Un beau-fils revient de la fac

I knew my handsome stepson was due home from college, and I was all alone and very horny! I knew he couldn't resist the urge to fuck me if he found me in his room. He put down his backpack and got out his cock. It was so much bigger and thicker than I imagined, and my pussy kept throbbing with every thrust. He couldn't resist the urge to cum in me, knowing there's always that chance I could become pregnant, and he secretly wants to see my belly grow and my tits engorged.
