Chapter 80 Development Experiment One꞉ The Slimey Buddy
Edited by: Kanaa-senpai
”Everyone seems a little strange today, don’t they…?” Satsuki asked.
”Hmm, we’re just getting ready to test a new product,” I replied.
Even after the official transfer of the “Instant Heat Portable Magical Tool”¹ (a name we settled on for its functionality) from my hands to the military, Satsuki never stopped visiting the shop frequently.
Apparently, Your Majesty had given the order to “keep a close eye on Kento.” Satsuki told me this with an incredibly complex expression, but for the shop, we were simply relieved not to lose such a competent worker.
The reason she was tilting her head today was that the other members of the shop—specifically Lily, Tania, Laika, and Amelia—were all diligently working while oddly wriggling their hips.
”A new product…?”
”Yeah, this is it.”
”What is that…?” she wondered.
”It’s the ‘Slimey Buddy for Intestinal Cleansing’.”

Author:
I won’t describe the part where I squish the warm “Slimey Buddy,” heated by Lily’s body temperature, or the part where I say, “Look how much came out,” and bottle it for storage. I don’t want to completely alienate my readers (though it may be too late for that).

”Huh—!?” she bellowed.
”It’s the ‘Slimey Buddy for Intestinal Cleansing’,” I repeated.
”I heard you, you idiot!”
Satsuki’s retort² was quick as ever today. Looking at the jar containing the slime I’d pulled out, she shouted her reprimand, her face bright red.
”The… the rectal region… what exactly are you planning?! You pervert!”
”Well, the shop finally reached the stage where we could dabble in ‘anal-type’ products, which is great, but Lily and the others absolutely refused to do cleansing via enema,” I explained. “So, I devised a way to ensure simple, reliable intestinal cleaning with minimal discomfort.”
”A-A-An ‘anal-type’ product…?! Then, is everyone… right now…?!”
Oh, Satsuki looks like a cat that just saw the universe. Such a beginner’s reaction, just like Her Majesty. This world does have a culture of rectal intercourse, and this “Slimey Buddy for Intestinal Cleansing” is a product that borrows and improves upon the wisdom of our predecessors. However, it seems to be too stimulating for ladies raised in a greenhouse environment.
For the record, Lily and the others knew about that kind of predilection. That said, they hated enduring stomach pain from an enema, or—heaven forbid—if the cleansing was inadequate, having me see or smell their waste. The introduction of this “Slimey Buddy” was the only way they agreed to it.
”I’ll give one to you as a gift, Satsuki. I’d be happy if you could tell me about your experience. It’s excellent for regulating your internal environment and is even effective for beauty,” I added. “Ah, and if you’re willing to be a test subject for other products, you’re more than welcome!”
”Rectal… rectal… rectal…”
Oops, it seems she doesn’t even have the energy to retort anymore. She wandered in a daze for the rest of the day and quickly headed home as soon as closing time arrived.
* * *
Later, in the living space (which doubles as the workshop) after closing. Today, for the first time in a long while, it was just Lily and me for product development time. Unfortunately, the rest of the members lacked the courage, so for now, they would only share their feedback on the “Slimey Buddy.”
”Alright, Lily, take off your clothes.”
”…”
”Lily?”
I encouraged her to undress as usual, but Lily stood still, her lips tightly sealed. Oh dear, was the ‘anal-type’ thing really that much of a problem…? As I waited for her answer in confusion, she finally spoke, her face flushed red, which was rare for her these days.
”I am your slave, so it’s fine. But Master, you should at least feel some apology for exposing a maiden’s private parts.”
”Ah, yes. You’re right… I’m sorry, and thank you, always.”
”If you don’t make it up to me later, I will run away from home,” she warned.
”Understood. I’ll spoil you with everything I have.”
Having received my promise, Lily boldly slipped out of her usual one-piece dress. As always, she wasn’t wearing underwear. She sat in a seiza position, completely nude, and regulated her breathing.
”So, first, about your experience with the ‘Slimey Buddy for Intestinal Cleansing.’ How was it, having it inside while you went about your day…?”
”At first, the feeling was very strange, but I eventually got used to it. There was no pain, but I could tell that something was moving around inside my abdomen, and sometimes it, um, peeped out from the exit, which was startling.”
”Ah, you worried you might have lost control?”
”To put it bluntly, yes, but please choose your words more carefully…”
Lily rubbed her thighs together as she said this. It seemed that taking off her clothes had brought back the unusual sensation in her lower body. Or perhaps she was simply feeling shame at the frankness of the discussion. She must know that when she blushes so obviously, it ignites something in me.
”Then, can you turn around so I can see the area?”
”…”
Lowering her head and glaring at me from behind the curtain of her pink hair, Lily slowly turned her back to me. The line of her spine was visible, tracing down to her round, cute hips. She pushed them out, exposing the slightly moist area and the rectal region, which twitched faintly.
