A popular rental apartment building in downtown Tokyo with access to three train lines. There is an apartment manager who has controlled many female residents through hypnosis. This summer's targets are two beautiful sisters who have been living there for a year. Day 1 When I got excited talking about yoga, I hypnotized my younger sister, and now she invites me to her room like a lover. Tonight, I'm going to enjoy Aise with the pretty hypnotizing doll in a yukata. Day 2 Using his younger sister, he enters his newlywed older sister's room. In the process of sharpening his five senses under the guise of yoga meditation, he imprints sexual sensations, fainting, and false recognition, and erases her memory. Of course, he doesn't forget to use a post-hypnosis technique that's a little different from the one he used with his younger sister... Day 3 I didn't expect the drunk older sister's husband to be attacked by the horny younger sister, but I thought of something interesting. I'll increase the older sister's Kokoro and peek into the sisters' true feelings. Oh, but in exchange for giving the husband a good time... Day 4 Under normal circumstances, my sister would not congratulate me and Lennon. I made her understand the situation by repeating it repeatedly while conscious, and then I completely brainwashed and controlled her body and mind, which refused. "This apartment is under my control." Tomorrow, and the next day too...
