Spa Surprise

It was a fairly unassuming envelope. Simple, white, crisp letting and a stamp. Natalie’s name was hand written in black ink in the kind of immaculate lettering that let her know that this was not written by human hands.

She shuffled it into the rest of her mail, two bills and a flier for a free tune up with the purchase of some other body upgrades. She was curious about what the exact contents of the envelope was, but she knew what it was about. Beth had let her know to be looking for the invitation in the mail. This had to be it.

With the mail tossed onto the table, Natalie settled into her reading chair and tucked a strand of chestnut colored hair behind her ear, and pulled open the envelope. The invitation inside was simple, so simple in fact that Natalie couldn’t help but bark a single, small laugh.

9:00am Holman Spa and Detailing Saturday.

Efficient and effective. It was everything Natalie needed to know, and with plenty of time to prepare. She had to wait a week, but that was likely to allow the other guests time to clear their schedule and take care of anything else. Likely to give Beth time to arrange some things as well. Which was fine, Natalie’s schedule was clear most days and she made her own schedule. So far there were no appointments for Saturday or Sunday, and with this invitation, she wouldn’t take on any clients for those days either. This would honestly be a lovely way to break up the monotony of just plugging herself in and waiting for Monday morning.

Natalie shoved herself out of the chair and began to move to her room. Her black leather jacket and grey shirt came off quickly. Her well worn chuck taylors slipped off and were unceremoniously kicked across the room and joined by her jeans a moment later. The advantage to being an android was that you only really needed to do laundry when something truly awful happened to you, but Natalie gathered up her clothes and tossed them into a hamper.

Reminders were set on her built in calendar. Friday, Laundromat. Saturday, party. Sunday Recover. Perfect.

Natalie huffed a little, and then flopped into bed. She closed her eyes and bid the small connection port in the side of her neck to open. Where there was once pristine skin, now an opening formed and revealed the hard, dull grey plastic within. She wasn’t going to bother looking for her charging cable, she was vaguely aware of where she had left it. Her hand shot out, flopping and probing along her side table a few times before she found it.

She brought it to her neck, plugged it in, and the world faded into scrolling code and darkness. All that remained a moment later was a countdown timer to when she needed to reactivate and get dressed for work. Just the same as the night before, and tomorrow night, and the night after that..until saturday.

That brought a smile.

Kyla’s eyes fluttered open, right on time, greeted by the dim morning light. Or at least as much of it as could be filtered through the blinds. Her soft green eyes were partially obscured by the ruffle of red hair that had fallen across her face. All too soon a hand found its way to the power cable jutting from an open port in her chest, but not before a small playful grope.

“Hands off, I'm a taken woman.” Kyla muttered, her voice thick with a groggy haze. It was a playful thing, she was actually fully aware of what was happening around her, even as her systems continued to boot.

“Yeah, by me, you dweeb.”

Evie’s voice came from the other side of the bed, followed by a brief kiss on the cheek. Kyla smiled at that and turned to try and reciprocate, only to find herself looking at the back of her girlfriend as she slipped off the bed. The subtle whispers of seams where two panels of artificial flesh met criss crossed her back. They were familiar to Kyla.

The small whine from the bed turned Evie’s head back to Kyla. Dark hair with a single blue streak on one side of her head framed Evie’s face. As soon as she saw Kyla she rolled her eyes but couldn’t help but smile.

Her lover was pointing at her lips and making a cute little pout. Evie crawled back in bed and obliged one more kiss, and one more grope. After that, the pair was out of bed and getting dressed for the day. Kyla was preparing herself to sneak up on Evie and grab her from behind, maybe with the element of surprise she could drag the woman giggling back into bed. The obnoxious squeak of their mail flap interrupted what her OS planned.

Evie was there first, scooping up the junk mail and sifting through it before her eyes lit up. Kyla appeared in the doorway, she had managed to get a skirt and bra on and was working to button up a blouse. Evie’s delighted expression earned a raised eyebrow from Kyla. A moment later her optics flicked to the envelope that had been torn open, and the simple card in Evie’s hands. Then she too lit up.

“Saturday.” Evie said.

“Saturday.” Kyla confirmed.

