Attack them

You try to cast a spell, but your magic energy is absorbed by the mirror. A deep, echoing laugh sounds in the room.
The priests and nuns ran away, scared.

"Oh, a little witch" the mirror mocks. "Did you really think that your cheap tricks are a match for my power? I will never allow you to kill him, his soul is mine... we have a deal"

The deformed lord giggles. "Yes! We have a deal, trap her, trap her! Don't allow her to harm me!"

You see a flash, and then, you are trapped in a room full of light with only a window.
You are inside the mirror!

"Please mirror break her and let me enjoy her pussy!" The little lord says from the other side.
You try to hit the window and break the glass but it's pointless.

The mirror answer to him "Tomorrow she will be ready. Your wish will be granted"
This is insane, you will never allow him to touch your body.

Suddenly, you are undressed, and your clothes are replaced wedding gown of white silk, its lace tightening around your throat like a lover’s fingers. A bouquet of flowers materializes in your hands.
You try to move, but you can't... You hear a horse's sound behind you.
And the mirror says, "I now pronounce you horse and wife."

The horse pushes your body, he's trying to mount you like a mare... you feel his warm erect cock pocking your pussy.
Terrified your struggle, the contact with the animal's cock makes your stomach revolt.
But the mirror says "You will enjoy it, you are now a mare, you only want to be fucked"

You start to drool, with a silly smile on your face and you make ridiculous horse sounds.

The next day, the mirror lets you go to please his deformed friend.
Acting like a mare, you enjoy his cock and you return to your prison with the horse... Your mind is broken, and you don't have a terrible life; you can only feel pleasure, joy, and your broken holes don't hurt.

Bad ending
