Teaching My Snobby Hikikomori Childhood Friend a Lesson With the Mating Press
"Alright then, let's measure it again~"
"…Do whatever you want."
How on earth had it come to this?
Right now, I was comparing which was longer—my 25cm plastic ruler, or her cock.
The rule was simple: if she couldn't beat the ruler even fully hard, she wouldn't get to stick it inside her pussy. A game that sent chills down my spine and, at the same time, cranked my excitement up to another level.
She's the one who asked me to insult her cock in the first place, but I never expected her to slander it this enthusiastically.
'So she really did have a lot pent up against me, huh?'
I'm a college dropout bum now, but believe it or not, I used to be called a child prodigy.
Back in elementary school, Narae and Dallae—the same age as me—couldn't keep up with my grades no matter how hard they tried, and they crashed and burned constantly.
From what I hear, they got compared to me by their parents every single day. Yuseon studies so well, why can't you put in more effort? Something like that.
After that, she apparently spent all her energy jerking off and never really distinguished herself again, but maybe somewhere along the way her desire to beat me just quietly grew and grew.
'Well, she looks like she's having fun, so I'll just let her be.'
Dallae gets to fill up on psychological superiority by teasing me however she likes, and I get to relieve my lust. Win-win.
In that case, there's no reason to fight it. The smart move is to lie back and savor the situation.
"Hmm. Maybe it's because you're not fully hard yet, but I don't think you can beat 25cm~"
The one spitting out those words while fondling my cock this way and that—
I'd already cum three times having sex with Areum yesterday, so my cock was in no condition to be at full power. Even after the morning blowjob Dallae had given me, it was still hanging soft and loose.
At the moment it was only semi-hard, reaching about 20cm. There was no guarantee it would even hit 25 at full mast.
'Last time I measured, it was around 23. Whether it grew another 2cm since then… who knows.'
Whether or not she knew about my inner anguish, Dallae pressed the plastic ruler against my cock over and over again, continuing the comparison—
"Hmm~ So you can't even beat a single plastic ruler, Yuseon? What a pathetic little cock."
"……"
I figured almost no man on earth has a cock over 25cm, but even being unreasonably insulted like this turned me on.
It's not every day you get to measure a genuinely huge cock against something even bigger, feel your defeat sink in, and savor the loss.
"Haah, haah…"
And so I—a masochist for massive cocks—was experiencing an excitement I'd never known, getting my own cock insulted right to my face.
How long had I been content fooling myself with doujin ASMR of all things? I'd dreamed a hundred times over of a cute girl looking me in the eye and shredding my big dick.
'And her body is so fucking hot, too.'
Thanks to that, my cock was finally starting to respond. It had been so limp just moments ago, but before I knew it, it had swollen to its usual fully-erect proportions.
"Getting hard while your cock gets insulted? You're a huge pervert~ Though you're still nowhere near 25cm~"
Watching me, she grew even more smug and started digging the knife in deeper.
Sure enough, my cock was still stalled around the 21cm mark. Any normal person would think it impossible for it to stretch all the way to 25cm from here.
Losing soundly to a mere measuring tool wouldn't be the worst outcome, but if I could help it, I wanted to push past my limits and seize victory.
"Hmm, what to do~ If you can't beat this, should I call you baby-dick for the rest of your life~?"
"……"
One thought burned in my mind: I wanted to fuck the bratty bitch taunting me with her cock-shaming, and stuff her to the brim with my cum—
Above all, I wanted to see that always-insolent childhood friend of mine getting her pussy speared, wailing like a bitch in heat.
My cock responded to that desire, surging back to life until it sprang up like a loaded spring and blew straight past the ruler.
"……"
My overwhelming cock casually towering over the long 25cm plastic ruler.
And it didn't stop there. It kept growing until it reached Dallae's face, bumping against her philtrum with a soft thud.
"Hyagh!"
She let out a short scream at the blunt impact and clutched her own face with both hands.
But that settled it. I'd gotten plenty of pleasure out of having my cock insulted, and all that remained was to feast on my childhood friend's pussy.
"I won. Time to use that pussy."
"…Hehe. It's way bigger than I expected, sure, but you won't break me that easily? My body's not the type that feels much, you know."
I had to give her credit for taunting me right up to the very end, fighting for every scrap of superiority. She looked like an ordinary hikikomori, but was she actually a total sadist?