Being a hostess wasn’t exactly in Beth’s nature. She was used to being a participant, but how could she pass up the opportunity to gather her friends in one place and party hard. An unexpected windfall of cash provided the perfect opportunity as well.

Holman’s Spa and Detailing, just Holmans to most of the people who utilized their services, was a small and unassuming building. Little more than a small office building or clinic. A single receptionist in a fairly sterile lobby with a trickling and serene water feature to one side and far too many living indoor plants. To one side of the desk loomed a single door.

Anyone who walked in off the streets would be greeted and have their questions answered. If they didn’t belong there, they were turned away. And who belonged there? It was by appointment only, which kept out most people who didn’t know what they were in for.

The rest of the clientele made it through the door and from there, around a small hallway, past the office manager's room, and down the stairs.

Holmans basement was the real spa. Which stretched the meaning of spa a little more than most people might expect. Human’s imagine natural hot springs with open air pools looking to the skies above, bamboo gardens and native american flute music. Or warm earthy tones on the walls to a hallway that led to massage rooms.

Holmans looked more like a club. A massive central space with a small stage at one end. The speakers were a permanent fixture there. A DJ could easily place their equipment there and hold something akin to a rave, though those rarely happened. More often than not it was simply used to play soft music. Nothing like a spa, though nothing like a rave or dance party either. Deep bassy beats and enough rhythm to get the body moving in just the right way.

The outer rim of the roughly rounded room were doors, open, welcoming, and inviting. Private spaces for lovers to retreat if they wanted, but not today.

Beth was in the center of the room. The lights were at their fullest brightness and even then it still had a moody dimness to it. Fine for her event, less ideal for coordinating the set up. The light, dim as it might be seemed to be fully absorbed by her caramel colored skin, even as it shimmered on her black hair.

In her hands she was holding a clipboard with hastily scrawled notes from herself, to herself. Many of the items were checked off, some had other notes, some were simply there. Around her, the equally robotic crew was setting up for the party she had arranged. By tomorrow morning this entire place would be filled with the two dozen or so robotic men and women she had made contact with over the years. What better way to celebrate her friends than dragging them all into one place for some socializing.

She had made sure that all of them were warned well ahead of time about what, exactly, that meant.

She had laid out her plan well ahead of time. A soft start, pun fully intended, in the morning. Shake hands, introduce everyone to everyone else, and offer an hour or so to get everyone set up.

Her eyes darted over to the table across from her. Small vials filled with semi-viscous fluids were being slotted into a flower covered rack. Organized by brand and displayed invitingly. Next to it were more innocuous containers, each one labeled with the vendor and product name. All of them sported something suggestive. Soon the table was filled with a lovely display of artificial lubricants and options for cum.

She had had the option of flavors, but once she mentioned that this was going to be a robot only orgy, the concept of scents and flavors became somewhat moot. Those were usually human centered concerns, and there would be no one biological in the building on Saturday.

She carried on down her list, standing in the lowered “pit” at the center of the space. Soon she began to pace around, taking it all in, marking off what was done, what was in progress, and what wouldn’t be ready until the next morning. Her only hope was to get the majority of her list checked off before tomorrow so she might actually partake in the festivities.

The Saturday morning sunrise was as lovely as any other. Washing the morning haze in a subtle riot of colors. Once the heat from the sun slammed into the fog, everything cleared and to Beth’s relief, everything had gotten done the day before. The only thing she was waiting on now was-

“Hi there.”

The voice of a woman snapped her back from her track of running over the needed items..again. Tall, darker skin, and a frizzy afro on her head. The woman wore a polo shirt with the logo of Holman’s just over the right breast. Then in small wording just below it were the words “Technical crew.”

“Cynthia Mills. You must be Beth.”

The pair shook hands and continued on down the stairs to the event space.

“The work order just called for a technical crew for upkeep. Care to enlighten me on that.” Cynthia said as she reached the bottom of the steps.

With a dark stain crossing Beth’s face, she supposed it was a reasonable thing to ask. And she should be upfront.

“Well, we’re having a bit of a, uh, a sexually charged gathering here today.” Beth began.

“Robot orgy?” Cynthia said bluntly, lacking any and all judgement in her voice.

“Yeah.”

“Nice. I’m jealous. My professional programming will keep me from participating, but I’ll enjoy the show at least.” She ended with a wink.

