The stallion smirked, squeezing the donkey’s backside, smooth with grey fur and impossibly soft. A donkey’s coat was thicker than that of a horse, better for dispersing heat in hotter climates and terrible at keeping them dry in wetter climates, but it was just right for him as he slid the fat length of his meat over that backside. He groaned out loud, tail flicking, but the chestnut stud stallion had so much more to give as he bent the slutty donkey over the gym bench.

“Oooohhh,” Cody, the donkey moaned, a bray lurking in the back of his throat. “Please… Fuck me… Fill me…”

Dripping with lust, he moaned and moaned, wanting it so badly, not caring that the gym was not empty, his cock out and hard. It was a comparable size to the stallion’s, but Chester was not about to let him take the top position, not when he was layered with sweat and hot after a workout, a heavy chest session having rendered his muscles pumped and hard. No, that was for him, for the mottled grey and pink length of his shaft, his sheath grey and pulling back from the base of his cock as if every inch of his dick wanted to be out and free of it.

Cody braced his paws on the ground, hoof-like fingertips scrabbling for purchase on the rough gym matting, over the long side of the bench and grateful for the padding. Yet he wanted the thickness of that cock pushing up into his tail hole more, stretching him out, the head catching and the weight of the stallion behind it coaxing inch after inch inside. They didn’t even need to share any lube between them, pre-cum drooling from the head of Chester’s cock, slickening the path for his dick to grind up deep inside the donkey’s backside.

Someone passed behind them, making a crude comment as they went on their way to complete their workout, but neither Chester nor Cody heard it. It was all well and good at their gym as long as no one engaging in “extra” activities got in the way. But Cody would not be quiet as Chester thrust, forcing him to take over half the length, up past the medial ring, grinding in harder and faster, finding a pace with his thrusting hips.

“Fuck… You’re tighter than last time…”

Chester’s heart pounded harder than it even felt that it did in the middle of a set, muscles burning, going to failure, though there was no failure to be had when he was balls-deep inside such a slutty tail hole. Grabbing Cody’s tail, he yanked it to the side out of the way even though there was really no need to, his cock plunging deep, swallowed up by that greedy arse.

Huh. Chester smirked. He really was an ass, but one in the best of ways, hips working, thrusting, powering into him. The bench rocked and bumped back into the floor as he was shifted, but Cody was powerless to call a halt to anything, the ache and throb of his own cock desperate for that ultimate release. Whether or not it would come, however, while his backdoor entrance was being filled was another thing entirely, but one that both of them were keen to find out.

Thrust after thrust… Oh, there was nothing like that stretch, so tight around the stallion’s cock that he had to keep going, had to keep thrusting, not having anything else left in him where he at all felt like he could stop or slow. He had to grind back, scrabbling for purchase on his hooves the best he could, Chester demanding more and more from him, always more.

Chester grunted, a hot wash of breath pouring over the back of the donkey’s neck even with the space between them, his snort had that much force behind it.

“Huff… You think you can take it all… without any slopping out this time? Nice and… unff… tight…”

Cody only had a moan by way of reply as the stallion’s thrusts sped up and up, not caring to draw anything out or show a touch of stamina, intent only on going and going again. Round after round would be his to take as he thrust and humped, letting the power of a stud stallion course through him. With every snort and puff of breath, more and more pre-cum drooled from his cock, yet he would not stop until sweet completion of his, the slap of his hips on Cody’s arse resounding through the gym.

Yet it was Chester that reached his high first, grinding in deeply, his sheath pushed back with how deep he thrust, caring only for his pleasure. It was a good thing that the donkey’s swept up and along with his, moans mingling, pre-cum easing the path of his cock as he thrust shortly and sharply, staying as deep as possible. The stallion gave one final grunting groan, head thrown back – and then there was no going back as the first splattering rope of his cum poured forth.

Cody gasped soundless, lips parting, yet was too caught up to care, hips working, pumping, slamming himself back onto that hot length as if there was nothing else left for him. He could only think of how good it felt to be strained tight, his cock dropping a hot load on the gym floor, splattering with mess, need rising, curling into Chester’s.

Leaning back, the stallion dragged his rump along with him, rammed deep, not allowing a single drop to escape, though it meant that he could not thrust as powerfully as he liked. It was one trade-off for another and something that he was going to have to allow, panting heavily, mouthing the air even though he could only breathe so sharply through his nostrils. The slick, hot deluge of cum had only one place to go, sinking deep into the ass’ slutty backside, the donkey moaning lowly as his head hung, cock drooping, softening.

“Oh… Oh, god…”

Chester grinned.

“And that was just the first.”

One would always know, intimately, when they had been taken by a stallion.

Chester made sure of that.
