The colt is only a few days old. The farmer gave it some grace enough for it to learn how to walk, to spend some time with its mother. To be happy and carefree. He was going to give it some more time, honest, but he’d finally caught that damned fox that had been eating his chickens. He didn’t want to shoot the poor thing, necessarily, despite knowing it’ll solve his problem, but it needs to go somewhere… He gives the colt a harsh smack on the ass when he reaches it, shocking the boy awake with a whinny. The farmer’s already rock hard in his jeans, his massive shaft throbbing down one of his pants legs. The colt’s ass is easy to spear a few thick fingers into, though the horse doesn’t like it. His preparation is perfunctory as he’s still got the fox’s scruff in his other hand. The donut hole throbs around the fat of his hand, four fingers thrusting in and out harshly. He looks at the fox, worryingly watching the view, before smiling. With the colt tied to a post and facing a corner, it has no way to escape the huge fist that’s forcing its way into his hole. His anus clenches and trembles, straining as it’s opened to new lengths. His fist bashes against the tight sphincter of the bend when it finally succumbs. His forearm is barely halfway in, but he forces it deeper, yanking his arm back before punching forward. Each punch he keeps pushing for long moments, hand curling into a fist to force the colt’s insides as wide and as quickly as possible. Soon his bicep is stretching him anew, hole as wide as his little thigh. The poor thing had been sobbing by now, it’s broken-in insides fluttering around his arm. He keeps his arm still, far too deep in a colt, just to feel him try and push out the intrusion, making no purchase. Timing it with an especially harsh clench of the bowels, he yanks his arm out as fast as he can, reverse punching his hole with abhorred wet slurp. Before he can recover, he jams the feral fox into his rectum too. The colt tries to kick in his panic, not succeeding in doing anything meaningful. The farmer uses his sloppy wet hand to push the fox’s ass as he forces it deeper. The fox’s fur is too dry for it to easily slip in, but the farmer doesn’t relent. With the colt’s need to shit out something impossibly big, and the farmer’s wet hand, he’s not too surprised when the fox’s anus loses the fight and eats up the farmer’s fist. Something about the force of it settling deep in the fox’s bowels as well makes the colt’s ass lose the fight, begrudgingly eating the fox. He carefully pulls his hand back, but the fox is already chest deep past the bend, being sucked deeper with every clench and cramp. Fuck, the farmer is so hard he hurts, dizzy with it. There’s an annoying baa-scream behind him. He turns, jumping a little to see one of his mini goats gazing up at him. “At him” is a generous statement, the animal's eyes seemingly looking everywhere but him. The farmer looks at the gaping hole of the colt. Well, he’s not going to get much friction there, and the fox will only be around the head of his cock by now… He snatches up the goat, not even caring about its scream of surprise when he thrusts into its ass. It’s not the first time it’s taken his cock, but he hadn’t been this rough before and he’d used lube other than his precum. It’s hard to focus on forcing his cock inch by inch deeper, the goat far too tight, with it screaming like that. The obvious solution is to force the goat into the open ass of the colt, muffling its cries. The colt squeals out his own displeasure, back arching. The farmer fucks the goat deeper and deeper until its shoulders are forced past the ruined hole of the colt. It probably hurts the fucker, the goat kicking and thrashing, the fox surely unhappy in its own regard. The hole of the colt, previously donut and plush, is now a thin, angry line stretched thin. The farmer grunts out something that should be calming under any other circumstance, for he’s not stopping until the hole has nothing to clench around. He doesn’t cum before the goat’s hips slide past the ring. Despite his horniness, he’s not even close, too wrung up, contradictory, to want to stop now. He takes long strides to the pen of mini goats not terribly far away, throbbing cock swinging with each step. Multiple of his goats try to suckle and lick at his wet cock but he doesn’t have time to entertain them. He grabs the nearest one, taking it with. The colt’s head is hung low, stamping his hoof while he cries softly. His ass is beyond ruined, beyond used up. It’ll surely never close even into adulthood… if the farmer has anything to say about it. The goat’s feet are still hanging out of his ass. The farmer could punch his fist inside and barely feel the colt’s walls, he’s sure of it. His belly is around and thrashing like he’s pregnant. He’s about to be pregnant with triplets, the farmer thinks with a vicious grin. He lifts the goat in his grip above his cock, unkindly dropping it down in a seconds notice. The goat, immediately mindbroken in its pleasure, trembles around his massive shaft, the head of it bulged past its chest. To get some of the pent up aggression out, he fucks the goat’s tight passage for a couple long minutes, watching the horse try to push out something