He manages to knot you

Your eyes shut tight as the hyena continues thrusting, now with a bit more strength as he makes his intentions clear. You try to open your mouth and tell him no, there's no way you can handle his knot on your first time, but it's impossible for you to unclench your teeth; especially as a particularly hard thrust pushes the air out of your lungs. You crack your eyes open to see that the hyena's own face is completely lost in lust, his tongue hanging out of the side of his mouth as his hips snap back and forth at an increasingly rapid pace.

"Come on... open up... I know you can take it..." he says between thrusts, each time pushing forward a bit harder. You can feel the massive knot threatening to break through and enter you, but your ass refuses to yield, even as he deliberately slows his pace to try and make it happen.

Your ass feels like it's on fire as he stops thrusting entirely, dedicating all his strength to a forward push. "Almost... just a little... more..." he grunts out, and your mouth finally opens in a ragged cry as you feel yourself stretch impossibly wide, the knot finally managing to squeeze itself inside and lodge itself securely. With a victorious shout, the hyena begins jerking back and forth again, barely able to move more than an inch inside your impossibly stuffed ass. "Got it! See? That was easy, huh?"

*EASY?* you think bitterly to yourself as you slowly manage to catch your breath, struggling to deal with the new feeling in your ass. You feel the hyena's grip on your legs tighten as he grits his teeth, a thin line of drool dripping down onto your face as you feel his cock throb and twitch inside of you, moments before it floods your innards with cum. The breath you just caught is lost again as the unfamiliar sensation washes over you, your face burning red hot with embarrassment.

"Ha... there we go... that was incredible, little guy." the hyena says, tugging his hips backward and finding himself locked securely in place. "Oh... huh. Guess we're waiting a bit for round two, huh?"

You blink in disbelief. "R-round... two?" you ask, your voice hoarse and breathless.

The hyena grins. "Hell yeah round two! I said I'm gonna fuck you all day, remember? And I plan to keep that promise!" he says, tugging backwards again awkwardly. "Just, uh... as soon as you let go of me, anyway."
