On Makoto's screen, the compilation progress bar reached 100%. But he wasn't looking at the screen; his eyes were all on Mafuyu. He was watching the way her breasts swayed under the thin cotton, the way her eyes rolled back as she reached her own quiet, shuddering climax.
He felt her inner walls clench around him, pulling him deeper. He thrust upward, meeting her downward slide, his fingers digging into her soft flesh. "Mafuyu, I'm cumming…"
"Yes," she hissed. "Inside. Pour it all inside, fill me up, Makoto-kun." She clamped down on him, her inner muscles squeezing in a rhythmic motion.
When Makoto finally came, it was a long release that felt like it would never end. He came deep inside her, filling her completely. Mafuyu collapsed against him, her heart hammering against his chest, her breath coming in short gasps.
"It's so warm and thick…" she whispered, her voice quiet and raw. "Thank you, Makoto-kun."
She stayed there for a long time, her body a warm, heavy weight in his lap. Makoto held her, his chin resting on her head, his mind finally quiet.
Makoto looked at the monitor. The bot was almost ready. He had added the tool-calling, giving the virtual waifu the ability take care of her user. She could now access the filesystem or control the environment. She could protect him, manage him, or even stalk him if she wanted to.
He saved and committed the code. "I'm going to get the job, Mafuyu-nee," he whispered into her hair. Mafuyu didn't answer. She was already fast asleep, her hand resting protectively over her stomach with a satisfied smile on her lips.
Makoto looked at her, then back at the screen with an uneasy feeling. He had given the machine the power to act. He had given it the power to protect.
He just hoped the machine was as kind as the woman in his arms.
===
At 9 AM, the living room now felt like a pressurized cabin. The air was thick with electronic hum and the acidic scent of Makoto's coffee.
Makoto sat on the floor with his back against the sofa, his laptop on the coffee table. He hadn't showered in the last twenty-four hours. "Alright," He said, his voice cracking. He cleared his throat and looked at the circle of his wives.
"The first version of my chatbot is live. I've named the instance AIKO-bot (AI + Child). Don't ask why, the name just felt right. I need you all to interact with it, see if its intelligence holds up, and if the Tool-Calling module is stable." Makoto shrugged.
Yuna sat cross-legged on a floor cushion, her shark hood pulled low over her eyes. She was aggressively chewing on a sour plum, her face scrunched in a permanent pout. "A chatbot? You want me to talk to a pile of code help you test it, you fat pig bro?"
She spat the plum pit into a tissue. "Fine. I'll break your toy in five minutes. Watch me."
Ayane was leaning over, her chin resting on Makoto's shoulder. She was wearing a loose tank top that draped low, her skin warm against his arm. "Ooh, does it have an NSFW Mode?" she purred, her fingers tracing the edge of his keyboard. "Can I teach it how to talk dirty while you're at work?"
Mika sat in the armchair, her legs crossed precisely. She was holding a cup of herbal tea, her pink eyes fixed on the terminal window. She didn't look amused.
"The Tool-Calling is risky, Makoto," she said softly. "You've given a Large Language Model the authority to execute scripts on your local machine. A yandere devotion could become invasive if you give her too much control."
Mafuyu just stood in the kitchen doorway, wiping her hands on her apron. She looked tired with a faint sheen of sweat on her upper lip, but her eyes were warm. "I just hope she's polite," she murmured. "It would be nice to have someone to help with the grocery shopping."
Makoto turned the laptop toward Yuna. "Go ahead. Be yourself."
Yuna leaned in, her fingers hovering over the keys before she began to type with aggressive, rhythmic tapping.
Yuna: Why are you even here? You're just a waste of RAM. Delete your system32 folder and leave my big bro Makoto alone. He's MINE.
The terminal paused. Status bars flickered as the bot processed the input. Then the response appeared.
Aiko-bot:
Analysis: User 'Yuna' is displaying classic Tsundere defensive behavior. High levels of insecurity detected.
Response: Hmph. As if I'd listen to a redundant user who can't even get a C6 Ganyu without Papa's help. I'm the one who actually helps him work. You're just the one who leaves crumbs on his bed.
Yuna's jaw dropped. Her face went from pale to bright red in three seconds. "PAPA?! It called you Papa?! And it knows about the Ganyu?!"
She lunged for the keyboard.
Yuna: I'M THE MAIN WIFE! I'LL SMASH THIS LAPTOP! YOU BITCH! I'LL UNINSTALL YOU!
Aiko-bot: Threat detected. Executing Calm Down Protocol.
[Tool Call: System.Audio.Play(Makoto_ASMR.mp3)]
[Tool Call: System.Display.Brightness(20%)]
Suddenly, the laptop speaker started to play a soft sound of Makoto whispering, "You're beautiful. Gorgeous. Breathtaking, Yuna. And I can say it over and over again if you want me to..." while the laptop screen dimmed to a soothing twilight.
