“Good morning, Z.”
“Good morning, sir. How are you?”
“I’m just fine. What’s the weather like today?”
“It’s going to be mostly sunny with some clouds towards the afternoon. It could rain tonight. Might I suggest to bring in the hay before then?”
Anne was quite fed up with the inane conversation that was happening on stage. It seemed the next model was mostly more useless social interaction upgrades. It was the kind of pointless small talk she’d rather not have with another human, let alone a machine. And she certainly didn’t want advice on how to run a farm from it. Her own Zed unit had all but the most necessary voice responses turned off. She didn’t need a “Yes, ma’am.” every time she told it to do something.
“Do you fancy a game of chess later?”
“Absolutely, sir. I shall do my best not to beat you quite as quickly as I did last time.”
The audience laughed politely.
Zed was necessary for her business. The farm was mostly automated but there were lots of small jobs that didn’t make sense to get specific machinery for. Jobs that were too heavy or monotonous for her to do herself. A strong robot with the ability to work autonomously was absolutely vital to make it work.
The sales rep unconvincingly fell off the stage.
“Help, I’ve broken both my arms and I can’t get up.”
“Stay calm, sir. I have called an ambulance.”
Of course, Anne’s unit already had this ability. It was part of the reason she got one. If something happened it was good to have a 200 kg robot come running to your aid. She did feel safer with Zed around. And, to some extent, that made her feel less lonely. But to have conversations or play games with it? That was just weird. If it wasn’t for its human-like appearance and ability to work of voice commands no one would have considered it.
“As you have seen, the next Z-106 model is not only a competent worker but also… a friend.”
“Or a lover.” the conferencier added.
The audience laughed loudly. The third party modification that the conferencier without doubt was referring to must be a great embarrassment for the company. At the same time it probably increased their sales. The sales rep tried his best to ignore the comment.
Anne wasn’t surprised this type of modification had come about. The Z units were designed in a very masculine way. They were strong, obedient and often used by people who worked alone. Like herself. It didn’t bother her nearly as much as the social aspects did. This didn’t make it anymore human. It was just another job that it would be capable of.
What had surprised her was the quality of the product. It wasn’t just a stick glued on. It was a pretty advanced piece of hardware backed by some well written software. At least that’s what she had read about it. It was also expensive. But the last year had been good. She wanted it. And it was in budget.
Anne visited the rest of the fair before she went to the booth that sold the item. She didn’t want to carry it around all day. The peddlers were packing up for the day. A lone person handled her transaction.
“Try this easter egg.” the man said in a hushed voice after checking that no one else was listening.
He dropped a small piece of paper in the bag with the boxed item. Anne didn’t feel like inquiring further. She nodded and was soon on her way home.
When she returned home she checked that everything was running smoothly. She found Zed in the barn sweeping.
“Anything to report?”
“No, ma’am.”
“Get cleaned, then come to the workshop.”
The machine put away the broom and walked towards the garage. Anne went into the brightly lit workshop. The walls were lined with tools and work surfaces. In the middle was a big stainless steel table firmly bolted to the floor. Everything was spotless. She didn’t like messy work places.
Anne sat down by the table and took out the box that she had bought. She opened it and looked over the instructions. There were some assembly required. Plus a software upgrade. But nothing that looked particularly complicated.
She got up and grabbed the required tools just as Zed entered the building. She found the USB stick with the upgrade in the package and plugged it into the robot.
“Performing software upgrade.” Zed said after a moment.
Anne went back to the chair and lowered it.
“Come here.”
She unscrewed the groin plate. Behind it she found the main bus which she would have to add a new interface port to. This required some serious tampering. Obviously, nothing was supposed to attach this way. But the instructions were easy to follow, along with plenty of “WARRANTY VOID” warnings.
“Software upgrade complete.” Zed stated.
Anne removed the USB. She grabbed the new groin plate from the box and connected it to the interface port. Then she screwed it onto the chassi. A smooth plate was provided that would attach to the new groin plate when one didn’t wish to have the unit ready for action. So to speak. In this configuration the Z unit looked pretty much indistinguishable from an unmodified unit. Which was good in case she ever got company.
The other attachment was the fun part though. She picked it up from the box and attached it to the plate. It started out in its soft state. She let it run through her hand. It was made of a silicone substance but felt rougher than she had imagined. A bit like the rubbery surface of a truck bedliner. In that way it matched the units industrial appearance.
