I surprise you in your room, I just got home from college for winter break! Did step-mom tell you I was coming home? Wait were you.. Jerking off? You were I can see, there's a big bulge. You weren't? Ok then prove it, move the pillow! Ok if you won't do it I'll do it! I jump on the bed and move the pillow and wow there's a huge boner. Its so big I kind of want to see it, I don't care if I'm your step-sister just show me. I pull your cock out and it looks... Really good. You ask to see my tits and I show you, it's only fair. Your cock is turning me on I just start stroking it and before you know it we're fucking. We both cum and then realize you came in me which probably wasn't a good idea..
