My Younger Sister Was My First Love

63. Oppa’s Taste

I thought that if I twisted my body in a certain way, space would appear, but…

I had doubts about whether this was the best way, so I tried to find another method.

It wasn’t an easy process.

The handcuffs were too tight, and Jihee would flinch in pain even with a slight movement, complaining that her wrists hurt.

It was as if she wanted me to put on some clothes and play with her a bit.

In the end, it seemed like I had to get on top of Jihee to apply some pressure.

“……Wait.”

I turned my back to her from a distance on the bed.

“Oppa, you’re not going to leave me like this, are you?”

Jihee’s eyebrows twitched anxiously, and I let out a deep sigh.

“I’ll just change my clothes and come back.”

“Clothes?”

“Yeah.”

Jihee was half-naked.

I was also in my pajamas, so the probability of our sensitive areas touching was extremely high.

In situations like this, it’s better to take measures to minimize our embarrassment.

I went into my room, grabbed some sleep pants and a puffy padding, and put them on before re-entering Jihee’s room.

My reflection in the mirror looked like a firefighter trying to put out a fire.

“……Oppa.”

“Yeah?”

“Won’t you feel uncomfortable wearing something that thick and trying to put your arm in?”

I let out a silly “ah” sound in response to her piercing question.

Why do I become so stupid in front of Jihee?

The padding was inefficient in the narrow space.

In the end, I took off my armor-like outerwear and slowly lifted my knee onto the bed.

“……Don’t say anything later.”

“When have I ever said anything about this?”

“No, I’ll put your pants on for you instead.”

“……Will you?”

I thought it was better to put her pants on than to leave her in her underwear, but…

Maybe that wasn’t a very wise choice, and the thought crept up on me.

I brought her sleep pants and Jihee lifted her legs comfortably, as if asking me to put them on quickly.

Her white, slender calves.

Her ankles were so thin that I worried they might break if I touched them wrong.

Her pretty feet were wiggling, as if asking me to put her clothes on quickly.

It didn’t feel like I was doing anything wrong, but a strange sense of shame arose.

Why did it feel like undressing her was just as embarrassing as this process?

My hand slowly moved up her calf, brushing against her thigh area.

The destination was around the buttocks, passing the pelvic area.

“Thank you.”

Jihee, wearing only a bra under her pajamas, looked at me straight in the eye with a sly smile.

“Are you going to take it out now?”

“Yes!”

The permission was granted.

As I slowly lowered my upper body, my thighs and Jihee’s thighs slowly overlapped.

Even with the sleep pants on, I could feel a strange, thrilling sensation.

Moreover, since this was Jihee’s bed, the sweet scent of her body kept tickling my nose.

With my hand reaching behind Jihee’s shoulder, onto the back of the bedhead, I wanted to dive deeper inside like a deep-sea explorer.

As I got closer to the bottom, my face naturally tilted towards Jihee’s nape.

I tried not to be conscious of it, focusing my senses on the tips of my fingers as much as possible.

“Is it really in here?”

Fumbling around.

I swept my fingers around in the dark, invisible space.

“Does it seem like it?”

“What does it seem like?”

“You did put it in, didn’t you?”

“Are you sure?”

Although the answer was a bit suspicious, I continued the exploration with enthusiasm.

No matter how foolish it seemed, I couldn’t leave it like this.

But, unlike my expectations, the key didn’t appear no matter how many times I searched.

My anxious heart made my movements increasingly urgent.

“Hmm…!”

As a strange, thrilling sensation echoed in my ear, I was startled and sprang up like a spring.

“Did you find it?”

“No.”

“Why did you get up?”

“…You made a weird noise.”

Doesn’t that person know what’s weird?

“But, oppa, it seems like… that…”

“That what?”

“The lower part…”

As soon as she said “below,” I naturally became aware of my lower body.

No way, really no way?

“No.”

“Is it not?”

“No, it’s not.”

On the contrary, you’re the one who’s making me aware of it by talking about it!

Who’s the one who’s searching deeply while reciting a Buddhist scripture, yet still teasing people?

“So? Then do it again.”

“Ah. Please attach the objective case.”

“Make it reach all the way in?”

“You know I got first place in the national language proficiency test, right? Don’t pretend you don’t know.”

You know the subject and object perfectly well!

The mischievous teacher-like person chuckled and wrapped their legs around mine, pulling me close.

“Don’t do that and just hurry up. Are you enjoying watching me tied up like this?”

“I don’t have that kind of hobby.”

“That’s a bit disappointing, though.”

What’s wrong?

What’s disappointing?

“Ha… anyway, just bear with it for a bit.”

After putting my hand in deeper, I was finally able to find a key that was slightly larger than my fingernail.

“Whew…”

I, who had almost taken a flexibility test without breathing, quickly tried to insert the key into the hole as soon as I stood up.

“Jihee.”

“Yes?”

“What’s this?”

As soon as I pressed the protruding part on the side of the lock, the handcuffs made a clicking sound and came undone.

“Oh.”

What’s with the “oh”?

“Be honest. You knew this, right?”

“No.”

“You didn’t know this? There was even a manual inside, wasn’t there?”

“I never read the manual.”

“Yeah.”

“And I got 7th place in the college entrance exam! You’re stupid! You could not know!”

Anyone could see that the tone was playful, but the blood pressure was rising.

It’s always like that when it’s convenient for them, talking about grades.

