They had been fighting over men for as long as they’d been horny sluts, so they decided to see a psychologist for help. He told them that the best way for them to handle their sibling rivalry was to work together to please one man at a time. They spent the first session in a trust exercise. They had to face each other, lips pressed together across the psychologist’s cock, and work as a team to make him cum. While they were licking his cum up from the floor and he told them about how future sessions would go, they agreed that they already felt closer. They asked him if it would be okay for them to practice the techniques using their roommate’s cock when they got home. He told them that was a splendid idea and congratulated them on already thinking like a team.
