Cheese Sandwich had spent many happy times in Sweet Apple Acres’ new and modern barn, hosting birthday parties, the occasional hoedown — and of course the big barn raising party, held on the very day the barn was constructed. But now Big Mac was showing him a feature of the new barn that Cheese hadn’t known existed:

The sex swing.

His hands tied behind his back, suspended helplessly in midair at the level of Big Mac’s muscular hips, Cheese Sandwich gently swayed back and forth, guided by the firm grip of Ponyville’s strongest stallion. Cheese’s low whimpers and groans echoed throughout the barn, and his legs twitched and trembled from their resting places atop Big Mac’s shoulders, as the red stud towered above him and pushed inch after inch of girthy horsecock up the party planner’s virgin asshole.

Cheese was all for adventures and friendship, but this adventure was a little too intense! Big Mac’s cock felt like it was the size of an average pony’s arm, and with every deepening thrust of that massive dong, Cheese felt his sexuality — not to mention his anus — stretching towards a point of no return.

The contrast between Cheese’s own endowment and the big red monster sliding between his buns couldn’t have been greater. Even when sporting the biggest erection of his life (as he was currently), the tippy-tip of Cheese’s cock could barely nudge the 4th inch mark on a ruler. His slender orange stalk of flesh seemed to disappear in Big Mac’s powerful hand as the bigger stallion (in every sense!) gripped it and stroked him in time with his noisy thrusts. Ironically, the earthy, squishy sound of Mac fucking Cheese sounded much like the stirring of a pot full of cheesy macaroni.

“How does it feel, finally gettin’ ta enjoy a real cock?” Mac smirked down at his bound and buttfucked playmate.

“It, erm... it feels a lot better than I thought...” Cheese admitted. “B-but, please, slow down — unnnngh!” he whined as Big Mac’s medial ring popped past his inexperienced ringpiece, stretching the once tight pucker to the very limit.

With a loud ~SMACK~ Big Mac slapped Cheese’s thicc orange bubblebutt, the only part of the party planner’s body that wasn’t scrawny and undersized. “I had mah eye on ya fer a while, ya lil’ sissy,” the mighty stallion growled. He gripped the straps of the sex swing and sawed his dick in and out of Cheese’s thoroughly punished tailhole. “Movin’ in ta Ponyville, flauntin’ yer girly plot all over town. Thinkin’ yer tiny dingaling could ever satisfy a mare like Pinkie.”

“I-I’m doing this for Pinkie!” Cheese Sandwich protested, even as thick spurts of precum drooled from his “dingaling” onto Mac’s stroking fingers. His curly shoulder length hair bounced vivaciously as he struggled, adding to his feminine appeal. “She said she was willing to try anal, b-but only if I went first.” The blushing party pony looked over at his eagerly grinning marefriend, who was sitting in a nearby chair and watching the action alongside Big Mac’s bored looking wife. “Pinkie, you’re into this, right?”

“Yeah, it’s super hawt, babe!” Pinkie Pie cheered, bouncing seismically up and down in her chair. “I really liked the part where you nutted all over your chest! Could you do that again, pleeease?”

“Pinkie, we’ve talked about this, I can’t just cum whenever you — unnngh!” Even as he protested, Cheese Sandwich found himself pushed over the edge as Big Mac finally hilted himself fully, his mighty nuts slapping against the smaller stallion’s butt. The two guys’ hips met with a solid thwack, giving the “all clear” to Cheese Sandwich’s nuts to tense up and pump out a second load.

It was only 5 minutes earlier that Cheese had first blasted rope all over his fur, at the moment Big Mac’s mighty flare first nudged his tender bitchbutton. Cheese was a quick learner, and was now fully trained as an obedient little bottom, ready to quiver and spurt whenever his prostate was dominated by big fat daddy-dick. His sperm gushed out over his tormented balls, dripping over his thighs and falling like a gentle rain to the floor of the barn below the sex swing.

Cheese gasped for breath as the powerful, pounding sensations in his butt refused to let up. “Please, Big Mac,” he begged, “just give me a chance to catch my breath! It feels too good!” Yet the powerful red stallion just kept fucking the ass before him with long, slow, powerful strokes, undeterred by any thought of mercy or gentleness — of anything except his own selfish satisfaction.

