Unfamiliar Gender, Unfamiliar Lust (2)
“Kuh…!”
Han Ji-eun let out a pained groan as her throat was suddenly seized.
“You fucking bitch, shaking that ass like you want it! I’m dying here!”
She had no idea what was happening.
Her own gender had flipped completely.
And her younger sister, whose gender remained the same, now had something that definitely shouldn’t be there sprouting from her lower half.
“Ji-Ji-ah—huk!?”
A sudden impact. She realized too late that she had been slammed against the wall.
“Walking around with a body this goddamn fuckable…! Haa, haa…!”
Han Ji-ah’s breathing was ragged. Her eyes gleamed with a lust so fierce it had crossed into pure rage.
“Take responsibility!”
Heat pressed against Ji-eun’s now-softened stomach.
“Take responsibility!! I-I’m suffering, so take responsibility!”
Every shout was punctuated by a sharp jab to her belly. And with each one—
“Ugh, hek, huaah…!”
Her breaths came out shaky and far too thick to be explained by mere pressure.
Scary.
Being the target of such violent desire.
And—
Hot.
The thick rod grinding against her stomach.
It was burning. Far too hot for a human body. It felt impossible that this searing heat could come from mere body temperature.
Fear and heat alike stirred her newly female flesh.
“Ah, hnn…”
A moan that sounded like a sigh of fear, yet carried an unmistakable note of arousal.
What… is this?
While Ji-ah thrashed under the male lust she had never experienced in her life, it was now Ji-eun’s turn to drown in the female desire she had never known.
A gentle, full-body warmth unlike the urgent need to ejaculate that gathered at the tip of a cock.
Even while being cursed at and handled violently, her fingertips trembled with pleasure. Her thighs quivered. Sweat beaded under her arms, on her soles, along her back.
“Hurry up! Do something, you fucking bitch!!”
At the same time, she realized the one treating her so roughly was also being tormented by her own lust—the true tyrant—and had finally secured a female to relieve it, yet had no idea what to actually ask for.
There was a strange charm in that helplessness that tickled the female heart.
Yet Ji-eun herself was equally clueless about what to do.
Her little sister’s cock was hard and aching, so she needed to help? How?
Stroke it with her hand? Even if it was her sister’s, touching someone else’s felt… But she really did look like she was suffering, and as the older sibling—
The female didn’t know that choices had a time limit.
And once that limit ran out, the desperate male would simply take the choice away.
“I told you to hurry!!”
Ji-ah wasn’t just feeling anger anymore—she was fully aware of it.
Why aren’t you helping?
I’m in this much pain and you’re just standing there doing nothing?
With a body that slutty, you’re not even going to help me?
Fucking whore. Bitch. Goddamn cock-hungry bitch…!
“Aah!?”
Ji-eun cried out again, pain and arousal mixed in her voice.
“Get over here!”
Ji-ah grabbed her hair and the collar of her T-shirt, yanking her forward.
“J-Ji-ah—!”
“Shut up!”
Ji-eun’s body trembled, and she truly couldn’t speak anymore.
It wasn’t just obedience to an angry little sister.
It came from somewhere deeper. More primal.
She had obeyed a male’s command.
As a female.
Ji-ah dragged her across the room and threw her onto the living-room sofa.
“Aah!”
It didn’t hurt much. The real pain came from the hair and neck being yanked while she was pulled along.
Of course, whether that pain was unpleasant was another matter entirely.
“J-Ji-ah.”
Ji-eun spoke even as she trembled.
She had obeyed the male’s order on instinct just now.
But humans had reason. And because they had it—
“L-Let’s not do this, okay?”
She rebelled. Against the instinct that told her the wrong answer.
“I-I’m really Han Ji-eun. Your older brother, Han Ji-eun…!”
She tried to cling to scraps of morality and common sense. Rationally.
“I-I’ll help you, okay? I’ll tell you how to… deal with it…!”
Ji-eun’s voice rose higher because Ji-ah had silently climbed onto the sofa with a terrifyingly blank expression. The younger girl pointed at the massive bulge threatening to tear through her dolphin shorts and gave a single command.
“Suck it.”
An order a little sister should never give her older brother.
“T-To your big brother—”
Slap!!!
This time it was an action a little sister should never do to her older brother.
She had struck her cheek. Hard enough to turn Ji-eun’s head to the side.
“…Ah.”
Ji-eun touched her own cheek in a daze. It throbbed.
I… just got slapped by Ji-ah?
The moment the realization hit, heat flooded from her stomach down between her legs.
“Whether you’re Han Ji-eun or whatever, I don’t give a shit.”
Ji-ah already believed the female in front of her was indeed Han Ji-eun. She simply didn’t care about that fact in the slightest.
“Suck it, you filthy slut.”
Of course, the newly female Ji-eun had no sexual experience.
But if her cock was suffering because of this bitch, then she was a slut. Virgin or not.
“Suck it already!!”
