Unaware of her own actions, the swimming club idol, Rinyu Yumino, is repeatedly gang-raped by her male club members after her large breasts are exposed in her competitive swimsuit, causing everyone to lose their rationality. (DASS-241)

To pursue his idol activities, he decided to quit the swimming club, but please keep it a secret. He'll do anything, using his cute face and his tongue to perform oral sex. Every day, he'll be used as a giant-breasted sex toy, being thrust into and joined in the fun in the swimming club's pool, squirting endlessly. Wearing a sexy swimsuit with holes, he'll be forcibly penetrated, violently given oral sex and have his breasts kneaded in the locker room, his face covered in semen. He'll be smeared with grease, his breasts shaken, finally nearing orgasm! Although he doesn't want to, his body reacts, he loses his mind, and indulges in rape.
