Not Just the Younger Sister, But the Older Sister Too (1)
Ji-yeon, Ji-eun’s older sister, was having the worst day she could have ever imagined.
She woke up to find a penis growing between her legs. It was the kind of absurd nonsense that only happened in low-budget American B-movies.
The problem was that it had actually happened to her. It was real.
“Nngh… ah…”
Still, she somehow managed to drag herself to work—not because her willpower was stronger than Ji-ah’s, but because skipping work carried far heavier consequences than skipping school.
The moment she arrived, however, she had no choice but to request the day off. Clutching desperately at her crotch, she fled back home with only one thought pounding through her head.
Masturbate. Right now…!
She had to. She’d already come dangerously close to chasing after random pretty women on the street more than once. Ji-yeon had no desire to become a criminal, especially not for something this ridiculous.
“Hah… ngh…”
At this hour, she figured the house would be empty. Even if that deadbeat was still home, he’d bolt to his room the second he heard anyone coming.
Quick. Hurry, hurry…!
Ji-yeon had always taken pride in her composure. It wasn’t just about looks—her grades, work ethic, even the way she spoke were all part of that image. So she needed to get inside, lock herself in her room, and deal with this foreign thing attached to her body before anyone else found out.
“Haa, hah, aaah…!!”
Alone. Without bothering anyone. That was the only way she could still face herself as the dignified woman she prided herself on being.
Beep, beep… beep-beep-beep!
She finally punched in the correct code and burst through the door—only to freeze at the sight before her.
“Ah, unnie. Welcome home.”
Waiting for her was Ji-ah, proudly displaying her erect cock, and kneeling obediently in front of her was a naked female.
Thud.
Ji-yeon’s bag slipped from her fingers.
“Ah, don’t get the wrong idea. She’s not some random girl—she’s our house freeloader.”
Ji-ah was saying something, but none of it reached Ji-yeon’s ears. All she could see was bare skin. Ji-eun’s breasts were even larger than her own, and her eyes were filled with shame… yet beneath that, a thick, unmistakable lust swirled.
Ji-yeon’s cock, already straining painfully against her pantyhose, grew even harder and thicker.
Is this a joke?
The female in front of her was beyond anything as tame as “erotic” or “arousing.” She looked utterly debauched—vulgar, filthy. Cum smeared across her face and body, drool trailing from her lips, tear tracks on her cheeks. One side of her face was flushed red from a slap, her nipples stood stiff, and her pussy juices were dripping through the fabric of her panties.
Those panties were men’s boxers—the same ones Ji-eun had worn before the change. Stretched to their limit by her newly widened hips and ass, they clung obscenely to her curves. A superior female body wrapped in male underwear. The contrast was so vulgar, so lewd, that Ji-yeon felt her mind starting to unravel.
“Haa, haa…!”
If this really was Han Ji-eun—that useless little brother—then she could solve everything right here at home. She could hide this disgusting new part of herself while finally relieving the unbearable desire that came with it.
“From that look in your eyes, you’re suffering too, huh? Hey, Han Ji-eun, open your mouth for unnie—”
Ji-yeon moved. No—she lunged.
“Y-you…!!”
She shoved the already-kneeling female onto her back and climbed on top of her.
“Kyaa!?”
“Shut up!”
Ji-ah had already broken the female in once. Now Ji-yeon was taking over. Their mindsets were completely different. The knowledge that this female had already been used made Ji-yeon’s thoughts boil red-hot.
Mine.
It was an irrational possessiveness. Never mind whether it was right to feel that way about another person—Ji-ah had found her first. But none of that mattered now. All Ji-yeon felt was jealousy. A male’s fierce, unreasonable jealousy toward anyone else touching what he wanted.
“Wait, unnie! I’m using her pussy first!”
Ji-ah felt the same jealousy. She wanted to claim this female’s virginity herself. The first one to tear open that virgin wrapper and shove her cock into that sopping hole should be her—because she was the one who discovered and tamed this female. But her words backfired. They confirmed that Ji-eun’s pussy was still untouched.