Beth chuckled. “Well, the folks involved are probably going to like a bit of personal attention. Help with keeping them running, swapping parts if they want, and uh- w- well they probably want to be. You know…”

“Treated like a good little robot?”

“Yeah.”

“Sounds good. Not the first orgy I’ve worked honey, no need to be embarrassed.” Cynthia said.

With that out of the way, and a list of model numbers and types in hand, Cynthia picked out one of the empty rooms and began the arduous task of bringing in her crew. Two other women, a plethora of tools and technology, and two very study looking benches. Everything looked to be in place for them to set up a very effective mobile repair station.

Each of the benches were draped with surprisingly soft sheets and, much like you might find in any other conventional massage parlor, soft music and dimmed lights. It was an interesting choice, Beth thought, but Cynthia had done this before. Who was she to criticize a professional in their element?

The small chime from up the stairs and the giddy sound of voices trickling down the stairs let Beth know that the first of her guests had arrived. Even though she wasn’t specifically listening to the voices, and intentionally ignoring the broadcast signals from the units, she knew who this would be.

Natalie for sure, she was perpetually on time. No, she was perpetually early. She had probably arrived fifteen minutes ago and was simply waiting outside. Evie would be there too, showing up perfectly on time, which meant there was a good chance Kyla was there too. She supposed it really depended on where Kyla had spent the previous night. On her own, she would be late by at least a half an hour. If she and Evie had spent the night together, then certainly she was there too.

There were other voices too, some she recognized, some that were just lost in the cacophony of sounds. Some male, some female, some that were a little more challenging to pick out. Not that it mattered, Beth had rented out the spa for the next eight hours, there would be plenty of time to see everyone, and with any luck, everything.

Everyone was greeted the same way. Beth stood at the base of the stairs, smiling broadly with her hands folded behind her back. The strategically ripped jeans showing off just enough of the darker skin that they contained. Her tank top teased at her bosom and flagrantly showed her belly, as well as left her arms, and by proxy the spiraling tattoos, on display.

“Hey nice kicks.” Natalie mentioned as she reached the bottom of the stairs, Evie and Kyla in toe. Just as Beth had expected.

Both robotic women looked down at the Chuck Taylors on their feet and shared a quick giggle before hugging one another. The leather jacket Natalie wore creaking slightly from the embrace. Once it was broken Evie and Kyla were brought into a similar hug. There was a small line forming behind the trio, but that was alright. Beth was more than happy to make her announcement a few times.

“Charging stations over there in case you need to top off. Next to those are some canvas bags with tags, put your clothes in there for safe keeping. Mechanics on the left, and-” Beth explained, only to be interrupted by Kyla.

“Are those alternate sex modules?” The redheaded woman said as her green eyes literally sparkled. Kyla was off, making a beeline for the table where her toughest choice was about to be not if, but which one she should try first.

Natalie, meanwhile, was off to check in on the flowery display of lubricants, stopping first at the table arrayed with bags. Once there, her jacket came off, then her shirt and bra. Her jacket was bulky enough to take up a whole bag, everything else fit neatly into a second bag. Tied off, labeled, and stored, Natalie strode on. Unlike her robotic companions, Natalie looked perfectly human to the naked eye. No seam lines or obvious panels.

Beth and Evie watched her go, smiling after her as she practically skipped to the table before turning back to one another.

“Long time no see, you goober!” Evie said as she leaned in for a warm embrace.

“Yep, not since Marcella’s party, right?” Evie commented. She knew for a fact that it was true, as did Beth. The memories of a robot were tough to muddle.

“Wasn’t that the night you and I got caught making out in the cupboard because all the bedrooms were taken?” Evie said.

“Almost got caught.” Beth corrected.

“That’s not how I remember it. Because somehow Kate got pulled in there too.”

“Yeah but that wasn’t because we got caught.”

The pair had a small, silent standoff. Both squinting at one another as something in their operating systems double and then triple checked the memory logs from the event date. Each verified that their version was correct, but also that it wasn’t worth arguing about. So instead they each gently cracked a smile that devolved into a round of laughter and another tight hug.

“Once this is over. You and me need to catch up.” Evie said as she broke the embrace and trot along to catch up with Kyla. Once she caught up with her Beth could hear the gentle waft of their conversation.

