My partner and I have been trying out bondage and mild BDSM for a little time now and have collected together a few toys and made up several pieces of equipment for our play. One of the items we have are clamps made from large wooden clothes pins ('pegs' in the UK), which have larger jaws and stronger springs meant for heavy washing items such as blankets. They have been modified by filing teeth across the wooden jaws to give good grip. One set is painted black with green tips to indicate a 2 mm gap between the jaws to restrict the pressure on nipples. The other set has no restriction and painted plain black and are for use on the scrotum.
One day my partner told me that she had thought up a special treat so we muted the telephone and I went to our playroom to get our 'toy box' out while 'Mistress' went of to get ready. When she came into the room, Mistress was dressed in her favourite leather Bustier with breast cut outs to lift and emphasise her already large tits. She also wore a wide leather choker, leather and chain briefs and thigh length leather boots with high heels. She emphasised her dominant position with a leather riding crop.
On being instructed to strip I quickly shed what little clothes I had on and stood waiting mistresses command. She put cuffs on my wrists and clipped them together behind my back. Another set of cuffs were fitted around my ankles and connected to a spreader bar. A leather strap was now fitted around the root of my cock and scrotum while two more straps connected to the first were clipped round to separate my balls nice and taught for mistresses pleasure (and mine but I wouldn't admit it!).
Mistress now picked up the nipple clamps and clipped them on to my left nipple, I could tell straight away that she had the wrong ones and had used the full strength ones. "Mistress" I started to protest only to be quickly silenced by a sharp blow from the riding crop on my right buttock which instantly took my mind off the nipple pain. "Silence" commanded mistress and placed the second clamp on my right nipple which reminded me again of the pain in the other one, "I thought we would have a change of nipple clamps today, after all, I told you we were having a special treat, and this is only the beginning!".
She then placed a small coffee table about 2 foot in front of me and placed our weights on it, two of each 2 oz, 3 oz and 5 oz. I was puzzled by the inclusion of the 5 oz weights as we only use the 2's and 3's on nipples. I started to query the extra weights only to be commanded to silence again and a stinging blow from the riding crop on my left buttock which no doubt left matching marks on the two cheeks.
Mistress now unclipped my hands and told me to pick up one of the 2 oz weights with my left hand and return both hands behind my back afterwards. I did as commanded and she hung the weight on my right nipple clip, just as I had been getting used to the pain in the nipples, this increased the intensity. "Good" she said, "now give me the other 2 oz weight with your right hand".
Again I did as commanded and found that as I reached forwards and down, the weight on my nipple swung forward pulling the nipple straight out 90 degrees to my body, temporarily increasing the intensity of the pain as it did so. She hung this weight on my left nipple clip balancing up the two pain areas.
