Miyeon's Body with Amplified Sensitivity
A short while before heading to see her exclusive physician for an examination under the dedicated contract, on the very evening she had fought alongside Kang Cheonhu, Miyeon found herself wrestling with her inexplicably heating body without realizing it. Her temperature was abnormally high, and her face kept flushing hot.
"My body's acting a bit strange. Is it just fatigue...? Ahh, so hot. I need some water."
But Miyeon didn't think much of her condition yet. It wasn't particularly hot weather, but her body felt feverish, making her perceive heat everywhere. She slipped into short dolphin pants and a thin t-shirt, then headed to the shower attached to the living room.
"Ugh, uwaaah! S-Sis!"
Coincidentally, Jinseok was showering in there. Her head foggy from the rising heat, Miyeon hadn't noticed anyone inside. She ended up face-to-face with her fully naked brother.
"Kyaa! S-Sorry!"
She caught sight of Jinseok's well-trained muscular body from his diligent strength training, and even his dick dangling amid the thick bush of pubic hair. Letting out a cute scream, Miyeon quickly turned her head and bolted out of the shower.
"S-She just barged in... Sis saw me naked... So embarrassing."
After finishing his shower, Jinseok emerged awkwardly, slipping into his pajamas. Though facing Miyeon was mortifying, he couldn't stay in there forever. Reluctantly, he stepped out into the living room, cheeks burning.
Miyeon sat blankly on the living room sofa, staring at the TV as she waited.
"S-Sis. Sorry."
"N-No, it's me who should apologize. I didn't knock. Sorry."
Miyeon felt just as embarrassed seeing Jinseok naked, fidgeting on the sofa. Though they were siblings, years apart had kept them from being completely casual with each other. The awkwardness hung in the air; she couldn't even bring herself to shower.
"Sis, want some juice?"
"Yeah, sure."
To break the tension, Jinseok went to the kitchen and poured orange juice into a glass, bringing it over. Standing by the fridge, he stole glances at Miyeon in the living room. Instinctively, something about her seemed different today. Her flushed face, the thin white t-shirt so sheer it hinted at her skin beneath. Her breasts, slightly swollen from arousal, made her nipples stand out prominently under the fabric. The short dolphin pants accentuated her slender, alluring legs even more.
(Am I imagining it...? Sis looks extra... today.)
Jinseok already thought Miyeon dressed a bit carelessly at home, and he'd gotten aroused by her before, but today she seemed even sexier.
"Here, drink up."
"Thanks."
He handed her the juice and sat beside her on the sofa. As soon as he did, her sweet fragrance tickled his nose. Sitting next to Jinseok made Miyeon's lower abdomen tingle strangely. She couldn't help but think of his naked body, catching his masculine, musky scent. To ease the itchiness, she kept crossing and uncrossing her legs, switching sides repeatedly.
Gulp!
Seeing her milky thighs shift so seductively, Jinseok swallowed hard. He knew the dolphin pants hid what lay beyond, but the way the fabric wrinkled made it thrilling, like her intimate parts might peek out any second. Her usual pleasant, fragrant scent felt thicker now, almost like her body was emanating a seductive, erotic aroma.
Throb!
(Ugh! Looking at Sis and my dick's getting hard again! Why is Sis so...)
Without warning, Jinseok's cock stiffened. Self-loathing hit him—he was erect for his own sister again. He hunched over awkwardly, trying to hide it.
"Sis. I-I'm heading to bed early. G-Goodnight."
"Yeah. Sleep well."
Bending at the waist to conceal his erection, Jinseok dashed to his room. Usually, he jerked off thinking of Serin, but tonight Miyeon joined those thoughts.
"Ahh! Sis! Sis! Why are you so defenseless and sexy! Ungh!"
...
"Still too hot. Gotta shower with cold water."
Once Jinseok went to bed, Miyeon entered the shower and turned on the cold water. Her body burned so fiercely she wanted to douse it and cool off.
Shooooosh!
"Ah! Ahhng!"
But the moment the cold shower stream hit her body—especially her breasts and between her legs—a lewd moan escaped her lips unbidden. It was just the water pressure, yet she felt it intensely, hypersensitively.
"W-Why...???"
Though she sensed her body had grown unusually sensitive during the shower, Miyeon didn't realize her nerve sensitivity had been dramatically amplified.
"Even after showering... it's no use."
Despite the cold water, her body still felt scorching. Resigned, she dried off and went to bed.
"Mng! Ah! Haaah!"
Lying down to sleep proved futile; her body kept heating up uncontrollably. Her breasts, ass, and the itching ache between her legs—her pussy—tormented her.
"Haaah! Uuung!"
Unable to endure it, Miyeon slid a hand between her legs and began masturbating. She wasn't a complete stranger to it, but her natural low sex drive and disinterest meant she rarely did. Her hero training had taught her to suppress emotions, including lust.
"Ah! Ahng! Ahhng!"
One hand rubbed around her pussy, the other fondled her breast. Inexperienced, she just ground against the entrance without penetrating. But her sensitized body surged with arousal anyway.
"Haah! Haaang! Hauung!"
Her eyes glazed over mistily, lips parted with sweet breaths. Her flushed expression was worlds away from the cold, blade-sharp Sword Princess she usually embodied. Now, her face was that of a bitch in heat, lost to ecstatic pleasure.
"Ahhat! Hauung! Hauut!"
Her mind fogged too, sharp intellect crumbling into a dreamy haze. Lewd fantasies flooded in—ones the old Miyeon would never entertain. Naked men. Especially Jinseok's body from moments ago lingered vividly.
He was the man she'd seen most undressed. His swimsuit-clad pecs and abs, thick muscular limbs danced in her imagination. And that hairy, swinging cock from the shower...
"Ahh... Jinseok... Ahh!"
She pictured his dick swelling huge, his naked body pinning her down, slamming that erection into her pussy and ravaging her. Unknowingly, she'd grown desirous of Jinseok.
By bizarre coincidence, the siblings lay separated by a thin wall, both masturbating while thinking of each other. If Jinseok had acted on his urges and rushed to her room right then, she would've fucked him instantly.
"N-No. Am I crazy? I-I can't look at Jinseok like that... Ahh...!"
Shaking her head, Miyeon forcibly banished the image of his naked form. Her taboo awareness of incest suppressed the fantasy. Though she'd quashed thoughts of Jinseok, her burning lust persisted, and she kept masturbating. Her delusions shifted to another man.