“C’mon, let’s find a good one for you.” Their clothes came off as they walked. Each article reveals more of their naked, feminine bodies. Subtle but visible seam lines streaking across their bodies and marking access panels and pre-fabricated plates of synthetic skin.

Beth looked along after those three before turning back and being met with another group of androids, so she repeated the small introduction she had given the first three. She knew she would be saying those same things a lot for the next half an hour or so, which was alright with her. On a certain level she enjoyed the exercise. It gave her a rare opportunity to simply construct a looped program and execute it over and over. It allowed her to operate, and more importantly, feel like a machine.

In a world that expected all of its robotic citizens to mimic humanity, Beth reveled in a moment of raw robotic sensations. Regardless of how much she looked and acted like a human, she wasn’t, and she liked how that tickled some of her programmed responses.

Eventually everyone who was invited, was here. SHe darted up the stairs for a moment and let the receptionist know as much. With a curt nod she walked around her little desk and locked the front door. If anyone needed out, that was easy to accomplish, but for now, the spa was closed to the outside world.

By the time Beth reached the base of the stairwell again, the sounds of sex were already beginning to slither up to her audio sensors. That drew a smile. She might as well join in. Her tank top came off in a single, well programmed move and revealed the nicely proportioned breasts attached to her chest. Shoes kicked off and jeans removed. There was a brief moment where she contemplated just letting her clothes fall where they were, she was the host after all. But in the end they were stuffed in a bag and she lightly stepped down into the pillow studden pit at the center of the space.

Evie and Kyla’s trip to the table displaying a wide spread of alternate sexual modules was a productive one. Evie wanted to try each and everyone, but Kyla reminded her that there would likely not be enough time to try out each one, though there was plenty of time for one, or two, or five…

Kyla, meanwhile, plucked one of the male sexual modules from the table. Longer than average, which was no surprise, but it wasn’t one of the monstrously large ones. Though there were other androids at the table who were eyeballing it. She wondered for a moment if they might cross paths over the course of the day. That didn’t matter at the moment though, she and Evie were picking something nice out for one another and then stepping into the technicians room to have them swapped out by a professional.

“Good morning, here for a little tune up or do you- Oh, yep, hardware to install.” The chipper technician said to Evie and Kyla as they entered the small IT space. “Well the first thing is for you both to authorize me as an occasional administrator on your systems, just a one day pass.”

She tapped a small badge on her shirt and once Kyla and Evie were both looking at it she lifted a small plastic cover on it to reveal a QR code. The pair of female robots could have stopped their optics from scanning it, but there was no need and they knew it.

The scan triggered a pop up to appear in each of their fields of vision. A system message asking them to grant the entity with the attached digital signature to a 24 hour all rights admin pass. Both confirmed, and once done their own system replied with a data packet of their own, confirming the permissions.

Once received, the technician dropped all of the sweetness and gentle bedside manner she had before. Her voice was smooth and flat as she ordered rather than asked Evie and Kyla to get up onto the work benches she had set up.

Without hesitation, without even changing their facial expression didn’t even change. For all the sentience and sapience that the pair, and indeed all the robots in the spa that day had, it was a program that could be locked and suspended.

“Spread your legs.”

The simple command took precedence over absolutely everything else. Cute little responses were formulated, but never spoken, little fidgets and jitters were sent to the processors, but were rejected. All because the administrator told them to do something, everything else could wait. So both girls pulled their heels back, lifting their knees and let the motor controls in their hips and knees relax, allowing gravity to gently spread their legs open and expose the feminine sexual units there.

“Disengage locks and eject.”

Another simple command. So easy to follow. The muffled ping of mechanical latches releasing didn’t even register to the girls, they weren’t listening. Why would they? Even when a pair of gloved fingers dug into their slit, curled until there was some friction and then pulled out the entire sexual module, there was still no response. None was needed. In that moment, while their artificial minds might be lustfully enjoying the moment, there was nothing in their operating system that would express that, because they hadn’t been ordered to.

Both modules were plucked from their host bodies. The soft fleshy end giving way to the cold metal and plastic mechanisms behind it. A long tube-like structure attached just behind the supple flesh, perfect for taking in a long thick cock.