I immediately fished a condom out of the cardboard box and rolled it down over my rock-hard cock.

"Can your pathetic little cock actually get me going, Yuseon~?"
A short while later—

"Nghoooooht♡ Ahhk, stop, stop hitting me all the way insideeeeahhh♡"
"……"
Dallae, pinned beneath me and taking the mating press, screamed out her pleasure like a beast in heat.
I looked down at the sight with a mixture of disbelief and amusement.
Just minutes ago she'd been boasting—my body doesn't feel much, you know, can your pathetic little cock even get me going~?—and now a single round of thrusting had left her unable to move a muscle.
With all that trash talk, I figured she'd hold out longer than any of the other girls, but she turned out to be the most sensitive of the four. Her pussy kept gushing love juices nonstop until my entire bed was soaked through.
"…Should I go a little gentler?"
"Gentle, please go gentleeeth… I'm gonna die like this…"
Could my cock actually kill a person? That thought was starting to scare me a little.
'Her pussy feels great, but her moaning is so loud I can't concentrate.'
Her shameless wailing kept making my hips buckle reflexively. Her moans were honestly kind of dirty, too.
'Maybe it's because I jumped straight into a mating press without warming her up first. Her pussy just hasn't adapted to my cock yet.'
A variation of missionary that lets the cock sink in at its deepest possible angle—the so-called mating press.
Also called a bent position, it involves the woman hooking her legs up over the man's back or shoulders so that their hips press flush together.
Thanks to that, my huge cock was churning up her insides to the point where it could casually knock on the entrance of her womb.
"What a garbage-tier pussy. And here I actually expected something from all that bravado."
Left with no choice, I slowed my pistoning to about half speed, giving her pussy time to adapt to my cock.
Slap— slap—
"Ah, ngh… hnnnn…"
Whether it still hurt or she was just putting on airs, she gripped my back with both hands and desperately fought to hold in her moans.
"You can handle this pace, right? Even if you can't, tough. Deal with it."
"Yuseonaaah, g-gently, just a little more gently…"
"Nope."
I'd already cut my speed in half. Any slower than this and I probably wouldn't be able to cum even after thirty minutes.
I kept pistoning away regardless, and sure enough, she started spewing out filthy moans one after another, doing nothing but proving that her pussy really was trash after all.
I'm a masochist who gets off on having my cock insulted, but I also enjoy the kind of content where a bratty brat gets put in her place. There's just something charming about watching her taste a real cock and slowly admit defeat.
Which is why even this sight—Dallae, who'd mocked my cock so relentlessly, now sprawled beneath me and losing her mind—was turning me on just fine.
"I-I lost, okay…?! I'll apologize for calling it a pathetic cock, so pleeease…! Hngh, please go gentle…!"
"Oh?"
When she begged this earnestly, I honestly wouldn't have minded slowing down for real.
But the moment I saw Dallae's face—tearing up, wearing that utterly defeated bitch expression—any such urge evaporated.
"Aaah, you're not going gentle at all, you're going even fasteeeer— mmph—?!"
I grabbed her cheek and, without warning, crushed my mouth against hers.
Partly to shut up those noisy moans, but honestly—and this pains me—her face was just so damn cute that I couldn't help myself.
"I'm about to cum. Fast is fine now, right?"
"N-no waaay…! If you go any faster than this…"
I was planning to pound her fast no matter what she said, so I immediately picked up the pace, driving my lower body up and down with full force.
Between having my cock insulted and witnessing the bitch-in-heat side of my insolent childhood friend, my climax came roaring up at once. I plunged my cock deep one final time and erupted, blasting my cum hard against the entrance of her womb.
Jiggle— jiggle—
"Nghooooooh—♡"
Even through the condom, I could feel my release churning wildly inside Dallae's belly—a load of that magnitude.
Her moaning grated on my nerves, sure, but her pussy was still absolutely top-tier. Snug in just the right way, and taking my cock perfectly.
"Whew. That was a massive load. So? Ready to admit your pussy's trash?"
"……"
She lay there in silence, the cum-filled condom still buried in her leaking pussy.
Apparently she'd passed out. Or maybe she was simply so spent she didn't have the energy to answer.
Slap!
"Nyagh?!"
One firm two-handed squeeze of those enormous tits and she snapped right back to her senses.
