Use ice knife

The goblin runs to you with his magic sword, and you cast an ice knife on him. However, he manages to dodge it and he hits you with his chain. The chain is attached to your neck, and he forces you to fall to your knees.

He casts a spell with his word and before you can do something, you are engulfed by the shadows and teleported to an empty room.

You feel weak, you can't cast spells, and the goblin laugh. The voice sounds inside your mind again.
"Welcome to your new home, I'm the treasure goblin, I already told you, you will be my anal whore... relax and spread wide."

Weakened, you try to resist, but it's impossible, the goblin **** you to stay on all fours, takes you from the chain, and mounts you like a bitch.
His cock slides inside your ass and you scream in pain, he fucks you fast and deep, so fast that your ass burns and you beg him to stop.
Inside your mind you listen to his voice "Relax anal whore, you are doing well, soon you will be so loose that I will fit my whole head inside you"

Defeated, crying in pain, you can only endure this terrible humiliation.

Unfortunately, the Treasure Goblin is right, after some time, your ass is so loose that he makes you experience the most ****, disgusting, degrading, and painful practices... you are his anal whore, and this is the end of your story, living with him under the treasure.
