Enjoy!!

I applied those cards to be cautious so that the sound wouldn't leak outside and wake my family up.

When I saw my sister-in-law walking lightly, blood rushed to my dick.

It's not the first time I've seen my girls wearing sexy lingerie like that, but even though it's the same style, it's ultimately different underwear, and each woman feels different, so it was new every time.

It's always a joy to the eyes.

What my sister-in-law is wearing right now has thin straps that come down from her shoulders.

Baby doll lingerie serves as a bra substitute, slightly supports the breasts, and has a deep cut in the center that allows the bottom of the breasts to be slightly visible.

The flowy lace hem, which felt like a one-piece dress, barely covered the pussy.

In addition, the chest area was made of mesh with mixed patterns, and the nipples were visible and soft, which was very sexy. Except for her breasts, the inside was completely transparent, exposing my sister-in-law's smooth waist, belly button, and sexy black lace panties.

And those slightly fleshy thighs and pretty legs were coming towards me, step by step.

To prepare for this, I had made Seol sleep against the wall in the first place. I lowered her legs and sat on the bed, opening my arms to her.

Then my sister-in-law wrapped her arms around my neck, sat on my lap, and placed her forehead against mine.

"Seonha, am I sexy?"

"You are so DAMN SEXY. Did you buy it just to show me?"

"For a moment... your voice was too loud."

"I said it's okay. If Seol drinks that much and goes to sleep, she won't be able to wake up even if I scream three high notes here."

"Then I'm glad... Of course, I bought this to show you. You don't even know I have something like this, right?"

"It really suits you. Especially the glimpse of my sister-in-law's nipples... Wow… Sexy…!"

"Ah yes… ♡ Really, you're such a baby until you put your dick in my pussy."

A faint smell, as if she had even sprayed perfume, filled my nose, and I couldn't resist the temptation of the cleavage that was exactly at the same level as my face, so I made a move.

I felt the warm and soft texture of her breasts, took a deep breath, and smelled my sister-in-law's scent.

Swoosh, swoosh…

My sister-in-law affectionately hugged my head and stroked it.

Then, as if looking at Seol, who was sleeping behind me, she let out a little laugh.

"Her boyfriend is losing his mind over another woman's breasts, and she's sleeping soundly."

It's a voice filled with a sense of superiority, and it seems as if she's slightly looking down on Seol.

Perhaps because she wants to take care of her pride as a woman, she continues to speak out loud as if she wants everyone to hear.

"It looked like you were having sex just a moment ago, but it ended really quickly? I guess that her pretty body isn't enough to satisfy my Seonha dick."

Listening to that, I finally began to understand why she was standing alone in the kitchen when I came home earlier.

It was clear that my sister-in-law had an inferiority complex compared to Seol's perfection.

It's just cute to me and Seol.

"Well, my master actually likes me. He's fucking me at your place, so I can't help it."

There, my sister-in-law let go of her head and made eye contact with me.

And.

"Is that right, Seonha?"

To my sister-in-law, who asks with earnestness, as if asking me to agree with what she says or to fill her self-esteem.

"That's right. To me… my sister-in-law slut pussy has been my favorite since long ago."

I told her what she wanted to hear. At the same time, my sister-in-law's face brightened, and her bright smile gradually turned into a naughty one, and she started pulling up my t-shirt.

Sleuk

I calmly raised my hand in response, groped my exposed upper body as if my sister-in-law were tickling it, and exhaled hot breath.

"Ha… Really… I really want to know what to do with my master, who has a really nice body. A cute face... And is good at sex…♡"

To the words she murmured as she ran her fingers down the nape of my neck, collarbone, chest, and nipples, I responded by stroking my sister-in-law's soft tits under the lingerie.

"What should I do? You're mine, and I'm yours. We just need to love each other."

"Seonha… ♡"

Knead… Kuuk… ♡

"Aahhhh♡ If you touch my butt and press something like that, I can't…"

"No. I love you and want to touch you."

"Then that's okay."

It's easy.

Watching her brother-in-law rub her ass and fingering pussy she cummed lightly.

"Should we do it now? I feel like the sex I have with Seol isn't enough. But just doing this with my sister-in-law makes me so excited that I'm going crazy."

"Yes… Let's do it quickly. I think your sister-in-law is going crazy because she wants to be held by you.

"sister-in-law"

"Seonha… Kiss… Kiss… ♡"

My sister-in-law's lips overlap again.

Softly at first.

But gradually.

"Squeak… ! Aahhh… tsk… Haa… Aahhhhh… ♡ Kiss…!"

Intensely, giving in to lust, we started biting and sucking each other's lips as if we were going to eat each other up.

