Well, this isn't really guro, but it's something, okay?

Safeword
(Vocaloid, Kagamine Len / Kagamine Rin, BDSM)

“It’s Sunday,” was Rin’s first thought when she woke up and it filled her heart with joy, as it meant a whole other day of carefree fun and games before having to return to school. And if it was going to be anything like yesterday…

Oh, yesterday was a blast! Rin recalled how she and her twin brother Len, currently still sleeping beside her, played at their friends Miku and Flower’s place. And they introduced the twins to a new fun game. It was called something like BDSM if Rin remembered correctly. At first the twins were confused about the idea of deriving pleasure from pain, but their friends were glad to provide a practical demonstration. Turned out Flower had quite a collection of torture tools, perhaps rivalling even Miku’s collection of sex toys. The twins watched in shock as Miku used those tools on Flower, making her scream and cry and whimper. But Flower herself explained that this was all in good fun and she enjoyed it that way. She explained that even when she begged Miku to stop, enduring Miku not stopping was all a part of the game. Perhaps even the part she liked the most about it, Flower insisted. And indeed, as much as Flower looked like she was earnestly suffering, she never attempted to actually fight back. So as the twins kept watching their terrified shock turned into positive astonishment and even reverent admiration for Flower’s endurance. In the end the twins have gotten in the mood enough to join in, and it was only when Len started pushing needles under Flower’s fingernails that she gave up and spoken the safeword. Even then, all defeated and broken, she looked utterly satisfied. Rin remembered vividly that seeing Flower like that made her feel envious.

Len tumbled in bed, drawing Rin’s attention. No good, he seems to be about to wake up. Each of the twins loved the best to be lovingly woken up by the other, so their usual routine was for whichever to wake up first to wake the other up, preferably in some fun and creative way. This time Rin thought she had just the right way in mind. She carefully pushed aside the blanket that was covering their naked bodies and as expected Len sported a proper morning wood. Rin slid down the bed to level her face with Len’s erection and after appetizingly licking her lips took it in her mouth. Should she really do it? Yes, if she wants him to torture her for real and not hold back she should give him some incentive, something he would feel justified taking fierce revenger for. And so she clenched her teeth.

“G-y-a-a-a-a!” Len shrieked in a voice Rin has never heard before. And yet at the same time his dick in Rin’s mouth erupted with copious amounts of semen. “Now, that is fun!” Rin thought as Len pushed her away.
“What the hell?!” he yelled, holding his pained dick.
Instead of an answer Rin pushed back at him and pressed her lips against his, through a passionate kiss feeding him with the materialization of his own bliss. Tasting it made Len realize in surprise that he has indeed just cummed. From having his dick bitten. “Now, that is fun!” he concluded.

“So how was that for a wake up?” Rin asked with a mischievous grin, now sitting on top of Len.
“Well, one thing I can say”, Len answered, still breathing heavily, “the sleep’s gone for sure!”
“Are you not mad at me?” Rin inquired.
“There’s no way I can get mad at you, Rin”, Len ensured. “You’re my other half”.
“Fair enough”, Rin… pouted in disappointment?
“What’s wrong?” Len became confused. “Did you want me to get mad?”
“Well… kinda”, Rin admitted. “I want you to mean it when you torture me”.
“Torture you? What are you talking about?”
“Don’t you remember that BDSM game from yesterday?” Rin reminded.
“Ah, that thing”, Len nodded. “Yeah, that certainly was a lot of fun!”
“Yes, but only getting to watch made me sorta envious”, Rin said.
“And now you want us to play it ourselves”, Len concluded.
“Well, seeing how we have a whole other free day ahead”, Rin pointed out.
“To be honest, I’d love some more BDSM too”, Len agreed. “I was just getting in the mood when Flower gave up”.
“Me too”, Rin nodded. “But since I didn’t think I’d have resolve to hurt you…”
“Oh yeah?” Len raised his eyebrow. “My dick begs to disagree, ha-ha!”
“What I mean is to keep hurting you if you start crying and begging to stop like Flower did”, Rin elaborated. “So I decided to let you torture me first and to give you the resolve I lack I did this wake up… but I’m not sure if it worked as intended?”
“I feel the resolve to torture you alright”, Len ensured. “I just derive it not from being mad, but from my love to you”.
“Love?..” now Rin was confused.
“Of course”, Len confirmed. “When my beloved sister asks to be hurt so sweetly, how can I not indulge her?”
“Oh… so are you trying to say I don’t love you the same?” Rin got competitive. “Just wait for your turn, and I’ll make sure to show you the whole extent of my love!”
“That’s the spirit!” Len approved. “But first let’s go have a good breakfast, we’ll probably need a lot of energy today”.

