MASM-018 My friend's little sister looks innocent but is a fucking bratty bitch! She insulted me with polite language, saying 'You're such a loser,' shattering my adult pride and making me cum over and over again in reverse. Yura Kana

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.
