Sister-Sale

//Feel free to write your own continuation. I'm curious what you'll come up with. I'll write some more myself eventually.

Your name is Lia. You are a teenage girl that lives with her father and his family. After your mother disappeared when you were 10, your dad remarried a beautiful woman and they had twins together. Your adorable little sisters, Katia and Zuki. Your parents left the house yesterday, leaving you to take care of the girls. It annoyed you that they left just one day before your 18th birthday, but at least your sisters would be with you. You fell asleep looking forward to tommorow.

You woke up due to a weird rattling noise. You tried moving, but you couldn't. Your eyes went wide and you tried to shout for help, but all you managed to make was a gagging noise. You were completely immobile. You suddenly saw a flashing light as a tarp was removed from around you and you were finally able to look around.

"Oh look! Big sis is awake!"

You were in a cage inside a strange room. There was nothing on you, save from some risqué underwear. Katia pulled out the tarp and called Zuri.

'What is going on! Katia! Let me out!'

"What is big sis saying Katia?"

"I don't know. I can't understand you sis, but you woke up just in time. It's almost time for the market to open."

Upon hearing that, you looked around and realized that this place was familiar. It was a closed market that your parents often went to when you were little. What were you doing here?

"I just finished the sign! How does it look big sis?"

Zuri pushed a small carton sign against the cage. It was a not for sale sign, with '38$' spray painted on top.

'What is happening!? Why do you have that!?'

"Mommy and daddy said we could do whatever we wanted, as long as you weren't home anymore. And there is this really awesome new novel called 'The new master'. We asked daddy where we could sell you, and he drove us here!"

You couldn't believe what you were hearing!

'Sell me!? No! Let me go! Let me gooo!!!'

Alas, your screams meant nothing. You heard doors opening, and an influx of people started coming in, opening various stalls. You were flabbergasted when you saw the contents. From weapons to bondage gear and **** devises, to literal women tied to the walls. This was an underground black market. Zuri placed her sign in front of your cage.

"Do you have the note Katia?"

"Yes, I have it right here! Mommy said we should learn it if we want to sell sis."

The girls started reading from a piece of paper, and started trying to escape. But to no avail. Soon another set of doors opened and a crowd of people started coming in.

"Costumers! Okay here we go!

They put the paper away and started yelling.

"Sex **** here! Sex **** here!"

"Quality blonde! Able to service you both in the house and in the bed!"

"Are you having a barbecue sir!? We have a quality meat-girl here! Have her service you and your friends before you put her over the coals!"

"You can fuck her! You can snuff her! You can sell her!"

As your sisters were shouting the most horrifying thing you've ever heard, someone came up to them.
