Mark Wright, the insatiable bisexual stud, can't resist the allure of his favorite machine. He strips naked, his cock already throbbing with anticipation. Climbing onto the machine, he lubes up, positioning himself so the piston can slide in and out of his hungry ass. He moans, his cock slapping against his abs as the machine picks up speed. He switches between riding it and letting it pound him from behind, his body coated in sweat and cum. When he finally can't take anymore, he strokes himself off, adding his load to the machine's sticky surface, before collapsing, spent and satisfied.
