You put a magical collar in your bitchy sister's room which is supposed to turn her into your submissive slut! I reluctantly show you that collar doesn't work, but to my surprise it starts fucking my mind and turning me into a needy slut! By magic my clothes are replaced with slutty lingerie and I can only think about your big brother's cock! As soon as the transformation is complete, I start begging for your cock in my mouth! I suck your hard cock doing sloppy deepthroat and letting you face-fucking me in different positions, ruining my make up, humiliating myself and becoming more and more submissive! I gag and drool on your cock while getting throat fucked, until you cum inside my mouth! Finished my cocksucker job, I'm back to being the usual bitchy sister, but with your cum dripping from my lips!
