This happened just two days ago...
I've been a long time reader of this site and thought it was about time I contributed a story. This occurred just two days ago.
I was at home when my wife stated she was going to watch Big Brother on television in our en-suite bedroom. Personally, I can't stand the show, so I thought it was a good excuse to go out for a jog. As I was walking out the door I noticed that my mother-in-law (we're currently staying with the in-laws) was watching the same show downstairs.
I called out to Pam that her daughter was watching the same rubbish in our room and she should just join her in there. I left for a half an hour jog and thought nothing more of it.
When I returned I was thoroughly exhausted and sweating up a storm. I walked into the bedroom and my wife and Pam were still watching Big Brother. I announced I was going for a shower and my mind immediately started wondering!
We have an open en-suite bathroom which is separated from the main part of the bedroom by a wall that is around six feet long. You can walk into the bathroom from either end. I was having my shower and noticed I could see my wife and Pam in the reflection from the window. It wasn't clear, but it was enough to turn me on and I noticed my cock was stiffening and I gave it a few tugs.
Pam is 52 years old, 5'3' and a nice build. Brown hair and eyes and nice 32C boobs. She is definitely fuckable.
The show finished and Pam got up from the bed and walked to the bedroom door. She looked directly at me and then down to my hard seven inch uncut cock. She got a great glimpse of my fuck tool, lingering longer than she needed to, before then raising her hand as if to say 'I'm not looking'. It was too late, I caught her out. Both Pam and my wife left the room.
The moment was too much for me! My mother in law had just been caught staring at my cock! Sprung! No questions asked! I began masturbating furiously and came with incredible force. I'm hoping to make this a regular thing, and I'll keep you all informed!
