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.
