Pankration

"Oh here! This one is my favorite!" Liz pointed to a thumbnail out of the dozen visible on Kubler's console screen in the transcription bay. He dutifully selected it to see a high-res image of her pussy being penetrated by the cock of her twin brother, Ross. Her smiling face was clearly visible in the background, a mirror of the face she made as she bent over the transcriptor tech's ancient desk to peer at his monitor. Kubler couldn't imagine why this particular pic would be her favorite out of the hundred or so the twins offered him as payment for their illicit transcription use, but he readily agreed with her all the same.

"Ah yes, the composition is quite good! You should definitely look into taking your photography skills to a professional level."

"Really? You think so?" Her mouth made an inquisitive moue that reminded him of the 'innocent' face she adopted in several of her photos, usually while being covered in her sibling's ejaculate. Ross, lost in thought in the office's only other chair, broke his reverie to give Kubler a knowing smirk at his obvious flattery. He was well aware that the only photographic composition that mattered to the portly low-level tech was that the frame of the picture contained attractive blond sixteen-year-old twins fucking each other. The man was simple to please, Ross was shocked that in the years they'd used the bay for their purposes he'd never once tried to raise their payment, he never even asked for a video of the two, much less any actual sexual favors.

Not that he was complaining. The three of them had a very comfortable arrangement, and the twins had been able to practice their highly unusual habits unobstructed for the last two years. He doubted his sister realized it—she wouldn't be the type to fastidiously keep track of something the way he often did—but the session they were about to partake in would be their one-hundredth in the two year span. Ninety-nine times they had copied one of themselves with the transcription equipment, with the express purpose of ending the new life the machine created from raw material. He felt in no way bored of it—in fact he fully intended to continue the practice somehow for as long as possible—but as his sister flirted with their perverted benefactor, he thought of some way he might surprise his sister on this particular anniversary.

As Kubler left with the disk of images—no doubt to hurry to the nearest private place and take care of the noticeable bulge in his pants—Ross decided on a idea he thought may be interesting.

"Do you want to roll for it?" He asked her as they stripped down in the empty bay. "Not that I'd try to get out of taking my turn."

"Oh no!" She spoke with mock graciousness while pulling her panties off, exposing her freshly-shaven pussy. "I couldn't dream of denying you your fair turn at being tonight's plaything." She curtsied at him and gestured to the waiting transcription pad. Casually he strolled over to it, his hardening cock swinging back and forth.

"Do you need me to set up the machine for you?" He sat cross-legged on the input pad, feeling his balls settle against the cool metal plate beneath him. "I don't want my component atoms to get smeared all over the room or something." Her face threw him the same knowing smirk he had given Kubler five minutes before.

"I do think I know what I'm doing dear brother. Do you know how many times we've played this little game?"

"This makes one-hundred." He informed her, as the machine completed its start up calibrations. "You've personally worked it forty-three times and I've done it the other fifty-seven."

"Wait, really? One-hundred exactly?" She pressed the last button of the sequence before he could respond and the machine read the composition and position of every particle in his atomic structure as it vaporized them, simultaneously encoding them and constructing two identical copies, one on each powered output pad.

"I guess we mostly did me at first." she continued, idly running a finger between her moistened pussy lips. "Maybe you should take a few turns in a row so we can make it an even..." She stopped as she realized both Rosses were off the pad, one coming towards her at the console and the other heading for their toolbag.

"What are you two doing?" She held up the die they used to select which copy would survive their violent sexual episodes. "You guys didn't roll—Hey!"

Ross 1 roughly slapped the die out of her hand, sending it skipping across the room as he forcefully hauled her out from behind the console by her arm. He was easily larger and more powerful than his sister and he had her on her back as Ross 2 approached the struggling pair with a handful of the industrial cable ties they often used for tourniquets.

"What the fuck are you doing? Have you fucking lost it?" They ignored her as together they fastened her arms and legs tightly to the anchor points that were periodically embedded in the deck throughout the entire ship in the case of gravity failure. When they finished, they stood over her to examine their work, their identical erections thrusting out from their bodies at the sight of their sister laying spread eagle before them, completely helpless.

