Chapter 81 – [Short Story] I Witnessed My Handsome and Wealthy Brother-in-Law Fucking His Mother-in-Law… (7)
“Do you think you get excited thinking about your mom? Your dick gets harder.”
As my sister said that, she wrapped her slender legs around my brother-in-law’s body.
“Isn’t it the same for you?”
My brother-in-law did not give up and said that as he placed one hand between his sister’s legs.
“Are you really wet? Do you really want to see your mom getting fucked?”
“It’s nice to see my brother excited.”
My sister said that in a nasal voice and twisted her body.
“Come up and see.”
When the brother-in-law said that, the sister climbed on top of the brother-in-law.
The hips are spread wide below the smooth, slim waist.
Since I was young, I have been held tightly by my older sister.
Of course, after I became a middle school student, there was no way I, a man, could have been pushed by force,
Perhaps because I was beaten so much when I was young, I couldn’t stand up to my older sister.
I have never seen or imagined what a sister like that looks like in front of the man she likes.
The sight of my older sister fawning in front of my brother-in-law like a female cat in heat was unfamiliar,
On the other hand, I was excited because I felt like I was humiliating my older sister by spying on her like that.
The older sister moved her hips seductively, aiming her own pussy at the tip of her stiffly erect glans of her brother-in-law.
Lowering her waist, she pushes her brother-in-law’s cock into her body.
“Huh…”
It is so wet that the big stick goes into my sister’s small lower body without any resistance.
My older sister seems to have climaxed just by having a dick enter her, hugging my brother-in-law’s body and burying her face in his chest, trembling.
Then she begins to slowly and obscenely wiggle her waist.
“Haa… Oppa… I love you… I love you so much…”
A woman who was born to the same parents and grew up together since childhood.
From a childhood when I didn’t know anything,
She remembers her sister’s breasts puffing out and teasing her when she started to put on her bra, and then she got pounded.
She remembers finding her older sister’s sanitary napkin, making fun of it, and then getting hit again.
And the memory of tilting her head when her peers called her older sister pretty as she entered puberty.
And at some point, I also started to look at my older sister sexually, and I even remember secretly going through her older sister’s closet when no one was home, imagining her naked body, and beating her daughter.
Everything that happened to her sister until now passes through her mind.
Then, my older sister suddenly became a man’s wife, and she was having sex in a space just for the two of us and was letting out hot moans,
I was shaking her dick, looking at her nakedly.
My older sister clung to my brother-in-law’s body, who was lying motionless, burying her face in his hard chest and writhing violently on her back.
Since it was my mom, and I’s house, I had to suppress the sound so that it didn’t leak out of the room,
My sister’s movements became more intense and her breathing became faster.
I could see that her sister’s white naked body was getting wet with sweat little by little.
If it had been right next door, you would have heard the sound no matter how careful you were.
My room and my mom’s room are on opposite sides of my brother-in-law and sister’s rooms.
At that time, she heard the door next to her, her mother’s door, opening.
I immediately split the screen so that I could see both the living room and master bedroom cameras.
Mom, wearing only a thin slip, came out of her room and went to her bathroom.
My mother seemed not to have heard anything coming from my sister’s room and went into the bathroom without notice.
My sister stopped moving and was looking at her brother-in-law.
Just like children who got caught doing something bad.
“Mom?”
The sister asked her brother-in-law, but the brother-in-law did not answer.
And after a while, the brother-in-law puts her on her knees and moves her waist up and down, fucking her sister’s pussy.
“Ugh…”
My older sister quickly covered her mouth, but her moans escaped.
The brother-in-law roughly fucked her sister’s pussy from underneath her.
“What are you going to do… Ugh… What are you going to do if you hear it… Ahhh…”
“What’s wrong? Weren’t you hoping for that in the first place?”
“But… Haha… What if it’s Jinwoo…”
“That’s okay too. Don’t you want to show Jinwoo your sexy side too?”
“I don’t like it… I absolutely hate that… Ugh… Stop…”
The sister put her hands on her brother-in-law’s chest and tried to push him away, but her brother-in-law grabbed her sister’s thighs with both hands and lifted her waist with great force.
