The couple in Scene 1 is a time bomb waiting to detonate. They're hotter than the fire in the fireplace behind them. No extraneous moves are expended unless some sexual gratification ensues from there. Every ounce of their effort is calculated to bring some erotic sense of satisfaction.
They even manage to throw in some anal stimulation as well. And if Scene 1 is any indication of what you'll see in the remainder of the film, you don't want to miss a moment! Fuck My Hot Pussy - the name says it all! These horny sluts want a stiff rod in their hot box and they get it.
