Explore the right branch, the temple (male)

In complete darkness, you walk inside the mountain, you smell the molten metal and smoldering embers, the place is more like a temple carved in the mountain instead of a cavern.

Unfortunately, you fall into a pit and you are badly hurt, but a group of small reptilian creatures save you. They heal your wounds, but tie your arms.

They explain that they serve a superior being, a dragon, and that you must answer to him. You are in his territory.

There is light in the next chamber, the bright glow of a dragon’s hoard. A massive dragon rests on a mountain of gold. He looks at you and smiles. The creatures leave the chamber, leaving you alone with him.

"Ah, a new servant, how... convenient."
He moves a collar made of iron with his mind and orders you "Put it on and take off your clothes"

What?? this creature is insane or what the hell is happening here?

He notices that you are doubting and says, "You will serve me, tend my hoard, warm my lair, and obey my commands and of course, serve me as my sexual pet with my other female human pet. I need a boy too; you will be fine..."
He exhales a cloud of black smoke and says.
"Displease me, and I will use you as entertainment for my kobold slaves"
