Am I A Perv?

A month ago I had a feeling my wife was having an affair. Bringing someone home daytime for quickies while I was at work. I ordered a couple of those spy cams to catch her. It wasn't her, it was our 17 yr old daughter! In a weeks worth of video I recorded our daughter having sex with not just her boyfriend, but 3 other boys.
Problem is I haven't erased the video or told my wife. Yesterday I watched some of the recordings and masturbated.
