Rina, a female college student, arrives alone at a stylist's office for her first modeling job. After successfully completing her first day of shooting, she is discussing her next job while drinking alcohol, which she has just learned to drink, when she suddenly realizes that she is alone with a male staff member and becomes extremely Kokoro. When the man starts to sexually harass her, she denies it with a laugh, but the man doesn't stop. When he forcefully strips her of her clothes and sucks on her nipples, the voices that she had been refusing to make stop and she starts to sigh. In the cowgirl position, Rina feels so good that she starts shaking her hips up and down, saying "It feels good~".
