Yeah, right in the middle of a booking yesterday afternoon.
I had a client pinned and I was just nibbling ferociously on his ear whilst he was writhing passionately underneath me, when I was overcome with the most awful leg cramp in my thigh. I had to stop and ask the poor client to rub my leg for me. I then had to walk around the bedroom for a bit to stretch it out before I could carry on.
Talk about putting a crimp in the proceedings.
