For the Mistress
Tags: Yuri, filming, incest
Liz yawned as she headed to the kitchen for a quick snack before bed, pausing when she noticed a light on in the living room. It wasn't very late, but she hadn't thought anyone else was still up. She poked her head into the room to see her sister, Sella, sitting in front of the coffee table, her back to the doorway.
Liz tilted her head as she noticed that Sella's attention was on the laptop in front of her. She was pretty sure that was Illya's laptop. What was Sella doing with it? Curious, she quietly crept into the room with a practice born of years of avoiding being noticed by Sella so she wouldn't be pestered into doing chores. As she got close, Liz crouched behind her and looked over her sister's shoulder to see what she was doing.
"Ecchi," Liz said immediately, her tone flat as usual. Sella jumped in fright, hand clamping over her mouth. She whirled to face Liz, panic clear on her face. Liz just looked at her flatly, and then looked back on the screen.
There was a video playing featuring two women with blonde hair, completely naked and obviously having sex. Liz recognized the website as a popular porn site and could clearly read the title of the video, "Busty Blonde Twins Gone Wild."
"N-no!" Sella half-yelled half-whispered. "No, it's not what it looks like! I saw Illya's laptop on the table, and I decided to take a look at it. I mean, you know how weird she's been acting lately, and I thought that maybe I could find out why if I took a look, maybe a message or a website she's been visiting a lot that would explain it."
"Snooping," Liz chided her.
Sella blushed. "Yes, but only because I'm worried about her! It's our duty to look after Illya and make sure she's okay. So I looked in her browsing history and found…this." Sella turned back to the laptop. "A lot of this, actually. It wasn't just this one video."
Liz shrugged. "All like this? Girls?"
Sella nodded. "It's not just that it's only women," she said, a bit of discomfort in her voice. "It's mostly…incest. Usually twins."
"Kinky."
"Liz!" Sella snapped. "This is serious! Illya is watching these kinds of videos online!"
Liz shrugged. "Normal when going through puberty. Exploring."
Sella bit her lip and looked away. "Maybe. No, you're right. It's surprising, but I suppose it's better than her having a crush on Shirou." Liz didn't think it really made a difference either way, but she didn't voice her opinion. "A-and, well, if Illya prefers girls, then, of course, I'll support her." That was something Liz nodded in agreement with, though again, she didn't think it made a difference. They'd support Illya no matter what.
"But!" Sella said, suddenly more heated. "That doesn't make her watching these kinds of things okay! I was talking with Mrs. Imai from down the street and she said her son got horrible viruses on his computer that stole his credit card information because he was browsing sites like these. And she also said that the actresses are forced into it and are really mistreated. I can't abide by Illya taking part in something like that!"
Liz strongly suspected that Mrs. Imai didn't know the first thing about the porn industry and that her son, who she knew was a near-pathological liar, had probably spent money on something he shouldn't have and blamed it on a computer virus. But Liz didn't say any of that. She knew it would be fruitless to try to convince Sella otherwise.
"Can't stop her," Liz pointed out. "She'll just hide better."
Sella deflated a little. "I know," she said. When they took on their new roles as Illya's guardians they had both read a lot of material, provided by Irisviel, about child development and raising. "But we can't let her keep going on sites like this…it's dangerous."
Liz rolled her eyes. She knew porn sites were only dangerous if you were dumb enough to click on the ads, and that was assuming you weren't using an ad blocker in the first place. Unlike her uptight sister, Liz was a lot more comfortable with sex and had masturbated to porn on more than one occasion.
"We could make it for her," Liz joked, intending to poke fun at Sella for worrying about this so much.
As expected, Sella looked at her in shock. But to Liz's surprise, that shock slowly turned to thoughtfulness. "It would solve the problem of her going to dangerous websites. And we do match what she seems to prefer…"
Liz and Sella weren't twins, at least in terms of appearance. Though they did look unmistakably like sisters. Whether or not they were technically sisters was less clear, since both of them were homunculi created by the Einzberns. But, to Illya's knowledge, they were normal human sisters, and they considered each other sisters either way.
