Jay Romero and Della Cate, stepsiblings with a secret, sneak into the family den after everyone's asleep. Della, wearing a tiny nightie, straddles Jay, her warmth evident through his pajama pants. "I want to teach you things, Jay," she whispers, her breath hot on his neck. She guides his hands to her breasts, then lower, teaching him how to pleasure her. Jay's cock throbs, eager to learn. They kiss, tongues tangling, as Della shows him how to finger her, how to make her moan. Jay reciprocates, his touch hesitant yet eager, learning his stepsister's body, their new rules binding them in forbidden delight.
