Over the Edge
A little time had passed since Daegeun left the house.
Inside the playroom, Yeojin’s suppressed moans mingled with the faint, persistent hum of the vibrators.
Bzzzzzzzzzzzz—
Bzzzzzzzzzzzz—
Bzz-bzz-bzzzzzz~~~
“Mmph…! Uuup……!”
Perhaps because not much time had passed, Yeojin was still managing to hold on.
It’s still bearable… But how long can I keep this up…?
Unease gnawed at her.
The blindfold left her in total darkness. Depriving someone of sight inevitably sharpened their other senses and stirred up anxiety.
She had no concept of how much time had slipped by. The gag in her mouth kept her from speaking. This was all new to Yeojin, and the psychological strain was immense.
Being bound and continuously stimulated at every erogenous zone by vibrating massagers and rotors was already overwhelming. On top of that, they had administered an enema, however small the dose. The medicine was slowly taking effect.
What’s more, the anal beads sealing her rear were equipped with vibration functions of their own. The tremors spread through her entire body, feeding her pleasure in a steady, rising tide. The longer it went on, the harder it became to endure.
People usually adapt to constant stimulation. But Daegeun had calculated for that too. He had programmed the devices attached to Yeojin’s body so their intensity would shift constantly, never allowing her to grow accustomed to the sensation.
Thanks to the carefully timed vibrations that delivered just the right amount of pleasure and the creeping effects of the enema, Yeojin grew more and more distressed.
How long has it been? It’s getting harder… When is Father-in-law coming back…?
“Huuup…!”
Click.
Someone had entered the room.
“!!”
Is it Father?
Yeojin’s guess was wrong.
“You’re holding up well.”
Mother-in-law?!
At the sound of Naho’s voice, disappointment and shame flooded through Yeojin.
“Uuuup?!”
Naho approached the bound woman.
“He asked me to check on you from time to time.”
“!”
“If it goes on too long you start adapting, and it becomes harder to feel anything.”
No way…!
“So I’m here in Segyeong’s father’s place~”
“Uuuup!!!”
Just as I thought…!! I knew Father wouldn’t simply leave me like this, but to drag Mother into it…
Naho ran her hands lightly over Yeojin’s restrained body. The sudden touch made Yeojin flinch.
“!!”
“I’m jealous. These days he’s so busy with you that he barely touches me anymore.”
Even if you say that… I want to stop!
Yeojin burned to argue back, but since she couldn’t speak, the complaint stayed locked inside her heart.
“You must be full of resentment.”
That hit close…
Naho spoke as though she truly understood how Yeojin felt.
“It won’t be long for you, either.”
“Uup?”
Naho’s face wore an ecstatic smile.
“It won’t be long before you fall completely to him.”
“!!”
Yeojin could not comprehend it. She could not understand how Naho could remain so calm while her own husband violated another woman—his own daughter-in-law, no less.
Wiiiiiiiiiiiiing~~~~
A new, different vibration suddenly reached Yeojin’s ears.
“?!”
Sluuuuurp—!!
“Huuuuuuuuuuup!!!!”
A powerfully vibrating dildo thrust deep into her pussy without warning.
Whirrr~~~ Sluuurp!! Whirr, whirrr, sluuurp, sluuuurp~~
“Uuup!! Huuungup!!”
Naho began stirring Yeojin’s insides with the vibrator. The wild motion made the rotor already inside her tumble and grind, sending such intense stimulation through her that it felt like electricity crackling straight into her brain.
Yeojin, who had only just grown used to the earlier torment and found it bearable, nearly broke in a single instant.
“Huuuguuuuuuup!!!”
“Hehe. How does it feel? Rather nice, isn’t it? It’s good for a mother-in-law and daughter-in-law to bond like this once in a while.”
“Uuup!!! Huuuuup!!!”
Haaak!!! What kind of bonding is this?!
Yeojin wanted to reject the words, yet her body was already beginning to respond against her will. Little by little, she started to tremble.
