Chapter 399 Wriggle Ddo-Buddy ②
Edited by: Kanaa-senpai
For a while after that, I was completely absorbed in developing the “Wriggle-Buddy”¹ (working title). This time I’d settled on a standard rod shape, but I couldn’t stop wondering: what about other forms? Or different sizes?
I also had to pinpoint exactly what triggered the undulation. As it stood, the movement was way too aggressive. If it started thrashing like that inside a woman, it wouldn’t be a toy – it would be a hazard. I needed a way to throttle the intensity.
Then there were the safety checks. Was it hypoallergenic? Was it safe for sensitive tissue? Could it survive the high-temperature, high-humidity environment of the v**inal canal over long sessions?
After exhaustive testing, I finally finished a temporary prototype. Using the same logic as the “Tremble-Buddy”², I treated the device with “Pleasure-Aid Coating” – a mix of Red Slime essence and Akanashi sap. Once it hardened over the core, the problems vanished.
The coating acted as a dampener, keeping the wriggling under control while protecting the internals from moisture. Finally, I rigged a power switch using a strand of high-tension Caramel Spider silk. One click, and the whole thing came to life.
The result was a device that writhed and pulsed with a life of its own, stimulating the user in ways a static toy never could. But explaining the mechanics only goes so far. It was time for a live demonstration.
”So, is this the ‘new project’ you’ve been using to ignore us?” Miss Suu asked.
”I wasn’t ignoring you, I was – “
”You were neglecting us, weren’t you?” Marm interrupted. “This big sister was starting to worry that Kento had already grown tired of her.”
The two of them cornered me on the bed in the basement of the manor. Suu, the stunning cat-kin secretary from the Beast-person Association, and Marm, the receptionist from the Adventurer’s Guild, pressed in from either side.
This new product was a massive bargaining chip for the North-South Trade Route negotiations, and I needed the Association and the Guild on board. To get their seal of approval, I needed their expertise. There was no one better for the job.
Still, they were right. I’d been so buried in R&D that I’d neglected them. I felt a genuine pang of guilt.
”We aren’t actually angry, you know,” Suu whispered, her body heat radiating against my arm. “It’s just… well… you know.”
”I try to be the understanding type,” Marm added, leaning in close. “But even I have my limits, Kento.”
They didn’t need to say another word. The two of them were perfectly in sync, likely thanks to Lily. My love-slave had apparently been hosting “study sessions”³ while I was away. Even the Queen had been sneaking through the tunnels to join them. I was dying to know what they talked about during those nightly meetings, but they wouldn’t budge.
”It’s educational, fun, and a great way to relieve stress,” they told me. It seemed professional women in this world carried just as much tension as those back home. Well, that was my target demographic, after all.
”So? Show us what it does,” Suu said, her tail idly brushing against my waist.
I reached for the base of the Wriggle-Buddy and clicked the switch. The device began to whir, its shaft dancing in a rhythmic, sinuous motion. The two women stared at it, their breathing turning shallow.
”Oh… I see,” Suu murmured.
”Wow,” Marm whispered.
They understood immediately. As the two women pressed their feverish bodies against mine, I felt my own heart start to race. They reached out, their fingers tracing the writhing shaft as if it were the real thing. They were already imagining how it would feel inside them, their breaths hitching in soft, shaky gasps.
They adapted to the “new toy” with frightening speed. They teased the underside of the device, stroking the vibrating surface with slick, practiced movements while looking up at me with heavy, expectant eyes.
If they were going to look at me like that, I had to respond. I pulled Suu close, her body quivering with a delight that was almost tactile. I leaned in, and before I could say a word, she claimed my lips in a deep, wet kiss.
”Mmm…!” Suu moaned, her mouth sliding against mine.
”Must be nice,” Marm whispered against my neck. “I want a turn too.”
While Suu lost herself in the kiss, Marm’s hand wandered down to my crotch, stroking me through my clothes with the same expert rhythm she’d used on the toy. Swayed by her touch, I turned to her. Marm met me halfway, her lips pulling mine into a hungry, messy exchange.
”Mnh… haah…” Marm gasped between kisses.
”Aww, she stole him,” Suu teased.
The roles reversed. As I kissed Marm, Suu began to trail her tongue along my neckline. Realizing Marm was no longer holding the toy, Suu reached down to take her turn stroking me instead. Being sought after so intensely by these two made it hard to remember why I’d even brought the prototype out.
I was about to drown in them, but I forced myself to focus. I started peeling off Suu’s clothes. You might think I was giving in to my urges, but this was a tactical move. In this game, the first one to get undressed loses. They were already trying to slip their hands under my shirt, so if I wanted to “win,” I had to strip them both and put the Wriggle-Buddy to work.
”Ah… Kento…” Suu sighed.
”What, no ‘nyaa’ for me?” I asked.
”…nyaa…” Suu whispered, her face flushing as she glanced at Marm.
I didn’t stop there. I kneaded her breasts, watching as the tension leave her body until she was completely bare. Then I turned my attention to the other side.
”Do… do I have to nyaa too?” Marm asked.
”It definitely sets the mood,” I replied. “Whether you nyaa or purr, it makes me want to dote on you and discipline you properly.”
”…nyaa…” Marm whispered.
She probably didn’t realize she was essentially begging for it, but I wasn’t about to complain. I worked her clothes off until she was just as naked as Suu. The two of them lay there on the bed, side-by-side in their birthday suits, looking up at me with wide, shimmering eyes. It was a magnificent sight.
”Alright then,” I said, reaching for the toy. “Why don’t you two enjoy our shop’s newest arrival to your heart’s content?”
”…nyaa…” they both whispered in unison.

Trivia:
- The ‘Wriggle-Buddy’ is specifically developed as a negotiation tool for trade routes, not just for personal use.
- The harem members have formed a secret ‘study’ group that includes the Queen.
- The device uses Caramel Spider silk for its internal mechanical switching system.
- Kento views the s*xual encounter as a ‘game’ where the goal is to undress the others first

Character Insight:
Kento shows his ‘artisan’ side by focusing heavily on technical safety and material science. Suu and Marm demonstrate increased boldness, likely a result of the ‘study sessions’ mentioned by Lily.
—
Behind the Scenes:
The author frequently uses R&D segments to ground the fantasy world’s ‘adult’ industry in a sense of realism or ‘isekai’ technological advantage.

Notes:
• Suu – Secretary for the Royal Capital Beast-person Mutual Aid Association and a cat beast-person. Sample No. 19 in Kento’s report. She steps up as the first witness for the defense. Wears glasses and a tight suit.
• 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.
• Marm – The attractive, red-haired, tanned receptionist at the Adventurer’s Guild. She wears a uniform that emphasizes her ‘nice body.’ She is kind and acts like a supportive ‘big sister’ figure to Kento. Looks like Mirajane Strauss from certain series.
• 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.
