I savored the fullness of penetration, still restraining my vigorous movements.
I pushed in very slowly, just a little at a time, centimeter by centimeter.
After thrusting all the way to her cervix, I slowly pulled my cock out.
“Hoo….”
Nari’s pussy felt so good that I involuntarily let out a satisfied sigh.
Each time my cock made the slightest back-and-forth movement inside Nari’s pussy, the little bumps along the inner vaginal walls gently scraped my glans.
Naturally, the sensation was pure pleasure, not pain.
Perhaps because Nari’s tongue was so impressive, the bumps sometimes felt like tiny tongues.
This pussy… was fucking insane.
It was a completely different structure from the pussies I’d known until now.
Did all women have differently structured pussies?
It was as though Nari’s entire pussy were one enormous living fleshlight designed to milk semen.
-Schlup schlup
The inside was hot, soft, and reacted to every movement like a living creature.
If Iseol noona’s honed pussy gave me the pleasure of a practiced technique that squeezed my cock, Nari’s pussy offered the pleasure of natural talent, just like her fellatio.
But Nari’s reaction came much faster than I expected.
“Hnngh, ah, ah! This is strange…! My pussy, my pussy is moving on its own…! It feels so good…!”
I had only moved back and forth a few times. I hadn’t even deliberately touched anywhere like the G-spot.
Even so, the walls of her vagina were already twitching in tiny spasms, showing signs of an impending climax.
Those faint tremors in her pussy were transmitted vividly through my cock.
At that moment, Nari’s pussy was moving greedily, as though it wanted to swallow my cock rather than merely accept it.
Her orgasm was building so quickly that Nari cried out, lewd moans spilling from her lips.
“I’ve never… hng… learned anything like this…! Mom never taught me this kind of pleasure…! Hyaaang!”
“Really?”
-Squeeze
Listening to Nari’s ragged breathing, I grabbed her large breasts, swaying before my eyes, with both hands.
Their heavy, yielding flesh filled my palms. Her skin, slick with sweat, clung to them.
I kneaded the soft flesh like dough while moving my hips a little deeper.
The sensation of a woman’s breasts freely changing shape in my grasp gave me an immense sense of conquest.
“Your breasts are fucking sexy.”
“Hng, hyaa… Please touch my worthless breasts a lot….”
It felt unbelievably good. If I kept thrusting like this, I felt I’d cum within ten minutes.
Sex really was the best. Forget surveillance or whatever—the best feeling was irresponsibly dumping my semen into a woman’s pussy.
It was fun, too, watching the face of a woman so overwhelmed by the pleasure my cock gave her that she didn’t know what to do.
Just then, Nari’s legs tensed hard. I could see the muscles in her white thighs drawing taut.
“I’m c-coming…!”
Nari suddenly climaxed first.
Her pussy clamped down hard on my cock as though convulsing. The contractions were incredible.
It felt as though all the ridges and bumps inside were licking my cock.
For an orgasm that had come so quickly, the vaginal pressure was incredible.
Nari gripped the white bedsheet so tightly that her fingernails turned white, her back arched deeply as she trembled.
This wasn’t an act; it was a real orgasm, a genuine climax.
Her climax came much sooner than expected, which flustered me slightly, but I didn’t bother to stop. If anything, the sight of it only stoked my arousal.
“You’re coming already when we haven’t even really started? What a pathetic pussy.”
I whispered into her pleasure-dazed ear and moved my hips even harder.
-Thud, thud, thud!
The sound of flesh slapping against flesh rang out much wetter and lewder than before.
Nari’s juices, released with her climax, served as lubricant. My cock ravaged the deepest parts of her without restraint.
“Haa, ah! Mr. Sihyeok, wait, just wait…! It’s too fast…! Hngh, I just came, I just came…!”
The pleasure was far stronger than she’d expected, and the successive orgasms made Nari show signs of wanting to stop.
But Nari couldn’t bring herself to ask me to stop.
Her eyes held both a desire not to miss this golden opportunity to have sex with a man and a female instinct not to disappoint me.
The expression on her face as she pleaded with tears welling in her eyes was incredibly arousing.
“All right, all right. Since our Nari has such a pathetic pussy that she climaxes so quickly, I’ll thrust slowly.”
“Th-thank you… hng!”
I stopped my rough movements out of consideration for Nari and began moving very slowly again.
As the tempo slowed, a different kind of pleasure enveloped us.
I could feel each of the bumpy folds inside Nari’s pussy in detail, while Nari seemed to savor the full thickness and shape of my cock.
The room had grown a little quieter, so I deliberately tossed out a lewd remark.
“Didn’t you practice your sexual endurance? Did you think being good at fellatio was all it took?”
Nari answered my teasing question between ragged breaths.
“Mom said ordinary men finish within three minutes… And she never told me a cock could be this big….”