"What is this Ross?" The expression on her face was rapidly changing from extreme annoyance to fearful concern. Neither Ross answered as their moved in concert, one taking up a position at either end of her body.

"We've kind of gotten bored with you, Liz" The Ross at her feet admitted as he began to kneel between her wide-spread legs. He stroked his cock gently with one hand and she gasped as he roughly used his other to spread her pussy lips wide open. He pushed his thumb into her and the Ross at her head spoke.

"We decided that this hundredth time would get to be your turn. Your last turn." He knelt at her head, his cock lightly brushing over her face."

"Ross, you can't be serious. You'll spend the rest of your life in the brig. Why did you need two of you? Why—Oh!" Feet Ross roughly pushed his thumb into her ass, startling her. He began to rub his fingers against her pussy and clit.

"It's what you've always wanted Liz, we both know it." Head Ross wrapped a hand around her slender neck and moved his cock against her mouth, pushing gently. "This has all been practice. It's been just a game. I'm going to destroy you for real now. There's no backup copy this time. The two of us are going to fuck you and then we'll kill you for real." Before she could answer she took him into her mouth and he was surprised to feel her eagerly begin to suck on him. She moaned around his cock as Feet Ross pushed himself into her cunt, which was wet with anticipation.

Head Ross looked down into his sister's eyes and saw no more fear, just the love and acceptance he always felt from her. For a brief second he felt bad about the ruse. If he had actually planned on killing her, he realized she would go along with it.

He hadn't had any intention of actually killing his sister permanently. While he had long ago come to grips with the results of their macabre sex games, the initial murders of Liz had bothered him deeply on a level he hadn't been prepared for, although he had managed to keep these misgivings from her. As far as she was aware, he had always been just as enamored with the process of killing themselves as she was. He knew deep down, that this entire spectacle was primarily for her, because of his love for her. He would be just as content if one day, she decided to completely forgo the whole affair.

The one thing he would never do—not even if she wanted it—was take her life for good. He had merely intended to spook her a bit with the attack, knowing his sister's love of a good practical joke. Her complete submission to him was something he hadn't been really prepared for. The least he could do for her was give her a good, rough fucking before letting her free to pick one of them to be sacrificed. For all he knew, he would be the unlucky one and this would be his chance to have some preemptive revenge.

He gripped her throat and felt his own cock as he pushed deep into her and held it, felt her small frame spasm as she tried to catch her breath and then suddenly, felt her convulse as she arched her back in a powerful orgasm. Witnessing this pushed him over the edge and he groaned as he came, shooting a load directly down her throat, completely caught unaware when, in the midst of his orgasm, he was kicked hard in the face by the other Ross.

Liz had never come so hard in her life and wondered if all of her duplicate victims had experienced this feeling when realizing they would be murdered. Images of what her brother had promised to do to her rushed through her head as the two boys poured their cum into either end of her helpless body. She only realized she had briefly blacked out from either the oxygen deprivation or the intense orgasm when she woke to see the two Rosses trading blows in front of her.

In awe she watched as her two brother duplicates viciously fought in front of her, their cocks already erect again and still glistening with her bodily fluids. One of them was bleeding freely from somewhere on his head and the blood painted their sinewy bodies as they grappled.

She felt another climax building off of the falling wave of the one she had just had, and the torture of being tied down and helpless just heightened the experience. She felt her entire body ache with desire and frustration, which paradoxically only acted to increase her arousal. Every time one of the Rosses landed a blow on the other, she felt her heartbeat jump and pulse through her cunt, until finally, as one of them roughly forced a thumb into an eye, she came without being touched, a stream of liquid shooting out of her.

She was still in the throes of the orgasm when the victorious Ross—one eye bruised but still intact—fell on top of her and buried his engorged cock inside her to the hilt. Almost instantly they both came, her climaxes overlapping as he collapsed onto her exhausted. For several minutes they laid there panting, until the other Ross began to attempt to get to his feet.

