Because Eitaro's parents wanted him to stay away from the bustling and noisy city life, they advised him to spend some time at his uncle's house in the countryside this summer. This rural area is surrounded by mountain ranges and vast fields. It takes as long as two hours to get to the convenience store, the phone signal is unstable making it impossible to watch movies, and the nearest neighbor's house is a half-hour walk away. The people here are mostly elderly so he can't chat with anyone. It's been two days and he has nothing to do. Just when he was about to die of boredom, he met Ichika, the wife of the neighbor next door. She is really beautiful... Wait! Her breasts are peeking out from behind her thin top with no underwear!!! That night, Eitaro's uncle asked him to bring some food to the neighbors as a gift, and when he got to the door, Eitaro caught Ichika and her husband making love. Ichika also noticed him, but instead of stopping, she intentionally became more lewd to excite Eitaro! The next morning, Ichika invited Eitaro to her house to play, and she began to use the fact that he had peeped on her the night before to seduce him. How could a boy as inexperienced as Eitaro possibly refuse the invitation of such a beautiful, lewd girl!!! From that point on, they secretly made love to each other, regardless of where or when, even when Ichika's husband and Eitaro's uncle were nearby...
