I'm your step-mommy and you have the day off. We start watching a movie when it gets hot and heavy. I see you playing with your cock but don't say anything. I get in the shower and can't stop thinking about how hot you and the movie were! I get out and notice my panties aren't where I left them. I walk into my bedroom and find you using my panties to stroke your cock! I start playing with myself before you notice I'm there, then I surprise you by stroking your cock for you! You fuck me hard until my pussy is dripping with your cum, sooo much it might even get me pregnant ;)