She felt the cool air on her cunt as he pulled out of her and stalked over to the other Ross, slamming his head against the decking, stunning him with a single hard blow and strapping him down to the floor like she was.

Finally he returned to his bound sister, stopping by the toolbag to retrieve their boxcutter, and cut away the ties that held her down. She instantly scrambled up and got to her knees in front of him. She held out her hand for the boxcutter and he handed it to her, having no idea what she planned to do with it. Awkwardly, she handed it back to him.

"Brother," She said in total seriousness, all of her earlier mocking gone from her voice, "if you want to kill me, to really kill me, I'd be happy to let you." She gripped his hips and lifted her neck to peer up at him. "You can do anything you like to me, whenever you want. All this..." she gestured to the transcription pad, the bound up body of his double, the tools laying on the floor. "all this is just a way to make it easier. If it's not real enough for you, please, do it for real." She smiled her big innocent smile up at him.

Ross dropped to his knees and took her face in his hands, before kissing her, pulling her into him until he got his fill of the taste of her. As he pulled away, she pushed him to his back and began to kiss him all over his body, lapping off the blood that covered him, gently kissing the bruise where his double had kicked him in the head. She ended her ministrations by taking his penis into her mouth and coaxing it back to its fully aroused state. As he grew in her, feeling her quick little tongue dance around his stiffening cock, he laughed.

"You just can't get enough, can you?" She pulled away, strings of saliva stretching between them as she admired her work.

"Well, I could go again," she admitted, "But I was really thinking about him." She jerked a thumb towards the inert form of his double a few feet away.

The Dead Ross awoke suddenly as his sister spread her cunt lips and forced a stream of urine onto his unconscious face. It didn't take him more than a few seconds of confusion and struggling to ascertain his situation. He looked up into the smiling faces of his sister and himself, and laughed when he saw his victorious duplicate was sporting both a fresh black eye and an engorged erection.

"I guess I lost, huh?"

"I guess you did!" Liz agreed as she placed her foot squarely on his scrotum, pushing down lightly and causing him to yell briefly before he caught himself.

"No chance of some painkillers, I guess?"

"Painkillers are for those that play fair." Real Ross informed him, as he knelt down between the Dead Rosses legs. He poked a finger as his bound doubles cock, quickly stiffening from the painful stimulus. "I don't really go in for that stuff anyway."

"Well not usually of course," he agreed, "I was just worried you two might go hard on me."

"Oh we'll make it HARD on you all right!" Liz proclaimed, smiling as big as was physically possible for her to do. Immediately both Rosses groaned.

"Don't start with the puns Liz, for fucks sake!"

"Please, kill me right now! It's too much—Fuck!" At this Real Ross dug a toe into the side of his subdued double."

"Fuck you, you practically gave it to her."

"You're a real asshole, you know that?" Liz addressed them both as she squatted and lowered her asshole onto the face of Dead Ross. "You know what I want," she flicked the head of his upright cock in front of her. "Make me enjoy your last meal. And you!" She pointed at Real Ross. "Fuck this sack of meat, I want to watch."

"Here, help me out first." He stepped forward and she obligingly took his cock into her mouth, liberally coating it in saliva. As he pulled away, trailing strings of her spit, she pushed the all the cum that her pussy had gathered from both of them over the course of the night out onto the Dead Rosses face, causing him to redouble his efforts in eating her out. As the Real Ross pushed his cock through the tight ring of his own mirrored asshole, the duplicate moaned into her, and she ground her hips against him, quickly reaching a climax while watching his cock and balls bounce around while his asshole was stretched out wide.

