Having an affair with her lustful sister-in-law Aika Yumeno. One day I caught my sister-in-law Aika watching adult movies on the TV in front of the bed, lying face down with her ass turned around while wearing a dress. This made me unable to control myself, I wanted to fuck my sister-in-law right now but I was very scared. Then, unexpectedly, Aika pulled me down to watch an adult movie with her, and then we kissed each other's buttocks, kicked each other's tongues, and then sex scenes that seemed like bed collapses happened. I had an affair with my own sister-in-law in the house.
