Fucking stepbrother for a blog

My 18 y.o. step-sister is a real mega-bitch who wants to fuck me for her blog just to prove her High School rival she deepthroats and rides dick best. How can I say NO to such a beautiful pussy? So wet and warm, so welcoming to feel my meatpipe deep inside… oh, stepsis! She really rides meatpipe like a goddess and even lets me spunk all over her pussy dipping her fingers in my spunk to taste it and letting me fuck her more after I came… with no rubber!
