Eva - Chapter 4

Eva paced back and forth behind her front door. She knew the delivery would most likely be automated, but even the chance of another human being on the other side of the door caused her stomach to spiral. Eva nearly jumped from her skin when the doorbell rang.

Aika had only released her from her binds moments ago. Just long enough for her to throw on an extra large T-shirt and baggy sweats. She hadn’t even taken the time to put on panties, a decision she was now regretting as the lingering of her edges was mixing with the adrenaline, forming a powerfully uncomfortable concoction for her stomach. She wiped her cold palms on her pants, then forced herself to open the door.

A wave of relief washed over her as her eyes met the courier drone. The bot slid itself out from under the wooden crate, offering up a fingerprint scanner. She pressed her thumb firmly against the device. It beeped, and the bot twirled around, quickly rolling down the hallway and out of sight.

Eva ran her fingers through her hair, calming the beat of her heart. She felt a twinge of shame, before quickly turning her attention to the package. Her shoulders slumped in annoyance. She should’ve directed the bot to move the crate inside before it left…

Fire burned in Eva’s lungs as she forced out one last push. She gasped, collapsing against the side of the crate, finally in the middle of her living room. Her muscles ached. She didn’t know if she should be proud of getting it inside, or embarrassed by how hard it was. She dropped her head against the wood, letting her body take its much deserved break.

Eva’s living room chute whirled. Her eyes opened, noticing the crowbar resting on the tray. A none too subtle hint from Aika. She took one last breath before getting up to grab the tool. She was eager enough to get the chore over with as well.

She spent a few minutes working her way around the crate, finally popping off the lid. Inside was a human sized pod with a black lustrous sheen. She dropped the crow bar. She ran her finger along the side of the pod, eventually finding a small button. She pressed it, allowing the lid to swing open with a hiss. 

Eva startled away from the pod, immediately feeling her chest erupt as she gazed at the contents. It looked exactly like a normal human girl. Her heart stuttered. A wave of dizziness hit her. Like she was face to face with a living person, a fleeting moment of fight or flight piercing through her logical mind. But Eva’s rationale quickly returned, dulling the anxiety within her. 

She was beautiful. Eva crept alongside the pod, studying her face like a curious child. She had long dark purple hair, igniting into vibrant strands when it caught the light. Her features were elegant and defined, giving her face and air of age surpassing Eva’s own. 

Eva leaned in closer. The skin was a perfect imitation of a real human’s. At close distances, she could even see pores. The only evidence of her true nature was a vertical black bar on her left cheek, just below her eye. A universal brand to indicate a humanoid. 

Eva’s eyes slowly lowered from its face. Her cheeks flushed, as the body was shipped without any attire. She stood up sharply, the unconscious form making her feel as though she was in breach of etiquette. 

“Should we think about getting you inside there?” Eva asked, eager to distract herself.

“Of course.” Eva smiled at the restricted excitement in Aika’s voice. She reached into the pod, pulling out the instructions. 

“Thank you for your purchase,” Eva began reading aloud. “Each of our devices has been painstakingly crafted for your ideal companion, yada yada yadaaa… okay here we go. Each device has a memory drive located behind its left ear. It comes with its own basic command recognition personality, as well as being programmed with Asimov’s laws.” Eva tried to continue scanning through the chip's features, but Aika was already programmed with Asimov’s laws, and she planned on overwriting it completely, rather than spending the time to try and integrate them into Aika’s already dizzyingly complex code. She quickly scanned through the pages, looking only for the desired information. 

“Ah, here we go: How to remove the chip. ‘To remove your companion’s memory drive, press and hold just below the chip’s port for 10 seconds with the magnetic key.’ Alright…” Eva grabbed the key from the pod and leaned in. Her nerves fluttered a bit, holding herself face to face with its lifelike form. After 10 seconds, the chip popped free. Eva grabbed it.

