Building a Friendly Family 50

“W-What… what?”

Shi-woo stuttered, feigning surprise as he belatedly reacted to Se-hee Noona’s words.

Shi-woo had no intention of directly revealing to Se-hee Noona that he had sex with Mom.

He had hinted at Mom’s tendencies while watching a movie, but that was only because he thought it necessary to inform Se-hee Noona about Mom’s submissive nature…

-Because that seemed like the only way to explain Mom’s suspicious behavior, which had recently become more obedient to Shi-woo, to Se-hee Noona to some extent-

Shi-woo hoped that Se-hee Noona would subtly realize the special relationship between Shi-woo and Mom, but that didn’t mean he wanted her to directly associate it with Shi-woo and Mom having sex.

Honestly, Shi-woo also had a secret desire to show off vaguely.

But the primary purpose was to ease Se-hee Noona’s worries and lower her guard.

Se-hee Noona’s implication that she knew about Shi-woo and Mom’s sex made Shi-woo’s heart clench.

A myriad of scenes and words flashed through Shi-woo’s mind in an instant.

Among them were scenes of Mom crying and sobbing in distress.

Shi-woo felt his heart sink.

At the same time, an erotic pleasure exploded within Shi-woo!!!

**

In conversations with Shi-woo, whenever Mom was mentioned, Shi-woo’s bold attitude and reactions, even without directly mentioning it, made it possible to vaguely guess about the reversed relationship between Mom and Shi-woo.

But Se-hee Noona couldn’t possibly know that Shi-woo and Mom had sex last night.

-Unless she came down to the first floor at night to check-

What Se-hee Noona was doing now was probably a playful provocation, fantasizing about what might have happened last night based on her own vague guesses and testing Shi-woo’s reaction.

**

“Why did you stop? You like Mom too, don’t you? Or not?”

Se-hee Noona, seemingly enjoying Shi-woo’s embarrassment, tapped Shi-woo’s arm, which was holding his penis and had stopped moving, with her fingertip, wearing a playful smile on her face as she spoke to Shi-woo.

“Ah… eugh!”

A tingling sensation was transmitted through the skin’s touch and the subtle vibration of his arm to his penis, which was on the verge of exploding.

Urged by Noona, Shi-woo slowly adjusted the tempo and began to move his arm again.

Tak…!

Tak…!

Tak…!!

**

“Yesterday, on the train back home, Shi-woo, you were right behind Mom, weren’t you~?”

Se-hee Noona, watching Shi-woo’s dazed expression as if enjoying it, brought her lips close to Shi-woo’s ear and spoke.

“U-Uh… the t-train was really crowded yesterday…”

Shi-woo stammered, trying to give Se-hee Noona a clumsy excuse that wouldn’t work.

“Why are you pretending now? Did you think I couldn’t see from the side? Kikik, Mom’s expression was something else…”

Se-hee Noona’s saliva-coated lips were now touching and softly rubbing against Shi-woo’s ear as they opened and closed with each word.

“You were probably hard like this back then too, right? How was it rubbing your dick against Mom’s ass? Did it feel good?”

As if playing a role, Se-hee Noona continued her lewd whispers, which were unlike her, in an explicit manner.

Shi-woo recalled the sensation of rubbing against Mom’s ass cheeks on the subway yesterday.

He had wedged his massive thing between the soft, elastic mounds and blatantly pressed his weight against them each time the train swayed.

Mom, completely pressed against Shi-woo, desperately tried to maintain her balance while supporting Shi-woo’s thing with her ass.

Each time Mom braced herself, putting strength into her legs to avoid falling, her ass cheeks would twitch, squeezing Shi-woo’s thing with their flesh.

Shi-woo remembered the pleasurable sensation that was transmitted from Mom’s ass to his penis.

Shi-woo lowered his hand from Se-hee Noona’s chest and strongly grabbed Se-hee Noona’s ass over her dress.

“Ha… really…”

Se-hee Noona said, dumbfounded.

Shi-woo increased his speed towards the final climax.

Tak! Tak!! Tak!!! Tak!!!!

**

“Ah~! It’s coming, Se… Se-hee Noona~~”

Shi-woo quickly pushed Se-young’s pajamas, which he had been covering himself with, to the side and brought Noona’s panties to his glans.

Pshhh~!

Pshhh~!!

Pshhh~!!!

As if trying to release all his lust while embracing Se-hee Noona in front of her, Shi-woo was pouring a tremendous amount of semen onto Se-hee Noona’s pink panties.

