Our protagonist is a run-of-the-mill businessman in his late 20s with no girlfriend. There is a cute HS girl he sees on the train every day. She’s well developed, with nice hips, and a healthy figure. If only he could marry a woman like her… With that figure and kind personality, she’s given up on struggling and gives into being molested or fucked. That is all she’s known. One day our protagonist molested her on the train. When she didn’t struggle, he brought her to a hotel for sex. This would be the first time she has had normal sex. That’s when she learned how good sex can be, and he learned about her tight ass and voluptuous tits, her family-oriented and nice personality, and how she’s a dirty girl. They fell in love with each other, and their sexapades escalated.

The spot that if pressed will make any woman a slave to sex, the “sex switch.” Oshio Tsubohachi is a master at seeing those spots, and making women beg for his cum. A high school girl who goes to the toilet to get fucked by multiple men even when she has a boyfriend. A school president begging for a creampie.

She was part of the track and field team and was working hard practicing for the tournament coming up. But all she could think about was her crush and fellow teammate Makiyama. She touched herself thinking about him every night, imagining herself with him. One day he caught her while she was caught up doing lewd things saying his name… He was a salaryman who decided the best way to keep his body active was to join a local swimming center. Someone had been stealing men’s underwear and he just so happened to walk in on her as she was doing it…his swim coach! She said he could do anything he wanted to her as long as he didn’t tell anyone…
