My parents remarried and my little sister is a super busty slut who goes to a slutty girls' school! She walks around in defenseless clothes even at home, so her tits and panties are visible! My huge dick reacts to my sister's outfit and gets fully erect! Of course, there's no way I can hide it, and my sister finds me, but she's so turned on by the huge dick she's never seen before that she starts devouring my dick! It feels so good that my little sister goes crazy and shakes her hips and fucks me like crazy! I fuck her everywhere and she milks my dick until it's no longer erect!