Dead Ross had resigned himself to his fate when his double had ruined his eye, exactly what he had been hoping to accomplish with his first brutal attack. A black eye could be explained away easily but a ruined one would be much more trouble, and when only one of them could survive it was reasonable for it to be the whole one. He had abused and murdered plenty of his own duplicates and was horrified to finally be on the receiving end, but realistically he had to expect it would happen someday. The plan of attacking himself was something he had often considered—after all, he reasoned, better to be doomed from losing a fight than from losing a dice roll—and he waited until he thought he had the best chance. As he was fucked brutally by himself, he realized his mistake was waiting until after he came inside his sister to attack. He tried to remember which of them had selected which end of her to fuck first, if he had picked her mouth would he have won? Had his double taken that into account? Was it luck or had he been outmaneuvered by himself? He tried not to think about it and enjoy the comforting taste of his sister's amazing cunt—still delicious despite being tainted with his own cum—and the curious sensation of his ass being spread open wide by his identical cock. He was shocked by how pleasurable it was! He had never really shared his sister's predilections for humiliation and subjugation, especially not to the amazing length she took it, but now that he was actually on the receiving end of his own abuse he found that he could see the appeal in it. He often wondered how the copies of himself he maimed and mistreated managed to maintain an erection through the pain and violence but now—while being assfucked and sporting a grievous head injury and being entirely at his attacker's mercy—his cock was almost painfully hard and his whole body felt electric, like as if in having surrendered completely, some powerful energy that was normally expended on resistance was able to flow freely through him and lead to an ultimate, final climax. He felt that he would come, right now, explosively, with just the lightest touch of his cock, and wondered if his sister knew that as well by the way she completely avoided touching it, his legs jerking helplessly against their bonds in frustration as she lifted her hands over her head.

Glimpsing her smooth, freshly shaven armpits—his favorite part of her well studied anatomy—spread open in front of him, Real Ross grabbed his sister's wrist and pulled her close, the sudden dragging of her clit and cunt over the contours of the tied down doubles body brought her quickly to an already close orgasm and as he brought her armpit to his mouth and tasted the built up fear and lust flavored sweat that had seeped out of her over the course of the night, he too came, pouring his cum into the ass of their victim. Temporarily sated, they rolled off of him and let him soak in his own bound frustration as they nuzzled each other in post-orgasmic bliss.

Dead Ross lay silent, remembering the events nearly two years ago, that let up to him stepping onto the transcript platform himself. They had been doing it already for a few months, ten times he had seen his sister get duplicated and helped her to destroy whichever became the duplicate.

It was their second time using the cable cleaver that he had managed to steal from an engineering tool cart. Liz had been absolutely enthralled with it, the previous Dead Liz—their ninth victim—had her arms sliced into discs as Liz enthusiastically brought the blade down again and again, a few centimeters deeper each time. She also discovered the point at which the blade had trouble slicing through her relatively larger thigh bones.

"Right here." She drew a line on her own naked leg with blood just a little way above the knee. "This doesn't mean my thighs are fat, does it?" She asked him as her duplicate bled out behind her, screaming. He assured her that her thighs were perfectly slim, and talked to Kubler about obtaining painkillers afterwards. The screams that the Dead Lizzes made had begun to bother him.

The tenth Dead Liz, unused to the painkillers dosage, was the first one they tied down.

"I really just think we need a mirror!" she insisted as Ross used his shirt to tie her to one of the anchor points "There's one in the showers! Do you know how many of us there would be then? A lot!"

"No!" insisted Real Liz, equally unprepared for the effects of the drug. "That mirror is way too small! I think I know where a bigger one is..."

"NO!" Ross shouted. "None of us can leave this room right now! You don't have a fucking hand!"

"Oh!" Dead Liz peered at the tourniquet on her stump. "That would raise questions wouldn't it?"

"Oh!" Real Liz stood suddenly with a flash of insight. "We don't need a mirror! Just fuck her eyes out!"

"Yeah! Fuck my eyes out!"

"Right into her fucking brain!"

With a wince of pain from his own destroyed eye, Dead Ross vividly recalled gouging the eyes out of the delirious duplicate. Reaching her brain via orbital socket of course proved not to be possible. However, once she had conceived of the fucking of her double's brain, it had to be accomplished.

