===Taboo===
(Vocaloid, Kagamine Rin, Kagamine Len, smothering, necrophilia, consensual, casual)

“Taboo, huh”, Rin uttered. “So that’s what it’s called”.
“Did you say something?” Len didn’t quite make out through the headphones.
Len was sitting at the computer, watching a review of a not so new but still unrivaled wild west game. The footage showed gorgeously picturesque sceneries of the game’s open world, which looked more like old painting masterpieces coming alive rather than videogame graphics, and the narrator expressed his love to this perfectly captured atmosphere with a soothing voice full of sincere fascination. Even though Len has beaten this game himself a couple of times for different endings, videos like this still never failed to captivate him whenever he stumbled onto one.
And as Len’s mind was all engrossed in admiring the beauty on the screen, he didn’t even notice when his left hand started rubbing his dick. After all, never bothering with wearing clothes indoors left it in easy access, so absentminded masturbation like this wasn’t an uncommon occurrence when he was watching videos or even reading texts. The only reason Len didn’t do it while playing games too was because most of those required both hands. So even when he paused the video and turned to face his sister, his left hand automatically continued its job.
Rin was on the bed just next to the computer desk, lying on her stomach with a pillow under it, as she was reading a paper book. Contrasting this outdated medium was a holographic bracelet on her left wrist, which was the only piece of clothes she was wearing. The bracelet was currently linked with an egg vibrator in Rin’s pussy, and she was so used to adjusting the power with a swipe of a thumb over her fingertips, that it felt as natural as if she was playing with her body directly, but this way she found to be less distracting from reading. Rin seemed to have her mind deep in the book, and when Len spoke, she turned her head to him in confusion.
“What?” she asked.
“I thought you said something”, Len pointed out, still with his dick in his hand.
“Ah”, Rin finally realized, “I must have been thinking aloud”.
“Okay then”, Len nodded.
But before he returned to his video, Rin decided to elaborate further. She made herself comfortable turning to her side completely, now laying with her stomach facing Len, as she continued:
“There was a line in the book, saying: sexual taboos, such as incest, pedophilia and necrophilia”, Rin said, “so I thought: uh-huh, so such things are called taboos”.
“What things?” Len got interested and took his earphones off. Using both hands for it made him stop masturbating, leaving his dick stand erect as if it too was waiting for an answer.
“Apparently, especially fun types of sex”, Rin answered. “For example, incest is having sex with close family, like, you know, with one’s twin”, she playfully flicked her brother’s dick and giggled at its pendulant reaction accompanied by a drop of pre-cum.
“Oh, I know that one very well”, Len giggled back, as he caught Rin’s hand and turned her vibrator all the way to max.
“Kya-a-ha-ha-ha!” Rin’s surprised scream quickly turned into laughter, as she hurried to turn her toy off while her body was squirming in orgasm and wetting the bed. Or more like, with the way she doubled up, wetting the pillow.
“Mhm”, Len moaned, watching his sister cum, “it’s almost like I’ve felt it myself”.
“Yeah”, Rin agreed, restoring her breath. “That’s what makes incest so great”.
She assumed a sitting position for the conversation, putting the wet pillow onto her lap and resting her forearms on top of it.
“So what other of those… things…”
“Taboos”, Rin reminded.
“What other taboos were there?” Len asked.
“The next one was pedophilia”, Rin recalled. “It’s when adults join in with us, kids”.
“Join in having sex?” Len specified. “That might be rarer than twins”, he laughed.
“Yeah, usually adults are too boring for anything fun”, Rin sighed. “Such a waste of their big dicks”.
“Oh, I’d love to see a big adult dick pounding your pussy”, Len took his right wrist into his left hand, his thumb and middle finger barely meeting. “Maybe it’ll make you bleed like the first time again!”
“Ha-ha, too bad putting your dick into an adult hole won’t work the same”, Rin laughed, making a wide ring with two hands around her brother’s still quite erect organ. “But I guess watching you gag trying to suck an adult dick could be fun too”.
“We should definitely try this pedophilia one day”, Len concluded, his dick regaining its erection just at that idea. “Meanwhile, what was the last taboo?”
“Let me see”, Rin picked up the book and put in on her lap. “Necrophilia”, she has read aloud. “Huh, I actually don’t know this one…”
“Maybe sex with black people?” Len suggested. “I’ve heard they also have big dicks”.
“I wonder what black adults must be like then?” Rin said dreamily. “But anyway that’s not it”, she handed the book to Len, “see, it’s spelt with c, not g”.
“Huh”, Len chuckled, “so does it mean we’re missing out on something else that’s just as fun as incest and pedophilia?”
“Apparently”, Rin agreed. “But then it also means we’re about to discover this new type of fun to explore!” she figured, her excitement growing. “Come on, look it up”, Rin nodded to the monitor.
“Sure thing”, Len nodded, catching his sister’s mood, and putting the book on his desk to carefully copy the spelling.
