MKON-146 — My friend's little sister was a total sassy brat! She straddled me, called me pathetic, and milked me dry while making me lick the soles of her feet. - Hinata Yuna

Makoto finds himself alone with his friend's younger sister, Yuna, at her house. Yuna suggests a game where the loser has to do whatever the loser says, and Makoto loses. Yuna demands that he become her personal chair. Makoto does as he's told and becomes a chair, and when he gets an erection, Yuna looks at it and berates him. The next day, Yuna demands it again, and this time they have sex. He is milked dry and falls into slavery.
