Inside a women-only train car, a pure and unsuspecting girl is suddenly targeted by a predatory lesbian molester. Unable to cry out, trapped in silence and shame, her body begins to surrender to the pleasure she can't resist. The aggressor—a clingy stalker obsessed with young flesh—uses lewd, persistent touches to awaken the girl's sensitivity. Gradually, the innocent schoolgirl becomes addicted to the lesbian pleasure forced upon her, until she finds herself craving the very molestation she once feared. Hinako Matsui makes her lesbian debut in a tense and provocative scene.