As he turned back to the computer, his left hand almost automatically slid down to his dick, before he realized he needed it for typing and had to retract it. Noticing this, Rin stretched her legs and rested them on Len’s lap, so she could fiddle his dick with her feet.
“Thanks”, Len said, but a moment later sighed in confusion as he looked at the search results: “huh?”
“What is it?” Rin slightly leaned in, trying to look at the monitor, but it was awkward as she also didn’t want to let go of his dick or let the pillow slip down to the floor.
“It says necrophilia means having sex with a corpse”, he pointed out, “see?”
“A corpse?” Rin became as confused as Len and even stopped moving her feet for a moment. “How’s that supposed to be fun?”
“No idea”, Len made a helpless gesture. “But it does call it a taboo here too”.
There was a moment of silence, but then Rin spoke again.
“Alright, I think I get it!” she said as she put her feet to use again, twice as intensely as before.
“Yes?” Len asked, turning back to her, careful not to push her feet away.
“Think how before we actually discovered masturbation, we couldn’t even imagine how fun playing with our pee-pees could be”, Rin pointed out.
“That’s true”, Len agreed, gently stroking Rin’s feet with his hands as her feet were stroking his dick. “Just to think we only used them for peeing, ha-ha!”
“And peeing also turned out to be much more fun than we imagined”, Rin noted.
“And many other things”, Len nodded actively. “Some sounded quite ridiculous, but ended up being really fun”.
“So, this necrophilia must be the same”, Rin concluded. “If we can’t imagine what’s so fun about it, then it must be fun in a way we can’t yet imagine!”
“Ooh, that sounds exciting alright!” Len agreed.
And apparently his dick agreed too, shooting a load of semen, most of which landed right onto the pillow still on Rin’s lap.
“Ha-ha, nice shot!” she smirked. “But you should’ve saved it for this brand new necrophilia fun!”
“What do you mean?” Len asked in confusion. “It’s not like we can try it right away”.
“Why not?” Rin shrugged.
“Like, because we don’t have a corpse at hand?” Len wondered how it wasn’t obvious. “I don’t even know where the nearest cemetery is”.
“Ha-ha”, Rin chuckled. “Cemetery would have only bones left anyway”.
“So what do you suggest?” Len made a helpless gesture.
“Corpses are made by killing living people”, Rin pointed out. “And there are two of us right here”.
“Oh”, Len realized, “haven’t thought of it that way!” he laughed.
“Being twins has a lot of benefits, doesn’t it?” Rin smirked again.
“Sure does”, Len agreed, still laughing, and also getting aroused again at the prospect of not just trying a new kind of sex, but doing it with his twin sister too: it was two taboos for the price of one! “So do I kill you, or do you kill me?” he asked, seeing no difference either way.
“I’m looking forward to try necrophilia…” Rin started. “I’m not looking forward to getting a dead willy up!” she concluded and burst into laughter too.
“Ah, right, sorry”, Len blushed for not realizing it himself. “How should I kill you then?”
“Here, take this and smother me”, Rin gave her brother the pillow and laid back on the bed, gleaming with anticipation. “It will probably hurt, but don’t hold back, okay?”
“Of course”, Len agreed understandingly. “The sooner you’re dead, the sooner it stops hurting”.
“And the sooner the real fun begins”, Rin grinned widely. “Whatever it might be!” having no idea in what exact way necrophilia was going to be fun made the anticipation of that fun all the more exciting.
“You’re really looking forward to it, don’t you?” Len chuckled.
“Of course!” Rin nodded eagerly. “A whole new kind of fun is waiting for us to explore it! This…” the excitement made her speech abrupt, as she stopped mid-sentence to catch a breath.
“This sexual taboo of necrophilia”, Len read aloud from her eyes, properly savoring the words on his tongue the way he saw her wanting to do it.
Rin nodded, appreciating his help in ending the sentence for her when she was out of breath.
“So nice to be twins, isn’t it?” Rin noted. “I can hardly wait for all the new untasted sensations my death will bring us!”
“Nice is an understatement”, Len replied. “Makes me really appreciate how special of a bond it is when I see you being even more excited about your death than I am, ha-ha!”
“But of course I’m the one to be excited”, Rin pointed out the obvious. “Because it’s you who’s going to have all the fun!”
Such a line overwhelmed Len’s heart with love that he needed to take out right now, and so he climbed onto the bed on top of his sister and kissed her lips as briefly and delicately as he could. It was almost as if their lips never physically touched, but all the while their souls intertwined in a most intimate embrace. This exalted sensation calmed both of the twins down a little. They were still looking forward to a great fun, just not choking on that anticipation.
“Good night, Rin”, Len whispered gently, preparing the pillow in his hands.
It felt almost like he was holding a blanket about to tenderly tuck her in.
“Thank you, Len”, Rin replied, really grateful for such mundane yet nonetheless genuine care.
“Sleep tight”, Len concluded and finally pressed it against his sister’s face.
“Tighter than ever”, she thought warmly, closing her eyes for the last time.
