, he covered her face in a smattering of cum droplets.

“Ya wound me, brother,” Applejack said, offended. “Are ya really calling yer dear little sister a submissive bitch? What would’ve mother said if she heard ya speaking like that?” Her mildly angry expression would be more believable if her tongue didn’t dart out of her mouth to lick up the jizz that landed near her lips.

“Probably the same thing she’d say to ya if she saw ya looking so pleased while covering yer cock with mah seed. Ah reckon she might’ve even agreed with me then,” Mac shot back, still unable to believe Applejack was actually enjoying it.

“Hey, nothing wrong with a bit of family fun,” she just smiled, giving her meat a nice jerk.

“Is that how it is?” He pointed the tip of his dick at her mouth. “And what about blowing yer brother’s cock? Is there anything wrong with that, sister?”

Applejack pretended to contemplate his question for a second, briefly furrowing her brows. “Hmm, Ah don’t think so,” she concluded.

“Come here and suck it then,” Mac said sternly, beckoning her with a shake of his tool.

AJ shifted her gaze to the wobbling shaft and softly nodded, but didn’t hurry to do his bidding. Even with his cock hanging right in front of her face, she took her sweet time with the task, purposefully teasing the stallion. At first, she placed her mouth next to his tip, not quite touching it, just tickling the head of his cock with her hot breath. She stayed there for a painfully long time, breathing in and out, looking up into his eyes. It seemed like she was trying to guess when he'd lose his patience.

As Mac was seriously considering doing something, Applejack finally touched his crowned tip with her lips. The contact didn’t last too long though, and soon she was back to tantalizing him with her breath. Occasionally, her tongue slipped out from her mouth to give his dick a lick, gathering the pre-cum that leaked from his slit. At other times she brushed her plush cock-teasing lips across his tool. But no more than that. Unsurprisingly, it only made Mac more frustrated.

“Will ya stop fooling around and do what Ah said?” The stallion finally grew annoyed and scolded her. To make the point clearer, he raised his cock and smacked Applejack across the face. “If ya don’t, Ah will need to take the matters into mah own hands.”

The threat made her ears perk up, a lewd smile spreading across her lips as gears turned inside her head. There was definitely something naughty on her mind.

“And what will ya do then? Gonna fuck yer sister’s mouth?” she inquired, her voice soft and innocent.

“Maybe Ah will.” Mac looked sternly at her.

With their gazes locked, Applejack placed a light smooch on his tip. “Ah don’t believe mah sweet old brother would ever do something like that.”

As soon as she finished her sentence, a strong red hand landed on top of her golden locks, giving her skull a warning squeeze.

“Don’t test me, AJ.” Mac was getting tired of her games. Not only did she refuse to properly suck his cock, but now she was taunting him too. Messing with a horny and motivated stallion was a perilous endeavor, but had his sister ever let that stop her?

“Come on, Mac. We both know ya won’t…”

Her utterance was brought to a sudden end by a thrust of Mac’s hips, his thick cock plugging her disrespectful mouth. The stallion sighed as her grating voice was replaced by the sound of smacking lips, and wet heat enveloped the tip of his shaft. The enormous size of his tool ensured that no offending words could leave her lips.

Mac’s fingers dug into Applejack’s hair as he pulled her in, forcing his dick deeper into her mouth. She didn't resist, her stretched-wide lips gliding seamlessly along his hot, throbbing length. He pressed on until his cockhead reached her throat, with the mare showing first signs of unease. Her expression grew more focused, but a teasing spark still remained in her big green eyes. It was as if she was asking him to shove his dick deeper, daring him to choke her with it and truly punish her like the bad girl that she's been.

It was incredibly enticing to do just that, to push his cock as far as he could and let the warmth of her mouth wash over his flesh. The fact that it would make AJ suffer seemed only like a bonus now. And yet he still couldn’t quite bring himself to violate his sister so brutally. A little note of mercy had remained within his heart – the only thing that kept his beastly instincts from taking charge. Applejack simply didn’t know what awaited her if she pursued this foolish route. He saw just how massive his cock was next to her muzzle, how much it had already stretched her jaw. If he were to truly fuck her face, that would absolutely ruin her. There would be nothing left but a pathetic, slobbering mess. Surely, once he gave her a feel for the future that awaited her, she would understand this and reconsider!

