Eina Satsuki, who takes the name of genius as she pleases, is also a genius at cowgirl position. The flashy hair-changed woman has an obscene strength like that of someone from Su○Sa○i, making her an erotic warrior. As soon as she sees a man, she uses her long tongue for a kiss that makes it impossible to breathe, immediately making him erect. She then straddles his dick and moves her hips in a riding position that is beyond description, truly a genius. Ordinary sex isn't even sex. This is the real SEX, taught by the genius Satsuki Ena. Warning: Excessive withdrawal.
