I lost a bet with a "friend" from work...
I said I would be able to hit his sales target by the end of the month... he doubted it and said "if you don't hit my sales target you will let me beat you up". I confidently accepted the bet and got screwed.... On the first day of the month I came to him and said "ok, I lost, now let's arrange my beating.". He was surprised, he thought the bet was a joke, but as he hates me at work he agreed in a heartbeat.

Since I lost, I asked if I could choose how I was going to be spanked... and of course I suggested gutpunch. Luckily for me or for bad luck, he agreed. I promised he could spank my abs as much as he wanted... and the spanking lasted 3 parts... this is the first part.
