Yuri lemons of the Raildex universe. Notes: Welcome to the first story I upload on AO3! This is a work I have great fun writing and hope to continue publishing. I hope you have fun reading it, and look forward to this and my other works! Chapter 1: Level 1: Kuroko x Misaka (part I) Chapter Text It was almost time for bed. Misaka had just finished putting on her Gekoda pajamas and was finishing brushing her teeth in the bathroom in front of the mirror. Kuroko sat on her bed thinking, still wearing her school uniform. Okay. Tonight’s the night I finally receive Onee-sama’s love. “I have to be bold and come on strong otherwise I’ll lose to that guy, To-whatever his name is!” “What was that, Kuroko?” Misaka said from the bathroom. “Ah, nothing, nothing, Onee-sama. Just waiting so I can go to bed the same time as you.” “Geez, Kuroko, you’re such a creep.” She went back to brushing. Have to be more careful. Misaka rinsed her mouth out, ready to finally go to bed. Kuroko’s heart was racing. She took a deep breath. “Hey, Onee-sama?” “Yeah, what is it, Kuroko?” Misaka said as she was getting in her bed. “I was just thinking. Are there any boys you like right now?” Misaka’s face turned bright red. “O-o-o-of course not! Wh-wh-where did that come from all of the sudden?” “Obviously there is, given that reaction. But even if there is, Onee-sama, he doesn’t know your ins and outs like I do. There’s no way he’ll be able to pleasure you like I could.” Misaka stood up, raising her fist. “Look, I already told you there’s no one like that, and just what do you mean by ‘pleasure’?” “Exactly what I said, Onee-sama.” Kuroko stood up from her bed. Misaka was about to knock Kuroko like she always does when she tries something perverted, but this time Kuroko was prepared. She dodged Misaka’s fist. A moment of silence… Kuroko lunged in and pressed her lips against a very surprised Misaka’s. Misaka felt herself grow weak in the knees. She was running out of breath due to the long kiss. All of the sudden she felt too exhausted to use her electricity on Kuroko. Kuroko finally released Misaka from the kiss. Misaka gasped for air, but Kuroko only took the chance of Misaka’s open mouth to kiss her again, this time forcing her tongue inside. Kuroko placed her hands on Misaka’s shoulders and started pushing her across the room until they both fell on Misaka’s bed. Again, Kuroko released Misaka. “Kuroko, what are you-mmmmm….” She again kissed Misaka again, determined to make her succumb. Kuroko was almost running on instinct at this point. Having experienced her dear Onee-sama’s tongue made her lose all control. She grabbed Misaka’s wrists and pinned her down on the bed, continuing to kiss her with tongue relentlessly. Misaka began to lose her strength. Kuroko is too strong. I can’t resist her. She clearly prepared for this tonight. I’m losing my strength. I’m feeling fuzzy, but….I’m surprised. Kuroko’s lips are softer than I expected and her tongue feels warm and comforting. What is this strange feeling? Ahh~, I feel really weird. Kuroko thought it was time to finally advance to the next step. She let go of one of Misaka’s wrists, the one she was holding with her left hand. Surprisingly, Misaka didn’t do anything. She was too dazed to move. Kuroko took this opportunity to slide her left hand into Misaka’s pajama pants, rubbing her index and middle finger across Misaka’s panties over her sensitive spot. Misaka let out a near silent gasp and her breathing became heavy. “Oh, my.” Kuroko said with surprise. “You’re really wet down here, Onee-sama.” Huh? What is Kuroko saying? Thought Misaka. I’m too dazed to hear her words clearly. I’m …‘wet’ somewhere? Kuroko tried to hold back. Gotta save that for later she thought. Kuroko let go of Misaka’s other wrist and removed her other hand from within her pants. She unbuttoned Misaka’s Gekoda pajama shirt. Her heart was pounding like crazy. She slid down a little so her face was even with her dear Onee-sama’s stomach. She began kissing and licking it. She slowly caressed Misaka’s body with her tongue. Ahh~, Kuroko feels so warm on top of me. Actually…..it…..doesn’t feel all that bad. Kuroko had made it to Misaka’s chest by now. She licked her left nipple and used her fingers to play with her right one. Misaka let out a whimper. Kuroko switched, this time licking her right nipple while playing with her left. Misaka continued to whimper, as if she was on the brink of orgasm. Kuroko moved on to start attacking Misaka’s neck, licking it relentlessly. Kuroko could hear Misaka’s breathless gasps and heavy breathing. She was beginning to pant. Kuroko brought her face close to Misaka’s. Both their hearts were now racing. This time, Misaka leaned in and closed her eyes, awaiting the taste of Kuroko’s lips. Kuroko leaned in and kissed Misaka on the lips, again, using her tongue. Maybe…I’ll do it too. thought Misaka. She then slid her tongue into Kuroko’s mouth. Kuroko started to moan at the feeling. I….didn’t know Kuroko could make that sound before. It…..sounds cute. I…..want to hear more of her. And the two battled it out with their tongues for supremacy. With Misaka caught up in the kissing, Kuroko decided it was finally time to get back to the final moves to get Misaka to cave in to her love once and for all. Again, Kuroko slid her hand into Misaka’s pants, rubbing her fingers over Misaka’s panties. Misaka pulled away from the kiss. Not being able to hold it in, she broke away from the kiss to gasp. I feel kinda funny. My body……feels really hot. Kuroko then slid her hands into Misaka’s panties, rubbing her fingers over Misaka’s slit. “Wow, now you’re really wet down here, Onee-sama.” “Huh? I’m w-“ She didn’t even finish asking before Kuroko inserted her two fingers inside Misaka’s slit. “Ahh~ Kuroko, what are you doi-ahh~” Misaka’s hips started to thrust…My body is moving on its own. Misaka was really on the brink now. Kuroko thought it was time to initiate the final blow. Kuroko got up off the bed and kneeled down, knees on the floor, next to the bed. Misaka finally rose up now that Kuroko was off her. “Kuroko?” asked Misaka concerned. “What is it, Onee-sama? Afraid I’m going to stop?” Kuroko asked in a teasing manner. Misaka’s face turned bright red in a surprised look and she turned away embarrassed. “Hehe, don’t you worry, Onee-sama. I’m going to finish you up right now.” “Huh? ‘Finish’ me up?” Misaka had no time to ask before Kuroko grabbed Misaka’s pajama pants and gently pulled them off. Kuroko then took off Misaka’s panties as well. “Hold on, Kuroko. What are you doing, here?” Kuroko didn’t say anything. She forced open Misaka’s weakened knees and slowly leaned inside. “Kuroko, what are you-mmpf!?” Kuroko had already entered her tongue into Misaka’s slit. “Ahhh! OH, GOD!” Misaka had cried out. She gripped the bed sheets with both hands so hard her knuckles were pale as snow. Misaka quivered at the pleasure. Kuroko’s really good at this. Wait-What am I saying? How is Kuroko doing this to me? Ahh, my thoughts are all messed up because of her! But….am I really okay with this? I’m not exactly stopping her. Does that mean….I like this? My body feels like it’s going to melt. Kuroko’s tongue is so soft and warm. Ah~ It feels really good. I never knew Kuroko of all people could make me feel this way. Kuroko stopped for a second and looked up at Misaka. “Oh, wow, Onee-sama. You must really like this. You’re making such a lewd face, and you’re drooling too!” “Huh?” Misaka blushed with an embarrassed look. “Kuroko I-I think-“ “Shh.” Kuroko hushed. Without a word, she put two fingers on Misaka’s lips to quiet her, as if she didn’t need to hear it. She wiped the drool from Misaka’s face with her fingers and sucked on them. She slowly licked her two fingers, getting all the taste of Misaka’s oral fluids. After licking her lips in satisfaction she leaned back into Misaka’s legs and slid her two fingers inside, pulling them in and out, finger-banging Misaka. She then proceeded to lick up and down Misaka’s slit while fucking her with her fingers. “OH, KUROKOOOOO~” Ahh, something’s happening inside me. Something’s overflowing. It’s going to flood. I can’t hold back much longer! Misaka, still sitting up, let go of the bed sheets, and weaved her hands through Kuroko’s hair. She undid her twin tails and threw the ribbons tying them on the floor. She grabbed onto Kuroko’s now untied, let down hair. She was crying out, having orgasm after orgasm. Ahh, it’s coming. I-I can’t hold it in anymore. Kuroko stopped fucking her and leaned back for a second. Fluids went spraying all over her face as Misaka let out a piercing cry. She looked down at Kuroko, embarrassed at what she had done to her. Kuroko simply smiled, and licked her lips as if she had just eaten a delicious meal. She wiped