So, I checked online and found my answer, a camera that was disguised as an alarm clock! I found a place that sold them and, of course, I immediately went out and bought one.
I placed it in the bathroom she would be using, I figured really good lighting in there, close up shots, and of course she would have to go in there to shower!
One morning, right after I had the camera set up, she called down asking where we kept the towels, and I knew the moment of truth was coming up!
I made sure everything was set up perfect, and set the recorder going ( yes I was recording this all!) and I almost had a heart attack when the door closed and about five or so minutes later I heard the water running for the shower. I was Positive something would go wrong. That had to be the longest thirty minutes in my entire life waiting for her to finish up!
She came out, and I headed for the recording as fast as my feet would carry me.
So she walks in the bathroom wearing sweats and a t shirt, her nipples poking thru due to the fact that she wasn't wearing a bra, and almost immediately pulled down her sweats and panties. Oh my god! I was suddenly looking at my sweet sister in laws pussy! I could not believe this was actually happening! I was actually shaking with excitement.
But this was only the beginning! Without wasting any time, she removed her t shirt and behold I saw her standing there completely naked! She stood there looking at herself in the mirror for a bit, then turned around to check out her own ass!! Giving me a front row seat to the ass that I have been staring at for many years.
And she stayed with us for over a month!
I went on to record many many such moments, all priceless.
