Dominating MIL

"Aahhh♥…Uummmm♥"

"She's cute even when she's sleeping."

After our not-quite-sex session, Yeonji, exhausted, has fallen asleep first.

'Did her mom already hear that?'

Yeonji, unable to hold back, moaned loudly while rubbing her pussy lips against my dick.

Thanks to that, it was obvious that her mom, whose room shares the only thin wall with mine, would have heard it.

'It felt good, but… it's still not enough.'

After having sex with Yeonji, I still feel that same disappointing sense of inadequacy.

I've felt this disappointment before, but this time it feels even stronger.

Even after masturbating a few times in secret to relieve myself, it's like I haven't done anything at all, my desires are still unsatisfied.

'Is it because I've actually done it now?.....'

Maybe it was because I experienced real sex with her mom, but this emptiness feels even more profound.

Before, I could somewhat satisfy myself with pseudo-sex with Yeonji, but now, even though Yeonji was sound asleep, my dick was still hard and throbbing.

"Gulp…"

Next to me, Yeonji was sleeping soundly, her chest area bulging even under the blanket.

I know her body, hidden under the blanket, was seductively tempting, and it was even harder to resist.

'What should I do…?'

I feel an urge to pounce on Yeonji right now.

My dick was ordering me, and the desire to just pounce on the sleeping Yeonji was growing stronger.

'Should I just masturbate until it goes away… or maybe…'

Pouncing on Yeonji like this is out of the question.

Forcibly inserting myself into her pussy, which still can't accept my dick, while she's sleeping?

That would give her the worst first experience, and I can never do that.

And I have two choices left.

Masturbate… or go to my mother-in-law…

Even while I was agonizing over these two choices, my dick was throbbing and not dying down at all…

Swoosh…

I carefully approached the wall, making sure not to wake Yeonji.

Slide…

The wall opened quietly.

In the end, I couldn't forget the pleasure of real sex that my mother-in-law had shown me, and I left Yeonji behind and went into another room.

...

"M-Mother-In-Law?"

I carefully entered my mother-in-law's room and called out, but there was no answer.

I checked that Yeonji was asleep and closed the wall.

'Ah… she's sleeping.'

I came into my mother-in-law's room with the hope that she might be awake, but she seemed to be sleeping, lying on the bed.

"How can this body be that of a widow who's given birth… gulp"

Her mom was wearing only a thin black negligee.

It was all see-through mesh, so I could see her breasts and even her pussy.

"No matter how many times I see it… it's incredible."

My mother-in-law's body, which I saw first when we mixed bodies, was as young as the young Yeonji.

It was seductively tempting, as if it was trying to lure me.

'Should I pounce on her like this?… I think it would be okay with her …'

My relationship with her wasn't normal as we have a master-servant relationship, so in a way, I can do whatever I want with her body.

It could be considered fuck, but since she has submitted to me as my sex slave, I don't think she would hate it even if I pounced on her when she didn't want it.

'I think she would actually like it…'

Like the true masochist she was, she gets even more excited whenever I treat her roughly or insult her.

So, it was obvious that she would be happy even if I sleep fuck her.

"Should I do it..."

If it were the old me, I would have thought it was absolutely wrong and gone back to my room, but the strong urge that was slowly creeping out was making the brakes on my actions increasingly blurry.

Swoosh…

As I got closer and looked at her body, my dick throbbed.

It was screaming that it wanted to fuck the female in front of me right now.

"Gulp…"

Swoosh.....Grip

"Hmm…"

Unable to resist the urge, I reached out and grabbed her breast.

My hand was on the larger side, but her big breast didn't fit in one hand.

I squeezed it a little harder, distorting its shape and feeling its soft texture.

"Haa… haa…"

Her breast, which had a different softness than Yeonji's, made my hand move on its own…

Squeeze…

"Haaang♥"

"Ah!"

I squeezed her breast so hard that even I was surprised.

'D-Did she wake up?'

I squeezed her breast with enough force to wake her up, and I let go, but she didn't seem to wake up.

'Huh? Wait a minute… Could it be…?'

It was definitely hard enough to wake her up, but she didn't seem to wake up. I looked at her closely and noticed a change.

Her nipples were slowly getting erect.

They were clearly more erect and bigger inside her negligee than when I first saw them.

'She's awake!'

I can't be sure, but it looks like she was pretending to be asleep.

'Let's check… gulp'

With trembling hands, I slowly reached out to her thigh to confirm if she was really awake.

Twitch… Twitch…

Her body twitched slightly when my hand touched her thigh.

Swoosh…

"Heeung♥"

As my hand moved up little by little and her moan escaped then…

Squish…Knead…

"Haaang♥…"

Her pussy was already wet and ready, as if she had prepared for it.

'Is she pretending to be asleep because she wants to be fucked on purpose?!'