the fluids off her face with her fingers and began sucking on them, savoring every taste. “Wow, Onee-sama. You came so much.” Huh? Kuroko actually……..made me cum? “Well, that’s only because you were fucking me so hard. More importantly, how are we going to explain the loud cry I let out just now?” “Quickly, Onee-sama. Put your pajamas back on.” They could hear footsteps. Finally, a knock on the door. “Is everything alright in there?” asked one of the maids at the dorm complex. “Yes, ma’am.” I just thought I saw a spider. It was only my imagination. Everything’s fine.” “Okay, then. I’ll let the others know so there isn’t any panic about. Goodnight, girls.” “Oh, goodnight.” Misaka and Kuroko said in unison. Both let out a huge sigh of relief. Misaka crawled into her bed, thinking about what just happened while Kuroko went to put on her pajamas. Misaka turned her head to see Kuroko crawling into her bed as well. Surprising to Kuroko, she didn’t hit her out of the bed. “Hey, Onee-sama? Is it okay if I sleep in your bed with you tonight?” “Sure.” Said Misaka. She then blushed and turned away. “And call me Misaka from now on.” Kuroko was in shock for a second. She chuckled a little. “What’s so funny, Kuroko?” asked Misaka. “Oh, nothing, Misaka-oneesama.” And the two drifted off to sleep. Chapter 2: Level 2: Misaka x Kuroko (part II) Chapter Text It was morning. Misaka had woken up. It was Saturday, so there was no school. Kuroko had gone out early to do some Judgment work so Misaka was alone in the bed. She had suddenly remembered what had happened the night before. Her face turned bright red. She put her fist to her face, as if she was confused for some reason. Did that really happen last night? Did Kuroko really pleasure me to the point of climax? I was kind of dazed during the time so it’s a little fuzzy, but I remember the main details. Ahh, can’t think about this right now. Kuroko must be doing work for Judgment today if she’s not here on a Saturday. She’d never tell me because she doesn’t like it when I tag along. Guess I’ll just enjoy myself now that she’s gone for the day. Think I’ll go to the bath house. Misaka had gotten dressed in her uniform and got ready to head out. She was happily humming to herself along the way, eager to get to the baths to relieve stress. When she arrived, she had found she was the only one there to take a bath.The woman working there had said there were no other customers. Misaka then happily stripped in the changing room and got in one of the bigger baths. Ahh, this is great thought Misaka. “Hey, Miss! I’m heading out on break, so you’ll be here alone for a bit. You already paid so you can leave before I get back if you want!” “Okay, thanks!” Wow, I really have the place to myself! Misaka tried to relax, but for some reason, images of Kuroko entered her mind, bringing her back to last night. Ugh. Why does she keep entering my mind? I can’t stop thinking about her! Why is my heart pounding so hard right now? And why do I feel so hot? It must be the bath doing this. I still have a hard time believing it. Did Kuroko REALLY do those things to me? Misaka took her two fingers on her right hand and put them in between her legs. I mean, she did THIS to me! Misaka started tracing her fingers across her slit in the water. She closed her eyes and re-imagined what Kuroko was doing when she had done it to her. Ahh~ It feels good. But it doesn’t feel as good as when Kuroko was doing this to me for some reason. Misaka started gasping and panting. She lifted her left hand and started massaging her right nipple. Ahh~ It’s happening again. That overwhelming flooding feeling. Her hips made a large thrust forward and her back arched inward as she let it all out with a scream. It happened again. It’s a good thing no one heard me nor saw me. I think I would die if I got caught doing such a lewd thing. Still, I wonder why I started doing it when I started thinking of Kuroko. Was all this….really just the hot water? Misaka got out of the water, dried off, put her clothes back on, and started heading back to her dorm room. As Misaka opened the door she saw Kuroko resting on her bed. “Oh. Hey, Onee-sama. Where were you until now?” Misaka’s face turned bright red and she got an embarrassed look while remembering what she did and what she had thought while doing it at the bath house. She gulped. Her voice was shaky. “Oh, just at the bath house. I wanted some time to relax since I was alone.” She quickly wanted to change the subject. “So, how was Judgment work today?” “Oh, not much, really. One robber and he didn’t even have a serious weapon on him.” “Well, if you didn’t have much to do, then why were you on the bed moping looking tired?” “I was waiting for you to get back, Onee-sama. I was SO bored without you!” Misaka tensed up as she blushed. “Say, Kuroko?” “What is it, Onee-sama?” “Ho-How would you feel if I gave you a reward for today? F-F-F-For putting up with all this today. Think of it like an apology gift.” Kuroko’s face lit up all of the sudden. “Wow! Do you really mean it, Onee-sama?” Kuroko perked up and sat up on the edge of the side of the bed, kicking her legs in anticipation and excitement. She patted the bed with her hand, signaling for Misaka to join her. Misaka sat down, put both hands on the bed and leaned in so her face was really close to Kuroko’s. Her heart was beating so hard one could almost hear it. “Just….tell me what to do.” Said Misaka. Kuroko was a bit taken back by the arousal. She didn’t expect Misaka to be so honest with it. Kuroko blushed. “O-Okay.” She murmured. “How about you kiss me to start things out?” Misaka gulped. She lifted her hand and put it on Kuroko’s shoulder, leaned in and pressed her lips on Kuroko’s. Misaka slipped her tongue inside. She closed her eyes and just let the warmth of Kuroko’s tongue comfort her. It feels like Kuroko’s tongue is warming up my whole body. It’s so hot, and my head is starting to grow dizzy again. Misaka finally released Kuroko, who seemed to be in a daze. As Misaka opened her eyes slowly, she couldn’t help but tense up at the sight of Kuroko so close to her. “Okay.” said Misaka in a timid voice. “Now what?” “Massage and play with my breasts.” Kuroko said looking embarrassed. Misaka’s heart started to race as she removed Kuroko’s vest and started unbuttoning her shirt. After she unbuttoned Koroko’s shirt, she slid her hands up Kuroko’s body until she reached her breasts. Misaka started massaging them as Kuroko let out a bunch a cute noises. Misaka leaned in and sucked the left one. Kuroko let out a loud gasp. Kuroko sounds so cute. I want to keep hearing her. Misaka continued to suck and lick both of Kuroko’s nipples, alternating between the two while groping her breasts. Kuroko continued to make noises. Misaka stopped to breath for a second. “Oh, Onee-sama, I can’t wait anymore. Fuck me, please!” Kuroko begged. Misaka’s head started to spin at the thought. “Okay.” She muttered in a shy voice. She removed Kuroko’s shorts and panties and laid her down on the bed. Misaka laid next to her and moved her hand down to Kuroko’s sensitive area and traced over it for a while before inserting her two middle fingers inside. “Wow, Kuroko. You’re really wet down there. You must’ve wanted this really bad.” Kuroko tried to hold in all her moaning to muster a few words. “That’s because……. it’s you doing it…, Onee-sama.” Misaka glanced at Kuroko’s face and blushed. Kuroko continued to orgasm relentlessly. Her hips began to thrust and her back arched upward. “It’s no use. It’s coming, Onee-sama. I can’t hold it in anymore. It’s going to flood. I’m going crazy. It feels so good!” Kuroko let out a cry as her juices came flooding out. Misaka removed her fingers and sucked on them, licking them clean. “Wow, Kuroko. You sure came a lot.” Kuroko got an embarrassed look for a change as her face turned a really bright red. “Well, that’s only because you were fucking me so hard.” The two of them closed their eyes, leaned in and kissed passionately like they were in their own world. “I’m sorry, Kuroko.” Said Misaka as they opened their eyes. “I wanted to give you a reward and make you feel good, but I want to feel good as well. I’m being selfish. Would you please……make me feel good too?” “Sure Onee-sama.” Kuroko said in a soft voice. “You’ve given me plenty of a reward already. So I guess it’s my turn to make you feel good again.” Misaka definitely couldn’t deny it anymore. Kuroko had made her feel really good the night before. They both sat up and Kuroko had removed Misaka’s vest. Misaka’s heart began to pound as Kuroko began unbuttoning her shirt. They kissed again. Kuroko began to move her tongue down and licked Misaka’s neck. Misaka began to whimper. Kuroko had finally finished unbuttoning Misaka’s shirt and dropped