Secretly touching my stepmom while she talks to my father in law - taboo fantasy

The scene opens with a close-up of a beautiful woman's ass as she sits on the couch, talking to her son's father. The camera pans out to reveal that she is his stepmother, and the tension is palpable. The mother is clearly uncomfortable, but the father-in-law is oblivious to her discomfort. Suddenly, the mother's hand creeps up to touch the father- in-law's crotch. He is caught off guard but doesn't resist. The mother continues to touch him, her body glowing with pleasure. The father-in law is clearly turned on, but he can't resist the allure of his stepdaughter's mother. He reaches down to touch her pussy, and she moans with pleasure. They continue to touch each other, their bodies entwined in a taboo fantasy. The mother's big ass is on full display, and the father-law can't help but cum on it. She gives him a blowjob, and they both end up satisfied.
