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.

Miyuri is a landlord who has sex monthly with the tenant of one of her beat-up apartments, Daisuke. Showing up in a business suit, Miyuri ends up helping Daisuke study. But, getting excited from Miyuri’s plump thighs covered by stockings, he ends up ignoring studying and getting a foot job from Miyuri. Getting teased, he ends up being more forceful with Miyuri than usual. Miyuri changes into a lab coat to give Daisuke a physical education lesson. Bad kids get direct attention from the teacher using her body. “Today we’re going to learn how to be gentle while having good sex!” Swapping out a textbook with her body, Miyuri teaches Daisuke all there is to know about her dripping, sloppy pussy.
