In a grimy, dimly lit room, the man watches, his cock hardening as his girlfriend eagerly takes another man's dick into her mouth, sucking it with a hunger he hasn't seen in months. She moans around the stranger's cock, her own pussy aching with desire. The man can't help but join in, pushing his girlfriend's head down further onto the other man's cock while he penetrates her from behind, their bodies slapping together in a raw, desperate fuck.
