You're such a perv, being so into your step-sister. You know she's such a bitch, but she's just way too hot. So when she's been wandering the house wearing a tiny crop top and pleather shorts that just highlight her ass while you have friends over, you get defensive. Telling her that she's dressed like a whore, but she can tell that you like. A smile lights up her face as she mocks you for being into her. She laughs at you, taunting and teasing you with her body. And then an even more sadistic idea crosses her mind. Of course, she's always been a bully to you... She tells you she's going to shrink you down and play with you like a toy. She start shrinking you, foot by foot, teasing you even more with her hairy pussy and tight ass. She tells you she'll hide you in her tits, or maybe in her ass. Mm, the idea turns her on so much that as you shrink even further and starts grinding her pussy against you, still insulting you. You don't think she'll ever turn you back to normal.
