Kanae, an office lady (Mia Masuzaka), one day witnesses her junior colleague being molested on the commuter train. Despite Kanae's concern, her colleague astonishingly admits, "At first, I was scared, but it felt like I was being ravished by a beast, and I got wet." Determined to protect herself, Kanae tries to guard against the molester, but her voluptuous figure doesn't escape the beast's eye. As she's persistently toyed with on the train, both coming and going, Kanae's body gradually becomes dependent on the molestation.
