Step Sis Caught with Hand in Panties - I Gave Her the Real Thing

Walked in and caught step sis on the couch, hand buried in her panties, fingers moving fast. She freezes, blushing hard. I lock the door, drop my shorts and whisper “need something better?” She nods, spreads her legs wide, I slide raw inside her soaked pussy while she moans “yes, this is what I wanted.” Couch creaks as I pound deep until she cums shaking around me, then I fill her completely, both laughing breathlessly.
