He fills her pussy with semen in a fake casting.

The girl attends a casting to be a model or actress and is offered to do porn. At first she is not very attracted to the idea until the benefits are explained to her. The man offers her a casting to show it to producers and she accepts. He fucks her as he wants, giving her directions and she is very obedient. After fucking her he promises to send the casting and call her when he has news. What the girl does not know is that the agent is false and there is no casting or producers, she was simply fucked by a stranger and filmed.