it onto the floor. Kuroko started to kiss and suck on Misaka’s breasts. Misaka began to pant as she began to get lost in the pleasure. Kuroko really is good at this. It feels so good I’m going crazy. Kuroko gently laid Misaka on the bed and repositioned herself so her face was between Misaka’s legs. She took off Misaka’s skirt and shorts. “Oh, my. Onee-sama, you’re panties are really wet. Did you really want this that badly?” Misaka just looked away in embarrassment. “Heh heh. Don’t you worry, Onee-sama. I, Kuroko will do my very best to serve your needs!” Kuroko began to trace her finger across the fabric of Misaka’s panties and she noticed that the fabric was getting wetter and wetter. Kuroko put her tongue on her panties and began to lick them. Misaka started to orgasm. “Oh, Kuroko. Please don’t tease me. Please, fuck me!” Misaka had quickly covered her mouth in embarrassment with wide eyes, surprised at the lewd thing she had just screamed at Kuroko. Kuroko snickered. “Wow, Onee-sama. I figured you wanted it, but to be this desperate to be relieved…Don’t you worry. I’ll take good care of you.” Kuroko had removed the sopping panties from Misaka and tossed them on the floor. She leaned her head in and started sucking on Misaka’s sensitive lower lips. Misaka began to let out relentless moaning and gasps. After a while Kuroko pulled her head out and licked her lips in satisfaction. She then crossed her fingers and slowly placed them inside her slit, sliding them in and out continuously. Misaka was nearly crying. She gripped the bed sheets with amazing force and bit her lip to restrain herself from screaming at the top of her lungs. Wow. My fingers are sliding in and out so easily. Onee-sama really was begging for this, which means my attempt to get her to understand my love was a success. Alright, Onee-sama. I’ll make you feel really good to show you how worth it my plan was. Kuroko, still sliding her crossed fingers in and out of Misaka’s pussy, leaned her face in again and started alternating between sucking on her sensitive area and licking her slit. Ahh~ It feels so good. Kuroko’s fingers are sliding in and out of my pussy and rubbing inside me. Her warm tongue is gliding across my slit. Misaka gasped. “Ahh~ Kurokooooo! It’s coming. Just like last time. It’s….It’s going to flood. It’s going to come out!” Kuroko stopped what she was doing and slid up. She grabbed Misaka’s face and kissed her with their mouths open so Misaka’s scream would be quieted. She let it all out but the kiss kept it at a lower volume. Kuroko released Misaka from the kiss. Both of them were panting heavily. They seemed to relax for the moment. Misaka turned her head so she and Kuroko were facing each other. Misaka smiled. “You were amazing, Kuroko! I came so much thanks to you.” She leaned in and kissed Kuroko again. Kuroko became flustered. She looked away, embarrassed. “Oh, no, Onee-sama. The pleasure is all mine. You made ME feel really good.” Misaka’s face turned red at the compliment. “W-Well, I think it’s about time for lunch. But first we should clean ourselves, don’t you think?” “Yeah, you’re right. Say, Onee-sama?” “Yeah, what is it, Kuroko?” “Do you think maybe….we could go for lunch together?” Misaka blushed, and then smiled. “Sure. Why not?” Kuroko wrapped her arms around Misaka. “Oh, thank you, Onee-sama!” Kuroko got out of the bed and began to get dressed. “Well, I’m off for a while.” “Huh?” Asked Misaka confused. “Aren’t you going to clean yourself off in the shower?” “Oh, I’m going somewhere else to clean myself.” “Where are you going?” A big smile lit up Kuroko’s face. “….To the bath house…..” Chapter 3: Level 3: Konori x Kuroko Notes: This chapter takes place during the beginning of chapter 2 when Kuroko woke up the next day and Misaka heads to the baths. Chapter Text Level 3: Konori x Kuroko It was Saturday morning and Kuroko had just woken up. She found herself in Misaka’s bed, remembering what had happened the night before. Oh, yeah. That’s right. I was able to seduce Onee-sama and we ended up sleeping in the same bed. Kuroko turned her head and saw Misaka’s sleeping face. She grew embarrassed for a second. I have Judgment work today, so I might as well leave while Onee-sama is still sleeping. She can’t be coming along with me. Judgment is MY work. She quietly got out of Misaka’s bed without her noticing. She got ready for the day and head out to do work with Judgment. When she arrived, Uiharu and Konori were waiting in their usual spots. Konori was leaning over Uiharu’s shoulders, looking at her computer monitor. They both turned their heads to see Kuroko arrive. “Oh. Welcome, Kuroko. We’re working on a case of an escaped convict. He escaped custody and is on the run. Uiharu is tracking him down right now.” Kuroko looked over Uiharu’s shoulders along with Konori. “Alright!” exclaimed Kuroko. “We should get a move on this guy before he gets too far away from custody. Where is he?” “Looks like he’s heading down this street right here.” said Uiharu as she pointed to a road on the screen. “Alright!” exclaimed Kuroko. She nearly jumped up in excitement. She turned around and started dashing out. “Let’s go, already!” Konori let out a sigh. “Can’t be helped.” She started walking out after Kuroko. “We’ll be back in a little bit, Uiharu.” She then turned back around and headed out the door after Kuroko. Saten barged into the room with a loud voice. “U-I-HA-RUUU!!” Uiharu blushed with an embarrassed look. Her heart started to race. “Oh, hey, Saten. What’s going on?” Saten sat down in a chair nearby. “Oh, nothing. I’m sooooo bored!” Uiharu thought of an idea. “Well, Konori and Kuroko just headed out to catch a robber downtown. They shouldn’t need me for a while. Wanna go somewhere else in town and get something to drink?” Saten jumped up in excitement. “Yeah! That sounds perfect! It’s really hot today.” Uiharu smiled. “Great.” she said “Let’s go, then.” Meanwhile, at the crime scene… “That’s the last time you rob a bank, Mister!” Kuroko could be seen kneeling on this man’s back holding one of his arms and cuffing him as Konori raised her hand to her head and sighed in disappointment. She remembered the destruction of the city that had just occurred as Kuroko needlessly destroyed everything in her path to catch the criminal. Kuroko seems so restless today. I wonder what’s eating at her. In any case, let’s just hand over the criminal to Judgment and be done with it. “Alright, Kuroko. Let’s wrap up here so we can be done with the day.” Kuroko was finishing handing over the criminal. “Yeah, sure! Let’s head back to headquarters so I can turn it for the day and tell Uiharu I’m leaving!” I can’t wait to get back to our dorm room so I can see Onee-sama, especially after what we did last night. I wonder what she’s doing now. It would be hilarious if Onee-sama was pleasuring herself to me right now. That would be the ultimate victory! Kuroko let out a perverted laugh. But that’s probably not happening right now. Kuroko and Konori arrived back at Judgment HQ. “There’s no one here.” remarked Konori. They walked a little to Uiharu’s desk and saw a note: “I have gone out with Saten, but NOT on a date. Just as friends! I wouldn’t be back until you’ve gone, so you can leave when whatever. -Uiharu” Konori smiled with a somewhat troubled look. I wonder why she would think we would assume she was on a ‘date’ with Saten… “Well, in any case, we’re set. But before we go, Kuroko, why have you been so anxious lately? What’s been eating at you?” Kuroko twitched a little. She looked away. “Well, nothing really.” Konori leaned in really close to Kuroko. Their faces were almost touching. “Stop lying. What is it? I need to know so we can fix it and get you clear headed again. You’ve been acting weird all day and you destroyed about half the city because of it. It can’t happen again. “ “Well, to be honest…I….I….had s-s-sex with Onee-sama last night! But, well, all that really happened is that I pleasured her. Nothing else beyond that happened.” “I see. You’re sexually frustrated because you pleasured Misaka, but she did not reciprocate, is that correct?” “Well, when you put it like that, I guess so.” “So you just need to be pleasured, then. Let’s hurry and fix that while it’s just the two of us right now.” “HUH?” Before Kuroko could say anything more, Konori leaned in kissed Kuroko, whose eyes widened. Konori didn’t hold back. She forced her tongue into Kuroko’s lips and began dominating her. She grabbed on to Kuroko’s shoulders to hold her still. Kuroko tried to escape but Konori had overpowered her. Konori started walking, pushing Kuroko until she was up against the nearest wall, their lips still together. Still kissing Kuroko, Konori lifted one hand from Kuroko’s shoulder and slowly started moving down her