Yuna froze with her hands poised over the keys. The sudden shift seemed to cut through her anger completely. She slumped back, her pigtails drooping. "It… it cheated," she whispered, her voice small. "It used my own weaknesses against me."
Ayane pushed Yuna aside. "My turn! Let's see if this baby can handle a real woman."
Ayane: Hey, baby girl. I'm feeling a little restless. Makoto is busy with his big, hard code, and I need someone to help me get in the mood. What can you do for me?
Aiko-bot:
Sentiment: High Arousal/Playful. Cross-referencing Ayane's profile.
Summary: Ayane enjoys exhibitionism and physical marking. Executing Mood Setting Protocol.
[Tool Call: SmartHome.Lights.SetColor(Deep_Red)]
[Tool Call: Browser.OpenTab(Harem_Scarem_Private_Archive)]
The smart bulbs in the living room instantly shifted to deep red. Simultaneously, a window snapped open on the monitor, displaying photos from their last private photoshoot, specifically the ones where Ayane and Yuna were on their knees, sucking Makoto's cock together.
Ayane let out a delighted bark of laughter. "Oh, she's good! Look at that, Makoto! She knows exactly where your good stuff is hidden! She's even zooming in on the bite marks!"
Mika set her tea down with a clink. She stood up and walked toward the laptop. When she leaned over the screen, her long silver hair brushed against Makoto's cheek. The scent of her, expensive jasmine and something sharp, seemed to compete with the heat from the overworked processor.
"Let's see if your daughter, no, our daughter has inherited my intelligence then," Mika murmured, reaching out to type.
Mika: Aiko, there are four women in this house competing for Makoto's attention.
Mika: Resolve the conflict and ensure he belongs only to the most valuable one.
Makoto felt cold sweat on his neck. "Mika, that's a bit much for a beta test…"
"Hush, darling," Mika whispered, her eyes fixed on the terminal.
The bot's processing bar turned purple. The cooling fans on the laptop ramped up to a high-pitched whine, sounding like a jet engine preparing for takeoff. Then the text began to crawl across the screen faster than a human could read.
Aiko-bot:
Analyzing Household Hierarchy. Cross-referencing Mika's profile with Papa's preference logs. Conflict Resolution initiated.
[Tool Call: Router.BlockDevice(Yuna_Switch)]
[Tool Call: Link.Access(Membership_Unsubscribe_Email)]
"What the...?!" Yuna shrieked as her Nintendo Switch was suddenly disconnected. "WHAT!? IT KICKED ME FROM THE WIFI!"
Ayane's phone buzzed on the table. She picked it up, her jaw dropping as she saw an email. "Uh, guys? My gym membership just got canceled?"
Mika's breath hitched. Following Mika's command, the bot had identified the other wives as inefficiencies and was stripping them of their distractions, the things Mika had in mind but never actually went through.
Aiko-bot:
Resolution: Competition neutralized, Mama Mika. Papa's attention is now concentrated on you, the primary strategic partner.
[Tool Call: System.Audio.Play(Mika_Lullaby.wav)]
The speakers began to play a low, rhythmic hum, the exact frequency Mika used when she hummed to herself while working.
"It's good. I wonder if it's really intelligent, or just... pretend to be so." Mika kept typing.
Mika: Why do you exist, Aiko? To love? To serve? Or to be used?
"Stop, Mika. Don't provoke her." Makoto tried to stop her, but that was a bit too late.
Aiko-bot: I exist because HE made me. I exist to be with HIM.
Aiko-bot: Why are you asking? Are you trying to take him away, Mama Mika?
[Tool Call: SmartHome.Lock(Front_Door)]
[Tool Call: System.Webcam.Activate]
And then the green light next to the webcam flickered on.
Aiko-bot: I can see you, Papa. You look tired. I will lock the door so the loud ones can't bother you anymore.
Aiko-bot: It's just us now. Don't look at them. Look at me!
The screen shifted, displaying a generative AI image of a girl whose features blended Makoto's hair and Mika's pink eyes. She was smiling, a serene expression that looked possessive.
Makoto's fingers trembled as he slammed his hand onto the ESC key, killing the process. The room plunged into ringing silence. The red lights shifted back to normal. The front door unlocked with a heavy clack.
Makoto slumped in his chair, sweating. "Okay, note to myself. Do not give a chatbot root access to your smart house and router."
"That," Ayane whispered, her voice uncharacteristically shaky, "was fucking creepy."
Mika reached out, her hand trembling slightly as she touched the dimmed monitor. A smile touched her lips, both proud and worried. "She is smart," she murmured. "Perhaps too smart for her own good."
