Left Alone: Male Slave tied to an Anal Fucking Machine to Pound his Prostate until he leaks

Things take a very unexpected turn for this tied-down slave when his mistress decides to give him a particularly unusual punishment. She secures him firmly to a bench, restraining his arms, fastening his body with ropes, and holding his legs apart with a bar. Expecting something like a blowjob from his mistress, he soon realizes that she has something completely different planned for him. She positions a fucking machine behind him, inserts the dildo in his Ass, and secures the entire setup. Once everything is firmly in place, there is no way for him to free himself or stop the machine. She then turns on the Auto Milker Pro 2.0, a device synchronized with his pulse and the machine's operating speed. Its purpose is simple: continuous prostate stimulation until he begins to leak. And then comes the biggest mindfuck of all. His mistress simply walks out of the room, leaving him completely alone, restrained to the machine, with no idea how long it will fuck his Ass or when the penetration will finally end.
