Dr. Valentine stopped John

After some time Dr. Valentine grabbed John's hair and pulled his head back. Her cock slid out of his mouth. With wide open mouth and eyes John looked up to the therapist, as he didn't knew what was happening. "That's enough fun for you at the moment." She said. "If you want more, you have to do what I tell you." She saw the unsatisfied desire in John's eyes and knew he would do everything she asked him to do just to suck her cock again.
