How to Enjoy a Common Sense-Altering World

Chapter 7: Measurement 

I approached the gyaru duo with the dildo reinserted. 

We proceeded with the registration at the reception desk. 

"Name is Kim Jinwoo, age 25. No allergies or other issues." 

"My only strong point is my body." 

I may not be good at much else, but at least I'm healthy. 

I've never even had a cold since childhood. 

I've lived a peaceful life without any major incidents. 

The white gyaru added a cheeky comment to my mundane self-introduction. 

"Oppa seems to have a lot of hidden talents." 

"You think so?" 

"Yes, like your thick, juicy cock for example?" 

The white gyaru gave me a seductive wink. 

It felt like I was being seduced by a fox. 

No wonder they call women like this foxy. 

If this isn't flirting, I don't know what is. 

While we were bantering, the white gyaru finished the registration and continued guiding me. 

"Registration is complete. When your number appears on the screen, please proceed to the examination room." 

"Thanks. It wasn't as complicated as I expected." 

"No problem. Oh, and take this too." 

She handed me a small piece of paper, telling me not to forget it. 

On it was written "Baek Yujin" along with a phone number. 

"Baek Yujin. That's my name. Call me if you ever need a pussy." 

"Sure, see you next time, Yujin." 

"Hehe. See you later, oppa." 

I immediately took out my phone and opened my contacts. 

There was an empty slot after family and close friends. 

I felt satisfied just adding Baek Yujin's number there. 

Just then, the black gyaru who had been silent until now spoke up angrily. 

"No fair! Yujin, are you trying to monopolize oppa all to yourself? That's not right!" 

As if competing, she quickly scribbled down her own name and number. 

"I'm Yoo Sehee. I'll come running anytime you call." 

"Anytime?" 

"Mm, I'll come even if you call at dawn. So make sure to call me, okay?" 

I couldn't help but smile at Sehee's cute, whiny voice. 

If Baek Yujin was a seductive fox, Yoo Sehee was like an overly excited puppy. 

They were truly like oil and water. 

Though they seemed incompatible, I could see they were actually quite close. 

Perhaps it's because they both like dick? 

'No, don't all women like it?' 

Maybe I just haven't seen it before. 

Or maybe I'm just oblivious. 

At least I've never seen a woman who hated dick until now. 

As if to prove that point, every woman who passed by kept glancing at my crotch. 

"By the way, who's that unni you're with, oppa? I'm confident in my breasts, but I can't compete with hers at all." 

Sehee caressed her own breasts, showing off their size. 

Certainly, Sehee's breasts were large. 

But compared to Jung Sahwa's breasts, they were barely a handful. 

Her breasts were as big as Sehee's entire body in that micro bikini. 

Just then, Jung Sahwa cleared her throat and introduced herself from between her breasts. 

"Excuse my late introduction. I am Jung Sahwa." 

"Whoa, an executive? My, what an impressive unni you are... oh..." 

The moment Sehee received the business card, her face turned pale. 

As if she had seen something she shouldn't have, her legs trembled. 

Then she wet herself on the spot like a frightened puppy. 

"I-I'm so sorry! I spoke carelessly without knowing! I'll be more careful from now on! Please forgive me!" 

In that moment, Sehee bowed deeply over her own puddle without a trace of her usual playfulness. 

I was surprised by her suddenly formal speech, 

but I was more shocked by Jung Sahwa receiving such treatment. 

I had seen my family treat her like royalty, but this was on another level. 

Seeing her cause such a reaction, I realized once again. 

Jung Sahwa was not just some executive of a strange organization. 

"It's alright. Please raise your head." 

"R-really?" 

Jung Sahwa reached out to the trembling Sehee. 

She gently comforted Sehee, saying it was okay. 

"I didn't come here looking for you specifically." 

"I-is that so? I'm sorry for jumping to conclusions." 

"I simply accompanied Mr. Kim Jinwoo as his assistant." 

"Eh!?" 

Sehee looked at me with surprised eyes. 

It wasn't a lie, but... 

Given what she had just witnessed, my position must have seemed strange. 

"O-oppa, are you someone important?" 

"No, I'm just an ordinary civilian." 

"...Really?" 

She was clearly suspicious. 

Well, even the president had used honorifics with me. 

Would she believe me if I claimed to be an ordinary person? 

I patted Sehee's butt and sent her to the bathroom. 

"More importantly, go clean yourself up." 

"Ah, um. Thanks, oppa. See you later then." 

I watched Sehee leave with a shy wave, then headed to the examination room. 

*** 

The health examination ended normally. 

Perhaps thanks to Jung Sahwa's preparations. 

They thoroughly examined me from head to toe. 

As a result, it was revealed that there was nothing wrong with my body. 

"You're quite healthy. Especially for someone who was a hikikomori for over a year." 

"Where did you get that information?" 

"Don't underestimate our intelligence network. If you want, we could even find out the Italian president's underwear size." 

I don't want to know that. 

The current Italian president is a man anyway. 

I'm more curious about the nurse's nipple color than some guy's underwear situation. 

