MASM-018 友達の妹が清純そうに見えてクソ生意気なメスガキだった！敬語で「ざこち●ぽですねぇ」と罵られて大人のプライドを打ち砕かれて逆レ搾精されまくった 由良かな

At a friend’s house, I get alone with my friend’s polite sister Kana-chan and decide to play a game together. I was upset by the proposal for a punishment game in which the loser would listen to whatever he had to say, and I ended up losing. I was wondering what kind of cute commands my little sister would give me, but she smiled and said, “Please get naked.” She seemed innocent, but she was a super sadistic girl wearing a J-type skin! He made erotic demands one after another in honorific language, and the hellish days of being squeezed like a raw dildo began.
