You cast your most powerful spell, a fireball. It erupts from your fingertips, a brilliant, roaring sphere of flame, the explosion hits the dragon, and you can't see a single scratch on his scales. A single swipe of his tail sends you crashing into the cavern wall and you know that the difference in power is just... too much

But he doesn’t kill you.
"Foolish little human" he takes you with his claw, scratching your body "You dare to attack me in my own home... Now you’ll learn to serve"

And you do... He casts a magical wall on the cave and you are trapped.
Now, you serve, cleaning his treasure and also his intimate parts, you try to escape at first and you will never touch his cock, but after cruel punishments and days of starving, you obey.

The dragon's claws make you lay on a rock and he puts his cock over your body, he says "Clean. Properly". You struggle, but he forces you to obey... you gag at the first touch of your tongue, but he looks at you, and you understand that you don't have any option... is that, or endure more punishments.

Each involuntary gag makes him laugh and once you finish, he turns back and shows you his ass.
"No, please no..." you beg...
But the dragon is not joking and you understand what you have to do.

You move closer to the soft ring of his scaled rear. You hesitate for a moment but you have no choice... Your first attempt ends with you gagging, spittle dripping from your lips as you recoil. He laughs and say that he prepared a special torture tonight if you can't continue... after that his voice rumbles again.
"Clean. Properly. Now!"

Tears blur your vision when you obey, each stroke of your tongue drawing another wave of nausea, your throat convulsing as you feel the smell and taste. He doesn’t rush you, the dragon doesn’t care about your retches, only the slow, meticulous worship of your servitude.
When he’s finally satisfied, he releases you with a gesture of his tail, leaving you on your bed.

After months, his scent no longer makes you gag, his rough demands no longer fill you with dread. Instead, you get used to it and he has his cock and ass perfectly clean. You memorize every inch of his cock, all his anal folds, and the way his breath changes when you do it right...

You shouldn’t get used to it, but you lose any hope and you are trapped here forever.
It's pathetic and humiliating, but this is your end. You’ll never leave.

Bad ending

Task: Lay on a table, rub a big dildo on your face, pretend to gag, and lick it clean. Warm-up and lube a pocket pussy, imagine the dragon's ass and reluctantly lick it for 2 minutes. Pretend to gag and act disgusted. Repeat both tasks, but kiss the cock and the ass and act humiliated. You are allowed to cum.