"Okay, let's go," Liz said, standing up. She had been joking, but Sella had either missed that or ignored it. Still, she wasn't opposed to the idea of having some harmless fun with her prude of a sister. And she got to tape it? She had to act quickly, before Sella came to her senses.
"R-right now?!" Sella exclaimed, suddenly nervous. "But I don't- we need to prepare, to get things-"
"I have everything," Liz told her. "In my bedroom. Camera, tripod, lights, toys."
"Why are you so prepared for this?" Sella asked in a panic. But she had stood up, and when Liz started heading to her bedroom, she followed.
Liz just grinned. "Reasons," she answered vaguely. "The sooner the better, right?"
"Well, I guess it would be better to take care of it early…" Sella agreed. "B-but I don't know if I'm emotionally prepared!"
"Shh, you'll wake others," Liz warned as they walked through the dark halls of the house and headed upstairs. Sella shut up at that and was quiet until the two of them arrived in Liz's bedroom.
Liz started digging in her closet, looking for her camera and tripod, and Sella stood there nervously. "I-I know I agreed to this, but now I'm starting to wonder if maybe this is a little ex-"
Liz whirled, camera in hand. "No, it's important," she insisted seriously. "For Illya's safety."
The two of them locked gazes for a moment before Sella nodded. "No, you're right. This is for Illya's sake. I'm just…nervous."
Liz internally sighed in relief. She had almost let Sella chicken out, and that would have been disappointing.
Neither of them spoke as Liz set up a camera on a tripod, getting a good angle of the bed. She also set up some lights and reflectors, knowing that without them it would be difficult to make them out in the video.
"...why are you so ready to do this?" Sella asked as she watched Liz's almost professional setup.
"Helped Iris film some stuff," Liz explained as she fiddled with the camera.
"Ah, right, her home video phase," Sella recalled. "I didn't realize you helped with that."
"She wanted to be in them," Liz said. "Needed someone else to film. I didn't mind. Was fun." She turned to face her sister and placed her hands on her hips. "Ready. Camera running. Sit on bed and strip."
"S-strip?" Sella asked, stuttering as it hit her what they were actually about to do. "I don't-" she started, but she was cut off as Liz started stripping her own clothes off. Sella froze as she watched her sister peel her clothes off.
Once upon a time, seeing Liz naked wouldn't have affected her at all. They were homunculi after all, and what did it matter if they had clothes on or not? But that had changed as the two of them lived like normal people. Irisviel had put a lot of effort into helping them grow into more than just automatons, and now there were days where Sella forgot they weren't normal humans.
But that came with a normal range of emotions, including embarrassment and nervousness as her sister's body was revealed to her. There was another emotion there too, hidden underneath the others, and she couldn't identify it.
Liz, now dressed only in her panties, turned to Sella and looked at her expectantly. But Sella didn't move, too nervous to proceed. Seeing this, Liz rolled her eyes and decided to do it herself. She approached the frozen woman and gently placed her hands on her shoulders. Sella allowed Liz to guide her to sit down on the bed, facing the camera.
Liz then climbed onto the bed herself, kneeling behind Sella. She smiled and winked at the camera before turning her attention to Sella. If Sella was going to make her do all the work, she was going to use the chance to make the video better.
With slow movements, so she didn't surprise Sella, Liz reached down and grabbed the hem of Sella's shirt and began to pull it upwards. At first, it didn't seem like Sella was going to cooperate, but after a moment of hesitation, she lifted her arms, allowing the garment to come off.
Sella's bra was a plain but cute light blue color. Liz was of the opinion that she could have gone without a bra and it wouldn't make a difference, but she kept those thoughts to herself. She enjoyed teasing her sister about her smaller chest, but it was never serious, and this wasn't the time for it.