After the breakfast Rin returned to their bedroom and awaited in nervous and excited anticipation as Len collected the necessary items. Since unlike Flower the Kagamine twins weren’t keeping a collection of torture tools specifically for an occasion like this, Len was instead looking for random stuff around the house that seemed usable for the purpose. In took quite some time, and with each item he brought Rin couldn’t help but start imagining how he’s going to use it on her. It was pretty scary and at the same time thrilling. Rope was pretty obvious, but what was the rolling pin for? And candles too… Wow, Rin gulped, Len certainly wasn’t planning to hold back. She just hoped she could live up to his expectations and withstand all the suffering he was about to unleash on her.
“Well then, this should be enough for starters”, Len declared, putting down a sewing kit.
That’s just for starters?.. It’s going to be quite a challenge to beat it when it’s Len’s turn to get the torture. But first she had to show him how well she could accept his love, that would then be something for him to challenge!
“Now we just have to agree on a safeword”, Len concluded.
“Right, a safeword”, Rin realized. “Hmm…”
She thought back to how Flower screaming “no” and “stop” the whole time, but the torture continued all the way until she used the safeword. Rin was in high doubt she would be able to hold back from using it as soon as she became uncomfortable with the experience.
“Let’s go without a safeword”, Rin suggested.
“Are you sure?” Len wondered. “Flower said it was important”.
“Yeah, but she’s more experienced in withstanding so much torture before giving up”, Rin pointed out. “For me it’ll be the first time, so I’ll probably just scream the safeword at the first sign of real pain… that would be rather lame, wouldn’t it?”
“Whatever you say, my dear sister”, Len obliged. “Well then, let’s start with exploring what is that corporal punishment history books tell of is all about”, he said, arming himself with a belt.

