Building Umeko

Hisoka had finished her. He had poured his heart and soul into the build. Not to mention most of his savings. She sat there as still as a statue. Pretty as a painting, her sexy curves clad in technology and hyper realistic artificial skin. Hisoka had hit the wall. That's when he remembered Anzu from school.

Anzu had sat in front of him in advanced math back in college. Anzu had gotten a great job offer working as an AI programmer. She was literally a genius. Quirky. Always a loner like he was, big droopy boobs and a stocky build. Not unattractive if she'd put a little effort into it. Straight brown hair and eyes. Plump lips on a round face that just begged to be fucked.

The kind of girl you'd bring home at closing time. Except she was too intelligent. Most guys felt intimidated withing the first minute or two of talking to her. She's gotten a lot of rushed apologies.

"Anzu. It's me Hisoka from school. I need your help." He'd said on the phone.

"Hisoka, huh? I think I remember a Hisoka from math. Is that you?" Anzu asked.

"Yeah. That's me. I built this robot, and now I'm kinda stuck on the control part. I mean everything works great, it's just really clunky. I remembered that you were really good with stuff like that. Maybe you could take a look at the programming. I could pay you." Hisoka begged.

"What are you doing Saturday?" Anzu asked.

"Nothing. You wanna have a look at her?" Hisoka asked hopefully.

"I guess. Text me your address." She said giving Hisoka her cell number. "I'll see you around 8. Have breakfast ready."

Anzu looked the same as always. Blue jeans, converse hi-tops, flannel shirt, her big tits sloshing around unbound like aimless puppies looking to escape the pen.

"You look great! So good to see you again!" Hisoka flattered.

"Yeah. Whatever. Where is this robot of yours?" Anzu said, taking the tea and rice cakes from Hisoka's hands.

"She's over here. C'mon." Hisoka led Anzu back into his workshop.

Anzu did a quick survey.

"Nice job... mechanically. You built yourself a little hottie, huh?" She said sarcastically.

"Companion. You know me. I've always been awkward when it comes to girls. Ha-ha." Hisoka admitted.

"Never really noticed." Anzu said. "Can you power it up for me?" Anzu asked.

"Uh, Sure." Hisoka said, flipping a reset switch on the back of her neck concealed by her long black hair.

"Hello, my name is Anzu" Anzu said when it had finished booting up.

"I am Umeko." The robot answered in a flat monotone, extending her hand woodenly for a handshake. "I am pleased to meet you, Anzu."

"Okay, I can see your problem." Anzu said turning to Hisoka. "What's her operating system based on?"

"Sentient AI 3.8.1 Latest patch." Hisoka answered.

"Well, you did an okay job with the implementation. But as a stand-alone, that system has very serious limitations. At least two generations behind the development curve for stuff we're working on right now. Motion control is flat linear. Speech generation is pretty generic monotone. We can do better. There are some third party open source patches, that we can turbocharge." Anzu said.

"So, you'll help me?" Hisoka said hopefully.

"Yeah. Looks like fun. Plug her in to the terminal and I'll get started. We'll see what I can do in a few weeks. Do a better breakfast next week." Hisoka said.

"Great! Thank you so much." Hisoka laughed. "I'm so grateful."

"No problem. Just don't bug me too much, okay? This isn't going to happen overnight." Anzu said pointing Hisoka out the workshop door.

For the next two months or so. Anzu would show up on Saturday morning, eat him out of house and home, and work on Umeko's systems. Sometimes she'd take the AI core, or the personality module back home with her.

The improvements were steady and at times dramatic. Umeko's movements were attaining a level of fluidity that approached nothing short of gracefulness. Her voice now had a sweet lilting quality that Hisoka found extremely endearing. But most importantly she was learning at an accelerated pace.

"How was your day, Hisoka?" Umeko greeted him at the door.

"It was okay. It's good to be home, though." Hisoka said, taking off his shoes.

"Dinner will be ready in about twenty minutes." Umeko smiled. Leaning in and kissing Hisoka sweetly on the cheek. "It's nice to have you home. What shall we do tonight?"

"I don't know. Maybe watch some Anime? There's a funny new one that's just come out." Hisoka said.

"Anzu is coming over again tomorrow." Umeko said. "I'm looking forward to seeing her again. She makes me laugh."

