Amidst the ruins of the Commonwealth, a horny vault dweller finds refuge in a vault girl's warm mouth. She deepthroats his cock, her tongue swirling around the head before she takes him deep, gagging slightly. She then climbs on top, impaling herself on his cock, her pussy stretching to accommodate his size. He grabs her hips, slamming into her until she screams, her orgasm triggering his own. They collapse, panting, before she turns around, offering her ass for one final fuck.
