My Little Sister, Cha Dohui...♥

As the product's outline became clearer, our presentation boot camp came to an end.

The reason was simple: there was no longer any need for us to work overtime at Seo-hye's place.

Seo-hye would manufacture the product, and I would just provide the silicone.

All that was left for me to do was create the PowerPoint.

Damn my big mouth.

I should have kept it shut a little longer.

Early morning.

Waking up with Seo-hye under the fragrant blankets was something else.

As I watched her sleeping peacefully, resting on my arm, I wondered if this was all a dream. I placed my hand over her massive breasts.

The sensation was incredibly vivid.

The fact that my morning wood grew even harder confirmed that this was indeed reality.

Perhaps because I touched her breast, Seo-hye seemed to wake up.

"Mmm...?"

She turned toward me and snuggled deep into my chest.

I pressed my lips against her small head, which was barely the size of one of her breasts.

Along with the soft blanket, her tender skin was the definition of softness itself.

Moreover, though her breath fanned across my chest, there wasn't even a trace of morning breath—a natural phenomenon I fully expected.

Without realizing it, I stroked her hair.

How should I put it?

It felt like holding a favorite plush doll.

I was also grateful to her for carefully swallowing my cum the night before.

Stroke, stroke.

As I gently caressed her head, she stirred and sat up.

"...Dohyuk. Are you awake?"

"Yeah. Did I wake you?"

"I had to get up anyway... Mmm."

Seo-hye burrowed even deeper into my arms and lightly kissed my lips.

Smooch.

At the exact moment that pleasant sound echoed, another, far less pleasant sound rang out.

Beep-beep-beep—

The alarm.

It was time to get ready for work.

"Do you want to... eat breakfast before you go? I can make toast?"

"I'd love that."

A breakfast made by a woman.

This was basically... cohabitation, wasn't it?

I felt like I had checked off one of my biggest bucket-list items.

However, I had to drop by my place first.

I needed to change out of my ruined underwear and dress shirt.

"Then... let me go. Aren't you holding me a bit too tight?"

"Ah, sorry. I'll go home, wash up, and come back. Let's eat toast and head to work together."

"Okay. See you soon."

Feeling a lingering regret, I kissed Seo-hye's lips one more time.

After all, this might be our last kiss.

.

.

.

Home.

It was quiet.

It seemed my younger sister had gone to school.

Ah, just in case anyone gets the wrong idea, my sister is twenty years old.

And...

"Ah. Yesterday was her birthday. That's why she called."

Moreover, a cake with a single slice taken out of it and unlit candles sat lonely on the dining table, telling the story of last night.

"...She should have just spent it with her friends. Did she seriously wait for me? Silly girl."

I cracked Dohui's bedroom door open.

Her bed was neatly made, and her desk was tidy.

She must have left for school early, busy with college life lately.

It was admirable to see her taking care of herself like this.

My payday was still far off, but I figured I should scrape together my emergency funds to buy her a laptop.

Then, I checked my own room.

First of all, the piece of paper I had wedged in the doorframe was gone.

Which meant someone had ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠entered my room.

Since my parents were staying at my grandmother's place, it had to be Dohui.

I opened the door and scanned the room.

There was nothing to take in here, so why did she keep coming in...?

Dohui's habit started three years ago.

Specifically, the year I turned twenty, when she caught me with an Onahole my friends had gifted me as a joke.

With a sly expression, what did she say again?

"I knew not that my brother possessed such a noble hobby. This is remarkably similar to my own..."

I barely managed to shut her mouth before she could finish that dangerous sentence...

Ever since then, searching my room whenever I was out became a routine for her.

Personally, I believe privacy should be strictly respected.

I had warned Dohui every time she entered my room, and she claimed she would lay off for a while to celebrate my new job. Indeed, she had been holding back lately...

But it seemed my failure to celebrate her birthday yesterday had reignited her curiosity.

Furthermore.

Sniff, sniff.

A faint floral scent, completely different from my own, lingered in the room.

I searched for the source of the smell and eventually reached my bed.

My pillow and blanket were drenched in the perfume Dohui usually wore.

"Hmm... This is Dohui's scent. It's all over the bed."

Did she sleep here last night?

...Not that it really mattered, and she had cleaned up neatly before leaving.

Anyway, I tossed the bag of Eve Secret lingerie I had brought home to study onto my bed, changed my clothes, and headed back to Seo-hye's apartment.

.

.

.

Back at Seo-hye's place.

Seo-hye, wearing an apron over her office wear, had placed two toasts on the table.

"Perfect timing. You can eat before we go."

