A massive dildo-filled machine is set up for Anal fucking. It's equipped with different-sized dildos, each designed to stretch and fill up every inch of the tight asshole. The machine starts slowly, with the smallest dildo gently penetrating the entrance. But as it progresses, the dildos get bigger and bigger, filling the subject up completely. The machine relentlessly hammers away, causing unbearable pain and pleasure. Sweat and tears mix on the subject's face as their asshole is ravaged by the massive dildos. The machine doesn't stop until it's finally released its load, leaving the subject completely spent and satisfied.
