to Robaust :To be fair, Mrs. Rocket announces several times in teh video that she is urinating. She has always been an honest pronographer and I really respect her for that.
The reason why Mrs. Rocket is laughing and having a good time is because she is truly astounded that she is paid good money for urinating comfortably while a silly man is penetrating her from the hole where she flatulates and another one is excitedly filming all of this. This she clarly finds hilarious and so she is enjoying herself. No shame, no anguish, just level-headed fun and games. I LOVE her attitide a great deal indeed.