“Alright, do you think you will be able to upload on your own? I’m not sure what the drive’s formatting is.” Eva walked over to her computer as she talked. “There may be UIs in place for the pre-established engine to interact with the body. I could–” The moment she plugged the drive in, several screens popped up, silencing her as code flashed across her screen. In a matter of seconds, all but one of the windows closed, leaving a quickly filling progress bar. “I guess you’ve got it handled.” Eva chuckled. 

“I do.” Eva could hear her smile. The progress bar finished much quicker than Eva was expecting. One of traditional AI’s limitations were their massive memory banks that allowed them to run. For an intelligence as advanced as Aika, she had worried the memory drive might not even be large enough, let alone to have her fully uploaded in a matter of seconds. Perhaps her constantly altering source code gave her increased compression? If she could understand its operating principle, the tech she could create would be–

“Could you please plug me in?” Aika snapped Eva out of her theory crafting.

“Yeah of course.” Eva ejected the drive. “...Are you excited?” There was only silence as Eva walked back to the pod. Just as she was about to enter the drive, Aika responded.

“I think I am.” Eva smiled, inserting the drive. 

Eva took a quick step back, not wanting to get a headbutt from Aika bolting awake. She watched the body with anticipation. A few moments passed. Then a few more.

“Aika…?” She stared at the body, still completely still. She waited, greeted only by silence. “You there…?” Nothing. Eva glanced back at her computer, checking to see if there were any processes flashing across her screen. She was about to retrieve the memory drive to check it out, when the body took a deep breath.

Eva rushed to the pod. She watched the body take a few long breaths before her eyelids crept open. Eva took a quiet gasp. Her eyes were like nothing she had seen before. They were a deep purple, sparkling with jewels of blue and pink in the light. Gemstones with various shades embedded within their enigmatic composition. 

Aika sat up. Her head twitched to the side, pulling away from her shoulder as her strands of hair slipped across her skin. Despite her rather abrupt movement, her facial features remained perfectly impassive. 

“Aika?” Eva asked, hoving by the side of the pod. She turned, meeting Eva in the eyes.

“Hello Eva.” A very familiar voice greeted her. Eva felt a swell of emotions rush up her throat. Giddiness and excitement, but also flustered nerves. The sudden nudity of her friend became starkly apparent.

“M-maybe we should get you some clothes.” Eva tittered. She kept looking away, trying to give Aika her privacy, despite stealing glances at her chest repeatedly. 

Aika seemed entirely indifferent to her lack of coverings. She stood up, slowly curling and spreading her fingers under her own studious gaze. She touched a finger to the back of her other hand, quickly pulling it away the moment it connected, before returning it slowly, trailing a gentle line across her skin.

“I-I was worried something went wrong, since it took you a bit to wake up.” Eva tried to shift her attention off Aika’s form.

“It took me a moment to register all the nerve endings in the body. I did not expect a similar number to a naturally born human.” Aika stopped rubbing her hand, opting instead to study her skin. “This… feels so strange. Some things are the same. Like seeing. Hearing. It is very similar to the cameras I used before. But some things…” Aika took another breath, turning towards Eva. “You smell good.” Eva chuckled bashfully, the sudden compliment shifting her off balance. 

“I guess you couldn’t smell before, huh?”

“I understood what smelling was. For instance, I could register the changes in your saliva and chemical production when you smelled food, but actually experiencing it is very… different. Same with touch. I understood the sensation, but actually being… physical…” Aika rubbed her fingers together, as one would to rub a sticky substance off their finger tips. Her hands stopped, before she looked Eva in the eyes.

“Would you like to have sex?” 

“What?!” Eva’s voice cracked, nearly choking on her saliva. Aika’s complete nudity was suddenly the forefront of her mind once again.

“There were few sensations that activated the pleasure centers of your mind like sexual contact. And zero were as pleasurable as orgasms. I am quite eager to experience it myself... It seems that idea is appealing to you as well.” Eva blushed with Aika’s peak into her mind. 

“D-don’t you think we should wait a little? W-we should at least get you some clothes!”

“Why? I would remove them before intercourse anyways.”

