Dreamlike Pleasure Over Guilt
"Hah... hah..."
With the dildo jammed into the floor, she shook her hips wildly, lost in the rhythm.
"Haa... fuck... haa..."
The half-assed pleasure felt like torture from hell, so even as she masturbated like a slut, curses spilled from her lips.
"Oppa... Oppa! Why... why...!"
Oppa's erections had come back. Not quite like before, but big and hard enough to satisfy, and his recovery was quick too.
"Fuck... why... why...!"
Unfortunately, Oppa always came too easily, like he was only satisfying himself. No matter how fast his recovery or how good his stamina, doing it four times in a row was apparently too much.
It made her thrilled that her body turned him on and satisfied him. But separately from that, her own lust just kept building.
The lingering, ambiguous pleasure gnawed at her body, and resentment toward Oppa started to pile up bit by bit. On top of that, lately she couldn't even dream of having sex with Ha-jin.
When the brothers left for work, she spent her days barely able to focus on anything, just masturbating to kill time.
She masturbated because it was too agonizing, did half-hearted housework and then masturbated, masturbated out of resentment toward Oppa... And the more she did, the less satisfied her body felt, leaving only scorching heat behind. That afterglow drove her even madder.
"Hah... haa... just a little more... and... hngh...♡"
Every morning, her body burned hot. Her nipples stood stiff enough to embarrass Oppa when he came for his morning greeting, and she had to wear pads again because she was soaking wet... Her body was hypersensitive and aroused, but no matter how much she masturbated, she couldn't cum satisfyingly.
"Heuk... heuk..."
Ridiculously, after masturbating like a maniac, she'd exhausted her stamina instead, sprawling on the floor and panting roughly.
"Whoa... today's extra vicious. Even a stray bitch in heat wouldn't go this far."
She slowly lifted her head toward the voice, her exhausted body feeling like her heart might burst out of her mouth like after brutal exercise. There stood Ha-jin, looking at her ridiculous, collapsed form like he was eyeing a dead cicada on the street, mocking her pathetic state.
She'd collapsed mid-masturbation without even cleaning up... She'd never let Oppa see her in such a vulgar mess...
But ignoring those worries, just seeing his face made her relax and get aroused.
Ah... finally... Am I going to dream of doing it with Ha-jin now...? He's wearing the same clothes he left in this morning... Is this a dream...? If it's not... this is really bad...
"If you don't like what my brother does, want me to help you out like always?"
Like always... Yeah... this is a dream. The dream that always makes me feel good. Finally, I'm dreaming again... Finally meeting Ha-jin in my dream... I can calm this arousal now...

"Oppa... put it... in here..."
Her body still trembled weakly from depleted stamina, but with the dildo still lodged inside, she lifted her pussy toward Ha-jin and shook her hips.
"Wow...! Never thought you'd turn this slutty. You've got real talent as a whore."
She could see him quietly entering the study, rummaging for something. She begged him to hurry and fuck her, but her body wouldn't obey.
"Come on, shake those hips vulgarly to the beat of our metronome? Do it right, and I'll make you feel good."
Ha-jin lit purple incense beside her and started the metronome.
Shake my hips vulgarly...? Her mind filled with questions, but at the same time, she understood exactly what to do.
Tick... tock... tick... tock... Hearing the metronome made her even hornier than before.
Her mind pictured the action, and sure it was embarrassing, but the pleasure she anticipated outweighed it. Without hesitation, she decided to shake her hips.

"Oppa... please shove your cock into slutty, lewd bitch Hye-won...♡"
Squatting with legs spread wide, hands clasped behind her head, she shook vulgarly. She matched the metronome's rhythm, her extremely aroused and exhausted body shaking uncontrollably. Her breasts jiggled with the recoil, the motion stimulating her pleasurably.
Ha-jin took off his pants and approached. His fully swollen cock reeked of precum and sweaty musk. He brought it close to her face, pressing it against her nostrils.
Without thinking, she licked her lips, craving to taste it.
"You keep calling me 'Oppa,' so say clearly who I am, right?"
Ah... even in the dream, he makes me do such wicked things... If I acknowledge exactly who he is, even in a dream it'll be real cheating...
That rationality washed away, soaked by the lewd, fishy smell rising from under her nose.
"Hngh... hah...♡ Ha-jin... Oppa... haa... your smell...♡ I wanna suck it..."
She'd said it... "Oppa" was reserved for her husband, Ha-jun Oppa... But... but... it's a dream now... Not reality, so it's fine. Oppa’s the bad one. He always cums alone feeling good... Leaving me suffering like this... I'll give my body to Ha-jin Oppa now, Oppa...
"You want my cock that bad? Even cheating on him?"
Ha-jin Oppa rubbed his cock on her face or tapped her cheeks. When his heavy balls rested on her nose, the heat and smell dazed her mind like it was drugged...
"Hehe... Oppa... ahn... cock... wanna eat it...♡"
Shhhhaaa— drip... drip... slurp... The vulgar smell from his cock pushed her intensely aroused body to the peak she'd craved so badly.
Her body, shaking vulgarly and desperately, toppled backward, sprawling like a dog begging for belly rubs.
"Hah...! Haa... haha...♡ I came... just from the smell... hehe...♡"
She'd cum from just the smell, but it was on another level from the sex Ha-jun Oppa gave her. She wanted to taste that pleasure again.
Tick... tick... Droplets fell into her mouth, still agape from ecstasy. Heat surged hotter through her body, pussy squirting fluid like urine.
"Kyaa...♡ Haaang..."
Her body was utterly exhausted, stamina drained, but her lewd ass still flirted with Ha-jin Oppa, craving more pleasure. Unconsciously, she prostrated toward his cock, ass raised high, grinding her soaked pussy.
Pfuk—

