I have on of those spy cameras and whenever we have a female guest stay over (sister-in-law, wife's friends, daughter's friends changing for the pool, etc.) I secretly video them. Usually, I've caught them undressing but once I captured a video of my wife's old college friend masturbating. When I'm alone or when my wife and daughter are asleep, I play these short videos on the computer and m*********. I've even done this with one on the used panties of these women pressed to my face so I even know what their v*****'s smell like. My wife had no idea I do any of this and would kill me then divorced me if she found out! I have to admit that I enjoy this much more than boring s** with my wife.
