The shower curtain billows as the girlfriend's firm ass presses against the glass, her boyfriend's hands roaming her slick body. She turns, her breasts heaving, and slides down his length, taking him deep. The water pounds on their entwined bodies, their grunts echoing in the enclosed space. She leans back, her headtilted, eyes closed, as he thrusts into her, the hot water mixing with their sweat and juices, their bodies sliding together in a steamy, passionate dance.