“After I’m done with yew,” Big Mac whispered cruelly to the whimpering little twink beneath him, “I’m gonna take yer mare. I’ll show Pinkie what a real stallion can do, an’ once I do, she’ll never be satisfied with this tiny clit yew got between yer legs.”

“N-no!” Cheese Sandwich sobbed, struggling in his bonds. “I love Pinkie, p-please don’t take her from me!” But his twice spent dicklet was already stiffening again, belying his denials. “Erm, and especially don’t make me eat your creampies out of her pussy, I’d hate that!”

“What a hottie my coltfriend is!” Pinkie squealed from the sidelines. “Don’t you think so, Sugar Belle?” She leapt out of her chair with excitement and flung her arms around her Sugarcube Corner co-worker. Pinkie’s oversized earth pony tits flopped about wildly in her T-shirt, brushing with nipple stiffening force against the unicorn’s perkier pair. For Pinkie Pie, bras (not to mention panties!) were an entirely foreign concept. “I think our guys look sooo handsome when they’re having sex together!”

Sugar Belle raised an eyebrow at her friend’s enthusiasm, even as her grunting husband drove his entire length up Cheese Sandwich’s butt with long, forceful strokes. She leaned into Pinkie’s energetic hug and whispered confidentially: “Did I just hear that you’ve never done anal with Cheese?”

“Huh?” Pinkie scratched her head. “Of course we do anal! He drove up my dirt road just this morning!” The happy mare sighed romantically and flopped back onto her creaking chair with her arms spread wide. A blush spread across her chubby cheeks at the memory of being pinned down by her much smaller beau. “My short king can put his fun sized party pole wherever he wants, whenever he wants!”

“But that means that Cheese is lying, just to... oh, never mind. Have you ever thought about what it would be like to play with a bigger one? You know, like my husband’s?”

“Why would I want a big one?” Pinkie asked quizzically. “I already have the best one!” She suddenly shifted in her chair, a frown coming to her muzzle. “Ooh, I hope Big Mac doesn’t make Cheesy cum so much that he can’t get it up for his after dinner blowjob! Pace yourself, honey!” she called out.

Sugar Belle was frowning as well, albeit for a very different reason. It had been a long time since Big Mac had shown as much interest in her plot as he was now showing in Cheese Sandwich’s. Mac was slapping and groping those taut orange boycheeks as he fucked his monstercock between them, grunting and drooling like a maddened animal, showing the submissive stallion the passion that had somehow gone missing from her marriage bed. When she’d first sighted the underwhelming erection Pinkie Pie had to work with, Sugar Belle had felt sorry for her co-worker... but now she had to admit she was a bit jealous!

“Pinkie, how many times would you say you and Cheese have sex in a week?” Sugar Belle asked with growing curiosity.

“In a week?” Pinkie wrinkled her muzzle. “I dunno, what’s 6 times 7?”

“Unfff, here it cums,” Big Mac groaned loudly, his hips moving with desperate speed. “Take it all, ya little cocksleeve!” All at once he buried his mighty cock to the root in Cheese Sandwich’s bowels, and leaned over the quivering body of his bound lover to cover orange lips with red, kissing the smaller stallion with desperate intensity. “Mmmphhh!”

Cheese Sandwich’s eyes opened wide and his once flat midriff bloated outwards as his insides were filled with hot, fresh horsey sauce. His tiny dick twitched and bounced, spitting a constant stream of pre, and it was only by the sheerest act of will that he managed to hold off a third sissygasm, preserving his next load for use as Pinkie’s after dinner treat.

“Oh sure, you’re happy to cum up his ass...” Sugar Belle grumbled at Big Mac.

With half shaded eyes Pinkie looked suspiciously over at her friend. Sugar Belle didn’t seem like she was enjoying what should have been the funnest girl’s night activity ever: watching her husband buttsex with another stallion!

“Hey, is there some sort of bedroom problem with you and Big Mac?” she queried nosily. “Maybe we could help!”

“Maybe you can, Pinkie,” Sugar Belle mused. “Maybe you can...”
