Walking around the San Diego convention center to enjoy the sunset, I noticed movement down near the loading docks. A cute couple was messing around and I caught them on film! After a few minutes, I decided to risk a closer look. When I got pretty close, I could see her shoving his cock in her mouth. I began to get hard, wishing it could be my cock going down her throat. When I finally got the nerve, I asked them if I could join.
