Yuki-sensei is a slutty teacher who has become addicted to semen. After school, she stops the boys on their way home from club activities and forces them to have sex, issues a no-masturbation order to students who look lively, and milks their thick semen herself. Then, during an exam when all the students are present, she can't hold back and has sex and bukkakes them, milking the semen of the boys all over the school as if it were her own!
