“So, you were being bold and doing well? What were you going to do if I hadn’t accepted you today?”

Sejin sounds like she’s still smiling, teasing Siwoo’s recklessness.

“Uh…uh?”

Siwoo awkwardly twitches his body in response.

Contrary to his twitching body, Siwoo’s penis is expanding inside Sejin’s vaginal opening.

Siwoo’s penis was widening Sejin’s vaginal opening even more tightly.

“Haa…ha…huut!”

Sejin lets out a moan as if she is collapsing.

Siwoo had never thought that Sejin would refuse to have sex with him until he came to the officetel…

No, for some reason, Siwoo was almost certain that he would have sex with Sejin.

However, in the conversation Siwoo had with Sejin, he realized that she was not a submissive person like his mother or Aunt Seonju.

If that wasn’t the case, there would have been no reason or meaning to follow a parental slavery contract…

When he thought that Sejin might not have responded to his request, he felt so embarrassed that his whole face flushed.

“I, I would have raped you! If I had pounced on you as soon as I saw you, what would Sejin have done?!”

Siwoo puts on a false bravado to hide his embarrassment and speaks as if he is strongly pushing her.

Squish! Squish! Splat! Splat! Thud thud!

At the same time, Siwoo roughly moves his pelvis, ravaging Sejin’s hole.

“Haaung~ haa euuu…hawooong…haaaang haoong haaang…”

Sejin moaned, bending her back.

“Ha…well…even if I was raped by you, Siwoo…huut…ah, I wouldn’t have been able to say anything…heueueueu…but…ah, you shouldn’t do that to just anyone…”

Sejin, with her penis deeply inserted into her, spoke in a thin, trembling voice as if giving a warning.

At that moment, Siwoo’s penis felt like it was enveloped in tingling thrills and pleasure.

“If I knew it would turn out like this, I should have pounced on you when you were walking around the house in just your panties after showering!”

Squirm squirm squirm! Squirm squirm!

Siwoo provokes her by saying that while stabbing his penis into Sejin’s vaginal opening.

“Haaung haaaa…hawoooot…! Haaang haaaa…”

Sejin was moaning, moving her pelvis back and forth as if accepting Siwoo’s penis.

“What would it have been like back then? Without Dad knowing… If I had pounced on you with the intention of raping Sejin? Would you have accepted me like you are now?”

Siwoo asks Sejin, testing her, by assuming a lewd situation in a vulgar tone.

Siwoo is thinking about Sejin’s appearance when she was walking around half-naked after taking a shower at home back then.

Siwoo savors Sejin’s vaginal opening, thinking about having sex with her back then.

A climax that made his spine tingle spread throughout Siwoo’s body.

“Ah…without Dad knowing? Heueut…!”

Sejin takes a breath and asks as if checking the details of Siwoo’s question.

Swish! Swish! Swish!

“Yeah! Keep it a secret from Dad! And without the other family members knowing…”

Siwoo said, stabbing his penis deeper as if testing her reaction.

“Haa… haa…if you had pounced on me without anyone knowing back then…haa…haeuut haaa…”

Sejin trails off as if she is worried.

“If I had pounced on you without anyone knowing back then?”

Siwoo repeats Sejin’s words as if urging her to continue.

Thwack! Thwack! Thwack! Thwack thwack thwack!

Siwoo’s piston movements were getting rougher and faster.

“Ah, maybe… ha…I think I would have let you…heueung…i, if it’s this much…heueue…heueueut…haaeungeu….ha…haeuut…”

Sejin, squeezing her vaginal opening, whispers to Siwoo in a scattered breath and voice.

Siwoo momentarily stops his waist and takes his hand off her clitoris, which he had been rubbing.

Then, after holding his palm in the air, Siwoo slaps her butt hard.

Smack! Smack! Smack!

The resounding popping sound echoed throughout the officetel room.

“Haaeuung haaaat haaeueueung!

She moans almost as if she is about to cry.

The appearance of the eldest sister, who had dignity and grace, can no longer be found in her.

“You fucking bitch!”

Siwoo curses after slapping her butt, and then continues his intense piston movements.

Splat splat splat! Chwup thud thud thud thud!

Siwoo was showing off a violent pounding that was almost like hitting her butt with his pelvis.

