You told me you wanted to stop meeting like this... you said it was wrong to fuck your stepsister, but I decided I'm not done with you. It's too late to turn back, and if you try and tell anyone about this, I'll tell them exactly how you took advantage of me the first time. So lay back while I suck your cock, strip out of my clothes, ride you in reverse cowgirl, and let you fuck me nice and hard. And remember.... this is our secret (This is by far the best of the three videos currently in my 'Stepsister Blackmail Sex' series, in my opinion!)