At that time, I heard the sound of water in the bathroom.
After a while, the bathroom door opens and mom comes out.
Mom still walks to the kitchen, as if she hasn’t heard her.
She then opened the refrigerator door and was about to drink water when she suddenly stopped moving.
Even the bed was shaking due to my brother-in-law’s rough movements.
It was a sound that couldn’t be heard by her mother, who was in a half-asleep state after waking up.
The mother was frozen, holding the water bottle, just listening to her.
My brother-in-law stands up and changes his posture.
My sister tried to escape from her brother-in-law’s hands, but it was impossible.
The brother-in-law grabs her sister, throws her down on the bed, gets on top of her, and sticks his dick between her ass.
My sister’s mouth opens wide as she clutches her bedsheets with both hands.
As her brother-in-law presses his sister’s body on top of her, she again hears the sound of her bed shaking and the sound of flesh slapping together.
“Ugh… Oppa… No… Stop… Haaaaa…”
He was speaking in a whisper, but his plea had now become loud enough to be heard outside the door.
At that time, her mother, who was standing motionless, took a sip of water and put her water bottle in the refrigerator.
Unlike before, the movement was very careful.
Now, it was not my sister and brother-in-law who tried to avoid being caught, but my mother.
Mom slowly started walking towards the sound.
She also seemed to hesitate a little bit from time to time.
She suddenly shook her head and was about to go towards her room.
She stopped and stood for a while, then slowly walked back towards her sister’s room.
Now my brother-in-law shows no signs of trying to hide anything.
She lifts her sister’s hips, grabs her waist and fucks her hard.
I could hear my brother-in-law’s heavy breathing all the way to my room.
If I took the earphones out of her ears, I could definitely hear the sound of flesh hitting my room.
My sister buried her face in the bed with only her ass thrust up towards her brother-in-law, barely suppressing the moans that escaped her mouth.
When I think about it, my brother-in-law and sister clearly knew there was someone out there, but they didn’t know if it was my mom or me.
My brother-in-law thought it didn’t matter either way, and my sister might have actually enjoyed it if it were her mother.
Because it serves her purpose to excite her mother.
Of course, her shame may have been greater.
But because she was anxious that it might be me outside, she resisted her brother-in-law and tried to silence her moans.
Until the very end, my sister did not want to show herself as a woman to me.
The mother was standing quietly in front of her sister’s door, listening to her daughter and her son-in-law having sex.
What on earth was she thinking?
I expected my mom to open that door and join in on her sex, but that didn’t happen.
Her mother turned and started walking back to her room.
And then she really went into her room.
My brother-in-law and sister don’t know what’s going on outside.
My brother-in-law was fucking my sister’s pussy without getting tired.
I’ve already had to stop shaking my dick several times because I’ve been on the verge of ejaculation,
The brother-in-law was pounding his cock into her sister without stopping even once.
My sister was tearing at her bedsheets, her toes were tense.
The brother-in-law neatly gathered his sister’s lovely long hair, which was scattered across her back and on her bed, and grabbed it,
She lifts it up roughly, as if to rip it off.
Her sister’s head lifts, revealing her sweaty face.
My sister was all red from her face to the area around her neck.
Saliva is dripping from her open mouth, and her eyes are turning upward so that only the whites are visible.
“Haa… Oppa… Oppa stop… Hageuuuuu…”
Now my sister doesn’t even seem to have any thoughts about hiding her sounds.
Even though her mouth was begging her to stop over and over again, her sister’s whole body was begging for her pleasure to continue.
The brother-in-law grabs his sister’s hair and plunges his cock into her while admiring her slim, soft body that is curved like a bow.
“Ah … Ah … He’s …
Even though I took the earphones out of her ears, I could hear my sister moaning through her door.
I envied my brother-in-law’s ability to completely paralyze a woman’s sense of reason, and even to paralyze my sister’s greatest shame of not wanting her sister to see her female form.
Then, her mother’s door opened, and she saw her mother come out of the room again.
