Haruma, a young student, was entrusted to a relative in the countryside during the summer vacation because her parents were assigned overseas and were not in Japan. There he reunites with his first love childhood friend Kaworu for the first time in years. Kaworu is now an adult woman. She seduces Haruma with her hot summer sweaty boobs and lustrous gaze. One day she suddenly said, "If she's a virgin, I'll take her away." I don't have any friends, but during the summer vacation in the countryside, I was sweaty with my next H-cup busty sister.
