In the privacy of his room, a mature man dons his roommate's panties, feeling the soft fabric against his skin. He begins to stroke his hard cock, the panties tightening around his balls. His breathing deepens as he watches himself in the mirror, jerking off with increasing urgency. He reaches around and fingers his asshole, the sensation sending waves of pleasure through him. His body tenses as he nears orgasm, and with a final stroke, he cums, the thick streams landing on his ass and the panties.
