What was something inappropriate a member of your family caught you doing?

(This was written 3 yrs. ago but deleted for some reason) Just tonight, a short while ago, I went to the bathroom to relieve myself and discovered I have been seen by my brother in law’s 18 year old granddaughter. They are spending the night and she is sleeping on the couch right next to my chair which I was sitting/going to sleep in, lights out, looking at my laptop computer which is bright enough to keep me from seeing into the dark room behind it. I have earbuds in and don’t hear sound around me with them in as my hearing is very poor to begin with. I had been under a blanket which had made me hot so I had removed all of my clothes I was wearing and just covered my manhood keeping both legs sticking out as I presumed she was asleep. I was looking at some really good photos of a sexy lady who was wearing see through clothes at various public events. I was getting a stiffy, so I reached down and was just slowly rubbing my hard dick as I had pulled it out from under the blanket. I then moved onto some of the really good sex stories found here on Quora and was becoming more deeply interested in the stories continuing my stiffy. (She is now asleep as I hear her snoring, LOL.) She is a little hotty but I would never consider doing anything with her even if invited to. I’m not sure just what she could see or when but I know she got up at some point to go pee because I left the lid down on the toilet when I last used it. Soooo, when I went to use it again, the lid was raised up with the seat down as ladies use the toilet. I am assuming she got to see me with a total erection and stroking it. Tomorrow morning will be interesting to see how she acts. I will post an update if something worth mentioning comes up. (Nothing was ever said)
