A Secret Exercise

8

After Sehee's scolding, They sat down at the table and ate the ramyeon that Shin Bi had cooked together.

"We all got these together today~"

Shin Bi's soft voice

She said that the tattoo that Sehee got was a friendship tattoo that was popular among high academy girls these days.

Each person has the name of their favorite partner or celebrity engraved on their thigh with English spelling in the same font design.

Since it is small and placed on the inner thigh below the groin, there is no chance to get caught by parents unless she plans to lift her skirt like just before.

"We went to the tattoo shop together and got a discount. We got an extra discount because we were high academy students. Sehee and I chose the names of people we like. They said they would have offered more discount if we came as a couple."

Sister Shin Bi explained in detail things that were not even asked, using her quiet tone and unique accent that made people relax.

Siwoo nodded his head while listening to her, eating ramyeon.

According to what Shin Bi said, it seems that both Sehee and Shin Bi have people they like.

Siwoo didn't know if they were dating the person with the initials or if they just had feelings for the person, but he didn't really feel like asking.

"Shall I show you mine too?"

Shin Bi, who was sitting next to Siwoo, turned her knee towards Siwoo and asked.

SiWoo, who was eating his ramyeon, cleared his throat as if something caught his breath at Shin Bi's sudden words.

"Ugh… gasp… what.. what?"

"You want? Aren't you curious?"

Shin Bi held the top of her skirt with both hands and pretended to slowly raise it.

Shin Bi's already short academy uniform skirt was brushing over her plump thighs and rising toward her pelvis.

'Gulp!'

Siwoo was staring intently at Shin Bi's thighs, swallowing his dry saliva once.

Suddenly, her skirt stopped moving up and Shin Bi spoke in her sinister voice.

"Your eyes brightened?"

Then she slyly slides her skirt back over her thighs.

"I guess you thought I was really going to show you~ Hahaha"

Shin Bi's teasing voice and the sound of her laughter were echoing through the house.

Siwoo was momentarily embarrassed.

"Your little brother is so cute~ Did you see his face blushing?"

Shin Bi, with her playful expression, spoke to Sehee.

Sehee, who was sitting across from him, was watching the scene in silence, feeling sorry for him.

"Did you ever expect it?"

Shin Bi hit the nail on the head of Siwoo and teased him until the end.

"Oh~ no!!!"

Siwoo didn't like this situation where even Shin Bi, whom he trusted on, was making fun of him, so he gave an irritated response.

"Hahaha~"

Radiating the vitality of a high academy girl, Shin Bi held her stomach and laughed for a long time.

Siwoo said, eating his ramyeon:

"Your partners will keep changing, so you guys will definitely regret the tattoos later," 

"Well, I guess you just have to pick men with the same initials and meet them,"

"Would it be a good idea to change the name of the man you meet?" 

He was trying to make up for his loss of face by being teased, by saying bad things like these.

However, due to Shin Bi's coaxing and soothing tone of "Yeah, yeah, that'll work" every time, such attempts didn't have much effect.

"But Sehee, if mom catches it, won't you be in real trouble?"

This time, Siwoo asked Sehee, his tone showing that he was seriously worried about Sehee.

"If you just keep your mouth shut, there will be no problem, right?"

Sehee is still cold to Siwoo.

"Are you not going to go to the sauna or swimming pool with Mom at all from now on?"

Siwoo said to Sehee that he was still worried.

"Yeah, I said as long as you keep your mouth shut, there will be no problem!"

Sehee repeats the same words and replies coldly to Siwoo.

"Ah, do you think I am going to tell mom about that?!"

Siwoo was also starting to get annoyed by his older sister's attitude.

Now Siwoo decided to stop talking to his sister.

It seems that Siwoo's joke in yesterday morning offended his older sister, making her very angry.

When his father passed away and his family was in a state of dismay, Sehee's boobs grew bigger and she quit her sports, which she had been working hard at earning good grades.

Although Siwoo heard about it from Shin Bi, Sehee may have been reluctant to reveal the reason to her family.

Sehee never thought of sports as a career, so she didn't have a very hard time about quitting sports.

However, she might have been deeply upset by the situation where she could not confidently reveal the reason of quitting sports, even though she knew keeping it secret would cause concern to the family.

That sensitive part was where Siwoo touched on.

Shin Bi, who was watching next to them, seemed to feel sorry for Siwoo and started playing tricks on him again.

"Do you have a girlfriend?"

"No, I don't"

Siwoo answered right away without thinking much.

"Have you ever been in a relationship before?"

"No, I haven't"

"Have you ever kissed?"

"Why are you asking me about kisses when I said I've never been in a relationship?!"

Siwoo said with embarrassment.

"Oh, can't you kiss even if you're not dating?"

"I said I haven't!!"

Shiwoo was a little surprised.

It's not wrong to say that you can kiss even if you're not in a relationship, but shouldn't it usually be done between lovers? He thought.

