VEC-459 Mother's best friend Sakurai Yumi

Despite being an examinee, Gaku was at a dead end because he could not concentrate on his studies. She immediately thinks about lewd things and can't go back to studying until she pulls out once. It was a study that was plagued by such worldly desires, but her mother's best friend Yumi came to play there. Manabu, who is completely fascinated by Yumi's seductive adult charm, ignores his studies and indulges himself in comfort, but Yumi comes to see what's going on there.
