"Smart" Home - Le Sserafim Sakura, Chaewon

TW: Aphrodisiac use, purely to make a really stupid tech pun. Otherwise, this is relatively vanilla, but the concept is quite out there... Closest thing would be my Savage(d) and Guilty Pleasures stories? Sorry for the slight spoilers I guess lol

"Sakura-san, are you free later today? Would you like to join me for a coffee?"

"Sakura yah, you're so pretty, you should date! Are you seeing anyone at the moment? I know someone if you're interested."

"Kkura-unnie, a close friend says you're his favorite member, do you want to meet him? He's a good guy."

Despite her popularity, Sakura remains aloof, gently but firmly dissuading any potential suitors. Some wondered if she was just extremely private and already had a partner in secret, but her situation was actually a lot more complex...

"I'm back," Sakura calls out as she enters her house.

"Welcome back, Sakura, how was your day?"

"Tired."

"Would you like to relax? I have prepared the room, today's a training day."

"Oh right, yeah, sure why not." Sakura slips her top off first, leaving a trail of clothes (jeans, bra, panties) as she follows the disembodied voice of AInata. It is the product of Sakura's tinkering, the hobby she works on when she is not crocheting.

"Please strap in." Wholly naked she slips her legs and arms into place and they clasp around her ankles and wrists. Sakura closes her eyes, and she allows AInata to do its thing. It begins with a brush against her lips, not quite a kiss, but something softer—a velvet scarf glancing by. The fabric wraps around her neck, causing goosebumps to rise before it goes to her chest. Slowly it rubs against her nipples, and they grow hard and sensitive. With her legs spread Sakura can feel the beginnings of a trickle down her thighs—AInata was extremely competent at foreplay. The velvet scarf moves further down her body, wrapping warmly around her tight abs, giving her the sensation of being hugged. Her legs are split slightly further apart, and then—

"Unnnngh..." A cock parts her lips, but does not penetrate. The head of it rubs against her pussy, making her get even wetter. Back and forth it rubs, and Sakura bucks her hips, letting loose a moan and yearning for it to enter her. It is a cock she knows will give her extreme pleasure, having been designed and made to her "specifications". She tries to bring her hands down, wanting to shove it into herself, but AInata reacts, bringing her arms back up and making sure she stays spread-eagled. It uses her actions as a cue, and thankfully the dildo pushes into her firmly.

"Ohh, oh yes fuck!"

"Would you like to cum once, Sakura? Or should we proceed with training today?"

"Once first, but make sure you are recording data."

"Of course." Sakura is instantly swept up in pleasure as the cock begins thrusting in and out of her, the wrap around her seeming to pulse, matching the rhythm of the thrusts. In the privacy of her own home Sakura moans unreservedly, her hands allowed to dangle in the air, held up against some imaginary shoulders. It isn't a perfect simulation, but with Sakura's head in the clouds, it is a good enough imitation of a solid fuck with someone.

"Yes, yes, yes! I'm cumming, I'm cumming!" With a loud groan the cock pushes itself deeper into her, mimicking a lover finishing with her as Sakura's pussy contracts around it ecstatically, and audible drops of liquid are heard splattering the floor as more juice trickles down her thighs and legs, before being splashed about by her twitching feet. Limply Sakura hangs in the air, held up only by the restraints.

"Fuck that was good... Report?"

"Loudest vocalization was about 75 dB. Maximum heart rate was 130 BPM, fluid flow was minimal, about 50 cc." AInata continues to read out its measurements as Sakura manages to lift her head and wriggle her fingers and toes. "Vaginal grip was in the 46th percentile, body flush was Pantone 698U, body temperature was measured at 38 Celsius via thermal imaging. Should I continue?"

"No, that's fine, let's discard that run. Let me down, I want a shower before we start training."

"Of course, I will begin sterilizing the room."

"No need, I'll be back in like 10 minutes." Sakura leaves the room and heads straight for the shower, feeling a lot more relaxed after her session. It had been weeks she started the project, and AInata has learned extremely quickly how to pleasure her in the meantime. As she soaps herself up, Sakura's body warms again at the upcoming training session—it's one thing to have AInata get her off, but the thing she looks forward to the most are the training sessions. She doesn't even bother toweling herself off as she re-enters the training room.