Sella still seemed tense though. Liz had no problems with it herself, but she also understood that this was a lot for someone like Sella. Filming herself having sex with her sister to show to their pre-teen mistress? That's a big step up for someone who thought looking at porn was scandalous.
But Sella needed to enjoy it, or at least look like she was enjoying it, or the video wouldn't be sexy at all. Liz leaned down, putting her lips right next to Sella's ear. "Relax," she whispered, too quiet for the camera to pick up. "Remember. It's for Illya."
It took a moment, but Sella did relax a little at those words, and she nodded. Satisfied that she had done what she could, Liz turned back to the task of undressing her sister. The back clasp of her bra was quickly undone, allowing her to pull it off of her and throw it to the ground. Liz was pleased to see Sella frown at that. It meant she was more annoyed at Liz's casual treatment of her clothes than she was nervous about being topless in front of a camera.
Getting Sella's skirt off was a little more difficult, but Sella cooperated enough to make it happen. It was only then, with both of them wearing only their panties, that Liz decided it was time to make her first move.
Still sitting behind her, Liz reached up and cupped Sella's modest breasts in her hands. Sella flinched at first but forced herself to relax. She was suddenly much more aware of the camera pointed at her, with the dark lens and blinking red light. She blushed and averted her gaze from it as Liz continued to fondle her.
"S-shouldn't this be the other way around?" Sella asked in a quiet voice, not wanting the camera to pick it up. She was also trying really hard not to think about the strange sensations Liz was causing. "I'm…small," she admitted reluctantly. "Wouldn't it be…better to show off some bigger ones?"
"No," Liz denied flatly. "You're more expressive. And would be too hesitant if we switched." Liz followed her statement up by lightly running her fingers over Sella's hardened nipples.
Sella bit her lip as a thrill of pleasure shot through her, and she admitted that Liz was right. She wouldn't be able to do what Liz was doing to her now, too nervous and unsure.
Liz, on the other hand, was more interested in playing with her normally stuck-up sister. This was a rare opportunity, and there was no way she was going to give up the initiative. She shifted position slightly so she was pressing against Sella's back.
Sella was very aware of Liz's assets pressed against her back, the hardened nubs washing away any doubts about what she was feeling. Truth be told, it wasn't that unusual for her sister's boobs to press against her. They hugged, bumped into each other, or sparred. But, just like seeing her naked, the context changed things.
It didn't help that she could feel so much of Liz's bare skin pressed against her own. Not just her boobs, but her arms, her stomach, and even her legs as Liz held onto Sella between them.
And then she felt Liz's lips on the crook of her neck and she gasped, not able to hold it in. It was such a simple, innocent thing. A pair of lips against a relatively innocuous part of her body. But it burned, pleasantly so, to her senses.
Liz kissed her again, in a slightly different spot. And then again and again and again. Sella started breathing heavily, her heart beating like a war drum as Liz created a patch of burning skin on her shoulders and neck.
Sella had no experience with romance. She had never felt the desire to seek out a relationship, dedicated as she was to Irisviel and Illyasviel. And she was okay with that. But it left her in the dark and unsure when it came to physical intimacy. Was it supposed to feel like this? Was it normal for her body to be heating up so much her mind was going fuzzy, and for an itch to start slowly growing deep in her stomach? She wasn't sure, and that made her nervous, but it was offset by Liz's touch and reminding herself that this was for Illya's sake.
Liz was starting to grow excited as well. Like her sister, she had no practical experience with romance, but she had what she considered a healthy interest in it. She wasn't lost, but it was the first time she had experienced what it was to bring another person sexual pleasure. And she was getting very into it. Enough so that she was ready, and even eager, to move to the next step.
She pulled away from Sella, who looked at her questioningly. Disappointment that she had stopped flashed on Sella's face, though Liz wasn't sure if Sella even realized it. Liz smiled at her to reassure her before pulling her backward.
Sella allowed herself to be guided into laying down on the bed, perpendicular to the camera so it could see all of her. Liz climbed on top of her, and Sella reflexively covered her chest with her arms.