Barely a quarter of his shaft was inside, and her mouth was already full. He bobbed AJ's head on his cock, pushing it lightly into her throat to give her a taste of what she could expect if she refused to properly submit to him.

Mac had to admit, he liked his sister much better when her lips were wrapped tightly around his dick. The intoxicating feeling of control over her made his shaft twitch with unusual regularity, again and again sending big globs of his syrupy pre down her gullet. He enjoyed looking at her beautiful face, staring into her eyes while she washed his shaft with her spit.

The longer he kept Applejack speared with his cock, the more signs of strain and discomfort appeared upon her face, her brows twitching, nose scrunching, sloppy gurgles rocking her throat. This steady disintegration of her resistance was exactly what Mac wanted to see. If he wanted to make her experience more miserable all he had to do was to shove his cock a bit further, which also had a nice side effect of stimulating his shaft. All in all, this was definitely the most gratifying way to discipline his sister.

Yet despite her obvious struggles, Applejack still tried to challenge him with her gaze, maintaining that cocky look he was so familiar with. She was nothing if not persistent in her arrogance, even if the copious amount of dickspit dribbling from her mouth made it difficult for Big Mac to take her defiance seriously. He was sure that her resistance was severely weakened after he had given her throat a well-earned scratch with his swollen crown. She would definitely think twice before disobeying him now.

"That enough meat for yer plate, AJ? Or do ya still think yer brother won't have the will to fuck yer pretty face?" He chuckled, pulling his cock out of her mouth.

As soon as the dick-seal on her lips was broken, Applejack coughed out several wads of nasty spit-webbing, aiming it directly at the masculine tool that was at fault for her involuntary outburst. Her drool hung from the shaft in gross, translucent strings, serving as a poignant reminder of the threat it posed to her mouth. Applejack proceeded to gather even more saliva on her tongue and then spit it out on Mac's cock too in an apparent act of defiance.

"Enough ya say? Honestly, Ah barely even felt it. All ya did was prove me right." Applejack playfully pushed her tongue out, sneering at the stallion, but to Mac's horny gaze this teasing gesture served as little more than a welcome mat for his cock. He rubbed the head of his dick across it, leaving behind a trail of translucent pre-ejaculate goo for her to swallow.

Mac had to admit, his sister's willingness to be so daring even when her coughed-out drool was still swaying underneath his meat was almost commendable. Applejack always stayed true to herself. She wasn't one to put on a mask just to please someone else. In any other situation this would be worthy of Mac's highest respect… But not after she came inside his wife's unprotected pussy, quite possibly impregnating the love of his life right in front of him!

"Open yer mouth," the stallion barked a simple command, having no desire to answer Applejack's quips. Eyes narrowed, his fingers pressed forcefully into her skull. He was tired of playing games.

In response, Applejack's tongue, profusely covered in his cock-slime, slid back between her lips. She rolled the tangy liquid inside her mouth with demonstrative slowness, as if tasting a refined dish. But the sight of his sister relishing in the flavor of his precum wasn't enough to placate Mac now – his fingers clenched harder with every second she delayed fulfilling his command, pulling on her hair to the point of pain.

And still, Applejack performed her intentionally prolonged show despite the painful tugging of her mane, ending it with a big gulp that sent Mac's precum into her belly. It seemed that she wanted to show off her empty mouth to him as well, but that was not to be – as soon as her lips began to split, Mac roughly shoved his cock inside, forcing her jaws wide open much quicker than she intended to.

With a steady push of his hips, the stallion's thick red meat advanced through her mouth once again, faster and more insistently than before. He held her head with both of his hands and pulled it towards his crotch, treating his little sister like a cheap cock-gobbling slut. Applejack's cushy lips wrapped tightly around his shaft as it slid inside, her tongue pushed to the bottom by the throbbing behemoth. Deeper and deeper it went, entering her gullet and persistently moving forward. His fat cock was gradually enveloped by the humid warmth – a welcoming sensation that was practically sucking him in. This time Mac did not resist its pull, letting his hips follow their natural trajectory, driving his dick into the moist hole that welcomed him so kindly.

