Well this happened..oooh exactly ten years ago..but at the time I couldn't 'discuss' it with my girlfriends at the time because most of them didn't experience 'that kind of sex'..and would have been mortified..but they were all secretly certain that this man I was seeing was beating me up black and blue.. because I had a lump the size of a golfball on my forehead..
Anyway I was seeing this 'hot guy' (well to me at the time) and one night we were hot and heavy in the bedroom..as one would be (hopefully)..and we are switching all types of positions after the foreplay..so it was (yessssssss I know I know but when your 'young') missionary..then me on the side and him behind..and then me on my stomach, him lying on top..and while we were on the same them we move onto doggy style..
by this time we are 'volcanic'..
so there I am on all fours..he is primed and ready, actually I don't think we paused, and yes the following is the reason why the lights should not be 'off'..

In one clean sweep.. he does his 'thang'..and I am 'what the fuck was that?????????????????'..and I move like Flash Gordon FORWARD.. meaning my head meets the bedhead.. I see stars..he is motionless.. I am having a split second thought of 'Do I deck the bastard or don't I?'.. simply because he was looking at me with the Bart Simpson 'I didn't do it' look..but after that we didn't do anything.. I don't think we knew what to say..

but yeah..
that was my first introduction to Backdoor..by mistake mind you..and at the time most of my gfs were virgins..so it wasn't like I could say 'well he didn't hit me, this golfball is because he accidently knocked on my backdoor'

looking back though..
remembering that moment I do laugh to myself..

It's not a funny story to tell the grand kiddies one day..but
it's funny enough to tell to 'seasoned' adults.
