A stepmom, Lexi Luna, and her stepson, Tyler Cruise, have a free-use arrangement, which they flaunt by shamelessly having sex right in front of Tyler's tutor, Laney Grey. But this isn't the first time the duo's pulled such a stunt and Laney is DETERMINED to still teach Tyler the best she can. As the daring duo have energetic sex right in front of her, Laney continues quizzing and platonically interacting with Tyler throughout, showing that NOTHING will faze her.
