Aika is a fashion model by day. She is a popular pretty gal at the lounge by night. She is kidnapped on her way home from work and wakes up to find herself in a prison with men in black suits... "You're so pretty, we want you to be our toy." They give Aika a powerful aphrodisiac and take away her reason as she tries to escape. She loses her sense of self as she is repeatedly raped like a toy in gangbang sex, and the more semen she is showered with, the more lustful she becomes.