Rin obediently if apprehensively lied on the bed face down, presenting her ass to Len’s mercy. A part of her still couldn’t believe they were doing something this crazy for real, but the other part was eagerly looking forward to testing her limits… and beyond. Rin braced herself and then…
Spank!
“Kya-a!” she still couldn’t help but let out a yelp. Even if she was prepared the strike still felt completely sudden, and the pain, even if not all that bad yet, could not compare to whatever she was imagining just by the simple fact of being real. And then, before Rin could even get her confused thoughts on the matter together…
Spank!
“It hurts!” she voiced, instinctively rubbing her pained ass.
“That’s good”, Len replied and…
Spank!
…right on Rin’s hands, teaching her the hard way that trying to cover herself would only make it worse.
“u-u…” Rin whimpered, forcing herself to move her hands away just in time for…
Spank!
Rin clenched her teeth. Len was right, of course. It was good that it hurt. It was the whole point. She just wished it somehow didn’t feel this...
Spank!
…this harsh! Have to find pleasure in this pain… find pleasure… this thought led Rin’s hands under herself and towards her pussy.
Spank!
Another strike made not only her ass burn, but also her pussy clench around her fingers. Rin tried to listen to her senses to tell if it hurt less now…
Spank!
Ah, no, it fucking didn’t! But yet it was still better in another way. Rin expected masturbation to let her bear the pain by distracting her form it, but what she felt was very different. The pain was still as bitter, but it also didn’t shadow the sweetness of the pleasure, and instead only made it stand out even more.
Spank!
Bad, it hurt so bad! But also good! Rin’s brain was confused between such opposite sensations mixing together, creating something new and exquisite she had never felt before. Now she started to really understand Flower…
Spank!
“Gya!” Rin squealed, as the new strike took her by surprise landing on her back. Was Len’s aim off? No, wait, he was doing in on purpose…
Spank!
…this time on her thigh.
“It fucking hurts!” Rin yelled, she wasn’t ready for this much yet!
“Didn’t know you can curse like that”, Len chuckled. “Glad you’re having fun though.”
Fun?..
Spank!
Fuck, this was… fun! Rin’s eyes started to get wet, but much wetter was her pussy. The more it hurt, the more it longed for pleasure, and Rin was happy to indulge it. Can't make an omelet without breaking eggs, right?
Spank!
“More!” Rin was surprised to hear her own voice demand. She was in more pain than ever in her life, and the only escape was through the pleasure in her nether regions. She just needed some more stimulation… some more pain to instigate the pleasure…
Spank!
And more she got! Another strike landed right on Rin’s calf, bringing her a whole new level of pain, such that she couldn’t help but squeal and squirm in… orgasm? As apparently this new height of anguish was exactly what she needed to reach the pinnacle of bliss. And so intense too! Just discovering she could cum so hard felt like all the suffering was worth it… but would she be willing to go through it again?..
Spank!
A strike on her other calf let her know nobody’s asking if she’s willing or not. Rin didn’t even cry out in pain, too confused and disoriented, as she was still not done having her orgasm. But Len wasn’t letting her just go and enjoy it, oh no.
Spank!
“W-w-wait!” Rin whined, finding it hard to catch her breath. “Enough!”
“Finally we’re getting to the most fun part”, Len grinned and once again…
Spank!
“No, really, stop!” Rin begged, as tears streamed from her eyes.
“Are you actually crying there?” Len noticed. “Let me see…”
Relieved to hear his concern, Rin obediently rolled over to her back.
“It was fun to cum so hard”, she admitted through tears. “But no more, okay?”
“Okay”, Len promised, putting the belt aside “no more spanking”.
“Thank God…” Rin sighed.
“Let’s try whipping now”, Len decided and took an... extension cord.
“What?..” Rin just blinked at her brother absently, too confused to comprehend the situation.
Crack!
A red mark appeared on Rin’s thigh, as the sharp pain felt like it was reaching all the way to the bones. For a moment Rin could only stare at it in disbelief.
Crack!
Now on her stomach. Rin instinctively held the hurt spot and curled up.
“I’m serious, stop!” she insisted. “How can you be so cruel to me?!”
“Because I love you, remember?” Len reminded. “There, can you feel it?”
Crack!
Just below her clenched knees this time. This is supposed to be his love?.. It was burning… so hot… flaming… passion?..
Crack!
No, it was too raw, too piercing! Len’s love or not, it was hurting her, it was breaking her!
Crack!
Pain, so much pain… and Len’s compassionate voice.
“You have to open up”, is what he says. “I can’t hit your front like this”.
Rin looked up at him, dumbfounded. He can’t seriously expect her to…
Crack!
On her back this time… as if it wasn’t hurt enough already. Although compared to this the belt didn’t hurt at all.
“Come on”, Len continued, “don’t you want to feel my love properly?”
Crack!
Love… she wanted Len’s love… but her arms were still desperately hugging her knees.
“I… I can’t…” Rin sobbed. “Body… won’t listen…”
“My poor sister”, Len gently caressed her cheek. “Guess we’ll have to take a break”, he said and put the cord aside.
