JUFE-210 Oka Erina beautifully takes care of the perverted old man.

During the summer vacation, Erina, a college student, returned to her parents' home. Erina, who was drenched in sweat due to the intense heat, knew that the bathtub at home was not working, so she went to borrow the bathtub at her grandfather's house on her mother's suggestion. Her grandfather, who was uncomfortable with Erina's sexually mature appearance after such a long absence, could not suppress the strong desire that arose for the first time in decades and attacked Erina in the heat of the moment. And he exploited Erina's vulnerability, saying, 'In a rural area like this, if rumors spread, mothers won't be able to go outside.'
