Adult role-play: Kazuya secretly buys a computer and stumbles across an adult website featuring a woman whose eyes are censored but who otherwise looks exactly like his mother. Her recent suspicious behavior fuels his fantasies, and he becomes increasingly aroused as the lookalike is trained by a middle-aged man she calls “Master.” When the site begins showing extreme BDSM sessions, Kazuya can no longer shake the thought that the woman might really be his mother.