After dinner they sat on the couch watching the TV. Umeko held Hisoka's hand, her head resting lightly on his shoulder. Hisoka was happier than he could recall ever being. When the show was over, they went to bed.

Anzu had programmed her to "sleep" and Hisoka looked forward to feeling her in bed with him. Even though she wasn't "real", he would cuddle against her and she would make periodic adjustments to her position, as if she was shifting in her sleep. Hisoka loved it.

Anzu arrived and had breakfast as usual. Taking Umeko's hand, she led her back to the workshop. A short while later Hisoka began to hear noises. Anzu mostly. Muffled and mostly non-verbal. Hisoka began to become concerned about what was going on back there, so he let himself into the room.

Anzu was up on the workbench her jeans were on the floor and her big tits swayed lewdly against the flannel of her open shirt. Umeko was between her legs, face buried in the huge thatch of pubic hair that ran from just below Anzu's navel halfway down her thighs. Anzu shot a warning glance at Hisoka just before she started to cum.

Hisoka wasn't sure how to react. Anzu was encouraging Umeko to keep going, and Umeko was enthusiastically complying. Hisoka knew that Umeko possessed the physical capacity for sexual behavior, but this was the first time he'd really seen it manifested. And something about the way Anzu's self-assurance, and unabashed sexuality was oddly arousing. She might not be a beauty queen, but she did have Hisoka's cock stiffening in his pants.

Hisoka retreated from the room in confusion. It was another hour and a half before Anzu strode into the living room still in just her shirt.

"Enjoy the show, you pervert?" Anzu spat.

"You're... fucking my robot! Shit..." Hisoka stuttered.

"Yeah, and she's a total biscuit too. Better than any real girl I've ever been with." Anzu chuckled.

Hisoka just stared at Anzu and shook his head. "You turned out to be a real piece of work, you know that?" He finally retorted.

"Hey, look. Don't be mad. You built her. Are you telling me you haven't tried something with her yet?" Anzu said.

"No! I haven't." Hisoka said.

"Well, you gave her all that shit, you should know..." Anzu pointed out.

"I don't know. I haven't thought about that." Hisoka said.

"Bullshit, Hisoka. If you hadn't thought about that you wouldn't have built her for it." Anzu stated. "And I could see the lump in your pants. I see it now. I bet you wanna take it out so bad."

"Anzu!" Hisoka gasped. She was right though. He was staring at Anzu's tits swaying in front of him. So close. He couldn't even look away.

"You wanna touch 'em, don't you." It was a statement not a question. "C'mon, go ahead. I won't stop you!"

Hisoka reached out and took Anzu's melons in his hands. They were soft, and he squeezed them slightly, evoking a soft moan from Anzu. He gave her nipples a rub and she moaned even louder. He saw her hand go to her crotch as he raised one of her nipples to his mouth and sucked on it. It tasted nice. Soap and sweat... and Umeko? He felt her hand on the back of his head, encouraging him to explore further.

She turned and sat on the couch, pulling Hisoka down next to her and kissing him hard. Hisoka kissed her back clumsily at first. He had always been too shy around girls. It was one of the reasons he'd built Umeko. He wasn't sure about what he was doing. He wasn't sure about anything.

Anzu was rubbing the bulge in Hisoka's pants as they kissed and he played with her tits. He felt her hand unbutton his trousers and slide down to encircle his cock, which was rock hard.

"Nice." Anzu said, breaking their kiss and pushing his pants and boxers to the floor.

Hisoka saw Anzu lean in, her plump lips around his head as she began to suck him for all she was worth. Hisoka felt like he was on a rollercoaster. Butterflies as she stroked and sucked him like a wild woman.

He knew the mechanics, but wow, the reality was epic. He knew what she was trying to do. There was little he wanted to do to keep her from getting her way. She was stroking him harder and harder, taking as much of his shaft into her mouth until she'd gag a little every few strokes. He was going to cum and she knew it. Knew it and was ready.

He shot in her mouth. By far the most intense orgasm of his life. She looked up at him catching his gaze as his shaft pulsed filling her mouth with his spunk. He really wasn't ready for what came next. She sat up next to him and kissing him, pushed his load with her tongue, back into his mouth, kissing him until he had swallowed it all.

"That's it, Hisoka." She ordered. He swallowed. "Good boy. Practice with Umeko enough, and maybe next time I'll let you fuck me."

