MUKD-398 My lewd little sister, Ai Mukai, tempts me. She skips school all day to have non-stop orgasms and secret internal sex with me.

Aoi Mukai, who is head over heels in love with me, started rubbing her ass against me from morning to provoke me. Once I got into the mood and started playing around, she was initially confused but gradually got that glazed look in her eyes and begged for 'more...'. Morning blowjob & mouth shot, uniform sex with internal ejaculation, masturbation in a swimsuit in the bathroom & facial, and finally, suppressing her voice so her parents wouldn't find out, she wore gym shorts and had internal ejaculation again. I thoroughly enjoyed her well-proportioned slender body. Stayed at home all day, having sticky sex.