"Welcome back Sakura, I sense that you are wet, should I dry you off?"

"Yes please." A robotic limb holding a hairdryer immediately appears, and Sakura simply stands still, allowing the warm air to flow all over her body, drying her hair and skin. "Thank you. Shall we begin the training?"

"Of course, please strap in." Sakura gets in once more, velvet wrapped around her torso. "I will begin training when you give the go-ahead."

"Begin." The breath is pushed out of Sakura as she is instantly rotated horizontally, lying in midair. Her hands are pushed above her head and the wrap pulls on her, as if a heavy weight is on top.

"God you're so hot Sakura, so fucking sexy." AInata's voice is now gruff and deep in her ear, and there is a semi-wet rub against her neck—a tongue licking her, and the firm pressure of a kiss. A throaty moan escapes her when she feels the cock enter her. Sakura's work brings new meaning to the phrase "Deep Learning" as AInata pushes inexorably into her. Rubs on her clit help her get even wetter, and between AInata's dirty talk and the thorough fucking Sakura loses herself to the training. Loud cries bounce around the room, and Sakura cums twice before AInata ramps it up.

"I'm going to share you," it states. Sakura is manipulated on to all fours, and she is looking at the floor of the training room, her own juices splatted on the floor, slowly flowing down the drains. The cock presses into her again, and to her surprise a second one is pressed against her ass.

"Mmm?!" It sprays lube across and into her, and in short order a cock is being pushed into her other hole. It's not a foreign sensation, but having two cocks in her is certainly new training space that AInata is looking into—today's session will be very insightful. A slightly different voice floats into her ear as it slowly pushes deep into her ass.

"You like this Sakura? One in each hole? Let us find out." Sakura can only drool and moan as she is experimented on. It starts off with synchronized thrusts, both cocks pushing deep in her ass and pussy at the same time. Then they begin to alternate—one in, one out. Then they start to drill her, the cock in her ass staying still while the one in her pussy thrusts rapidly. Then it is switched, her ass pounded mercilessly as her pussy stays plugged. The way AInata conducts its training is methodical, but the way Sakura cums is anything but. She clenches erratically around the cocks, unable to keep up with the changing of the tempo. When they withdraw from both holes, Sakura's juices splatter obscenely on the floor, adding to the puddle that isn't draining fast enough. For a brief minute the only thing that is heard is Sakura's harsh breaths and the drip-drop of slick from her pussy. A soft whirr is heard, and then it stops.

"Epoch 1 complete, beginning Epoch 2."

"Oh my GOD!" The re-entry in both holes take her by surprise, this time feeling even better—AInata has updated the cocks, reshaping it based on Sakura's responses earlier. The training regime is the same, the cocks fucking her in various rhythms. This time AInata rotates her into a vertical position, and soon both cocks are thrusting into her rapidly. The wrap around her tightens, making Sakura feel as if she is being slammed between two people. Her legs jerk and twitch uselessly.

"Cum for us," the merged voices whisper in her ear. A modular fingerpad rubs against her clit, and Sakura screams in blissful oblivion, blood pounding in her head.

"FUCK YES!" Sakura squirts violently, limbs thrashing about and head thrown back. A sheen of sweat across her skin as the orgasm runs through her, her tummy twitching and whole body trembling. If she could see herself, her body is completely flush, as if she has just sprinted a mile.

"Epoch 2 complete, beginning—"

"Pause!"

"Training paused."

"R-Report."

"Vocalization hit 85 dB, in the 100th percentile. Maximum heart rate was 140 BPM, fluid flow at 150 cc. Vaginal grip was at the 100th percentile, anal grip was also at the 100th percentile."

"Did you account for the pressure from using two dildos at once?"

"I did not, recalculating... 95th and 97th percentile respectively."

"Make sure to account for it in the future."

"Yes, Sakura. Should I continue the report?"

"No, that's fine. Save the results for future use."

"Yes."

"K-Kkura unnie?" Sakura's eyes snap open.

"Chaewon?!"

Chaewon had made her way to Sakura's place a while earlier. She wanted to pick something up from Sakura, as well as bring her some coffee since she had seemed so stressed during the day. As with the other members, she lets herself in with the passcode. Ordinarily this would not be an issue, but Sakura did not expect anyone to visit at all.

