Few years back me m38 and the mrs f35 and family had to stay with the wife's brothers and his family for a month as work on our home was bein done, luckily they had a really big house and it wasn't an issue, also once we moved in they left on holiday for a week.

So obviously ever night when the lil ones was alsoee me and the mrs would find a room and get down to some bad mom n dad action.

One particular night we did it in the kitchen ,you no the type with a island in the middle.

I'll be honest we put on a great show I had mrs bent over that island as I ate her pussy and ass from the back while stretching her ass out.

Soon I was laying on the table as the mrs lowered her ass on my cock. Ended up finishing all over her chest. We clean up and make our way too shower n bed.

Now fast forward atleast 6 months Both my mrs and sil are away together on friends hen

During the week with the drinks following the sil let's it slip to the mrs about the house having internal cctv !!! And have had for over 2 yrs .....

She let it slip she's seen us that week and that my mrs brother hadn't had access to the cctv system so hadn't seen it but that she was also very shocked to see how my mrs was very agile

There convo then goes on to anal and the mrs tells her all about how I introduced it too her when we first meet and how she loves it........now I'd like to think more happened between them both that night they wax away ,either talking or more but the mrs refuses pointblank to tell me anymore of what went on only that they talked and drank till morning

So now my issue is My sis in law has seen us fucking all over her house In there bed On stairs Basement Bath And in her kitchen on her big posh kitchen island she's seen some of our best work !!

Since then there is this throb in my cock every time I see her hoping and wishing I could have a go with her on that kitchen island