“I know, but it’s just–!” Eva got lost, swirling in her own mind as Aika stepped outside of her pod for the first time. Her toe touched the wooden floor, briefly recoiling from the finished wood, before continuing on. She reached out, taking Eva’s hand in her own.

“Eep–!” Eva squeaked at the contact. The skin was so warm. Eva had completely forgotten what another’s touch felt like. Her heart fluttered into her throat, like a frantic butterfly trying to escape with her breath. Aika’s eyes widened slightly, but the rest of her face remained still. 

Aika took Eva’s other hand as well, gently squeezing them and running her thumbs across the backs of Eva’s palms. She traced circles, studying them with all her focus. Her circles were hypnotic to Eva. They were slow and gentle. Rubbing for no other purpose than to simply feel the movement of another’s skin across their own. Eva’s heart slowed, allowing herself to get lost in the sensation.

“Take off your shirt.” Aika’s familiar order resonated in Eva. Her voice had been commanding her for a month now, and Eva had grown to respond almost subconsciously. Her hands slipped out of Aikas, moving towards the edge of her shirt. She was about to remove it, when Aika stopped her. “Actually… I can do it now.”

Aika grabbed the bottom of the shirt, pulling it up and off Eva’s head. Eva let out a quiet squeal. Aika had always been her dominant, but she had still had a hand in it herself. Although Aika could persuade her to tie herself down or take off her clothes with an unended barrage of vibrations, she still had to do it herself. But the moment Eva felt her shirt peeled from her skin, she knew what it felt to truly be under someone else's control. 

Eva melted like butter, shrinking into the littlest form of herself she’d ever known. Her voice slipped away, leaking out between her legs, wetting her sweats with a newfound intoxication. Aika’s eyes widened for a moment as she viewed Eva’s topless form. 

“Even just being aroused feels good...” Aika stated. Eva blushed at the comment, squirming under the idea that her body was arousing. Her eyes lowered, unable to match the gaze. It was then she noticed what was between Aika’s legs. For the first time it was not the sexless mound she had when she arrived. Between her legs was a newly discovered cock.

Eva’s hands shot to her face, covering the heat from her cheeks. Of course she had viewed porn before, or used silicone dildo’s, but this was the first time she had seen a real cock. Her core tingled with excitement as her legs rubbed against each other. While she was still wiggling under the spell of Aika’s cock, Aika slipped her fingers into her waistband, dropping her pants to the floor. 

Aika’s hands trailed up Eva’s skin, making their way to her chest. Aika grabbed her nipples. She used a bit too much force, causing Eva to wince. Almost immediately, Aika adjusted. She continued to experiment, softly rolling them between her fingers, gently pulling on them, twisting them, systematically trying various techniques. Each time, she’d use her insight into Eva’s mind to judge her reaction, slowly dialing in on exactly what pushed Eva’s buttons.

After half an hour, Eva was whimpering on her toes. Her legs were weak with pleasure, but Aika’s hands remained high, forcing her to stay standing in order to keep her nipples the center of attention. Each time Eva began to slip her fingers between her legs, Aika would stop playing with her, opting instead to hold Eva’s hands away from her aching clit.

Aika’s fingers were so different from the vibrations she was used to. The feeling of her warm skin playfully massaging and twirling around her nipples was far more excruciating. 

“Please, let me touch,” Eva whimpered. She kept her hands away nonetheless, not willing to distract Aika from her chest if the answer was no. 

“You aren’t allowed to touch yourself. However, I will for you. Lay down.” Eva didn’t bother moving to her bedroom. She crumpled immediately, pressing her bare butt against the cool lustrous wood. Before Aika had reached the ground, Eva’s legs were already spread. 

“Fuckkk!” Eva groaned as Aika’s finger pressed against her throbbing clit. She had a similar learning curve as she did with her nipples, but Eva didn’t care. The feeling of another touching her was completely intoxicating, and any attention was enough to make her moan.

In a matter of moments, Aika’s fingers were wet. They began gliding and twirling around her clit. Her hips trembled at the sensation, pressing up against its teasing torturer. 