Rin’s eyes filled with hope. Is this it, is she free now? No, Len just said a break, so he’s going to continue later… but she didn’t want to think this far ahead, for now she was happy to enjoy any moment of not being whipped. Under Len’s guidance she lied on her back and spread her arms and legs… as long as Len didn’t have the cord in his hands, she could just relax. Even if her body was aching, it was still so refreshing to not be getting new strikes. Focused on this sensation, Rin didn’t even immediately register what Len was doing with her limbs… as apparently he was tying her wrists and ankles to the corners of the bed with some rope.
“Wha… what is this for?” she asked, as if woken from a pleasant dream.
“Now you don’t have to worry about controlling your body”, Len pointed out, once again taking the cord. “The ropes will keep it in this position where my love can reach every part of it”.
“No”, Rin shook her head, “no, no, no!”
Crack! Crack! Crack!
“Let me free!” Rin was trashing violently, trying to break free, but it was only hurting her wrists and ankles. “This is not fun anymore!”
“And that’s exactly what makes it the most fun part”, Len said. “Just the way you wanted, isn’t it?”
Well, yes… or rather no… she knew she didn’t want it anymore, but not wanting it anymore was what she wanted in the first place, wasn’t it?.. Ah, she couldn’t think straight like this, under a constant onslaught of…
Crack! Crack! Crack!
“Kya-a-a-a!!!” Rin’s eyes widened. “Not my nipples, you idiot! They’re sensitive!”
“That’s exactly why I’m aiming for them”, Len explained. “Seeing how hard your nipples are, looks like at least they’re enjoying it, so why don’t you too?”
Enjoying… right…
“I can’t even reach my pussy like this”, Rin demonstrated, pulling against her restraints.
“Oh, but I can”, Len grinned.
What does he..? No, no-no-no-no-no!
Crack!
“Ki-i-i!” Rin shrieked.
Crack! Crack! Crack!
“Fuck, hurts, idiot, don’t do this, I can’t, psycho, stop, please, fuck you, I beg you…”
Crack! Crack! Crack!
“Just! Drop! Fucking! Dead!!!” Rin screamed… or more like squealed, as she was out of air and strength.
Crack! Crack! Crack!
Len continued without mercy, making sure to go all over Rin’s front body: from shins and thigs to stomach and chest, and even going up along her spread arms, only sparing her face. And of course special attention went to her nipples and pussy.
Crack! Crack! Crack!
Rin could only murmur something incomprehensible and sob bitterly. And yet…
“Just look how wet you’re getting from this”, Len was amazed.
What is he talking about… there’s no way she could…
Crack! Crack! Crack!
But she could… as much as it hurt, each strike was echoed by a very recognizable longing in her pussy… and with how Rin couldn’t do anything to satisfy it by herself, she was almost looking forward to pussy strikes, at least that was some stimulation…
Crack!
Fuck, fuck, fuck! To shit with such stimulation! Has she gone crazy to long for this? No-no, never again, please let Len never do this again! Well, maybe… no, no… but just one more time… it hurt, it hurt so much… but her pussy was begging for a loving touch… and she’d survived it this far, so it couldn’t be that bad?..
Crack!
It certainly fucking could! She’d just gone through it, how could she forget just how horrible it was and wish for it again?! But… maybe if she received more she could cum… maybe if she could cum, Len would stop… maybe if there was such a hope…
Crack!
Sob, sob… this game is so fucked up, her body is fucked up, her mind is fucked up… she wanted Len to stop, she wanted him to keep going, she needed him to keep going in order to stop…
Crack!
Burning with pain… burning with arousal… was there pleasure from pain, was there pleasure among pain, could she even distinguish pleasure form pain anymore?..
“That’s nice of you to present your pussy by yourself”, Len chuckled.
Wait, was she doing something like that? Before Rin could wrap her mind around it…
“Well, if you’re asking for it so desperately…”
Crack! Crack! Crack!
No!!! Yes!!! No more! Just a little bit more! And then she’ll be able to cum!
“Whew”, Len sighed. “That was quite a workout”.
What?
“I’m feeling hungry again after so much exercise”, Len said. “Let’s go have a lunch”.
Wait…
“Wait!” Rin had to muster her strength to speak aloud. “I was just about to cum!..”
“Are you asking me to hurt you more?” Len smirked.
“Yes? No? I don’t know…”
Rin couldn’t handle any more pain, but yet finally it felt like it was about to pay off… and now all that pain was for nothing?! If only she could at least touch herself…
“Untie me!” Rin pleaded, pulling against the ropes. “Untie me!”
“Of course I will”, Len promised, “just stop twitching”.
Rin willed herself to stay still, even if it was so hard. Her body demanded she put her hands to use right now.
“There you go”, Len said, untying her left ankle. “Now the right one…”
“Are you messing with me…”
“I do”, Len smiled. “That’s the game”.
“You… I’m so gonna kill you!” Rin roared and kicked Len off the bed with her freed feet.
“Whoa”, Len said, getting up. “Fine, just stay like this then”.
“What?..” Rin was still tied at her wrists.
“I’ll go have a lunch”, Len declared, heading out of the bedroom. “You wait here and reflect on your behavior”.
“No, wait!” Rin pleaded. “I’m hungry too… I’m… I’m sorry…”
But Len has already closed the door from the other side.

