The wolf shoved the fox down onto the padded mat in the middle of the playroom. "Rules are simple, bitch. You lose the game, you stay tied till I say. First one to shoot without permission gets the full treatment."
Rex, the big gray wolf, already had the leather cuffs ready. His cock hung heavy and half-hard between his legs, thick sheath pulled back. The fox, named Kit, grinned up at him with that cocky little smirk, tail flicking. "You talk too much. Strap me down and let's see who begs first."
Kit stripped fast, dropping his shorts. His lean, red-furred body was already twitching, pink cock starting to poke out. Rex grabbed him by the scruff, forced him onto his belly, and buckled the wrist cuffs behind his back. Thick straps went around his thighs next, spreading them wide and locking them to floor rings. A padded collar snapped around Kit's neck and clipped to a short chain on the wall so he couldn't lift his head much.
"Game starts now," Rex growled. He ran a paw down Kit's back, squeezed one furry ass cheek, then shoved two fingers straight into the fox's hole without lube. Kit grunted, hole clenching. "Fuck, you're already wet inside. Slut."
Rex pumped those fingers hard, twisting, stretching. Kit's cock swelled fast against the mat, dripping. The wolf pulled his fingers out, wiped them on Kit's tail, then grabbed a thick silicone plug. He worked it in slow, making the fox feel every ridge until it popped past the ring and sat deep. Kit whined, hips rocking.
"Round one," Rex said. He flicked the plug's base, making it buzz on low. "You gotta hold it without coming while I tell you exactly what I'm gonna do to you."
Kit tried to talk shit back but the collar kept his muzzle low. Rex leaned in close, voice rough. "I'm gonna fuck that tight fox ass raw after I edge you for an hour. Gonna knot you so deep you feel it in your throat. Then I'm switching the plug to high and leaving you here while I watch."
The buzz kicked up a notch. Kit's cock jerked, a string of pre stretching to the mat. He cursed, body straining against the straps. Rex laughed, low and dirty, and started stroking his own cock right in front of the fox's face, letting the head brush Kit's muzzle.
"Smell that? That's what you're getting if you lose."
Kit lasted maybe ten minutes before he started begging. "Turn it off, you fucker. I'm close."
Rex turned it higher instead. The fox howled, hole pulsing around the plug, cock throbbing untouched. He didn't come, but it was close. Rex unbuckled the thigh straps just enough to flip him onto his back, re-secured them spread wide, and climbed over. He slapped his heavy wolf cock against Kit's face, smearing pre across the fox's whiskers.
"Open." Kit did, and Rex fed him the whole length, fucking his throat in short thrusts while the plug kept buzzing. Spit ran down Kit's chin. Every time the fox gagged, Rex held there, balls pressed to his nose.
When Rex pulled out, he grabbed the lube and slicked his cock. "Round two. I fuck you slow. You come, you lose and I add the blindfold and earplugs for round three."
He yanked the plug out and replaced it with his cock in one thrust. Kit's ass took it, stretched and ready. Rex fucked him steady, deep, grinding the knot against his rim without pushing in yet. One paw wrapped around Kit's cock, stroking in time. The fox babbled curses and pleas, hips bucking as much as the bondage allowed.

"Don't come, don't come," Kit chanted, but his cock was leaking steady now. Rex leaned down, bit the fox's neck above the collar, and growled right in his ear. "Gonna fill this hole. Gonna breed you like the game slut you are."
Kit lost it. His cock pulsed hard, shooting thick ropes across his own belly fur. Rex kept fucking through it, using the clenching hole until he was right on the edge, then pulled out and painted Kit's chest with his own load.
"Game over," Rex said, voice satisfied. He left the fox tied, added the blindfold and earplugs like promised, and cranked the plug back in on high. "Round three starts when I feel like it. You just lie there and take it."
Kit twitched and moaned, already hardening again, completely at the wolf's mercy. The game wasn't over. It was just getting started.
