One of the things we do to add excitement to life.
At some point today my wife will disappear and when I have realised this it will mean that the action has started.
I will find her laying on our bed or in our bed clothed or unclothed depending on what she decides. With no words spoken I will go into our bedroom, go and sit behind a screen we have there and through the gap where the hinges are watch my wife.
This will be the start of what you on your side of the pond call a J/O session and what we call a wanking session. She on her part may decide just to finger herself discretely under the sheets or if she has a mind to she will lie exposed using a range of vibrators, dildos and other objects to pleasure herself. In her mind she may be doing anything with anybody but always knowing she is being secretly spied on.
Me in my turn will be exciting myself by playing with myself watching her pleasure herself and wondering which of the pricks she has known she is thinking about.
So when you are all reading this we might both be wanking off in secret. It makes you wonder just how many people are doing it on a quiet afternoon in your street whilst the neighbours are doing the housework. It brings a new meaning to D.I.Y.
