Mummy is out shopping and stepdaddy gives me a big load

I made myself comfortable on the sofa with my dirty novel and played a little with my wet pussy when my stepdad came in and caught me. I thought he had gone shopping with me but that doesn't matter now as horny as the cock in his trousers is hard ... I just can't help it and want to let him fuck me! Is that reprehensible? But what I really didn't expect was that he wouldn't pull it out in time and inject me with a big load of cum ... I don't take the pill!
