Miu Tsukishima is a fair-skinned, innocent-looking 21-year-old who says she has sex with her boyfriend three times a week but has never used a vibrator. Short on money, she applies to a modeling agency and is gradually pushed into more explicit demands while being assured no one will find out. She nervously experiences her first vibrator orgasm, then gets offered money for sex. Trying to stifle her moans as she feels every thrust, she is finally told she could be a star before receiving a creampie.
