Surprisingly never. But I have been caught. I was masturbating to some porn pics in my office. The office is by the front door, and my office door was open. When I finished my session, I noticed my wife’s assistant had left flowers for her birthday in the foyer. At that time, I was embarrassed. She definitely must have seen me. She had a crush on me, and I did for her, so I guess all was well.
I don't know if this is a relevant topic, but my girlfriend just loves to watch me jerk off. I don't know why, but she gets wildly turned on when I jerk off to old hentai, something like this tamil sex video. It's funny, but it doesn't work with the new hentai. With regular porn all the more so. For about 15-20 minutes she just watches and then pounces like it's the first and last time. After that we always have passionate sex.