His grin widened as he watched his sister grow tense, her hands rubbing his calves while her brows twitched and her eyes bulged. He felt slight resistance to his movement, slowing down his advance, but only by a little. After all the difficulties he had penetrating Belle's pussy, it was surprising just how easy it was to lodge his tool deep into his sister's mouth. It had been as if her throat was made to suit his cock. With the passage being as smooth as it was, Mac didn't plan to stop until he got most of his shaft inside her maw. As his fingers locked firmly behind her head, it would be just a matter of time until his medial ring came knocking at her lips.

That thick fleshy bump was getting awfully close now. As Mac's drooling cockhead snaked down Applejack's throat, a visible bulge had formed on her neck, growing bigger and more obscene with each second. Her breath slowed and then stopped almost completely when her windpipe was obstructed by her brother's way-too-fat dick. Unable to secure the most basic sustenance required to maintain life, she was now wholly dependent on his pity, of which Mac had a notable shortage.

He did pull his hips back, letting some musky air enter her lugs, but only to slam his cock forward with an even greater force a couple of seconds later. After that Mac continued feeding his meat into her mouth until she reached his medial ring, which marked just a little more than half of the way down his shaft. It was so damn enticing to stretch her lips even more by pushing it in, but Mac stopped just short of doing that, feeling Applejack's grip stiffen as she gagged hard on his dick.

And then he remembered her unashamed cry of pleasure when she came inside Belle. A sadistic urge told him to pull Applejack closer, and he surrendered to it, forcing her lips to accommodate the thickest part of his cock. Mac was pleased like never before to see struggle and discomfort upon his sister's face, the pain in her shaky, almost pleading gaze. She coughed hoarsely, huge nasty wads of drool sputtering from her mouth around his shaft, while tears welled up in her eyes. With every passing second her expression grew more miserable, but she did not try to pull back, looking up at him with as much conviction as she could muster.

Which wasn't a lot. Choking on Mac's massive cock definitely did quite a number on the proud and dignified mare. Satisfied with the initial results, he began dragging his dick out of her maw, unclogging her throat and letting life return into her body. Applejack inhaled greedily, sucking in his cock-stench and air in equal measure through her nostrils. Tears trailed down her cheeks, some of them reaching her mouth and giving Mac's cock a salty aftertaste.

He stopped just shy of pulling his tip out. After giving her several seconds to recover, the stallion shoved his spit-dripping tool down her throat once again, tugging on her head and thrusting his hips forward at the same time to achieve maximum velocity. While his speed was greater now, the depth of his plunge had decreased, turning a prolonged chokeout into a fast-paced throatfuck as he quickly repeated the violent motion.

As he did so, Mac's medial ring served as a natural limiter for the extent of his cock's submersion. Most of his thrusts ended up with Applejack's mouth stopping just shy of it, her lips only occasionally reaching the circular bump in a lewd face-to-dick kiss.

"Can ya feel this, AJ?" He growled, dragging her head back and forth along his shaft.

Gagging and drooling were the only responses she could give, which was just fine with Mac. He didn't want to hear her voice when the sloppy gurgles coming from her throat sounded so much better. This was the kind of answer a submissive bitch was supposed to give. And that's who she'll be after he's done with her. No more half-measures.

Whenever his sister tried to contest him with her gaze, he simply pushed his cock deeper into her spasming throat, inevitably breaking her resistance. Every attempt to look tough was met with swift reprisal, as his hips only yearned for an excuse to drive his dick further inside of her maw, gladly taking every opportunity to choke out the remnants of Applejack's unruly spirit.

After several minutes of ruthless facefucking the once-proud mare was a proper mess. Her eyes were swimming with tears, turning her brother's silhouette into one big red smudge that grew bigger and smaller in rhythm with the involuntary movements of her head. Face smeared with spit, cock-drool hanging from her chin, she was reduced to being little more than a tight, warm fuckhole for her older brother.

Assured that Applejack had finally learned her lesson, Mac dragged his cock out of her mouth. Numerous strings of spit, thick and thin, stretched out between his shaft and her lips, breaking off one by one as he pulled away.

With her airways unblocked, Applejack breathed in greedily, only to cough out all the air as soon as she inhaled it. Her next attempt was more successful, letting the mare recover some of her senses. Even after facing such a rough deepthroat by the biggest cock in town, her state was actually improving with surprising speed. As her breath steadied, she licked up the saliva from around her mouth and even bent forward to suck in a few blobs of gloopy liquid that drooped under Mac's shaft. Applejack's endurance was proving to be legendary for a good reason.

