Fucking the exhaust pipe of a Renault Scenic

In this video i put my cock in a very different exhaust pipe, it was a very tight fit and the exhaust was very shaky. first, my wife revved for me, sometimes very hard, pushing my cock out of the exhaust pipe and spitting sooty condensation over my balls. afterwards she gave me a hand job, grabbing my dick with a firm grip. when i blew my load it was pushed out by the exhaust fumes and ran all over her hand. both of us enjoyed that.
