Horny and alone, a man seeks quick relief in the bathroom. He locks the door, pulls out his hardening cock, and begins to stroke. The tight space and the thrill of potential discovery heighten his pleasure. He imagines the eyes of an unseen observer on his body, making his strokes more urgent. The sound of water running through the pipes masks his groans as he nears climax, his hand moving faster until he finally spills his load into the sink.