"Pull!" Liz closed one eye to stop her double vision and managed to cleanly cleave several centimeters of scalp and skull off of her blind double on the first try as Ross reluctantly pulled on her hair, feeling the piece come away exposing the vital grey matter that made up the soul of his sister.

"It worked!" Dead Liz whispered, the pain at this point overreaching the powerful effect of the drugs. With horror Ross realized that Liz's plan had worked and he has obligated to carry it though. He plunged his erection into her skull and pushed deep enough to feel the sphenoid bone push painfully back against it. The Dead Liz let out the most wretched sound that he had ever heard before her voice dyed away into a repeating whimper.

He didn't know if it was his imagination or not, but to him it sounded as though she repeated:

"I love you brother."

Over and over again as the remaining Liz brought herself to an incredible wailing orgasm behind him.

"Cable ties!" She panted out after taking several minutes to catch her breath post climax.

"What?" Ross was still staring at the ruined corpse of the sister he had murdered as she told him she loved him.

"We need something to tie me down with next time, you're going to have to go back shirtless now."

The next time, he didn't let her do it.

Over and over she asked him if he was sure he wanted to participate in this fashion. He showed her how to use the machine, he gave her the die and instructed her in how to choose between them. He couldn't watch his beloved sister get mutilated again, not without taking a turn himself. He mounted the platform and let it perform its horrible destruction and recreation on his body. As his sister prepared to choose which would die, he felt he was at peace. If he was picked, it would only be what he deserved for the crimes he'd done so far.

Even still, the relief when she rolled the other Ross was the strongest emotion he had felt up to that point in his life. He wondered what was going through his duplicate's mind as he accepted his fate and let the two of them have their way with him.

An hour later and he lay with her in satisfied repose. He felt something rub against his face and looked to see his sister playfully poking him with the remains of his own severed cock.

"Are you sure you don't want a bite? It tastes like I always imagined!"

"I think I'll just eat a few parts of you on your next turn." He reached a hand down between her legs, idly rubbing a few times at her blood-covered clit.

"Oh! I bet I taste even better!" She flung the cock over into a pile of not yet cleaned up waste. "I can't wait!"

Dead Ross lay there and reflected on the two years that had come before, concluding that he certainly deserved what he was getting and deciding that he was lucky to have made it this far before being unlucky enough to end up as the victim. How disappointing though, that he was slated to die, unable to ever again experiment with this position! His newfound role of victim, while demeaning, caused him some degree of arousal. He never expected the level of pleasure that he would reach from the various indignities he had just suffered, being rendered defenseless, being humiliated, even being fucked in the ass was a fascinating and not altogether unpleasurable experience! He briefly thought about telling his victorious double and wondered why none of the doubles he had slaughtered had ever confided as much to him.

He watched as the two twins that would make it out alive this time stirred from their rest as their arousal slowly grew again within them, the stiffening of Real Ross's cock mirrored by Liz slowly extending the blade, click by click, of their well-used boxcutter. His introspection was halted as his dear sister rose up before him, brandishing the tool they'd used on each other a hundred times already before now. How much of themselves had they cut away with that knife? How many cocks and clits, noses and fingers and other easily removable body parts had they removed? He thought desperately of something to say to his magnificent sister as she brought down the knife but words escaped him and his only sound was a hard groan as she brought the point down into the slit of his urethra and he braced himself for what he knew was about to happen.

He managed to not scream as she began to push down, the blade slicing through the bottom of his shaft, subincizing it completely. Blood sprayed onto her but she was careful not to puncture the two larger cavernosa and the organ stayed more or less erect as his urethra was splayed open. His arms and legs began to jerk uncontrollably as the blade reached his scrotum, slicing it apart, both testicles squeezing through the incision as she continued to drag the blade down before thrusting it deep into his perineum, impaling his prostate. This finally caused him to release a high pitched scream, increasing in pitch as she twisted the blade, accidently breaking it off inside him.