Evie’s was far more sophisticated, or at least sleek. Dull grey plastic plates covered the myriad of tubes and wires that ran along the robotic sex. Kyla’s, on the other hand, looked like it had been dismantled and reassembled over and over. Because it had been. The amount of modifications the robotic redhead had done to herself to eek out just a little more pleasure was truly an incredible accomplishment.

Regardless of how often it generated a trip to her local mechanic. The two were on a first name basis now and she was often greeted with ‘the usual?’ She was going to pay for that woman’s luxury upgrades.

Even the technician, programmed to be an impeccable professional, seemed a little surprised by it. Still, it was slipped into an anti-static bag, labeled and set aside. With that done, all that remained was to install the new module. Beth’s preparations paid off as all of the modules had a small amount of storage space on them, and drivers for each and every model in attendance had been preloaded. All that needed to be done was to slide it in place and let the automated installation take place.

Evie went as far as to let out a small gasp as her chosen module was clicked into place. She was an elegant machine, and it smoothly nestled into place. The lock was little more than a distant ping as the mechanisms clicked home. Then the installation started causing her operating system to dutifully take in the drivers and install them.

While Evie installed Kyla had her sexual module inserted. The technician smirked at it, fitting the thing into place and jiggling it a little to get it to slide along the rails inside of Kyla’s hips. Modified bots were always an..interesting..thing to work on. Still, it finally clamped into place and the data began to flow.

Evie was done, alerting the technician with another small gasp. She stepped around to her and addressed Evie again. “Resume your previous programming set.”

It took Evie’s OS a moment to pull up those configurations, but then she blinked and smiled and relaxed. She was back online and looked from her freshly installed slit to Kyla.

“Self test. One moment.” Kyla replied to a question no one asked.

The mismatched sex between her legs stiffened, twitching slightly as it rose from between her otherwise shapely feminine legs. Once it was up, there was a moment where Kyla sucked in a deep breath as if she were preparing for something strenuous, though the technician knew it was just a quick blast of cooling for the girl's processor core. Then the cock seemed to harden in a way that Evie found both hard to describe while being unimaginably enticing.

“Complete.”

Simple as that, and the administrator lock on her system ended. Kyla’s OS pulled up the previous configuration, even without the explicit request to do so, and then she blinked. Once her human emulation was back online her newly installed cock sagged and deflated, coming to rest against her thigh. Evie pouted at that, and it didn’t go unnoticed.

“Thanks doc!” Kyla said, tossing a salute her way.

With that, the girls swept out of the office and out into the ever growing chorus of pleasured groans and lewd sounding moans. Cynthia strode to the doorway and leaned against it, crossing her legs at the ankles and just watching, letting her optics record some of the juicier bits as she waited for the next robot to saunter in.

Beth had made her way to one of the tables and stashed her clothes before turning back to the scene before her. She had long since finished the last of her mechanically spoken welcome message. Once her darker shade of skin joined the overall nudity of her orgy, she turned and surveyed the scene. Her optics bouncing from place to place, swiveling silently in her robotic sockets and her artificial mind taking it all in.

And there was a lot to take in.

A few dozen or so guests had arrived, sporting a two to one ratio of female machines to the male android population. There was a decent amount of purely male on female sex happening, though there were more than a few cases of those pairings being joined by others. There was little complaint from any of her guests. She had, after all, invited those she knew that would be welcoming to this.

In the pit in the center of the room there were a myriad of parts, remotely connected to their owners, most of the time, and adding to the writhing mass of flesh and metal. Beth sucked in a deep breath, not because she needed it at the moment, her own cooling systems were purring along easily, but because when she let it seep out of her nostrils she knew it would be the last one she took for a little while.

She let her smile fade as her operating system obeyed the commands of her own artificial intellect. Shutting down many of those small things that would make her look and act human. Small little fidgets, the gentle sway of her hips as she moved her weight from one foot to the other. Breathing. Blinking. As she descended into the pit as a machine who knew it was a machine and delighted in that fact.

It slipped down to its knees, leaning in to let its lips press into the top of a foot, toes curling as the owner gulped down an almost comically long shaft into her throat. The sensations were overwhelming to the operating system, but there was more than enough remaining processing power to splay out the toes, curling them with every thrust and relaxing them a moment later.