Anzu pulled on her pants, buttoned up her flannel shirt, and strode out the door. Hisoka, his mind blown by what had just happened, stared at the blank TV screen for the next twenty minutes.

A short while later, Umeko emerged from the workroom. Going into the kitchen she returned with a beer, which she opened and handed to Hisoka who was still sitting bare assed on the couch. He took a swig, wiping his mouth with the back of his hand.

"Anzu said you might be upset by what you saw." Umeko said. "Are you?"

"I think dazed is more like it. Maybe a little upset at first." Hisoka said. "I don't really know."

"Anzu is teaching me about my sexuality. She said that eventually, you'd want to explore that with me. She's quite fond of you, you know." Umeko said.

"I... well I don't really know what to say. It's hard to tell with her. I've always been awkward around women. The sex part really never came up before." Hisoka admitted.

"I know. Anzu told me about that too. Shyness, she called it. Anzu said she used to be like that too. You needn't be that way with me, though." Umeko said.

"I... well, it's how I've been for so long. It's hard to act any other way." Hisoka admitted.

"I can't say that I understand. As an AI, I can adapt to things. Especially with the upgrades that Anzu has made. I would expect you have some capacity to reprogram your own behaviors. Anzu did make a request." Umeko revealed.

"What's that?" Hisoka asked.

"She wants me to sleep with you, without my cover plates on. Sex ready." Umeko said. "That is, if you're okay with it."

"Um... I guess?" Hisoka said.

Hisoka remembered how happy he'd been when Umeko's breasts had arrived. Remembered installing them in her lifeless metal and composite frame. The same with her ass and pussy. It was different with her just laying there on the work bench or hanging from her stand powered down. Like building some kind of fancy model. He'd gone way overbudget on those items. He was glad now, looking at her, that he'd spared no expense.

He could feel them, perfect D-cups pressing soft and warm, against his back as she spooned him on the mattress.

"You're not sleeping, Hisoka. Am I doing something to upset you?" Umeko whispered.

"No. It's okay. I just need to relax." Hisoka replied. "Clear my mind."

"Can we kiss then?" Umeko suggested.

"Okay..." Hisoka rolled over, remembering Anzu's mouth on his.

Umeko took his face in her hands and brought her lips to his. Softly lingering Her eyes gently closed. It was different from Anzu's hunger. It hung in the air like a pleasant fragrance. Umeko felt so alive to Hisoka.

Umeko broke the kiss and opened her eyes. She smiled sweetly at Hisoka, and brought his hand to her breast. Unlike Anzu's wobbly funbags, Umeko's were far firmer. Sighing, she leaned in and resumed their kiss, this time with a slightly elevated passion.

"That feels good, Hisoka" Umeko moaned into his ear in between kisses. "You are making me happy."

Hisoka could feel his boxers starting to tent. If Umeko was aware, she didn't let on. They continued to make out. Hisoka felt the energy of his arousal coursing through his whole body. Umeko's hands explored him like she was mapping his body out, her hand coming to rest at last on his erection.

"Would you like to put this inside me, Hisoka?" Umeko asked sweetly as she eased onto her back, her legs parting suggestively. She gently pulled him over onto her, her hand wrapped around his erection, her other hand pushing his boxers down.

Hisoka felt the head of his cock enter her love hole. She was warm and wet and let out a low moan as he pushed his shaft deeper inside her. All the options. This justified every cent.

"That's it, Hisoka, make love to me, darling." Umeko begged. She was so beautiful. Her pussy was doing things to his cock. It felt nothing like masturbation, her body moving with his, just out pacing his desire to make it last. In maybe three minutes time, he blew his load inside her. They lay in each other's arms for a while, until his softened cock, a tired little worm, slipped free of her flooded pussy.

In the morning, they did it again. This time, Hisoka knew more what to expect, and he was starting to get Umeko figured out. He could think of little else all day at work. Again, before dinner, and he made her cum all over his cock. Again, when they went to bed. He slipped into her pussy from behind this time. She just felt so fucking good.

Hisoka was hitting his stride. He had learned how to make Umeko cum with his mouth as well as his cock. She had sucked him off a couple times. The TV hadn't been on in days. And tomorrow was Saturday, which meant Anzu would be dropping by.

