After playing in the pool until they got dark tans, the three friends started secretly discussing the shape of the other girls' genitals in the classroom after school. "Hey, my genitals have been itching lately, and when I touch them, I feel weird..." While they were showing each other their genitals, they were found by a boy and in exchange for keeping it a secret from the teacher, the six of them decided to have an orgy and cum inside each other.
