Apologies if I have shared this before, but furfan’s story reminded me of it

I was playing with a Domme from NYC who was in town visiting. She was doing a variety of CBT on me when she pulled out these rather innocuous looking magnets. She put them on me and the pain just kept intensifying until I was in great discomfort. I then felt this incredibly sharp pain and I just started shrieking “RED, RED, RED”. She gave me a rather quizzical look and said “that was me taking them off”. I said “well carry on then”. We laughed rather hard over it.