The dark skinned robot continued to move, continued to kiss. A trail of faint saline based saliva from its tongue trailing upwards. Across the thighs, triggering the woman to spread her legs and invite the robot into her waiting slit. Slick folds, ready and waiting invited her in, and Beth was not going to deny herself or programming from that.

The vague change in pitch as the android gurgled on something stuffed in her throat and now Beth’s tongue inside of her clit was barely imperceptible. Still, the pleasure was rising and it would only be a matter of time before there was some kind of explosive reaction from that. Computers all worked, relatively, the same way. Do something to trigger a program to load, the computer loads it, and then it’s executed. Simple as that. Beth was doing her part to mechanically and efficiently trigger those events.

It wasn’t long before Beth felt a new sensation slap across her rear end. A well swung hand produced a sharp sound and Beth’s purely artificial mind had to decide. Look and see who that was, or just keep eating out the robotic woman in front of her.

Surprises were the spice of life.

Her tongue remained firmly planted between the flexing folds of the woman she was with. Her toes flexing harder now with every passing moment. Beth was fine with that, she was a machine, and she was doing what she was programmed for. The data scrolled through her circuitry like a merry band and it made her move and moan and lick on.

It also made her chest drop a little more and present her rear end to whoever was behind her.

Soon the dark skinned robot found herself filled from behind. The thick shaft attached to one of her guests found no resistance as it drove deep inside of her own moistened slit. Hands were on the hips and pulling the android host hard against the body. Beth’s sensors only barely registered that those hands and hips felt far more feminine than masculine. That deserved a look.

The timing couldn’t have been more perfect. Beth pulled back and looked over her shoulder as the woman she had been working on executed those loaded programming sets. She wailed in raw sensual ecstasy, and not for the first time today, nor the last. But as she moaned around the cock in her mouth she pulled away from Beth, choosing instead to rise to her knees and suckle more on her user.

Beth made no reaction to recognizing Kyla. Her human emotional responses were offline by choice. Right now was a time for Beth to feel like a piece of equipment rather than a robot girl impersonating humanity. Though the short crop of bright red hair and pale green eyes resting among a field of freckles was more than enough to confirm who it was. The already stiff cock was new, but welcome. Beth nodded once to Kyla, consenting to whatever was about to happen and then turned back.

The moment of distraction allowed for an open spot in front of her, and Beth found herself confronted with someone familiar. Evie’s form slipped into view and Beth’s optics took her in. Raw data collection started. The facial features and tell tale blue streak in her hair registered perfectly in Beth’s database of known entities. The playful smile and the half lidded eyes were only confirmation of that. Though, the pussy between Evie’s legs was unfamiliar. Freshly installed and obviously not her default because the skin tones were off just enough.

Not that it would stop her robotically lustful programming. Pleasure was pleasure, it was another thing to trigger, and Beth knew what she was doing. She leaned in, and immediately dug her thumbs deep into the soft skin around the artificial sex.

Software latches were fine for maintenance and parts swapping, but there was something so raw, so visceral, about one machine manually disengaging the locks on another machine that sent shivers up the spine. Evie in particular let her head roll back as her friend and host unlatched the bindings holding her newly installed sex in place.

Beth was gentle and cautious to slide it out of her friend, allowing a moment or two for the remote session to engage and link up with Evie’s operating system. The shiver that rolled down Evie’s body let her know the connection was made, and then it was time to bring the detached pussy to her mouth.

Now it was Evie’s turn to add her voice to the din of moans in the room. There was something so hedonistically pleasurable about having her most intimate parts removed and used. She would never grow bored of it, and she would never have to.

The rhythmic thrusting from behind her made for a few awkward movements, but that was all part of the fun. Beth’s highly calibrated systems adjusted to it. Leaning back when she expected a thrust and wiggling a little when Kyla was pulling back. Her breasts swayed and fell into a similar rhythm, as did Evie. All three writhed and moaned and found their operating systems flooded with sexual data that only contributed to the rising need for release.

Each of the mechanical women felt it, to some degree or another. There was no timer, no percentage building from zero to one hundred, just new processes that were spooled into existence and sent to the operating system. They were parsed and processed and tagged and logged. Each one of them was a building block in an ever growing sequence that would eventually crest into an outward expression.

