My little step-sister has been living with me for a few months and we have an agreement. She fucks me once a month for free rent and board. I don't mind. She is such a cutie and we used to fuck around when we were younger and still living with our parents. She still feels awkward because it's a money transaction now, but we always love feeling good together. She sucks on me and we have a good talk about the reasons why she was kicked out of our parents' place. She has been fucking my step-dad! I can't believe it! She tells me how good his cock and cum tasted but she never let him fuck her ass. She is going to let me fuck her ass soon. I bend her over and fuck her doggystyle and then put her on her back and make her cum until I fill her with a load of cum so deep it barely comes out.
