[POV Change]
"Th-this is… gulp♥...…Haa♥…..Haa♥...Haa♥….."
Yeonhee, secretly peeking, couldn't tear her eyes away from the unbelievably lewd scene unfolding before her.
"Oppa♥….Aahh♥…..Suck it♥….."
It sounded as if Yeonji had become nothing more than a tool for a man's pleasure, used in a vulgar manner while held captive.
It wasn't just sex… It was an overwhelming difference in power and stamina, with Yeonji unable to escape, simply being used as an onahole.
'She looks happy…'
Yet, despite being captured and unable to resist, Yeonji's face was filled with a joyful smile.
Yeonhee, who had known Yeonji for a long time and prided herself on knowing everything about her, was seeing a side of Yeonji she had never witnessed before.
Not as a woman, but as a mere female, she was soaked in pleasure, wearing a wanton smile as she received the man's semen into her pussy.
"Haa♥…..Haa♥….Haa♥…."
Squish...Squish...Squish...
A dangerously large cock entered Yeonji's small pussy, pounding so hard it seemed like it would pierce her womb. With each thrust, Yeonji's belly slightly swelled, making it seem dangerous…
'Is… is it really okay for her to do that, Yeonji?'
Yeonji didn't make a single sound of pain or distress, only animalistic moans of pleasure.
"What… what am I doing…?"
At first, she couldn't take her eyes off the lewd scene, but if she felt Yeonji was in danger, she was ready to intervene.
However, Yeonji showed no signs of distress, only the image of a lewd female soaked in pleasure.
So, without realizing it, she felt her own body heat up, and she slipped her hand into her panties, masturbating as she watched Yeonji's… lewd intercourse.
"Yeonji, are you okay? Huh?"
Juhyun, who had just been using Yeonji like an onahole, spoke with concern as he finished.
"Ooh♥....Heuh♥…Heh♥"
But Yeonji, as if she had lost her mind, only made foolish noises.
'Wh.. what should I do? I should go in and help the young lady… But then she'll find out I was watching… But the young lady seems happy…'
Being violated to the point of fainting meant she was already at her physical limit, so she felt she should help.
But Yeonji's expression was full of smiles, as if she didn't need any help.
"Ugh♥….My.. my pussy is like this…"
She had been so focused on Yeonji that she hadn't paid attention to herself, but now Yeonhee's panties were soaked from masturbation.
'Miss Yeonji is okay, so I should get out of here…'
Having forgotten her original purpose for being there, Yeonhee, who had become a voyeur of someone else's sex, tried to escape quickly, but…
Swoosh….
Gurgle…
"Did I cum too much?"
"Gulp...♥"
As Juhyun pulled his cock out of Yeonji's pussy, the sight of his cock and the flowing semen caught her attention again.
'Th... that big thing went in there♥...And is semen supposed to come out that much!?♥'
Yeonhee was shocked by the thick, slowly flowing semen, but at the same time, she couldn't take her eyes off his cock and cum.
"Hmm… this won't do."
After pondering for a moment, Juhyun carefully laid Yeonji on the floor and began to wash her simply.
"Haa♥….Haa♥…Haa♥…"
Squish...Squish...Squish...
Yeonhee didn't leave her spot, watching Juhyun and Yeonji until the very last moment, barely regaining her senses before quietly leaving the room and returning to her own.
"Yeonji before me… Haa…"
She felt a little behind her younger sister as a woman, but at the same time, she couldn't forget the scene.
"Yeonji likes that… Ugh♥"
Squish...Squish...Squish...
Before she could even think, her hand naturally went down below.
"That big thing inside Yeonji♥…Heuh♥"
She knew how pathetic and foolish it was to be aroused by watching her younger sister and her boyfriend have sex, but she couldn't resist the intense excitement. In the end, she completely forgot her purpose and spent the night comforting herself to calm her heated body.

[MC POV]
"Whew… I think that's done for now…"
"Aahhh...…"
After washing Yeonji, who had fainted after rough sex in the bathroom, he laid her on the bed.
"Oppa♥....Mmm…."
Completely exhausted, Yeonji, who had fallen asleep after fainting, showed no signs of waking up, so he moved her to his bed.
"What should I do…"
He hadn't expected Yeonji to faint so quickly, so he was a bit flustered.
He had been tempted to fuck Yeonji again while she was unconscious in the bathroom, but he managed to calm himself.
"Haa… I guess I'll just have to sleep like this…"
Honestly, he felt like doing it two or three more times, but even if he woke Yeonji up, her body wouldn't be able to handle it.
