Chapter 251: Chapter 251

Siwoo lay down again behind his blindfolded mother.

Lying on his side, Siwoo pressed his chest against his mother’s back just like before.

Siwoo grabbed his mother’s waist and slightly pushed his condom-covered cock forward, pressing it against the center of her ass.

Then he slightly lowered his hips and rubbed his penis as if burying it along the crack of her ass.

Siwoo wrapped his hand around the shaft of his cock and adjusted the angle.

Siwoo aimed the head and inserted it between the flesh of her inner thighs.

Mom’s groin was soaked with slippery pussy juice.

But her legs were still tensed and clamped shut inwards, as if resisting Siwoo’s invasion.

Siwoo’s cock pushed in, feeling the tight pressure between her thighs.

No matter how inevitable the sexual act with Siwoo was, Seyoung was wide awake right in front of her.

It seemed that Mom had a great sense of resistance to having sex with Siwoo in such a situation.

Siwoo wrapped the leash of the red leather dog collar around his mother’s neck tightly in his hand.

In that state, Siwoo pulled his mother’s leash backward with force.

His mother’s neck was pulled as if it would break, and her body bent backward like a bow.

「Ugh…eut…!」

A short, suppressed moan that was barely audible along with the sound of the bell on the collar came from his mother’s mouth.

The thighs of his mother that had been squeezing Siwoo’s cock also relaxed and parted.

Not missing that moment, Siwoo pushed forward the cock that was wedged between his mother’s thighs.

Siwoo’s huge hunk of meat pushed in smoothly from behind, between his mother’s groin.

Because Seyoung was lying right in front, he couldn’t push his entire cock forward.

But more than a third of the shaft was sticking out in front of his mother’s groin.

It was a position where his dick had broken through the clench of his mother’s thighs and had completely entered between her legs.

Perhaps conscious of Seyoung, his mother’s ass naturally pulled back.

Siwoo sent his hand to the front of his mother’s hips, being careful not to touch Seyoung.

Siwoo grabbed his own penis, which was protruding from between her legs.

He then laid the shaft of his dick towards his mother’s groin and placed the back of the shaft against her vertical slit.

After fitting the shaft of his dick into his mother’s vertical crevice, Siwoo pressed the shaft with his hand, giving pressure and stimulation to the pussy lips it was touching.

In that state, Siwoo moved his hips back and forth, rubbing the sensitive flesh of his mother’s cave surface with the shaft of his dick.

For a good while, Siwoo created friction on his mother’s parted pussy flesh, where the shaft of his dick was buried vertically.

「Ha-euu…haaa…」

Mom began to squeeze her legs together again, pressing down on Siwoo’s shaft with the flesh of her thighs.

Siwoo pulled his chest away from his mother’s back and momentarily stopped his hips.

Siwoo brought the hand that was on his mother’s body to her back.

And just like a little while ago, he raised his index finger and wrote letters on her back.

‘Relax, you fucking cunt!’

With his nail sharpened, Siwoo slowly carved the letters into his mother’s delicate back, as if engraving the pain.

「Haaa…」

At Siwoo’s command written with his finger, his mother’s breath became ragged as if she were out of breath.

Her body trembled once as if an electric current had passed through it, and then, following Siwoo’s command, the strength in his mother’s thighs drained away.

Siwoo prepared to push the shaft of his dick into his mother’s hole.

Siwoo lowered his hips, creating a position where only the tip of his dick barely protruded in front of his mother’s groin.

Siwoo adjusted the angle so that the tip of the head protruding from between her legs would catch on the slit of flesh below his mother’s crevice, and pressed it in with his hand as if prying it open.

As he pushed his pelvis forward and pushed his penis up, the flesh of Siwoo’s glans and shaft, which had been barely hooked on the hole, were momentarily sucked into his mother’s cave.

-Schlorp!

The sound of thick lubricant seemed to be heard faintly from inside the blanket.

「Haup…!」

Mom covered her mouth with one hand and let out a breath mixed with a moan.

Siwoo’s glans, inserted into her hole, was being squeezed by the strong pressure of her vaginal walls.

After inserting his cock into his mother’s vaginal hole, the air changed as if time had momentarily stopped for the two of them.

「Churuup~ Chureup~!」

Only the sound of Seyoung sucking on her mother’s breast could be heard in the room, as if to heighten the lewd atmosphere.

Fortunately, Seyoung seemed not to have noticed the sounds Siwoo and his mother made, as she was busy sucking on her mother’s breast.

Siwoo slid his arm under his mother’s head.

His mother’s head lifted slightly and she lay down, using Siwoo’s arm as a pillow.

Siwoo was lying down with his cock inserted into his mother’s body, in a position as if he were spooning her from behind with his arm as a pillow.