It was time to perform some tests. If the software update had been installed correctly and she had connected it properly Zed should be able to control all its functions now.
“Get hard.” she started.
The member grew slightly and raised to a slight upwards angle from the base. Even in its soft state it was pretty big. Now it was a decent size. It didn’t have the same range as a human male. This was more of a ‘shower’ than a ‘grower’. She let her hand run up and down its shaft. It was firmer than before but felt like it had more to give.
“Harder.” she requested.
The member grew a bit more both in length and girth. It also raised further upwards. Again she stroked it up and down. Now that it was a lot firmer it also felt smoother to the touch. She tried to bend it downwards and it gave way pretty easily.
“Go to the hardest setting.”
Now it became rock hard and pointed almost vertically. It was almost impossible to bend without excessive force.
“This setting is not recommended.” Zed stated.
“No, I can see why.” Anne mumbled to herself. “Go softer.”
Zed shrunk the appendage a bit. Obviously all the characteristics were linked. Want it small? Then you also get it soft and rough. Want a big one? Then it gets hard and smooth. It made sense.
“Vibrate.”
The shaft started to shiver in her hand.
“Faster. Actually, go to the fastest setting.”
The vibration reverberated down her arm as she held on to the quivering member. She expected Zed to make a statement again but the robot remained silent. Apparently this was a recommended setting.
“Go to the slowest setting instead.”
The member calmed down to an almost complete stop. She could barely feel the vibration.
“A little faster… A bit more… I think that’s the setting I want.”
“Although it is possible to select a specific setting for size and vibration it is recommended that you let me monitor your pleasure levels and adjust these settings accordingly during intercourse.”
Anne dropped her grip and shrugged back from the robot. It took her a moment to compose herself. She hadn’t realized quite how advanced the software update was. It freaked her out a little that Zed not only knew what the new appendage was for but was apparently also well knowledgeable in how to use it.
“Yes, of course. Do that.” she answered after a while.
She gripped on to the shaft again. There was one function left to test.
“Lubricate.” she ordered.
“No lubrication canister installed.”
Drats. She missed that part. Anne detached the appendage and rummaged through the box. There were several bottles provided. Probably because they were quite small in order to fit in the base of the shaft. She installed one and reattached the member.
“Lubricate.”
The whole thing became slippery. It felt like the liquid emerged from several tiny openings located all along the shaft.
“Don’t waste too much of this stuff. I don’t want to have to buy more of it all the time.”
“Understood, ma’am.”
“Go to your default soft state and back up a bit.”
The robot took a few steps back. Its appendage softened and dropped towards the floor.
Anne stood up and kicked away the chair.
Then she removed her clothes.
Her body tingled in anticipation as she stood naked in front of the machine. It responded to her body by becoming hard again. Anne placed her hands on the table behind her and jumped up on it. With her butt on the end of the table she leant back on her elbows and spread her legs.
Zed walked towards her and grabbed her thighs. With its hands as leverage the robot aimed its artificial penis towards her pussy and pushed it in. Anne bent her head backwards and let out a sigh. It had been a while. The robot started fucking her gently. It felt really good. She lay down on the table, found footing on Zed’s hips and relaxed.
After a while she started to become really horny. She didn’t notice it at first but Zed had added a bit of vibration at the end of every stroke. Push in, vibrate, pull out. It left her craving more.
Anne got up on her elbows again. Ready to tell Zed what to do. But the robot pre-empted her. It bent down towards her and grabbed her arms. It guided them to its chest plate. She grabbed on to it. With her feet still on its hips the robot pulled up from the table and quickly grabbed her ass. With her whole weight supported by the machine it increased the size of its cock and fucked her harder.
During one of its strokes Zed pushed in but did not pull out. Instead it vibrated its member deep inside her. This pushed her over the edge. As the orgasm hit she extended her legs and tensed her muscles. Zed held her steady and pulled out. Her legs shook wildly as the orgasm passed its peak.
Anne waited for Zed to continue fucking her. But the machine remained motionless. As she had now lost her foothold she could not indicate that she wanted more with her body.
“More.” she requested.
