Ezreal inhales sharply at the unexpected slap, his butt tensing briefly but damn that felt good. He rolls his eyes at the other's confidence but he actually is hoping he isn't all talk and he leans toward believing that he can back it all up. He wiggles his ass at the bite, a bit impatient but at least the other is soon spreading his cheeks.

He tilts his head back when Kayn's tongue starts licking to his hole and he sighs at the pleasure of it.

"Good boy," he hums.
