[Chinese]NKKD-126 A record of non-stop sex with my kind sister-in-law during my serious brother's two-night, three-day business trip. Sakusakihara Rin

I'm a ronin student who lives like a free-roam in his brother's apartment. He had an unscrupulous feeling towards a woman's body. One day, my brother went on a business trip to the countryside for two nights and three days. 72 hours alone with my sister-in-law. I exploded the emotions I had been putting up with until then, and during the three days my brother was away, I spared no time to sleep and had sex with my brother-in-law.
