A solo boy's session takes a surprising turn when his girlfriend walks in on him. Instead of leaving, she stays, offering to assist. She guides his hand, helping him stroke his throbbing cock, before taking it into her mouth. She sucks and licks, her eyes locked onto his, as he fucks her face. She then moves down, using her tits to slide his shaft, bringing him closer to the edge. His body tenses, and with a final thrust, he cums, his load splattering onto her, marking her as his.
