At school, they are teacher and student, but in reality, they are girlfriend and boyfriend. A secret relationship that can't be told to friends, parents, or anyone else. In the morning, she begs him to ride her dildo in the empty staff room, and during lunch break, she has sex with him in a toilet stall, feeling the thrill of creampie sex. After school, they have sex again, hiding from others. But that's not enough, and they even have a dangerous extracurricular class at home, where they'll be fired if they're found out... The teacher and student's lovey-dovey sex never stops.
