Express Train to Ecstacy♥

Misuzu invites her boyfriend Yuto on a train journey, setting a tantalizing condition for their trip: they can engage in perverted acts, but only over their clothes, with no direct skin contact. The promise of this risqué game fills their ride with a charged, intimate tension.

Their forbidden play is violently interrupted when a sudden jolt separates the couple. In the confusion, Misuzu finds herself isolated and vulnerable, becoming the target of opportunistic foreign men on the train who begin to sexually harass her.
