A simple bet on a board in town.
"Enjoy Your Cock More - Guaranteed".
An offer of double your money back...
Now, when you get there, you find out she doesn't actually charge a fee for her services helping you achieve sexual actualization and greater pleasure with your penis, but the offer to help you is sincere.
The strange hospital on the outskirts of town is home to many 'professionals' of dubious or otherworldly origins. The counselor is a source of pleasure, but it comes at the price of obsession. The more interested in her you get, the more pleasure she derives from your presence, the more she desires you, and the more you both get involved, the darker and more mutual the obsessive contact becomes. She is in your dreams. She is the source of pleasure, of your newfound climax.
She seems detached, distant, and not overly interested, at this point...
But you've got to give a little, to get a lot.
And what is an occasional tentacle between friends?