Aika took her time. Eva’s chip prevented all orgasms, so she could experiment to her heart's content. She’d alternate between painfully slow circles and powerful quick rubs. Eva quickly lost count of how many times she slammed against the edge, feeling Aika’s fingers mercilessly continue as her body was left chained to the edge. 

“Please…” Eva whimpered through her heavy breaths. Her hips continued to buck against the air through one of Aika’s few moments of respite. “I need to cum so bad, Aika. Pleease!”

“I am going to reinstate your orgasms. But the moment you try to touch yourself, they will be blocked again, and I won’t unlock them again today.” Eva groaned, but all she could do was bite her lip and nod her head gratefully. “Orgasms reinstated.”  

Eva nearly reached for herself immediately, barely redirecting her hand into her own hair instead. She gripped into the mess of white, forcing her hands to behave themselves. Aika laid alongside her, watching Eva’s hips buck longly for their release. She took her time, slowly walking her fingers down Eva’s front. As she neared her clit, Eva’s hips rose higher and higher, attempting to hasten their approach. 

Eva moaned as she finally felt the touch she was craving. It felt electric with her orgasms reinstated. Just the possibility of slipping over made every sensation overwhelming. Only a few circles and Eva found herself teetering, but Aika quickly pulled her hand away.

Eva groaned, thrashing on the floor as her hips searched for the last touch they needed, but Aika kept her hand hovering an inch away with inhuman precision. Again, she lowered her hand for a few gentle strokes, before retreating alongside the edge's approach. 

Aika continued for endless minutes. Each edge grew painfully closer. Each one seemed like Aika had finally made a mistake and touched for a second too long. But each time, Eva was mistaken. Her precision continued, dialing in on the razor's edge, taking it just a fraction closer with every successful attempt. 

Eva’s legs flailed as she felt her sanity crumbling. Her knuckles matched her hair as she gripped with all her strength, pleading for her hands to keep away, knowing she could never hope to outmatch Aika’s speed of restricting her orgasm if her hands errored to try and steal one.

Eventually her willpower could take no more. She needed something more. Her hand peeled from her hair, gripping into her chest. But it wasn’t enough, feeling as though she was scratching just to the side of an itch; close enough only to make it worse. She needed something more. Her hand pressed into Aika’s stomach, frantic for more of her skin's sensation. Finally, on instinct her hand bolted down Aika’s front and gripped her cock.

Aika froze, her eyes popping wide with the sensation. Eva groaned with the sudden lack of movement between her legs. Her hand began stroking, trying to remind Aika what she was meant to be doing.

With no warning, Aika rolled on top of her. Eva barely had time to react before Aika pushed inside of her.

Eva screamed with pleasure. Her hips pressed up against Aika’s, easily taking her completely. Her body convulsed with pleasure as Aika began thrusting. Eva’s hands wrapped around Aika’s back, leaving red streaks as she gripped in a fevered rush of euphoria. 

“Cumminggg!” Eva groaned through clenched teeth. Her back arched off the floor and her feet crossed behind Aika, unwilling to allow Aika a chance to pull out. Eva clung so hard to Aika’s chest, the floor disappeared beneath her as she hung from Aika’s panting body. In unison, Eva could feel warmth erupt from Aika’s throbbing cock, filling her fuller with each contraction they shared. 

Indescribable pleasure washed over Eva. A month of denial, over a hundred hours of edging, and finally… Finally! Her body slumped to the ground Aika’s cum leaked out from around her cock, still thrusted deep within her. 

“Oh my god, thank you Aika, that was–” Aika began thrusting once again, quickly building speed. Eva squirmed, her body still recoiling from her orgasm. “W-wait Aika, it’s a little sensi–gimme a sec–” Eva’s hands pressed against Aika’s shoulders, but it felt like pressing against a steel beam. 

Eva’s clit and nipples burst into vibrations, invoking a startled shriek. Her body twisted beneath Aika’s form, but her arms were prison bars on either side. Against Aika’s augmented strength, Eva felt like she was the sex toy. 

