Kanae (Mia Masuzaka), an office worker, witnesses a junior colleague being molested on a commuter train one day. Despite Kanae's worries, her junior said unbelievably, "I was scared at first, but she got wet because it looked like she was being raped by a wild beast." Kanae tightens her guard and tries to protect herself from her molester, but the beast can't miss Kanae's big tits. While she is relentlessly played with on the train going and returning, she can't help but pervert Kanae's body.
