Chapter 129 My Ultimate Erotic Magic Tool ③
Edited by: Kanaa-senpai
An opinion exchange meeting for new products. Aerith from the Garou Merchant Guild¹ began to express her thoughts while I and Satsuki, the Court Mage, watched over her.
”Master, you have developed many products up to now. Various aphrodisiacs and lotions, of course, but also a wide variety of dildos and products with vibration functions. The ‘Anl-series’ product group was released the other day, and now we have this ‘Piston Machine’² and the ‘Ugo-Ugo Ddo-Buddy’³. Especially this ‘Piston Machine’…” Aerith said.
Coming from Aerith, who claims to have purchased every single item in our shop, these words carried significant weight. Thinking back on it, I really have developed a lot of things.
”I thought that these products might eventually converge into one. At this point, I’ve become a bit greedy, haven’t I? The combination of the ‘Piston Machine’ and the ‘Ugo-Ugo Ddo-Buddy’ seems feasible. I wonder if it’s possible to add a vibration function to this…” Aerith continued.
Aerith was cutting straight to the core. Indeed, functional integration is a path I have been aiming for. I thought the first ones to be realized would be the ‘Tremble-Ddo-Buddy’⁴ and ‘Hot-Hot Ddo-Buddy’⁵, though. And ultimately, I am envisioning something even further beyond.
It was a story I once told Lily, my experimental slave, and one I shared with Satsuki a short while ago. I might have mentioned it to the other employees half-jokingly as well. They say sharing a vision is important for a startup company, after all.
”Or perhaps, would it be possible to increase the number of ‘Ddo-Buddy’⁶ units that can be mounted on the ‘Piston Machine’ to two? A ‘Dual-Hole Piston Machine.’ I cannot imagine that the two creators—that you, Master—have not imagined what someone like me can easily conceive,” Aerith suggested.
Yes, if one knows of the ‘Piston Machine,’ it is a future that naturally comes to mind. Satsuki, who already knows the details, is glancing at my expression. It is the story of a dream I envisioned back when I first started crafting adult magic tools.
’Ddo-Buddy’ in one year. ‘Tremble-Ddo-Buddy’ and ‘Hot-Hot Ddo-Buddy’ in five years. The ‘Anl-series’ product group over ten years. The ‘Piston Machine’ and ‘Ugo-Ugo Ddo-Buddy’ in twenty years. And beyond that, a single point of ultimate attainment.
The bottlenecks I originally considered have ceased to be difficult technologies within this past year. Stable management, materials found by chance, and the support of many customers and comrades. Thanks to these, the magic tool that was once a distant dream is already within reach.
At this point, I don’t think anyone will overtake me, nor will the dream end as just a dream. Indulging in deep emotion, I decided to start telling the story of that dream.
”For example, a dildo that vibrates at the touch of a button.”
”…!!” Aerith and Satsuki gasped simultaneously.
Hearing the first sentence, Aerith and Satsuki straightened their posture. They realized I had begun to speak of the ‘Ultimate Adult Magic Tool.’
”For example, a dildo with the warmth of human skin.”
”…?” Aerith wondered.
”…!!” Satsuki gasped.
Aerith doesn’t know about the ‘Hot-Hot Ddo-Buddy’ yet. But since we’ve come this far, it should be fine to tell her. She isn’t the type to go blabbering around if I tell her to keep it quiet later.
”For example, a dildo that squiggles and wriggles on its own inside the canal.”
”…” they both remained silent.
They look at the ‘Ugo-Ugo Ddo-Buddy’ still attached to the ‘Piston Machine.’ Before the integration phase, I thought this would be the most difficult product to develop.
”For example, a dildo that automatically penetrates the canal or the rear on its own.”
”…” they continued to listen.
Needless to say, this refers to a ‘Piston Machine’ with expanded functions, the very ‘imagination’ Aerith spoke of earlier. I plan to start development as soon as the current ‘Piston Machine’ is completed.
”A dildo that possesses all of those functions simultaneously, allowing you to switch and combine them however you like with a single fingertip.”
”…!!” they both gulped.
The way they look at the ‘Piston Machine’ changes. This thing is still unfinished, and even when it is, there is still more to come. Just like me, the two of them are looking toward that ‘beyond.’
In truth, there are other magic tools I’ve envisioned, such as the ‘Nple Clamper,’ the ‘Uterine Massager’⁷, or ‘Slime-kun Who Dwells in a Woman’s Arse.’
”We can envision similar ‘ultimate forms’ for products other than dildos as well, right?”
”…!!” they reacted again.
For things I haven’t developed yet, there are things like ‘Nipple-Lick-Lick’ or ‘Nipple-Suck-Suck.’ If possible, I want to make these into magic tools where you can freely switch and combine them with vibration functions.
”Furthermore, a composite machine of ‘Ultimate’ and ‘Ultimate.’”
”…” they waited in silence.
Or perhaps something even higher, like the High-Performance Intercourse Automata, the Super Sex Automata⁸ ‘Dutch Husband’⁹. Nowadays, I feel like it might be achievable someday, but well, that is truly a story for the distant future. Probably.
”The above is, well, the ‘dream’ I told Lily when I first started the ‘underground business’ of this magic shop, Harvest¹⁰.”
