"Keeeee-boyyyyyy!" Kokichi sang as he hastily approached the Ultimate Robot.

Kiibo had just stepped out of Miu's workshop moments prior. There wasn't anything out of the ordinary in regard to an inventor drawn to a robot or the inverse, however, this time, it piqued the Supreme Leader's curiosity.

"Hey, hey hey! What did she do to ya this time, huh? Anything fun or secretive maybe?"

"U-uh…" Kiibo stammered, startled by the boy. Miu had, in fact, just installed something, an upgrade to something she'd installed previously. However… "Th-that's not really any of your business."

"Awwwww! So she did do something after all! It was only a guess, you know? Heh." The boy stepped back and crossed his arms before his mouth widened into a significant smile. "Judging from your reaction, it's also something secretive, isn't it? Suddenly, he leaned forward, positioning his head closer than necessary to the robot's. "Come on, come on! You can tell me! Would I ever spout confidential information?"

"You would. You literally have before." Kiibo said before he began to walk away, trying to simply ignore the problem as he usually did.

"Pshhh, oh you merely jest!" The boy said before he raced back in front of the robot, once again blocking his route. "Besides! Anytime I did, it was out of need! I know robots like you struggle with cognition unlike most humans, but surely you can understand that at least! Or, what? Did your creator, what was his name again? Eyedobushi? Not take that into account."

"Your levels of robophobia are so high I hate even looking at you." He said while trying to push past.

"Wait wait wait!" Kokichi spuriously pleaded with puppy-dog eyes. "Can I at least feel you? I still never got to experience that, you know! Or maybe guess what that woman added to you? We can think of it as a game if you want!"

"F-feel me?! That's inappropriate no matter the species!!" Kiibo cried.

"Oh, huh. It is, isn't it? Gee, I had no idea...so anyway! Can I? Can I?!"

"NO!"

"BOOOORING!" Kokichi shouted but thankfully stepped back with a huff. Afterward, he lifted a hand and placed it against his chin. "So it's down for me to guess, huh? Well I suppose that could be fun too. Now then, hmmm..."

Once again, Kiibo tried to leave the boy behind.

Fortunately for Kiibo, this time Kokichi didn't intercept him. Unfortunately, as a smirk spread across the Supreme Leader's face, the words that then came out of his mouth stopped the robot in his tracks all the same.

"Hey, do robots have dicks?"

It was a question he'd heard before, but now it was much more…prominent. He could've just left. He should've. But as he stood rooted in place, he just couldn't stop himself from speaking.

"N-no?"

"They don't, and they shouldn't," Kokichi agreed before he turned around and faced Kiibo's backside. "Yet from how big a whore that Ultimate Inventor is, coupled with your fluster when I first saw you, is the Ultimate Robot the first of its kind to have an extra, mechanical, appendage?"

Ultimately it was another bluff, but witnessing the robot's brief struggle to formulate a response following a lie he easily saw through, Kokichi knew his words were onto something.

"Th-that's…utterly ridiculous!!" Kiibo cried, and once again attempted to flee as he regained his bearings.

However, the other boy only needed to reach out and take one step forward for his fingers to wrap around his classmate's metallic arm. "Whoa, there! What's the hurry? If I'm wrong, you should tell me! I am wrong, riiiiiiight? Nyehehe!"

"Y-yes! You're wrong, like always!" Kiibo cried but was unable to hide the shakiness in his voice.

Kokichi's shoulders slumped before, in an instant, his snarky attitude turned dejected. "Wow, that was rude, you know? I'm not wrong all the time! I know being human means accepting being wrong sometimes, for example! Although, I suppose you wouldn't understand that." The boy's façade then disappeared as fast as it appeared, which allowed his expression prior to return, but now, with an even larger, mischievous, smile. "I also know that you're lying. Did you honestly believe such agitated speech could slip unnoticed by me?"

"What do you want, Kokichi?!" The robot demanded.

"I'm glad you asked!" Kokichi exclaimed before lifting his arms and placing both behind his head. "Simple really, I merely want to see and test it out!"

"I told you! There's nothing to test out!" Kiibo cried, growing more and more panicked.

"Still insistent on your easily exposable lies, huh?" The purple-haired boy asked with another giggle before he turned around. "That's fine, I can learn the truth from that inventor slut, instead." Afterward, it was Kokichi's turn to begin walking away.

"AHHH!" Kiibo cried. If he asked, or rather, intimidated Miu into telling, she might divulge more than she needed to. "F-FINE! I…she gave me…functioning male genitalia. Happy?!"

The Supreme Leader then spun around and ran back toward Kiibo, stopping closer than necessary to him with a cheery expression. "Seeeeee? That wasn't so hard now was it? Now that that's over with, how about accepting my latest proposal too? Let me test it out, pleeeeeease!"

"Wh-why would you want to?"

"No reason, except curiosity of course!" the boy replied. "It's not everyday machinery that gets dicks installed onto themselves, after all!"

The robot weighed his options. Either Kokichi would bug him about it for the rest of his days, or he'd tell the others, or both. Better to just show him, let him touch it a bit, and get it over with. "F-fine! But…let's go somewhere more secluded."

