Ayano is a married woman secretly working part-time to save money without her husband's knowledge. One day, while riding the train, a post she made on a certain website revealing her hidden desire for molestation is discovered by a man, who then sexually assaults her. Confused by the experience, she becomes aroused and wets herself—having been suffering from a sexless marriage. From that moment on, she becomes addicted to being molested by strangers in public places.
