MKON-146 · My Friend's Little Sister Was a Bratty Mesugaki! Ridden and Insulted While Being Milked Dry - Yuna Hinata

Makoto finds himself alone with Yuna, his friend's little sister, at his friend's house. At Yuna's suggestion, they play a penalty game where the loser must do whatever the winner says, and Makoto loses. Yuna demands, "Become my personal chair." As Makoto obeys and becomes her chair, Yuna notices his erection and begins to mock him while admiring it. The next day, Yuna approaches him again, and this time they have sex. He is milked dry with spurts of cum, falling deeper into being her slave.
