My stepsister is anything but shy; what a slut in private!

When my dad told me he had a new partner and that she was Hispanic, I never imagined that this woman would come home with a daughter my age, haha. Damn, the girl didn't talk much at first, but damn, in private, she was anything but shy. My dad has brought a young Honduran woman into the house who does things to me that my girlfriend wouldn't do even if she wanted to...
