Concern on Sehee

18

Siwoo entered his room and took out Sehee's panties from his pocket.

His older sister's words telling him to deal with his erection embarrassed Siwoo, but on the other hand, served as a facilitator that heightened his excitement.

Will Sehee know that Siwoo masturbates with Sehee's panties that she took off in the morning?

At least mom would know.

Mom avoided Siwoo's eyes when she told Siwoo that she was giving her allowance back to Sehee, as commanded by Siwoo.

Even when the back of Siwoo's hand brushed his mother's buttocks, his mother just blushed and lowered her head.

How would she react if he spoke to his mother now?

When that thought suddenly occurred to Siwoo, his heart started pounding again.

Siwoo picked up the smartphone next to him,

And sent a message to his mom.

[mom]

[yes?]

Mom responded with her text.

[thx]

And Siwoo's message is sent again.

[for what?]

Mom's question comes back right away.

[Sehee's allowance]

It was an expression of gratitude for granting Siwoo's request(?).

-By writing letters one by one with his fingers on mom's sensitive buttocks-

Mom didn't answer for a while.

Then

Siwoo got mom's answer about 10 seconds later.

[ok]

At the thought of having a sober conversation with his mother about what happened last night without pretending, a tingling sensation seemed to radiate from Siwoo's genitals.

[but mom, r u ok?]

Siwoo continues talking to his mother.

[ok what?]

Mom's question comes right back again

[that part.. last night right before I went out…]

Siwoo was talking about his mother's nipples which were flicked by his finger as punishment for hitting his older sister's head.

Mom had no answer.

A long time had passed since the number 1 next to the message disappeared, indicating that mom had already read it, and Siwoo became anxious as there was no response.

'Is she angry? Or has this conversation with her son suddenly become uncomfortable?'

Siwoo's heart was becoming increasingly heavy.

Then the message notification sound rings.

[Ugh!!!-_-^]

The last line on the screen clearly says 'Ugh!!!' Along with the words, a cute, angry expression emoticon was drawn.

Siwoo feels excited, as if his body will evaporate and fly away.

Mom expressed her feelings about the immoral and lewd behavior her son did to her last night in the same way she treats her son in everyday life.

He took out his huge erect penis from his pants, wrapped it in Sehee's panties, and shook it like crazy.

Soon the feeling of his ejaculation comes rushing in.

Siwoo's semen was pouring out of Sehee's tiny panties and overflowing and dripping onto the floor.

Siwoo did not clean up the overflowing semen on Sehee's panties and left them there.

At least his mom will know that after Siwoo texted with his mom, he ejaculated on Sehee's panties and tried to show it to his mom.

After changing his clothes and getting ready to go to his academy, Siwoo went down to the first floor and told his mom that he's off to the academy.

"Mom, I'm off~"

"Take care, Siwoo~"

Yes, she was a normal mother as usual.

Seeing his mother acting as if there had been no affair like the previous message, Siwoo's thing seemed to gain strength once again.

Siwoo felt as if there were multiple mothers who treated him differently.

A day mom, and a night mom

And even the shy and naughty mom he met in the chat who can talk to Siwoo as usual and even talk about the night's affairs.

**

When Siwoo opened the front door and came out, Sehee was waiting inside the yard gate.

Sehee got her allowance again, so Siwoo no longer had a reason to go with her, but neither Siwoo nor Sehee mentioned it.

Sehee's face seemed to be slightly red.

Since Siwoo had just masturbated, he was a bit embarrassed to face his older sister who knew about it.

Siwoo and Sehee stand close together, each awkwardly looking away for a moment.

"Shall we go?"

Feeling embarrassed, Siwoo first speaks as if leading his sister.

"Yeah"

His older sister answers obediently and follows Siwoo.

On the way to the academy

Siwoo wondered how long it had been since he last walked side by side like this, alone with Sehee.

Although they bickered every day - almost feeling like he was being bullied - Siwoo was strongly aware that Sehee, like the rest of his family, was a woman that he had to protect.

As the two of them walked, Siwoo continued to think of things to say to Sehee so as not to be awkward, and Sehee followed suit today, especially obediently, and seemed to agree well with Siwoo's words.

"Still, it's a relief that you didn't get your tattoo caught. If mom caught that tattoo, you would have really been kicked out, right?"

Siwoo was jokingly talking to Sehee about her tattoo.

"I was really nervous~! Did you see that even when I was being beaten by mom, I kept covering it with one hand so that she wouldn't notice it? Now that I think about it, it's really funny."

Sehee also accepted Siwoo's words and spoke as if she were happily chatting with her friend.

