Caught by Our Son

A few years ago our oldest had gone off to college. While cleaning his room my wife stumbled across his porn stash. He had some magazines and a couple of DVDs and he had some pictures I had taken of my wife. I went to my stash and my copies were still there. He must have scanned them. She was stunned. That night when we went to bed I was horny from the discovery. We started having sex and soon I brought up the pictures and what he was doing with them. My wife's pussy was getting wetter the more we talked. I finally exploded in her cunt as we laid there talking I asked if she was turned on by the fact her son masturbated using her picture. She started rubbing her pussy with her fingers and told me it did. The next weekend he came home from college I had a plan. I wanted to see if my wife would let my son watch a live show. That night instead of closing the door of our bedroom I left it cracked open. I turned on a strategic light, it would keep the doorway in shadows but light the bed up. Before he had come in that day I had printed a new picture of his mother looking at the camera and spreading her cunt. I put it in among his stash. I told him we were going to bed and that we would see him later. I started on my wife talking about what if he caught us having sex. My wife started getting wetter and wetter. Finally she started moaning. I got behind her and started fucking her doggie style with her facing the door. I told her she needed to be louder if she wanted her audience and she did not disappoint. WIthin 30 seconds the door moved and I thought I saw a shadow. I leaned over her and said he is here. She moaned and her pussy spasmed on my cock. I pulled out and had her turn around and bend over and suck my cock while fingering her own cunt. I was trying not to cum while trying to see if he was masturbating. I was wondering if he would try to get closer if the lights went out. I turned her this way just in hopes he would try to get his cock in her pussy. That thought was too hot I came in my wife's mouth. I whispered for her to stand up and turn around and play with her big tits. We heard a moan and then foot steps. In our door way was a big glob of cum. About 20 minutes later my wife was ready to go again.
