[Reducing Mosaic]STARS-952 While the parents were away, a NEET brother raped, imprisoned, and thoroughly subjugated his clingy stepsister. Yuna Kokura

Due to her parents remarriage at an advanced age, a gal suddenly became her sister-in-law. Naturally, she didn't get along well with my girlfriend, who was a shut-in and a NEET, and he looked down on her, which made her resent him. One day, when her parents went on a trip for 3 days and 2 nights, they gave her sister sleeping pills and raped her. She was thoroughly confined and trained from that day until her parents returned. I trained her until she obeyed me.