Her words made me think of the average size and premature-ejaculation tendencies of men here.
My cock was an off-spec item in this world.
Then again, even a man from my original world would blow like a premature ejaculator after being used to a loose pussy and then taking on a state-of-the-art fleshlight.
I could understand Nari’s quick climax a little better.
“Then my cock being so thick must make this difficult, right? What if this pussy gets stretched out because of my cock?”
When I asked, Nari immediately shook her head as though she’d been waiting for me to ask.
“No! It’s not difficult at all! Thrust deeper, deeper. Fill my pussy full with your cock, Mr. Sihyeok! Please, keep thrusting…!”
Her voice was desperate. I grinned and decided to grant her wish.
This time, I slightly twisted the angle of my hips to target her cervix directly.
But the thought of immediately thrusting just because she asked made me feel a little unsatisfied.
“You don’t get it that easily. This time, you move yourself. Prove to me how filthy your pussy is.”
“Huh? I only know the cowgirl position….”
“I’m not telling you to ride me. Just sway your hips a little and use your pussy to make my cock feel good.”
Nari’s face reddened with embarrassment and arousal at my command.
With my cock still inside her, Nari began twisting her hips clumsily from side to side.
When my expression didn’t change, she tightened her pussy a little more and gave her pelvis a slight up-and-down shake.
Each time Nari moved, the bumps inside brushed over my cock like a tickle.
“Hngh… like this…? Is this right…?”
“That’s it. More lewdly. As though your pussy is desperate to have sex.”
With my encouragement and coaching, Nari’s movements grew increasingly bold.
She began rotating her hips in circles.
The vaginal walls pressed against and rubbed my cock from every angle.
Watching her move to seek pleasure for herself gave me a different kind of pleasure from when I had been doing all the thrusting.
Before long, Nari’s movements began to grow more intense.
Another climax was approaching, born of the pleasure she had created herself.
This time, I had no intention of letting her reach climax merely by moving on her own.
I slightly twisted the angle of my hips to target her cervix directly, then thrust upward hard from below.
-Wham!
“Hyaaang…!”
A deep, powerful stimulation, incomparable to the pleasure of swaying her hips herself, pierced through her body.
“Ah! Ah! There, there…! I need the bathroom…!”
Startled by the unfamiliar sensation of needing to urinate, Nari screamed.
Her lower abdomen began twitching and spasming. I kept striking that spot relentlessly.
“It’s coming, it feels like it’s coming…! Something strange, it’s coming out…!”
Not long after, Nari reached her second climax, and when I pulled my cock out, she gave a spectacular squirt.
-Pshhtshht!
Clear orgasmic fluid traced an arc, soaking my lower abdomen and the bedsheets.
Along with the sensation of hot liquid touching my skin, a lewd scent spread through the room.
“Ohhh, it’s coming, it came out…!”
For a moment, a female animal’s cry burst from Nari’s mouth, unlike her earlier sounds.
For an instant, her eyelids nearly rolled back.
“Hii, hiit…!”
Embarrassed at having squirted like a fountain, Nari lightly covered her face with one hand.

Her face covered like that was cute, so I hugged her tightly as though she were adorable.
Nari instinctively wrapped her arms around my neck and clung to me.
Soaked in each other’s sweat and scent, we resumed our fierce coupling.
Nari wrapped her legs tightly around my waist, while I whispered by her ear and thrust deep into her womb.
“You’re so overwhelmed because you like my cock, huh? You’re a really filthy bitch, aren’t you?”
“Y-yes, yes! I’m a filthy bitch…!”
As her body trembled through her third climax, I could no longer hold back either.
I’d lost count of how many times I’d rubbed my glans against those bumpy ridges.
My cock, having reached its limit, began streaming precum.
I thrust my cock all the way to her cervix and poured everything out.
-Brrrrt! Brrrrrt!
The sensation of my semen filling the deepest part of her pussy.
The mental thrill of an act that might create a baby, combined with the pleasure surging from my cock, made the tension in the back of my neck release all at once.
“Hew, uhh, haa, haaang…!”
With her sweat-soaked hair stuck to her cheeks, Nari met my eyes with an exhausted expression and giggled.
“Mr. Sihyeok’s semen… it went inside my pussy….”
After ejaculating, when Nari let go of me, I straightened my back while lightly pinching her nipples.
When I pulled my cock out, red blood from her virginity mixed with my white semen and steadily leaked from her pussy.
“Nngh….”
Nari’s thighs trembled and spasmed. This was erotic too.
I looked at Nari, whose stamina for sex was already spent.
I wanted to keep going, but would it even be possible?
For now, I hooked one of Nari’s legs beneath my crotch and draped the other over my shoulder.
Nari naturally turned onto her side, facing the side of the bed.
“Ah, eh?”
Then I inserted my cock into her thoroughly soaked pussy again.
