The Secret Guest
"Th-this is... *gulp*♥......... *Haa*♥..... *Haa*♥...... *Haa*♥......"
Yeonhee, who was secretly peeking, couldn't tear her eyes away from the impossibly lewd scene unfolding before her.
"Oppa♥.... You're the best♥..... Your cock is♥....."
Yeonji was being handled in a vulgar display, held up as if she were nothing more than a tool for a man to use for his own pleasure.
It was more than just sex; it was a scene of overwhelming power and stamina, where she was pinned down, unable to escape, and used exactly as the man desired.
'She looks happy...'
Yet, despite being captured and unable to resist, Yeonji’s face was filled with a smile, as if she were truly happy.
Yeonhee had known Yeonji for a long time and prided herself on knowing everything about her, but this was a look she had never seen before.
She was no longer a woman, but a mere female, soaked in pleasure and wearing a lascivious smile as she took the man's semen into her own pussy.
"*Haa*♥..... *Haa*♥.... *Haa*♥...."
*Squelch, squelch, squelch.*
A cock so large it felt dangerous was buried deep inside Yeonji’s small pussy, thrusting with such force it looked as if he were trying to pierce her womb.
He was thrusting so violently that every time he drove in, Yeonji’s belly would bulge slightly, making Yeonhee fear for her safety, but...
'Ar-are you really enjoying this, Yeonji?'
Yeonji never once made a sound of pain or distress; she only let out animalistic moans, as if she were completely drowned in pleasure.
"Wh-what am I doing right now..."
At first, she hadn't been able to look away from the lewd sight, intending to intervene if she felt Yeonji was in danger.
But she felt no such thing from Yeonji; she only saw a lewd female, drenched in pleasure.
Because of that, feeling her own body heat up, she reached into her panties and began to masturbate, watching the affair between Yeonji and... her younger sister's lover.
"Yeonji, are you okay? Hmm?"
Juhyun, who had been using Yeonji like a masturbation sleeve just moments ago, spoke to her with a concerned tone now that he was finished.
"Ooh♥....... *Hnnng*♥... *Hee-uh*♥"
But Yeonji, as if she had already lost her mind, only let out foolish, incoherent sounds.
'Wh-what do I do? I should go in and help the young lady... but then she'd know I was peeking... but the young lady looks so happy...'
The fact that she had been fucked to the point of fainting meant she was physically at her limit, so she felt she should help, but Yeonji’s face was full of smiles, as if she didn't need any such help.
"*Ugh*♥.... M-my panties are like this...."
She hadn't been paying attention to herself while focusing on Yeonji, but Yeonhee’s own panties were now soaked through from her masturbation.
'Yeonji is fine, so I should just leave here...'
Having forgotten the original purpose of her visit and becoming a voyeur of someone else's sex, Yeonhee tried to hurry away, but...
*Squelch.*
*Glug, glug, glug.*
"Did I cum too much?"
"*Gulp*♥"
As he pulled his cock out of Yeonji’s pussy, her gaze was once again captured by Juhyun’s cock and the semen flowing out of her.
'Th-that something so big went inside her♥...... And is semen supposed to come out that much!?♥'
Yeonhee was struck with astonishment at the thick, slow-flowing semen, but at the same time, she couldn't tear her eyes away, completely enthralled by the cock and the fluid.
"Hmm..... I guess this won't do."
After pondering for a moment, Juhyun carefully laid Yeonji down on the floor and began to wash her off simply.
"*Haa*♥.... *Haa*♥... *Haa*♥..."
*Squelch, squelch, squelch.*
In the end, Yeonhee didn't leave right away, watching Juhyun and Yeonji until the very last moment before finally regaining her senses, quietly slipping out of the room, and returning to her own.
"Yeonji got there before me...... *Haa*......"
She felt a strange sense of being left behind as a woman compared to her younger sister, yet the scene refused to leave her mind.
"Doing that to Yeonji.... *Ugh*♥"
*Squelch, squelch, squelch.*
Before she could even think, her hand naturally drifted down to her crotch.
"Something that big, inside Yeonji♥... *Hnnng*♥"
She knew how pathetic and foolish it was to be aroused by watching her sister have sex with her boyfriend, but the intense, irresistible arousal forced her to completely forget her original purpose, and Yeonhee spent the entire night pleasuring herself to calm her heated body.
"*Whew*..... I think that's enough for now......"
"*Snore*........."
After the rough sex in the bathroom, I washed her off and laid her on the bed.
"Oppa♥....... *Mmm*...."
Yeonji, completely exhausted and having fallen asleep after fainting, showed no signs of waking up, so I moved her as she was and laid her on my bed.
"What do I do about this....."
I hadn't expected Yeonji to faint in one go, so it was a bit of a confusing situation.
The urge to fuck her again while she was unconscious in the bathroom welled up, but I managed to calm myself down since I couldn't do that.
"*Haa*..... Can't be helped.... I'll just have to sleep like this..."
