I couldn't be happier to have approached the end of the challenge. After Martin added more weight to the chain of the nipple clamps, I was devastated! My mascara-stained face was proof enough. Trickle of drool hangs down from my gag and my legs tremble from being into a bent position. I couldn't take it any longer, so by the time I hit my 15 minute mark, I was more than ready to be done. Great challenge!!
