Refuse

The chieftain’s face twists, then spits on your face. His flesh changes as dark magic surges through him. When the transformation ends, his eyes are burning with power. Furious, he shouts "Then you’ll serve as both my steed and my queen" he sits on his throne and screams "I'm the goblin king!"

For many months, the goblins work on your body, you are permanently blindfolded and you don't know, but they replaced your arms and legs with pig hooves.
You are always with a saddle, pig ears, and a bridle, you also wear a pig buttplug tail, and the king only takes it off to use your anus or to let you relieve yourself.

You give birth to multiple goblin men, and after many years the goblin king announces his crusade against the humans.

Your torment ends in battle, the goblins are destroyed when they attack the city, and you finally rest. The soldiers can't understand what kind of creature are you, and you are buried with the goblins.