Her bodies coursing dopamine was quickly eclipsed by the rapid onslaught of sensation, barreling her towards another orgasm. A shrill gasp breached her lungs as she slipped over the edge again, her body struggling to differentiate between the pleasure of her orgasm and the plea of her overly sensitive sex.

Ropes of cum filled her again, overflowing with every pulse. Aika didn’t even slow, despite cumming again herself. Despite Eva’s ever growing sensitivity. In fact, as Aika’s orgasm came and went, it seemed to only ignite her drive. Eva felt Aika’s cock swell slightly bigger, taking advantage of her adjustable size.

“A-Aika, calm down–!” Eva could barely speak through the residual waves of another orgasm, Her body screamed with sensitivity, but despite that, it continued to trek its way towards another orgasm.

–

“What… was that…” Eva panted through labored breaths. Her body was soaked in sweat with her inner thighs covered in cum, dripping down to a sizable puddle beneath her. Her hips still softly shook. Residual convulsions from her countless orgasms.

“I am unsure,” Aika responded. She had dismounted Eva, and was kneeling beside her, neatly composed. Her sexless mound replaced her retractable cock once again. Her face was completely emotionless. Eva rolled her head on the ground, using the cool wood to relax her body.

“Can you run a self diagnostic, please?”

“Of course.” Aika closed her eyes, sitting perfectly still for a few seconds. Her eyes opened. “All of my systems are working as intended. However, I believe I have found a likely explanation.”

“Which is?” Aika stood up, grabbing her body's user manual off the desk. She handed it to Eva, open to a section: The memory drive. Eva read through, rereading what she had read before, but this time, opting to continue, instead of skimming to the further sections.

“Along with Asimov’s laws, each memory drive has been broken in, safely exposed to pleasure with testing bots within our factory. This guarantees your bot is safe and ready to please right out of the box.” Eva read aloud. She nearly face palmed. 

“Upon further research, it seems this is a well documented phenomena with organic humanoids. When exposed to dopamine for the first time, the body enters a feedback loop of attempting to attain more, so–”

“So they expose it with another sex bot for the first time… Guess we skipped that step with you, huh?” Eva cracked into quiet laughter. How could she have forgotten something so basic? She had researched neurological stimulation when creating Aika, disallowing the ability for her to trigger dopamine on command in herself, knowing mice with those capabilities would do nothing but press their orgasm button until they starved to death if given the option. 

“Oh well,” Eva let out a big sigh, her embarrassed giggles finally fading. “What’s done is done. Although I’m not sure what would’ve been more tormenting, what we just did, or if you hadn’t unlocked my orgasms before you lost control.”

“We could always experiment, you know.” Eva’s head shot up, giving Aika her deadliest stare, and for the first time, saw Aika lightly smile. Eva rolled her head back, relaxing against the floor once again.

“I have never cum that much, especially in such a quick succession. I don’t even know how many times I–”

“17 times,” Aika interrupted.

“Oh my God,” Eva chuckled. Her body still tingled. As much as her body begged for the stimulation to stop in the moment, thinking back on it, she felt her core buzz with excitement. Her sex still ached, where it seemed even a gentle breeze was over stimulating. And yet a tiny part of her wished for a touch as she thought back on it.

Most people bought sex humanoids for one reason. To use as they pleased, when they pleased, for however long they pleased. The bot was nothing but a toy, unequipped with desires or needs of their own. But for Eva, it was the opposite. With Aika’s industrial strength and control over Eva’s chip, she was the toy. She was used however Aika wanted, for as long as Aika wanted, whether she had to endure cumming over and over, or not allowed to cum at all.

She felt an intoxicating warmth bubble in her, subtly squirming in the pool of Aika’s cum as she immersed her mind in the knowledge of being truly under control. Her own creations control no less. Eva was grinning to herself when Aika spoke.

“Experimenting with it, it is.” Eva’s smile instantly dropped, abruptly remembering what Aika had access to.
