I was supposed to be assigned to a local sales office due to a personnel change. Because of an emergency, I asked to stay at a relative's house near my assigned place, and there I met my cousin Reo, whom I used to play with when I was young, for the first time in a while. Reo, who had divorced and returned to her parents' house, had now grown into a mature young woman with an attractive, full body. That night, Reo came to me, who had been having trouble sleeping at night... From that day on, I was turned into a tool to handle her sexual desires, which revealed an amazing tendency!
