Anno is a teacher who is very serious, but because of his stern appearance, his students call him Schwarzenegger and fear him. Ai and Aoi comfort Megumi, who is afraid of Anno's classes, and are a friendly trio, but in fact, Ai and Aoi are working part-time jobs as a sugar daddy, with actual sex, without Megumi's knowledge. That day, Aoi receives a call from her sugar daddy, and she declines to hang out with Megumi, saying that she has a part-time job. However, Aoi is reluctant because of the persistent contact from the man. Then Ai urges her to leave it to her and Aoi makes up an excuse to go home. After changing into her uniform, they visit the hotel room where they are supposed to meet, and when Ai tells Aoi that she is not feeling well and wants to leave it to her, Aoi asks her to stay in the room and watch the play. She reluctantly watches her best friend's sex as a spectator, and Aoi is astounded by her overly enthusiastic daddy. As soon as the fight is over, Aoi drinks an aphrodisiac and instantly recovers, leaving her astonished again, but the loud, lewd sounds he makes make her crotch a little wet. Will Aoi be able to get home without being touched, and will Anno find out about their sugar daddy activities?