The boy's eyes glistened with joy and excitement. "What a good robot! Lead the way, Kee-boy!"

The boy walked around, with Kiibo peeking around to see if anybody could've been watching before they finally got to the back room where they'd found the original exit. Once inside, the two stopped, and he turned. "I will only show you if you don't tell ANYONE about it, alright?"

"Awwww, for real?" Kokichi replied with a pout but exhaled a moment later. "I suppose I can agree with that. Understandable that the Supreme Leader, me, should have privileges that mere peasants don't!"

The robot nodded. With a sigh, he reached behind his back, to the back of his neck, and pressed a single, small button. As soon as he did, a plate at his groin slid back, and a six-inch rod popped out, covered in what almost looked like living flesh. Kiibo had had to argue with the inventor not to make it ten inches, but even now, it was still quite long. The sight of it made the boy flush.

For the first time since the mischievous boy confronted the robot, he was silent as he stared down at the new object. Awkwardness permeated the room as seconds went by. But just as Kiibo opened his mouth to speak again, "Wooooooooww!" Kokichi exclaimed. "Perhaps I should begin calling that deviser the 'Ultimate Whore' instead? I didn't think she'd make it so big!" His eyes then flicked up to meet Kiibo's. "Did she make you use it on her already?"

"TH-THAT'S NONE OF YOUR BUSINESS!" He screamed as his face turned even more red. "A-and she actually wanted it even bigger. I had to talk her down to this."

"Heh, is that right?" Suddenly and without warning, Kokichi's hand shot forward as his fingers found their grip on the metallic shaft.

"AHHHH!" The boy cried as the mechanical sensors Miu had installed were fired off, simulating nerves. The robot's legs wobbled. "K-KOKICHI!"

"So this is what it feels like!" Kokichi, apathetic to his classmate's clear discomfort, cried in joyous amazement. "I wonder if this would cause more pain or pleasure if it were shoved into a woman's-"

Before he could stop it, a moan escaped Kiibo's mouth. As soon as it left, his eyes went wide and he shoved both hands over his mouth.

"Hm?" Kokichi asked, tilting his head slightly to the side. "Did I hear that right, Kee-boy? Is this addition sensitive to the touch?"

"N-no! I just…uh…" He tried to come up with a valid excuse.

"There's no need to be ashamed," the boy assured with a giggle. "Your secret is kept safe with me, after all!"

Under any other circumstance, Kiibo would've made another hurtful, but truthful, comment about Kokichi's inadequacy in keeping secrets. However, the embarrassment he felt at the current moment overtook any other emotion the robot had, which only increased along with his simulation when Kokichi slid his hand along the shaft.

"Th-this is…really weird, you know…" Kiibo said, hating that he was actually almost enjoying it.

"Tell me Kee-boy," Kokichi started in an ingenuous curious tone, entirely evading Kiibo's accurate statement, before he began to move his hand back and forth along the rod. "What do you feel when I do this?"

He already knew the answer to his own question, however, it gave him an 'excuse' to begin stroking and in turn, toy with Kiibo's emotions further.

"I f-feel…lots of…thiiings…" The boy groaned. He could feel the things Miu had designed him to feel. She'd been so proud of it that he couldn't say no, but now he was cursing her name in regret because of just how damn good it felt. "Gaaahhh…"

"Oh? Would you mind being so kind as to be more specific?" he inquired while continuing with a smirk.

"I-I haven't experienced this kind of stuff much, I don't know how to describe it! AHHHHH~!" He groaned. He knew he was coming close, all because of the little gremlin.

"Of course, robots don't have a need for these, after all. Althoooooughhh...the fact you're not struggling against my ever-so-gentle grip means you're enjoying this, riiiiiiight? Nyehehe!"

"I-I…y-you…g-gaaahhhhhh!!" He moaned as he discharged. White paste exploded from the slit at the front, as Miu believed that was the closest substitute for actual cum, which he'd had to convince her not to throw into his fake cock. It splattered all over Kokichi as he unloaded, his entire metal body shaking until he was emptied, and he collapsed onto his knees, panting.

"Oh, so that's what happens." Kokichi, this time genuinely, said to himself. Not even a second after he finished speaking though, his demeanor changed quickly and drastically. "HOW LEWWWWWD KEE-BOY!" Then, his calm persona returned again only another second afterward. "I'm sure 'Pinkie' will be happy to learn you're able to unload, that is, if she didn't already make you do so!"

Kiibo continued panting as Kokichi, now apparently bored with him, began to walk away. As he was almost out of reach, however, the robot reached out and grabbed his arm. As Kokichi looked back at him, confused, Kiibo couldn't believe the words that came out of his own mouth.

"C-can we do that again sometime?"

And that single sentence sent Kiibo down a path of weird self-discovery. While he never really came to like Kokichi, or love him in any way, he did have to eventually admit that the boy seemed to know what he was doing when it came to sex, somehow.

Miu was certainly happy with all the research data every time he had to come back to refill…which was often.
