One day, a transfer student came to our school. It was the gravure idol Takasho! The very naughty transfer student tempts students with her panty shots, shows off her boobs in gym class, and shows off her body line in a competitive swimsuit at swimming club activities, driving them crazy! Not only students but even teachers are seduced by Takasho's devilish temptations, and even though they know it's forbidden, they have secret meetings and have impure sexual relations! She makes bold friends by making full use of her big breasts!
