It’s summer and Kohei parents go to the visit their relatives in the mountain. Which include superstar Auntie Kyoko, a sassy Auntie with a pair of ginormous tits. It all compounds, as Kohei is a bit rebellious because he is at “that age”.
That same night. Kohei is helping Auntie to prepare the beds and suddenly Auntie trips down and so does Kohei which lands directly on top of her Auntie tits. He insta-likes it and decides to grab some more, awarding himself an epic boner.
