Recently, I paid money to a girl to hurt me.
We met at the appointed time. She was probably half my age, and smaller than me, but she carried herself with a confident authority. We had a discussion in which we agreed that this relationship involved invasion of personal space (mine), and power (hers) to inflict physical discomfort. We also agreed a safeword and when I, in an attempt to ease the mood, said I might thump her if she hurt me too much, she replied that I wasn't the first client to make such a threat.
At one stage in the proceedings, she permitted me to hold one of her toys and use it, if I wished, to apply a counter irritant. This, surprisingly, worked but she didn't allow me this release for long.
When we were finished, I felt cleansed and refreshed. I can now see why subs experience a sense of well being after play.
Before I left, I made a next appointment with my Dental Hygienist.
