I don't think this is just a fantasy. I have experienced this type of situation, with several women, often. You just have to be sure you want to experience this.
I personally love this. Whoever the company is (I used to know but forgot) makes very good "slut training" videos & such. Very hot stuff especially that Danica is in them
Danica is not getting "paid to fuck" in this scene. It's like saying "Danica only sucked dick but didn't fuck". Well, that's because she was only getting paid to suck dick. Same here with this scene. Enjoy it for what it is.
