Our parents are out of town for the whole weekend. I'm cleaning up my step-sister's room and find her diary lying on her bed. I'm shocked! She's such a whore! She wrote that she wants me to fuck her in the ass with a strap-on like I do my girlfriends. I confront her about it and she has no other option but to let me fuck her tight little asshole. I fuck her in missionary on her bed first. Then, she rides my strap-on like the whore she is. I fuck her doggy style and then she puts my strap=on in her mouth and licks off all the anal juice;)
