MKON-140 I ended up alone with my friend’s younger sister and felt awkward, but she turned out to be a real little troublemaker!! Insulted as too weak, I was pushed around and made to give in, with Karin Kitaoka

Satoru ends up alone with Kaori at a friend’s house. At Kaori’s suggestion, they play a penalty game where the loser has to obey any request, and Satoru loses. Kaori then demands that he become her personal chair. Satoru follows her instructions, and Kaori notices his arousal, teasing and scolding him. The next day, Kaori pressures him again, and this time they become intimate. He is thoroughly drained and gradually falls under her control.
