Summer Vixen and Gia Di Bella, two sultry teens, find themselves in an unexpected and intense 'boxing class' when their instructor, Mary Kalisy, introduces them to a very different kind of physical exercise. The room fills with heavy breathing as the girls eagerly take turns pleasing Mary, their mouths stuffed with her throbbing cock. The air grows thick with the scent of sex as Summer and Gia switch between sucking and fucking, their tight, teen bodies eagerly taking every inch of Mary's massive dick in doggystyle. This boxing class is far from ordinary, but these bored teens aren't complaining.
