MASM-018-Uncensored-Leaked — My Friend's Little Sister Looked Innocent But Was A Damn Sassy Little Brat! She Insulted Me With Polite Language, Saying "You're Such A Pathetic Little Cock," Shattering My Adult Pride, And Then She Reverse-Raped Me And Milked Me Dry. - Yura Kana

I was alone with my friend's polite younger sister, Kana, at her house, and we decided to play a game together. I was flustered by the suggestion of a penalty game where "the loser has to do whatever the loser says," and I ended up losing. I wondered what kind of cute command she would give me, but instead she smiled and said, "Please get completely naked"... Huh? The girl who seemed so innocent was actually a total sadist hiding behind a J-pop idol persona! She kept making one erotic demand after another using polite language, and my hellish days of being used as a living dildo and having my semen milked began.