Liz gently grabbed Sella's wrists and moved her arms out of the way, pinning them to the bed on either side of her head. Sella blushed a deep red and averted her eyes from Liz's gentle stare as Liz pressed her body against Sella's. A jolt of pleasure shot through both of them as their nipples brushed against each other.
"Now we start for real," Liz said before lowering her face towards Sella's. It wasn't until Liz's face was just an inch away that Sella realized what was about to happen, and her eyes widened.
And then all thoughts left her head as Liz's lips met her own, pushed out by the wave of something that flowed through her. She lacked the ability to describe the feeling, only that it was warm and good and thinking was impossible.
That warmth turned scalding as Liz's mouth opened, and her tongue pressed against Sella's lips. Sella opened her mouth on instinct, and her mind went white with pleasure at the taste and sensation of Liz's tongue on her own.
Time had stopped meaning anything as both of them lost themselves in the kiss. Liz's hands slide up Sella's forearms, no longer pinning her but instead intertwining her fingers with her sisters, holding hands as they made out.
Liz was a little more cognizant than Sella, and she was surprised at how much she was enjoying this. She'd never felt particularly attracted to women, or her sister for that matter, but now that they had started, her heart was beating just as fast as Sella's, and there was a hunger in her gut that called for more.
A hunger that sharpened when Liz shifted her position, accidentally, or perhaps subconsciously, pressing her leg between Sella's, putting pressure on her crotch, causing Sella to let out a shocked noise of pleasure.
They both paused when that happened, their lips separating from each other as they looked at one another, chests heaving as they tried to catch their breath. Each inhale caused their breasts to press against each other more, and they could feel each other's heartbeat through that connection.
Liz shifted her leg, rubbing Sella's crotch, and Sella's face twisted in pleasure as a small moan escaped her lips. Liz grinned, expressing more than Sella had ever seen her do before, and equal amounts of dread and excitement washed over Sella.
Liz let go of Sella's hands and repositioned herself. Sella watched her with bated breath, wondering what her sister was going to do next. Liz's hand moved downwards, fingers lightly trailing down her body as she went, and Sella shivered at her touch.
Liz's fingers traveled down her arm, across her collarbone, and down between her breasts. There, she waved her hand back and forth, caressing Sella's stomach, almost tickling her, but it was far more sensual than just tickling.
Liz's hand got lower and lower until it was just above the waistband of her panties, where she stopped. Once again, the two sisters locked eyes, wordlessly communicating with each other. Liz was hungry and excited. Sella was nervous but anticipatory. And so Liz slid her hand further down, under Sella's panties, and ran her finger along her sister's dripping wet slit.
Sella let out a breathy noise halfway between a moan and a gasp as Liz touched her most sensitive spot. It was only then that she realized how wet she had gotten down there, a first for the normally prudish homunculus. Those thoughts were quickly washed away by the lightning that shot through her at every touch.
Liz was also lost in the feeling, marveling at how it felt to do this to someone that wasn't herself, and watching Sella's face twist and hearing her noises of enjoyment was fascinating and arousing. Liz started going through all the different ways she had learned to touch herself when masturbating, but doing them to Sella, observing her reactions to each one.
Sella squirmed and moaned under Liz's touch. She had long forgotten about the camera watching them, or why they were doing this. All she cared about was the ecstasy that was flowing through her like electricity, lighting up her nerves. A small part of her mind cursed her past self for not indulging in this kind of activity sooner.
That was when Liz ran out of ways to stimulate Sella's outer lips and clit, and decided to go further by pushing a finger inside of her sister.
Sella inhaled sharply as Liz's fingers penetrated her deep insides. It was the first time anything had gone in there. In truth, it was only her knowledge that her body was the same as a normal human's, at least in terms of form, that made her think she even had a vagina. And now it was finally being used.
