I had heard of this but though someone just had the ropes too tight. Had an experience recently that made me rethink it.
There was some restraint but only in that I had her in a position she couldn't escape from. I was using a toy that was "G" relevant and included a clit stimulator. She had a couple of light O's and then she held one until she couldn't. It was pretty massive and I was holding on for dear life. Kind of like bull riding; it's not real comfortable riding the bull but its probably safer than getting off.
It took several minutes for her to regain control of her legs. I think this is physically possible due to the way all of the nerves from the belly down come together in a single bundle near the base of the spine. A massive O could overload this bundle and block out other signals - thus numb legs.
Other than heart risks, does anyone know if there are other concerns? Kind of ended our date as she was so exhausted, it was time to let her sleep. But WOW was it a sight to behold!
Your experiences and comments, please.