Hisoka didn't quite know what to expect. Or rather he did. Anzu had texted him a few times on Friday, telling him how horny she was, and that she knew he'd been fucking the daylights out of Umeko all week. She was probably getting systems reports on Umeko.

It didn't take long after breakfast was finished. Anzu slumped on the couch with her tits out twisting her own rubbery nipples like taffy while Umeko ate her pussy through five or six orgasms. Hisoka was vaguely uncomfortable by the whole scene, but Anzu's body shaking as she came again, and Umeko's wet noises, her face buried in the rainforest of Anzu's pubes, was somehow ferally erotic.

Hisoka had a vague notion of what act two was going to entail, and he couldn't help himself seeing Umeko's sexy ass in between Anzu's sturdy thighs. He had his cock out and it was hard as he slowly stroked it. Anzu had gotten up off the couch and fairly dragged Hisoka to the bed.

On all fours she urged Hisoka to mount her. Hisoka buried his cock in her to the hilt in one go. She shuddered and came. Her tits sagging like hound's ears, nipples dragging along the mattress top with each thrust, swinging back and forth, making her cum even harder. Hisoka had her by the hips, transfixed at how it was at the same time dirty, and incredibly erotic.

Anzu was a mess. Her pussy splooshing and gushing her cum which ran down her inner thighs in rivulets. Hisoka's hips making wet smacking sounds as he bottomed out against her ass. She was a force of nature, athletic and percussive, a real contrast compared to Umeko's graceful loving.

Hisoka was reaching the point of no return. Anzu came again and Hisoka pulled out shooting all over Anzu's ass.

"What'd you do that for?" Anzu asked.

"I didn't know what..." Hisoka started.

"Next time don't do that." She scolded. "You bust in my puss. Got it?"

"Hey. I just thought things were risky enough... are you on birth control?" Hisoka asked.

"That's my business. Yours is to get me off. Got it?" She reiterated.

Anzu stayed overnight and didn't leave until late Sunday afternoon. The entire weekend was consumed by an ongoing tag-team threesome. By the time she left Hisoka's dick was sore and his balls were drained.

Even Umeko seemed a little worn out. They made love that night. Nice, sane, gentle love. Umeko, at rest in Hisoka's arms, felt good.

"Look, I know I was a bit much last weekend." Anzu said. "I was just so fucking horny all week thinking about you two going at it. And it's been ages since I was getting anything on even a semi regular basis. I got a little carried away."

"It's okay. I found it a bit overwhelming at first, but it was also a lot of fun." Hisoka said. "After all you did for me... I mean I could never have gotten Umeko working nearly as well, not even if I got lucky."

Anzu blushed. "I should be thanking you. I know I'm not a beauty. I have a strange body. I don't date, because I don't get asked. Mostly I'm okay with that. Sometimes it gets to me, though."

"Hey. A couple of weeks ago, I was a 24-year-old virgin. You fixed that. I'm not exactly a porn star, but there was something really hot about fucking you. It wasn't exactly about looks." Hisoka admitted.

"So if I wanted to do it again?" Anzu looked at Hisoka hopefully.

Forty minutes later, Hisoka was busting a nut in Anzu's sloppy pussy. Anzu face down moaning and crying into the pillows. A month ago, Hisoka had never had a girlfriend. Now it looked like he had two.

And it turned out Anzu had a softer side as well. It came out most often when she was with Umeko one on one. Umeko had blossomed far beyond the programming Anzu had done. Her AI adapting and changing with the reactions of her lovers.

Anzu had a surprise. The house. It was set back from the road. A small farm, the main house had only been recently built. An older barn out back, mostly a workshop now. The inside was simple and spacious. Anzu had spared no expense hiring the most talented decorators. There was a big, custom made bed in the master bedroom with a huge ensuite bath.

All the money she'd been making. She never could figure out what to do with it. Now she had.

Three other bedrooms, one set up as an office, one as guest accommodations, but it was the third one, the one next to the master suite that caught Hisoka's eye. Walls, painted in bright colors. There was a crib situated against the wall facing the window overlooking the fields.

Hisoka, slack jawed, just looked at Anzu, who nodded curtly.

"I've sent for Umeko's things and yours, Hisoka. We'll put the rest in storage. I've settle things with your landlord. You'll both be coming to live with me. I'm not raising this baby alone." She grinned, her hand on her tummy.
