Su-yeon's Heat

Around 3:20 a.m., Su-yeon woke up. Lately, she'd been jolting awake at this exact time every night.
Snore~ Puff~
Min-jun, who must have slipped into bed without her noticing, was snoring away beside her. Su-yeon felt a twinge of resentment toward him.
He's been using overtime as an excuse to avoid me lately... We're married, for God's sake... Even if it's small... I want it...
She started to pinch the sleeping Min-jun to wake him, then stopped herself.
He's exhausted. Let him sleep a bit more...
Su-yeon sat up and headed to the fridge, opening the door. It was packed with beer cans.
Guess I'll have one of these...
She grabbed a can.
Crack—hiss—fizz
In the quiet house, the sound of the tab popping rang out louder than usual. Su-yeon chugged it down in one go.
...Something's just not filling the void...
She slipped into the bathroom and stood before the mirror. Her silk pajamas clung to her body, and her nipples poked faintly against the fabric over her full breasts.
Am I not attractive enough...?
Su-yeon unbuttoned and shrugged off the top. Her breasts were flawless compared to anyone else's, paired with a slim waist. She caressed them with her hand, teasing her nipples. Just that touch ignited her arousal almost instantly.
I can't take it anymore...
She stripped off her bottoms and panties, folding them neatly in front of the shower, then retrieved the dildo hidden in the bathroom cabinet. Lying back in the tub, she raised her knees, spreading her legs wide. She positioned the dildo at her entrance and eased it in slowly.
"Ah... aang... ha..."
Su-yeon pushed it all the way in.
"Ah... aang... so... good..."
She began sliding it in and out slowly, moaning softly.
"Ah... ah... haa..."
She picked up the pace, one hand rubbing her clit.
Squelch—squeak—squelch—tzztz
"Aang... haang... haang..."
The bathroom filled with her moans. Climax approached fast—her back arched sharply. Love juices leaked from her pussy, soaking the dildo. Craving more intensity, she angled it to target her G-spot.
Squelch—squeak—squelch—tzztz
"Haaang..... haaang...."
Her moans grew louder, the wet sounds more frantic.
"Haaang..... haaang.... feels so good... I'm gonna cum..."
Her hips bucked harder. Pressure built in her groin.
"Haaang..... haaang...."
Splash—spurt—spurt—
Squirt erupted from her urethra.
"Ha... ha... ha..."
Lost in the rare, deep orgasm, Su-yeon lay there panting.
"Ha... ha... ha..."
Savoring the afterglow, she stared at the ceiling. After a while, she came to her senses and showered off the fluids coating her body.
Shower~
The hot water washed away her built-up stress and depression. Clean now, she slipped back into just her pajama top—no panties—and returned to the bedroom. 4:10 a.m.
Snore~ Puff~ Snore~ Puff~
Min-jun was still out cold, snoring obliviously.
Worse than a damn dildo...
Su-yeon wanted to kick his ass. What's the point of having it if it doesn't work? Maybe force him to get snipped...
Or just rip his pants off and ride him...?
The urge to strip the sleeping Min-jun and take what she wanted surged through her, but it faded quickly.
No... sleep. Gotta be sharp tomorrow...
With that, she crawled back into bed and drifted off.
7:30 a.m. Morning sun woke Su-yeon. Min-jun, who had been snoring beside her, had already left for work early.
Out the door at dawn again...
She headed to the living room to prep for work. On the table sat a note in Min-jun's handwriting.
"Heading out first. Thanks for everything, as always."
Su-yeon glanced at it indifferently.
Always just empty words...
She tossed it in the trash. Grabbing water from the fridge, she drank it down to clear her head. She washed her face, shampooed her hair, dressed hurriedly—a pale pink blouse and gray skirt.
7:55 a.m. She left for the subway station. The platform was already packed with commuters.
"The outer-loop train bound for Seoul National University Entrance is now arriving. Please wait until all passengers have exited before boarding safely."
The train rushed in from the left.
Rumble~ Screech~
"Safety doors opening. Watch your step! Watch your step! Watch your step!"
People surged in like a wave. Su-yeon got pushed inside by the crowd.
Beep-beep-beep~ Doors closing. Doors closing. Toot~
"Next train will stop at the platform ahead. Please board the next one."
Beep-beep-beep-beep-beep. Safety doors closing. Please stand back.
Everyone was crammed tight, barely able to stand. Su-yeon was no exception. Rush hour toward Gangnam Station was always hell. The train rocked as it sped along.

Hmm... something's pressing against my ass...
Something poked at Su-yeon's butt. It hardened and grew, wedging fully into her ass crack.
Clunk... clunk...
With every jolt of the train, it slid up and down her cleft, sending thrills through her.
Hmm... hmm...
She clamped a hand over her mouth to stifle a moan. Careful not to draw attention, she glanced back. A guy in his mid-20s stood there. Embarrassed at the sight of his face, she turned away.
Hmm... hmm... Bigger than Oppa Min-jun's... If Oppa's was this size... haang...
The sexual shame paled against the excitement of this larger cock—belonging to a stranger—grinding her crack. Her knees weakened, waist dipping forward slightly under the rising heat. The man behind her tried awkwardly to pull back, but the packed train made it impossible. It only twisted his posture worse, now prodding toward her crotch, pressing even tighter.
Haang... haang...
His dick stabbed at her pussy through their clothes. Though fabric separated them, the rigid shaft pressing her folds was enough to drive her wild.
Clunk! Clunk!
The train lurched, thrusting it harder. He kept trying to retreat, but it only stimulated her more.
"Haang..."
A tiny moan escaped Su-yeon's lips. She couldn't hold it even with her hand over her mouth.
"Ugh... haa..."
The man behind her let out a soft groan too. The noisy car drowned it for others, but she heard it clearly.
"Haang...."
Another moan slipped out. Sweat soaked her blouse, her bra visible underneath. Her pussy leaked juices, dampening her panties and skirt.

"Clunk"
"Haang...."
"Haa..."
"Clunk"
"Haang...."
"Haa..."
She moaned in rhythm with the train's jolts.
Ha... it feels so good... haa... Anyone... just fuck me already... ha...
Her frustration from the sexless marriage fueled it—whoever it was, she'd take it.
"This station is Sadang, Sadang Station. Doors on the left for exiting."
Whirr—hiss
"Doors opening. Doors opening."
A horde disembarked at Sadang. The man behind her bolted out too. Su-yeon's legs gave way, and she slumped down.
Haa... haa... haa...
"Hey, missus... you okay? You look faint—sit here..."
"Ha... Granny... aren't you... uncomfortable... you sit..."
"No, no. You're the one gasping like you're about to pass out. Take the seat~"
"Ha... thank... ha... you..."
The elderly woman in front of her stood, offering her seat. Su-yeon collapsed into it gratefully and closed her eyes.
Ha... I wish he'd finished me... If it had been Oppa Min-jun's... haa...
The shame was overshadowed by the thrill of that young, bigger cock rubbing her—and the regret that it wasn't her husband's.
"This station is Yeoksam, Yeoksam Station. Doors on the right for exiting."
The train neared her stop. Su-yeon pulled herself together and opened her eyes.
Time to work... ha... such a shame... Oppa Min-jun... I want it... I don't know what'll happen like this...
Whirr—
"Doors opening. Doors opening."
The doors parted, and Su-yeon escaped the train, emotions swirling.
