Suspicion Is Sometimes Very Bad

OK, a month ago I started noticing small things around the house that had me convinced my wife was cheating on me. I would come home and our bed wasn't made quite right. Doing laundry one day I found a couple of towels with what I thought was dried cum on them. And a couple of stains appeared on the couch and I know they are cum stains.
So I got a couple of those "hide in plain site" spy cams. Put one in the living room, one in the bedroom. Left them taking video for a week. Thought I had the bitch but boy did I get a surprise.
It appears our 17 year old high school daughter has a sex life porn stars would envy. Damn better than mine! In a week I had video of her having sex with two teenage boys that looked about her age. And one man I estimate to be in his early 20's. She definitely isn't shy or lacking any knowledge of what she is doing.
Now I'm stuck. Can't tell wife and NO WAY I can tell our daughter I taped her having sex.
