I was transferred to a local sales office. Since it was a sudden request, I was temporarily staying at a relative's house near my new location, and there I met my cousin Reo, who I used to play with a lot when I was little. Reo had returned to her parents' house after getting divorced, and had become a grown-up woman with an attractive, curvy body. That night, Reo came to me as I was unable to sleep... From that day on, I became her tool for satisfying her sexual desires, revealing her surprising sexual proclivities!