Rin was left alone. She seated herself at the top of the bed and tried to rub her thighs together, but the satisfaction didn’t come. Maybe it was too late to catch the fading arousal, or maybe it just wasn’t stimulating enough… it certainly couldn’t compare with the whipping… oh no, was she longing for torture again? Just the thought of the pain made her shudder. And yet also feel a hint of arousal. Not enough… just a thought was not enough…
Left to herself, Rin couldn’t help but catch glances of all the other torture tools Len has prepared. If just some spanking and whipping felt so harsh for her, how is she supposed to handle the rest? It was terrifying! There was no way, she simply couldn’t! But she knew that… it was because she knew she would desperately want to quit that she opted to have no such an option.
So now all she could do was just take everything Len had in store for her. No matter how much she would scream and beg for mercy, it won’t change anything. Rin was completely deprived of agency, and only her brother got to decide what would happen to her. Maybe the despair was driving her crazy, but Rin almost found this helplessness comforting. If nothing is under her control, then she doesn’t have to worry about anything. Only withstand the torture… no, she doesn’t even have to withstand it. It’s okay if she breaks. She has no safeword anyway.

The door opened and Len entered with a tray full of food. Rin’s mouth watered as she became sharply aware of how hungry she was from exhaustion. But thankfully Len has at least brought her food… right?
Len walked right past her and sat down at the computer desk.
“Mmm, so delicious”, he commented on every piece he tasted.
“Come on!” she said. “You can’t just leave me to starve!”
“Oh, do you want some too, dear sister?” Len noticed. “But food isn’t free in this world, you know, you’ll have to earn it”.
“Earn?” Rin was outraged.
Gyururu… said her stomach.
“How?” she pleaded.
“Hmm, you’re right, you’ll need your hands for that”, Len realized. “Promise not to fight?”
“I promise”, Rin said in a defeated tone. “Just let me eat…”
“Okay, here we go”, Len came up and untied Rin’s wrists.
“Ah…” Rin rubbed the painful rope marks.
“Now take these”, Len handed her a few clothespins.
“What?” Rin blinked in confusion, as she took them in her hands. “Do you want me to use them as chopsticks or what?”
“Ha-ha, that would be funny”, Len laughed. “But actually I want you to earn your food with them”.
“And what exactly do I…” suddenly Rin was hit with realization. “No… no-no, you can’t expect me to do that to myself!”
“Either you do or I do it for you”, Len explained. “But only one option earns you lunch”.
Rin wailed of desperation. If she was getting tortured either way, she should at least get some food… but how could she will her hands to do it to her own self… this was just too cruel!
“So, which will it be?” Len hurried her. “The food is getting cold”.
Fair point. There’s no good in postponing the inevitable.
“Fine”, Rin said. “I’ll do it”.
“Good girl”, Len patter her head and then returned to his meal.
Why did this praise feel so good? He just tortured her! And now wanted her to torture herself! And yet she couldn’t help but feel happy. He was till her beloved brother.
Rin took a clothespin and brought it to her nipple. Deep breath. Nervous gulp. Okay, the sooner she’ll do it, the sooner it’s over… clench!
“Uwa-a!” Rin’s eyes widened as the pain in her already whipped nipple multiplied. She had to forcefully press her hands against the bed to prevent them from taking the clothespin off right away.
Wait… if her hands are free now, she can masturbate properly, Rin realized. She put her left hand to use on her pussy… but her right hand still had to put a clothespin on her other nipple. She has already done this once, so she should be able to do it again… except now she already knew how painful this was and had absolutely no desire to suffer twice as much.
“Should I do it after all?” Len said, noticing her hesitation. “I’m always happy to help, you know”.
“Fuck you!” Rin said and clenched her other nipple. “A-a-ah, fuck me!..”
“Don’t worry, there’ll be time for that too”, Len chuckled.
