Chapter 18
After showering, Lee Yeon-seo found herself blushing as she replayed the events of the previous night in her mind.
"Really... it doesn't make any sense, does it...?"
It wasn't just last night.
She had chosen to comfort her son-in-law, Kim Seok-hun, after her daughter Seul-ah had shattered his heart. It had started as a way to take responsibility for her daughter's actions by soothing him herself.
That relationship had changed the night she discovered traces of his masturbation.
"What on earth was I thinking back then...?"
She didn't know.
She had simply assumed he was still unable to forget Seul-ah.
But then there were all those files on his computer labeled [Mother-in-law].
While the AVs covered various concepts, every single one revolved around a mother-in-law.
Was that when it began?
"Maybe he really does see me as a woman," she had wondered.
A woman.
Yes, a woman.
The traces of his repeated masturbation over several days all pointed back to her.
In other words, he hadn't been thinking of Seul-ah while touching himself. He had been imagining her.
And that night.
She had heard it clearly.
The word "mother-in-law" had burst from his lips.
There was no doubt.
She was certain he desired her.
Normally, she should have left the house in that situation.
Yet why had she decided she needed to relieve that desire herself?
She didn't know.
She had simply wanted to.
While searching for a way, she had come across a video titled [Sleeping Mother-in-law...].
It was about a son-in-law penetrating his sleeping mother-in-law.
The moment she saw it, an idea had formed in her mind. And that idea had ultimately succeeded.
"Mouth... breasts... and finally, penetration."
It was embarrassing.
Even now, thinking about it made her feel incredibly ashamed.
But last night, the look on Seok-hun's face after crossing that final line had been one of genuine happiness.
He had truly enjoyed penetrating her while she slept.
"So I enjoyed it too..."
It was the truth.
Even though the relationship had begun because of Seul-ah, she had liked it.
Her son-in-law's thick shaft had filled her completely, and she had climaxed while drenched in his essence.
"How was it for him? Was I better than Seul-ah?"
If she only considered yesterday, it seemed likely she had been better, but there was nothing she could do about it.
She had to remain asleep and leave everything to his hands.
Men usually preferred women who took initiative.
Especially someone as sexually vigorous as Seok-hun might want a woman to do more and throw herself at him.
Yet that was impossible in her position.
So she was curious.
She was also a little afraid.
What if, after actually doing it, he found her inferior to Seul-ah?
She was approaching forty now.
Could someone like her possibly taste better than a daughter in her early twenties?
Could she have been better?
She didn't know.
It had been so long since she had sex with a man that she could barely remember.
How had she endured all this time?
She had been too busy raising two daughters to think about it.
If it weren't for them, she might not have been able to hold back and would have gone around meeting all sorts of men.
Seul-ah's current obsession with sex with men was probably because she took after her.
"Haa... even though he came..."
Even if Seok-hun had ejaculated, that could have happened with any woman, so she still couldn't be sure.
Just like that...
"Huh? When did this happen again...?"
While showering and imagining the previous night and all the moments that had led to it, she had unconsciously touched the cleft between her legs.
"Why is it so wet?"
It was far wetter than she had expected.
"I guess I need to wash again... Sha. Wer. Time."
In the end, Lee Yeon-seo turned the shower on once more and directed the head between her legs...
"Hnn...!!"
She washed herself.
* * * * * *
Kim Seok-hun opened his eyes more than three hours after Lee Yeon-seo had finished showering.
It was well past noon when he finally woke, emerging into the living room with a sleepy expression.
"Huh...? Mother-in-law? Did you sleep well?"
"Mm~ I slept great. How about you?"
"Ah... yes..."
"You must have worked out too hard yesterday. You slept for so long, Seok-hun."
"Did I? Ah... yeah, I guess so. I was trying to push myself since I was already at it, so I might have overdone it."
"Aigoo... take it easy. I already think you look perfect just the way you are."
"Hehehe, really? Still, if I'm going to open a gym someday, I need to learn properly."
"Hohohoho, are you taking the day off today?"
"Yeah, I think I should."
Lee Yeon-seo found even his disheveled appearance unbearably adorable.
Cute.
Knowing exactly what kind of "overdoing it" he had done yesterday, she could only see him as incredibly endearing.
Still, a small doubt lingered in her mind. Three times probably wasn't enough for him, was it?
The atmosphere between them as they faced each other again was warmer and more harmonious than the day before.
After showering, Seok-hun had come out to the living room wearing only his underwear. Lee Yeon-seo smiled naturally at the sight and warned him to be careful not to catch a cold.
Once he had showered and dressed, she asked,
"Seok-hun, want me to clean your ears?"
"My ears?"
"Yeah, should I?"
"They've been feeling itchy anyway. I'd really appreciate it."
