Chapter 400 Wriggle Ddo-Buddy ③*
Edited by: Kanaa-senpai
Now then, which one will be first? A clinical(?) experiment of our shop’s new product, “Wriggle Ddo-Buddy¹.” While looking down at the two of them lying side-by-side on the bed with their crotches spread open, I muttered such a thing in my heart.
One is the beast-person beautiful secretary of the “Beast-person Association²,” Suu-san. She is always a crisp “capable woman,” but on top of the bed, she is a person for whom suspicions have begun to emerge of being a “funny big sis” who prefers “Nyan-Nyan Play (she/her)” [nyan-nyan-puray]³. Her tail, with a high-class feel and light purple fur that also looks silver, sways back and forth between her crotch, looking voluptuous.
The other is the beautiful receptionist of the “Adventurer’s Guild⁴,” Marm-san. A person whom I was greatly indebted to during my adventurer days, and whom I want to call “big sis” even though she should be younger. Dyeing even her brown skin red up to her red hair, she shyly cries “Nyaa~” imitating Suu-san.
I faced them, carrying two “Wriggle Ddo-Buddy” units. The two of them, as if they had practiced (actually, they might be practicing in a so-called “study group”), opened their legs in a wide stride, and the legs on each other’s side are voluptuously entwined.
In addition to the contrast between white skin and brown skin, here are the pink colors of the mucous membranes that look very similar. The wet v**inal holes are Grand Duke-ly opened and reflect the light glisteningly, and the labia are wriggling twitchingly as if wanting something. The erect clitorises peeked out slightly from the foreskins and were thrust out toward me as if they wanted to be bullied.
”…Erotic.”
””…nn-h♡♡♡! “”
At the words I accidentally let slip, not only Marm-san, who was already red, but even Suu-san dyes her cheeks with shame. However, considering that, it’s not like they’re displeased, or rather, I could see the v**inal holes happily making “paku-paku” mouth motions, tightening the inside “kyun-kyun.”
As a maiden, I don’t not think “how is that reaction,” but there’s no way I’m not happy to be long-awaited. It seems that thanks to being occupied with research, I’ve made them store up quite a bit of desire, so I must have them be fully satisfied.
”Well then, shall we start the ‘experiment’ begin?”
”…♡♡♡”
The two of them, no longer saying anything, swallow their saliva looking at the “Wriggle Ddo-Buddy” being gripped in my hands. I straddle over the overlapping legs and aim for the left and right v**inal holes.
Kuchu…. If I apply the tip of the “Ddo-Buddy” to each of their cracks, lewd water sounds can be heard in stereo. Nuchi, nuchi…. Sliding the “Ddo-Buddy” along the cracks, I make the love juice cling to the blade(?).
”Haa, haa…♡♡♡”
”Nn…♡♡♡”
Whether they are already starting to feel pleasure, the two of them are pouring their gazes at their own crotches with thick, entranced eyes. At those concentrated expressions, my desire also swells up muku-muku.
Guchu, guchu, nucha…. The sensation of soft flesh transmitted through the “Ddo-Buddy.” The two’s v**inal holes increase the flow rate, and low-viscosity love juice seeps out toro-toro one after another.
”Well then, I’m going to insert it, okay?”
”Yes…♡♡♡”
”Nn, please, hurry…♡♡♡”
Marm-san’s sweet entreaty in mind, I aim at the v**inal opening with the glans part of the “Ddo-Buddy.” If I push it in with a little bit of force, it gets taken into them zubu-zubu.
”Ah, ah…♡♡♡! “
”It’s coming in…♡♡♡! “
Making their thighs furu-furu and while making their waists tremble piku-piku, they invited the “Ddo-Buddy” into the v**ina. Whether to endure the pleasure or to provoke me, they crossed their arms under their breasts together, and on top of that, two colors of soft flesh are jiggling purun-purun. And then, at that time….
”Aah♡♡♡!?”
”Eh? Marm-san!?”
In the v**inal hole where Marm was enjoying the taste of the “Ddo-Buddy,” she suddenly bounced her waist and let out a high-pitched cry. Suu-san, who has her legs entwined, looks at her surprised by that reaction.
”Ke, Kento-kun♡♡♡! To suddenly turn on the switch is a foul, right…♡♡♡!? Ah, ah, inside the v**ina, ah…♡♡♡!”