Liz grunted slightly, having expected the resistance. After all, her first time masturbating had been like that too, a byproduct of being a homunculus. She used that experience to the fullest to make sure Sella's first penetration was a pleasant one. Her's hadn't been, because she had rushed. So she took her time here, watching Sella's face twist and contort in pleasure, her eyes screwed shut.
It took some minutes, but Liz eventually got Sella to the point where she could move her finger freely without causing Sella pain. Which meant she could start on the fun stuff. She rotated her hand slightly so her palm faced upwards and then slowly bent her finger inwards, searching along the top wall of Sella's passage.
It didn't take her long to find the spot she was looking for, the same one she had discovered on her own. When she pressed against it, Sella's back arched and she inhaled sharply. Liz grinned again, delighted by the reactions she was getting out of her sister, before pressing up harder against that spot, repeatedly pressing against it.
If Liz's earlier touches had sent tingles and shocks through her, then what she was doing now was a veritable storm. Thunder and lightning coursed through her body as Liz hammered away at the spot inside her that felt like a bundle of pure pleasure. This was sex? Sex felt this good? She couldn't bear it, couldn't withstand the pressure inside of her begging for release.
And then it burst free, and Sella's mind went blank as she experienced her first-ever orgasm. She put her fist in front of her mouth to try to muffle her high-pitched moan. The pleasure overwhelmed her thought, and it was all she could do to not thrash about.
Liz watched, finger still trapped in Sella, her other hand between her legs as she touched herself. Like her sister, Liz was regretting never branching out before. Making someone else feel like this was just as good as masturbating, albeit in a slightly different way.
Sella's orgasm eventually petered out, and she lay there in a daze, chest heaving as she recovered her breath. She knew enough to know what an orgasm was, she was inexperienced, not ignorant. She knew it was meant to feel good. But knowing and experiencing were apparently two very different things. If orgasms were like this…then maybe she needed to reevaluate some things.
Sella flinched, suddenly feeling something pressing against her groin, and looked down. Her eyes widened at what she saw. Somehow, without her realizing it, Liz had removed both of their panties and positioned herself between Sella's legs. One of Liz's legs arched over one of hers, and the other was under Sella's other leg. Liz had her hands wrapped around Sella's thigh and had brought her crotch to her own.
"What…what is this?" Sella asked, still a little out of breath.
"Scissoring," Liz replied. Sella could see immediately why it was called that, considering the position of their legs. "Should feel good. It's also fun to watch."
Sella blushed and looked at the camera. She had gotten so caught up in the sensations that she had forgotten about it. Liz, seeing her sister acknowledge the camera, started moving, seeking to distract her.
It worked, and Sella let out a small noise of surprise as Liz pressed her lower lips against Sella's. Liz blinked as well, surprised at how good it felt. She'd seen this position in porn at times but had never expected much from it, thinking it was one of those positions that looked sexy but, in reality, wasn't very good. Porn was filled with falsehoods like that.
But as she shifted her hips slightly, she felt her clit scrape over Sella and could feel the telltale bump of Sella's clit. She shifted again and bit her lip at the sensation. Sella gasped, still sensitive from her recent orgasm.
Liz went back to watching Sella's face as she continued to shift her hips, slowly learning the best way to move to maximize Sella's pleasure, using Sella's expression and her quiet moans to measure it. She also tried to make herself feel good, but she found more enjoyment in getting reactions out of Sella.
Still, before long, Liz found a good rhythm that felt good for both of them, and she was surprised when her own quiet voice joined Sella's. She'd never made any noise when masturbating alone, but this was so much more intense than that, and she couldn't hold back her voice.
Sella was looking back at her now, as fascinated with this new side of her sister as Liz was with her. As one, they reached out the other with a hand and interlocked their fingers once more. They stared into each other's eyes as they moved their hips in tandem. Countless information passed between them, and they felt more connected than they ever had before.
As they both approached orgasm, they could feel that the other one was as well. Their rhythm shifted as they sped up, building up towards that climax. Their breathing grew heavier, their chests heaving, as their movements became more frantic.
