The In-Laws' Lewd Discipline
The room was bathed in a dim, suggestively pink glow.
Whirrr. Whirrr~~ Whirrrrr~
The soft, buzzing vibration of the electric dildo filled the air.
Schlick. Squelch. Sluuuurp… Schlick!!
The obscene, wet sounds of fluids gushing as the toy plunged in and out of her pussy.
“Haaah… Hnghh… Aaaahn!!”
The mother-in-law’s moans rose each time the massive dildo drove into her.
Naho hung lewdly from ropes bound to the ceiling, her body glistening with sweat. Daegun, her father-in-law, slapped her plump ass with his thick palm, scolding her even as he fucked her.
Slap!! Slap!!!
“Haaang!!! Aaang!!”
Despite the sharp sting and the pain, Naho’s face flushed crimson, her lips trembling as she smiled in ecstasy. Saliva and slick nectar dripped steadily from both her mouth and her dripping cunt.
“Haaang… Darling♥ More… give me more!”
Daegun chuckled and moved around to her front. He seized a fistful of her hair, tilting her face up to meet his gaze.
“You’re being punished right now. Just how the hell did you raise our son that things ended up like this?!”
“And you! A daughter-in-law who can’t even support her husband and instead drags him even deeper into the abyss… Tsk tsk!!”
The words were harsh rebukes about their son and daughter-in-law’s failures, yet neither of their faces held any real severity. They looked like children lost in a delightful game.
Daegun was clearly savoring every second. Naho, trembling with uncontrollable arousal, answered in a voice thick with pleasure.
“Hnghh… I’m sorry…♥”
Yeojin, hidden and watching her in-laws, felt her mind spin from the dizzying mix of shock and forbidden excitement.
“Looks like you still haven’t reflected at all.”
Daegun circled back behind her. He pulled the dildo from Naho’s pussy with a wet pop, licked its glistening length, then positioned his own cock at her entrance.
What the hell is that?!
Yeojin’s eyes widened in disbelief. Even from a distance, her father-in-law’s cock was noticeably larger than her husband Sekyung’s, standing rigid and proud.
It resembled a thick, perfectly grown branch—veined, heavy, and imposing.
That’s a penis? It’s nothing like what I know… The shape, the size… completely different from Oppa’s… Is he even Asian?! It looks more like…
Yeojin’s entire sexual experience had been limited to Sekyung. She had never seen another man’s cock in real life. With almost no exposure to pornography, the raw, intense scene unfolding before her—and the sheer size of Daegun’s manhood—hit her like a thunderbolt.
Besides, isn’t Father turning sixty this year? How can he possibly…
She was still reeling from the sight when Daegun drove his massive length into Naho in one brutal thrust.
“Huuuuuuuugh! Ooooooh!!”
Naho’s belly visibly bulged outward. From her elegant, beautiful form came a guttural, animalistic cry that seemed impossible. Her eyes rolled back, body arching into a tight U-shape as overwhelming pleasure tore through her.
She shook violently.
Something that huge… went all the way inside her?!
Then the real frenzy began.
Thud. Thud. Thud. Thud.
Squelch—squelch—sllluuurp—schlick—
“Ooooooh!!! Haaauuuugh!! Haaaaah! Uuoooh!!”
The room echoed with the wet slap of flesh against flesh and moans that sounded less like human pleasure and more like the roars of beasts in heat. It was the kind of raw, unrestrained noise one might hear in foreign adult films.
The sight of her usually graceful, refined, and elegant mother-in-law completely undone made Yeojin’s own pussy unbearably wet.
That mother-in-law… making faces like that?
To Yeojin, sex had always meant a tender act of love—mutual affection, gentle touches, sweet kisses. That was exactly what she shared with her husband: soft, happy, and full of warmth.
But her in-laws’ sex was something else entirely.
There was no gentleness here. Only raw intensity.
Even someone like Yeojin, with limited experience, recognized it immediately—SM play. The very thing she had once found disgusting and incomprehensible.
Yet now, watching them, all those negative feelings had evaporated.
Strangely, their actions looked incredibly lewd, joyful, and blissful.
Does it really feel that good?
Naho’s bound body swung back and forth like a swing, her heavy breasts bouncing so violently it seemed they might fly off. The wet, rhythmic sounds of their bodies colliding filled the air—squelch, smack, slap, splat.
With every thrust, Naho cried out in ecstasy.
“Ooooh! Haaauuht! Haaaaaaaah! Haaaaah♥”
Her pussy overflowed, juices pooling on the floor beneath her. She was cumming repeatedly even as he continued to pound her.
