Graduation Molester Train follows a lonely, resentment-filled man haunted by memories of his high school teacher, the alluring Nakajima Nanoka. Years later, he spots Nakajima Kanoko—a petite, baby-faced woman with massive breasts and hips who strikingly resembles Nanoka—on a train. Convinced she's his chance to reclaim lost desires, his long-suppressed fantasies erupt into action.

In his delusional world, the teacher figure aggressively seduces and dominates him with sultry advances. In reality, he becomes the aggressor, groping and violating the unsuspecting woman amid packed commuter crowds. The series alternates between these contrasting dynamics, catering to both submissive and dominant tastes in one package.

Each episode escalates the encounters: from initial targeting and fondling to drunken vulnerability and full-on non-consensual acts, culminating in a twisted confrontation where delusion fully invades reality. Packed with creampie, facial, big tits/ass focus, and molestation themes, this censored OVA adaptation of a popular CG set delivers intense, repetitive "rides" on the fantasy train. Released across 2020 in four parts, it's a niche gem for chikan and teacher fetish enthusiasts.

Based on the CG collection by Urakaryuu (裏火竜).
