Step-Daddy, my step-sister makes the cutest face when she's cumming. Her lips pucker up and then she gasps, her mouth open, eyes screwed shut. It's so fucking hot! Step-Daddy, I'm going to make my step-sister cum a whole bunch today while you're away. I'm going to pin her to the bed and make her cum until she can't move any more, until she's just exhausted. I'm going to use my tongue and my fingers, that little trick you taught me... Step-Daddy, would you like to watch? Listen to me tall you all about it...
