A classroom of submissive teens, eyes downcast, await their lesson. Their professor, a man of considerable endowment, begins with a demonstration of his "big dick" theory. The girls, eager to please, take turns sucking and fucking, their tight young pussies stretching to accommodate his massive cock. As the class progresses, the air grows thick with the scent of sex and sweat. The professor, pleased with their enthusiasm, rewards them with a bukkake-style finale, painting their faces and bodies with his hot cum. The teens, grinning and covered in jizz, submit to the cleanup as their final assignment.