body, sliding down her stomach. She slid her hand into her skirt. She finally released Kuroko, who gasped for air with a moan. Konori started moving her fingers inside Kuroko’s skirt. Kuroko couldn’t help but start to moan. She hadn’t been pleasured like this before. Usually it was her doing the pleasuring. She began to grow weak in the knees. She started trembling. She began panting at the sensation of Konori’s fingers moving around in her skirt. I can’t believe Konori is doing this to me. I want to tell her to stop but it feels really good. No, wait! I have Onee-sama. I’m not going to let her get to me. But this feels too good. I’m beginning to….lose myself. Konori lifter her hand from Kuroko’s skirt and began playing with her breasts with it. Kuroko could feel her mind going blank now. Konori stopped for a second. She reached and grabbed one of Kuroko’s hands. She gave a light tug and led Kuroko to one of the nearby computer chairs and sat her down. Kuroko was in a daze, looking stunned at the still calm Konori. Konori leaned into Kuroko’s ear. “Don’t worry. I’ll take good care of you so we can get this problem of yours fixed.” She then lowered her head a little and began licking Kuroko’s neck. She quivered at the sensation of Konori’s soft, moist tongue and hot breath. Kuroko was too taken aback to even move at this point. Her body had become so numb that Konori was doing most of the work. Konori removed Kuroko’s vest and undershirt. She leaned back in to lick and nibble on Kuroko’s ear as she undid her bra. She tossed the clothes onto the floor. She moved her head down a little and began licking and sucking on Kuroko’s right nipple. Kuroko put her hand over her embarrassed looking face as if she was trying to cover her moans of satisfaction. Konori moved on to the left nipple next. Kuroko couldn’t hold herself back much longer. She was starting to gasp more frequently. This is just to relieve my frustration Kuroko thought. There’s nothing behind this. She relented. She looked down at Konori, who stopped licking and sucking for a second to look up at Kuroko. They were both blushing. Kuroko put her hand softly on Konori’s cheek. “Please. Make me feel good, Konori.” Konori reached up her hand to Kuroko’s blushing cheek. “Don’t worry. I’ll take care of everything.” And they leaned in and share a deep kiss. Kuroko just relaxed and let Konori dominate her. Even Kuroko’s legs had started to writhe from the feeling of Konori’s tongue inside her mouth. Both of them started moaning at the feeling. They continued to kiss passionately, Konori still being dominant, for a few minutes before they both let go and gently pulled away. Konori slowly slid her hand into Kuroko’s skirt, rubbing her fingers against the fabric of Kuroko’s panties. Kuroko’s breath started to get heavy. She started panting. I won’t be able to face Onee-sama after this. But….it feels so good, like my body is going to melt. Konori could feel the panties she was rubbing getting wetter and wetter. “It looks like you’re enjoying this. That’s good to know. You’ll be feeling better in no time.” Inside Kuroko’s skirt, Konori’s fingers slid underneath the fabric of the soaking panties and clawed their way into Kuroko’s body. “Ahhhhhhh~” Kuroko continued to let cute sounds escape her lips. Konori’s fingers began to make a clawing motion inside Kuroko, as if she was hitting all of Kuroko’s inner sensitive spots one after another. Kuroko was beginning to get dizzier and dizzier. She felt her legs shake and her body get jittery. Konori lifted her hand out of Kuroko’s skirt and put her fingers into Kuroko’s openly hanging mouth. Kuroko all but managed to move her tongue around Konori’s fingers to savor all the juices. Kuroko couldn’t take it anymore. She needed to be relieved soon to release all the sexual frustration built inside her. Kuroko, still dazed and blushing, put her arms around Konori’s neck and pilled her in a little. “Please, Konori. I’m so hot down there. Make it feel better.” Konori nodded. She gently lifted Kuroko’s hands from her neck, kissing them as she let them down to Kuroko’s side. She unzipped Kuroko’s skirt and pulled it off and set it down on the floor beside the chair, subsequently pulling off her panties. Konori softly opened up Kuroko’s legs and leaned inside. She began gliding her tongue up and down Kuroko’s vaginal lips. Kuroko shuddered at the feeling. Konori took two fingers and slowly inserted them inside, still gliding her soft tongue over Kuroko’s sensitive area. Kuroko grabbed on to the arms of the chair with an iron grip and arched her back as if it was aching. She managed to restrain herself a little. “Konori….If….you keep doing that…..I’ll…….Ahh~” Konori continued her luscious assault on Kuroko’s most sensitive place. It’s alright, Kuroko. You can cum. Once you do, you’ll feel better. Kuroko was losing her mind, having a long, deep, escaping orgasm. “It’s….it’s coming! I’m going to……..AHHHHHHHHHHH~” Kuroko let out a loud yet soft cry as she let it all come flowing out. Konori removed her fingers and pulled away from Kuroko’s legs. She licked away Kuroko’s sweet fluids from her lips and fingers. She positioned herself back to being face to face with Kuroko and they kissed again for a few more minutes, this time, both their tongues fought it out for supremacy. They gently pulled away again as a glistening line of saliva connected their tongues. “Well, that should just about do it.” said Konori. Kuroko still seemed dazed for a second. She shook her head a little and came back to her senses. “Uh….yeah. That should do it, I guess. Well, I’m heading out now.” Things are going to feel really awkward in front of Onee-sama now. “Konori, I’m heading back to my dorm at School now. See you around….” She blushed and headed out of Judgment HQ. On the way back Kuroko thought Speaking of Onee-sama, I wonder what she’s doing now. It would be absolutely lovely if she was thinking about me. I know Onee-sama, though. She probably went to the bath house. I can’t wait to see her! Konori was good, I’ll admit that, but I bet Onee-sama will be so very much better. She raised her hand to her mouth and snickered all the way back. Chapter 4: Level 4: Uiharu x Saten Chapter Text Level 4: Uiharu x Saten “Yeah, so I wanted to talk more about what we have to do on this next case.” said Uiharu over the phone to Kuroko. “Yeah, yeah. Okay.” Said Kuroko back. “Where should we meet?” “How about that drink place I really like?” “Okay. Sounds good. I’ll meet you there in an hour” Kuroko confirmed. One hour later… Uiharu had called Kuroko in order to discuss a case the two of them were working on for Judgment. Kuroko, though ready to discuss the case, had something else she wanted to discuss… “So, let’s get down to business” said Uiharu. The two had arrived to a little place that offers drinks and the two sat outside at one of the tables for two, a little away from the restaurant, at the end of the property, where they could talk in private. … “So that’s the plan, then” confirmed Kuroko.” “Yup. That should be it” reaffirmed Uiharu. “So, then, Uiharu. I want to ask you something else” said Kuroko. “What’s that?” asked Uiharu “Do you like Saten?” Uiharu immediately spit out her drink and coughed a little “O-O-Of course” remarked Uiharu waving her hand frantically. She’s my best friend!” “Not like that” said Kuroko. “I mean, do you have a crush on her?” “N-N-N-No way! Like I said she’s my best friend!” “But you’re blushing, though” pointed out Kuroko. “I said it’s not like that! She’s always pushing me around and flipping up my skirt. There’s no way I could like someone…….like…….” Uiharu’s voice got softer and softer as she spoke the line. She wobbled a bit in her chair before fainting and falling out of her chair. “Uiharu!” Kuroko quickly went to her and touched her forehead with her palm. “Oh, no. She has a slight fever! I should get her to bed.” Kuroko brought her to her dorm room Tokiwadai. Misaka happened to be absent from the dorm room. Kuroko went in with Uiharu and rested her in bed, not bothering to changer her out of her school uniform, with the blanket over her. “I should probably-“ She paused. “Wait. Even better…” She started snickering. She pulled out her phone and dialed Saten’s number… … “Hey, Saten. It’s me, Kuroko. Can I ask you something?” “Yeah, sure, I guess” Saten answered. “Do you like Uiharu?” “Uh, sure, I guess. She is my best friend, after all.” “No, no” Kuroko corrected. “I mean, are you like, in love with her?” “Huh? Well, I don’t think so. I never thought about it. I just went along with our friendship. Anyway, is that all?” “Oh, no. Uiharu is a little sick and needs someone to take care of her. I can’t so I thought I would ask you.” “Uh…” Saten nearly shouted over the phone. “Don’t you think