Caught In The Act

The other morning I was laying in bed, had the day off from work and the mood hit me. Started pulling one out while watching a little porn. I was a couple minutes in, dick hard, shorts down, phone in one hand, my cock in the other; I look up to see my step daughter come out of her room and was looking directly at me! I froze and I could see her squinting (she didn't have her glasses on) so I just waved, and she waved back then carried on into the kitchen.
I totally forgot they were out of school! I don't think she realizes what she saw, but for some reason it really turns me on knowing that she caught me! She hasn't said anything if she does know.
