The Necessary Equipment Is an Adult Toy
What are breasts?
They are the very first meal a person consumes upon being born. In other words, the source of life resides there, and that is why everyone naturally craves them.
Especially men—as the saying goes, "men are just boys who grew up"—they are born with a nature that makes them yearn for breasts at any time, in any place.
So, it was only natural that I couldn't tear my eyes away from the magnificent pair of peaks spread out before me, letting out a gasp of admiration.
"Oh, oh my……."
Geez, how can a person's breasts be this big?
No, it wasn't just the size that was special. Even at this scale, there was almost no sagging, and I could see with the naked eye that they still possessed incredible elasticity.
On top of that, feeling the texture I had experienced once before, my hand naturally began to reach out toward her chest.
And soon, my hand settled onto her breasts. The process was entirely subconscious, and as it turned into a kneading motion, I felt an uncontrollable ecstasy surging from my fingertips to every corner of my body.
-Squish, squish.
Yeah, I’m kneading them. These massive, bountiful breasts—a pair so grand that the term "Grand Canyon" wouldn't be an exaggeration, refusing comparison to any woman I’ve met so far—were being manipulated by my hands.
The way they sink deep when pressed, and the way they return to their original form the moment I release the pressure—this elasticity, this weight, this texture……. Haa, damn it. I want to suck on them with my mouth. Is it okay if I do?
Should I just go ahead and touch her pussy too?
"……."
But in the midst of that, I began to feel a sharp gaze.
When I looked up, I found myself staring directly at the owner of the breasts I was holding.
With an expressionless face devoid of emotion, she stared at me endlessly, without saying a single word.

"……."
"Uh, um. I’m sorry. It’s my first time seeing them this big, so without realizing it……."
Does she think I’m trying to trick her? I hope she doesn’t get defensive and ruin the contract or whatever.
"Understanding. I was the same."
Contrary to my anxiety, fortunately, she seemed to think nothing of my actions.
It seemed she considered it similar to when I touched her cock to make her ejaculate earlier. Thinking that, I cleared my throat to calm my excitement and lifted the two pieces of metal she had handed me.
"So, these are items engraved with a rune that causes a slight vibration, right?"
"Yes, but that’s all they can do."
Yeah, at first glance, they seem like useless items. If the output were higher, they might be useful somewhere, but with vibrations that barely make the skin tremble, they wouldn't be good for anything productive.
But how can a person live doing only productive things?
To soothe a weary and boring life, stimulation is necessary.
And what I held in my hand was, in its own way, a decent tool for providing such stimulation.
"So, how do I use them?"
"Um, to put it briefly, it’s for massage."
"Massage……."
Her gaze shifted to the vibrating metal lumps. They were small stones, barely enough to be held between two fingers. Naturally, one might think they lack the size and vibration to loosen up tense muscles.
"Can you loosen up the body with that?"
"Of course, you can't use it on areas with tense muscles like the shoulders or back. But for small, delicate parts, it should be more than enough."
"If I were to use it, for example?"
"Right here."
The place I aimed the metal at was her breasts.
I brought the metal to the protrusion at the center, and the faintly vibrating object began to stimulate her nipple.
Very faintly, but surely……. Yes, just like a 'rotator'—a sex toy I used in my original world.
"……Nipple massage?"
"It feels good when they loosen up. I'll keep rubbing it for a bit."
She didn't show any signs of refusal, so I figured it was fine to continue.
So, I kept rubbing the rotator against her nipple and spent some time watching her reaction.
I was aiming for the large protrusion at the center of her bountiful breast. As I focused on the areola, turning and pressing to apply stimulation, I noticed her body trembling, albeit slightly.
Even so, her expression remained blank, and her mouth remained silent.
"……."
"Do you feel something?"
"A little, the vibration on the nipple……."
"You're starting to react. I'll keep going."
"……Yes."
Was it her natural curiosity triggered by the fact that there was some kind of change? As I continued to caress her breast with the rotator, I noticed beads of sweat forming on her skin one by one as time passed.
And her face was slowly turning red, with small moans leaking from her lips.
"……Ugh."
She was feeling it. The expressionless artisan who knew nothing about sex until now was being unraveled by a mere piece of metal causing tiny vibrations.
"How is it? Does it feel good?"
As I asked her honestly and continued the stimulation, she replied shortly in a somewhat precarious voice.
"……I don't, really, know."
"I guess the stimulation isn't enough yet. Don't you want to try something more stimulating?"
"Something more, stimulating……?"
"Yes, for instance……."
My gaze drifted downward. The moment I locked eyes with the modestly closed, linear crack located there, the rotator in my hand began to move toward it.
I aimed for the small protrusion at the top of the parted crack. As I brought the rotator to the place that exists solely for the purpose of feeling orgasm, her body, which had only been trembling slightly until now, began to shake violently in an instant.
"Ugh……!"
Whoa, look at this. Despite having such absurd breasts, her erogenous zone was down there.
Feeling the freshness of that gap, I continued to stimulate her clitoris while holding her breast in my hand and sucking on her nipple with my mouth.
"Ah."
A faint gasp. Along with it, a question felt in the gaze directed at me.
"I tried it because I thought you needed stronger stimulation. How is it? It feels more vivid than just trembling, right?"
When I asked, trying to be a bit shameless, she twitched and shuddered as she gave me an answer.
"……Yes, I don't really know, but, I can feel it."
"Then, I can keep going, right?"
"Y, yes……."
There was no doubt, and the consent was given.
Then, all that was left was to drive her home.
-Whir, whir.
I continued to stimulate her clitoris with the rotator and caress her breasts repeatedly.
As I did, I could feel water flowing between her cracks, and the heat of her body grew even more intense, which was transmitted to me as well.
Heat boiled in her body, and her moans grew rougher.
"Haa, ah, ugh……."
As I felt her breathing grow more intense, my fingertips pressing against her began to exert even more force.
Almost at the finish line. Good, I’ll make sure you have a grand first climax right now.
"I'm going to stimulate you strongly once."
"W, wai……."
-Whirrrr.
"U, ugh……!"
Ignoring what might have been a plea to stop, I repeated the caresses. At the end, I pinched and twisted the clitoris that had swollen from the rotator's stimulation, and her head began to tilt back in response.
And—splat! With that sound, her love juice erupted violently.

