Sweaty creampie sex at the end of summer, her cousin, who has become a married woman, can't control her rationality because of the defenseless sexiness of her cousin...

It was the summer of my second year of university. I still haven't used to living in the city, so I decided to take advantage of the Obon holidays to go to my aunt's house in the countryside. There, they met their cousin Tsubasa-nee, who was young but had a crush on him, for the first time in over ten years. She had married and became a married woman, but she was as beautiful and attractive as ever. Her voluptuous body...dripping sweat...smell...sexy, I can't contain my perverted heart... The heat continues every day, and the tropical nights continue. In the sweltering heat, they are sweaty and sought forbidden creampie sex.