But however swift her recovery was, no amount of fortitude could wholly undo the visible degrading effects of being forced to swallow a huge, pulsing, leaking fucklog. A disheveled mane, stray hairs stuck to cheeks and forehead, eyes red from crying – these were only a few of the notable features Applejack had acquired under her brother's rough treatment.

Seeing her in such a state, it was difficult for Big Mac to imagine his sister continuing to put up a facade of a stalwart, unyielding mare. Yet Applejack managed to outdo his imagination, boldly staring up at him with a shaken, but still unbroken resolve just half a minute after he thought he had left her utterly defeated. Her muzzle was wet with tears and spit, her throat sore after enduring the friction from his girth and its own involuntary contractions, but she barely seemed to notice it, looking as determined as she possibly could.

All of it only served to make Mac angrier. Why did his sister have to continue goading him, forcing him to abuse her in ways no brother ever should? He was showing her with his every action and word that he was ready to go all the way if need be, but that still didn't dissuade her, quite the opposite.

Applejack casually brushed several unruly strands of hair from her face, hooking them behind her ear. "Is that all ya can do, brother? Ah guess planting mah seed inside Belle's womb was no big deal after all…"

For a split second, Mac's expression froze in astonishment while his brain processed what he'd heard, refusing to believe it. The words rang loud in his ears, resounding within his head as clearly as if Applejack had repeated them again and again.

"No big deal…"

How dare she even think something like that! Every fiber of his being exploded with indignation. His eyes shone with righteous fury, hands clenching into fists, muscles bulging, violent impulses threatening to break out of his control. But no words left his tightened lips. And when his mouth finally opened, it was only to send a big ball of spit directly into his sister's smug face, hitting her squarely on her muzzle.

The disrespectful gesture didn't seem to perturb her at all. On the contrary, a dumb grin spread across her face, while a long, glistening string of Mac's saliva stretched under her nose.

His mind bubbling with malicious intent, the stallion circled around the kneeling mare, grabbing her by the roots of her hair and yanking her head back. He stood behind her, forcing her head into a horizontal position, her torso leaning back to accommodate it.

"Open your fucking mouth." The stallion delivered a stinging slap to her cheek in time with the command. It was a light hit by Mac's measure, but painful enough to make her obey instantly. Quickly bending down towards her, he spat once again, now directly between her lips.

"This is yer fault, sis. Ya made me do it."

Applejack shivered underneath him, swallowing his warm, bitter drool. If Mac looked down at her crotch, he could've seen her cock jerking up with perverse pleasure. But he was too focused on directing his own tool into her mouth, descending upon her face from above with his massive frame.

His swollen shaft hung a mere inch above Applejack's muzzle, placing it right in the middle of her view, the rest of his body barely visible beyond its girth. It slowly slid forward as Mac took a comfortable stance on top of her. With one of his hands on the back of Applejack's head and the other below her neck, the stallion lined her up to create a straight tunnel from her mouth into her throat, making it that much easier for his cock to plow right through her.

And plow it did, driven by a hard push of Mac's hips. He forced half of his dick into her mouth and continued on, feeding her more and more of it, quickly passing the medial ring. Soon only a third of his cock remained outside, and even that much didn't stay unsucked for long. With one final lunge, he shoved the rest of his shaft between her lips, his hefty balls smacking Applejack in the face.

In this position, his musky cum-pouch was the only thing his sister could see. No longer could they lock gazes while his cock was deep inside her mouth. So much the better, Mac concluded. She didn't deserve to look at his face after what she'd said anyway – his balls would be a much better target for her disrespectful stare. Applejack could adopt whatever daring expression she desired and his swinging testicles won't mind one bit. It definitely won't change the fact that they were striking her muzzle each time Big Mac thrust his hips.

Those thrusts started coming one after another with brutal savagery, the stallion moving like he was fucking the stretched-out pussy of his wife. In fact, he had cared more about Belle's cunt than he did about his sister's throat at the moment. This was a punishment after all, so all the pain and discomfort were simply a necessary part of the learning process.

Rapid pounding was interspersed with deep, prolonged submersion of his dick. Nearly every second of her predicament was a depraved exercise seemingly meant to train her to be his personal cock-swallowing fuckdoll, providing great pleasure to the fuming stallion, while she was forced to endure the perverse distention of her throat.