that’s a little more important than that question?!” “Well, I just thought I would ask. So, can you come over to my place? We were closer to Tokiwadai so I brought her to my and Onee-sama’s dorm.” Saten put her free hand on her face and sighed. “Yeah. I’ll be right over.” A few minutes later… “I’m here, Kuroko. You can leave now.” Saten looked around. Kuroko was nowhere to be found. “Why that little- Anyway, better check on Uiharu. Uiharu was sleeping in Kuroko’s bed, but panting and sweating. “I should probably do something about her high temperature.” She went into the bathroom and grabbed a small cloth and rinsed it in cool water. She walked back to Uiharu and placed it on her forehead. Uiharu’s breathing calmed down a little. I should probably leave her for a few minutes and check back later. But I shouldn’t leave the dorm entirely. Think I’ll use their bathroom to take a bath. I’ll check on her when I’m done. Saten changed out of her clothes and prepared a bath for herself. As she was in the tub, she thought to herself…Ah, this is nice. I wonder, though. Why did Kuroko ask me that weird question before asking me to come here? I don’t ‘like’ Uiharu, do I? She closed her eyes and envisioned the times she flipped up Uiharu’s skirt. Haha. She’s always so cute when I do that. Uiharu seemed to take over Saten’s mind. I’m thinking about her so much. Maybe I do like her? Saten moved her hand and put two fingers in between her legs. She began tracing her fingers across her vaginal lips. Ahh~ What’s this strange feeling I’m getting? I’m starting to feel hot. “U…..i….ha….ru.” She inserted her middle finger inside. “Ahh~ I feel something in between my legs.” Saten began panting. She inserted her index finger next, and began pumping her two fingers in and out slowly. “Uiharu.” Her legs began to tremble. “Oh, no. Something’s coming. I’m……gonna cum. I’m gonna cum while calling out Uiharu’s name. Ahh~ Nyaa~ Uiharu. Uiha-ha-ha-haaaaa-aaaaaahhhhhh~” Saten’s back arched inward. She quickly opened her eyes and covered her mouth with her other hand, in hopes that Uiharu had not been awoken. When Saten heard only silence, she let go and breathed a sigh of relief. She removed the fingers in her vaginal lips and brought them close to her face. She stared at them for a second. What…..was that? I…..just came while calling out Uiharu’s name, right? So…does that mean I like her that way after all? After finishing up her bath, Saten put her uniform back on. Okay, that was awkward. I should check up on her now…Saten looked over. She saw that Uiharu was still sleeping, but now her face was calm and she was sound, resting peacefully. Oh, good. She must not have heard me. She breathed another sigh of relief. She walked up to Kuroko’s bed where Uiharu was sleeping. She looked down a little at her. You know, now that I think about it, Uiharu really is cute. She got on her knees so she was even with the bed. She leaned over her. Wow. I never noticed this. Uiharu’s lips look so soft and pink. She moved in closer. I want to….Sorry, Uiharu…Saten moved her hair back with one hand and moved in so her face was hovering over Uiharu’s. Her heart began to pound harder and harder. She finally leaned in just a bit more and placed her lips onto Uiharu’s. Saten began to moan. Mmmm. Uiharu’s lips taste really good. Oh, no. I can’t stop. Uiharu started to let out a few moans herself. She was beginning to wake up. However, Saten was unaware. Uiharu slowly opened her eyes to the sight of Saten with their lips pressed against each other. Uiharu’s eyes slowly widened until they couldn’t be opened any more. It was now that Saten just let her lips off of Uiharu and turned her face slightly to see her with her wide eyes. There was a second of awkward silence. Saten’s eyes then widened as well and grew read as a tomato. Saten began to ramble about it being some kind of misunderstanding while Uiharu just touched a finger to her lips and thought. So that sensation on my lips just now was actually…Uiharu sat up while Saten continued to ramble. The cloth fell off her forehead. Uiharu just stared at Saten, who was still rambling while looking off in every direction trying to avoid eye contact. After a second, without a word, Uiharu just leaned out a little bit, gently grabbed Saten’s cheeks, pulled her in, and kissed her. Saten just stopped and let it happen. She understood Uiharu’s thoughts. She knew Uiharu had been having those thoughts too. When they pulled apart, both were still blushing. Uiharu reached for one of Saten’s hands and gently led her over to the bed, so she was now lying on top of her, Uiharu back to laying down. Both of their hearts started racing. They stared into each other’s eyes for a second. Saten moved the blanket over to the side so Uiharu was no longer under it. Saten gently tugged at Uiharu’s neckerchief on her uniform, loosening it. After dropping it on the floor, she brought Uiharu back up to a sitting position on the bed so they were both sitting on the bed. Saten then removed the top of Uiharu’s uniform and dropped that on the floor as well. Saten slowly leaned in, embracing Uiharu, placing her hands on Uiharu’s upper back. “Are you sure?” Saten whispered. She could feel Uiharu nod her head, and with that Saten undid Uiharu’s bra and let that go to the floor as well. Saten then put her hands on Uiharu’s shoulders when they kissed. This time it was a long, deep kiss. Their tongues rolled over each other’s, tasting each other’s lips as well. As they pulled away, Saten moved down and began licking Uiharu’s neck, who began writing at the sensation, trying to keep her lewd noises in. She then moved lower to Uiharu’s exposed breasts, rolling her tongue around her left nipple, and using her fingers to play with the right. This time, Uiharu could not help but gasp at the feeling. Holding in all her feelings of pleasure caused them to all come out at once when she could hold on no longer. Uiharu’s mouth hung open. It was one gasp after another. She began drooling. Saten moved the hand she was using to play with Uiharu’s right breast down to her skirt and slid it inside, rubbing her fingers against the wet fabric of Uiharu’s panties. The gasps escaping Uiharu’s mouth had turned to full orgasms at this point. Saten stopped licking Uiharu’s nipple and moved her face to Uiharu’s ear. “Your panties are drenched” she whispered. Uiharu tried to get her response out as clearly as possible between the orgasms she was having. “W-W- Well, that’s….ahh….only because you’re…ahh…..making me feel so g-g-good.” “I’ll make you feel even better now” Saten said in a soft voice. Saten stopped what she was doing and got out of the bed. She gently pulled on Uiharu’s arm to lead her out as well. Saten squatted down and pulled down Uiharu’s skirt to the floor. “Wow. Your panties are really soaking now. You must have really wanted this.” Uiharu just turned away in embarrassment. Saten stood back up. She placed her hands on Uiharu’s cheeks, turned her face back and kissed her. Saten was dominant. She slid her tongue inside, moving it all around Uiharu’s mouth. After tasting the inside of all of Uiharu’s mouth, she finally pulled away. “Sorry for making you wait so long, Uiharu. But you forgive me, right?” Saten put on her usual dorkish smile. Uiharu mumbled. “Idiot. You should have noticed my feelings sooner.” “Well don’t worry! I’ll make up for it” Saten squatted back down, pulling Uiharu’s wet panties down her legs as she moved. She then stood up and gently pushed Uiharu down on the bed. “Open up your legs, Uiharu.” “H-Huh?” Suddenly Uiharu’s face grew as red as can be. “T-T-THAT’S what you meant? You can’t! That place is dirty.” “It’s not dirty. Saten ran her index finger down the slit. It’s pretty and pink, and since it’s you I’m sure it’s clean. Well, think I’ll help myself.” She then leaned in and began licking. Her tongue glided up and down, slowly and sensually. Uiharu started to moan uncontrollably. It was all she knew how to do. Saten then moved her lips in to it, kissing and sucking on it. Uiharu gripped the bed sheets with all the strength her fragile hands could give. Saten thought a little to herself. Uiharu is so cute like this. She looks so adorable making that face and gripping the bed with her hands, and letting out those cute moans of hers. Yeah. There’s no denying it now. I’m in love with Uiharu, and she’s in love with me. As I’m here licking and sucking on her pussy, I’m trying to think of what’s next. Where do we go from here after this? Saten’s thoughts were interrupted when Uiharu expressed that she was reaching her limit. “Ahhh, Saten! C-Cumming! I’m…gonna cum!” It’s alright, Uiharu. Go ahead and cum thought Saten. “AAAAAAAHHHHHHHH!!” Uiharu let out a scream as she came. Saten slowly moved her face away, her