I've been obsessed with the idea of getting pregnant and since I can't find a boyfriend and we've been caught checking each other out, why don't we just fuck and have a babe? Don't worry, no strings attached. I just want a good proper creampie. But, you like fucking girls in the ass. Reluctantly, I comply and allow you to penetrate my tight asshole only if you promise to creampie my pussy and knock me up. Of course, you agree and start fucking my ass as hard as you can. You never knew your sister was such a dirty little whore. Here she is, dirty talking to you, telling you to fuck your stepsister in the butt among many other vulgar things, being a complete and total anal fuckwhore just for you.... man, you've really got a sister....