They came at the same time, their grip on each other's hand tightening as they cried out. They shuddered with pleasure as their orgasms wracked their body, and the shuddering only stimulated them further. The small part of Sella's mind capable of thought noted that this orgasm felt a little different from her other one, where Liz was experiencing the strongest orgasm she'd ever had. Her masturbation couldn't compare.
Both sisters let themselves fall backward, their hands letting each other go as they splayed out. For a moment, the only sound in the room was their labored breathing.
"Do- do you think we made a good video for Illya?" Sella asked after a moment.
"We're not done yet," Liz said after a moment, sitting up.
"What?" Sella asked, confused. She still had the stamina to keep going?
"Still lots of things to try," Liz said as she repositioned herself, moving her head to between Sella's legs.
Sella's eyes widened, but before she could say anything, Liz's tongue was lapping at her still sensitive sex. Any protest Sella might have had faded away, and she let herself be carried away by the wave of pleasure.
"I'd like to start by saying that, no matter what, we care for you and will be here to support you," Sella said in an affectionate tone.
"O-okay," Illya replied, suddenly far more nervous than she was before. Sella and Liz had both approached her and asked to speak with her in private. Now the three of them were in her room, and for some reason, they had brought her laptop?
Illya looked at the two of them. Sella seemed…embarrassed? But very serious. Liz was harder to read, but Illya had lived with her long enough to see the small smile in her eyes. She was amused by something. They also both looked tired, with slight bags under their eyes.
Illya was afraid that maybe they had noticed something about her magical girl activities, but their expressions made her doubt that. But if it wasn't that, she had no idea what they could possibly want to talk to her about.
"Last night I found something on your computer," Sella said gently. "I found the videos you've been watching." Sella paused and looked at her expectantly, but Illya just furrowed her brow. "The more…adult ones?" Sella clarified, seeing her confusion. Illya shook her head, nothing coming to mind.
"The porn," Liz said, discarding any tact.
"W-what?!" Illya exclaimed, eyes widening. "But- I didn't- you-"
"Now now," Sella cut the young girl off. "You're not in trouble. I think it's a little early for you to be looking at that kind of thing, but an interest in that sort of thing is perfectly normal in a developing young woman such as yourself."
"Sella I-" Illya tried to interrupt.
But Sella kept going, rolling over Illya's protest. "But what's not acceptable is you visiting those kinds of sites. Web sites like that are shady and dangerous, and many of them are downright morally degrading to women."
"Wha-"
"But rather than ban you from watching this kind of thing altogether, we've come up with an alternative and safe method." Illya noticed at this point that Sella was blushing. Why was she blushing? "What I'm saying is…Liz and I…created some for you. So you no longer need to visit those sites."
Illya's brow furrowed in confusion for a moment, still trying to catch up with what was even happening. But the moment it clicked into place she froze, something snapping in her mind.
Illya's panic rose as Sella turned to the laptop and pulled up a video player. Her eyes widened and her heart started beating faster, but no matter how much she dreaded what was about to happen, she couldn't move her body, not even to look away.
And then the video started playing.
Illya wasn't sure how long it was. Time no longer felt like a real thing, like something that could be measured. But she watched it. From start to finish, she watched her two aunts, one whom she viewed as a second mother and the other who she saw as a big sister, make love to each other.
Each time she thought that it was over they'd just keep going. And the sound, oh god, the sound. It echoed through the otherwise silent room, playing from the tinny speakers of her laptop. She was sure she'd hear those sounds in her dreams.
By the end of it, Illya's mind was numb, and she couldn't comprehend the full scope of what just happened.
"I-Illya?" Sella asked, wringing her hands.
Illya looked at Sella with dead eyes. "I- I didn't look up those videos," Illya finally said. "Onii-chan's laptop is at the repair shop, so I let him borrow mine." Normally she wouldn't rat out Shirou like that, but she was beyond the point of being able to think through the implication of her words.
