I love jacking off. I have been doing it since I can remember and had never been caught, although I came close several times.
This time was different. My wife's best friend was spending the summer with us. After a while it became normal for us to walk around in our pyjamas. This particular night I was sitting on the chair across from them where they sat on the couch while we all watched tv.
My wife was wearing her normal nightgown which covered her pretty much and her girlfriend was wearing a short skimpy nightgown that when she was sitting did little to cover her panties.
I was bored with the tv and was watching her girlfriend combing my wife's hair when I realised I was getting turned on by it. Not wearing any underwear under my pyjamas I reached down and very carefully pulled my erect dick out and started stroking it. With my legs over the arm of the chair I knew it was not possible for her to see me if she glanced over, which made it even more exciting. I just watched her as I stroked my hard dick.
After a few minutes she stopped combing my wife's hair and told her she would be right back, she had to use the restroom. I stopped stroking and just rested my hand on my dick hoping she would not notice. Apparently she did because when I looked up at her she was just smiling as she went down the hall to the bathroom. A few minutes later she came out of the bathroom and looked at me again smiling and then sat down. She grabbed the comb and started combing my wife's hair again, but this time she sat with her legs pointing directly at me.
As I started stroking my still hard dick she slowly spread her legs apart. With the light in the room I could see clearly that she had taken her panties off and I was greeted by a very smooth shaved pussy. I was delighted and not sure if she had done this on purpose or just decided it was too warm to wear her panties. I just kept stroking my dick and knew it wasn't going to be long before I came. I unbuttoned my pyjama pants and spread them so when I came it would be on my stomach. As I was slowly taking in a deep breath getting ready to unload my cum, my wife's friend turned and looked directly at me smiling and spread her legs even further apart. I exploded, cumming all over my stomach and shirt. I just smiled back at her and when my dick got soft I guickly got up and went to the bathroom to clean up.
The next day when my wife was getting dressed her girlfriend came over to me and asked me if I enjoyed the night before. I told her yes. She told me there would be more but it would have to be shared, which of course I had no problem with.
