I am thinking Scott is the one who liks Lyydia clean the most often, so hungry for a taste of Peter’s cum and Lydia’s juices. when he’s especially good, Peter lets him have at Lydia right after he’s fucked her so Scott can bury his face in her wrecked pussy and lap it all up. She’s so sensitive she’s crying with every tiny orgasm his tongue punches out of her, her body trembling and jiggling so beautifully all the while Peter praises them both for being so good for him. (.. damn, I ship it now)
