Struggling to break free from his restraints, the Milking machine is sucking and stroking up and down on his cock extracting spurts of semen with each suck, he has an intense forced orgasm, ((cum flows from his cock through the tube filling the machine and running down his balls)), he is desperate and in pain, (((he is trembling, his cock is pulsating, flexing his muscles and pulling on his chains but can’t stop cumming)))
