Your step-sister-in-law feels like she chose the lesser of two stepbrothers and she wants to find out for herself right now. You are alone with Jessica when she makes the offer to show you hers if you show her yours. You are torn about betraying your step-stepbrother, but you cannot resist sexy Jessica. As long as you do not fuck her, there should be no issue. You take your dick out and she immediately knows that your cock is much nicer than her husband's cock. She strips down and asks you to stroke your dick for her. Jessica really wants to reach over and touch you, but even a slut like Jessica has boundaries. She puts her ass up in the air as she asks you to play with the tip of your cock.