Seo-hye smiled warmly.

She was beautiful.

Was this the honeymoon phase? She didn't look particularly different, yet she seemed so much prettier...

At the same time, my dick throbbed.

Once the morning passed, who knew when I'd get another chance to have sex with her?

Should I just confess and ask her to be my girlfriend?

...Or, taking advantage of yesterday's lingering vibe, should I just lift her skirt, pull her panties aside, and shove it right in?

"Dohyuk. Why are you licking your lips like that? You're going to drool. Hurry up and eat."

"Huh? Oh, right..."

No bad thoughts.

I felt like my mind was slowly rotting ever since I started working at this company full of sluts, but hadn't I dreamed of romance?

I cleared my head.

Then, I took a bite of the toast.

It was filled with shredded cabbage mixed ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠with egg wash, fried, sprinkled with sugar and ketchup, and sandwiched between bread.

The kind of taste that felt like it would spike my blood sugar first thing in the morning.

It left a little to be desired...

But it was still delicious.

"...How is it?"

"It's good. Make it for me again sometime."

Honestly, toast was just toast.

The giant toast sold by the ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠old lady downtown tasted better.

My question was more about whether we could ever be in a situation like this again.

Seo-hye smiled brightly.

"Hmm... Let me know if you want some. I'll bring it to the office. I should make some for Assistant Manager Lee too."

"Ah... Yeah. She'll love it."

I couldn't hide the disappointment that crept onto my face.

"Oh, and Dohyuk."

"Yeah?"

"About yesterday... we're young! I think these things can happen! We had drinks too!"

"What do you mean?"

"You know... the sex... let's just think of it as a one-time thing! I mean, you weren't thinking of us dating or anything, right?"

"Ah... Of course not."

Tsk.

...How bitter.

How could she speak so coldly after enjoying it so much yesterday?

Judging by the lack of malice on her face, she seemed worried that taking the relationship further would cause awkwardness.

There was no way she didn't like the taste of my dick.

Was it just a one-night stand kind of vibe?

Well, we used a condom, so there was no need to worry about pregnancy.

Unaware of my inner turmoil, Seo-hye asked, "Do you want some coffee?"

"Yeah..."

She wiggled her plump ass as she walked over to the coffee machine.

A one-night stand... I guess that's not bad.

But the human heart doesn't always listen to reason!

Although the memory of having sex with Seo-hye wouldn't leave my head, it wasn't enough to disrupt my work life.

Besides, perhaps because of the presentation preparation period, no one at the company did anything too bizarre to me.

By "bizarre," I meant using a male employee to "test" their products.

Fortunately, they didn't seem to do it every day.

However, there were a few people who showed an unusual amount of interest in me.

Out of nowhere, Development Team 3 Leader Kim Inyoung said, "Dohyuk, you look busy today. Take it easy... Touching my breasts will cheer you up. Want some healing?"—uttering one of the most slutty lines in history.

When I went to the administration office to copy some documents, Finance Team Section Chief Song Juhee, dressed in a clean, all-white suit, held my hand under the guise of teaching me how to use the copier.

The instructions are literally written right on the copier. Why...?

She even pressed her body close to mine to adjust my tie, claiming it was crooked.

It was a zipper tie that you just pull to tighten. Why go through all that trouble...?

Furthermore, PR Team Leader Han Seah, who came all the way from the PR department to the Support Team, got into a heated argument with my manager, demanding to "borrow" me for a business trip down south.

I mean, a business trip for a brand-new recruit who just joined the company? That makes no sense...

The final blow in all this chaos came from Design Team Leader Mo Haewon, who was practically the company's mascot.

She was somewhat cute, but the words that came out of her mouth were: "Dohyuk, I'm designing men's underwear and I want to use you as a fitting model. Can I measure your dick?" She thrust a tape measure at me, and when I gasped in horror, she claimed it was just a joke.

...Having already gone through that sticky initiation on my first day, I wasn't too shocked, but I wrote their names down in my "Slut Notebook."

My prediction was somewhat accurate.

It was chilling to spot the four of them having coffee together in the afternoon.

According to Assistant Manager Lee Yena, who was with me at the time, they were the infamous "Four Princesses Faction."

"Phew... That's dangerous."

If there was any consolation, it was chatting with Seo-hye in the pantry.

Although her drawing a line between us felt a bit disappointing, what could I do...?

I was just grateful to have finished another day of work safely.

Or so ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠I thought, until I returned home after work.

And found my younger sister, Cha Dohui, waiting for me in my room, wearing nothing but her underwear.
