Obey and try to escape later

One of the girls takes you to the stables and tightens leather straps binding your arms behind your back. She forces you to use a bit gag with bridles and she immobilizes you to work on the details.

"Lesson one" she says "Don't struggle or the pain will be worse, it's always your choice"
She pierces your nipples and you moan and struggle in pain...
"I told you... stop struggling, I will pierce your nose too"
And she pierces your nose and puts a heavy ring on it. You have never experienced this pain, and you cry, trying to move away.
The strict girl spanks your ass and say "If you keep struggling, I can continue the whole day, you will have piercing even in your anus"
With tears in your eyes and biting the bit gag you endure the painful piercing on your pussy lips. This time, you don't move.

"Good girl" she says and pats your head. She attachs chains to the pircing on your nose and pussy and bells to the ones on your nipples.
She forces you to bend you body, and says "Now push with your ass as hard as possible, or the tail will not fit"
What? The tail???

The accessory is thick... too large for your ass.
She adds lube and says "Hold still, struggle, and I’ll be worse, you already know that."

You bite the bit gag, forcing your body to remain pliant as she works with the monstrous plug. The stretch is agonizing, and you are relieved when it slides in and your sphincter has a moment to rest. However, the full sensation is terrible, and you are sweating.
But you don’t fight. You’ve learned that lesson already.

"Perfect," now, let’s see how well you perform under pressure."

She unleash the ropes, and with a sharp crack of her whip against your ass, she sends you stumbling forward.

You look at her confused, trying to know what to do, and she answers "Lesson two, you don’t walk. You trot."

Days pass, you’re **** to walk with elegance, rear up on command, and even jump over obstacles. The girl rewards "good behavior" with fresh food and fruit and punishes hesitation with the whip.

Every night, she scrubs you down with brushes, inspecting your body like livestock. "You’ll learn to enjoy it," she assures, and you try to relax, because it's the only moment of the day when she's nice with you are takes care of your wounds using special potions.

You are her best horse, and when the noble lord sees you, he can't recognize you...
The priestess laughs and congratulates the girl.

Bad ending
Noble mare ending