And if a slut who had angered a male refused to listen, then she had to be punished until she obeyed.
Smack!!!
Another, harder slap. The red mark on her cheek darkened.
“Ah…”
Heat surged up from Ji-eun’s stomach, pulsing through her entire body in time with her heartbeat.
“I-I’m sorry.”
She apologized. Not just to avoid violence, but because she truly felt sorry.
An irrational guilt between older brother and younger sister.
Yet between male and female, it was the most natural remorse in the world.
Ji-eun reached out with a trembling hand—pale and delicate, unlike when she had been male.
She was shaking. From fear.
But not only from fear.
“Haa… haa…”
Listening to Ji-ah’s ragged breaths, Ji-eun grabbed the hem of the dolphin shorts and pulled them down.
The massive cock caught on the fabric, making it difficult, but at last it sprang free.
“Kyaa!”
The thick shaft slapped Ji-eun across the nose from below.
A dizzying pain. Tears welled up.
But she had no time to dwell on it.
“Wow…”
It was huge.
Hot.
And thick.
What… is this?
Especially with it right in front of her face, the impact was overwhelming.
Long enough that even two hands couldn’t cover it to the tip. Thick enough that one hand couldn’t wrap around it.
Bulging veins ran along its surface, and clear fluid dripped steadily from the plump, almost menacing glans.
“Hiss, hnn, haa…”
Inhale. Exhale.
The scent of cock filled her lungs.
“Haa, hnn.”
She leaned closer, toward the stronger smell.
“Huuu… haaa…”
It smelled like a girl, yet unmistakably male. Softer and sweeter than the scent her own body used to give off, but undeniably male.
“Haa, hnn… hiss, haa…”
Her eyes grew hazy.
Her mind spun.
Her body, already prepared to submit to a male, inhaled the scent, registered it, and engraved it onto her arousal switch.
But the male in front of her right now was in no state to consider a female’s circumstances.
“Aah, seriously!!”
Ji-ah grabbed the sides of Ji-eun’s slack, dazed face with both hands.
“If your teeth touch it, I’ll kill you!?”
“Ubgk!?”
She thrust straight between the soft lips.
“Ugh!? Kuhk, ooeek…!! Kgghk!!”
If it had been gentle sucking, only wet sounds would have followed. But this was throat-fucking with no mercy, and the noises were far from seductive.
Desperate attempts to breathe. Air scraping through the narrow gap around the blocked throat. Irregular wet sounds as air bubbles formed and popped inside the convulsing passage.
All of it mixed into—
“Kuhk, ugh, spurt, ka, kghk…!!”
A rather ugly sound.
The wet, choking cries of a female throat-pussy.
Yet no one present found the sound unpleasant.
The owner of the cock that had claimed the throat first—
What… the hell… is this…!
She was experiencing the pleasure of a cock for the first time. Her vision whited out; the glans and every inch down to the base were wrapped in scorching heat.
She was already struggling just to endure the sensation.
And the owner of the throat forced to swallow it—
Kuh! It’s too big…!
Was equally desperate to endure.
The enormous shaft blocked even her airway. The taste on her tongue and in her nose. The feeling of being used so forcefully—
“Kahk, kghk, haaah…♡”
Masochistic pleasure.
Female lust.
Just as Ji-ah had been confused and overwhelmed by the male urge to release she had never known, Ji-eun was now confused and overwhelmed by the female lust that melted both body and mind into sticky sweetness.
Female desire had no clear outlet. No post-nut clarity from ejaculation, and no guarantee that climax would cool the heat.
Unlike males who charged straight toward release, females found far deeper, richer mental pleasure in the entire process of sex itself—the shared act, the sensation of bodies pressing and mixing together.
Good…♡
And for Ji-eun, who had only just become female, it was an utterly alien feeling.
Pride.
Fulfillment.
Satisfaction.
Until now, she had only tasted such feelings when praised for her studies, and even that had starved for a long time after she became a shut-in.
Now those feelings flooded her all at once. A profound mental satisfaction. One of the most intense desires a person could have.
Moreover, because she had been male until moments ago, her brain had no defenses against this overwhelming mental pleasure.
Happy…♡
She became happy with embarrassing ease.
Even while her little sister’s cock was rammed down her throat, cutting off her air—rather, precisely because of that.
Her mind floated. Her body went limp. Tears from her gag reflex welled up, and her eyes naturally curved into a smile.
And then—
“Haa, haa… good, feels good…”
Ji-ah, finally somewhat accustomed to the pleasure, gripped both sides of Ji-eun’s mouth-pussy even tighter.
“Good, ah, ah shit…!”
“Kuh!? Heuk, hnn—khk, ugh!”
She began to thrust.
“Ah, ah shit!! Good!! Good!! So fucking good, you goddamn crazy bitch!”
No—she began to use her. Thrust! Thrust! Thrust! Thrust! With no consideration whatsoever for the hole she was pounding.
Treating it exactly like an onahole.
