I had ordered you to kneel, chest forward next to a fucking bench, and had blindfolded you. You heard me greet a number of people as they came into the room, who started chatting and making both appreciative and derogatory comments about your body on display. Eventually, at some signal you couldn't see, the crowd quieted, and I started to speak.
"Ladies and gentlemen, slut here has agreed to play a little game tonight, but she doesn't know the rules or the other players. Let's fix one of those right now"
I remove the blindfold, and you're greeted by about a dozen folks, a mixture of femme-presenting and male-presenting, some of whom you know and a few you don't. What they all share is a piercing, hungry look directed at you.
"Take a good look, slut, you won't be seeing much of anything for a while" I say as I put the blindfold back on.
"Now, I think she needs to get into position. Any volunteers to help?"
An uncountable number of hands lifts you up from your kneeling positing and manhandles you over the fucking bench, taking multiple opportunities to twist nipples and labia and drag fingernails on skin. Once laid over the bench you are buckled in, completely restrained, face down.
"Now, let's explain the rules of the game to slut. Right now, my associate is attaching four weights to the main attraction; one for each nipple and one for each labia. This chest of condoms is yours to use, you already know if you're on the list that doesn't need one. Each of you is allowed to fuck slut as much as you like, but the game is this. If slut can tell, just from your fucking of her, that you have fucked her before, and she yells "Yes!" one weight will be removed. If she yells "yes" and is wrong, then whoever is currently fucking her gets to spank her ass 50 times. If any weights fall off naturally in the course of events, they will be replaced. After some light restorative massage of the area, of course. We're not monsters."
The crowd gives an appreciative chuckle at this as you squirm and start getting wetter at the implications.
"Since vocalization is going to be critical to the game, slut's mouth is unfortunately off limits. The game ends when either she guesses correctly four times, or you all give up on exhaustion."
