Place you on your knees in the living room and fasten your wrists to your ankles, a restrainer bar fixed between your ankles to make sure you're nice and exposed, perfectly presented: face down and ass up.
You're exhibited like this for my party and it's a while before my guests start to arrive, so naturally you become impatient, but your excitement mounts as the doorbell starts to ring and I go to greet my waves of guests as they arrive. You can barely catch a glimpse of them but they watch you closely and you can hear how they talk about your body, either admiringly or dismissively.
There are lots of people, men and women, they start to casually grope you, slapping your ass, reaching under you to grab your tits, poking and prodding at you curious to see whether you're aroused and find out how your holes feel.
I kneel down and grab your hair, lifting your head to show you the picture of you I posted in the group chat, your plump arse and sticky cunt taking prime position. Obviously this has given all the guests time to think about how they'd like to use you. Some want to work you with fingers and toys to find out how many times they can make you cum, how much stimulation you can endure, some want to worship you with their mouths, others just want to fuck you like a slut and use you til they're emptying their balls inside of you.
By the end of the night you'll no longer remember how many times you've cum, how many people have been inside you, how many loads you've taken but you will remember being positioned there, a little party slut, every time you masturbate and it will become your go to image when you need to make sure you make yourself orgasm so fucking hard.