Shhhhaaa—
"Kyaaang...♡"
Ha-jin Oppa suddenly thrust his cock deep inside. Whether from desperate need or extreme arousal, she felt every inch of his cock probing her pussy's depths.
The unpleasant thick veins, the slight curve of his shaft, the bigger, more prominent glans than Ha-jun Oppa's... Every movement stimulated her sweet spots inside.
His balls slapped her clit with each thrust, his hot breath whispered in her ear—every element aroused and pleasured her, making her cum easily.
"Whose cock feels better? My brother's? Or mine?"
What a sly guy. The answer was obvious—why ask?
"Ha-jin Oppa's... yours feels better...♡"
"We're twins, so our sizes are about the same. Guess he doesn't satisfy you?"
"I was waiting for sex with Ha-jin Oppa... Feels better than with Ha-jun Oppa...♡"
This was a lie. Empty words to make the sex feel better... It's a dream... I haven't betrayed Ha-jun Oppa yet...
"Weren't you the one who hated me? Made it so obvious, but you waited for my sex? Hilarious."
She was speechless. Yeah... she had hated and despised him. One word would satisfy what Ha-jin Oppa wanted, but she didn't want to say it.
Slurp... smack...
"Hngh...♡ Haaang... lick... slurp... smack... pfua...♡"
Ha-jin Oppa's kiss... Felt so good... Her body shivered. Breasts throbbed... Yeah... this feeling... I'd felt it before... With Ha-jun Oppa...
"I love you... Ha-jun Oppa...♡ I love the Oppa who makes me feel good...♡"
This... is a lie... Because Ha-jin Oppa wants it... So it feels better...
"You like me more? Heh... then you'll love me even if I fuck you till I'm satisfied?"
Ah... Ha-jin Oppa’s smiling... Feels good... It's a dream... I can love him in dreams, right?
Tick... tock... tick... tock... Ha-jin Oppa brought the metronome right next to her. The clearer sound made her pussy clench tighter with arousal and pleasure.
Regardless of her will, the tightening let her feel his cock's shape more vividly—too good.
"Hii...♡ Feels... so good..."
Uncontrollable arousal and pleasure shattered her last remaining reason.
"Kyaaang... Oppaaa... love it... feels so good...♡"
She clung to him desperately, whispering the love she'd only given Ha-jun Oppa, cumming and begging for more sex.
"A bit more...♡"
Her body had reached its limit—vision blurring, the world tinting yellow. Still, craving pleasure, she clung to Oppa until stamina gave out amid orgasm, blacking out.
Sniff...
"Kahat...!"
Suddenly, a vinegar-like ammonia stench stabbed her nostrils like poured directly on her mucous membranes, jolting her awake.
"Ha...! Wha...t..."
"I haven't even cum yet—think you can pass out after pleasuring yourself?"
Ha-jin Oppa thrust even rougher. His cock stabbed her pussy, slamming her cervix— the pleasure hitting her brain directly.
"Kyaa... kyaang...♡"
Felt like his cock was raping her brain too. She tried to escape into orgasmic blackout again.
Sniff...
"Kyaang...♡ No... stop now..."
Smack— smack— Consciousness returned. Ha-jin Oppa spanked her ass like punishing a fainted girl. His cock kept thrusting, forcing pleasure in.
"Smells intense, right? Smelling salts—athletes use 'em. Wakes you right up. Pretty good stuff."
Every time she blacked out, Ha-jin Oppa revived her with smelling salts, over and over.
She lost count of her orgasms. Couldn't even tally them.
Only after Ha-jin Oppa came about five times with condoms did she barely escape that orgasmic hell.
"Hiek... hiit... hehe...♡"
Freed from the pleasure she'd desperately wanted to escape, yet her pussy still squirted fluid, craving it.
The metronome's endless tick-tock brought arousal back.
"That's enough for today? Beg my brother for the rest."
With those laughing words from Ha-jin Oppa, her exhausted body fled into sleep.
"Hng...♡"
She woke from a light orgasm. Her pajama pants were soaked. Her body ached like she'd been beaten.
Ha-jun Oppa stared at her beside her.
"What dream made you... react so lewd and seductive...?"
Ha-jun Oppa smiled shyly. His lower half bulged obviously.
He wanted sex with her again today...
"Hey... wanna... do it today too?"
Oppa cautiously asked for sex. Seeing he couldn't last 1-2 minutes, it must've felt good for him. But his awkward smile and words grated on her like unpleasant noise.
"Sorry, Oppa... I'm too tired..."
Anyone could hear the irritation in her voice.
For the first time, she refused sex with Ha-jun Oppa. She'd always begged him first...
But she felt no guilt at all.
Sex with Oppa was surely less pleasurable than Ha-jin Oppa's in the dream—
"It wouldn't feel good..."
"Ah... yeah... Sorry, you were tired..."
Oppa carefully pulled the blanket over and turned his back to her.