Sreuk!

My sister-in-law roughly took off my pants, and I roughly took off my sister-in-law panties and lingerie.

It was a pretty nice outfit, but as long as my body was on fire, it was only a hindrance. If it had been a garter belt or stockings, I would have left it alone.

Anyway, my naked sister-in-law sat on my lap and continued to kiss me, caressing my cock. I did the same, only moving her face and kissing her, teasing my sister-in-law's pussycat with my hands.

Squeak, squeak, squeak...

"Huh… Kiss♡ Aahhhh… Ehhh… ♡"

I touched the pussy hole to make the already wet pussy even wetter as we were sticking out our tongues and clashing with each other while smiling playfully.

It heated up in an instant, in a heated atmosphere.

I lay down on the bed first.

Right next to Seol, who was probably really asleep, and on top of me while I was lying down, my sister-in-law was on top of me, showing off the body of a woman in her prime despite being married.

She swept her dark brown hair back, exposing her firm breasts and erect nipples.

"What do you think?"

"I want to suck it."

"Ugh, pervert, pervert. I'll let you suck it later ♡"

Every time we meet, she deliberately shows me her clean armpits, which she washed.

My sister-in-law, who I only knew as my older brother, is now naked and making sex appeal to me like a lover.

She doesn't have a perfect body because she has a bit of flab, but her plainness gives her a subtle charm.

My sister-in-law showed me around her body as if she were so proud, and then she grabbed my dick and aimed it at her own pussyhole.

Chifuuuuuk… ♡

"Oooook… ♡ Aaaahhhhhhhhhh… Finally… Seonha's dick… ♡"

She accepted it as is and showed her face, melting with pleasure.

"Wow, it seems like your pussy is tighter than before? How did you relieve it while I was gone?"

"Ugh… ♡ That's right… We had phone sex sometimes. And you sent me a picture of your dick. And I masturbated while watching it. Ahhh♡… ♡"

"You said you didn't do it with my brother, right?"

"Of course… I didn't, you idiot… ♡"

"I'm sorry. I made you feel lonely."

"No… No. Do everything now, right now. You just have to do a lot now… ♡"

Jjigeeueuuk, jjigeuuuuut!

"Haa… ♡ First of all, I'll do it first."

Slap!! Slap!! SlaP!!...

"Ugh, yes♡ Aang… ♡ Aahhhhh♡"

Standing with her used pussy clamped around my dick, my sister-in-law lifted her arms up and shook her hips as if she were twerking.

She must have thought I had an armpit fetish, so she persistently showed me that area, keeping her pussyfoot, buttocks, and thighs pressed against my pubic bone.

And in those movements of the waist while shaking the breasts….

Jippueook, jjippeook, chipoop… ♡

"Ah, Seonha, I'm much better than your girlfriend, right?"

She was still secretly conscious of Seol and kept saying things that wanted to compare her. Well, I guess I started to feel that all women are the same.

"Yes, you are the best" I answered, massaging my sister-in-law's breasts with both hands and stroking her stomach and waist once in a while.

"It's just different from the pussy. I feel like I'm going to cum already."

"It's too fast."

"It's even weirder that my sister-in-law is shaking her hips on top of me like that and not cumming. And isn't it the same for you?"

Squeak… Kuuk… ♡

Aahhhhh… !

"Ahhhhh♡"

"Look, the love juice keeps flowing. Are you really feeling it?"

"Aaahhhh, suddenly, clit... It's against the rules... ♡ Ah♡ Your dick is so big and feels so good. How can I not feel it… ♡"

"Me too. My sister-in-law pussy is this good, so how can I not cum?"

"I can't help it… ♡ Come on, I'll put you in a good mood♡"

Yuna changed her comfortable sitting position with her body weight up to a squatting position with her knees raised.

And with your hand on my chest….

Jjigeuk… Slap… Slap! Phut! Slap… ! Cheolpuk… Slap!"

"Aaah… ! Ahh… ! Ugh, ahhh… ♡ Ah, ah!"

She started to fuck my dick vigorously, trying to hold back, but the uncontrollable moans echoed throughout the room.

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

"Aahhhh … ♡ Cum inside… Ah, ahhh! Inside my pussy..."

Her short hair touched her shoulders, and her sweaty breasts were shaking at the same time.

Her movement suddenly became more intense, and I, who was already feeling a sense of ejaculation, soon.

Burrrrut… ! Pusssst!

I gave my sister-in-law pussy a shot of something thick inside.

"Ugh… ♡ Haaaaa… ♡ I'm happy… ♡"

At the same time, my sister-in-law was so ecstatic that she had an orgasm with a face that looked like she was on drugs.