”Ohh!”
”What is there to cheer about…? Haven’t you seen it countless times…?”
”No, I mean, when you thrust it out like that and tell me I can do whatever I like, it naturally gets me excited.”
”Oh, honestly…”
Besides, Lily is precious because she can still feel embarrassment even though I’ve already developed every part of her body. I happily leaned in to give her a light, playful kiss on her hip. Even though this is a regular occurrence, she still flinched, which was adorable.
I made a point of making soft sounds, lightly sucking, and brushing the area with my tongue and front teeth. Next, I ran the five fingers of both hands lightly over the skin, barely touching. Thanks to the beauty lotion or her constant efforts, her skin felt plump and soft, like a water-filled dumpling, making me want to touch her forever.
”Master…”
”Hmm, what is it?”
”Please hurry, before my resolve wavers…”
”Hmm, just a little bit more…”
”Enough!”
I rubbed my cheek against the hips she offered. I grasped them softly with both hands, gently spreading, then squeezing them together, kneading them playfully. Lily’s soft tissue changed shape at my will. With every movement, her body quivered slightly.
Whew…
Ugh…
Satisfied, I sat up and parted her hips to examine the center. Oh, the area was swollen and open, becoming quite a sight. The excessive moisture dripped onto the floor, like a dog drooling before a meal.
The urge to focus on that area was strong, but the main dish today was the area above it. I shifted my gaze to the tightly closed rectal opening. I had seen it many times, but this might be the first time I was staring at it so intently. I could almost count every single wrinkle…
”Oh!”
As I stared, the external sphincter muscle bulged slightly, and the “Slimey Buddy for Intestinal Cleansing” peeped out. Through its translucent body, the expanded muscle and the pinkish internal lining were clearly visible. It was truly a marvel of the human body.
Oohhh…!
No…!
It was a faint, fragile voice of refusal, one I hadn’t heard from Lily in a long time. She kept her face down, offering her hips, with the edge of her ear visible through the gap in her pink hair, completely red.
The “Slimey Buddy” poked out and retracted whenever her body trembled. The constant movement—protruding and withdrawing—made her tremble further.
Of course, Lily’s rectal opening repeatedly opened and closed in response, and the sight of its expansion and contraction was strangely fascinating. I silently wondered how strongly the muscles would clench if I were to insert something there…
While Lily remained silent, I reminded myself that the goal was product development. I collected myself and asked her mercilessly.
”Lily, it keeps coming out and going back in. What sensation is that? Does it give you any sexual pleasure just from this?”
”…I don’t know. There’s a sensation, but I wouldn’t call it ‘pleasant,’ not really.”
”Even though you’re shedding all this moisture?”
”T-That is…! That is because of the situation—because you’re watching me!”
”Hmm, is that so…”
Lily gave her honest feedback, albeit hesitantly. She felt ashamed, but she seemed to be trying her best to treat this as work. I thanked her and stroked her hips, but she simply let out an angry, muffled sound.
”Can you push it out now?”
”P-Push it out…?! What a thing to say!”
At my question, Lily’s rectal opening tightened and clamped shut. The hurried retreat of the “Slimey Buddy” back inside was oddly comical.
”But I have to hear about the feeling of expulsion…”
”T-There’s a way to phrase things, isn’t there?!”
”It’s alright. Even if the real thing came out, I would still love you, Lily.”
”That’s not the point!”
Ah, she really sounds angry now. I realized this but knew the “development” must continue. To appease her, I gave her hip another kiss, but she desperately squeezed her muscles, refusing to let the “Slimey Buddy” escape.
If she could control it with her will, was the protruding and retracting just now perhaps a deliberate show for me…? A clever man, I chose not to say it aloud. I’d chalk it up to the “Slimey Buddy’s” whims.
”Hmm, if you resist too much, I’ll have to force it out of you.”
”Eh?! Hiah!?”
I ran my tongue lightly over the area around her rectal opening, almost like a mother cat encouraging a kitten to relieve itself. Thanks to the “Slimey Buddy,” Lily’s intestines had been safely cleaned, so I wouldn’t mind touching it directly.
However, that wasn’t the case for Lily. When I traced the area with my tongue and tried to breach the center with the tip of my tongue, she quickly agreed to a compromise.
”I-I understand! Please, anything but that!”
”Oh, good. Thank you, Lily.”
I moved my face away from her lower body and urged her to release it quickly. She glared at me resentfully, but well, this was her reward. I playfully patted and stroked her hips. Finally resigned, Lily began to apply a slight pressure to her lower abdomen. The rectal opening began to rise, and I could even see the vaginal opening clench in effort.
Ugh…
Hanging her head, Lily pushed her hips out, trembling slightly as she strained. The raised rectal opening stretched and widened radially. It finally opened a little, and the “Slimey Buddy for Intestinal Cleansing” tentatively poked its head out.