“Are you happy now?..” Rin presented him the clothespins on both her nipples. “Can I eat already?”
“Nope”, Len said. “I gave you three clothespins”.
“I only have two nipples though?” Rin replied in confusion.
“Oh, but there’s another place a clothespin would fit very nicely”, Len noted. “You’re already clenching it so hard with your left thumb, surely it would feel even better with a clothespin”.
As if jolted with electricity Rin abruptly put her hand away from her clit.
“You’re kidding!” she said. “Tell me you’re kidding!”
“I’m just playing by the rules you’ve set up”, Len shrugged. “Although I’ll have to admit I’m enjoying it much more than I anticipated!”
“But you have no idea how much it HURTS!” Rin appealed.
“If you take too long, I’ll just eat everything myself”, Len pointed out.
“Grrr!..” Rin clenched her fists.
“And remember: you promised you won’t fight”, Len reminded.
“Gra-a-ah!” Rin hit the wall. “Fuck!” it hurt her knuckles.
Len was just sitting there finishing his meal. If Rin doesn’t hurry, nothing will be left for her… and then the pain she has already endured with nipples will be in vain… it was hurting badly, and she had to make it even worse, but… it was just this one last step… a big one, but it was the last… for now…
One.
Two.
“I-ya-a-a-a-a!” Rin arched her back.
She wanted to trash around, but that would just disturb the clothespins.
She wanted to just tear the clothespins off, she had to keep her hands busy.
Bang! Bang! Bang! Rin was hitting the wall again. And again.
At least the pain in her knuckles kept her distracted from the pain in her clitoris. Ah, she used to seek for pleasure to distract herself from pain, but now she resorted to using another source of pain. Another source of pain… Rin has put her thumb in her mouth along her teeth and bit on it hard. Why is she hurting herself, even without Len’s order now… she has gone totally crazy…
“Hey, don’t just start eating yourself”, Len noted. “You’ve done well, so I’ll give you some soba, alright?”
Rin raised her gaze towards Len. Yes, food, that’s what she was doing this for… she had to find strength to eat now or it was all for nothing… Rin put her thumb out of her mouth. It was bleeding. She couldn’t believe she had bitten herself that hard. But she has cast that thought aside. She had to eat.
Len pushed a pair of chopsticks and a plate of soba towards Rin.
“Oh, but you deserve better than just naked soba”, Len realized. “Here, let me add some seasoning”.
And having said so he took a knife and a couple chili peppers and started chopping them into Rin’s plate. Then made sure to mix it around so that Rin couldn’t get around it. Rin couldn’t muster her voice anymore, just staring at Len wordlessly.
“What’s wrong?” he asked. “I thought you were hungry. You don’t have to eat if you don’t want”.
Should have expected this much… Rin took some soba with her chopsticks and sent it into her mouth. It burned her mouth as she chewed. She swallowed and it burned her insides. But she had to keep eating… she had to have energy, because Len surely had a lot more torture to give her yet… sob… sob…
“There, there, don’t cry”, Len said softly.
He tenderly held her face and wiped her tears. Ah, something as simple as his loving touch was making her so happy…
Until it started burning her eyes, because he was just holding the chili pepper with these very hands.
“U-u-u-u-u!..” Rin wailed desperately. And munched down more hot soba.
Len looked at her face, all red and full of tears. How come it’s so beautiful? Normally he’d never want to put Rin in pain, he resented the idea of hurting her, she was after all his twin sister, his other half. But now that it was all just a game… even if her suffering was real, even if her begging to stop the game was earnest, all of that was the intended flow of the game. And what a fun game it turned out to be! Len was already fascinated with it yesterday when watching Miku and Flower play it, but getting to torture his own sister with his own hands was on a whole other level. Watching her break… and keeping going anyway. This was exactly what she wanted when choosing to go without a safeword, so Len was happy to provide.

