Stepdad makes free use of her anytime he wants

I know I shouldn't do this. All the other times my gorgeous stepdadughter Naomi instigated what happened and I just couldn't resist. She's made it SO clear that I can have her ANY time I want. She's gone to bed before I got home and I should just leave it alone, try to rest, maybe jerk off, but all Can think about is her tight body, beautiful face and the sounds she makes when I fuck her. She's laying there awake with her eyes closed waiting to see what I want to do.