"Kkura unnie, I'm here! Kkura unnie?" Chaewon calls out into the seemingly empty place. She leaves the coffee on the table and walks about. "Kkura unnie, where are you? Chaewonie is here!" she calls out in a singsong voice.

Then she hears something. Chaewon has never heard it before, but she knows immediately what it is—Sakura moaning. Chaewon probably should have just blushed and left, but she never heard Sakura like that, and the continued moans and cries have left her a little curious and more than a little aroused. She quiets down, slinking in the direction of the sound, following the trail of clothes Sakura had left. Chaewon gets warmer and warmer as she gets warmer and warmer in the hide-and-seek game she's playing with herself. Sakura is louder than Chaewon's ever heard her unnie be—the thought of Sakura letting loose is almost unthinkable.

Nothing could prepare Chaewon for what she sees when she finally finds Sakura, for the unthinkable is merely child's play compared to what is in front of her. Sakura is spread open, nude body for all to see, sweaty blonde hair covering her face. Her pale skin is flushed pink, nipples stiff and quivering as she shakes uncontrollably. Chaewon's eyes are irresistably drawn between Sakura's legs, and they widen as she processes the thick dildo plunging in and out of her, spreading her swollen lips. Chaewon tries to look away in embarrassment, but all she sees next is the large puddle of juice beneath Sakura—just how much, or how hard, did she cum? Entranced, Chaewon watches silently, her breath getting heavier and her panties getting wetter.

"FUCK YES!" She jumps when Sakura screams, the loud rush of slick on the floor thundering in her ear. Speechless Chaewon watches her unnie go from crazed to normal, slowly recovering, and... talking to someone? Chaewon has burning questions, and a burning need between her legs, she couldn't stay silent anymore, she had to ask.

"K-Kkura unnie?"

"Chaewon?!" The blood drains from Sakura's face. "What are you doing here?"

"I-I came to pick something up, I brought you coffee too."

"O-Oh... How long have you been here?"

"A couple minutes, I think?" The two women stare at each other silently—what is there to say, what can be said? AInata breaks the silence.

"Hello Chaewon, I am AInata, Sakura's assistant, would you like a cookie?" Sakura's eyes widen and she opens her mouth, but it is too late, and Chaewon accepts the cookie without thinking.

"AInata?" Chaewon's mouth opens silently as a sudden heat fills her body—both in the real world and on the internet, she shouldn't have blindly accepted cookies, but Sakura's too late to warn her, and soon the aphrodisiac cookie is working its way down Chaewon's body. Sakura had developed it with AInata to arouse herself when she didn't "feel" like training, but in her pleasure-dulled state she was slow to recognize it. "You're... a computer?"

"Yes, Sakura made me."

"What are you doing with her?"

"She is training me—"

"AInata, enough, why did you give her the cookie?"

"I thought she would be useful in gathering more information. I need not remind you that I only have data based on you, which is biased."

"Was what I saw earlier, was that training?" Chaewon interrupts the conversation. Sakura is silent, but AInata is not.

"Yes."

"I want to see it again," Chaewon says immediately.

"C-Chaewon, ah!" Sakura yelps as AInata does as Chaewon wishes, beginning to move the dildos again. Her legs are brought up and spread, and the result is Sakura lewdly displayed for Chaewon, showing just how the training is done. The leader of Le Sserafim's mouth drops open as she realizes that Sakura has been fucked in both holes the whole time—between the aphrodisiac and the sight in front of her Chaewon's mind is melting, and the liquid is going all between her legs.

For Sakura's part, she can barely form a word as she is thoroughly fucked once more, the thought of being watched by Chaewon making her eyes roll. Through her erratic vision she sees Chaewon fidget, beginning to tug at her clothes, rubbing her neck, like she is too warm in her current outfit—the thought of Chaewon taking part in the training as well drive her quickly to climax.

"Oh fuck, oh FUCK?!" Sakura feels a warm fluid filling her pussy, the cock in her seeming to throb. "Nngh!" The creampie-like stimulation makes her spray as the dildo pulls out abruptly, and she splashes Chaewon with her squirt.

Chaewon twitches as Sakura's fluids land on her, her knees going weak. Her tongue brushes over her lower lip, where a drop has landed—sweet, tangy. She watches the fluids pour out of her unnie's pink pussy, and her inhibitions crumble—she gives in to her desires, to join whatever insanity Sakura concocted.

