You and your StepSister are PlayFighting and you are losing so you start to tug on her clothes. First her sports bra (which she takes off to fight better) and then her skirts and underwears. You are surprised she wears many of them as she tries to fight you off from removing those. She becomes very embarrassed. You discover that she has a curse where she has to let any guy who sees her pussy fuck her. That is why she hides her pussy so well. So she begs you to fuck her, even though she is disgusted that it is her stepbrother, and tells you off once the sex is over! *pov sex with dildo, implied cumming only