Pushuuut…

Her pussy juice, like urine, poured out onto my pubic bone.

At the same time, I held my sister-in-law's body, which naturally fell on top of me affectionately.

Pat, pat…

I patted my sister-in-law's plump buttocks as if she had done well.

" sister-in-law."

"Hmm… ♡ What?"

"Shall we kiss one more time? My sister-in-law, can you shake your hips like this again?"

"I can do it."

"Aaaaahhhh… Seonha breed me ♡"

"Wow, rubbing it inside with my cum... Ugh… "

"Kiss… Jooooopp… Kiss, Kiss… ♡"

I ejaculated once, but of course my dick was still hard.

Instead of taking it out, I kept fucking her pussy, and while holding my face, my sister kissed me, pressing her lips to the side as if showing off to Seol.

At the same time, although it is a bit difficult, lower her ass up and down again.

Slap… Slap… Cheolpuk… Slap… !

"Huh, huh… ♡ Aahhhh… ♡ Hee… ♡"

As she put my lips together and stuck out my tongue, a moan escaped her teeth.

As our love affair continued, our bodies began to get even wetter with sweat, and my sister-in-law and I became more and more excited by the strange wetness and heat.

In this position.

We were enjoying sex, kissing each other with so much saliva that it was almost dirty, and enjoying the thick kisses and caresses of my sister-in-law, who was sucking my lips and tongue.

I put another cream pie inside my sister-in-law's pussy.

Then I changed my position, and this time I laid my sister-in-law down on her bed and started having sex on top of her.

Then her loud moan came out suddenly.

"Aaahhhh.AAAAHHHHHHHH"

Slap, creak, SLAP, creak, SLAP, SLAP!

"Aahhhh…. Aahhh ♡ what if she wakes up. Ahheung♡ What should I do if Seol sees my face?"

In response to my sister-in-law's unexpected words, I asked back while moving my waist.

"Your face? She will probably be jealous because you are taking my dick?"

Crack, creak, slap, slap...

"That's… Huh, huh… ♡ Huh… ♡

As expected, the top position was at a top sex pleasure level.

The woman spreads her legs in front of me, and I look down at her as I plunge my cock into her clearly exposed pussy.

I can connect with women, and I definitely feel like I am fucking the women I like. I guess that's the case.

While I was thinking about random things for a moment, my sister-in-law continued her words in a gasping voice.

Aahhhh… Aahhhhh!

"You, Seonha… Huh, while you're having sex with me... Huh… Your face looks happier. Than when you're having sex with me... Ok,…. Aahhh… do you feel good♡"

"Oh…Yes sister-in-law pussy is good."

"Aahhhhhh…. hee… Right… Then fuck me harder♡"

It was a pretty interesting opinion.

And the moment I heard that, I realized that this also applies in the opposite situation.

I felt my cock rapidly becoming excited by the thought that came to my mind.

I bent down to the side and picked up my sister-in-law's panties that were lying next to the bed.

Sexy panties wet with love juice.

"Take this."

"Why… Aww… ♡"

I crumpled it into my sister-in-law's mouth, who was moaning endlessly, and positioned myself properly.

And.

Jjigeeook… ! Creak, Slap, Slap, Slap!!!!

"Oooooh… ♡ Ok, ohhhhh… ♡ Hikeuuuuu…!"

"Sister-in-law, I'm cumming!"

Burrrr! Bururrrrut!

I grabbed my sister-in-law's thighs and violently thrust my dick into her pussy, sending out another shot of cum.

"Huh… Heh… ♡"

I said this to my sister-in-law, who was spitting pants out of her mouth as she struggled to even scream out loud.

" sister-in-law. Let's change seats."

"Beeup… Where… ?

"Where? It's my sister-in-law's room."

"My, my room?! Your brother is there.

"Don't I have to show you in front of your brother? Who do you truly belong to? Who owns you?!!"

"Aaaahhhhh… ♡"

Jjigeeoeoeoook… Wow…

I have already pulled out a cock from her that has been loaded with 'fertile semen' three times.

Then, after raising her body, I grabbed my sister-in-law's arm and pulled her.

My sister-in-law hesitated, flinching at my hesitation in my actions.

"Are we really going?"

"Yes, we are really going."

"But… "

"Come quickly."

Even though she was surprised, embarrassed, and scared of getting caught when she saw that I was actually trying to put into practice, not just talk,.

Her face showed slight excitement and joy, and she followed my touch as if she had no choice.

Sweet!

And we eventually came in.

"Uhm… "

In the bed right in front of me, my brother was sleeping like a hangover.

In the couple's room shared by my brother and sister-in-law, I was going to have sex.