Rin tried to take a breath through the pillow. It wasn’t completely blocking her breathing, just making her inhale mostly the same air she just breathed out. Along with the heavy scent of her own urine and her brother’s semen. Len was considerate enough to turn the pillow the soaked side to Rin’s face. Although really through all the fun times the twins had on this bed, all of their pillows became so thoroughly soaked in their bodily liquids that no amount of washing could remove the odor anyway. Not that they wanted to remove it. The twins loved the smell and loved sleeping on the soaked pillows, as the smell soothed them. And so as Rin was breathing in the mixed products of her own and her brother’s orgasm, she felt no discomfort yet, but only relaxation.
“Oh…”
Rin felt the pressure on the pillow ease a little as Len seemed to realize something. For a moment she thought he was going to stop and even felt a slight twinge of annoyance: she was just getting so comfy! But her worries turned out to be unfounded.
“Light off”, was what Len said.
And even through her closed eyes and pillow Rin noticed how the room became dark, now illuminated only by the computer monitor. She had no idea she needed this until she felt how much nicer it started to feel as Len proceeded to press the pillow harder again. The atmosphere just became so much more fitting.
Rin reached out for her brother and gently caressed his hair.
“I’m so happy to have such a caring brother like you”, she was trying to say through the touch.
“And I’m happy to have a sister like you to care for”, Len replied, knowing his twin well enough to perfectly understand. “Here, let me wet the bed for you”.
And as he said so, Len let his bladder loose. His position crouching over Rin made his pee hit her chest first and then as the stream weakened it slowly travelled down her body, making sure to splash all over it. And of course as the urine trickled down Rin’s sides it thoroughly soaked the bed under her. Ever since the twins discovered how fun playing with pee was, there was hardly a night where they slept in a bed not totally drenched with it. Having a liquid part of each other all over themselves was almost like a type of cuddling, only liquid could cover one’s body much more thoroughly than another body, getting into every nook and cranny. So naturally as this familiar wetness spread all over and under her, Rin welcomed it dearly. If not for her breathing becoming more erratic as her lungs started to notice the lack of new air, Rin could almost forget Len wasn’t simply putting her to sleep.
Although, it’s not like he really wasn’t. Obviously, she was going to lose consciousness before dying for good, so Len was indeed putting her to sleep, he just wasn’t going to stop there. At least she hoped he didn’t, it would ruin the whole fun if Len mistook her unconsciousness for death and removed the pillow too early. They could of course always try it another time, but Rin wasn’t sure that after having gone through the pain of suffocation she’d remain as willing to experience it all over again. On the other hand, there must be other ways to die too, she just chose the pillow because it happened to already be in her hands.
But even though her lungs were starting to burn, Rin was also glad she chose the pillow because of how it lead to this set up with Len putting her to sleep. Going to sleep came along with anticipating the new day and all the new fun it would bring, starting with the very wake up. Lately it became somewhat of a tradition among the twins that whichever of them woke up first would come up with a fun way to wake up the other. Like Rin would suck Len’s dick, or he would shower her with pee. But of course this time there won’t be a wake up or a new day. Instead there was something much more fun to look forward to! A whole new taboo to explore — necrophilia.
The excitement at this thought made Rin remember she still had the egg vibrator in her pussy. So with a gesture of her hand Rin turned her toy on again, realizing it could both scratch her arousal and distract her from the pain. Her legs twitched, although Rin herself was unsure if it was from the jolt of pleasure in her pussy or the increasing physical distress in her lungs. Whichever was the cause, Len noticed her movement too.
“Having trouble sleeping?” he said, and through the joke Rin heard honest concern for her pain in his voice. “I think I have an idea how to kill you a bit quicker”.
“Thanks, I’d like that”, Rin tried to convey her grateful smile through a gentle touch of her brother’s cheek, although her fingers didn’t want to listen very well.
She was happy to hear that her end could be brought closer. Even though she wasn’t yet in so much pain that she couldn’t bear staying alive, any shortening of the suffering part was welcome. But mainly Rin longed not so much for the death itself, as for what would come next. The mystery of what made necrophilia so fun to deserve being called a taboo was waiting for the twins to discover it!
In the meanwhile Len was enacting the idea he mentioned. It appeared to consist of him repositioning himself in a way that let him put more of his weight onto the pillow, thus smothering Rin more efficiently. Moving was a bit awkward while trying not to remove the existing pressure, but in the end Len managed to make himself seated on the pillow facing Rin’s feet, while his own feet were tucked to the sides of his butt. Len had to brace his left hand against the wall and his right hand against the computer desk to keep balance, but most of his weight was now resting on the pillow, pushing it hard into his sister’s face.
Rin immediately felt how harder it became to breathe. Now not only there was no supply of new air, but even the remaining air was hardly moving in and out of her lungs. The burning in her lungs became much more acute, and the distress she managed to dismiss so far tried to grow into a full-scale panic. Rin was happy to see that she was nearing her death and the following exploration of necrophilia, but she urgently needed a distraction from the physical suffering, so she turned the vibrator’s power up. It helped a little to bear the pain, but the sexual stimulation happened to be similarly contributing to the chaotic movement of her limbs. The mix of torture and pleasure made them flail around almost as if in search of something.
