A lone, adventurous man explores the extremes of his urethral fetish, inserting a thick, curved toy into his piss hole, fucking it in and out with intense, measured strokes. The toy's head stretches his urethra, sending shivers of pleasure-pain through his body. He lubes it up, pushing it deeper, his moans echoing in the silent room. He switches to a plug, massaging his prostate, before returning to the toy, fucking himself harder, faster, his cock rock hard, pre-cum leaking.
