This is absolutely true, and not what you're thinking...
I promise this is true and not what you're going to think it is after reading the first couple of sentences.
I'm a widower raising two daughters - one in Middle School and one in High School - all alone.
I haven't had any involvement with any females since my wife died a few years ago.
We live in a two-story house with a pool.
I let the girls have their friends over (only girls, no boys, because I'm protective like that) to swim in the pool anytime they want.
My bedroom is upstairs and overlooks the pool.
I can see whoever is in the pool, but they can't see me.
A couple of years ago, I started watching my daughters' friends in the pool, and masturbating while I watched them.
Not to my own daughters, of course - just to their friends.
I would never, ever touch an underage girl, nor would I get involved with someone that was friends with my daughters, even if they were of legal age.
I'm just so lonely and sexually frustrated!
Well, that's it.
