I was assigned to a local sales office due to a personnel change. Since it was a sudden story, I was temporarily allowed to live at a relative's house near the place where I was assigned, and there I met my cousin Reo, who I often played with when I was little, for the first time in a long time. Reo, who returned to her parents' house after a divorce, had become an adult woman with an attractive plump body. That night, Reo came to me who couldn't sleep at night ... From this day on, I was made a tool for her sexual desire processing that revealed her amazing propensity!
