Stepmom gives her son a lesson in Fucking

My stepmom is so fucking hot. She's always teasing me with her huge tits and perfect ass. It never went further than just teasing, until just the other day. I was studying with my girlfriend, when My stepmom calls me in her room. She claimed she needed my help unzipping her dress. Once I helped her with that, she proceeded to force herself on me. Soon after she started sucking me off, best BJ I've ever gotten. A few minutes into the best head of my life, my girlfriend comes in to disrupt the fun. My stepmom used her sweet talking skills to turn my girlfriends frown upside down, and made her join us for some three way fun. I pounded the shit out of both of them while they ate each other out.