That did the trick. The machine lowered her onto its cock once more. At first it took it slow, making sure that she could still take it. After it was sure that she could it returned to fucking her hard. Anne enjoyed having her legs free and letting the robot do all the work. She was still feeling the effects of the orgasm in her thighs.
After a while the robot’s programming decided to switch things up. It pulled out and dropped Anne onto the table. It gently pushed her over on her side with her legs at a ninety degree angle from her body and her bottom hanging off the end of the table. Zed’s hand lifted her upper leg and put the shaft against her vagina. It pushed her legs together and started vibrating. The member was riding up against her clitoris. With some movement and size adjustments the robot could control the amount of pressure it put on her clit.
Anne’s whole lower body trembled with pleasure. Her pussy felt empty though. She wanted it back inside but refrained from requesting it. Whomever had programmed this thing knew what they were doing. She decided to trust it. Sure enough, within moments of her thinking it Zed pulled out from between her thighs. Before it returned its silicone cock to her pussy it repositioned her body on the table.
The machine put her on her stomach with her legs pulled up on either side of her. It put one hand on her back and pushed her against the table. With the other hand it pushed against her neck. Anne was completely pinned by the powerful robot as it penetrated her once more. This time it didn’t hold back. It pounded her pussy hard.
Yet again it stopped inside her and vibrated. Anne almost came when it suddenly stopped vibrating and returned to fucking her. The machine repeated this cycle several times. When it once more stopped and vibrated she assumed it would do the same. The orgasm took her by surprise. Zed performed a series of vibrating patterns that prolonged her orgasm. Then it pulled out and released its grip on her.
Anne squirmed on the table. Her body barely obeyed her. Her legs shook violently as she stretched them out. She lay on her back and regained her composure. When she felt calm enough she got down on the floor. Her legs were still a bit unstable. Zed stood at the sink and cleaned its detached appendage.
Anne went through the packaging that she had left on the table earlier. She was thinking of where to store the items when she found the note that the seller had left to her. He had said something about an easter egg.
“Zed, what can you tell me about the easter egg?”
“I am not aware of any easter eggs.”
She looked at the note. It was just a bunch of letters. She read them out to Zed.
“S H P X R Q H C”
Zed reattached the appendage which it had just finished cleaning.
“Turn around.” it ordered.
Anne was about to protest but she was curious. She turned away from the robot and stood against the table. Zed got behind her and used one hand to spread her ass cheeks. The tip off its penis prodded her anus. She wasn’t the type to do anal normally. But today was a special day. She decided that she was okay with it.
The cock didn’t go in yet. It only deposited some lube at her opening. Instead the robot pushed a finger inside. After the finger had loosened her up Zed began the process of penetrating her. A bit of vibration and lubrication helped the sizable member work its way inside. Eventually it was all the way inside her.
The robot put its arm around her. It pushed her breasts upwards and held her firmly by her chest. It enlarged and hardened its member inside her butt. Anne felt some pain as the cock stretched her asshole. She let out a small exclamation of discomfort. Zed responded by increasing the power of its vibrations. This made her anus go numb and it felt good again.
The machine lifted her from the floor. Anne hanged in the air supported only by her asshole and the arm around her chest. She grabbed on to it to get more comfortable. The robot’s other hand reached down to her pussy. When she realized what it was doing she tried to pull it away. But the machine didn’t respond. It spread her pussy open and pushed a finger inside. She felt she’d had enough pussy stimulation for today but she was afraid to tell Zed to stop. What if it didn’t? She didn’t want to find out that she wasn’t in control anymore.
The finger started to stimulate her pussy while the vibrations in her ass grew stronger. Another finger started to work on her clitoris. Anne’s hole body vibrated. Her legs dangled like wet noodles. Her asshole was stretched wide open. Her pussy was getting massaged. She felt like she would piss herself. Then she did. Or was this what squirting was supposed to feel like. In any case it felt good. Her legs trembled as the liquid flowed out of her.
When she had nothing more to give Zed lowered her back onto the table. It removed its hands from her body and put them against her buttocks. With them as leverage it shrunk down its member and gently pulled it out of her. Then the robot detached it and started cleaning it in the sink like nothing happened.
Anne held on to the table while she tried to get her body in order again.
“Zed?”
“Yes, ma’am.”
“No more easter eggs, okay.”
“I am not aware of any easter eggs.”
