My ex gf ( of 5 years) we were in late 20s ) and I started exploring the lifestyle by being mostly limited to hand play but still very erotic and very intense. We would meet a very hung guy at a restaurant and we would all eat together. I would watch them flirt with their eyes and get to know each other more. Eventually he would lead her outside to his truck while I was paying the bill. Then I would go back to my car and watch the silhouettes of him being stroked by her. The windows would fog up. She would have me on a call and I could listen. As she stroked him and he fingered her. He would send me a few pics also. This went on with 3 different guys and about 7 different occasions total.

Extremely hot and I can’t get it out of my mind :)
