While their parents were away, my NEET brother forced my cheeky sister-in-law to be supervised and thoroughly clothed Yuna Ogura
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 2 nights and 3 days, I gave her younger sister ●●●● and carried out ●●●. She was thoroughly supervised from that day until her parents returned. She trained me until she obeyed me.