Daegun fucked her mercilessly while spanking her ass.
Smack! Smack!!
“That boy Sekyung didn’t just inherit your looks—he inherited that same airheaded side of you too!”
Naho panted, gasping out an apology.
“Hnghh!! S-sorry… darling…♥”
“That’s—”
Daegun raised his hand high.
“Not the attitude of someone who’s truly sorry!”
Slap!!!
“Huuuuuuuht!!!”
Naho’s right ass cheek burned bright red, yet the pain only seemed to heighten her pleasure.
“S-sowwy…♥”
Her tongue had gone slack from overwhelming sensation, slurring her words. Daegun gazed at her with fond satisfaction, then leaned down to whisper hotly in her ear.
“Still… I love both you and our foolish son.”
“Huuuung♥ Darling♥”
His sweet words sent fresh waves of arousal through Naho.
Daegun picked up the dildo again.
“But a punishment is a punishment. I’ll discipline you with the thing you love most.”
He sucked the toy thoroughly, coating it in saliva, then slowly pushed it into her tight anus.
Sluuuuuuurp~
“T-that place is too sensitive…!!”
“O-oooooh! Ooooooh!!”
He resumed thrusting his hips while simultaneously working the dildo in her ass with equal force. Naho’s moans grew even wilder.
“Hnghh!! Ooooooooh!!!”
Yeojin received another shock.
Even that hole?! That’s not supposed to be used for this!
Yet the expression on Naho’s face as she cried out was one of pure rapture.
“Darling! Aaang!! It feels so good there♡ Harder…! Fuck me harder!! More violently!!”
“I told you this was punishment. You like it that much?”
“Haaang…! It feels too good♥”
“Which feels better? Your pussy? Or your ass? I’ll fuck whichever you prefer.”
“Hnghh…♡ Both… I love both of them!”
“Such a greedy girl.”
Naho looked utterly, blissfully happy.
That happiness planted a seed of doubt in Yeojin.
Could it really feel that good?
That place… is where she goes to the bathroom…
“Haaht…!”
Schlick… slurp… squelch…
Slide… squish…
“Haaang…♡”
Without realizing it, one of Yeojin’s hands had risen to caress her own soft breast, pinching the nipple hard. Her other hand rubbed frantically at her swollen clit before two fingers plunged into her soaking pussy, pumping with desperate intensity.
Her cunt was drenched far beyond anything she had experienced before. The lewd, wet sounds of her own masturbation—schlick, splat, splash, sluuurp—echoed in her ears.
Hnghh… Huuuuuuht…♥
Her movements grew more frantic, matching the escalating rhythm of the couple before her. Both sides were rushing toward climax.
They came together, biting back their loudest cries.
Haaaaaaaang♥
“Ooooooooh!!! Huuuuht♥”
Naho hung limp from the ropes, fluids still dripping from her body. Daegun, still buried inside her, grabbed a handful of her hair and lifted her head.
“Honey, it’s nice that you came so spectacularly, but I haven’t finished yet, have I?”
Naho’s eyes were half-glazed with pleasure.
“S-sowwy…♥”
“Since this is punishment, you don’t get to rest until I cum.”
“Ehh…♥ (Yes♥)”
They immediately began another savage round.
Meanwhile, Yeojin—unlike the tireless couple—sat trembling in the afterglow. Sweat trickled slowly down her neck as soft, lingering moans escaped her lips.
With her face burning, she stared at her drenched pussy and glistening right hand. A storm of emotions she had never felt before swirled inside her chest.
The afterglow didn’t last long.
She snapped back to reality, cheeks blazing with shame, and fled the scene as if escaping a crime. She slipped back into the bedroom where her husband slept.
Once inside, Yeojin didn’t even change out of her soaked clothes. She dove under the blankets, pulled them over her head, and relived the shocking events of the night.
What on earth did I just do?!
Ugh…!! How am I supposed to face the two of them tomorrow…?
She tossed and turned in agony until exhaustion finally pulled her into sleep.
*****
By the time Yeojin had fallen asleep, Daegun had finished with Naho. He laid her unconscious form gently on the bed and was heading out for a drink of water when he paused.
“Hm? The door was open? I must have forgotten to close it properly… Guess I really am getting old.”
As he scolded himself for the oversight, his eyes caught something else on the floor.
“?! This is… liquid?”
It was the puddle of Yeojin’s juices.
Daegun immediately understood what it was.
“No way…”