-Separating delusion from reality-

"Are you not interested in those things?"

Shin Bi's face creeps up on Siwoo.

"No, it's not that I'm not interested, but it's strange to answer questions like that."

Siwoo becomes more and more embarrassed as he can't see her eyes.

"Do you want me to teach you how to kiss?"

Shin Bi was looking straight at Siwoo with her glossy lips covered in pink lipstick pressed together.

"...."

Siwoo was frozen in that position and couldn't do anything but looking at Shin Bi's lips.

"Ah~ you thought about it for a second, right? Kissing me."

Shin Bi becomes her playful voice again and says.

"Ah, enough!! What are you talking about!!"

"Siwoo is sooo cute!! Haha~"

Shin Bi held her stomach and laughed again.

Siwoo continued to be teased by Shin Bi, so now he was just eating his ramyeon and just listening to the conversation between Sehee and Shin Bi.

"Ah, but I can't dance. It makes me sweat a lot, but it's so difficult. It's hard to use muscles I haven't used before."

Sehee seemed to be talking about the dance she was practicing earlier.

"Yes, that's right, I think it's definitely a difficult dance for beginners to do."

Shin Bi answers, agreeing her.

"Would it be a good idea to do THAT? Are you okay with that?"

Sehee seemed to catch Siwoo's attention and then she said, 'THAT' and asked Shin Bi.

"Hmm... I honestly think I can do THAT if it's together with you."

Shin Bi answered Sehee's question carefully.

"Yeah, I think we can do THAT if we do that together, right? It can wait until I answer Sora about that, so think about that a little more."

Sehee concludes the story as hiding something while observing Siwoo's feelings.

"What are you talking about? Exercising for losing weight?"

Siwoo suddenly becomes curious and asks.

"You don't have to know?"

It was Sehee who blocked Siwoo's questions with a cold tone.

"Ah, what are you talking about? Shin Bi, what are you talking about? Huh?"

Siwoo, thinking that he cannot get an answer from Sehee, immediately asks Sister Shin Bi.

As expected, Shin Bi speaks kindly while observing Sehee.

"I'm sorry Siwoo~ I don't mind if I tell you, but I think Sehee will be really angry if I do that."

"Oh really, what is that?"

Siwoo's voice became grumpy due to his frustration.

"You don't have to know!! You've finished eating the ramyeon, now go do the dishes!!!"

At Sehee's annoyed words, Siwoo couldn't ask any more questions and ended up doing the dishes.

Sehee and Shin Bi were sitting on the sofa in the living room, watching TV and chatting.

Siwoo was listening with his ears prickled and eavesdropping on the conversation between the two, but nothing related to 'THAT' came out.

Siwoo thought to himself while washing dishes.

'There is something'

'It was obviously about an exercise for losing weight, but why is my sister so angry if I find out?'

'Is that an exercise that she would be embarrassed to tell her younger brother about?'

'I'm even more curious because even Shin Bi keeps it a secret.'

Siwoo kept thinking about it, but no answer came out.

When the dishes were almost finished, Sehee, who had been chatting with Shin Bi in the living room, got up and said she was going to the bathroom.

A while later, while Sehee was in the bathroom, Shin Bi came over to Siwoo in the kitchen and spoke to him.

"Would you like me to help you with the dishes?"

Shin Bi's usual nonplayful voice

"It's all over, so it's okay~ Rather than that, wasn't it about the exercise that you were talking about when we were eating ramyeon?"

Siwoo quickly asks, thinking that Shin Bi might tell him when Sehee is not around.

"That's right"

Shin Bi answers obediently

"But what kind of exercise is Sehee going to get angry if you tells me?"

"There is such a thing hehe"

She was still mysterious and did not give a cool answer.

"Ah~ Are you really going to do that to me, Shin Bi?"

"I'm sorry, but I think Sehee will get really angry if I tell you."

Shin Bi keeps the secret.

"That's too much~ You were just teasing me earlier, and now you're even picking on me and making me feel left out. How many years has it been since you and I have seen each other!!! Can't you just tell your close boy?"

Complaining about his disappointment, SIwoo appealed to Shin Bi.

Shin Bi looked troubled.

"Don't be so sad~"

And she thought for a moment and then she said:

"I don't think I can, she'll get really angry. Then, I'll give you a hint instead."

Saying that, Sinbi wrote numbers with her finger all over Siwoo's back as he was washing the dishes.

'0'

'1'

'3'

'5'

After that, Shin Bi sweeps Siwoo's back as if she were erasing the number with her palm

"0135?

Siwoo looks puzzled and turns his head slightly back to check with his sister.

"Shh!!"

Shin Bi motioned with her hand to be quiet and made a 'shh' sound with her mouth.

"Even if you figure out the answer, you have to pretend not to know to Sehee, okay?"

Siwoo nodded his head.

And until Shin Bi went home, Siwoo didn't say a word as he pondered on the hint.