"O, ohhhh~~~~♥♥♥"
As she reached the first climax of her life, she staggered and collapsed to the floor, and the way her expressionless face had unraveled was clearly visible to my eyes.
Can a woman who was so insensitive really be ruined like this just by having her erogenous zones touched a little?
No, this isn't enough. Looking at her now, my cock is at its absolute limit……. Yeah, since we’ve come this far, let’s keep pushing and break her cherry too.
"Sherri. If it's okay, here, more……."
"Spir, it……."
But that was only for a moment. Having raised her exhausted body, she turned her back on me and began to head somewhere with staggering steps.
"Spirit, it came to me."
"What? What do you mean……."
"My head, it feels clear. Right now……."
-Rustle.
A sheet of paper was spread out in front of the workbench, and the pen in her hand began to move busily.
And soon, lines of text began to appear on the paper. They looked similar to the runes engraved on the rotator still in my hand, but they were filled with content that looked much more precise and complex.
Perhaps, to use an analogy from my original world, it felt like mathematics and language were intricately intertwined……. Feeling as if I had caught a glimpse of high-dimensional knowledge, I couldn't bring myself to think about defiling her and had to ask cautiously.
"Hey, are you busy?"
"Yes. If not now, I can't do it."
She was immersed in her work, casting aside all doubts about her previous actions and all subconscious cravings.
"The next fitting is in a week. Is that okay?"
"Uh, yes. Let's do that."
"Then I’m busy, so excuse me."
I stared blankly at her as she poured her heat into work mode, and feeling the energy drain from the act that had ended in such a fizzle, I turned my back on the room.
I couldn't force myself to fuck someone working so hard……. Sigh, damn it. What should I do about my erect cock that feels like it’s about to burst?
"Huh?"
As I was reluctantly leaving the workshop, the rotator in my hand caught my eye.
Realizing only then that I had forgotten to return it, I couldn't help but wonder whether I should return this item to her or not.
Engravings are more expensive than I thought, but she herself said this item was useless……. Hmm, should I just return it next time we meet?
"Whoa~ Hey there, mister~! You’ve got something good there, don't you?"
While I was walking down the alley thinking that, someone spoke to me.
When I looked, I found a woman in a rowdy outfit approaching me with a swagger.
She was showing great interest in the rotator in my hand.

"That’s engraved, right? I don't know where you picked it up, but it looks like it would sell for quite a bit."
"……What do you want?"
"No, nothing much……. If you don't want to have a rough time, just give me some charity quietly. Huh? Isn't that simple and good?"
Geez, in this world, even pretty pussies act like thugs.
"Are you picking a fight with me?"
"Huh, so what if I am? Are you going to hit me here?"
"No, nothing much……. I just think you’re really unlucky."
Good grief, an onahole walked right into me.
My cock was already half-erect, so this worked out well.
*****
After exercising legitimate self-defense, the time for a true education followed.
"O, oh, oh, oh, oh~~~~♥♥♥"
Despite her arrogant attitude, the damn bitch who had lost her virginity so uselessly was now so intoxicated by sex that she was frantically spewing lewd moans from her lips.

"Ah, o, ohhh~ St, stop~~~♥ Don't stab me~~~♥ When you stab, it, it feels straaaange~~~♥"
"Geez, if you were going to pick someone's pocket, you should have been prepared to have your womb picked too. It worked out well since I just got my hands on a suitable toy. I’ll grind you until your pathetic, tiny tits are swollen and firm."
"N, nipples, stooop~! Don't attach weird things! My breasts, they’re, they’re tingling, o, o, st, stop, ohhh~~~♥♥"
The thug was moaning with rotators attached to both nipples while being fucked.
Feeling that the tightness I felt in the process was better than usual, a joyful smile began to form on my lips as I continued the act.
If sex can feel this fresh with just one rotator……. Oh, yeah. If I use these engravings, can I create mechanical effects like vibrations?
Then, should I earn some money and commission Sherri to make some adult toys?
