I fuck the Mini Cooper with the dual exhaust pipe again

Again i fucked the dual exhaust pipe of the mini cooper. you already know how good it sound and how strong the pulsating exhaust fumes are pumped on my balls and my dick. this time my wife also gives me a hand job while i fuck her exhaust pipe. the insides of the exhaust pipes are covered with a fair amount of soot from the turbo charged engine, and my dick is quite black after some time. nevertheless, my wife takes matters in her own hand and jerks off my soot covered dick and i blow my load in the steaming tail pipe.
