There is a good reason sprain rhymes with pain

Obviously there is (as there should be) a difference between pain gained by using those muscules which in Singledom have long remained doment, and pain gained by an actual sex sprain.
Hobbling around the office has generated some interest today with reaching for items become a bit of an exploration in pain , 'what have you been doing?' seems to be the red hot question, what can reply be issued without rousing suspision? 'I played a massive round of golf and perfected my backswing.'
Of course, that is ridiculous and would only work if I knew what that actually meant. The truth of the matter is, I have a sexy sex sprain.
Saturday night after being out on the town with GKBee we came home pissed and had a great sex session, during he flipped me over, and pinned my hands behind my back and did a bit of hair pulling.
HOTT HOTT at the time, but apprently not a position ones arm are conditioned to be in with another perons weight on top.
