Old and young couple enjoy family sex in fantasy

In this steamy fantasy, we see a young and old couple indulging in some family sex. The young man, who looks like a college student, is with his stepmom, who has big tits and a MILF-like appearance. They're joined by the stepmom's daughter, who is not her biological daughter, but rather a stepdaughter. The three of them engage in some intense family strokes, with the stepmom taking the lead. The stepmom's son is seen watching the action, but he's not a part of the sex. The stepmother's stepson is not her real son, but rather her stepson. The stepson is with his real mother, who is also not his biological mother. The fantasy is set in a family therapy session, where the stepmother and her stepson are trying to work out their issues. The stepfather is absent from the scene, but he is present in their fantasy.