He let her rest only long enough to keep her conscious, periodically sliding most of his shaft out of her mouth and giving her a few seconds to get some air. But even then, he would pull her head up, pressing and rubbing her nose into the bottom of his cock while she breathed. And after hilting inside of her anew, he would grind her muzzle in the cleft between his fat nuts, making sure that whatever measly amount of air she could inhale there would be filled to the brim with the stench of his sweaty sack.

Minute after minute, Mac kept hammering his sister's face, while she was forced to bend over backwards for his convenience. As time went by, her brain began slowly shutting down, the diminished oxygen intake barely enough to keep her on the edge of consciousness. Her body slackened as strength began leaving her. Soon, it appeared as if the only thing keeping her upright was her brother's grip.

Mac pulled his cock fully out of her mouth only once, and it was for this very reason. Looking at Applejack's face from above, he impatiently slapped her cheeks a few times to make her open her half-lidded eyes. As his ballsack quaked with an impending climax, Mac knew he wanted her to be in full awareness for what was about to come. He was generous enough to let her take several deep breaths while spit dripped from his dick onto her utterly ruined face.

Her current state was so terrible it made everything before that seem like child's play. The repeated smashing of his huge heavy orbs into her face left it not just moist, but completely covered in a foul mix of sweat and spit. Thick strings of it had stretched out between her skin and his sack every time he pulled his hips back, and by the end the smacks had acquired a distinctly wet sound. All of that nasty, sticky liquid had been constantly descending down into her hair, turning her tidy, beautiful mane into a convincing imitation of a used dickrag. Her locks were stuck in wet clumps and covered by a filthy webbing of dick-infused spittle, their state not made any better by Mac's rough grip and his constant manhandling of her head.

And he wasn't done with her yet! After he'd verified that Applejack had returned back to her senses, Mac unceremoniously shoved his cock into her mouth once again and continued ferociously rutting her throat. His anger and the burning desire to discipline his sister had energized his movements just as much as his out-of-control libido did, which meant bad news for Applejack's esophagus. Mac was giving it his all during this last stretch, preparing to dump his hot spunk into the mare's thoroughly hatefucked mouth-hole.

When he sensed his seed traveling down his cum-tube, the stallion pushed the full length of his dick into her mouth one final time, his balls twitching atop her muzzle as a torrent of incestuous jizz spewed directly into her stomach. He felt strangely elated knowing that he was feeding all that filthy goo his giant testicles had produced to his little sister. Watching the expanding swell on her belly, he marveled as it grew bigger after each throb of his cock.

But there also were better uses for his spunk than simply giving Applejack an out-of-schedule dinner. With his shaft still pulsing, he pulled his hips back, dragging it out of her maw until only the tip remained inside. In just a couple of spurts her mouth was completely full, the sour flavor of Mac's cum drowning every one of her taste buds. Subsequent bursts directed the stream of semen in both available directions: further into her throat, and out of her overfilled mouth. With her gullet quickly getting clogged, a portion of his jizz traveled through her open airways, reaching her nose and spurting obscenely out of her nostrils. Only after that did Mac drag his cock out from between her lips.

Cum continued jetting out from his dickslit, a seemingly unending amount of it coming from his monstrously productive nuts. He never felt this good, never had this much jizz blasting out in one orgasm. Mac was ashamed to recognize that a rage-fueled throatfuck with his sister turned out to be even more fulfilling than his first time fucking Belle's pussy. What a terrible pervert he must've been!

And just like any pervert would, he directed the stream of his cum onto Applejack's body. Without his support his sister fell on her back, lying on the ground underneath him, which made her a perfect target for the many ropes of white creamy jizz that regularly burst out from his dickslit. A few of them hit her face, burying her features under a layer of spunk. Others flew towards her body, painting her chest and belly with thick streaks.

At the same time, Mac saw his sister's hands grabbing onto her own throbbing cock and jerking it madly with the last bits of her strength. The stallion pointed his dick at her crotch, sending several cum-strings splashing across Applejack's shaft, greatly reinforcing the clumps of old jizz that were already covering it. This new infusion of fresh, steaming seed was immediately noticed by the mare as the hot goo spread along her cockflesh. Her strokes grew even faster, palms gliding seamlessly across her lubed-up tool. She moaned without shame, and the heavy mass of jizz that covered her face began spilling into her open mouth like a great circular waterfall.

