Apologize and give back the gold

You slowly turn around, your hands shaking as you put the three coins back on the ground. "I'm sorry," you say. "I was wrong to try and take your treasure. Please, let me leave."

"So you can return with an army to slay me and take my hoard?" the dragon says, climbing down from his pile of treasure, scattering coins and jewels across the floor. He's not as big as you thought a dragon would be, his body barely larger than that of a plow horse, but with a long neck and tail, and huge leathery wings folded tight to his back.

"N-no! I wouldn't tell anyone, I swear!" you say.

"And I should take the word of a thief?" the dragon hisses, examining the three coins you tried to take. "The only way I can trust your word is if you earn the riches you tried to sneak off with. Then I might believe you."

"Earn how?" you ask. "I-I'll do anything."

"For three coins, I will require three tasks," the dragon says, his forked tongue flicking out. "Refuse or fail in any one of them and I will be **** to eat you."

"Sounds fair," you say, your mouth dry. "What are the tasks?"

"Oh, let's not rush this," the dragon hisses. "It's been centuries since anything this entertaining has happened." He pauses to rub the side of his face against the base of a stalagmite, flaking off a few dry scales. "I know. For each task, I'll give you a choice and you can pick which one you'd rather do."

"That sounds very generous," you say.

"It does sound that way, doesn't it?" the dragon says with a smirk. "First, take off your dress. Let me look at you."

"Is that one of the tasks?"

"No, that's a request. If you refuse, I could always burn it off of you."

You quickly strip off your dress and drape it over a nearby slab of stone. You fight the urge to cover yourself as the dragon steps closer, his glowing golden eyes moving slowly over every inch of your body.

"Interesting," he says at last. "Your scent is unique, both male and female. Are there others of your kind like you?"

"Not that I've ever met," you say, "but I haven't really looked, either."

"Hmmm..." The dragon makes a thoughtful noise, his long tongue flicking out and tickling your breasts, making your nipples harden. "Yes, I think this will be most entertaining." He turns away, slithering back over to his hoard, where he claws at the pile, using his long snout to dig through the treasure. After a minute, he returns to you, several items clutched in his talons. You can make out little except the glitter of gold and the flash of a ruby.

"First task," the dragon says. "You may choose between gold, jewels, or pearls."

"What kind of a choice is that?" you ask. "It tells me nothing about the task, or what I'll have to do. It's not fair."

"When did ever say this was going to be fair?" the dragon says, exposing hundreds of teeth as he smiles. "I'll try to make the next choice more informative. Now choose, unless you'd rather I just eat you."
