Betrayed by her crush, a female college student named Yayoi Hamabe is repeatedly abused in an organized pleasure club. (FNS-210)

Invited to a drinking party by a senior member of her club, she found herself the only female participant. Just as she thought the party was about to end, her senior handed her a mysterious drink, saying, "It's about time you tried 'that'!" This marked the beginning of her tragedy. After consuming the drink containing some "impure substance," her consciousness became clouded, but her sexual sensitivity became heightened dramatically. She would reach orgasm at the mere touch, and experience intense climaxes upon penetration. This was an unforgettable sexual experience, and a tragic story of a female college student who continued to have sex until the end of her life.