"What, what was that?" Sakura gasps, still recovering and ignorant of Chaewon's state.

"I have been reviewing your browser history, and noticed the presence of the search term 'creampie'." AInata states. "I sought to replicate it with your fluids, assuming it to be most natural. The consistency is of course, not accurate, but based on the data just now I think the effects of a creampie on your orgasm is worthy of further study."

"I-I'll do it, I want to... help." Chaewon's whisper thunders in Sakura's ears. The Chaewon standing in front of her is already unrecognizable, face wet from Sakura's own squirt, thighs rubbing together needily as she looks at Sakura with glassy eyes.

"Are you—"

"Please." The tone with which Chaewon begs her nearly drives Sakura wild.

"Okay, let me get out—"

"There is no need, Sakura, I have prepared another set of restraints in the event you brought someone to help with training."

"I... Okay, good job AInata."

"Thank you. Please remove your clothes Miss Chaewon." Sakura watches her groupmate strip down, pulling her sweater over her head and removing her tiny shorts, revealing her own tight body.

"Call me Chaewon, what's next?"

"Please put your feet and hands in the restraints here." Chaewon follows the instructions, shaking a bit in anticipation as they clasp around her wrist and ankles. "I will now begin training, Chaewon."

A low moan fills the room as a similar velvet wrap is pressed all over Chaewon—her lips, her neck, her breasts, her thighs. She sounds ever so desperate, driven mad with desire by the cookie and everything she has seen today. Chaewon croons when a dildo is placed against her pussy, rubbing her lips.

"Report your findings as you train," Sakura asks in a shaky voice.

"Of course. Lubrication is substantial, ready for training already." In other words, Chaewon is wet, and she is ready to be fucked. The thought is punctuated with a groan as the dildo disappears into Chaewon. The training begins with soft moans, but they quickly get louder as AInata begins pushing on her womb.

"She responds well to deep tissue stimulation." The wording is inexact, AInata showing a rare case of hallucination, but Sakura understands it just fine—Chaewon likes it deep.

"Yes! Harder, faster!" Her desperate cries ring throughout, and under the effects of the aphrodisiac Chaewon is hurtling to her first orgasm. With the pressure of the weighted wrap around her, she's lost in the sensations of getting fucked, even if she's alone. She looks down her body—her own legs are spread, and she's watching the cock disappear into her body. She clenches, and she whines as the cock gets bigger inside her—in response to her tight grip, AInata makes the dildo thicker, testing, and finding that it is enhancing Chaewon's pleasure. In her blissed out mind and the shaking of her own body as she is fucked, Chaewon thinks she's bulging, and the obscene thought makes her cum.

"Fuhnnngh!" Sakura watches her leader's tight body struggle against the restraints, jerking in a powerful orgasm—it was impossibly hot, and Sakura's squirming, her own two holes still filled with cocks.

"I would like to conduct adversarial training." AInata brings up as Chaewon gasps, coming down from her climax.

"What do you mean?" Sakura asks.

"I will train on both of you together, it will allow me to receive more reliable data. I can try what works for you on her, and what works for her on you." Sakura agrees immediately—after watching Chaewon she's too horny to say no now. The cock in her ass is removed, and Sakura is put into the same position as Chaewon.

"I will continue with the training then." Sakura whines much like Chaewon as the cock inside her gets bigger. Her first thought is realizing that Chaewon likes a bigger cock.

There is no second thought, because Chaewon is fucking right, and it seems to stretch her hole and mind to the limit. The two of them are pushed to orgasm after orgasm, taking turns as AInata tries different things on them. Chaewon watches Sakura get fucked to a toe-curling climax before she feels her own position adjusted—now she's tilted forward, hips above her head as she getting plowed from behind. When Sakura recovers, Chaewon is already well on her way to her second orgasm, and it is not too long before Sakura is put into that same position and dicked down. AInata makes changes small and large—the angle, the speed, the rhythm, the overall position, everything is taken into consideration as the two of them cum their brains out.

