Tobias looked over his shoulder, licking the mess from his muzzle as he watched Kai. His breath hitched when Kai licked that sensitive opening, tail trembling more above. He'd never let anyone touch him in such a way, so he was very sensitive.

He shifted as Kai mounted him, the other wolf having much more muscle mass than Tobias. Otherwise, the pair were pretty even in size, with Tobias having a more lean build than Kai.

There was part of him screaming for this to stop, but raw instinct won, letting Kai push into him. He gave an odd moan-like howl as he was stretched open, his own cock throbbing between his legs, dripping his thick pre onto the floor below.

Feeling Kai start rutting against him, he gave a keening cry, the alpha's cock pushing so deep with each thrust. He was hitting nerves that Tobias had never touched, sending lightning up his spine. His cries only got more intense when Kai's swelling cock put more pressure on his prostate. His own knot began to swell, cock twitching as inner muscles clenched and spasmed around Kai. He bucked back into him, feeling that swelling knot pop in and out of him, waiting for the moment it would lock into him.
