H04104 Classmate Who Loves Sex Episode 4

During lunch break, Nitta helps Natsutsuki masturbate, but he has never climaxed and ends up finishing alone as the break ends. Natsutsuki later starts touching him under the desk and lifts her skirt, and they continue in class without being noticed, though she doesn't come again. Eventually she grabs his hand and drags him out of the classroom.
