She offered John to touch her cock to make sure

"I'll do it by letting you experience if your fantasy is right or wrong." Dr. Valentine stood up, her hand still gently stroking her big cock. "Now tell me what you see."

"I see you still gently stroking your cock." John replied.

"And how do I look?" The therapist asked. "Do I look like a man posing like a woman? Or like a shemale? Or like a woman?"

"Like a beautiful woman."

"In greater detail."

"Like a young beautiful woman with long blond hair, wearing a black suit with a big cleavage and big breasts, a short black skirt, black stockings and black high heels. All in all like a very sexy psychologist."

"So I look like a real woman and not like some man turned into a woman with a cock?" Dr. Valentine asked.

"Yes." John confirmed. "Like a real woman."

"Then the cock I stroke just exist in your head, right?"

"Right."

"Then it must vanish when you try to touch it."

"Yes." John's eyes were again fixed on the therapists big cock.

"But if it doesn't vanish, it proofs that it really exists." Dr. Valentine declared. "Then I'm not really a woman, but a real shemale with a big cock, just like you like it."

John nodded. His eyes had gotten wider as he thought about her really being a shemale and not just his fantasy.

The doctor took her hand off her semi-erect cock and grabbed John's hand. "Then let's find out what's true." She moved his hand to her cock.
