The central platform.

You feel a tug on your leash as you are led to the centre of the room. You lay down on the platform, face first. You feel your hands tied to the top corners of the bed, with your ankles to the bottom corners. A small, wedged cushion is placed below you, pushing your ass high in the air. Your Master places an open-mouth gag between your lips, and chains your collar to an O-ring at the top of the platform. You cannot move your head more than a few inches (mostly to allow for you to suck cock and nothing else) and you are left completely exposed in the centre of the room.

You feel yourself getting wetter. You love being on display like this, and you know that your Master can't refuse fucking you when you are tied up like this. You stare at the eye-level bulge in his pants, eagerly awaiting the removal of the pesky fabric that is in your way. To your surprise, he turns to make an announcement to the room.

"Good evening everyone. This lovely toy here is mine, and I do love putting her on display. However, this evening she will be available for anyone to play with, and is the bottom of the food chain. Submissives AND dominants are welcome to her, as she needs to learn her place and to follow the rules. Please enjoy her, as she will do anything she is told. If she doesn't, please feel free to punish her as you see fit."

With this, he turns back to you and grins.

"Have fun. I will be back later. I hope you learn your lesson."