Yeonji wasn't physically or mentally strong, so rough sex that unleashed his desires would be too much for her.
'I need to learn how to control myself…'
Since his first experience was with his mother-in-law, who accepted all his dark desires, he hadn't learned how to control himself properly.
"If I keep doing this with Yeonji… it'll be tough."
Yeonji wasn't used to accepting pleasure yet, and her limits were low, so he couldn't just have rough sex with her.
"Anyway, what did my mother-in-law put in that abalone porridge?… I was so tired this morning I couldn't even stand, but now I'm completely fine…"
To be precise, the abalone itself was specially grown to enhance stamina, costing hundreds of thousands of won each, but he had no idea.
For reference, the abalone porridge he had for breakfast was worth about 2 million won.
That was why his stamina and energy recovered so quickly, and he felt even better than usual.
That was why he was still not satisfied and his cock was still hard, but he couldn't continue, so he 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 me… a ghost maybe?… No way??'
In such a large mansion, it wouldn't be strange to have a ghost or two, but he felt a little eerie.
"It must be my imagination…"
Even so, he wondered if a ghost would come out and watch them have sex; feeling regretful that he couldn't fully release himself, he lay down on the bed.
"She's so pretty…"
Looking at Yeonji, who was sleeping without knowing anything, a smile naturally appeared on his face.
It was hard to believe that she was the same female who had been smiling lewdly while looking at his cock and enjoying being roughly sex, now with such an innocent face.
"I guess I should sleep soon too…"
He had a date with Yeonji tomorrow, so he couldn't sleep too late. With a little regret, he closed his eyes to sleep.
'But I feel like I'm forgetting something…'
As sleepiness washed over him, he felt like he had forgotten something, but he couldn't remember what it was.
'It's probably nothing important…'
In the end, he couldn't resist the sleepiness and decided to let it go, falling asleep without remembering.
30 minutes later…
Click…
"Hehe… You seems to have completely forgotten about me… Master♥"
A secret door in the wall opened, and his mother-in-law quietly entered, looking at Juhyun sleeping with Yeonji, lost in thought.
"It seems like the master who didn't keep his promise needs a little punishment.♥"
And with a lewd smile no less than Yeonji's in the bathroom, she slowly approached Yeonji and Juhyun, who were sleeping.
.................
'Hmm… what is this? It feels familiar…'
"Haup♥ Chomp♥ Slurp♥ Slurp♥"
The pleasant sensation from his cock made him slowly start to wake up.
He hadn't been asleep for long, so he woke up easily.
'Is Yeonji sucking my dick?'
If it was Yeonji, who was sleeping next to him, it wouldn't be strange for her to wake up in the middle of the night and suck his cock.
As her lewdness was growing, it wouldn't be strange for her to wake up and suck his cock, so he decided to enjoy it without thinking much. He placed his hand on her head as she sucked his cock.
"Suck it deeper, Yeonji…"
Twitch… Twitch…
"Slurp♥ Chomp♥ Slurp♥ Slurp♥"
At his words, she paused for a moment but soon began to suck even deeper, using her throat, and he felt a pleasant sensation.
'She's good… She's like my mother-in-law…'
Yeonji had struggled to suck just the head of his cock in the bathroom, but now she was easily using her throat to suck his cock.
Moreover, she was skillfully using her tongue, accurately targeting the parts he liked.
'Did she get this good in just a few hours?… I don't know, but it's not bad.'
"You're doing well… um…"
Pat… Pat… Pat…
"Slurp♥ Chomp♥ Slurp♥ Slurp♥ Chomp♥"
He praised her and stroked her head, and she seemed happy, sucking his cock even harder.
"Um… good… Yeonji's mouth-pussy has gotten much better?…"
He was still half-asleep, but the vivid sensation of his cock being sucked made him gradually clear his mind, and he slowly opened his eyes.
"Um… Yeonji…??"
In his blurry vision, he saw Yeonji's face, sleeping soundly next to him.
'She's sleeping soundly… sucking well while sleeping… Huh?'
"Slurp♥ Chomp♥ Chomp♥ Slurp♥"
The sound and sensation of his cock being sucked were still there, but Yeonji was sleeping soundly next to him.
'Could it be…??'
And with a trembling hand, he slightly lifted the blanket and looked inside…
"Slurp♥ Lick♥"
He saw his mother-in-law, with his cock in her mouth, sucking it diligently.