"So all that's left is the grade measurement?" 

"Yes, once the measurement is done, today's examination will be over. It's been tough, hasn't it?" 

"Well..." 

I tried to answer calmly, but it really had been difficult. 

Nurses exposing their bodies in the hallway, 

and fondling me under the guise of an examination more than once or twice. 

Some nurses even masturbated using my legs. 

That's when I truly felt I was in a common sense-altered world. 

As I stretched in my chair, 

Jung Sahwa took out a tablet from between her breasts. 

"So who would you like as your grade measurement assistant?" 

"I choose from this list?" 

The tablet screen was filled with nurses' faces. 

Seeing someone's eyes turn black, it felt like choosing a partner at a brothel. 

I wanted to ask for a pretty nurse if possible. 

But it's hard to choose like this. 

Should I just pick randomly? 

I let out a sigh, unable to decide on a nurse I liked. 

Then suddenly, the faces of the gyaru duo popped into my mind. 

"Ms. Jung Sahwa. Is the grade measurement only possible with nurses?" 

"No. As long as they can help you ejaculate, any woman is fine." 

"Oh, in that case...!" 

I immediately took out my phone and made a call. 

As promised, it didn't ring for long before I heard a bright voice on the other end. 

-Hello, oppa. What's up? 

"Ah, Sehee. It's nothing big. I just need a grade measurement assistant." 

-Ah, you mean you need help? Then I'll come with Yujin! 

I didn't ask for Baek Yujin too, but there's no reason to refuse if she's coming along. 

After waiting a bit, Baek Yujin and Yoo Sehee came running. 

"Oppa, did you wait long?" 

"To think we'd meet again so soon. You must have really missed us." 

"Well then, I'll leave it to you both." 

I approached the two and grabbed their shoulders. 

Usually this would earn me a slap, but both girls just blushed happily. 

"Geez, oppa is so impatient. My body's already heating up because of you." 

"Oppa, you made our bodies like this, so you'll take responsibility right?" 

"Of course." 

I confidently answered their expectations. 

*** 

The space for penis grade measurement. 

It sounded grand, but in reality it was just a small room with a bed and condom dispenser. 

Instead, the floor and walls had a smooth coating. 

This must be a place for doing naughty things, specially prepared. 

'When will they come?' 

The two said they needed to prepare and sent me ahead, but they're still not here. 

It's embarrassing enough to keep waiting like this. 

My dick is throbbing painfully, eager for women. 

Just then, as if answering my prayers, the door opened and the gyaru duo entered. 

"How is it, oppa? Do I look cute?" 

"Wow..." 

I couldn't help but let out a gasp. 

They were cute when I met them earlier too, but their current outfits were on another level entirely. 

Yoo Sehee wore a micro bikini that barely covered her nipples. 

Baek Yujin wore a see-through string bikini. 

Moreover, both of their arm bands, knee socks, and swimming caps were all made of latex. 

It was an outfit prepared specifically for receiving semen. 

"It's my first time wearing a grade measurement outfit, but I like it since oppa seems to like it." 

"Well then, since oppa waited so long, let's get started right away." 

Yoo Sehee took a condom from the dispenser and put it in her mouth. 

Then she knelt in front of me. 

She carefully put the condom on my penis with her mouth. 

But maybe because the condom itself was small, 

it didn't reach all the way to the base. 

"The condoms provided here have their limits." 

"Can't be helped. Oppa's dick is just that big." 

"Hehe, right?" 

Saying the preparations were done, the two massaged their arm bands. 

They said we'd start gently at first, 

as the two began stroking my dick from both sides. 

They didn't just move up and down monotonously. 

Sometimes they'd tap the glans with their fingertips, 

or gently caress the shaft. 

They skillfully stimulated me, drawing out my ejaculation. 

'This is hard to endure.' 

As they stimulated me in different ways, 

it felt so good my brain was tingling. 

My body urged me to cum quickly, but I couldn't ejaculate like a premature ejaculator in front of these two. 

I slowly steadied my breathing, 

and recited multiplication tables in my head. 

But they seemed to realize I was holding back. 

The two launched an additional attack. 

"Oppa, it's not good for your body to hold back." 

"Stick out your tongue. We'll make you feel good." 

I stuck out my tongue and it intertwined with theirs. 

Unlike a deep kiss to share intense passion, 

this was a sloppy kiss solely to receive saliva. 

The two eagerly licked and sucked my tongue. 

They generously shared their saliva just for me. 

At that moment my head went blank, 

and the ejaculation I had been holding back burst forth uncontrollably. 

Spurt! Spurrt! Spurrrt! 

"Amazing! I can tell the condom is about to burst." 

"Here, oppa. It's thick semen that you can feel the weight of." 

Their expressions might be exaggerated, but I really did ejaculate intensely. 

If there hadn't been a condom, it probably would have flown 2 meters. 

The heavy condom dangled from the tip of my dick. 

Due to the semen inside, it hung down like a water balloon. 

I carefully removed the condom, and tied it off for complete sealing. 

