Your step sister Anna Swix has been hounding after your cock since the first day you met. Until now, you've shown restraint, but you're only human and your balls are starting to get bluer than a BB King solo. Anna knows you though, she knows that you will break. When your parents are out of town she begins teasing you every chance she gets. First its nudity at the breakfast table, then pussy flashing in the car, and finally she gets physical. She's been fucking with you for far too long now, it's time to fuck her back.