While Mac's release finally started winding down, Applejack had just reached her own. Only a few seconds of pumping her dick were enough to bring it about, showing how close she'd been simply from deepthroating her brother's gigantic bitch-breaker. He observed in amazement as Applejack's cock jumped in her hands, shooting out great wads of cum on the floor in front of her.

Big Mac wasn't wholly sure how he felt about it. On one hand, she wasn't supposed to be enjoying this so much – it contradicted the very point of the rough treatment he'd given her. But on the other, it was just too darn good to watch his sister cumming her brains out after he had used her throat like his personal cocksleeve and covered her head-to-toe in his spunk. Applejack was at the high of ecstasy after he had degraded and abused her, and that gave Mac a sense of power and control that he'd never had over her before.

Every jet of sperm that left her cock was an unarguable proof of her desire for submission to her big brother. Judging by the sight of her, Mac wasn't the only one who had found the biggest climax of his life here. Her whole body positively trembled as she wallowed in her own humiliation, cum shooting out with tremendous force from her dick. Some ropes covered the distance of nearly ten feet, cutting through the air like rounds discharged from a goo-blasting cannon.

The volume of her release was absolutely enormous compared to any regular stallion, but it still paled in comparison to Mac's. Its length was also shorter, tapering off into a drizzle at about the same time that the last batches of jizz leaked out of her brother's dick despite her late start.

As Applejack entered the post-orgasmic blissfulness, a long line of spunk still hung directly underneath Mac's cockhead, slowly depositing upon her face. He could hardly even recognize his sister underneath all the cum after she had taken the full brunt of his orgasm. She was more white than orange now, her coat drenched through and through with his sperm.

"Sweet Celestia…" A soft voice came from behind the stallion.

Mac turned his head and saw Belle staring at his sister with a mix of envy and lust, her fingers stroking her engorged clit. She definitely wasn't beset by boredom while the two siblings were settling their disagreements.

"Can I help her clean up, love?" Belle looked earnestly at the stallion. She wasn't just asking this for Applejack's sake, that much was obvious.

As soon as Mac responded with a nod, Belle was up on her feet, quickly approaching the mare on the ground. Her hand remained on her cunt while she sat down nearby and leaned towards Applejack's head. Hungrily leaking her lips, Belle seemed to be preparing for a feast.

She carefully swept the oozing liquid from one of Applejack's eyes with her index finger and then sent it into her mouth for a taste, sucking the cum off. Belle had to clean the mare's brow and the side of her nose too, or else Mac's all-enveloping jizz threatened to spill over and undo her work. After several more flicks, Applejack could finally open both of her eyes. They were like two floating plates among the sea of white sludge, her green pupils remaining unfocused for a few seconds, until they were suddenly directed at Belle's face.

"Mighty thank ya, sis." Cum-strings stretched out between Applejack's lips as she spoke hoarsely. Even underneath a layer of spunk her smile was unmistakable.

She recovered from her momentary slumber, pressing her hands into the ground and raising herself up. Her arms trembled at first, but she quickly steadied them and then set herself upright with a confident push. All of the gooey stuff that covered Applejack's face and chest now began sliding down into her lap and gathering in a big nasty lake at her crotch. Paying no attention to it, the mare rubbed her tender throat, gulping uneasily.

"Sorry for teasing ya, Mac," she groaned. "Ya did quite a number on me there. Ah think mah throat is gonna be sore for a week."

The stallion took a step forward behind her, casually laying his cock on top of her head, its leaking tip poised above her muzzle. A string of dick-slime descended right in front of her face as he addressed her.

"Will ya be a good little filly from now on?"

"Ah sure will." Applejack leaned her head back, catching the string with her mouth. "And if Ah happen to slip up, ya know what to do. Don't ya?" She placed a loving smooch on the bottom of his cock. "Mah dear brother."

At that moment, Belle lost control and lurched forward, licking up a big glob of jizz from Applejack's chin and smashing their lips together. Her tongue lapped feverishly at anything it could reach, picking up cum from Applejack's face and sliding into the mare's mouth. Mac's spunk swapped from one hungry maw to another as AJ responded in kind.

The stallion watched the two mares he loved more than anything in the world make out in front of him, his jizz dripping from their lips. Belle's fingers were still desperately rubbing her pussy. She trembled, pressing her knees together, almost falling over onto Applejack, but the farm mare kept both of them steady, letting Belle recline on her as they kissed.

