Okay, so a little background here: in the chat room on the morning of this posting (AEST time), we were treated to the appearance of Rachel_t's younger sister, Sophie. After Sophie departed, I chatted with Rachel and asked if she was okay with me doing a story about both of them. She agreed, and this is it...well, it will be when I finish. (As with Breaking Chris before it, I'm still writing this one as I'm posting it. So it'll also be in flux.)
Now, I really had to think about where to put it. Should it be Incest? Does it fit better in Gang Bang? I ended up choosing Mixed Groupings because of the gangbangs during the breaks in between.
Now, the usual warning: This story is fictional, and contains rape, both gangbang and of a pseudo-gladiatorial nature. Engaging in any kind of non-consensual sex will get you seeing jail time, especially of the form that is detailed here. Seriously, don't copy any of what I write about here, I don't care how tempting it seems.
The large round room looked a lot like the Colosseum, the people's seating areas raised high above the floor. Belts, floggers, ropes and insertables hung from the walls in the main "battle" area, along with pairs of looped ropes located at four fake doorways. In the center was a wooden box with ropes looped into its top and sides. Two doors faced the long sides of the box. Just above the spectator seats, jutting out a bit from the edge, facing one short end of the box, was a seat for a special spectator.
One by one, the spectators filed into their seats. Once they were full, a man, mid-40s, wrapped in a toga, walked to the box. This man called himself the Master of the Games. He stands at the edge, and waits.
Two naked blindfolded young women, held tight by two heavy-set men apiece, were led into the arena. They struggled hard against their captors, but they would not give. They were brought to the box, standing on either side of it, and were let go by the men. "You may remove your blindfolds, ladies." The pair removed them, and were greeted by the cheering masses that had gathered in the seats above to see them.
"Rachel," the younger one, Sophie, whispered, frightened, "where are we?"
"Your guess is as good as mine, sis," her older sister Rachel replied just as quietly, and just as confused.
"Greetings, ladies," the Master called fom the balcony. "You have both been selected to battle it out in our Sexual Colosseum." This statement caused a cheer from the remaining spectators. "You shall battle to make the other girl cum as much and as best as possible, and I shall decide the winner at the end of each of three rounds. Whoever doesn't win at the end of each round shall be subjected to a horrible suffering."
The crowd cheered again, as Sophie looked at her older sister with the look of, "What does he mean?" written across her face. Rachel's face responded with a look saying, "I have no clue either."
"If you win more rounds than your opponent, then you will be let free. Otherwise, your freedom shall be forfeit." Sophie looked acro at her sister again, and saw her look change from that of worry and anguish, to that of someone who wanted to win. She shook her head and mouthed, "Why?" "Challengers...begin!"
Rachel was quick to get around the table to her little sister, making Sophie back away towards a wall. Rachel's arms wre outstretched, like she was reaching for a part of her. She reached up, and her hand found one of the rope loops; she could use this to her advantage. Rchel lunged towards her, and she darted out of the way, looping her sister's wrist in the rope. She tightened it, disallowing her a chance to escape. She grabbed the other loop, and put her sister's other wrist in it. he stopped for a few seconds, catching her breath, and looking for what she could do next. A studded paddle leapt out at her, and she immediately pulled it off the wall, and, holding it in both hands like a baseball bat, swung at her sister's naked ass.
"Ow!" Rachel screamed. "Not so hard!"
"I don't care!" Sophie responded in kind, still swinging her paddle. "I saw the look in your eyes, you were ready to betray your own sister for freedom! Why!?"
"What did you—OW!—want to do instead?"
"I dunno! Escape, maybe! We could try and find a way out of here."
"Sophie, look—Ow! Stop that!" Sophie lowered the paddle, letting her sister speak. "Look around you, Sophie. We're surrounded by people ooking for a show. They know what we look like, and they will probably try and stop us. Now look at the doors." Sophie's eyes darted to the nearest entryway. "Two guards posted on each door. They'd stop us before we could get anywhere. So, what's the only choice we have?"
Rachel had a point, and Sophie knew it. She dropped the paddle to the floor, and collapsed in a heap next to it, where she started to cry.
Rachel found some give in the ropes holding her, and pulled her arms close enough together that she could unloop them from her wrists. Whatever temptation she had to try and get one over her little sister melted away whn she saw her crying, and instead just sat and consoled her.
Thirty seconds of this elicited a fake yawn from the Master. "Forget it, I'm cutting this round short. This lovey-dovey family protectiveness shit make seem nice to you two, but we came here for was a fight! So, I'm making my decision now." And he stood in his box, extending an arm with his fist clenched. He waited fifteen seconds before he stuck his thumb out to the side. A roar of exhultation erupted from the crowd.
Rachel had noticed. "What? What does that mean?" she asked loudly, as the guards from each door came and grabbed the girls. "What are you doing? Sophie!" She pulled against the grip of her guards, while Sophie just kicked and sccreamed, as they were led from the arena.

Rachel was pulled into a room where a group of men and women, mostly naked save for the masks they wore and, in some of the women's cases, strapons, stood around waiting for her. She was thrown to the middle, and the door closed behind her. The crowd started milling around her, then one hand forced her head down to meet a long, hard cock. She kept her mouth shut, but that didn't last long as another pair of hands pulled her hips up, allowing them (a she, Rachel surmised) to push their strapon into her cunt, making her scream out; the scream was quickly muted by the pulsating member that had been waiting in front of her.
It went on like this for some time. Rachel was forced to suck a cock or dildo (or, in one case, a pussy) while another cock, dildo or set of fingers raped her cunt or asshole, both penetrating her until they came or got bored. All the time they hissed at her, "I hope you don't win; I want to keep using your little body," and, "You'll never win if you keep protecting her." The words hurt even more than what penetrated her.
Sophie's perdicament wasn't any better, as she was forced to endure the same labours and insults as her older sister. She had kept crying since she left the arena, and by the time it was ready to go back out for a second round, her eyes were red and she had nothing left to give to her sobs.
