POV - My Stepsis want to be help

My little stepsister is such a brat! Ever since our parents got together she's been the most obnoxious little brat, always getting everything she wants. Well, not everything it seems… she's been pestering our parents for tickets to go to that concert but they're not giving in. So, I did what any big stepbrother would do in that situation: I got two tickets and got her working for them. She'll do anything for these, so it's only about pushing my luck. She had no problem riding a toy on top of my leg, or putting on a collar and sucking my dick… so something tells me she won't mind me stretching her tight little pussy with my fat cock. Only one way to find out!