But it didn’t fully emerge. It remained just beyond the external sphincter, showing its translucent surface as if it didn’t want to leave its comfortable place inside.
”Why…!?”
Frustrated by her inability to expel it, Lily’s voice trembled. Was it because the inside of Lily’s intestine was too comfortable, and it didn’t want to come out? No, the host should be able to expel it if they put their mind to it.
”Lily, you can use your hands for support, but lift your hips a little and try to point the opening downwards.”
”Y-Yes, Master…”
Lily followed the instruction, getting onto all fours and tilting her pelvis back. With a soft, wet sound, the tip of the “Slimey Buddy” emerged from the opening.
”No! I didn’t mean to make a sound!”
”I know. That was just the air escaping that went in,” I reassured her.
As I stroked her back to calm her, I felt a faint dampness of sweat on my palm. It seemed she was trying very hard to push. With its head out, the “Slimey Buddy” slowly began to be expelled.
”That’s good, keep going, you can do it.”
Hauu…♥
Her low groan began to take on a hint of pleasure. She must have been getting a euphoric sensation from the abnormal experience of such a volume passing through the opening. It’s okay, the pleasure accompanying the expulsion is a physiological reaction, there’s nothing wrong with it.
Ahh…♥!
With a low, dragging sound, the “Slimey Buddy” was slowly extruded, widening and rubbing the opening as it went. I watched the thick body slowly pass through Lily’s muscles.
Oooohh…♥♥♥
Finally, with a soft splash and a deep sound, the entire “Slimey Buddy” was expelled.
”Hah! Hah!”
Before us was the pink, gaping opening, and a coiled pile of the “Slimey Buddy” gathered below. It’s fine; no matter how much it resembles something else, it’s just translucent, jelly-like slime. The optional scent is a refreshing floral aroma.
”There, there, you did so well. You’re such a good girl for pushing it out successfully.”
”I’m going to punch you…”
Lily glared at me as I stroked her back, and she spat out that line.

Summary:
Kento’s newest product, the ‘Slimey Buddy for Intestinal Cleansing,’ totally baffles Satsuki, but she can’t stop him. Later, Kento conducts an up-close and personal product test with Lily, who is super embarrassed but goes along with it, providing vital feedback on the slime’s movement and expulsion for the next stage of development.
—
Character Insight:
Lily’s deep loyalty to Kento is clearly shown when she overrides her intense embarrassment and discomfort to assist him with product testing, but she still asserts her emotional boundaries, demanding an apology and future pampering. Kento’s focus on product function often blinds him to the emotional toll on his assistants.
—
Behind the Scene:
This chapter is the launch of a new product category (‘anal-type’ goods, heavily sanitized here) and re-establishes the dynamic between Kento and Lily as master/test subject, which drives much of the series’ character interaction.
—
T/L:
The Japanese for the product name is 携帯式瞬間発熱魔道具 (Keitaishiki Shunkan Hatsunetsu Madougu), which literally translates to ‘Portable Instant Heat Magic Tool.’¹ ↩
² refers to the straight-man role in a comedic duo, often delivering a verbal punch or correction to the other person’s foolishness. ↩
Notes:
• Satsuki – A talented Court Mage who was forced to analyze the shop’s adult magic tools. Miranda’s granddaughter. Now she’s the new worker at Harvest, a development she finds both humiliating and surprisingly fulfilling due to the rapid progress in her research under Kento’s guidance. Has long black hair, palace mage robe, and staff.
• Kento – The owner of the magic tool shop ‘Harvest,’ which discretely sells adult goods. He’s a former overworked, ordinary salaryman from modern Japan who was suddenly transported (isekai’d) to this fantasy world. He has dark hair and an unremarkable appearance, typically wearing a plain, slightly suspicious-looking shop owner’s clothes looks like Kazuma Satou from certain series. He has a minimal amount of magic power, enough to craft his specialty items.
• Amelia – The Sister of the Church of Demon-Subjugating, who usually buys from Kento, has light blue hair.
• Laika – The beastwoman dog.
• Tania – An Elf adventurer who, despite her race’s reputation for low sex drive, is secretly quite passionate. She initially seemed ‘wasted’ (emotionally dry) to her friend Raika, but was easily introduced to the pleasure-items sold at ‘Harvest.’ She is easily embarrassed and attempts to maintain a dignified facade, despite her recent, frequent purchases. She wears practical but light armor over a simple cloth tunic and short pants, highlighting her grace and agility. Her primary relationship is one of friendly senior-junior with Raika.
• Lily – the sl*ve and primary experiment subject for the magic shop, ‘Harvest.’ She has striking pink hair, Blue eyes, medium breasts, which the Protagonist associates with being ‘wanton’. She has a working knowledge of magic, which she kept hidden from the slave trader.
