Chapter 252: Chapter 252

Siwoo squeezed his mother’s breast as if kneading it with his hand and carefully thrust his penis into her vaginal hole.

-Squish! Squish! Squish! Squish~!

「Schlurp~ Schluup~ Schluuup~!」

Seyoung was still sucking hard on her mother’s nipple, from which no milk was coming out.

The sound of the mother and son’s copulation and the sound of Seyoung sucking on her mother’s breast seemed to melt into the lewd heat filling the room, crumbling into fine pieces and scattering into the air.

Siwoo’s careful piston thrusts continued for a good while.

Mom tilted her head back and bit her lip.

And she endured the overwhelming pleasure created simultaneously in her breasts and groin by her son and daughter.

His mother’s nipple was caught between Siwoo’s fingers, which were gripping her breast.

Siwoo put his mother’s hard, raised nipple between his middle and ring fingers and squeezed it with all his might.

「Hngeup~」

A pained snort, as if she’d been caught off guard, shot out from his mother’s mouth.

**

「Is Mommy’s milk tasty?」

Siwoo asked with a pleased expression, looking at Seyoung who was sucking on her mother’s nipple with her mouth covered in drool.

「Yeah~! Mommy’s milk is tasty~ Hehehe~」

Seyoung answered with a bright smile, with her mother’s nipple, from which no milk and therefore no taste should have come, still in her mouth.

Siwoo had definitely smeared the filth that had dripped around his mother’s mouth after dinner onto her nipple.

Along with the command not to wash it off until it was time to breastfeed Seyoung…

That filth was definitely a mixture of the high-proof alcohol his mother had been drinking and Siwoo’s thick semen.

If she could taste anything, it would have been the taste of Siwoo’s semen diluted in alcohol…

On top of that, it was filth mixed with his mother’s and Sehee’s saliva.

Considering his mother’s basic tendencies and her behavior up to this point, there was no way she would have disobeyed the command he had given.

Undoubtedly, Seyoung must have tasted the semen Siwoo had spread on his mother’s breast.

Siwoo was certain of it.

Only after pinching his mother’s nipple between his fingers did Siwoo belatedly realize that Seyoung must have tasted his semen mixed with alcohol.

Siwoo rubbed the pussy juice on his fingers back onto his mother’s nipple.

The pussy juice that was on Siwoo’s fingers was coated onto his mother’s nipple.

「But Seyoung, if you suck so hard on only one side like that, our Seonmi’s breast shape will get ruined and unbalanced~ Hehe」

Siwoo deliberately said his mother’s name, speaking playfully to Seyoung as if to show off his relationship with his mother.

「Here~! Try sucking on this side too~」

Siwoo squeezed the breast he was holding in his hand, making the nipple protrude, and brought it towards Seyoung’s mouth.

The breast of his mother, on which he had evenly spread pussy juice on the nipple with his own fingers.

Seyoung took her mouth off the breast she had been suckling.

And without any hesitation, she immediately brought her mouth to the breast that Siwoo was gripping.

Seyoung took the nipple protruding from between Siwoo’s fingers into her mouth with a gulp.

As she suckled on her mother’s nipple, Seyoung’s lips touched Siwoo’s fingers.

Seyoung licked her mother’s breast without any particular reaction, as if the taste of pussy juice on her mother’s nipple was nothing.

「Chureup~ Chuuup~ Chuuuup~!」

Seyoung created a vacuum in her mouth and sucked her mother’s nipple into her mouth with strong suction.

Before long, Seyoung’s wet saliva dripped down onto Siwoo’s hand.

Occasionally, whenever Seyoung opened her lips, Siwoo’s fingers seemed to touch and graze the mucous membrane inside her lips.

The sensation of when Seyoung had his penis in her mouth came back to him.

Seyoung, who had held onto Siwoo’s dick with powerful suction and wouldn’t let go.

An unbearable urge to cum tingled up from the tip of Siwoo’s dick.

‘Schlorp~! Schlorp~! Schlorp~!’

Siwoo’s penis, swollen as if it would burst, filled his mother’s cave and scraped wildly against the folds of her vaginal walls.

Every time Siwoo’s huge cock moved in and out and the tip of it touched the entrance to his mother’s womb, his mother’s thighs began to twitch and convulse as if out of her control.

Siwoo wondered if it would be okay to cum at this very moment.

Even after smelling the scent of Siwoo’s semen that filled the living room and kitchen, Seyoung had not raised any questions.

