No need, I beat ya too it, master dear.
Yes, I saw it at a BDSM meeting where people were displaying their favorite techniques, and the suction play I saw gave me the heebie jeebies. Basically what he did was he had a bunch of small, round conelike glasses with a small hole on the top. He placed about half a dozen on her back and then attached a hose which led to a machine that was basically a small vacuum cleaner. It sucked her skin up into the cup, and I swear, I'm not lying, probably raised it a could two to rwo and a half inches off her body. Unfortunately, a few places where the skin wasn't as thick, the skin broke and caused a good deal of bleeding. The submissive didn't seem to mind but it turned me off ever wanting to try it.
The other things I saw were equally shock worthy, at least to me seeing as I was still very new at the whole thing. I saw scarification, a man blow darts into a woman's butt and back then pick them out with a bullwhip (shudders) as well as a woman who had 6 needles poked stright through each of her nipples (no way). I also say a male submissive and his male dominant. The dominant likes to attach a bowling ball to his submissive's testicles and swing it....and the submissive enjoyed it. Like I said, it was very shocking to me. I had seen that sort of things in pictures online, but when you see it in person it is completely different.
