Mark Wright's homemade dildo machine is a beast of its own, its mechanical piston a relentless, grunting lover. Mark, a willing participant, lubes up his tight hole and positions himself on the machine. The dildo, a realistic replica of a thick, veined cock, penetrates Mark's ass, stretching him wide. The machine's pace is punishing, a constant, grinding invasion that has Mark gasping and moaning. His own cock is rock hard, pre-cum dripping as he's fucked by the machine, his body tensing and relaxing in rhythm with the piston's relentless drive.
