Summer of my second year of college. I'm still not used to living in the city, so I decided to take advantage of the Obon holiday to go to my aunt's house in the countryside. There, I met my cousin Tsubasa-chan, who I had been in love with since I was a child, for the first time in over 10 years. She was married and had become a housewife, but she was still as beautiful and attractive as ever... Her voluptuous body... dripping sweat... her scent... her sex appeal made me unable to suppress my Kokoro... Day after day of scorching heat, and tropical nights continued. In the sweltering heat, we engaged in forbidden creampie sex, covered in sweat and seeking each other.