In time with the sound of Seyoung licking the breast, Siwoo tried moving the cock that was hooked at the edge of the hole back and forth a little.

-Squelch~! Squelch~! Squelch~!

Slowly, Siwoo’s penis moved in and out of his mother’s pussy.

A tingling sensation of pleasure was created at the tip of Siwoo’s penis.

「Haaa…haah…ha-euu…」

Mom pushed her ass back and exhaled heavily, substituting it for moans.

「Hngh~!」

Then, intermittently, Mom let out a breath mixed with a moan as if she had let her guard down.

Each time, Siwoo stopped his hips as if startled.

Siwoo turned his head to the side and looked over his mother’s arm to check on Seyoung, who was suckling.

Because the blanket was covering his mother’s chest up to her nipples, Seyoung’s face, as she suckled, was also naturally covered by the blanket up to her eyes.

Seyoung was diligently sucking on her mother’s breast, as if she hadn’t yet noticed the change in her mother’s body.

Or was she aware and pretending not to know?

Seyoung, quietly sucking on the breast, made eye contact with Siwoo who was looking down at her.

Seyoung looked up at Siwoo with sleepy, smile-less eyes.

He felt a rush of blood to his cock, making it swell.

As if he couldn’t hold back any longer, Siwoo grabbed his mother’s hips tightly with one hand and, in that position of looking down at Seyoung, pushed the penis buried in his mother’s body deep inside.

-Swoosh!!

Siwoo’s penis filled up his mother’s insides, grinding tightly all the way to the entrance of her womb.

「Haup!!」

Mom held her breath and leaned her back against Siwoo, her body frozen as if rigid.

Siwoo held his mother’s hips fixed with his hand and was pressing forward with his hips.

Mom was lying down as if being held, using Siwoo’s arm as a pillow, with her vaginal hole completely filled by his cock.

While breastfeeding Seyoung, pierced through the center by Siwoo, Mom was holding her breath as if she didn’t know what to do.

Mom’s shoulders and back were positioned in front of Siwoo’s face.

A humid heat seemed to be rising from her ripe body.

Wet beads of sweat were forming on her back.

The body of Mom, who had been holding her breath without moving, began to tremble, centered around her hips.

「Seyoung must be suffocating because of the blanket~」

Siwoo said to his mother nonchalantly while maintaining the pressure of his hips, his dick pushed deep inside.

Right after speaking, Siwoo grabbed the top of the blanket covering his mother’s chest and Seyoung’s face and instantly pulled it down.

Mom’s upper body was clearly exposed under the light of the master bedroom.

And Seyoung, wearing the pajamas Siwoo had bought her.

The blanket that had been covering Mom was instantly pulled down to her waist by Siwoo.

Mom, her chest and upper body exposed, flinched as if startled.

Siwoo didn’t stop there and stealthily pulled the blanket, which was down to her waist, further down.

A different kind of anxious tension and fear, separate from the trembling caused by the pressure of his penis just a moment ago, seemed to be transmitted from his mother’s body as vibrations.

Mom hurriedly lowered the arm that was wrapped around Seyoung and grabbed the blanket that Siwoo was pulling away.

Mom’s hand, clutching the blanket draped over her upper hips.

If the blanket went any lower than that, her sexual congress with her son would be exposed to Seyoung.

Mom was desperately putting strength into her hand holding the blanket, as if trying to withstand Siwoo’s arm strength somehow.

Siwoo, as if playing tug-of-war, even used his feet to keep the blanket’s position on a precarious boundary.

After a repetition of pushing and pulling, the blanket was lowered as if they had compromised on the position, with both of them slowly relaxing their strength.

Even after Siwoo took his hand off the blanket, his mother’s hand was still clutching the top edge of the blanket draped over her hips, trembling.

That trembling soon spread to his mother’s entire body.

「But now that the blanket is off, Mom must be cold~! I think we should warm her up instead of the blanket, right~?」

Siwoo spoke nonchalantly once more, and put his arm under his mother’s armpit, hugging her body in his embrace.

Siwoo’s arm stretched forward and reached Seyoung’s head.

He then spread his palm and stroked the back of Seyoung’s head.

As Siwoo had said, Seyoung also stretched out her slender arm and covered her mother’s body.

Seyoung’s hand touched Siwoo’s body.

A tingling electric current seemed to flow from Seyoung’s fingertips through Siwoo’s body.

Siwoo took his hand off Seyoung’s head.

And then he grabbed the other breast, the one Seyoung was not suckling.

-As if to prove and show his ownership of his mother’s body-

At that moment, his mother’s vaginal hole twitched as if violently spasming.

Siwoo began the piston movement again, pounding into his mother from behind.
