Door number 3

Still recovering from her recent orgasm, Nicole stumbled out of the theater, deposited the second key, and made her way to the third door.

If the last room was dark, the room she had just stepped into was the polar opposite. It was too bright, like a medical clinic. It even had a front desk. For a moment, Nicole was frightened these creeps were into body modification, but then she heard the cheap-ass relaxation CD. It was a spa! The thought of a spa in the dungeon would have been weird to her before, but she had been to a sex shop and a theatre to this point, so not much surpised her any more.

She approached the front desk, and was met by a tall, lithe blonde, who was naked, and wearing a collar. Another of the voice's slavegirls.

"Do you have an appointment?" The blonde asked, almost bored out of her mind.

"Uhhhh no" Nicole replied. "I'm actually looking for a key to the door in the hallway."

The blonde's eyes lit up, and she looked Nicole up and down, and for a moment Nicole felt naked in front of her (or at least more naked than she already was, if that was even possible) as she reached down and produced a key "you mean this key? Normally I make little prudes like you work hard for their keys, but I left my strap-on at home. Fortunately for you, I've got a one time only better deal for you. One of my massage slavegirls is getting railed by her last client, and she's too.... occupied to take her final booking of the day. You take her last customer and make sure he leaves satisfied, I'll give you the key. Sound good?"

Compared to the thought of the strap-on, everything sounded good. "You've got a deal" Nicole replied.
