In this adult role-play, Kenji stays with his aunt Chisato, whom he has secretly desired for years, until he can find a room of his own. Living alone under the same roof with the woman he adores sends his excitement soaring. Driven by lust, he sneaks into the changing room and uses her freshly removed, still-warm panties to masturbate. As he revels in their rich, sweet scent, Chisato catches him in the act.