Sehee's huge breasts were moving dynamically wrapped in a purple bra inside her black mesh box t-shirt as she was being spanked by her mother.

Although Siwoo couldn't check the position of his sister's hand because he was so concerned about her, he was able to imagine his sister's hand down her crotch when Sehee said that.

'Does Sehee masturbate too?'

'Is already having sex? Maybe, if she thinks about exercising by having sex...'

While Siwoo was thinking such bitter thoughts, he suddenly remembered the image of his sister's smooth thighs and the letter-shaped tattoos written on them that he had seen when Shin Bi lifted up Sehee's skirt.

"But do you have a boyfriend? Didn't you say the tattoo was the initials of the person you like?"

Siwoo decides to take advantage of the good mood and ask something he was curious about.

"It's not my boyfriend."

Sehee was denying it so obviously.

"Didn't you say you got a discount because you went as a couple?"

Siwoo continues to ask, looking a little puzzled.

"Oh, I got a discount~ kik, kik."

Sehee playfully teases Siwoo.

"Huh? Then you lied and got a discount? You and Shin Bi were the biggest delinquents~"

Siwoo also speaks to Sehee as if he were joking.

"I didn't lie! It's real love!"

Sehee still talks like she's joking.

"What?! You're teasing me again!!"

Siwoo gets upset because he thinks he was teased.

"What are you so curious about? I'll tell you later, because I like things now"

Sehee's playful face suddenly had a shy expression pass by.

Siwoo, who seemed to figure out something, did not ask any more questions about the tattoo.

On the way to Sehee's academy

Through many conversations, Siwoo seemed to learn a new side of his sister that he had never known before.

-There are still a lot of questions left, but-

When they almost arrived at the academy, Siwoo saw a familiar face in front of him.

The familiar face with a tall stature and a formidable appearance was none other than Cheoljin.

"Hey Siwoo~ Sehee~ Why are you two going to academy together?"

Cheoljin slyly approaches and speaks to Siwoo.

"I have some work to do for the time being. What are you doing here?"

Siwoo is a little surprised to meet Cheoljin in an unexpected place.

"Ah, I also have some business to run nearby."

Cheoljin's tone and attitude are somewhat unclear.

"Cheoljin is busy too? Is there a girl you have a crush on at our academy? Kik, kik."

Older sister Sehee, who was tense due to her conversation with Siwoo, greeted Cheoljin by teasing instead.

"Ah, something similar, haha, since we met like this, shall we go together?"

Cheoljin looked suspicious.

"Then I'll go in. Thank you, Siwoo. Bye, Cheoljin~!!"

The two arrive in front of the academy door and check Sehee is going inside.

After dropping off Sehee, Cheoljin and Siwoo headed to the middle academy they attended.

Siwoo tells Cheoljin about what happened with his sister early in the morning, just in case.

"Oh!! That must have been a big deal. So, Siwoo, you decided to take Sehee to the academy every day?"

Cheoljin reacts awkwardly in surprise.

"Oh, that's right."

Siwoo found that suspicious.

"If something like this happens, I can't just ignore it!! My friend's older sister is going through something like that, so does it make sense for me to pretend not to know?"

Cheoljin raises his voice as if he has been awkwardly possessed by a hot-blooded youth drama main cast character.

He was usually a very open-minded, curious person, but there was some distance from this kind of altruistic proactiveness.

"But weren't you late yesterday? you went home first because you were busy."

Siwoo's interrogation begins quietly.

"Huh?..uh..something happened yesterday. I'm not busy anymore, so don't worry~!! Uh..anyway, I'll definitely catch that shameless stalker~!!"

It was Cheoljin who seemed slightly embarrassed by Siwoo's words.

Siwoo, who did not miss that sight, thought for a moment and then suddenly changed the topic and said.

"Hmm… By the way, Sehee seems to be learning how to dance these days."

"Dance?"

Cheoljin is internally relieved at the sudden change in topic.

"Yeah, I think she's into a certain b-boy dance these days. Was the name B-boying or something? Can you look it up for me?"

"Huh? Oh yeah.."

The moment Cheoljin takes out his smartphone to search it without any suspicion and unlocks it with fingerprint recognition,

Siwoo grabs Cheoljin's smartphone and starts running away.

"Hey, what are you doing!!"

Cheoljin chases after Siwoo in panic.

Siwoo opened the gallery app on Cheoljin's phone while increasing the distance between them.

Secretly taken photos of Sehee with the yesterday's date on them

As soon as Siwoo sees that, his eyes seem to roll over and he rushes towards Cheoljin.
