Horny Couple have a 3Some with 18yo Roamer

SCENE opens on a car as it speeds down a desolate road. The sun is blazing. Classical music is blaring. Inside the car, Gloria and her husband, Markus, are driving home after a business meeting. From their attire, you can tell that the couple are successful, but things do not seem particularly harmonious in the car. Markus sits silently, gazing out the window, while Gloria obsessively dissects the potential deal they just negotiated. She turns off the stereo when it clear he isn't listening.
