I should have been assigned to a local sales office due to personnel changes. Due to an emergency, I asked to temporarily stay at a relative's house near the place I was assigned, and there I met my cousin Reo, whom I often played with when I was a child, for the first time in a while. Reo divorced and returned to her parents' house and has now become a mature young woman with a plump and attractive body. That night, Reo came to me, who had been having trouble sleeping at night... From this day on, I was turned into a tool to handle her sexual desires, which revealed an amazing tendency!