tongue and face glistening from Uiharu’s naughty juices. Saten licked her lips, getting all the taste. “Wow, Uiharu. You must have liked it a lot. You came all over my face.” Uiharu was finally brought back to her senses. “Huh?” Her face grew bright red. “I-I-I’m sorry, Saten.” “It’s alright. You were so cute.” She smiled and stood back up. She led Uiharu back up as well so they were both standing again. They both leaned in and shared another deep, passionate kiss. “But…I was the only one feeling good. Don’t you want to feel good too?” Saten blushed at the thought of Uiharu doing the same kinds of dirty things to her. “Uh, well, the whole point was for me to make you feel better because you had a slight fever, right? So…” “You don’t think I can do it?” Uiharu made a sad puppy dog face. Gah! My weak spot! Saten sighed. “You could, I guess.” Saten perked up. “Here’s an idea. I know a way we can both feel good. “How’s that?” Uiharu asked while Saten began to strip her clothes off. Uiharu stared in awe for a second at Saten’s exposed body. She looks so pretty and her skin looks so smooth. Saten grabbed Uiharu’s hand and led them both to the bed where they both sat down. “Now just lay down.” Uiharu laid down on the bed. Saten turned around and laid on top of Uiharu so they were in a 69 position. “Now you lick my pussy, and I’ll lick yours! That way we can both feel good. Okay?” “W-W-Wait a second, Saten. Y-Y-You’re doing that again?” “Well, I’m digging in again!” Saten began licking Uiharu’s sensitive vaginal lips again. Uiharu began moaning and losing control. Saten stopped for a second. “C’mon, Uiharu. Didn’t you want to make me feel good too?” Uiharu gulped. “Well, I…..I’m digging in too, then.” Uiharu lifted her head a little to lick Saten’s lower lips. I wonder if I’m doing this right. Saten’s pussy is so pretty. I hope I can make it feel good. Saten began to moan and orgasm herself. “Yeah. Just like that.” Saten soon returned to licking. They both went back and forth licking each other and taking short breaks to let out a few gasps of pleasure. “This feels so good” Uiharu said on the brink of breaking. “But I can’t take it anymore, Saten! I’m at my limit. I’m….gonna cum again!” “Me too. I’m almost at my breaking point.” Both of them had thought the same word—together. Just then they both stopped licking to let out a cry in unison. The next day, all four girls—Misaka, Kuroko, Saten, and Uiharu were out walking casually in town… “So, are you feeling better now, Uiharu? Hoping resting at our dorm helped a little bit” said Kuroko. “Yeah, it did. I feel much better” exclaimed Uiharu. She turned to Misaka. “Sorry for using the room that pretty much half belongs to you.” “Hey, don’t worry about it, Uiharu” said Misaka. As long as you’re better, that’s all that matters, right? But I feel like I’m being left in the dark about something. In any case, let’s keep going.” Misaka walked on while the other three hang back for a second… “So, how did it go, you two? Did you do it?” Both of the girls blushed immensely. “Good job guys! I’m so proud!” She gave a thumbs up. Misaka turned around. “Hey, what are you guys standing around for?” She turned back around to keep walking, as if to remind them they were being left behind. Kuroko rushed back without another word to the two girls. “I’m on my way, Onee-sama! Please wait for me!” The two girls looked at each other for a second. “Yeah, let’s go, Saten” said Uiharu, reaching out her hand. She smiled. Saten smiled back. “Yeah.” She grabbed Uiharu’s hand, and the two continued to walk behind Kuroko and Misaka, with their hands linked. Chapter 5: Level 5: Misaka x Misaka 10032 Chapter Text Level 5: Misaka x Misaka 10032 It was Saturday afternoon. Misaka had woken up to find that Kuroko had gone out again for Judgment earlier. She decided to go out and treat herself to ice cream. She hadn’t been out in a while so she thought this was also a good time to explore the city a bit. While waiting in line at one of her favorites vendors she came across one of the Misaka sisters. It was Misaka 10032, who was petting a stray cat. The whole incident with Accelerator and the other sisters raced through her mind in a second as she looked at the sister from the line… “Ma’am? Ma’am? Here’s your order.” “Oh, yes. Thanks.” Misaka took the ice cream. “Actually, can I get another one?” “For the level 5, Misaka Mikoto? Sure. And this one’s on the house!” Misaka had taken the two ice cream cones and approached the Misaka sister. She paused for a moment as she watched this sister pet a stray cat near one of the alleys nearby. She had wondered why a sister would take interest in such a thing. Just then, a woman appeared with a worried look on her face asking people if they had seen her cat. The Misaka sister had picked up the cat. The woman had noticed that that was her cat and she ran toward the sister, who gently returned the cat to the owner, who was now in tears of joy. The Misaka sister turned around and finally noticed Misaka who was standing behind her. “Here.” She said. Would you like one?” “Why yes.” The sister replied. “I would like to get a taste of this treat that people enjoy.” “Hey. You’re not doing that thing you do when you speak!” Exclaimed Misaka. “What thing?” “You don’t know.” Misaka had a face that encompassed both confusion, and disappointment. “You know. You say how you said what you just said. “’I’m not sure what you mean, but while talking with some scientists-“ “Let’s take this to a table.” Misaka interrupted. … While both of them were sitting down at a table outside near the vendor, they started to continue where they left off. “You were saying you recently had a conversation with scientists lately?” Misaka asked. “Yes. They told me that I have matured since the incident with the other sisters and now I am behaving more like a normal human.” “Huh. That’s quite something. To think a clone would be able to pass for a normal human.” “And yet I do not understand everything about humans. They told me I should get to know more about the way humans act.” “Hey!” Exclaimed Misaka. She had thought of a good idea. “What if I teach you about how humans act?” 10032 still had that same stone face you’d see on a scientific copy, but she replied that she was indeed grateful for the offer. “Yes, that would be helpful.” She expressed. “How about we go back to my dorm room? Kuroko is gone for the time being so there would be no one to interrupt us.” “Yes. That sounds like a logical place.” At Misaka’s dorm room… “……and so you see. There are lots of things that make humans who they are.” Misaka had been explaining it with great detail for a while at this point. “Yes, but you missed something I read about a little while back.” “Oh? And what would that be?” Misaka pondered. “Sex.” Misaka 10032 has uttered with that same look on her face. Suddenly, Misaka had frozen. “Uh, well, I’m not sure I could do a good job teaching that sort of subject.” “Why not?” “Well, I…uh…don’t exactly have that much experience in that field myself.” Misaka 10032 had paused for a second before slowly walking up to Misaka and leaning in. She closed her eyes on kissed Misaka on the lips. Misaka’s eyes had widened. The clone slipped her tongue into Misaka’s mouth and began to move it around inside. W-What’s going on here? Why is my sister doing this? Oh, but…this feeling……isn’t too bad. 10032 slowly pulled away. Misaka was dazed and blushing for a second before coming to her senses. “W-What was that for?” She stammered. “I thought that since neither of us know much about it, we could try to learn together. I’ve heard there are several techniques that humans use to pleasure each other. But beyond that, I do not know. Did you not enjoy the kiss?” Misaka placed two fingers on her lips and thought to herself. Did I? Now that I think about it, I didn’t try to shove her away. Her lips felt warm and soft. Her moist tongue seemed to caress mine. I’m still in shock from it. “I…..I did…..” Misaka muttered. A red color covered her face. “Then…” 10032 Reached out, grabbed Misaka by the cheeks, puller her face in, and kissed her again. The clone took a break to glide her tongue across Misaka’s lips. Misaka took the chance to gasp for air. “…let’s continue to learn more.” The sister removed her goggles and set them on the desk. She then turned back to Misaka, who was now in a daze and blushing, and kissed her again. This time Misaka was completely submissive. She accepted it, embraced it. She was entranced by the clone’s surprisingly aggressive sexual advances. The sister moved her hand down Misaka’s waist down to her skirt and slid it inside. Misaka could be heard moaning from the sensation of her sister moving her fingers inside her skirt and shorts. Her legs began to quiver. 