Stepbrother was working on a science experiment to take advantage of his mom and stepsister. He started by putting barcodes on them, which he would scan with an app he created in order to have the girls do his bidding. Both Anastasia Knight and Tucker Stevens both knew that he had a wild imagination, so they would play along for whatever he thought was going to happen even though it definitely would not work. Turns out stepbro was not just a mad scientist, but also a pervert! He utilized the app to make his stepmom and stepsis suck and fuck him until he came all over them. The app obviously did not really work and Tucker and Anastasia were just trying to be good family members, but still the fact that was the goal of his experiment was super sick.