Suddenly, Belle raised her gaze up, looking at Mac's cock, and then at his face. "Let me taste it," she didn't just ask, but demanded it.

Mac dared not delay when his mare was so thirsty. Her words were like a trigger for his brain, making him push his softening dick between Belle's and Applejack's lips without a second thought. He did not regret the decision.

A pair of tongues danced across his sensitive flesh, picking up the salty cream that covered it. Slurp, slurp, slurp, Belle sucked in the cum from his tip. She moaned in ecstasy as electrifying shocks passed through her body, wrapping her mouth around Mac's cock when a powerful orgasm wracked her senses.

Applejack licked Belle's cheek and the corner of her stretched lips, targeting the place where her and Mac's flesh met. The stallion simply stayed in place, letting the mares have their fill. Both of them directed their gazes at him, looking submissively into his eyes.

When her climax came to an end, Belle slumped down weakly, pulling herself off Mac's dick. She gave Applejack a light kiss on the lips and rolled over on her back, lying down with a blissful smile and closing her eyes. After going through another powerful orgasm following the first three, she was completely out of energy, and it showed.

Mac shared a meaningful glance with his sister, Applejack smirking as she got up onto her wobbly legs. The throat-fucked mare couldn't stand steady at first, but her strength was recovering with each second.

"Seems like Belle enjoyed the show," she snickered.

Mac stayed silent as he looked at his wife. He could hear his heart beating, blood pumping through his veins. But she seemed strangely serene now – a calming sight after all that happened today. Her big, round breasts heaved softly in rhythm with her breath.

It was more difficult than he expected to tear his gaze away from her chest. After a minute had passed, he'd finally managed to do it, looking around as if he'd forgotten where he was. His eyes stopped eventually on the packed cart in the middle of the barn.

"We need to finish the work, AJ. Those apples aren't gonna gather themself."

She followed his gaze, and then turned back to face him.

"The work can wait. We'll handle it eventually. Ya know how quick Ah can be when Ah need to." Applejack stretched out her body, raising her arms high above her head. "But we all definitely need to clean up, especially me. Ah didn't know you've had that much spunk stored away in those big red balls of yours, brother," she said with a laugh, drilling her gaze into his crotch so intensely it almost made Mac uncomfortable.

After a brief pause, during which Applejack revitalized her sore joints and muscles with a light shake and a few more stretches, she continued.

"Hope ya aren't still mad at me. Ah was just joking around. Ah didn't really mean it when Ah said that, honest."

Big Mac nodded. "Ah know it, AJ. Don't worry." It was easy to see the obviousness of it now that he wasn't so mad with lust.

"Yer the best, Mac! Love ya." Applejack relaxed visibly. "Gonna go grab the hose now. Will ya give me a little smack to send me on mah way?"

"Uhh… wha-?"

The mare turned around with a quick jump, pointing her firm rump in his direction and sending it into a playful wobble.

"Come on, brother, give my ass a lil' smack. Ya slapped one of my cheeks already," – she pointed at the side of her ruined, cum-slick face, "Ah know ya wanna slap these ones as well." Applejack swatted her orange butt lightly for demonstration.

Not waiting for his response, she began hopping backwards in his direction, getting closer until her rear was within a hitting distance.

"Pretty please?"

Mac sighed.

*SMACK*

The powerful hit almost made Applejack's weakened legs lose their balance, while a reflexive yelp escaped her lips. She didn't seem to mind it though, smiling at him like an overjoyed school-filly.

"Now go, ya little tease, or Ah'll spank ya again," he grumbled.

"Yes, sir!" Applejack blew him a kiss and gave her thick butt a cute little shake, before hurrying towards the barn's exit.

As she slipped out of the doors, Mac remained alone with Belle, and his attention soon focused on her. He walked up to his mare and sat down quietly. Mesmerized once again by her massive breasts, he let himself grab one of them. The soft, pliable mass felt calming when smooshed within his palm, helping him relax. As he squeezed it, Belle's lips stretched into a haughty smirk.

"Give me a kiss, honey," she purred, fluttering her eyelashes at him.

Big Mac leaned towards her face, but before he could cover the final inches, she rose up to meet him, mashing her lips into his.

"I think I'm gonna be pregnant," Belle whispered softly, pulling away after a little while of slow and loving tongue action.

