We told Chrissie that she was going to fuck a much-older man on-camera. She told us that wouldn't be a problem. We told her that she was going to have to suck his dick down to the base and she would probably gag on it. That didn't bother her. We explained that all of this would take place in a pool. That was an issue for her.
We didn't know that Chrissie can't swim. Luckily, her stud in this scene is an old-hand at swim instructions. He held her in the water and taught her a few strokes.
Then she gave him a few strokes.
