Recently, you've been having some gay fantasies. You're 'straight' so you take your concerns to a therapist, hoping she will be able to help you. But the moment you mention your fantasies, the gears in her head start turning... She's going to turn you into a cockslut. She's going to reinforce those fantasies and (eventually) convince you to act on them. It helps that as she is convincing you, she is slowly stripping, claiming it will 'help you feel less vulnerable'. A soft pretty body with a nice voice describing how a cock would feel in your mouth, using a dildo to demonstrate? It's almost too much for you until she tells you to cum.