“Shut up!!”
Ji-yeon roared—crude, undignified, nothing like her usual self.
“You already used her once!!”
It was exactly like when they were kids fighting over a toy. Only now the toy was their former brother, Han Ji-eun, turned into a female.
“I haven’t even used her pussy yet!!”
The need to relieve their desire, the overwhelming intensity of that desire, the rough words and actions—it was all the same for both of them.
“Just use her mouth, unnie!”
“Because you already dirtied it!”
“It’s not dirty, it’s trained, you fucking idiot!”
In a physical fight, however, Ji-yeon already had the advantage—she was pinning Ji-eun beneath her.
“Shut up!! I… I’m…!!”
Ji-yeon’s breathing was ragged, her eyes wide and bloodshot. Suddenly, a sob tore out of her.
“Hic… hngh…!!”
The unbearable lust, the jealousy, the resentment toward her sister who refused to yield even after already getting off once—it all came pouring out.
“U-unnie, are you crying…?”
Ji-ah faltered at the unexpected sight. Then Ji-yeon yanked her pantyhose halfway down, and what sprang free made even Ji-ah’s eyes widen.
“…Whoa.”
“…Ah.”
The female could only stare, entranced.
It’s huge.
Ji-ah’s own cock was large, but Ji-yeon’s was something else entirely. Top one percent. A monstrous shaft that dwarfed even Ji-ah’s impressive size, thick veins pulsing as clear precum dripped onto the female’s stomach. Ji-eun’s gaze locked onto it, hypnotized.
Really… huge.
Ji-ah had thought her own size was already excessive—some women might not even be able to take it no matter how much they were loosened. But this was bigger. It was almost as thick as the female’s slender wrist. The sight of dignified Ji-yeon in tears, combined with that massive cock, completely defused the argument over who would take Ji-eun’s virginity first.
In that charged silence, Ji-yeon spoke first.
“Hic… hngh… I’m sorry…”
She was apologizing to Ji-ah, not Ji-eun.
“S-so… let unnie go first…”
“Nngh…”
Ji-ah bit her lower lip. She could feel the raw, desperate need radiating from her sister’s eyes and throbbing cock. Having just experienced that same hunger herself, she couldn’t bring herself to refuse after Ji-yeon had already apologized. The two sisters had always been close. Ji-ah could have just taken Ji-eun without caring about Ji-yeon’s arrival, but she hadn’t—because she’d been worried about her suffering older sister.
“Tch.”
Finally, Ji-ah backed down.
“You owe me one, got it?”
She could accept it. Even if she gave up the pussy’s virginity, she had still been the first to claim Ji-eun’s mouth and throat. It was fair enough. And having her sister owe her a favor wasn’t a bad deal either.
“Y-yes, yes!!”
Ji-yeon nodded frantically, just like when they were kids making up after fighting over toys. With no other male to interfere, her gaze dropped to the female still pinned beneath her.
“Hic…”
Ji-eun trembled as their eyes met. The conversation above her had been humiliating—two sisters casually deciding who would take her virginity while completely ignoring her own feelings. Treating her like a toy. Like a tool whose only purpose was to relieve their lust.
But if someone asked whether Ji-eun resented that treatment…
“Hnnngh…”
Her heart pounded wildly at the sight of her sister’s burning, lust-filled eyes. Her gaze, unable to hold that stare, dropped instead to the massive slab of meat that would soon claim her virgin hole—the cum-injecting rod, the disciplining club.
“Haa… haa…♡”
The way she looked at it answered the question clearly. She had no complaints about their decision. And now that Ji-yeon had secured both her sister’s concession and the female’s submission, she moved to finally relieve her first male lust.
Her fingers hooked into the last piece of fabric covering the female’s crotch—the soaked men’s boxers, so drenched they looked like they’d been pulled straight from water.
