First move on the new Stepmom.

Dad married a big-titted slut.

I might as well enjoy it.

While he was away on business, I snuck up to their bathroom.
The water was running in the sink, but not the shower.

On the hidden camera, I can see that she was about to start it.

Stashing my phone nearby, I opened the door and was 'surprised' to come across her naked in there.

"Oh, sorry," I lied, "Shower is not working in the other bathroom."
"Well, you'll just have to wait your turn," she said, covering up as best she can.

I made sure that she could see my young, fit body before I made my exit.

After I left, I saw her playing with herself in the shower.

The name she called out wasn't Dad's.