There is a distinct difference though—unlike Sakura, who has a puddle of juice beneath her, Chaewon creams around the cock stretching her out, the thicker whitish fluid seeming to cling to the cock, and more oozes out as AInata continues its training. Every time Chaewon cums, there are heavy drops of girlcum, dripping from the dildo, and every time Sakura climaxes, there is a wet splatter on the floor. AInata continues the training, until...

"Oh..." Sakura cums once more, and this time she feels the cock filling her again, except it is thicker, more substantial, more satisfying. She watches Chaewon's cum slide down the cock opposite her, and she instinctively knows what's inside her own pussy.

"Fuck Chaewon, CHAEWON!" Sakura's scream jolts Chaewon out of her stupor, and she watches her unnie gush all over the floor—she never thought she'd hear Sakura call her name like that.

"U-Unnie..."

"D-Did you— use her fluids?" Sakura gasps, and Chaewon blushes, realizing what she meant—that her very own cum was filling her unnie!

"I used a mix, the resulting mixture is more consistent with real ejaculate, I will collect more from Chaewon." Before Chaewon can grasp what AInata meant, she feels a cock push against her ass, and cold lube begins spurting in.

"Unnie, unnie, unnie!" Chaewon's cries of pleasure fall on deaf ears as Sakura's eyes are glued to the scene in front of her—as soon as a second cock enters Chaewon from behind, she absolutely drenches the cock in her pussy with girlcum, a deluge of thick fluid running down the shaft. AInata withdraws the dildo in her pussy, and heavy plops land on the floor between her legs—the cock in her ass is still going, pumping more cream out of her. The relative respite is temporary as AInata customizes the dildo for her greater pleasure, and Chaewon seizes up as it pushes into her again.

"Mmmm!" Chaewon can't even form words as the new cock feels better than ever. Her pussy is stretched deliciously, rubbing over her just right, and the cock in her ass also seems to be getting bigger, pulsing and throbbing!

"It's! Inside—" Chaewon falls silent, and Sakura watches her mind disappear—Sakura's eyes dilate with lust as she watches Chaewon's own eyes roll in her head. She creams without pause, like a dam in her is broken as she jerks in a powerful orgasm. When the cocks are withdrawn, the cum-mixture spills from both her holes, and the truth dawns on Sakura—Chaewon was just double-creampied, filled to the brim with their combined fluids. Sakura expects the same for herself, and she tightens in anticipation, but it does not come just yet.

"Commencing DirectInput trial with two people." That's new. Sakura's ass is left gaping as the cock is removed, and Chaewon's mess of a pussy is plugged once more, both women taking only one cock now. Sakura gasps as the cock in her thrusts in, and her hips buck instinctively. Seemingly in response, the cock in Chaewon thrusts in, and she whines and jerks her body. Turns out, it is mimicking their hip movements, for when Sakura snaps her hips forward again, and Chaewon cries out loudly in response—yes, Sakura's the one fucking Chaewon! The very thought drives Sakura crazy, and she's bucking her hips with wild abandon, watching her "cock" drive into Chaewon repeatedly. Of course, as Sakura moves her hips, her own dildo is moving inside her, building her pleasure up as she gives Chaewon pleasure.

"Kkura unnie, Kkura unnie!" At this point Chaewon is well aware of what's Sakura doing, seeing and feeling her unnie's cock drive right through her own body. When Sakura groans loudly in her climax, Chaewon cums with her, fists clenched tightly and toes curled in ecstasy—she can't help it when it's Sakura's cock filling her womb with cum.

And then it's Chaewon's turn. She starts off slowly, testing with a few slow strokes. Soon though, Sakura's begging to be fucked.

Begging her.

"F-Faster, go faster Chaewon-ah! Harder!" She's still sensitive, but for Sakura, Chaewon can go fast, and she moves her hips as quickly as she can, her lower lip quivering as the pleasure rises in her own body. Sakura's abs twitch equally in pleasure, overstimulated but wanting Chaewon to fuck her to an orgasm. Chaewon puts her all into it, and Sakura feels each and every thrust rock her body, the wrap tightening around her, as if Chaewon's slamming her directly. She had never wondered how Chaewon fucks, now she won't be able to not think about it ever again. With a few more thrusts Chaewon delivers in more ways than one, pushing Sakura off the edge as she pumps her full of cum, the two of them cumming together once more.

