For a few bucks, a naive straight twink agrees to an 'anal exercise' on the public bus. The gay driver leads him to the back, whipping out his massive cock. The twink, nervous but turned on, tentatively sucks it before bending over to take it raw. The bus passengers watch as the twink's ass is pounded, his moans echoing through the vehicle. The driver pulls out, covering the twink's used hole with his load before paying him and sending him off, his shorts stained with cum and a newfound kink.
