I was supposed to be assigned to a local sales office due to a personnel change. Since it was a sudden matter, I was asked to temporarily live in a relative's house near where I was assigned, and there I reunited with my cousin Reo, who I often played with when I was little, for the first time in a long time. Reo, who had divorced her and returned to her parents' house, had become an adult woman with an attractive plump body. That night, Reo came to me who was unable to sleep at night ... From this day on, I was made a tool for her sexual desire processing, which revealed an amazing propensity!