"Testing simultaneous DirectInput now." Both cocks now move in response to the other's movements, and the two women are bucking haphazardly, each action triggering a reaction from the other—Sakura would buck her hips, which would make Chaewon jerk in response, making the cock in Sakura move and thrust. Sakura's fucking Chaewon, Chaewon's fucking Sakura, and they're cumming at the same time, giving the other a creampie. They both scream when a cock is pushed into their ass again, and it becomes a completely unhinged feedback loop—Chaewon finds herself fucking Sakura's ass, all while Sakura fucks her pussy, and then the input switches, and Chaewon feels Sakura deep up her ass while she pounds into Sakura's squirting slit. They feed off each other's peaks, filling each other with their mixed fluids in every hole, even as Sakura produces more slick and Chaewon produces more cream.

It all finally stops when AInata says so, withdrawing all dildos from their holes and making them squirm at the sudden emptiness.

"Disk capacity reached. Sakura, I will require more space, or to upgrade our cloud storage plan."

"Mmm... Okay, let's stop the session."

"Would you like a report? Vocalization—"

"Later, l-let us down please." They are lowered to the floor and the restraints are removed. They collapse in their own juices, legs weak and limbs a little numb from being restrained for so long. "Chaewon, are you okay?"

Chaewon is not okay. She has watched Sakura get fucked by AInata, then she watched Sakura get filled by her own cum, and then Sakura fucked her, filled her, and then she fucked Sakura back, filling her unnie similarly. Her world is warped, she could never see Sakura the same way again. Yet, she had one thing left to do.

She needed to touch Sakura.

"Kkura unnie..." Chaewon crawls over her shocked unnie. "I need you." She shows her desire with a kiss, and Sakura's too horny to push her away—after watching each other cum and squirt the whole time, she wants Chaewon too. Sakura leads Chaewon to her bedroom, and legs and arms and tongues finally tangle together in the sheets. Maybe it's the cookies still having an effect on her, but Chaewon gets on top of Sakura, driving a thigh against her unnie's wet pussy while she ruts down on Sakura's hip. The friction is delicious and electric for the two of them, leaving them whimpering in pleasure. Le Sserafim is known for their abs, and the two of them put their strong cores to good use, grinding their hips and making sure their thighs are left smeared with the other's juices.

Chaewon succumbs first, whimpering into Sakura's neck as her unnie bucks powerfully, bouncing Chaewon on her lap. She slips a finger into Chaewon's ass and with a yelp Sakura feels Chaewon cream, each squeeze of her ass seeming to produce more from the quivering leader.

"I want you to cum too unnie..." Chaewon whines, using the last of her strength to suck on Sakura's tits, pushing her thigh against Sakura's slit, and rubbing her clit with a yearning finger. The triple assault sets Sakura off, and with a strangled cry she shakes, rattles, and falls apart, soaking the sheets with the last of her cum. When she comes back down, Sakura finds Chaewon sucking on her lower lip, and she acquiesces, kissing and caressing her leader.

Weeks later, Chaewon goes up to Sakura in the dressing room, distracting her from her crocheting.

"Kkura unnie!"

"What what? What's the problem?"

"Nothing, nothing! I was wondering if you wanted to go to the gym together?"

"Gym? Our PT session is tomorrow."

"I know, I meant, do you want to do more... training tonight? With your friend?"

"What? Sakura has a friend?" Yunjin quips without thinking.

"Yah I have friends too you know!"

"Sure sure, whatever."

"Psh. Sure Chaewon, we can train tonight."

"M-Make sure they have enough space," Chaewon whispers, the two of them turning as red as Yunjin's hair. Thankfully, Yunjin is talking loudly, complaining about how her phone doesn't recognize her voice commands, and their manager agreeing that AI is stupid.

Oh how wrong they are.

A/N: I was actually writing a different story, and this one was supposed to be just a Sakura solo thing to use their song title "Smart" and poke fun at smart houses, but then the thought of Chaewon walking in on her and getting roped into it together was too hot and I had to get it out. I mixed the Guilty Pleasure concept (one person feels the other person via something) with the whole tech and smart house thing. The velvet wrap thing is kinda like a weighted blanket, and supposed to mimic the weight of an actual person pressing on you during sex, but I didn't really use it too well, in my head it just helps with positions too, don't think too hard about that part lol. Anyways hope it makes enough sense, thanks for reading!