At Marm’s words, I realized the corners of my mouth were rising despite myself. While she says things as if blaming me, I can tell her eyes are pleading “do it more♡♡♡.” However….
”Kuku, I haven’t done anything. Actually, this ‘Wriggle Ddo-Buddy’ has an interesting characteristic…. When the v**inal pressure goes above a certain level, the switch turns on on its own.”
Yes, the “Mystery Rod” that became the raw material for this “Wriggle Ddo-Buddy” originally had the characteristic of beginning to writhe when pressure was applied. Depending on the method, it was possible to make it so it doesn’t operate on its own by methods such as making the outer skin thicker, but I dared to choose to leave this characteristic. Of course, it’s for times like this.
”Eh…♡?”
”That means… Marm-san.”
”Yeah, Marm couldn’t endure it and ended up ‘mogu-mogu’ the ‘Ddo-Buddy’.”
”Th-the way you say it! It’s, it’s just that strength went into it on its own! Wait, ah♡! This, it won’t stop♡♡♡!?”
By the way, I have also thought of the possibility that the “Ddo-Buddy” might go out of control because the v**inal pressure cannot be suppressed like this. If you pull the switch to the opposite side, the internal metal parts will brace themselves and make it so pressure is not applied to the “Mystery Rod.” I stop the operation of the “Ddo-Buddy” that is pierced into Marm-san.
”Ah, it, it stopped…?”
”I see, it can be operated by v**inal pressure or by the switch. Ei♡! Ah, it started moving…♡! Certainly, it’s interesting, but I feel like it’s a function that will eventually stop being used…. No, could it be just right for practicing controlling v**inal pressure…?”
”Nn, well, it’s something like that. I just wanted to see the two of you’s surprised faces, though.”
”Geez, Kento-kun!?”
Seeing my operation, Suu seemed to understand the usage method immediately. That she is checking the movement of the “Ddo-Buddy” by increasing or loosening the v**inal pressure is transmitted through the sensation in my fingertips.
”For now, it’s like this, I guess. After this, I want you to show me how the two of you use this.”
”Yes, I understand…♡”
”…erotic♡”
After explaining the usage method to some extent, I release my hands from the “Ddo-Buddy” and take distance from them. A product is something that exists because of the user; it is important what kind of reaction the person actually utilizing it shows. …That is half a pretext, and of course, the true intention is because I want to see the two of them in a state of shameful indulgence. Eventually, the two of them respectively began to concentrate on the “Wriggle Ddo-Buddy.”
”Nn, aah♡♡♡! A-as I thought, it moves on its own…♡♡♡ Ah, ah, right there…♡♡♡!”
”Nn, nn♡♡♡ The unpredictable behavior is good…♡♡♡ It’s also frustrating, but it’s like having someone else move it for me…♡♡♡”
From the fresh experience, the breathing of the two gradually becomes rough and hot. At the state of the two of them vulgarly seeking pleasure, I unintentionally swallow my saliva gokuri. From the insertion part which is being made to deform guni-guni by the wriggling “Ddo-Buddy,” love juice that has become droplets is overflowing.
”Ah, if I release my hands, it ends up like this…”
”If there’s nothing to hold it down, it will be like that. If you fix it to your panties, I think you can enjoy it hands-free.”
”I see, that seems good…♡”
”Ah, ah♡♡♡ I think I’ve gotten used to it…♡♡♡ Inside my stomach, it’s amazing…♡♡♡”
”If you’re enjoying it, then more than anything. Probably, it feels good even if you move it at a shallow position.”
”Ah, really, a different spot…♡♡♡ Ah, ah, ah♡♡♡!”
Suu, who tries various things while enjoying it, and Marm, who purely conveys the feeling of use. Generally, the reputation seems good. The sweat seeping into their skin jinwari expressed their level of arousal. Eventually, Suu notices a certain function.
”Oh…? Kento-san, could it be, but does this have one more stage of switch?”
”Ah, you caught me. I was hoping you’d just accidentally jam it in all the way…”
”Geez, Kento-kun! Don’t just do nothing but mischief!”
”Now, now, so, if you push this in, what will happen…♡?”
”That, of course, is a pleasure to look forward to after pushing it!”