“Don’t worry, Rin”, Len promised, “the more you struggle, the harder I push”.
This was reassuring. Rin certainly didn’t want Len to think that she was trying to wrestle free and release her. She didn’t want him to release her even if she did try to wrestle free! Rin wanted to give Len another grateful touch, but found her hand hard to control.
“Ow!” Len yelped in pain as Rin’s right hand slapped his balls. “That hurt!”
He knew it must have been hurting Rin much more to be suffocating, but it didn’t make his own pain any more welcome. Rin thought the same, so her genuine desire to make up allowed her to will her hand into submission at last, as she stroked Len’s sex parts gently to ease the pain.
“Were you looking for a bedtime toy?” Len wondered. “Alright, feel free to cuddle it if it helps you sleep well”.
Rin wasn’t really trying to search for Len’s dick. Or was she? She wasn’t sure, as suffocating made it hard to thing straight. But either way she liked the idea. Rin focused her mind on wrapping her hand around Len’s dick. She didn’t have enough control to purposely stroke it or to stop her whole arm from continuing to flail around, but those two issues kinda solved each other. Her arm’s twitching translated into her hand jerking Len’s dick, and she only needed to focus on keeping her grip, which was exactly what she did.
Len was watching Rin’s throes in fascination. He knew she was in great pain, but he could recognize the pleasure too, and they were intermixed in a way he would have never believed they could if he wasn’t seeing it with his own eyes. But in retrospect it seemed like a natural form for a physical representation of anticipation. The joy of knowing that a great fun is coming, mixed with the anxiety of it hot having come yet. With every twitching of Rin’s body Len felt how much she was looking forward to necrophilia, and with every jerk of her hand on his dick he felt how her wait was coming to its end. As Rin’s grip on it was getting weaker and weaker, Len’s dick was getting harder and harder.
Rin herself became unable to distinguish between her own pain and pleasure anymore. As her mind was slipping into darkness, she wasn’t even aware that her right hand was still trying to hold onto Len’s dick while her left hand was turning her vibrator’s power to maximum. The only thing Rin knew was that she was finally dying, and it filled her with delight that the true fun could begin at last. Rin had never felt this happy before. At least not as far as her mostly already faded mind was concerned, as it was too far beyond to actually bother trying to recall happier occasions. Why dwell on the past anyway, when the immediate future promised so much fun! Granted, Rin had no idea what the appeal of having sex with a corpse was, but that only made trying it out all the more alluring.
Not that Rin would be the one to try it out, of course. She was always well aware of that. What being dead really meant was not being at all, so she simply wouldn’t be there to actually experience anything, no matter how fun it was going to be. This much was common sense. But thankfully, Rin was a twin. Just one of the two. So it didn’t bother her that she wouldn’t get to enjoy the fun herself as an individual. The fun will be enjoyed by the pair of twins as a whole, of which both she and Len were each only a part. Masturbating one’s own self doesn’t make the hand sorry that it doesn’t get a fair share of pleasure. And thus, while Rin fully understood the concept of death, it posed no contradiction to looking forward to necrophilia with all her heart. Knowing she wouldn’t get to experience the fun didn’t make her anticipation of it any less sincere. Rin was the twin longing for this and Len was the twin who would have it fulfilled: it all worked out for the pair as a whole. Not to mention that the way a necessary key to uncovering the mystery of necrophilia was leaving herself in the dark about it only made it all the more mysterious and thus more tempting. Rin could hardly wait to discover it in a way only possible for a pair of twins.
And she had to wait no longer. Rin knew it was her last dying thought when she noticed her body approaching an imminent orgasm. Her body has built up such immense pleasure about to erupt, it practically brought the otherwise already dead Rin back to life for a moment just so that she could feel it. Rin used this moment to gather all of her remaining willpower in her left thumb, straining to control the vibrator. Just a little bit… could she actually do it?.. how far could her own fingers possibly be… there! The vibrator was turned off and the orgasm was avoided. She wouldn’t want to finish before the main event even started, would she? She had to end first! Or at least that’s probably how Rin would’ve phrased this joke had she not successfully died before the joke itself was over. But of course, not getting to enjoy the laugh only made it all the funnier. Rin didn’t feel a modicum of regret about depriving herself from the last bit of pleasure, because there was simply no Rin anymore to feel such regret. Isn’t that neat!
