Fight to the end

The goblins thought the special aphrodisiac potions would break you.

The potions meant to reduce you to an obedient creature, but you fight inside your mind...
The goblins notice that the training is not working and they try something else.

The training is with the saddle and the whip.

They fit you with a leather harness. A bridle for your mouth and neck forces your head up. Your hands are bound and your legs are left just free enough to move, but not to run.

They lube a wooden plug and they laugh watching your face when you feel the big plug entering your anus. They also inserts another one in your pussy, witch a chain and a bell attached.

They lash you forward, making you march like a beast, a rider month on your back, and guide you through the camp.
You resist at first, but after many months, you can't endure more whipping and torture. You start to obey and your life becomes easier.
They load packs onto your back, laughing when you stagger under the weight.

Finally, a rider claims you as his personal mount, and you are bound to him, you have to follow him everywhere, he takes care of your cleaning and feeding.

You serve him until you are too old and tired to be useful and then you are discarded like an object.
This is the end of your story.
