Follow the music and the sounds

The music grows louder. You push through the final bush in the forest to see a nightmare circus, makeshift tents stitched from animal hides, cages stacked with creatures and humans, and goblins playing instruments, and using the creatures and the humans for entertainment..

You turn to flee, but dozens of goblins emerge from the underbrush. One giggles as it shoots a blowgun to your butt. You feel a hot sting and the last thing you see is a goblin with a big purple hat bowing over your paralyzed body. "Welcome to my circus, silly human, you’ll love being part of the acts…"

When you wake up, you can't move freely, something is wrong. Your hands are bound inside stiff hoof-gloves and you are wearing heavy boots with hoofs. A bridle digs into your cheeks, and mouth the metal bit pressing your tongue down as goblins cackle and adjust the reins. They’ve dressed you in blue and golden colors, they arranges your hair with a ponytail but you feel a terrible pain in your butt and nipples.
Horrified, you notice the big golden piercings on your exposed nipples, you want to cry, this is a nightmare... also when they **** you to stand up, you feel something big inside your ass, and you moan in pain. You struggle, and you try to push it out, the goblin laughs and say "Push all you want, little pony, the plug is well secured inside your dirty ass, and you are ready for the show"
You moan in pain and you drool through the bridle in your mouth. The goblins continue to explain.
"Wouldn't want you shitting yourself like some panicked mare during the show" he mocks at you, patting the buttplug tail lodged deep inside you. "This stays in until we say otherwise, so hold tight, pony-girl." The crowd's laughter echoes as he pushes you from your nipple rings and forces you to walk in front of everyone.

Your “debut” as their newest attraction has begun. You are **** to march, jump, avoid obstacles and they whip your ass when you fail.

Completely sweated and tired, the nightmare stops and the goblin with the purple hat lets you rest inside a tent. He makes you drink fresh water and takes off your bridle to let you speak.
He explains that the goblins are happy with your performance, and he can earn more money with a new act.
He asks you if you have acting skills, and perform a fake wedding, you are beautiful and the goblins will love to see you as a sexy bride.

You are humiliated, the degradation is **** and you don't know what to do.
If you accept the role, maybe it's better, but also, you don't want to continue to act like a ponygirl and the plug inside your ass is killing you.
