In a game of truth or dare, Kitty Cam and Lily Thot challenge one other to descend the stairs while completely naked in front of their respective stepbrothers. Kitty easily completes the challenge, making David horny for Oliver’s stepsister in the process. To make sure the girls aren’t up to any more silly antics, the males decide to check on them, but when they discover them licking each other’s pussies, they switch places and fuck each other’s stepsisters instead!