Meanwhile, Len was also on the edge of orgasm. When Rin’s right hand was already barely touching his dick, it felt a lot like the twins’ special delicate kiss. Two souls intertwined once again, but Rin’s rapidly melting away, and from nothing else but the heat of Len’s soul’s loving embrace. The fleeting weakness of the physical contact was only emphasizing the overwhelming emotions, and Len had to put conscious effort not to cum right away. Not merely in order to save it for when Rin is properly dead, but also to ensure that she does get properly dead: even if Rin wasn’t twitching as hard now, Len still had to actively brace himself to keep his butt pressing the pillow into her face. Len’s body and even mind ached for the sweet release, but he knew it couldn’t possibly compare to Rin’s longing for death. May it be that she wouldn’t be around to thank Len afterwards for his unwavering devotion, but that didn’t matter because right now she was still alive and fully worthy of it. As long as there was Rin, Len would be there for her. Loving her, cherishing her, caring for her with all of his heart. Until her very last moment.
And he knew that moment came when suddenly Rin’s hand let go of his dick completely, falling limp to the side. Not even the most delicate touch remained to stimulate the organ, but the implication behind this gesture brought Len’s mind into such exaltation that he couldn’t keep it inside. It erupted in a blissful ejaculation, even more continuous and copious than before. Len’s body tensed and relaxed and he wasn’t even sure what it was doing anymore, as he just closed his eyes and focused on the delight that his sister was now dead, while his dick kept shooting rope after rope of semen onto her body. No, her corpse, Len corrected himself happily. Len was so glad he held out until her death with his orgasm. Rin loved Len’s semen in any form on or in her body, but with how much she looked forward to necrophilia she wouldn’t have wanted to feel it on her belly before she was dead. And maybe simply cumming on her corpse from prior excitement wasn’t proper necrophilia yet, but now Rin wasn’t around to be disappointed about it. For the first time in his life Len didn’t have a twin sister to care about, so he was free to just revel in his own pleasure. Neat indeed!
Len wasn’t sure how much time he spent in nirvana, but when he came back to his senses he discovered himself collapsed on top of Rin’s corpse, glued to it with a thick layer of his semen mixed with his pee from earlier. Len’s face ended up right against Rin’s pussy and he saw a trickle of his sister’s urine coming out too. It looked almost as if she couldn’t hold it back from laughing too hard at her own death, which perfectly complemented Len’s especially incredible orgasm. Len smiled warmly, as such a combination felt like the most fitting joint reaction of the two of them as a whole to the death of one of them as an individual. Rin would have loved to see this, and Len getting to see it for her was as good in the twins’ book. One can never observe themselves being dead, but two can have one half of them observe the death of the other half. A unique experience that only twins can have.
Len climbed off Rin’s copse and got up from the bed. A-ah, he didn’t even realize how numb his legs became. Even through the pillow Rin’s face wasn’t exactly the most comfortable seat, ha-ha-ha! Len took his time stretching his legs, walking back and forth around the room. After cumming so hard he’d need time to recharge anyway. And thankfully, as much as Rin had been hardly able to wait to try out necrophilia, that was only while she was alive. Len didn’t have to consider Rin’s sake now because there was no Rin’s sake. There was no Rin.
But it wasn’t in a way that with her death Len suddenly stopped caring. His love and cherish, all of his own feelings for her were still there, what was gone was only Rin herself. The deep emotional bond between the twins was never severed, just the other end stopped advancing in time and remained in the past. And only there in the past there existed Rin who was looking forward to trying necrophilia. In the present there was no such person. In her anticipation Rin had already had all the fun she was ever going to have with necrophilia, and once she was dead nothing could change this fact one way or the other. So Len’s lack of concern wasn’t from a position that he didn’t care. It was from a position of confidence that nothing will ever be able to affect Rin’s already happened fun.
And thus Len was in no hurry. He was also curious about necrophilia, of course, but Rin’s corpse wasn’t going anywhere, so exploring the new taboo could wait until his dick had some rest. For now Len decided to examine the body first. After all, it was his first time seeing a dead one. Len came up to the bed again. Rin was still lying there, covered in his cum, almost as if she just fell asleep in a weird pose. But her skin has already gotten distinctly pale, giving out that her sleep was an eternal one. The pillow has slipped somewhat from Rin’s face, but not entirely, so Len had to remove it to look at her face. He wondered what he would see in her final expression. Turned out a whole lot and nothing at all.
Rin’s face was distorted in pain, but not too much as it was also relaxed in relief at the suffering’s end. Above all however Rin’s expression was full of optimism for what would come afterwards. Her face was so blissful that if Len didn’t know better he could’ve thought his sister was looking forward to eternity in heaven. But of course the twins didn’t believe in such nonsense as afterlife. It was just how much hope she had built for necrophilia. That seemed to be quite an unreasonable expectation to live up to! Thankfully, Rin wasn’t around to get disappointed. Perhaps knowing this was what made her feel free to set her expectation so high in the first place. If the anticipation was all she was going to get, there was no reason not to anticipate to the fullest.
The impression changed entirely however when Len carefully opened Rin’s eyelids with his fingers. He commanded the room’s light to turn back on so that he could better see his sister’s empty eyes. But it was not the lack of usual gleam or reaction to the light that caught his attention. What really emphasized the absence of Rin behind her own eyes was how her gaze was completely devoid of emotions. When Rin was alive Len needed only a glimpse of her eyes to know what she was feeling. Now no matter how closely he stared into them he couldn’t make out anything. All of the pain and relief on her face were merely engraving of her past experience, and in the present there was simply nothing. Not just nothing on her mind, but no mind at all. Even the very blissful hope that inspired her to die to begin with was now gone along with Rin herself. She wasn’t suffering and she wasn’t rejoicing, she just wasn’t.
