Your step-niece is glad her threats have paid off and that you've stopped avoiding her. She expects to be spoiled and serviced, after all. She knows you're not your usual self and demands you fess up to what's bothering you. Turns out you're flat broke. And that means it's time to put an end to this affair. With such a guilty conscience, you want to tell the fam what's gone on. It was originally Ellie's threat to keep you paying her. You're her old pervy step-uncle, and it'll look pretty bad for you both! It's possible you could be disowned. Ellie pretends to give her blessing and makes a juice toast to new beginnings. Within seconds, you feel odd, unable to keep your eyes open. What has she done?! You awaken nude with your cock out and hard, and your step-niece showing off her hairy cunt. She wants one more fuck before this ends! She gets on her knees and starts sucking you off for the final time. For such a frail man, you do have one giant cock! She never noticed how skinny you were, since you were always mostly dressed for quickies in the past. After some amazing oral, she hops on top and rides your long, fat dick with her bare titties bouncing over you. No climax until she has hers, now!! She reveals in the heat of the moment that she has a fetish for wrapping her hands around necks, and yours is looking mighty good about now. She indulges... and you're too weak to resist! Her thumbs hovering over your hyoid bone... she could easily break it. It's too late for a vow of silence! The secret will end with you. You'll be her victim. But she has a parting gift for you, a final orgasm! You stare into her wide-eyed and puckering face as you receive it... This is the end of everything for you, step-uncle!
