Casting for a modeling agency of an 18-year-old stepsister did not end as she expected

The half-sister asked her brother for help. She was going to a modeling agency and she asked to shoot a test video for her. The brother made a good video, but everyone understands that all the models fuck. So she took off her clothes and started posing for her stepbrother's camera. His could not stay in his pants for long, so he was in her holes with lightning speed!
