Kai grins around a mouthful of blood, swallows and pants open mouthed at the way Kurt shudders and shivers and squeezes around his cock, nestled up against Leo's, throbbing and dripping and ready already to burst. He could come right then, thrust as deep as he can and knot their little mate that exact second, feel his spend drip out and down their legs and into the grass, joining the mess already there -- but that would mean Leo would win. And Kai can't have that.

So instead he rocks his hips up hard, grinding forward against Leo, pressing close enough that he can feel Kurt's heart rocketing through their ribs, in time with his. "You know better'n anyone how good I can wreck someone, Leo," he growls, suddenly pulling the sobbing, shuddering human away, feeling the slick gush down their thighs as his brother's cock slides free. Kai's still inside, stays there as he moves onto his back, settling Kurt over his hips, guiding their shaky hands to brace on his chest before he drops them onto his cock fully, sheathed to the hilt, hips smacking against their ass.

A couple more thrusts, bouncing Kurt on his cock, then Kai grips their come-streaked cheeks and spreads them wide, grinning up at Leo. "C'mon, big wolf, get on top. Just this once. Help me make our little bird wail." His big hands dig into Kurt's pale, freckled flesh, hard enough to bruise, making him vaguely wish that he'd put his claiming bite right on their plush ass instead. But Leo's already moving forward, guiding his cock through the mess of come and up against Kai's, then sliding inside Kurt again, making both wolves all but purr in satisfaction. The angle is deep, Kai never moving more than a couple inches out of the young human, Leo staying just as deep, both of them grinding together for a long, punishing moment.

Then, like they'd both silently decided it, both cocks slide free, almost entirely, then thrust back in hard and quick and deep.