far to big and heavy. god, he can see the first goat’s gaping asshole from here! He can’t wait. The colt’s head shoots up in surprise when, after barely pressing the head of the second goat past his bruised hole, the farmer forces its body in, past the shoulders, past the bulging belly. He grabs the colt’s hips as he bashes his own hips into the goat’s. The colt is too full, no more space for two goats and a fox, but the farmer makes it work anyway. He fucks harder, bruising and pummeling the goat’s entire intestinal tract, simultaneously forcing the colt’s own insides to spread to impossible levels. His intestines are stretched further than any colt’s should be, wrung out until they have no elasticity. The farmer sees white when he cums, spending multiple long minutes shooting out thick, heavy loads. He feels it fill the second goat, bursting through its mouth, then into the first goat who must have the second’s head up its own ass, the first goat's belly bulging as well. The fox is drowned in cum, surely forced to gulp down the thick seed while it’s stuck in the colt. When he pulls out, the second goat’s ass slowly slurps into view, the natural pressure of the horse’s guts pushing it out. Well he can’t have that, this colt is now his storage! The farmer looks around. Ahhh… His mother is nearby, her own ass filled with a dildo she struggled to take. She’s not the biggest horse, but she’s not small either, and certainly isn’t the dildo stuck in her ass. He hooks his thumbs around her anus, wrenching her open. She neighs, jumping a little. The surprise does just what he wants, has her pushing out the bulbous dildo from deep within her guts. He watches it appear from the wrinkles of her moist flesh, the dildo with far too small of a base emerging from the depths. With her so stretched open, the big knot at the base pops free with another body-tightening spasm. It’s hard to get a grip on it, but he pulls with his whole weight to tug it free. The rest of the arm-thick shaft falls free, the horse lightly squirting all over him. He pats the sore hole none-too-gently, commenting how he’s surely gonna take care of her in a moment. The colt is trying to push the goat out of his ass, impressively poorly, the farmer thinks. He sees his entire belly clench and writhe with each rolling cramp, the gaping goat ass pushed out an inch before the colt runs out of energy, the goat being slurped back in multiple inches deeper. The farmer coos that he won’t have to worry in a bit, giving the colt an even meaner slap right over the hole. He thrashes, crying out anus tightening and only making the goats and fox sink that bit deeper inside. While the colt is going through the motions of that, the farmer braces the dildo against his pelvis, knowing he’s gonna need the support. The head pops on easy enough, the shaft the perfect size for the horse’s gaping hole. The anus flutters around the shaft, squelching as it tries to push. The farmer takes some sick joy in watching it pulse in and out. Just as one of the goats thrash inside, leading the colt to tighten bodily once again, the farmer forces it forward. It doesn’t sink in very fast immediately. It’s a slow, debilitating procedure. It has to force its way into one of the goats, then through that tight channel, then out the goat’s mouth into the first one’s stretched colon. Then there’s the knot. The knot is almost as big as the colt’s head, and surely still too big for the colt. The farmer doesn’t much care though. He pulls the dildo out until it slurps back down the goat’s throat, grabbing the colt’s hips before throwing his weight into the thrust. The colt screams, voice giving out partway. Alas, the knot isn’t inside yet, but his anus is bruised an ugly, hot purple. It’s gaping disgustingly around the thick shaft, insides threatening to come out with it. The second thrust is much the same, despite the farmer pulling the colt back into the thrust and keeping the pressure firm for a long, long moment. It’s close though, the hole sucking on the beginning of the knot. He adjusts his stance, clutches to the horse’s hips before forcing it forwards again. He watches with a wide, toothy smile as the hole begins to spread. This toy is definitely too big, but it’s still making purchase anyway. the colt panics from the pain, the over filled colon. Hahh, maybe the fox is in the small intestines by now, it must be. Either way, with the colt’s thrashing, the hole spasming around the impossible girth, it very, very, very slowly takes it. It doesn’t even pop in when it passes the thickest part, the horse (and goats) too full. The farmer still has to ease it forward cruelly until it settles impossibly deep. He thinks for an annoying moment that the horse, ass too ruined, is just gonna push it right out when the farmer pulls back… but his donut hole, now stuck as a thin ring, covers the knot as it stretches around it, asshole stretched and pulled tight. The farmer smacks his haunches, saying he’s got other things to do and that the colt can surely be content with sitting here. Actually, he changes his mind. He unties the poor fella, letting him stumble off into the pasture. The farmer knows the colt won’t be able to relax any time soon with all that up his ass.