Len on the other hand totally was. And Rin’s dead state positively amused him. Fascinated even. Len had been always taking her existence as a given. She was his twin after all, his inseparable other half. The idea of not having her by his side was something that had never crossed Len’s mind. And so even if he had just taken her life with his own hands… or his own butt… it still felt surreal. Like it was all just a dream and in the morning he would wake up and laugh about it together with a very much alive Rin. Len wondered if he would ever actually get used to his twin’s death. He imagined there were going to be many little everyday occasions where he would habitually be considering what to make his sister for breakfast or alternatively wondering what she intended to cook for him only to realize a moment later that he had no such sister. That sounded like a lot of fun!
But Len reminded himself that he didn’t kill Rin for the fun of contemplating her death. He killed her for the fun of having sex with her corpse. His dick felt like it had enough rest, but it still had to be made erect again. And what could help better than some foreplay? Len started with gently touching Rin’s unnaturally pale cheek with the back of his fingers, almost like if trying not to wake her up. It felt cold. Even though Rin’s corpse didn’t cool down too much yet, the lack of warmth was very apparent. To get a better feel Len caressed Rin’s cheek with his palm next. It let him sense not just the lowered temperature of the skin, but the way the body underneath did not generate any heat. Len loved how it accentuated that his sister was not merely hypothermic, but actually dead. He reveled in knowing that no matter how much of his warmth he would give her, Rin wouldn’t receive any of it. Where did it go? Such a fascinating mystery!
Mesmerized, Len leaned in for a kiss. The kiss. Bringing his lips right up to hers, and no further. This was always enough. But not now. Of course, the physical sensation of the barely happening touch was still there, even if Rin’s lips felt colder and dryer than usual. Yet, as Len’s soul reached out for Rin’s to embrace, it found nothing. Len pressed his lips stronger as if trying to search deeper, but to no avail. Len smelled the familiar scent of mixed semen and urine, faintly remaining on Rin’s face from the pillow he smothered her with, but Rin’s breath wasn’t tickling his face in return. Len looked right into her empty eyes, but only saw her staring back right through him into nowhere. This was not a kiss, Len realized with a hint of annoyance. How could he kiss Rin if she wasn’t there? All he was doing was shoving his face against an inanimate object. These were still the same lips, but they were no longer Rin’s. Even if all of the parts were intact, they didn’t sum up to his sister anymore. Something immaterial that made this body not just a collection of meat and bones, but a person known as Kagamine Rin, was irreplaceably gone. All of this was filling Len’s heart with sheer delight, yet as much as he appreciated Rin’s death, what was he expecting from kissing her corpse?
Right, he was trying to make his dick hard, Len remembered, as he pulled back. Perhaps it just wasn’t the right way. This kiss was never about sex or even tactile sensations, the emotions were what made it special. So there was no point expecting it to work on a dead body. Wallowing in his sister’s death was exciting alright, but not exactly in a sexual way. Len figured he should try something different, something more physical. A blowjob always worked great and Rin enjoyed giving it maybe even more than Len enjoyed receiving, although Rin’s death made that point irrelevant. What it made relevant on the other hand was that without her contribution a blowjob was bound to fail even more miserably than the kiss did. What was Len going to do, rub his dick against her lips? Pull out her tongue so he could rub against it too? Len burst into laughter, imagining how silly that would look. Maybe another time he could try doing so just for the hilarity of it.
For now though, Len decided, if a blowjob isn’t an option, then good old handjob it is. Len seated himself on the edge of the bed, half-turned to his right. Not so much to face Rin, as there wasn’t such a person anymore, but just naturally keeping her corpse in sight as the focus of the whole endeavor. Len took his sister’s right hand into his own. It was totally limp and pliable, like a ragdoll. And when Len was thinking of ragdolls he wasn’t thinking of actual dolls made of rags, but of the character physics in old videogames. The game he was watching a video on tonight had a more sophisticated technology where characters would grab onto things as they fall or try to hold down the hurt body part, just like living humans would. But Rin wasn’t living, she was just like in those games they played when they were little, and Len smiled to that memory. Nostalgia for good old times was an unexpected result of killing his sister, but not an unwelcome one!
