Wanting to get away from the hustle and bustle of city life, Eitaro's parents advised him to stay with his uncle in the countryside for the summer. Surrounded by mountains and vast fields, this rural area was a stark contrast to the city. It took two hours to get to the nearest convenience store, the phone signal was unstable making it impossible to watch movies, and the closest neighbor was a half-hour walk away. The residents were mostly elderly, so Eitaro couldn't chat with anyone. After two days with nothing to do and feeling bored to death, he met Ichika, the wife of the neighbor's uncle. She was truly beautiful... But wait! Her breasts were peeking out from behind the thin, sheer top with no bra!!! That night, Eitaro's uncle asked him to take some game meat to the neighbor's house as a gift. When he arrived at the door, Eitaro caught Ichika and her husband having sex. Ichika also noticed him, but instead of stopping, she deliberately became more provocative to arouse Eitaro! The next morning, Ichika invited Eitaro to her house to hang out, using the incident from last night to seduce him. How could a naive boy like Eitaro refuse the invitation of such a beautiful and seductive woman!!! From then on, they secretly had sex with each other, no matter where, no matter when, even with Ichika's husband and Eitaro's uncle nearby...
