I'm A Mourning Woman, But I'm A Man Who Does It. A Memory Of One Summer When My Sister-in-law, Who Lives A Self-indulgent Life, Realized How Much She Fell In Love With Me And Allowed Me To Have Sex With Her For One Night Only. Hikaru Minazuki

I have a stepsister who lives a dissolute life every day. Sometimes she brings men she picks up on dating apps into her room, seemingly to satisfy her sexual desires. I... love that slutty stepsister of mine. One day, when I confessed my feelings to her, she allowed me a one-night stand. Hey, sis? Between the rough guys from the dating app and me... whose sex felt better? 'Produced and copyrighted by KM Produce Co., Ltd.'
