Building a Friendly Family 30 (Mom, Sehee, Seyoung) (Subway, Department Store)

It was a little past 4 PM when Shi-woo’s family was heading to the department store on the subway.

Perhaps because it was the weekend, there were many passengers in family units or couples.

The train car was filled to a slightly crowded level.

Se-young clung tightly to Mom’s waist as always, showing no signs of letting go.

“Aigoo~ When will our Se-young grow up and live apart from Mom?”

Mom, who was watching Se-young hugging her waist tightly and holding her in one arm, was complaining to herself as if Se-young was too cute but also pitiful.

“Hehe, I’m going to stick with Mom like this forever?”

Se-young said, looking at Mom with an innocent smile.

If Mom was wearing the pink skirt that Shi-woo had picked out in that state where her panties were taken off, then her bare skin would be exposed directly under Mom’s skirt.

Despite that, Mom was disgustingly exchanging such ordinary mother-daughter conversations with her daughter.

Se-hee Noona was across from Mom, busy exchanging messages with someone on her smartphone.

Shi-woo was standing diagonally behind Mom, holding onto the handle.

He was watching Se-hee Noona and Se-young.

Shi-woo was looking for a chance to touch Mom’s butt.

He wanted to confirm whether Mom was really not wearing anything inside her skirt.

It was possible that Mom might have changed her mind and put on panties separately when she changed clothes.

The short pink skirt that continued down from Mom’s slender waist to her voluminous butt line made Shi-woo’s heart flutter and flutter.

Just lifting it up lightly would expose Mom’s bare butt as it was.

Shi-woo mustered up courage and gently brought his hand to Mom’s butt.

Mom flinched in surprise.

Mom knew it was Shi-woo’s hand, so she stood there pretending to be calm without looking back.

Shi-woo straightened his index finger stiffly and slowly moved it down as if drawing a line from Mom’s upper butt.

Mom’s butt panty line did not catch on Shi-woo’s index finger.

Shi-woo felt a sense of fulfillment and lifted his finger off Mom’s butt as if flicking it away.

Mom flinched again as Shi-woo’s finger fell off her butt as if flicking it away.

“Mom, what’s wrong? Are you not feeling well?”

Se-young, who was hugging Mom, felt Mom flinching and asked worriedly.

“Ah… no, Mom just had hiccups, hik-!”

Mom answered as if flustered and pretended to hiccup.

Se-hee Noona, who was using her smartphone, glanced at Mom and Shi-woo.

Shi-woo was happy with this situation throughout.

Mom was surprised to have her butt touched by her son, but she desperately made excuses, even putting on awkward acting to hide such facts from the other family members.

Besides, she could have said something to Shi-woo like in the chat, but far from scolding him, she didn’t even say a word about it.

Shi-woo wanted to harass and embarrass Mom a little more to make her react.

**

They arrived at the department store.

They entered the department store through the passage connected to the subway station.

A super-sized department store with no end in sight.

A super-sized complex shopping mall with facilities such as swimming pools, skating rinks, aquariums, and movie theaters like theme parks.

Se-hee Noona seemed familiar with the internal structure of the department store and was excitedly guiding her family like a dog on a walk.

It seemed that Se-hee Noona had come to the department store often with her friends.

-The expensive clothes piled up in Se-hee Noona’s room were probably mainly bought here-

They decided to buy the clothes Se-hee Noona wanted first, and then slowly look around the department store and continue shopping.

Se-hee Noona seemed to have seen the clothes of the desired brand and design in advance, and she was confidently leading Shi-woo’s family and taking the lead.

“Se-hee, walk a little slower, you’re going to fall~”

Mom said, worried that Se-hee Noona might bump into other people while being so hyper.

“Hurry, hurry~ This way!”

Se-hee Noona urged her family from far ahead.

**

The place Se-hee Noona guided them to was a store in the area marked as a luxury goods section.

An expensive brand that is recently popular among young people.

-Expensive, but students can afford it if they push themselves-

Se-hee Noona said she had seen something before and picked out two dresses on display.

The first was a pink dress with a severely low-cut chest.

