It's time for you to finally confess to your psychologist your obsession with fat girls.  "I should have know" she says, "that's why you chose me, right?" It's the truth. You looked for pictures of all the therapists in your town to find the one that best met your aesthetic criteria: a pretty girl with a fat belly.  "You don't have to worry, what will happen here will be our little secret. To my colleagues, my methods are unethical... but I want to make my patients feel good. That's my mission." She unbuttoned her blouse, and began to play with her fat belly, inciting you to masturbate on her to "free" yourself from the mental burden of carrying this secret passion inside for years.  Surely from now on your weekly sessions will be much more interesting!
