When Aizawa returns to his rural hometown after a long absence, he discovers that his adult childhood friend Hana has moved into his family home and is living in his old room after her parents’ divorce left her with nowhere else to go. The sweet, reserved girl he once admired has grown into a carefree woman who lives on impulse—and nearly every man in the village is now her fuck buddy. Aizawa can only watch until the sweltering night of the summer festival leaves them alone together in his room. Unable to contain himself, he buries his face in her pussy before the two of them start fucking.