"Ohohoho, really? Come here."
"Yes!"
Their relationship had softened once more.
Kim Seok-hun treated his mother-in-law more comfortably now,
and she treated her son-in-law even more at ease.
When Seok-hun sat down on the floor in front of the sofa, Lee Yeon-seo pulled him up.
"Not like that. You should lie down here. Use my lap as a pillow."
"Is that okay?"
"Of course. Whose son-in-law are you?"
"Yours, Mother-in-law. Haha, but don't complain if my head's too heavy, okay?"
"I won't. Now lie down."
Pat pat—
Lee Yeon-seo patted her thighs invitingly.
Slide—
Softly—
Kim Seok-hun gently rested his head on her thighs, careful not to put too much weight on her. She began slowly stroking his hair.
"Your hair is so nice, Seok-hun."
"Really? Nah... it's just short."
"No, it's really nice."
"Haha, thank you. Your hair feels like silk, Mother-in-law."
"Oh come on... hohoho, but it does feel nice to hear. Alright, let's begin."
"Okay."
Lying on the sofa with his head on her lap and facing the TV, Kim Seok-hun felt Lee Yeon-seo lean forward slightly to properly clean his ears.
In that moment!
Squish—!!
An overwhelming presence pressed against the back of his head.
As expected... they're really big. Feels nice though. Haha.
He didn't need to look to know.
That soft, heavy sensation could only be his mother-in-law's breasts.
He had touched them a few times already, so he knew them well.
Really... his mother-in-law's breasts were the absolute best.
"Haha, ah, this feels great. It tickles but it's refreshing too. You're really skilled at this."
"Oh my? Really? Hohoho, tell me if it hurts, okay?"
"Yes!!"
It had been a long time since he'd received such pleasant stimulation.
The ticklish sensation faded into something enjoyable, and he felt like humming.
"Now turn over. I'll do the other side."
"Huh? Ah... okay..."
Once his right ear was done, she told him to turn over for the other side... but...
If I turn like this... well, whatever.
She was only cleaning his ears. There was nothing more to it.
So he just closed his eyes and turned over.
Whoosh— rustle whoosh—!!
As Kim Seok-hun rolled over, he avoided turning his face upward and instead brushed against her thighs, causing her skirt to ride up slightly. Between her parted legs, her panties came into view.
Of course, Seok-hun couldn't see it, and since only the two of them were in the house, it didn't matter anyway.
Now lying on his back...
Ah... this really feels amazing.
The fullness enveloping his face and head made him feel more at peace than anywhere else in the world.
And that wasn't all.
Huuup... haa... it smells so good. I want to burrow deeper...
The scent coming from her stomach was incredibly pleasant.
He wanted to wrap his arms around her waist and press even closer, and if he turned his head a little lower, he could catch the scent from between her legs.
Desire surged up again, and Seok-hun, unable to control himself, grew erect while wrapping his arms around her waist.
Slide— squeeze—!
Hm?
Lee Yeon-seo was slightly surprised when her son-in-law hugged her waist, but she didn't stop him.
If he was just holding her, what was the problem?
Even when his face pressed deeper into her stomach, she didn't mind.
Our son-in-law... such a baby.
As he burrowed deeper, she adjusted the position of her breasts so he could press his face in more comfortably. She lifted one breast and draped it over his face while resting the other on top of his head.

His face sank even deeper into her softness. Because of that...
I can see it clearly now.
His ear canal was even more exposed.
As she resumed cleaning his ears, Seok-hun squirmed in pleasure, which made Lee Yeon-seo feel good as well.
Even after finishing both ears, she left him lying there for a while. Then...
"Seok... hun?"
Snore— snore— snore...
Kim Seok-hun had fallen asleep just like that.
"Oh my... did our son-in-law fall asleep? Hohoho."
She gently shifted his body so he could lie more comfortably on his back, and he continued sleeping soundly with his head on her lap.
"How adorable..."
Could a sleeping face really look this lovable?
It seemed impossible, yet he truly looked like a cute little angel.
Just then.
"Mmmph... mmmph..."
"Hm?"
His lips began twitching as if he were talking in his sleep. The problem was that they were curling inward, as though sucking on something.
"Oh my? Does our son-in-law want to suckle?"
Having breastfed before, Lee Yeon-seo understood exactly what those lips meant. Smiling softly, she exposed one breast and brought it to his mouth.
Slide— jiggle—!
Chomp—!!
"Suck suck, even if nothing comes out, our son-in-law drinks a lot."
The moment she placed her breast against his lips, he began sucking eagerly.
Slurp slurp slurp
Suck suck suck
Slurp slurp
"Hnn... he's so strong... haa... our son-in-law eats so well..."
Suck suck
Slurp slurp
"Haa..."