After Rin finished her torturous lunch, Len had mercy and let her at least wash it down with his urine. She loved drinking his urine, of course, but Len dared not to touch his dick with his hands just yet for a proper aim, so Rin had to catch the unsteady stream with her mouth as it sprayed all over her face and body. She has almost forgotten how hurt her skin was, but the stinging in her wounds served as a reminder. Rin begged Len to at least let her take off the clothespins, seeing how the lunch she earned with them was over… if only she knew taking them off would be as painful as putting on! While they were on continuously Rin had almost gotten used to them, and now it turned out she had begged out yet new pain for herself! And there’s still a whole other half of the day left…

After the lunch Len made sure to wash his hands thoroughly before he returned to Rin.
“So, I remember you said something about fucking you?” Len said.
Rin certainly wouldn’t mind good old sex right now to make her forget all the pain, but she had a hunch that Len had something more devious in mind.
“Why don’t you stand on all fours for me?”
Still, what other choice did she have? If she fights back he’ll just tie her down and punish her harsher for breaking her promise. She made sure there was nothing she could say to stop him.
As Rin obediently positioned herself, presenting her behind to her brother, he took the rolling pin he had prepared. Wait, why the rolling pin?..
Len positioned one of the ends against Rin’s pussy and pushed in.
“Ah!” she cried, as the tip went it. “Not so harsh!”
But of course Len only went harsher, until the whole handle was inside. Then he started pushing it back and forth. Rin couldn’t help but moan in pleasure at the long awaited stimulation to her vagina, even if it was so rough like he was trying to push not just the handle, but the whole thing inside… wait… this was exactly what he was doing!
“It won’t fit!” Rin cried. “You’ll break me!”
“It’s not if it will or won’t”, Len replied. “I’ll make it fit!”
And finally he shoved the thick part through Rin’s pussy lips.
“Hu-e!” Rin exclaimed, as she felt the tip of the handle hit something inside her. “Len, stop, it has reached the end!” she implored. “It won’t go any further!”
“Nonsense”, Len replied. “Remember fisting Flower”.
“But I’m not Flower!”
“You have all the same parts”, Len continued. “So it means I’ve just reached your cervix… plenty of more space to go in your womb!”
And he continued fucking Rin with the rolling pin, the tip hitting Rin’s cervix again and again, each time opening it a little bit further.
“But it hu-u-urts inside me…” Rin wailed.
But of course that was the whole point, and so Len continued.
“Gn… ugh… gah…” Rin cried in pain, smashing the pillow with her fists, but it only encouraged Len to keep going. Until with another push the handle finally slipped through.
“Bugyaiyaiyaiya!” Rin howled.
“I guess you can call it that”, Len accepted. “Although Flower called in cervical penetration”.
“You’ve broken my insides!” Rin screamed in panic, as she pressed her hands against her belly, letting her head fall onto the pillow. “I’m going to die!”
“Well, if you think you’re dying, shouldn’t you at least try to enjoy your last moments?” Len chuckled. “Finish one last time before you’re finished?”
“It’s not a fucking joke!” Rin pleaded. “Call the ambulance!”
“Alright, how about I’ll let you call it if you can cum?” Len suggested.
“You think this is all a game?!” Rin was furious.
“But it is”, Len pointed out. “So why don’t you have fun too?”
And now he started to fuck her womb. Rin tried to protest, but soon could only utter incomprehensible noises, as she was overwhelmed with sensations from the part of her body she never contemplated existence of. Very painful and discomforting sensations. And yet… fucking exciting! She couldn’t believe she was getting off on her own destruction. As far as Rin could feel, she was torn apart from inside. And yet her pussy, the same one that was getting ravaged by a rolling pin, the same one that was suffering immeasurable pain, was at the same time basking in pleasure. Apparently, it didn’t matter if it was accompanied by excruciating agony, for the sex organs stimulation was stimulation. Such a cursed blessing! Rin hated her body for enjoying being ruined, and Rin loved it for providing at least some pleasure among all the torment.
Push… slip! The wide part has finally pushed through Rin’s cervix too, letting the handle reach the deepest wall of her womb. As it kicked the air out of Rin’s lungs, it felt almost like the rolling pin has hit her very heart. “That’s it, I’m dead…” it wasn’t even a worded thought, just a realization, and it has sent Rin over the edge. Her body shuddered in orgasm, but as her overstretched pussy tried to clench it faced with hard resistance of the rolling pin, which brought only more pain… and more fuel to the orgasm. That’s not fair, orgasms aren’t supposed to be so painful… and so powerful… Rin’s mind was going blank. “I’ve cummed…” she thought in relief, “so he’ll let me call the ambulance…” and she passed out.

Rin woke up for real when Len has bitten her clitoris. Why the hell would he do that?! Oh, yeah. The memories returned to Rin one by one. There was so much pain, so much suffering… but now that it was all in the past, Rin couldn’t help but think it was pretty fun. Just never ever again!
“Good morning, sis”, Len licked his lips. “Had fun yesterday?”
“Morning?..” Rin looked around confusedly. “Yesterday?..”
“Yup”, Len confirmed. “You’ve cummed so hard you passed out straight until morning”.
“Oh, so it’s Monday now”, Rin realized. “And I was looking forward to your turn… you deserve to feel on yourself all the horrible things you did to me!” she laughed.
“Too bad there won’t be my turn”, Len smirked.
“Yeah, I guess we can’t play this game in school”, Rin sighed.
“Why, I believe we can”, Len said. “I have plenty of ideas for that!”
“Then?..”
“You’ve never said the safeword though”, Len pointed out. “So it’s still your turn until then”.
Rin gulped nervously and clenched the bedsheet in her fists.
“But there is no safeword”, she said.
“Exactly”.
