Meet Boubacar, the handsome metro conductor in Denver, hiding a naughty secret from his RTD colleagues. When the train's empty, he whips out his phone, scrolling through gay porn, his cock hardening in his uniform. He strokes himself, panting, imagining the passengers' cocks in his hands, their mouths on him. The train's intercom crackles, breaking his trance, but his hunger's far from satisfied.
