Mami Yamamoto, 22 years old. I'm a dodododo M, looking for the "ideal sadist", and today I'm going to put my body on top of a self-proclaimed S-man, but... I failed again. It's hard to meet the ideal person. "It's an illusion," says Tezuka, a college junior. He looks dumbfounded at me complaining while drinking alcohol at an izakaya. Tezuka is younger than me, but he's steady. Our hobbies match, and he's a good guy that I don't have to worry about. He has a nice face and is probably popular. But this guy... "Well, Tezuka, who's a virgin, won't like it." Yes, he's a virgin. I don't feel like doing anything to a virgin partner no matter how nice my face is. I should have thought... For some reason, when I was about to take the drunk Tezuka home at a faster pace than usual, her vision suddenly shook and she was pushed down. "You're always a virgin , don't you think?" The understanding from his junior, Tezuka, who thought it was, doesn't stop no matter how much she orgasms...
