I would like to do the car scene. I would drive and we would pick up her lover. They would sit in the back and get comfortable. After making out, she would suck him and eventually lift her skirt and sit on his cock. She would see me watching her in the mirror and give me a big smile as she ground her pussy on his cock. Then you hear that groan and know that he is pumping his sperm into her inviting pussy.I really do think about all the sexual acts she committed on him and him making her cum hard.
I am currently into the fantasy of another man stripping her and going down on her while I watched. Then watching her ride him to several orgasms. Particularly in a semi public area like in the car.
