Stepsisters who can't stop fighting? As a therapist, I've seen way worse. Sure, one of them recorded the other having sex, but that's only because she was jealous of how she had been ignored ever since her stepsister got a boyfriend. Or could that jealousy be because of how often she gets to fuck? My job is to get to the bottom of this and help them get along, and there's only one way to do it. I'm going to teach them how to share by giving them something they won't be able to resist: my big dick. They won't be able to fight if they keep taking turns having it inside their beautiful, soft mouths, and after it has been inside both of their pussies, they'll feel so good that any hard feelings will go away. There's nothing an intense orgasm can't fix, and my cock is hard and ready to serve them. We better make their hour of therapy worth it.