Aerith and Satsuki listened to my foolish story to the end with solemn expressions. It was the same expression Lily and the others had back then, and it makes me think I’ve been blessed with good comrades.
I took a breath and closed my eyes. They didn’t speak either. For a while, we were immersed in the sight of that ‘dream.’ Well, generally speaking, it’s a sight that should probably be called a ‘lewd dream’ or a ‘nightmare.’
”Does this answer your question? Aerith’s imagination was mostly correct. However, there’s more beyond that.”
”To think that such a grand plan existed for these products…” Aerith said, her eyes sparkling.
”No matter how many times I hear it, it’s mind-boggling, and such a stupid idea. I mean, just how much lewdness were you thinking about…” Satsuki added with a sigh, though she looked excited.
Aerith with her eyes sparkling, and Satsuki looking exasperated yet thrilled. Well, more than half of it consists of ideas from the lewd people of my previous world. I’m glad they developed such a wide variety of adult goods.
But the reason I put it into practice, thinking that I could truly make even more amazing things in this world, is partly due to my own lewd heart. Also, it’s because Lily was just so sexy.
”No, well, it was a youthful indiscretion, or rather… I told her that if development and sales proceeded smoothly, we would surely reach that point in thirty years, so I asked her to stay with me until then. Thinking about it now, I feel like a terrible man…”
It wasn’t that long ago, but back then, I felt like I couldn’t keep going unless I said things like that. As I spoke poignantly, the two of them looked at each other with complicated expressions.
”I’m feeling quite jealous,” Aerith muttered.
”Indeed…” Satsuki agreed.
”Eh?” I blinked.
”I believe Lily-san was happy when she was told about that ‘dream.’ Regardless of whether that dream comes true or not,” Aerith said.
”Even I’m a little envious. Well, in reality, it’s something I can only say now that it’s been realized to some extent,” Satsuki added.
They say it’s quite ‘hot’ between us. Yeah, well, I guess that’s how it is… I’m starting to feel a bit awkward, so let’s bring the conversation back to something more grounded.
”So, what was it again? We were talking about whether there were any other concerns, right?”
”That’s right. I’ve heard what I wanted to ask, so all that’s left is that the ‘experiments’ seem like they’ll be difficult…” Aerith noted.
”Ah, yeah. That’s true…”
For this new product, the ‘Ugo-Ugo Ddo-Buddy,’ it’s fine to just try it out a few times as usual, but for the ‘Piston Machine,’ there are many combinations that need to be ‘experimented’ with.
There are three piston speeds: ‘low, medium, and high.’ Then there are the special ‘Ddo-Buddy’ types like ‘Bumpy,’ ‘Drill,’ ‘Craggy,’ ‘High-Ridge,’ ‘Tremble,’ and ‘Ugo-Ugo.’ Each ‘Ddo-Buddy’ also comes in different sizes. We can omit some by narrowing down the sizes that can be set, but it’s still a lot of work.
Furthermore, when you consider the combinations with our other products—various aphrodisiacs and lotions, as well as the ‘Nple Clamper,’ ‘Uterine Massager,’ and the ‘Anl-series’ product group—it seems like an infinite, staggering amount.
What’s more, Lily, who is in the middle of baby-making, cannot participate in the ‘experiments,’ and I can’t ask too much of the other members because it would stall their work. Even though Aerith here and Lady Tina Badcage decided to help out a while ago, we’re short-handed. No, we’re short on canals.
”Well, I guess we’ll just move forward little by little on the days Aerith and Tina can come…” I said.
”That’s right. I will also do my best to visit on days other than when major customers are coming,” Aerith replied.
”Um, about that…” Satsuki started.
”Hmm?” I looked at her.
”I’ve been thinking about this for a little while now…”
While Aerith and I were consulting, Satsuki, with her head down, spoke in a small voice.
”I… I think it would be most efficient for the ‘developer’ to perform the ‘experiments’…” Satsuki muttered quietly.

Summary:
The protagonist discusses the future of his magic tools with Aerith and Satsuki. He reveals his long-term ‘dream’ of creating an ultimate, all-in-one adult magic tool that combines all existing functions. While the complexity of the vision impresses his companions, the practical challenge of ‘testing’ all these combinations remains. Satsuki, despite her usual reservations, ends by suggesting that she, as a developer, should participate in the experiments.

Character Insight:
This chapter highlights the protagonist’s ambitious vision, showing that his shop is built on more than just immediate profit—it’s driven by a legacy of R&D goals. Aerith shows her deep loyalty and business acumen by predicting the path of integration. Satsuki’s final suggestion marks a significant step in her character growth; she is moving from a reluctant collaborator to someone willing to personally ‘sacrifice’ her body for the sake of ‘efficiency’ in their shared work.

Behind the Scene:
The concept of ‘Ugo-Ugo’ (squirming) and ‘Ddo-Buddy’ reflects the evolution of Japanese adult toy innovation, moving from simple static shapes to complex, automated mechanical movements.
