She's his forever

As the cum entered the ****'s body, something else left it. Her ego, her sense of self, was gone. She wasn't a person anymore. She was a foot **** for the Master. She stared up at him, adoringly. "Tell me what you are," came the voice of a god.
"A ****," she said. "For you."
"That's right," he said. "Now come with me. You have a new life to start."
He gestured, and she followed him, staying on all fours. For she was a lowly **** and he was the mighty and perfect Master.