Honestly, I felt like doing it two or three more times, but even if I woke her up to do it, her body wouldn't be able to handle it.
Since Yeonji wasn't very strong physically or stamina-wise, rough sex where I just vented my desires would be quite a strain on her.
'I'll have to learn how to pace myself from now on...'
Since my first experience was with my mother-in-law, who accepted all of my dark desires, I never learned how to control myself properly.
"If I keep doing this with Yeonji...... it's going to be tough."
Because Yeonji wasn't used to accepting pleasure yet and had a low threshold, I couldn't just have rough sex.
"That aside, what did my mother-in-law put in that abalone porridge?.... I was so exhausted this morning I couldn't even get a hard-on... but now I'm completely fine..."
To be precise, the abalone itself was raised specifically to aid in stamina recovery, and each one cost hundreds of thousands of won, but I had no way of knowing that.
For reference, the abalone porridge I ate this morning would cost about 2 million won if converted to currency.
That was why my stamina and virility had recovered so quickly; I actually felt better than usual.
Because of that, even now, I wasn't satisfied and was still standing tall, but since I couldn't continue, I had no choice but to lie down next to Yeonji and prepare to sleep.
'Come to think of it, I felt like someone was watching us the whole time..... A ghost?..... No way.'
It wouldn't be strange for a ghost or two to live in such a massive mansion, but it gave me the creeps.
"Must be my imagination....."
No matter how I thought about it, the idea of a ghost appearing to peek at us having sex seemed unlikely, so I lay in bed, feeling unsatisfied.
"She's pretty...."
Seeing Yeonji asleep without a care in the world, a smile naturally spread across my face.
She had such a pure face, it was hard to believe she was the same female who had been making lewd smiles at my cock and rejoicing while being fucked roughly just moments ago.
"Should I get some sleep too....."
I had a date with Yeonji tomorrow, so I couldn't stay up too late. Pushing aside my lingering desire, I closed my eyes to sleep.
'But I feel like I forgot something...'
As sleep slowly crept in, I felt like I had forgotten something, but I couldn't put my finger on it.
'Well, it can't be anything important....'
Unable to overcome my drowsiness, I decided to let it go and drifted off to sleep without remembering.
30 minutes later.........
*Creak.....*
"*Hnnng*..... You seem to have completely forgotten..... Master♥"
The secret door in the wall opened, and my mother-in-law entered quietly, lost in thought as she watched Juhyun sleeping with Yeonji.
"It seems that a Master who fails to keep his promise..... needs a little punishment♥"
And with a smile as lewd as Yeonji’s in the bathroom, she slowly approached the sleeping Yeonji and Juhyun.
'Hmm...... What is this? It feels familiar.....'
"*Hnnng*♥ *Slurp*♥ *Mmm*♥ *Haa*♥"
At the pleasant sensation felt on my cock, I slowly began to regain consciousness without realizing it.
Perhaps because it hadn't been long since I fell asleep, my mind woke up easily.
'Is Yeonji sucking it?........'
If it were Yeonji, who was sleeping next to me, it wouldn't be strange if she woke up in the middle of the night to suck my cock.
As her lewdness continued to grow, it wasn't an unusual situation for her to wake up in her sleep and start sucking.
So, without much thought, I decided to enjoy it and placed my hand on the head of the person sucking my cock.
"Suck deeper, Yeonji....."
*Twitch.*
"*Hnnng*♥ *Slurp*♥ *Mmm*♥ *Haa*♥"
When I called her name, she paused for a moment, but soon she began to suck even deeper, using her throat, and I felt a pleasant rush of pleasure.
'She's good at this....... She's like my mother-in-law.....'
Considering Yeonji had struggled just sucking the glans in the bathroom, it was strange how easily she was using her throat to suck my cock now.
Moreover, her tongue was skillful, accurately targeting the spots I liked; her technique was considerable.
'Did she get this good in just a few hours?..... I don't know what it is, but it's not bad.'
"You're doing great..... *Mmm*...."
*Pat, pat.*
"*Hnnng*♥ *Slurp*♥ *Mmm*♥ *Haa*♥ *Slurp*♥"
When I praised her and stroked her hair, she seemed happy and began to suck my cock even more diligently.
"*Mmm*..... Good...... Yeonji, your mouth-pussy has gotten a lot better?...."
I was still half-asleep, but as my mind cleared from the vivid sensation of my cock being sucked, I slowly opened my eyes.
"*Mmm*...... Yeonji...."
Looking to my side through blurry vision, I saw the face of Yeonji, who was fast asleep.
'She's sleeping well......... She's sucking well with her mouth while sleeping well................................ Huh?'
"*Hnnng*♥ *Slurp*♥ *Slurp*♥ *Haa*♥"
I could still feel the sensation and sound of my cock being sucked, but Yeonji was fast asleep right next to me.
'No way.....'
And with trembling hands, I lifted the blanket slightly to look inside.....
"*Mmm*♥ *Slurp*♥"
I saw my mother-in-law, diligently sucking my cock with it held firmly in her mouth.
