How could Ezreal not be close after Kayn had been eating his ass out like he was starving and then fucking him like this? He shudders beneath him.

"We'll see if you can live up to your big talk," he pants, instead of answering that yes he's close. He's so fucking close. But he can't hold back any longer after that, the other's relentless thrusts pushing him over the edge and he comes, tightening around the other's cock and trying to press down against the bed with his hips to get more direct friction on his cock.
