Due to her parents' circumstances, the female student Uta was sent to live in the countryside where her grandmother lives, where there isn't even a convenience store. Her boredom makes her sexual desires boil up, and she starts seducing her mother's childhood friend, the neighbor, the earnest village chief, and the innocent old men with her big breasts. Her firm breasts are sweaty and shiny, and her youthful, firm skin has a magical effect on the middle-aged men, who can't refuse her... Her summer vacation is filled with nothing but sweaty, messy sex with the old men, whose reason has been blown away.
