During class, Mashiro was found by a homeroom teacher who hated to keep an exchange diary, and decided to receive a sermon after school. Mashiro gradually gets nervous and urges to urinate at the sermon of a neat teacher. Pure white that has reached the limit will be leaked. The teacher can not suppress the excitement in that figure, sucks panties covered with pee, licks the pussy, and replies. In addition, Mashiro is confined to the warehouse, and even more ● is added. Too scared, Mashiro leaked again.