10032 removed her hand and stopped kissing Misaka. Misaka was panting due to the intensity of the experience. The sister softly pinned a consenting Misaka down on her bed and began to move her tongue up and down her neck. She savored the taste of Misaka’s sweat on her warm skin. Misaka began to whimper. Mmmm…Her tongue feels so comforting. It feels like I’m melting away in this warmth. Misaka closed her eyes and allowed the sister to take her. The sister then led Misaka back up and removed her vest, unbuttoning her shirt. She lightly pinned her down again, now caressing her with her tongue. Misaka couldn’t hold it in much longer. She started to let out her pent up noises. Her breathing grew heavy and she began to sweat even more. Ahh. My body’s….getting hot. Her tongue is so soft and warm for an artificial creation. The clone undid Misaka’s bra, who then sat up, slipped out of it and her unbuttoned shirt, leaving her top half exposed. She quickly covered her breasts with her arms in embarrassment. But the clone lightly moved them away, and pinned her down again. She licked and sucked on Misaka’s nipples continuously for what seemed like forever. Misaka’s legs began to squirm as her upper body was licked and caressed by her sister’s tongue. The sister let go once again and moved her hands down to Misaka’s skirt and pulled it off. By the time Misaka realized what was going on, the clone was already undoing her shorts that she usually wears underneath. Misaka suddenly came out of her daze. “Wh-What are you doing?” She nearly shouted in embarrassment. “I am merely removing the rest of your clothes as there are still things to learn.” She removed Misaka’s shorts and panties. “I have heard about other things that feel even better than kisses. I want to know how they make you feel.” Misaka suddenly sat up on the bed. “Wh-Where exactly did you get this information about ‘techniques’?” A strong sense of necessary curiosity accompanied her embarrassment. “I was in the library using a computer researching more on how humans act and the subject of sex came up, with lots of different techniques. But I didn’t see anything on how humans react to these techniques.” Misaka let out an uneasy laugh. “Ahh ha….ha. I see.” “So I was hoping I could see how you react to my various advances.” “But that’s….” Before she could finish, the sister got down on her knees on to the floor, lightly spread open Misak’s legs, leaned in, and started licking her most sensitive area. Misaka leaned back as the intense pleasure consumed her. Ahh. What is this feeling? I’ve never felt like this before. She’s……She’s licking down there. That place is dirty….but…..She gripped the bed sheets with all her might. It feels…..good. I can’t believe this is making me feel this way. “Mmpf. Ahh!~” I’m letting out lewd noises… To think my own sister would be licking me down there. The sister inserted her index and middle finger inside while she continued to lick slowly but feverously at Misaka’s lower lips. This sent her over the edge. She began clawing at the bed sheets she had been grasping so firmly. The sister pumped them in and out over and over as Misaka continued to orgasm.”Ahh, something’s coming. It’s….Ahhh.” She began to lose strength. She collapsed back onto her back on the bed. “I’m going to…..I’m going to…..” Misaka gripped the sheets with the last of her will. “Ahhhhhhhhhhhnnnn~~!!!!” The sister pulled her fingers out and leaned back. She licked her fingers to clean them from the juices that Misaka had released. She stood up. “I wonder what that was.” She looked at the clock. “Oh. It’s starting to get late. It’s time for me to get going. I will do more research on this subject. There is still much I want to know about human reactions, especially to sexual encounters.” She cleaned Misaka, who had passed out and was now asleep, with a warm cloth to dry her of her sweat and tucked her into her bed, and left. Later at night… “Ahh!!” Kuroko stammered as she burst in through the door. “I can’t believe I had to be gone all day! Stupid Judgement.” She looked and saw Misaka sleeping in her bed. “And my dear Onee-sama has already gone to sleep. I cannot talk to her before I get to bed now!” She sighed. “Oh, well. I guess there’s tomorrow. Heh heh heh heh.” A sinister smile crossed her face as she began to drool from her lewd fantasies. After a second she looked on the desk and saw a pair of goggles that the clone had left. “I wonder how these got here…Probably nothing I need to be concerned about.” And she headed off to sleep as well. Chapter 6: Level 6: Kuroko x Uiharu Chapter Text Level 6: Kuroko x Uiharu It was just another day at Judgment HQ. Uiharu and Kuroko were the only ones in the room while investigating a case while the others were out doing other business. Uiharu was typing something on the computer. It was pretty slow so Kuroko, who was wandering aimlessly and aggravated starting to get bored. “Ahhhhh! Why do I even have to be here today? There’s nothing to do! I should be with my beloved Onee-sama!” Kuroko yelled in a fit. “Please calm down, Shirai. Work at Judgment is very important. Please be patient” Said Uiharu “Oh. I just a message from Konori.” “We captured the criminal already. So you can go home now since there are no more cases to take care of.” -Konori Uiharu stretched. “Guess we can go now, Shirai.” “FINALLY.” Kuroko stammered. “Let’s go…..AW DAMMIT! I forgot Onee-sama is busy today talking to some scientists about some experiment.” “Well, as long as we don’t have a repeat of the sister incident then that’s good, right?” Asked Uiharu. “Yeah, yeah. Anyway, since I’m suddenly free, do you wanna do something, Uiharu?” “Saten’s at the library studying so I don’t want to distract her. So sure.” Let’s hope she’s actually studying. It’s not really her style… “Wanna go back to my and Onee-sama’s place and just laze around?” Asked Kuroko. “Sure.” Uiharu’s stomach grumbled. “But how about some lunch first? There’s something I want to talk about, actually.” “Yeah, sure.” A little later… Kuroko and Uiharu were eating lunch outside at a table. It was a little early in the day for lunch so they were the only ones outside eating. Kuroko was slurping up the last of her drink. “So, what did you want to talk about?” She asked. “Well…um….” Uiharu mumbled. Her face suddenly lit up red as she tried to find the right words. “You see…” She took a deep breath. “Saten and I had sex but I have absolutely no idea what to make of it. So are we lovers now? I don’t know.” Kuroko spit out the last of the drink she had in her mouth at incredible speed and force. “You did had WHAT?” She turned away hiding an embarrassed look. Well, I guess I can’t be too critical. Me and Onee-sama have had sex twice now… and there was that time with Konori… She turned her head back again, facing Uiharu. “Anyway, go on.” “So, we had sex, but is that enough to consider us a c-couple?” Uiharu suddenly got embarrassed saying the word ‘couple.’ …..”I’m not sure. I’m pretty sure what I did wasn’t enough to pleasure her enough.” Kuroko suddenly smirked. “Oh? So that’s what this is about.” Uiharu looked down in embarrassment. “You want a better grasp on how to give Saten what she wants.” “Y-You don’t have to put it so bluntly.” She stammered. Kuroko suggestively got close to Uiharu, who was noticeably flustered. “I could teach you how.” Kuroko whispered. “W-W-W-WHAT?” Uiharu’s face turned completely red. “Shh! Keep your voice down.” Kuroko whispered again. Uiharu suddenly covered her mouth in embarrassment. “And how exactly do you know how?” She whispered. “I just do.” Kuroko whispered back. “Come on. Let’s go back to my and Onee-sama’s room. It’s okay since she’s out today with some scientists, remember? And you and Saten aren’t a couple yet so if we do it, it’s okay” Uiharu wanted to refuse. It was such flimsy and perverted logic. But she couldn’t. She only sat there blushing for a while. She loved Saten, and if this meant she could learn how to better pleasure her, she was willing to do it. She breathed in. “Okay.” She whispered. “Let’s go.” A large grin graced Kuroko’s face. “Alright, then!” She exclaimed. She grabbed Uiharu’s hand and off they went. At the dorm… “Alright! Let’s get started!” Shouted an eager Kuroko. I’m gonna show you how it’s done and then you join in with me. Just pretend I’m Saten.” “H-Huh? B-B-But this is so sudden and-“ The aggressive girl’s lips had collided with the innocent girl’s. Kuroko’s tongue invaded Uiharu’s mouth, placing her hands on the black haired girl’s cheeks as her tongue swirled and attacked Uiharu’s from every direction. Kuroko put her knee in between Uiharu’s legs and began to rub it underneath her skirt up and down her panties. She could feel Uiharu start to shiver at the sensation. Why is my heart beating so fast? Ahh…My