In a straight jacket and spreader bar I have rendered this slave unable to move freely. Once in this compromised position, I put him in a humbler but to the front. I then put clothes pins on his teeny cock all around the head. I use both pain and pleasure by placing a vibrator on his cock shaking the clothespins. I slap the clothes pins almost bringing him to his knees. Just the slight moment of my hand brushing up against the clothes pins sends him into agony.