"Oh shit!" She whispered, turning around to show Real Ross, who now stood at her shoulder. "I broke our boxcutter!"

"Honestly I'm surprised it lasted this long. It's had two years of use." He stroked his cock idly as he admired his sister's handiwork. "You kind of got carried away with that. I was going to fuck his ass a bit more but I really don't want to risk hitting that thing somehow. What kind of angle did it go in at?"

"Here, I'll get you off." She offered, turning her head to the side to take his cock into her mouth while she extended the remnant of the blade as far as it would go, giving her just enough to work with. Dead Ross watched as she turned her eyes back down to him and used the truncated blade to sever his exposed testicles, carelessly tossing the treasured organs aside rather than consuming them like she may have if her mouth hadn't been full. She took the cock out of her mouth long enough to change positions, turning around to straddle Dead Ross and lowering herself onto his destroyed cock—still moderately erect despite the underside being split apart—giving him a view of her ass rhythmically rising and falling, her back turned to him as she continued to suck off Real Ross.

The sight of Real Ross gripping her hair and coming into his sister's mouth finally caused him to come, his damaged prostate violently expelling any fluid left in it, ejaculate and blood spraying out from between the two of them at the base of his split urethra. At this signal she reached down underneath herself and carefully, almost tenderly used the remaining nub of blade to sever his cock fully at the base, leaving the organ inside her. Quickly she used her legs to push back, gliding her body over the top of him until her cunt was positioned over his face, leaving a bright red stripe up his torso, and he felt his shrinking, castrated organ pushed into his mouth.

Before he could really decide what to do with it, he felt an incredible pain in his left arm, one that dwarfed all the torture and abuse he'd suffered so far. His vision was still obscured by his sister, who was grinding her cunt and ass hard onto his face, but as his left foot exploded in another burst of pain he realized that he didn't have any time left.

Liz brought herself to orgasm twice while watching her brother sever the hands and feet from his double, effectively freeing him from his bonds and causing a wide pool to form from the blood that pumped quickly from the fresh stumps. She pulled away from the double's face finally, only after she failed to feel any movement for several minutes.

She peered into his mouth and was pleased to see no sign of the severed penis she'd deposited in it. She leaned down to whisper in the dead body's ear:

"I hope you liked it!"

Satisfied, she leaned back and took in the signs of the carnage around her, playfully tapping her feet in the deep puddle of gore. Ross held the wide blade of the cable cleaver against his bruised eye, the cool metal easing the pain to some small degree.

"You're probably going to have to go have that looked at by Doctor Etna."

"Yeah," he agreed "It'll raise some questions I guess." He watched his sister closely for any hint of lingering resentment or anger but she continued to idly play with the blood. "That went a bit differently from normal. Sorry about that."

"Oh don't apologize." She rolled her eyes at him. "Watching the two of you beat the shit out of each other was pretty exiting really. Maybe we should do it again sometime, have a battle to the death!" She punched at the air a few times, droplets of blood flying off of her fists. "Oh! Maybe we should copy both of us! Have a four way bout! Why haven't we done that yet? This gives me a lot of ideas!" She eagerly got off of the corpse and raised her arms high above her head, dancing from one foot to the next while spinning about. "Wash me?" She sung to her brother.

Ross sighed at her childish antics and fetched the hose from the wall, smiling as she shrieked when the icy cold water hit her.

"I don't know Liz, that might be difficult logistically, four of us at once?"

She lowered her arm to give him a thumbs up.

"I'm sure you can think of something! After all, this whole thing was your plan from the start, you're brilliant!" She pranced over to him through the stream of water to give him a wet kiss.

Ross, not for the first time, wondered how much of this was really his plan, and to what degree he was a tool for his sister to get whatever she desired. As usual, he concluded that he didn't care whatever the case. His sister being happy was more than enough for him. He returned her kiss before she broke away to drag the ruined corpse onto the recompile stage.

"I'm sure I can." He agreed.
