#1 of Big and Bigger

Big Mac has a problem. His cock is just too big. Too big to properly fit into his pants. Too big to fuck his wife. Luckily, Applejack is there to give her brother a helping hand when he needs it most. But what if she ends up taking it too far?


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.
