18ga Needles in a Penis Pump.

I've been planning to drive a couple of spinal needles down the shaft of my penis but needed my penis to stay hard to cooperate. A penis pump cylinder forces an erection and that solved one problem. The second was i needed strong needles that wouldn't bend, 25ga was too flimsy but 18ga held up but caused my glans and penis to roll up causing the needles not to go straight. I added a 4mm sound that would slide down my urethra as my penis was dragged to the needles ensuring my penis stayed nice and straight. As you can see it was a success!