Still, there was a deed to be done, so Len proceeded and wrapped Rin’s hand around his dick. It felt cold and weird. He had to clench Rin’s fist inside of his for it to squeeze him, and even then it felt unnatural. Although it made perfect sense that no Rin could give him no handjob, Len hoped there’d be some sort of a novel pleasure as his dick rubbed against dead flesh. He didn’t know what it was supposed to be exactly, but whatever necrophilia was considered so good for should at least partially apply to fucking a dead hand, shouldn’t it? Instead it wasn’t any better than masturbating on his own. Worse even, as Rin’s hand was only getting in the way without doing anything useful and by now it cooled down enough for the temperature to be uncomfortable for his dick and counterproductive to making it erect. Len disappointedly put Rin’s hand aside and switched to using his own. But now he started doubting if necrophilia itself was going to live up to its status as a taboo. Well, there was only one way to know, which was exactly why they killed Rin in the first place. Len was just glad it was his sister who got to be dead: this way he could at least take the matter of physical arousal in his own hands. Leaving Rin trying to figure out what to do with a dead dick would’ve been much worse for sure!
It took some time, as the skepticism creeping in Len’s mind didn’t help, but finally his tool was ready for the job. He climbed onto the bed, crawling over his sister, and aimed for her pussy. Well then, this was the moment of truth where he was going to find out what this whole necrophilia was about. Len inserted his dick into Rin’s slit, prepared to experience a whole new sensation… but encountered the egg vibrator. Oops! Totally forgot about it. Len pulled out, but it looked like he had already pushed the toy deeper, so now he couldn’t fish it out with his fingers and Rin wasn’t there to help by pushing from inside. On the other hand if Rin wasn’t there it also wouldn’t hurt her if Len went the other way and just shoved it even further instead. And so he did with several extra deep thrusts until he felt like the egg didn’t get in his way anymore. Effectively Len was already fucking the corpse, but the focus of his mind was on removing the unexpected distraction, not paying attention to the sensations necrophilia brought. That just won’t do. Len pulled out and took a deep breath to restore his concentration.
Take two! Len inserted his dick into Rin’s slit, prepared to experience a whole new sensation. Nothing yet. Len started moving back and forth. Still nothing. He tried adjusting the angle. Nope. It was absolutely the same pussy as always, only not as warm. At least on the inside Rin’s body didn’t yet cool down as much as on outside, so it wasn’t unpleasantly cold. But there wasn’t any special pleasure either. More importantly, the emotional aspect of sex was totally gone. For the twins it was always more about each other’s pleasure than their own, but now there was no Rin that Len could give pleasure to. He still enjoyed the experience of having his other half dead, the experience of them as a pair of twins having one of them dead, it was really unique and emphasized the special bond they shared. And he could even appreciate how Rin not getting any pleasure from his dick enhanced that experience too. But turned out it didn’t work the other way around. Despite what necrophilia promised, Rin’s death didn’t enhance sex, it wasn’t sex at all.
It takes two to have sex. Or more than two. But doing it by oneself was just masturbation. And Len was now indeed doing it by himself. Just because the corpse used to be Rin didn’t make it her. It wasn’t a partner in the game of sex, it was merely a toy to play with. So having sex with a corpse was just a figure of speech for masturbating with its pussy. Of course, this much was obvious from the start. But that only raised the twins’ expectations further. After all, if using a corpse as a toy was listed alongside incest, the best type of sex, then it had to make one hell of a toy! And Rin was especially looking forward to it, as she had grown to love this kind of toys a lot ever since Miku introduced her to them. Her corpse promised to make a toy to top all toys, so Rin couldn’t possibly let such a thing go by. And the way the twins always cared for each other more than for themselves meant that Len being the one to get to enjoy this toy only made the prospect all the more alluring for Rin. Knowing there was no way for her to have it for herself had sent her expectations for this fun through the roof. Her death was going to give Len the greatest sexual experience ever. She had no doubt.
Len had no more doubt too. No doubt that there was nothing special in fucking a corpse. It was probably still better than an artificial vagina, being a real one, but it had no person attached to it just the same. And thus it didn’t even make a difference that it was not some random corpse, but his sister’s. Without Rin herself inside it was just a body like any other. When Len had thought how trying necrophilia with his sister would double as incest, in his excitement he seemed to miss the whole point of it. The reason the twins loved sex with each other so much wasn’t because the pleasure from it was something special, but because they were giving that pleasure to someone special. And now that someone wasn’t there. The same aspect of caring for each other more than for themselves that filled Rin with so much hope for necrophilia had led to Len’s utter disappointment in it. Having his one and only most beloved other half being dead was by itself a truly unearthly experience that Len couldn’t be more delighted about, but it made fucking her pussy utterly pointless.
Instinctively responding to Rin’s lack of pleasure by trying harder to give it to her, Len held her in embrace. The twins always loved cuddling, probably more so than sex, but of course these two pleasures could be easily combined together. So, as Len’s hips kept thrusting, his arms pressed Rin’s body against his own with all his strength. After all, no matter how hard he squeezed the corpse, Rin wouldn’t be hurt. But it also meant that no matter how hard he squeezed the corpse, Rin wouldn’t return the embrace. The only response was her refreshing coldness trying to cool down his passion. But a response wasn’t necessary if at least she could enjoy it one-sidedly. Yet Len knew she could not. Rin wasn’t even indifferent to his touch, there simply was no Rin.
