Me and my whore of a step sister saw the family today. I know she was nervous, cuz after going to dinner with the parents, she thanked me for keeping her secret. I don't know, I kinda want to tell the family that she's selling pussy, but what I really want is to blackmail some sexual favors out of her ass, especially after feeling her up a couple weeks ago. I tried to swindle her out of a blowjob, but she seemed disgusted that her own step brother would want that, so we compromised and she agreed to a hand job. She seemed pissed off and grossed out the whole time, but whatever, she made me cum just like she does with her sugar daddies, so I don't feel bad... - Teen, 18, redhead, big butt, big ass, handjob, POV, blackmail, taboo, brother sister, step sister