Ah… I got tricked again…

Wait, is it possible that I got tricked because I’ve never played with handcuffs before…?

“But still, since it’s a toy, it’s giving me a way out, right? If it was real, it could be used for crime.”

Jihee fiddled with the unlocked handcuffs, then reconnected the ring and spun it around.

“…… I’m leaving.”

My energy was drained.

“When are you going to study?”

“Wear some clothes and call me again.”

“Since you’re already dressing me up, can’t you put a shirt on me too?”

“Is that okay?”

I had already done more than enough skinship, and all I could think about was getting out of there quickly.

Just the experience of putting on pants was enough to make my mood pretty strange.

“Thanks, oppa.”

Jihee, who had gotten out of bed, put on a T-shirt and turned her head towards me.

“I feel really reassured.”

“What is it?”

“Don’t you think that if something urgent happens to me, oppa will somehow take care of it?”

“No way. If it’s a real emergency, I won’t do something like this, I’ll just jump in and help, without you taking off your clothes and getting handcuffed in some weird place.”

“Got it.”

It felt like I was being lectured about everything.

The scope of home education was too broad.

“Ah… let’s start the questions in 10 minutes.”

“Okay!”

I was 21 years old.

How many oppas in this world would put on pants for their younger sisters?

As time passed, more and more episodes that couldn’t be counseled accumulated in my head.

* * *

It had been three weeks since Minju unnie came to our house under the pretext of tutoring.

“Jihee-ya!”

She came in with a bright smile, but I knew her true intentions and couldn’t welcome her with open arms.

Someone who liked our oppa.

If our parents’ marriage had been delayed just a little, this person could have been our oppa’s girlfriend.

“Hello, unnie!”

“Did you finish your homework?”

“Yes, I did. You came all the way here to help me, so I wouldn’t dare not do my homework.”

I forced a smile and laughed.

This was our way of communicating.

Underneath the surface, our intentions were different, but our lesson proceeded smoothly.

Unnie taught me diligently.

I accepted it sincerely.

To be honest, the level of teaching was not much different between oppa and unnie.

Both used a tone like a private tutor.

Both seemed like people who were skilled in their studies.

“Minju.”

Unlike Yuhan unnie, oppa was watching us with a strict parental gaze, his arms crossed.

He was calling unnie, but his eyes were on me.

His anxious expression, hoping I wouldn’t do anything strange.

It was quite reassuring to see him completely focused on me.

Yes.

I need to concentrate.

Thinking back on the events I had worked hard on, I thought this attitude was a very reasonable treatment.

I also wrote letters enthusiastically.

I even pretended to be alone and enthusiastically did a show.

To be honest, I did it myself, but it was ridiculous, and yet, Oppa always gave me a reaction that exceeded my expectations.

Irresistible addiction.

Watching Oppa, who was becoming more and more charming every day, was like melting my heart, which was as hard as a rock from studying for the college entrance exam.

Just as office workers have a beer after work to unwind, I had Oppa, one spoonful of healing.

Let’s slowly start our cute teacher’s removal operation.

I gently placed my hand on Minju unnie’s waist and waved at Oppa, leading her to my room.

“Ah, right. Jihee-ya.”

As soon as she sat down, unnie seemed to remember something and clapped her hands.

“What?”

“Did Junho mention the MT?”

“MT?”

“Yes. He said we’re having a summer MT.”

It was a story I had never heard before.

The fact that Oppa didn’t tell me about it meant that the results weren’t confirmed yet.

I decided to listen to the explanation a bit more.

“When is it?”

“In July. So, I was thinking, could you understand Junho going?”

“Me?”

“Yes. You know, Junho almost never hangs out with the kids until late at night and comes to see you instead.”

Ah-ha.

So, you’re trying to score points with that route?

I slowly nodded, seeing through her obvious strategy.

“That’s right?”

“Junho might want to take a few days off and go on a trip, feeling like he’s on vacation.”

Having roughly estimated the situation, I started preparing a countermeasure.

“It’s definitely reasonable, unnie. Our Oppa needs to take a break too. It’s not like I’m watching him every day.”

“Yes. The seniors at the academy also want to go with Junho.”

It might be a bit rude, but I cut off unnie’s words.

“But even if Oppa goes, he won’t be able to have fun comfortably.”

What’s with people trying to manipulate others like that?

“Would Oppa really be able to have fun comfortably if I’m alone at home?”

“No, just for a day.”

“Is the reason you’re telling me this now because Oppa already rejected it once and you’re trying to convince me?”

Checkmate.

Minju unnie and our Oppa were both like that.

These people really lacked talent in acting.

“Then, how about I suggest that I go on a trip with Oppa instead? I haven’t been able to take care of Oppa’s feelings well enough!”

“No, you…”

You could already see the reaction, “Is this really not it?”

It’s already too late.

The atmosphere had already shifted to this side.

“Do you really need to study?”

“Of course! As a student, you can’t slack off for two days. Plus, July is the real deal, so it’s the perfect time to buckle down.”

The answer, which lacked even a hint of creativity, felt suffocating.

“Unnie.”

“Hmm…?”

“Do you want a tip from me?”

“What kind of tip?”

I gently placed my hand on the shoulder of someone who was already at a level where it was embarrassing to call them a rival.

“Sorry, but our oppa doesn’t really like the model student type.”

Boom.

It was the moment when Unnie’s mask shattered.