Naho noticed the change in Yeojin’s condition immediately and began moving more aggressively.
Sluuuck! Sluuuuurp!! Chuuuuurp!!! Sluuuuurp!!!! Sluuuuuuurp!!!!!
“Haup!!!!! Huguguguuuup!!”
No…! It’s… dangerous… The stimulation is too… much… Haa…
Sluuuuck~
“!?!”
Just as Yeojin teetered on the edge of climax, Naho pulled the vibrator free and weakened the rotors once more.
Why…?
Naho explained why she had stopped short of letting Yeojin finish.
“If you cum too easily it would be unsatisfying for you too, Yeojin. There’s still plenty of time before Segyeong’s father returns. Until then, let’s enjoy ourselves… or rather, let’s do our best, shall we?”
Ah…
Yeojin understood.
Mother-in-law is exactly the same as Father…
She too wanted to toy with Yeojin’s body. Despair washed over her. The bet she had thought she might somehow endure had become nearly impossible to win the moment Naho joined the game.
Yet Yeojin refused to give up. She fought to hold on, because she did not want to lose to either Naho or Daegeun.
But regardless of her will, Naho proved to be every bit as formidable an opponent as Daegeun.
After that, Naho returned at carefully timed intervals—just as the lingering pleasure began to fade—slipping in and out of the room to torment her again and again.
Once she used the electric massager, rotor, vibrator, and love gel together, lavishing attention on Yeojin’s clitoris until she was on the brink, then stopping.
Another time she adjusted the speed of the anal beads, sliding them in and out repeatedly until Yeojin’s rear had grown just as sensitive. Thanks to the enema, the area was far more responsive than usual; Yeojin nearly climaxed from anal stimulation alone, but Naho stopped her yet again at the last second.
Again and again Naho brought her to the edge, stopping each time before release, carving unbearable torment—not pain—into every inch of Yeojin’s body.
When Naho entered the room once more, Yeojin could only manage a weak sound.
“Uuup….. Huuup….”
Stop… already…
She no longer even had the strength to complain inside her own mind. She had reached a state where climax could crash over her at any moment.
“How are you feeling, dear? It’s quite difficult, isn’t it?”
Naho began speaking to her.
“This is the most basic of basics. It feels manageable at first, but the longer it goes on the harder it becomes.”
“…..”
“However—”
Naho paused, then simultaneously assaulted Yeojin’s clitoris, pussy, and anus with powerful stimulation.
“Huuuup!!!!!!!!!”
Pssssssssssssssssssssssshhhhhh!!!!!!!!!!
Pffrrt..!! Pffrrruuurrrrrt!!! Pssshh-ssshhh!!! Splurt… Pffrrrt…. Pffrrruuurrrrrt!!!
The climax Yeojin had been desperately holding back exploded all at once. Her whole body shook violently. Saliva poured wildly from the corners of the gag.
At the peak of her orgasm, her fluids gushed out like a fountain, drenching the room. The anal beads that had sealed her rear shot out with the force of it.
The playroom was left soaked with Yeojin’s juices.
“Ohhh~ Magnificent. It’s been a long time since I’ve seen anyone cum so spectacularly!”
Naho gazed at Yeojin in open admiration, then stepped closer and removed the gag.
“Haa………”
Drip, drip, driiiiiip~~
The moment the gag came free, a large quantity of saliva that had pooled in her mouth spilled out.
Even without the gag, the utterly exhausted Yeojin could only moan; no words would come.
“Haa…. Haa… Haa… Haa…”
Click.
At that moment Daegeun entered the room.
“Oh? You’re back already? Has it been that long?”
“Yes. How did it go?”
Daegeun asked Naho about Yeojin’s condition while his eyes swept over the room.
“Ah~ I don’t even need to ask.”
The evidence of Yeojin’s spectacular orgasm was obvious to anyone who looked.
Daegeun approached her.
“It seems I’ve won the bet.”
“……”
Yeojin still had no strength left to answer.