As I was about to put it down, 

"Wow. Yujin, look at this. It's 300g." 

"No wonder my womb felt heavy yesterday. It was because of oppa." 

We had creampied twice each yesterday. 

That means 600mL of semen was injected into each of their wombs. 

It's no wonder they felt heavy with that much. 

"Then oppa, where should we put this?" 

"Can't we just set it down somewhere?" 

"Aw oppa. You think we're dressed like this for no reason?" 

We weren't? 

I thought they just wore it because they were horny. 

"This is how you hang the condom." 

"Ooh, that's nice." 

Yoo Sehee demonstrated by bringing the condom to her swimsuit. 

Hearing the explanation suddenly piqued my interest. 

It would be fine to hang it on the swimsuit like Yoo Sehee showed, but... 

I hung the condom somewhere other than the swimsuit. 

"Ungh!" 

"I'm jealous. Oppa, can you do it to me next?" 

I tied the condom to Baek Yujin's right nipple. 

Yoo Sehee looked envious. 

She urged that it should be her turn next. 

I told her not to rush, pinching Yoo Sehee's nipple as I spoke. 

"You're next, so just wait a bit." 

"Hehe. Thanks, oppa. Oh, that's right..." 

Just then, an ominous voice came from Yoo Sehee's mouth. 

Did I make a mistake somewhere? 

Anxiously, I looked at Yoo Sehee. 

She took out a measuring tape with an awkward smile. 

"Sorry. We should have measured the size first." 

"Usually it shrinks a bit after ejaculating once." 

Baek Yujin also realized the mistake, 

and sighed at her own blunder, furrowing her brow. 

But you know what? 

I ejaculated over 10 times but still haven't gone soft. 

Of course, it won't shrink after just one ejaculation, and remains just as erect as before. 

"It's fine. See how hard it still is? It hasn't shrunk at all." 

"Certainly." 

"As expected of this dick." 

They brought their hands to my penis with sighs of relief. 

To prevent it from going soft, 

they quickly took out the measuring tape and measured the size. 

"Length 26.2cm. Thickness 6cm. Circumference 16cm. Just based on size alone, it's B+ grade." 

"Isn't it A grade?" 

"It's fine. With such thick semen, it's definitely A grade." 

It's a compliment that my dick is so big it's at least B+ grade. 

If we include my semen too, 

it would easily be A grade with room to spare. 

"Then let's hurry and go again!" 

"Oppa, do your best." 

Determined to get an A grade, they put on a second condom. 

The gyaru duo tried to skillfully coax out my ejaculation. 

But this time, instead of a sloppy kiss, 

they both greedily attacked my nipples, sucking lewdly. 

"Slurp, slurp. Oppa's nipples taste better than I thought. Slurp." 

"Slurp. How is it, feels good right? Slurp." 

"Ungh!" 

Men don't usually get sucked by women, but nipples are definitely an erogenous zone. 

Of course it feels good to have them touched or sucked normally. 

But how could it not feel amazing to have beauties sucking my nipples? 

Flicking their tongues all over, or latching on like leeches to suck hard. 

They each ravaged my nipples as they pleased. 

Every time, it sent shivers down my spine like electricity. 

Seeing through that, the two moved even more intensely. 

"Oppa, don't hold back, just let it out. Slurp." 

"Suck, pop! If you cum now it'll definitely feel good. Slurp." 

"Ungh!" 

Honestly, I'm at my limit now. 

But it would hurt my pride to cum alone, so I grabbed both of their breasts. 

"Woah!" 

"Suddenly touching..." 

"Let's cum together. Or do you not want to?" 

At my question, as if they didn't dislike it, 

they latched on tightly and sucked my nipples. 

When I roughly groped their breasts in response, their bodies trembled slightly. 

The faster their tongues moved, the rougher my hands became. 

Like a game of chicken, 

we raced towards climax like racehorses. 

"I'm cumming, both of you!" 

"Ohhh!" 

"Ungh! I'm cumming!" 

Spurt! Spurt! Spurrrt! 

Splurt! Splurt! Sploosh! Splurt! Splurt! Sploosh! 

The gyaru duo sprayed intense streams of fluid in sync with my ejaculation. This time seemed better than before, as the amount of semen visibly increased. 

"Usually it decreases after the first ejaculation." 

"It increased instead." 

"That's proof of how hard you both worked." 

Honestly, it doesn't come out that much when I masturbate alone. Maybe half of the first ejaculation? That's about normal when doing it solo. Realizing they were the cause of the increased semen, the gyaru duo blushed and looked at each other. 

"Yujin, I don't think I can take anymore." 

"Me neither, Sehee." 

"Huh?" 

The two suddenly stood up, leaned against the wall and stuck out their behinds. Then they pulled their swimsuits aside to expose their pussies. 

"Oppa, hands weren't enough, right? Let's measure with our pussies now." 

"Pound our pussies with your magnificent, extreme cock." 

"..." 

As if entranced, I put on a condom and approached them. It seems the real measurement is about to begin.
