My ass clenches around the machine's thick, unyielding cock as it mercilessly pounds into me, my body a helpless vessel for its mechanical lust. The sensation is intense, almost painful, as it stretches me wide, its steady rhythm driving me closer to the edge. I'm a slave to its relentless motion, my body a canvas for the machine's brutal art, as it fucks me raw, my cries of pleasure echoing around the empty room.
