Under the cover of darkness, a curious hand wanders, seeking forbidden pleasures. He oils up, his fingers slick as they delve into his tight ass, stretching and probing. His moans fill the room, echoing off the walls as he fucks himself with increasing fervor. His cock is hard, leaking pre-cum, but this isn't about him, not yet. It's about the intense, delicious pressure building inside him, the sensation of being filled, of being used. And when he finally can't take it anymore, he'll fuck himself hard, chasing that release.
