Tied down to an old fashioned dentist chair, and slowly reclined backwards , my sub is in for it. Terrified of needles, he is about to get some through his cock and balls. I snap on my black nitrile gloves and get to work yanking his balls spread apart with forceps. Then I slowly trace the sharp needles over his cock and balls. Then poke him. He had no idea when I will do it, but I suddenly piercing him. After several needles, I grin and give him a urethral sounding on top of it. Next time, he is getting my entire needle collection.
