A female teacher, filled with anger towards a male student who constantly disrupts her class, devises a cruel punishment for him. Once the period ends and the other students have rushed out, she keeps him behind and forces him to the floor. She then sits on his face, immobilizing him as he struggles in vain. With the boy pinned down, she removes her panties and lowers her pussy towards his mouth. As he begins to comply, she starts to urinate, flooding his mouth and leaving him no choice but to swallow every drop.
