For me I was mortified when I was in a scene with new dom who was a friend of the lady I regularly scened with and she had loaded up my nipples with clips and then hung larger and larger weights on them (oh bliss) she had turned away to get another weight and as she turned back I felt one of the clamps start to slip off and before I could warn her it landed on her right toe - unfortunately she was wearing strappy high heeled sandals and her toes were exposed! It was a very heavy weight - and she ended up hoping round the dungeon rubbing her foot - I was so embarrassed for two reasons, I had not warned her and of course for her as it was the first time she had met me and she didn't want me to think she was a clumsy practitioner! When I told my regular lady she couldn't stop laughing! Ian.
