A disturbed teacher, Alexis Fawx, keeps her stepdaughter, Mackenzie Moss, and her mom after class for detention. With a twisted grin, she commands them to pleasure each other. The teen and her mom resist, pleading with the teacher, but Fawx is adamant. She forces their heads together, pushing their faces into each other's laps. Reluctantly, they begin to lick, their tongues tentatively exploring unfamiliar territory. The room fills with the sounds of wet, sloppy licking and the girls' uncomfortable moans.
