Home made amusement

Yesterday I took our picture calendar off the wall to look at the pictures.  I started putting it back but carelessly the picture side was facing the wall.
At this my wife began to laugh.  Nothing amuses her more than watching me make silly mistakes, hearing about silly mistakes I have made, like filling my basket at the supermarket and reaching the cashier's desk finding I have no money with me.  This  kind of thing sends her into fits of hysterical laughter.  She is waiting, and hoping, for the time when I start off to walk to the town having forgotten to put on my pants.
Anyway when I realised what I was doing with the calendar I started laughing too.  I decided to give my wife a good hard smack or two.  It's a thing I do sometimes, especially at moments like this.  She was wearing very short, tightly fitting, thin shorts clearly showing every curve and valley, so a hard smack would land well and feel good.  The first one didn't land right so I pulled her towards me, both of us convulsed with laughter, and gave her two more as hard as I could.  Through the laughter, clinging perversely to me and getting the words out with difficulty, she always tries to say that I am the one who should get spanked, but I always reply that when I make a mistake, she must be the one to get spanked. That makes us both laugh even more.  I have a sore hand, she has a sore arse.  That's married life!