It was made of a material that clung completely to the body, so if Noona wore it, Shi-woo might be erect all day long.

-Mom would never allow it-

The second was a horizontal striped dress made of ultra-slim material, which was less revealing because the chest was not cut out.

Even if it was less revealing than the first, it seemed enough to make Shi-woo erect.

Perhaps this was Noona’s trick, carefully devised to get permission for even the second dress.

Shi-woo thought that she deliberately showed the first dress to emphasize that she had chosen something less revealing.

“Both are too tight? I told you not to wear anything revealing? Pick another dress.”

Mom refused Se-hee Noona with a firm expression and suggested an alternative.

Such shallow tricks would not work on Mom.

“Hing~ If I can’t even wear this much, what am I supposed to choose~ All my friends wear this much comfortably~”

Se-hee Noona started to whine in front of Mom as if she was upset.

“Se-hee, are you going to be like that after coming all the way here? Have you forgotten everything Mom said before?”

Mom lowered her voice and created a scary atmosphere.

Se-hee Noona, who knew what would happen if she resisted any further, made a sullen expression and shook Mom as if begging.

**

Shi-woo thought that now was the chance to harass Mom.

He wanted to test whether Mom, who was listening to all of Shi-woo’s requests, would actually listen to requests made openly in front of Se-hee and Se-young.

“Mom, isn’t that okay?”

Shi-woo said to Mom as if he was casually interjecting.

“…Huh?”

Mom seemed a little flustered at Shi-woo’s words.

“If Noona wears that, she’ll look as pretty as a celebrity.”

Shi-woo deliberately pointed to the more revealing first dress.

“That’s… too low-cut and tight~”

Mom said, not looking Shi-woo in the face and seeming troubled.

“But Mom’s skirt seems much more revealing than the dress Noona chose right now?”

Shi-woo said, determined to embarrass Mom.

“Wha… what are you talking about? Why is Mom’s… skirt revealing?”

Mom was stuttering, looking at Se-hee Noona and Se-young as if she was genuinely flustered.

“Even if it’s covered with cloth, if the inside is revealing, it’s revealing!”

Shi-woo teased Mom, driving her into a corner while being conscious of the state under her skirt.

“Hey… what are you suddenly saying?”

Mom was saying with a flushed face.

“There are things that aren’t revealing when other people wear them, but they look more revealing when Mom and Se-hee Noona wear them, so you have to take that into account when choosing.”

Mom couldn’t say anything and was listening to Shi-woo’s words with her head down and her face flushed.

“Noona’s body is inherited from Mom, so if Noona’s body is revealing, it’s Mom’s fault~!”

Shi-woo ended up scolding and condemning Mom.

Mom, who had been listening with her head bowed as if she was being scolded for a while, made a decision in her heart and said to Se-hee Noona with an expression as if she had made up her mind.

“Then… then, Se-hee, why don’t you try changing into that dress and come out? It might be different if you see it in person.”

“Okay… I understand, Mom. I’ll go change and come back…”

Se-hee Noona said, watching the strange atmosphere between Mom and Shi-woo, and headed to the dressing room in the store.

Mom was listening to Shi-woo’s words even while being treated as if she was being scolded.

Se-hee Noona went into the dressing room to change, and Shi-woo, Mom, and Se-young were left behind.

Shi-woo glanced around.

The employees in the store were busy attending to other customers and were not paying attention to this side.

Shi-woo slowly approached Mom.

And in front of Se-young, he stroked Mom’s hair again.

“Mom, you’re really listening well now~ Your face turning red is cute too? I have to give you another reward tonight.”

After that night… this is the third time he’s stroked Mom’s hair.

A public place, and in front of Se-young…

Mom was feeling Shi-woo’s touch as it was, without avoiding or shaking it off this time either.

Mom seemed to be completely compliant with Shi-woo now.

The thought of having such a Mom tonight made Shi-woo’s thing swell with strength.

Se-young said in a small, creeping voice from the side.

“Mom… Oppa… you’re both weird~”

Mom reacted to Se-young’s words and trembled.

Is it shame for betrayal?

Is it a sense of exhilaration for deviation?