He couldn’t tell for sure if she was pretending not to know or if she really didn’t know, but it seemed Seyoung had already grown accustomed to the smell of Siwoo’s semen.

The suspicious behavior and attitude Seyoung had shown Siwoo until now.

The provocative underwear she had worn with Aunt Seonju.

The high level of skinship that shouldn’t exist between a brother and sister.

Those things were more than enough to make him think that it wouldn’t matter if Seyoung found out about his relationship with the other family members.

He was wearing a condom anyway.

Even if the smell of semen was strong after he came, Seyoung would surely either pretend not to know or just brush it off as nothing.

Siwoo wrapped the arm he was using as a pillow around his mother’s head, which was tilted towards him.

And he released the hand that was gripping his mother’s breast and placed it on Seyoung’s back.

After pulling both his arms strongly to take a posture as if hugging the mother and daughter at the same time, Siwoo increased the speed of his hip movements.

-Slap~! Slap~! Slap~!!

Siwoo’s enraged dick was carefully knocking on the deep part of his mother’s vaginal hole, the entrance to her womb.

「Haa… Heut… Haaa…」

His mother’s breaths now came out pitifully, as if she were begging.

His mother’s waist was arching backward from Siwoo’s hips and penis, which were endlessly shaking and thrusting into her.

Siwoo lowered the head that had been looking down at Seyoung to rest on the pillow and began to seriously pick up the pace.

As the piston speed increased, Siwoo’s hand that was on Seyoung’s back gradually moved down.

Siwoo’s hand passed Seyoung’s side and waist and arrived at the area of her ass where the curve began.

Just as he had gripped his mother’s breast, Siwoo tried to grip Seyoung’s ass over her pajamas.

Seyoung’s ass tensed up.

He had touched it several times before, but this was the first time he had ever grabbed it so openly.

And during sex with their mother, no less…

Siwoo pulled Seyoung’s ass towards his mother’s groin, where his cock was inserted, and moved his hips quickly.

Mom, in a fluster, hurriedly raised her knees to block Seyoung’s hips from approaching her groin.

Siwoo brought his lips to his mother’s ear, which was tilted back.

And as if whispering, he spoke into his mother’s ear, announcing his ejaculation.

「Seonmi! I’m gonna cum now~!」

A whisper small enough not to be heard by Seyoung.

「Ha-eut~!!」

A moan she had been holding back escaped from his mother’s mouth in a panic.

She hadn’t thought for a moment that Siwoo would cum while Seyoung was awake.

Siwoo put strength into both his arms and hugged the mother and daughter tightly in his embrace.

His mother’s body began to tremble as if she were having an orgasm.

The dynamic movement of her vaginal flesh, tightening as if to swallow his dick.

-Splooge~! Splooge!! Splooge~!

Along with his mother’s climax, Siwoo caused a violent explosion inside her body.

**

Even after cumming inside his mother’s body, Siwoo kept his penis inside her for a while, enjoying the afterglow of pleasure.

A sensation that didn’t feel real.

In the master bedroom… with both his mother and Seyoung awake…

Siwoo had hugged Seyoung and his mother at the same time and exploded his lust inside his mother’s vaginal hole.

Only the sound of the mother and son’s deep breaths, as if catching their breath, could be heard in the room.

Siwoo’s hand was still on Seyoung’s ass.

For a long time after he had finished cumming, Siwoo was touching Seyoung’s ass.

After catching his breath, Siwoo took his hand off Seyoung’s ass and stroked her back again.

Siwoo lifted his head to the side and carefully observed Seyoung’s expression over his mother’s shoulder.

Seyoung still had her mouth attached to the breast Siwoo had made her suckle.

Seyoung looked at Siwoo, took her mouth off the breast for a moment, and smiled bashfully.

Seeing Seyoung’s smiling face, strength surged into Siwoo’s cock again.

His mother’s vaginal flesh, which seemed to have already climaxed several times, also reacted to Siwoo’s penis, twitching as if in a spasm.

Siwoo pulled his penis back and then pushed it deep inside his mother.

As if to confirm that he could move in and out of his mother as much as he wanted, even while wearing the condom he had cum in…

Just like that, right after cumming, Siwoo repeated the piston motion a couple of times inside his mother’s vpussy.

「Haaaaaaaa~」

Mom let out a long breath.

While making eye contact with Seyoung, Siwoo began to slowly move his hand towards her ass.

Siwoo’s hand moved from Seyoung’s back, past her thin waist, and slid over the swelling mound of her buttocks.