A violent and crude movement that made him worried that his internal organs or the entrance to her uterus might be pierced.

Siwoo’s penis is being violently stabbed into her vaginal opening all the way to the root.

“Haaung haaaang haeuk! I, I’m sorry…haaung… Master…haaaat! I was wrong~ haaang Master! Haaaeuung”

Sejin calls out to Siwoo as if begging for forgiveness in polite language.

Sejin bends her back completely and raises her legs toward her stomach as if trying to protect her internal organs and uterus from Siwoo’s violent pounding.

Siwoo grabbed Sejin’s pelvis to prevent her from escaping and fixed her position.

Then, Siwoo slams her pelvis from behind with all his might.

Shuka shukak shupak thud seubeok seupeok thud! Thud! Gagak! Bbuak!

A sound like muscle fibers tearing is heard from deep inside her.

“Haaaak haeuk haaaat haeeueueung… Sa…save me! Haaung! Master! Haaang haaaat!”

Eventually, Sejin is desperately shouting a safe word to be saved.

Thwack!

Siwoo hears the safe word that Sejin is shouting and inserts his huge penis deeply into her vaginal opening for the last time.

“Hawooooo! Woouk woooo…woogeugeuk…hageuk hageueueuk!”

She gathered her arms and legs forward like a fetus, bent her back, and trembled.

Her electrifying tremors are transmitted through Siwoo’s heavy penis in her hole.

Siwoo’s penis stretched her vaginal opening beyond its limits and was pushed deep inside her.

Siwoo pushed his huge penis all the way into her vaginal opening until Sejin’s trembling subsided, stopped moving, and hugged her pelvis from behind.

Siwoo gradually loosens his strength, slowly releasing the pressure from his arms hugging her pelvis and his inserted penis.

Just as pleasure and pain were melting into lingering feelings and she was relaxing and letting her guard down…

Smack!

Siwoo slapped Sejin’s butt hard with his palm.

“Haeuk!”

Sejin’s body startles and jumps.

Siwoo strongly grabs Sejin’s butt fat and suppresses her body to prevent her from escaping.

As Sejin’s trembling and commotion subsided, Siwoo released his hand that had been grabbing her butt.

Siwoo begins to gently stroke her butt cheeks with his palm as if tickling them.

“Haaa…haa…haeuut…haa..haoot..hawoooo…”

Sejin struggled to calm her breathing while trying to endure the burning and stinging sensation in her butt.

Sejin is trying to calm her breathing, but she is also nervously tensing her body, thinking that Siwoo’s palm might slap her butt at any time.

Siwoo pats the hand he has placed on Sejin’s butt.

Then, Siwoo gently strokes her butt as if expressing that there will be no more spanking.

“Haaaa…hooouuuu…haaaaaaa…heueu…haaaaa~”

Only then did Sejin let out a long breath and release the tension that had been tightening her whole body.

**

“Siwoo, you…heueu…did you want to rape your sister that much?…haa…still, she’s pregnant…heueu…”

Sejin, lying on her side and stretching her body completely on the bed, says as if she is dumbfounded while calming her rapid breathing.

Sejin had already returned from a vulgar slave to Siwoo’s eldest sister.

“Huh? Uh…no…that’s…”

Siwoo responds, embarrassed by Sejin’s attitude of speaking to him as if she is joking.

“Wow…Mom and Sehee must have suffered a lot…haa…to have such a big thing inserted and stay up all night… It’s not like they’re just standing still, they must have been pounding like you were earlier… Haeup…”

Sejin said to Siwoo, wriggling her vaginal walls as if trying to gauge the size of his penis again.

Siwoo hesitated for a moment, not knowing what to say.

Even while he was hesitating, Siwoo’s penis was twitching and wriggling.

“Heuheut…haaat…b, but aren’t you going to cum, Siwoo?…I think I’ve come more than five times…”

“No! And didn’t you already cum inside me once? How can you keep standing without resting?”

Sejin was asking in amazement, with a breathless voice, before Siwoo could even say anything.

Could it be because of the embarrassment of experiencing an overwhelming climax against her younger brother?

For some reason, Sejin was pouring out her condition and feelings in words like a chatterbox.

Siwoo’s penis swells up again inside her vaginal opening.

Sejin quickly puts her hand down and puts it between Siwoo’s pelvis and her butt.
