BOOM!! A roar that is not suitable for an adult video echoes through the gymnasium. And it's no wonder. Today's main character, Kokomi Seto, is a hardcore athlete who was the runner-up in the Inter-High School Championships in handball during her high school days. When you see her shoot, you can see the level of experience she has. When she takes off her uniform, she shows off her sexy, slim body with abs that she has trained at the national level, and she also shows off her greedy, aggressive, and erotic side, which is befitting of a top athlete in the making. Kokomi loves handball and sex, and is making her AV debut, so Kokomi must love playing with balls.