body….is getting really hot. Shirai’s tongue is so soft and warm. I…..want to give Saten this same kind of feeling…They had both closed their eyes in passion now. The innocent girl began to fight back against her aggressor, pushing forward into the redhead’s mouth and grabbing her shoulders. Both of them started to moan as their tongues rolled around each other’s. Kuroko could feel the juices leaking from Uiharu’s panties with her knee. Ahh…I’m getting wet, just from this intense kissing. The two’s legs began moving more and more before they tripped over onto Kuroko’s bed, their lips still locked. Kuroko laid on top, and Uiharu underneath. While their moans grew louder, Kuroko slid her hand up Uiharu’s waist to her chest and pulled her school neckerchief untied and tossed it aside. Finally, their lips parted and both of them took deep breaths and began to pant. They stared into each other’s eyes for a second. “Sh-Shirai….I….” Uiharu said in a weak voice. Kuroko placed a finger on Uiharu’s lips to quiet her. “Shh.” She brought herself and the black haired girl up to their knees on the bed. “We’re only just beginning.” She removed Uiharu’s top and bra and tossed them onto the floor. She began to lick her neck and her chest, slowly and warmly caressing her body with her tongue. The innocent girl’s trembling body was so fragile and like silk. Uiharu is actually pretty cute. Her waist is so thin and her body is so delicate. The level 1 held her hand over her mouth and her eyes closed as if trying so hard to keep her moans of pleasure from escaping her lips. Kuroko moved to Uiharu’s chest, licking around and sucking her nipples. “Wow, Uiharu. You must really like this. They’re hardening.” The innocent girl covered her face in embarrassment. “Okay. Now you do the same to me.” Kuroko removed her vest, unbuttoned her shirt, removed her bra and tossed them aside. “O-Okay.” She muttered. They revered their positions so now the innocent girl was on top. She leaned in closer, sticking out her tongue. Her heart was beating faster and faster. I can’t believe I’m about to l-lick Shirai. But if it will help me with Saten, I’ll do it. Uiharu began sliding her tongue across the redhead’s body. The aggressive girl had suddenly seemed shy and reserved. She began trembling. Uiharu moved to Kuroko’s breasts and began sucking them, swirling her tongue around her nipples, in a way similar to how Kuroko did it. The aggressive girl let out a squeal. Shirai’s nipples are getting hard just like mine did. I wonder if she likes this? Maybe I can make her feel better if I use my hand. Uiharu took her hand and slid it down Kuroko’s body to her skirt and slipped it inside her panties. Her fingers found themselves rubbing and brushing up against her most sensitive area. Uiharu moved her fingers up and down, while she continued licking all over Kuroko’s body. She let out some soft moans. “Ahh. W-Wait. Uiharu, if you do that I’ll-“ But Uiharu couldn’t hear her. She was too focused on pleasuring Kuroko, so she could know what to do to Saten. Ahh. It’s coming, just from this. Uiharu is too good. Kuroko began to pant. “Uiharu…If you…ahhh…keep doing that, I’ll….I’ll...AAAHHHHHHNN!~” Uiharu suddenly came to her senses. She could feel Kuroko’s juices on her fingers. Her face suddenly lit up red and her eyes widened. “O-Oh my gosh. I-I’m sorry!” She quickly remover her hand from the twin tail’s panties from within her skirt. They both sat up. “No, it’s okay. I’m just a little surprised that you’d be the one to make me cum first.” She grinned. “You’re a lot more forward than I thought.” Uiharu just looked down in embarrassed silence. “Well, now that we’re done with that, let’s get to the last thing. Let me just get out of my dirty clothes first.” Kuroko got off the bed and pulled down her skirt and then her underwear. “Lay down on the side of the bed.” Uiharu laid down on the bed. Kuroko got on her knees on the floor and pulled off the level 1’s skirt and panties from her legs. “W-Wait. Are you going to….l-lick THAT place?” “Well, of course. If I need to teach you how to pleasure Saten’s body I need to demonstrate on the most important place, don’t I?” “B-B-But-“ “Just lay down and keep in mind how I do this.” Kuroko started kissing Uiharu’s ankles, slowly moving up to her thighs. She reached her hands in and gently spread the innocent girl’s legs apart. She leaned in closer kissing and licking the inside of her thighs. A tingling sensation ran through the innocent girl’s body before she felt a sudden charge. The aggressive girl had started licking the most sensitive part of her body. Uiharu gripped the sheets with all the force her delicate hands could use. She started moaning uncontrollably, letting out gasps of pleasure. Her body started to sweat. Shirai’s tongue is gliding over my pussy. Ahh, I feel really weird, but…it feels good. Shirai’s tongue is so soft and warm. This almost feels as good as when Saten did this to me. My mind is going blank. I’m losing myself. Uiharu started to relax. She loosened her grip on the sheets. She relented and let herself become lost in the pleasure as she orgasmed earnestly. She moved her hands to Kuroko’s hair and untied the ribbons in her hair so it flowed freely. Uiharu weaved her fingers through. I’m at my limit. Something’s coming. I can’t hold back much longer. Kuroko stopped licking for the moment. “Then you need to use your fingers. Pay attention to how I do this.” The level 4 slowly inserted her middle finger inside, and then her index finger. Uiharu looked like she was about to break. Kuroko clawed and scratched at the inner walls. Uiharu couldn’t take it anymore. “Shirai! I can’t hold back anymore. I’m going to cum!” “Don’t hold back. Just let it all out.” Uiharu let out a scream of pleasure. “AAAAAAAAHHHHHNNN!~” Juices sprayed all over Kuroko’s face. The redhead sucked her fingers and licked her lips in delight before wiping the rest off. Uiharu began to pant. “Did you get all that? Great, now do the same to me.” “W-What? B-But I-“ She was still flinching and letting out hiccups from the climax she just experienced. “Hurry up already!” She stood up and grabbed Uiharu’s hand and pulled her up off the bed. Uiharu gulped. “Okay.” She muttered. She crouched down in between Kuroko’s legs. Her mind was blank. Unsure of what to do, she closed her eyes and plunged her index and middle fingers inside and began pumping them. “Ahhn!” A shock went up Kuroko’s spine. “My, you’re certainly the pugnacious one, aren’t you?” The wreath wearing girl blushed in embarrassment. Uiharu’s fingers feel so good. They’re long and slender pumping in and out of me at amazing speed. If this keeps up, it won’t be much longer before I cum again. And then, the innocent girl touched her tongue to the redhead’s vaginal lips. Ahh! I’m at my limit. She’s too good! “Uiharu…I…AAAAAAAAHHHHHHHNNN!~” All of Kuroko’s naughty juices had covered a dumbfounded Uiharu, almost as if she was unsure what was now covering her face and fingers. Kuroko trembled as she fell to the floor on her knees with Uiharu. “Heh. Wow, Uiharu. You really know how to pleasure a girl. Saten is sure to feel good if you did to her what you did to me.” “You really think so?” Uiharu brightened up. “Of course.” Kuroko got up and got a cloth from the bathroom, and handed it to Uiharu. “Now clean yourself up. It’s starting to get late.” Uiharu noticed the time. “Ahh, you’re right! I’ll see you later, Shirai!” She hurriedly changed back into her clothes after cleaning up with the cloth and charged out of the room. Shortly after, Misaka entered… “Hey, Kuroko. Sorry I took so long getting back. After talking with the researchers I ran into Saten and-“ She noticed her roommate had no clothes on. “Onee-sama! You’re back!” She lunged into the air in her usual attempt to pounce on Misaka.” But her attempt was thwarted by a strong roundhouse kick, which sent her back to the floor. “Why the hell are you naked?!” Her face turned red. “But Onee-sama. This way you can truly embrace me as a woman!” She had a noticeable red mark on her face from the kick. “I don’t need that right now!” She stammered. She sighed. “It’s been a long day. I’m gonna rest in bed.” “Can I sleep with you?!” “*Sigh* Alright. But put something on.” “Okay!” They both got in Misaka’s bed after Kuroko put some casual clothes on. Stupid Kuroko. She smiled as they fell asleep. Meanwhile… “Oh, Saten! Hey, Saten!” Uiharu was nearly shouting as she was running down the street. She finally caught up. “Oh, hey, Uiharu. Where have you been?” “Oh, just hanging out with Kuroko. What about you?” “I was just, uh, hanging out with Misaka. Yeah. Just hanging out, haha.” Uiharu looked puzzled. “Let’s get going.” Uiharu smiled. “Yeah. I learned a lot of interesting things I want to show you.”
