At school, they are teacher and student. When they are alone, they are girlfriend and boyfriend. A forbidden school love between teacher and student that must not be known to the school or parents. Early in the morning, they ride a dildo in the empty staff room, and during lunch break, they have a thrilling secret sexual encounter in a toilet stall. And after school, they stay behind in the classroom where the setting sun shines and have creampie sex, and then as a reward for working hard at club activities, she handles his sweaty dick, and then the extracurricular sex education lesson begins at the teacher's house!