"Ah wouldn't be surprised." Mac thought back to the huge mass of jizz that both him and his sister had pumped into her womb. If there was anything to fertilize there, it had definitely been fertilized ten times over.

"You are not upset because of… you know?" She rolled her eyes in the direction of the barn's exit.

"It's fine," Mac answered before he himself knew for sure what he thought. It was quite possible that Belle would bear his sister's foal, and none of them would be the wiser whose child it really was. But did that really make any difference in the end?

"It doesn't matter," he concluded, groping Belle's tit and placing another kiss on her lips.

Epilogue

The door to the house suddenly blew open as a little filly dashed out at full speed. She whizzed past Sugar Belle, nearly tripping the mare up.

"Take care, Apple Bloom, ya almost hit Belle!" Applejack shouted from behind her. "She should get all the space she needs right now, ya know."

"Ah'm sorry! Ah didn't see 'em coming," Apple Bloom shouted back, turning her head only for long enough to wave at the mare and the red stallion that accompanied her. "Ah'm already late as it is, so..." She swiftly ran out into the street, her sentence left unfinished.

"It's fine, dear, don't worry!" Belle chuckled, following the energetic filly with her gaze.

"Howdy, family!" Applejack grabbed their attention. "Come inside, the dinner is hot and waitin' for y'all."

Big Mac nodded to his sister and graciously helped Belle up the porch. She covered the stairs with slow steps, placing one of her hands on her big round belly. It wobbled lightly under her spacious dress as she ascended and made her way into the house. Her husband followed right behind.

"It's great to see ya, Belle." Applejack hugged the mare, careful not to squeeze her too tight. Taking a small step back, she placed a hand on Belle's pregnant belly and gave it an appreciative squeeze. "How's our little apple doing? Been kicking some more?"

"A lot more," Belle laughed. "It should be a month away still, but sometimes I feel like it might pop out at any moment."

"Gonna be a strong one. Like the father." Applejack glanced at her brother with a smile.

The three of them went into the kitchen, Mac and Belle taking their places at the table beside each other, while Applejack poured each of them a bowl of hot soup. With the moment of their foal's birth getting ever closer, the conversation centered, as it often did lately, on all the ways in which the family was preparing for the coming of its newest member. Applejack once again reinstated her commitment to do everything that was possible on her part.

"Harvest season is coming soon, so it's gonna be a busy few months. If ya need any time off, Ah can handle yer part too, brother."

"We'll see. But Ah don't plan to be slacking off," he responded.

"It's not the kinda thing ya can make plans for. Just know that Ah'm always ready to pick up the work if Belle needs ya."

Mac nodded, while his wife beamed Applejack a wide smile.

After they were done with the dinner, the stallion helped Belle raise herself from her chair, while AJ quickly placed their empty bowls into the sink. She circled around the table, coming up behind the pair.

"Ah'm gonna be at Twilight's for a few hours. But lemme take a good look at that pretty belly of yours before Ah go." Applejack began raising Belle's dress before she even finished her request.

The pregnant mare just giggled softly as both her round tummy and her pink panties underneath it were unceremoniously exposed. Getting down on her knees, Applejack pressed her lips into the belly button, tenderly massaging the bulging flesh with her hands.

"Can't wait to finally hold our little baby foal," she whispered, rubbing her muzzle across Belle's skin.

Before standing back up, Applejack casually tugged on the mare's underwear. She raised it just a little bit and then let go, making the stretched fabric hit Belle's waist with a pleasant smack.

"Stay safe."

Up on her feet, AJ leaned toward Belle and planted a farewell kiss on her lips, one that was more than simply friendly. Mac could swear he even saw their tongues darting out to meet each other, swapping little bits of spittle. His cock jerked within his pants as watched it, imagining sinking his shaft deep inside her throat. Applejack was clearly asking for it with her brazenness – something that had become quite usual by this point. He didn’t mind it though, it just gave him another opportunity to discipline her afterwards.

"See ya later, sis." The stallion said, rubbing his crotch.

Applejack's gaze darted down for just a moment. Raising her eyes, she smirked at him and licked her lips. "See ya later, big brother." Her fingers trailed lightly across her chin and neck.

And with that, Applejack turned around and strolled towards the exit, giving her big cowgirl booty a little teasing shake before she stepped out of the doors.