Sella was the one to freeze this time as understanding dawned on her. Her face quickly grew scarlet and she started to shake.
"SHIROOOOOOOOOOUUUUUUU!" she yelled, loud enough to be heard by the neighbors. She rushed for the door leading from her bedroom. "WHAT THE HELL DID YOU THINK YOU WERE DOING ON YOUR SISTER'S LAPTOP?!"
As Sella left the room, Illya's eyes shifted to Liz. Contrasted against her sister, Liz seemed unaffected by the news. She met Illya's gaze and shrugged. "Sorry," she said. Liz then also strode for the door. "I'll make sure she doesn't kill him."
And just like that, Illya was left alone in her room, the sounds of Sella yelling at Shirou in the background. Well, not completely alone. As Illya sat there, unmoving, Ruby slipped out from her hiding spot and approached the laptop.
"Oh-ho, that was quite the surprise," Ruby said cheerfully. She transformed slightly, a USB appearing at the bottom of her handle, before plugging herself into the laptop. "I'm definitely saving that to show to Sapphire-chan."
Normally Illya would stop Ruby from doing something like that, or would try to at least, but she just didn't have it in her right now. Instead, she slumped forward, burying her face in her hands. Flashes of the video kept playing in her mind.
"Ruby, can you just erase those memories from my mind?" Illya asked, despair in her voice.
"Download complete!" Ruby announced before unplugging from the laptop and turning to Illya. "And can do! Though I might get a few more than that as well!" With those words, Ruby turned into a comically large wooden mallet and brandished it threateningly.
But Illya just looked up and nodded before offering the top of her head. "I'm willing to take that risk," she responded seriously.
"Eh?!" Ruby replied, confused. The sentient magical wand had mostly been joking in her normal way, fully expecting Illya to take back her request in an amusing panic. But apparently, she had underestimated how much Illya had been affected. She quickly turned back to her default form and floated closer to Illya.
"Hey, cheer up," she encouraged Illya. "Look on the bright side!"
"What bright side?" Illya asked dully, looking at Ruby.
"Now we know what your Onii-chan is into," Ruby whispered mischievously. "Perhaps you can use that to catch his eye?"
Illya started at Ruby for a moment before her face grew red. "R-ruby!" Illya protested. "You can't just- how would I even- I mean with who- no!"
"But you'd be ignoring the best chance you have!" Ruby protested. "I can just whip up a clone of you real quick and the two of you can-" Ruby's plan is cut off as a pillow slams into her, knocking her into the ground and muffling her voice.
Illya stood there, red-faced, eyes unfocused, and panting. "T-that's enough! No more lewd things! I can't take anymore today! I'm going to bed!"
Ruby slipped out from under the pillow. "But you just woke up!"
"I don't care!" Illya snapped back as she climbed back into her bed and put a pillow over her head. Ruby could tell that there was no way she was going to be able to fall asleep. Not when she was that worked up and the sound of Sella's yelling was still clearly ringing through the walls. But Ruby sighed and let the girl be.
She floated out the window and decided to go visit her sister, Sapphire. She just had to share what had happened.

AN: This was inspired by a lovely image I stumbled on featuring these two homunculus siblings having some fun together. So I decided to make it happen. I've never written smut that was purely girl-on-girl before. It was fun. And a little difficult. Though, more than the yuri aspect of it, describing things from both perspectives, swapping between them, while using the 3rd person was perhaps stranger.
Honestly, this is an interesting one in that I could have removed the actual smut and just had it fade to black, and it would still be an amusing little one-shot. But I wrote it because I wanted that smut, with the rest of it being the amusing circumstances I came up with to justify it(and the aftermath).
Anyways. This one is a true one-shot, I don't plan on doing more here. I might do more Fate/Kaleid, but it won't necessarily be connected to this one. Unless I change my mind, which I frequently do. Either way, thanks for reading, and I hope you enjoyed it.
