Kat giggles as she lowers her shapely rear down onto her younger bro's face, grinding her lacy panties against his eager nose. "Mmm, so you like sniffing my used panties, huh you little pervert?" she purrs, arching her back sensually. "Well why don't you have the real thing then, huh? Is it my sweaty balls, my juicy ass, or my throbbing little cock that you love sniffing so much when you jerk your pathetic little dick?" She lets out a husky moan, shamelessly rubbing herself all over his face.
