After being dumped by her crush, Kanoko's binge eating has led to weight gain and skin problems, and she decides to take action. She renews her contract with the nutritionist she hired a few years ago. While the teacher has a strict and overbearing attitude, Kanoko trusts him for his accurate advice and vast knowledge. One day, the teacher makes a surprise visit to her home. From that day on, something strange begins to happen to Kanoko's body...

One day, she wakes up from a mysterious, unfamiliar drowsiness to find the "teacher" with an expression she's never seen before ravaging her body... "There's no way that teacher would do something like this..." She climaxes quickly as her nipples, clitoris, and G-spot are stimulated simultaneously, and she cries in shame as an extraordinary penis is forced into her. However, once she finds out that she has been violated so many times while she was sleeping, her body obediently accepts the teacher... What is the purpose of the personal nutritionist? What will be the outcome for these two mismatched people...? We think that fans of love, mutual sympathy, and happy endings will also be satisfied!