I can't be sure, but considering her tendencies, it was entirely possible.

She must have heard the sounds that Yeonji and I were making, and she might have even predicted that I would come here.

'If that's the case… I don't care!!'

It was different if she was pretending to be asleep, not actually asleep.

It was more like she wanted me to touch her and fuck her.

I can't hold back anymore either, so I confidently climb onto the bed…

Whack! Split!!

"Eep♥"

I grabbed her mom's legs and spread them apart.

Her pussy, which was already wet and glistening with just a slight touch, was wide open and waiting for me.

"Is your pussy wet even when you're sleeping?… You're such a slutty bitch."

Twitch… Twitch… Twitch… 

I insulted her on purpose, but she didn't wake up. Her pussy just twitched and seemed happy.

Her pussy juices were dripping down, staining the bed, but I didn't stop.

Squish… Squish… Squish… Squish…

"Heeup♥… Aahhh♥…. Aahh♥"

She was doing her best to keep the moans from escaping, but I didn't care. I just kept poking her pussy with my fingers.

"Is your pussy dripping like this because you want me to fuck you?"

She kept pretending to be asleep and didn't answer, but her pussy was gripping my finger and wouldn't let go.

"Are you wetting your pussy because you want to get fucked by your son-in-law even though your daughter is sleeping next door? You horny bitch!!"

"AAAaaahhhhhh♥♥♥"

The more I insulted her, the tighter her pussy became.

'I can't hold back anymore!'

I roughly flipped her body over.

I knew she was already awake, so I treated her even more roughly without hesitation, but she continued to pretend to be asleep.

"Hoo… you have such a vulgar ass, seducing your son-in-law!"

Slap!! Slap!!

"Heeeuuung♥♥"

A moan escaped when I slapped her big ass.

I slapped her hard enough to leave a red handprint, but she didn't seem like she was going to wake up.

Swoosh!

I grabbed her ass and pulled it up, putting her in a position where she was lying face down with only her ass raised.

"You slutty bitch."

Slap!! Slap!! Slap!! Slap!!

Slap!! Slap!! Slap!! Slap!!

"Heeup♥ Heeuh♥ Aahh♥"

She tried to hold back the sounds, but she couldn't help it as her pussy was being poked and finger-fucked.

The more she did, the more I wanted to torment her.

Slap!! Slap!! Slap!! Slap!!

"Yeonji is sleeping next door… You can't be too loud."

Thump…

"Heeup?!♥"

I pressed her head into the pillow to keep the sound from escaping, and then I inserted my dick into her pussy.

"Hoo… You're such an onahole pussy that bites my dick even while you're sleeping."

Twitch… Twitch… Twitch…

My dick went in smoothly, and her pussy immediately tightened and rejoiced.

'I almost cummed right away!'

Maybe it was because I felt so unsatisfied with Yeonji earlier, but her mom's pussy was so tight that I almost cummed right away.

Slap!! Slap!! Slap!! Slap!!

 Slap!! Slap!! Slap!! Slap!! 

"Ummmm ♥ Eubeueueueup♥"

Her voice was small because her face was buried in the pillow, but I could tell that she was so excited that she couldn't control her sounds.

"Your ass is so big that it makes a loud noise every time we bump!"

Thwack! Thwack! Thwack! Thwack!

"Heeeuuuungup♥"

The sound of my dick hitting her ass was louder than her moans.

Even if the walls were thin, it was not enough to be heard outside, but the sound was echoing in the room.

She must be able to hear how roughly she was being fucked right now.

"Because of your perverted pussy, I can't be satisfied with just smacking anymore!!"

Squish Thwack! Squish Thwack! Squish Thwack! Squish Thwack! Squish Thwack!

I spoke to her as if I was venting my anger, and I felt a strong sense of conquest that I was so angry that I poured everything out.

"What if I can't forget your perverted pussy even when I have sex with Yeonji later!"

Squish Thwack! Squish Thwack! Squish Thwack! Squish Thwack! Squish Thwack!

"What am I supposed to do if I want to keep using this sow's pussy even after I have sex with Yeonji, get married, and have kids!!"

I know that my relationship with her will have to end someday, but it seems like I've already crossed an irreversible line.

I've completely fallen for her slutty body.

"From now on, I'm going to fuck you whenever I want, no matter if you're my mother-in-law or not!!"

Thump…Slap!! Slap!!

"Aahhh!!"

Brrrrt Brrrrt Brrrrt Brrrrt

Instead of answering with her mouth, she answered me by tightening her pussy around my dick.

I answered in kind, and I cummed inside her pussy, filling it with white.

"Haa… haa… haa…"

After a long orgasm that seemed to have poured everything out, I pulled my dick out of her pussy and quietly went back to my room.

Leaving her behind toward her daughter…
