Cheating on Wife by Giving 19 Year Old Babysitter a Creampie

When we hired our babysitter Ali, my wife was a little nervous because she was only 19 years old and really cute. I swore to her I'd never cheat on her, but when Ali surprised me by coming into my bedroom wearing sexy red lingerie I couldn't resist. I got so turned on by the thought of fucking someone old enough to be my stepdaughter I creampied her with out thinking. I'm hoping her pregnancy test comes back negative because my wife can never know what happened!
