[Reducing Mosaic]MKON-146 My friend's little sister was a fucking bratty bitch! I got ridden and called 'You piece of shit ww', made to lick her feet, and had my cum milked out. Hinata Yuna

Makoto ends up alone with his sister Yuna at a friend's house. Following Yuna's suggestion, they play a punishment game where the loser has to obey anything said by the winner, and Makoto loses. Yuna demands, "Become my personal chair." Makoto does as he is told and becomes a chair, getting an erection, which Yuna notices and starts insulting him. The next day, I was pushed by Yuna again and ended up having sex. She milked me dry with a squirt, and I fell into her hole.
