The scent of his own musk fills the air as he indulges in his private ritual. His hand moves expertly, knowing just the right pressure to apply. He imagines a lover's touch, a fantasy that makes his cock throb. The room fills with the sound of his pleasure, his moans echoing off the walls. He's close, so close, when suddenly, he hears a noise. Someone's entered his space, intruding on his most private moment.
