Jeff had to admit that the collie he pictured himself becoming was female. He wasn't sure why, but the idea attracted him. "Sure" he said with an affected casualness. "Let me try being a girl dog."
Sally stated, with a slight note of command in her voice. "The term is 'bitch.' Do you want to be a collie bitch?"
Jeff lowered his head. "Yes."
"Yes, what?"
"Yes, I want you to use the Chronivac to make me into a collie bitch. Please."
Sally smiled. "Then be a good girl and take off your clothes."
As Jeff did so, he felt itching all over his body as his coat was coming in.
