I decide to make it up to my sister for being such a "dick" I used to rub her back when we were younger and she always loved it so I talk her into letting me give her a little massage as an apology. It turns out I have turned my sister into a slut for me. She starts getting so turned on...her panties slip off and I start massaging right up against her pussy. She moans a little and grinds on my hand. I slide my cock in her from behind and soon she is losing her mind as I fuck her hard. I can't help but finish cumming all over her pretty slut face. Now she is pissed off all over again, but family forgives.