Perhaps because Shi-woo’s semen volume was too large, the semen overflowed from Se-hee Noona’s small panties, which he held in one hand, and flowed down Shi-woo’s hand each time he ejaculated.

Shi-woo quickly looked around.

He saw Se-hee Noona’s bra lying right next to him.

Shi-woo released his arm from Se-hee Noona and picked up Se-hee Noona’s bra to wipe the semen flowing down his hand.

Se-hee Noona, breathing heavily, silently watched each of those scenes without saying a word.

The inside of the Ferris wheel, which had passed its peak, was already filled with the thick scent of love and lust that both the male and female had released together.

**

Shi-woo closed his eyes and lay sprawled out for a while.

It wasn’t so much because he was exhausted, but because his head was complicated.

Se-hee Noona’s words, which had made Shi-woo’s heart pound as if implying that she knew about Shi-woo and Mom’s sex while Shi-woo was masturbating.

After that, Se-hee Noona didn’t make any further remarks that would make one associate it with Shi-woo and Mom having sex.

The words Se-hee Noona had said were probably more related to the contact on the subway than to Shi-woo and Mom’s sex.

While he felt relieved, the thrilling pounding that he had felt when he thought that Se-hee Noona had found out about his sex with Mom… the sadistic excitement, the transcendent ecstasy… it wouldn’t leave Shi-woo’s heart.

**

Se-hee Noona took out the pantyhose that she had crumpled up in the shopping bag earlier.

She wiped the fluids flowing on her thighs and crotch and handed it to Shi-woo.

“Here, wipe yourself with this too!!

We can just throw this away anyway.”

“Ah… okay…”

Shi-woo awkwardly received the pantyhose with fluids on it from Se-hee Noona.

The fluids on the stockings still seemed to have a lukewarm warmth that made him feel strange.

“You did that this morning too~! What am I supposed to do if you make my bra dirty like that again? You really came a lot~”

Se-hee Noona said, as if talking about someone else’s problem.

Shi-woo slowly wiped the semen from his hands and Se-hee Noona’s underwear with Se-hee Noona’s pantyhose.

Shi-woo roughly wiped off all the semen and put Noona’s underwear into the shopping bag along with the stockings.

He folded the top of the shopping bag several times, hoping that the smell wouldn’t leak out.

“Go to the bathroom and throw it away as soon as we get off!!

Wipe the underwear with a wet tissue!! Got it?”

Se-hee Noona meticulously instructed him on the cleanup.

**

After the afterglow and cleanup time were roughly over, Se-hee Noona sat in the seat opposite Shi-woo with her arms crossed below her chest and her legs crossed.

-A voluptuously swollen chest, smooth and sleek legs-

With her panties and bra removed, only a thin pink dress was wrapped around Se-hee Noona’s bare body.

The nipples, which were raised one on each side in the middle of her chest, which was gathered by her arms, were drawing a distinct outline as if they would pop out from under her clothes.

The dress was almost rolled up towards her hips, revealing her smooth thigh flesh and barely covering the vulva between her provocatively crossed legs.

Se-hee Noona was looking out the window with a complicated expression, perhaps due to the awkwardness after the deed.

As if possessed by the sight, Shi-woo took out his smartphone and captured Se-hee Noona’s image in a photo.

Click!

Click!!

Click!!!

Se-hee Noona didn’t stop Shi-woo’s actions and left him alone, then glanced at Shi-woo slightly after he had finished taking the pictures.

“In the future, when it seems like you’re lying, I can just make you masturbate, Shi-woo~!?”

Se-hee Noona’s words were incomprehensible.

“What’s that?”

Shi-woo asked, puzzled.

“Why did you treat Se-young’s clothes so preciously, but you just took my bra and used it without saying anything?”

Se-hee Noona seemed to be talking about the situation just now when Shi-woo had moved Se-young’s pajamas and used Se-hee Noona’s bra to wipe off the semen without permission.

Se-hee Noona’s tone was sullen.

“Ah~… sorry, I didn’t mean to…”

Shi-woo, intimidated by Se-hee Noona’s sullen tone, which he didn’t know was genuine or a joke, apologized first.

“Geez~ Shi-woo, you’re too easy, you know? I’ll let it slide this time because it’s Se-young~!!”

Se-hee Noona was talking to Shi-woo as if she had suffered a loss but was generously forgiving him.

Unlike her dissatisfied expression, Se-hee Noona’s legs and toes, which were crossed, were shaking back and forth in the air as if dancing, wagging affectionately towards Shi-woo like a puppy’s tail.