Len feasted his eyes on his sister’s dead face. Its blissful expression engraved her optimistic hope for enjoying a new unimaginable type of pleasure. And her empty eyes explicitly indicated a complete lack of any enjoyment. Not even the simplest physical stimulation Len could still feel from their sex organs rubbing. Len was so glad that his sister was dead. With how high her expectations were, it would’ve devastated her to learn how bleak necrophilia happened to be for real. Thankfully, Rin has already had her part of the fun, and with her death ensuring she would not experience this disappointment, Len was genuinely happy for her. But unfortunately, for himself the same reason has caused this disappointment in the first place. What was the point of fucking Rin’s corpse if by doing so he couldn’t give her any more pleasure than she already had?
As Len’s arms got tired of squeezing his sister’s body he let it go and took her hands into his instead. To his surprise Rin’s bracelet reacted to his touch. It was still hooked up to the egg deep inside her pussy. Encouraged by this discovery, Len turned the toy on and increased the power until he could feel the vibration transmitted to his dick. It was still nowhere near as good as having sex with a living Rin, but certainly much more of a new exciting sexual experience than simply fucking a dead vagina. The so-called taboo of necrophilia was so overrated that even this simple egg made a better toy!
Thanks to this enhancement Len was finally able to reach his third orgasm for the evening. He even produced some sperm, but it didn’t matter without Rin enjoying the sensation of it pouring inside her. Instead of satisfaction Len felt more of a neutral sense of completion, like finishing a job. He gazed at his sister’s face forever frozen in delightful anticipation and found comfort in her empty eyes staring into nothingness with no idea how everything played out. Len moved from being on top of Rin to lying next to her on his side to have a rest, and As he restored his breath, his mind was also clearing up. The bitter disappointment lost its vividness and gave way to less emotional judgement. The twins wanted to try out what necrophilia was like and try it out they did. Sure, it turned out to be no fun, but that was a valid conclusion too. Not every movie, book or game always happened to be to the twins liking, so there was no reason why every taboo had to be. That might be just a matter of taste. The twins had figured out necrophilia was not their thing, so there was no reason to linger on it. Perhaps pedophilia would work out better.
As Len climbed over his sister’s body to get off the bed he couldn’t help but think once again how lucky she was to be the one made into a corpse. Among the two of them Rin had undoubtedly gotten the best half of the experience. It was hardly the intended way to enjoy necrophilia, but Rin still had a lot of fun with it. Even if it was based entirely on the anticipation of Len’s fun, his fun never happening could no longer shatter Rin’s hope thanks to her being dead by that point. The fact that there was no Rin anymore was the best thing to come out of this whole endeavor. From now on for anything bad that would ever happen to Len, Rin wouldn’t get to share the pain, but for anything good she also wouldn’t be missing the joy. And it worked the other way too. For Len there was no more worrying about bad things happening to Rin, but likewise no more worrying about good things not happening. There simply was no Rin for any of those things to happen or not happen to. Her life had been complete, like a finished book or a beaten game. And what a fitting conclusion she got for a twin: filled with optimism for the other twin. Len couldn’t imagine a better end for Rin. Nothing could possibly make him more happy for her.
There is no way to express how much Len loved his sister, and her death did nothing to change his love. But it removed Rin herself from the equation, leaving Len free to let her corpse be and returned to the computer. The browser was opened on the page with the definition of necrophilia, and for a moment Len wondered if the word taboo in it might have meant something different. But before he could consider checking its own definition, Len noticed the title of the other opened tab. Right, he had been watching quite an enjoyable video before Rin distracted him with this whole taboo thing, and now he could responsibly conclude that he liked the video better. So he closed the necrophilia tab and returned to the video.
Once again Len was relaxing as he watched picturesque sceneries of fictional and yet so real American landscapes. So what if people called this game horse butt simulator. It didn’t matter what was on the screen: a physically rendered rainbow over a sparkling waterfall or a close-up of vultures tearing apart a half-decayed corpse, this game managed to pull it all off with equal beauty. Speaking of corpses… Rin had said they couldn’t use one from a cemetery because it would be rotten down to nothing but bones. But the video just happened to go over how there are quite a few stages in between a fresh corpse and a bare skeleton. And as detailed as this game was, in real life the decay would be happening even more gradually. So it occurred to Len: what if this was their problem with necrophilia? Of course, a body that had just died wouldn’t be yet so different from a living one, so it was silly to expect it to feel much special. But once it has rotten somewhat, that was where the whole new experience must be supposed to come from. Now it made perfect sense! And it meant that the twins were going to have their fun from necrophilia after all. Excited by this discovery, Len turned to his sister to give her the good news.
Oh, right. He didn’t have a sister anymore! Len had burst into hearty laughter. The twins always felt sorry for children without siblings. They couldn’t imagine how lonely life must be for an only child. And now more than ever Len was grateful to had been born with Rin. Only as a pair of twins they could enjoy this transcendent experience of having one of them be dead. Len was on cloud nine. Rin was no more. And together they never stopped being one whole.
