You and your step-sister-in-law is over at your house and your wife has gone to bed. Can you believe your step-sister-in-law wants to have some harmless secret fun with you while you both have the chance? It's not cheating if you don't touch, but you can look. Watch as she undresses and plays with herself POV while you stoke that cock. Exposing yourselves to eachother while your wife is just in the other room is risky and taboo but you're having way too much fun.
