I owed my stepsis an orgasm

My stepsister has a killer body, doesn't shave her pussy and big cocks and loves the taste of sperm. How do I know that? Cuz when she caught me spying on her touching herself with a camera she said I interrupted her masturbation and owed her an orgasm. I was so shocked and so horny at the same time I just couldn't say NO to fucking her right there. That was the best pussy I ever had and she made me cum right in her moth too. What a filthy whore!
