Jealous StepSister

You finally told your step-sister about your new girlfriend and things didn't go well, maybe you should have told her sooner than a few hours before your girlfriend came over for dinner. Your step-sister has always been the jealous type, and spends all of dinner either interrogating your girlfriend or trying to seduce you behind your girlfriend's back! You decide the next day to ask your step-sister to go shopping with you to help you pick out a new shirt for date night, but things take an inappropriate turn when she sucks you off in the dressing room and swallows your cum. You confront her later, telling her that it can't happen again, that this time things are different. You show off your outfit before you leave, and end up getting tied up by your step sister, who grabs your phone and cancels your date with your girlfriend and ends up having her way with you, reminding you just how good her pussy feels. It's so hard to resist so you give in and pump her full of cum! You finally reschedule your date with your girlfriend, not giving your step-sister any notice to pull another stunt to keep you home and bring your girlfriend home to stay the night, but that doesn't stop your greedy step-sister from sneaking into the room and sucking and fucking you right next to your resting girlfriend! Lets just hope she doesn't wake up and find out how much you can't resist your step-sisters pussy!