Daegeun began removing the various devices attached to her body.
“Haah….!!! Haaang…..!! Aak….!”
Her body had grown so sensitive that even the slight stimulation of the toys being withdrawn drew reactions from her.
Once every rotor had been taken out, Daegeun spoke again.
“Let’s see. Shall I check for myself?”
“Eh?”
He slid a finger into her anus and began to stir.
Sluuuuurp~ Squuuuuurk~ Sluuuuuurk~ Sluuuuuuuuurk!!
Her rear, already thoroughly soaked, produced the same lewd, obscene sounds one might hear from a pussy. The heightened sensitivity sent Yeojin straight into another climax.
“Haah!!!! Father… stop…!!! Sto… haaah!!!!!!!!!!”
She was so overwhelmed by the sensation that she couldn’t even form proper words before she came again.
“Haguguguuuuuuuuk!!!!”
Psssssssh!!!! Psplurt!!
Even though she had climaxed moments earlier, she squirted once more.
Daegeun withdrew his drenched hand.
“Excellent. To become this sensitive in such a short time… It reminds me of you when you were young.”
“Really~ Saying such things in front of your wife is embarrassing~♥”
Daegeun looked thoroughly satisfied as he gazed at Yeojin. Together with Naho, he finally released the still-bound woman.
After hours of restraint, Yeojin’s body was finally free. But she had no strength left; she crumpled to the floor the moment she tried to stand.
Daegeun approached, stroked her hair, and spoke gently.
“You worked very hard today. Rest with what time remains.”
“……Yes……”
Her answer was faint and drained.
Daegeun lifted the exhausted Yeojin into a princess carry.
“Ah…! F-Father-in-law?!”
Yeojin startled.
“You’ve cum so much you can’t even stand. I’ll carry you to the bathroom. Wash up and rest. Your mother-in-law and I will take care of everything else.”
“B-but… like this…”
Though she had no energy, the situation filled her with embarrassment and made her heart race. No one had ever carried her like a princess before. Not even her husband Segyeong—and it would have been impossible for him anyway.
The fact that her first experience of this was with her father-in-law shocked her, and the way Daegeun’s solid frame lifted her so effortlessly made her pulse quicken even more.
As he carried her out of the room, Daegeun spoke to Naho.
“Sorry, honey. Could you clean up? I’ll be back as soon as I’ve seen her off.”
“Honestly… Fine…!”
Naho sounded a little sulky. The princess carry had clearly been the biggest offense.
Daegeun noticed at once. He leaned close and whispered in her ear.
“I’ll spoil you plenty later, so forgive me~♡”
Naho’s mood improved instantly.
“You’d better! You won’t be sleeping tonight~♥”
“Understood~”
Daegeun left the room and carried Yeojin carefully down to the first floor.
“You really worked hard. It must have been difficult.”
“….Yes… a little…”
Daegeun gave a bitter smile.
“It sounds strange coming from me, but… you’ll get used to it.”
When they reached the bathroom he set her down gently.
“Segyeong should be home from work soon. Wash up and rest in your room. We’ll prepare everything else.”
“Yes…. I’m sorry…”
“What are you sorry for? It’s all right. Take your time.”
“Yes…”
Daegeun headed straight upstairs.
Left alone, Yeojin turned on the warm water and stepped into the shower.
Shhhhhhhhhhhh~~ Shhhhhhhhhhhh~~
She stood with her head bowed beneath the spray, lost in thought.
Slowly she brought her hands to her breasts, then lower to her pussy.
Throb… throb…
“Haa…. It still feels… tingly all over…”
“Every time I’m with Father-in-law, my body seems to change…”
The afterglow of the day still lingered.
Moreover…
Her hand drifted from her pussy to her buttocks.
This place… felt good too…
“!!”
Yeojin flushed with shame at her own thoughts.
“What on earth am I thinking…!!”
She switched the water from warm to cold, trying to cool her heated mind.
What is happening to my body…?!