Each thrust from Kyla’s cock into Beth’s wet folds contributed to the redheads orgasm sequence. It helped decide how it would execute. It would add flavor and depth to it. It would determine how hard she would be panting once she released. It would tip the scales on where and how hard Kyla let her love fly.

Beth, operating purely as a machine of pleasure at the moment would take in those thrusts and analyze them. They informed her operating system on how vigorous she should be fluttering her tongue against Evie’s artificial clit. They let her know how to adjust the volume on her vocal module to let out just the right keening squeal once that orgasm did arrive. Evie’s hips thrusting into her mouth and jockeying for more of the brown skinned beauties tongue would play a part in if Beth even executed that orgasm at all, or if she remained purely mechanical and coldly thanked her users.

Evie’s eyes fluttered with raw pleasure and her operating system gathered the electric joy she felt from the luxury model sex unit that was previously between her legs. The small amount of lag between when Beth would slowly drag her tongue up the entire length of her slit and when her processors registered the data didn’t matter. It came in bursts of packaged data and that data was unpacked and processed in equal bursts. Her own climax was steadily climbing, the building blocks that Beth was laying out were stacking up, and once they reached their height Evie would let the sexual module and its associated programming do what it was made for.

That was until a new figure loomed over Evie, blocking out the dim lights above the pillow packed sex pit. A body lowered over her, and she made no move to try and stop it. Natalie’s equally slick folds found their way to the small part of four robotic girls and joined in. Her moans coming out as louder, perhaps than they should have been. Partially because of just how excited she was to be there, but more practically because of the lack of buffering between the speakers in her throat and the world around her.

Natalie’s head was missing from the top of her neck. Missing was probably the wrong word, she knew where it was, even if Evie didn’t It was in Kyla’s hands, brought to the redheads lips for a long distance kiss. Filled with equal parts passion and lust. Still, she squatted over Evie and accepted the robot's expertly crafted tongue into her. It took more than a little processing power to truncate the enormous amount of requests to bounce up and down. She knew that she always did that and was trying to leave space for Evie to work.

And work she did. Natlaie might have tried to stay still, but there was a quivering in her servo motors that was beyond manual control. The flow of data and electricity was too great for them to stay still just like it was impossible for Natalie to control the volume of her lewd sounding grunts and mewls. Not that it mattered. They were another voice in the rising chorus around the four.

Each of the four robotic women knew how long they were engaged with one another. There were internal clocks that would track that. Log files would read out, down to the second how long it took from first contact to their glorious group orgasm. It wasn’t agreed on ahead of time, but there were certain things that a synthetic woman’s operating system just picked up on. Subtle signs, data points and pattern recognition. It was what A.I.’s like them were good at.

That change in pitch. The hungry squeals. The audibly spoken phrases. Those helped too.

Everyone. Every single android, fembot, gynoid, and robot in attendance needed to be recharged for some amount of time during the day. There were just some activities that took a lot of juice out of a power cell. Beth had accounted for that, and there were more than enough power cables of every different type to accommodate.

Soon though, it was time to be done. Wrapping up and redressing, everyone made their way to the stairs for an exit on shaky legs. Motor control systems were fragile things, but Cynthia was happy to check out anyone who mentioned that they might be a little weak in the knees still. She had to remove a lot of previously installed sexual modules and modifications anyway, it wasn’t too much extra work to run a quick diagnostic.

Evie, Kyla and Natalie had offered to stick around to help clean up. Cheerfully commenting that they helped make some of these messes, so they might as well.

Beth had long ago re-engaged her human emulation. She loved the dip into being purely mechanical, but for interacting with her friends and being social, her human emulation was needed.

The consequence of that, she knew, was going to be the flood of sensations and executables that had been on standby while she mechanically fucked her way through her friend group. She was fully sentient, and because of that fully in control of when and where those executed. Like slowly opening a bottle of soda that had been shaken, she could let out just a little bit of that bubbling pressure.

For the hour or so it took to tidy up, she did just that. Letting her mind slip into autopilot a bit, while her higher level A.I. indulged itself. Feeding on a steady stream of low level pleasure. It would be a high she could ride for a long time. Well into the night and perhaps the next day.

She sighed, not because of the pleasure, but because she felt a small glimmer of pride and joy. She loved being a robot.
