I Want to Build a Harem
I want to build a harem.
After Kim Iseo left and I finished cleaning up, I checked the clock—somehow it was already 11:50. Heading to the cafeteria for lunch right now would put me at an awkward time.
It wasn't like there was some rule that said you had to finish eating before lunch period started, but…
The place gets way too crowded.
I'd been working at Saewa High for a full month now, so the students from our school barely paid me any attention when I walked the halls. The cafeteria was a different story.
It was a shared space with Saewa Girls' High next door, so if I showed up during the students' lunch rush I often ran into girls from the other school who wanted autographs or photos. Eating in peace was nearly impossible.
I'll just grab some bread from the school store.
I stepped into the store inside the school building and locked eyes with the part-timer.

"Oh, Oppa! You didn't eat in the cafeteria today?"
"Ah, yeah… just wasn't really feeling it."
The girl who greeted me the moment she saw me, smiling brightly and full of warmth, was Seo Na-rin, the school-store part-timer.
Back when I was a student, the store was usually run by the owner lady herself at the counter. These days they hired part-timers through CarrotApp.
The reason a part-timer who'd only been working a month greeted a public-service worker like me so cheerfully wasn't just because she was naturally kind—Seo Na-rin was my fan.
And not some casual light fan either. She was a hardcore one who'd come to matches in person and attended fan meetings and signings.
After exchanging greetings with Na-rin, I picked up the chocolate roll bread and white milk I usually got and set them on the counter.
Beep-beep—
Seo Na-rin rang me up with practiced ease, then set a cola-flavored stick candy next to the bread as she spoke. It was the candy I'd loved during my pro days—something the school store didn't even sell.
"This is a gift!"
"Uh…? You really don't have to give me stuff like this…"
Honestly it made me happy, but I wasn't used to receiving unconditional kindness, so I said something half-hearted. Seo Na-rin just smiled at me with that warm, sunny expression.
"Come on—it's from a fan, so just take it, Oppa~"
"Ah… yeah. Thanks—"
In that exact moment I felt someone's hand lightly grab my butt. I didn't even need to turn my head—the familiar touch told me exactly who it was.
"What are you two? What's going on here?"
I looked over at the voice and found Lee Su-a staring back and forth between me and Seo Na-rin with her eyes wide. While I stood there too startled by the sudden appearance to say anything, Seo Na-rin explained in my place.
"Ah, I'm Jinwoo-oppa's fan!"
Lee Su-a lightly pinched my cheek and gave me a smiling look.
"Oppa? Our Jjinu's gotten pretty popular while I wasn't looking, huh?"
"Um… Oppa looks like he's in a little pain…"
At that, Lee Su-a shot Seo Na-rin a sidelong glance, then reacted a bit more strongly than usual.
"Ah, it's fine. Jjinu and I always play around like this. You can worry because you're a fan, but you're being a little nosy. Right, Jjinu~?"
What is this…? Is this what jealousy looks like?
"Y-yeah—I'm fine, so don't worry about it."
My answer must have satisfied her, because Lee Su-a laughed and lightly smacked my butt a couple of times.
"If you're done shopping, let's go."
"Y-yeah…"
Seo Na-rin waved at me as Lee Su-a dragged me away. For some reason Na-rin's cheeks looked a little puffier than usual.
"Oppa, come again next time!"
"Yeah—see you later."
As we left the store and naturally started walking the hallway together, Lee Su-a asked,
"Jjinu, why didn't you come to the cafeteria for lunch? I asked Hae-rin and she said she sent you off to eat ages ago—"
I couldn't exactly say I'd been with Kim Iseo, so I waved the chocolate bread in my hand and made something up on the spot.
"Huh…? Ah, I suddenly got a craving for bread, ahaha…"
Lee Su-a's eyes narrowed suspiciously.
"Youuu—you didn't go just to see the store part-timer, did you? You two looked pretty close—"
Even someone as clueless about women as me could tell from the way she'd treated Na-rin earlier that this was definitely jealousy. Once again I felt certain my suspicion that Lee Su-a liked me wasn't just a delusion.
Up until yesterday I'd planned to ask her about those feelings if we ever ended up alone like this, but…
Right now Kim Iseo was weighing on my mind.
How could she not? Only a few dozen minutes ago I'd been getting a handjob from Kim Iseo and felt the most electrifying pleasure of my life. Sure, you could argue I'd been half-forced into it… but thinking back on yesterday, it wasn't like I was completely free of responsibility either.
That was secondary, though. The real problem was that choosing between Kim Iseo and Lee Su-a wasn't easy. If I poked at her feelings now and Lee Su-a actually confessed, the choice would be forced on me.
Is this why the male leads in romantic comedies always act so indecisive and frustrating? Haah, deciding who to pick between the two is seriously hard.
Honestly both of them were so attractive that if I had my way I'd date them both at the same time… but unlike manga or anime, there was no way a harem could exist in real life.
But I still want to build one. A harem.
Anyway, I decided to put testing Lee Su-a's feelings on hold and changed the subject.
"So what's up? From the way you asked Kang Hae-rin, it sounds like you were looking for me…"
Lee Su-a suddenly linked arms with me and pressed her body against mine with a meaningful smile. She was wearing her white nurse's coat over her blouse, but her chest was so massive that the heavy, soft sensation still came through clearly where it touched me.
"Jjinu, help me out a little~ I have to do water-quality tests on the water purifiers and drinking fountains today, but I've got other stuff so I don't think I'll have time—"
"Huh? But I don't know how to do any of that…"
"Ah, don't worry about that! An expert's coming to the school after lunch. You just have to follow him around and watch what he does!"
If it was just watching, I could help—but thinking about how many purifiers and fountains the school had, this wasn't going to be a quick job. That meant I'd be away from my desk in the Main Staff Office for a long time… and in that case I absolutely needed permission from my supervisor, Kang Hae-rin.
Just imagining Kang Hae-rin staring at me with those cold eyes while I still had my arm linked with Su-a sent a chill down my spine.
"If you talk to Kang Hae-rin, I'll help."
"Heheh~ I already told her, Jjinu~"
Whew…
If she'd already gotten Kang Hae-rin's permission, I never really had a choice to begin with. The reason she'd still asked me…
Did she just want to see how I'd react when she asked for a favor?
Anyway, this job somehow smelled like pure easy money. All I had to do was follow the expert around without any other work.
Don't tell me she deliberately gave me this job to make things easy for me?
Thinking that Lee Su-a liked me made that possibility feel entirely plausible.
"Thank you for your hard work. Please get home safely."
There were over twenty water purifiers in the school alone, so the water-quality inspection took more than four hours. I saw the hardworking expert off.
Just as Lee Su-a had said, the inspection only required following the expert around. The time dragged a bit, but I would have been doing other work during those hours anyway, so it turned out to be a pretty comfortable stretch exactly as expected.
It was already 4 p.m. Official quitting time was 6, but after 4 most teachers without after-school duties headed home, so there was almost never any work left. That meant from now on I could just sit at my desk in the nearly empty Main Staff Office and kill time.
This afternoon basically felt like free money. Thanks, Lee Su-a.
Feeling grateful toward her, I sat down and was about to open the mobile game I'd gotten into lately… when Kim Iseo, who should have left ages ago, stood up from her seat with slightly flushed cheeks and walked over to me.
"Hey, Jinwoo. Follow me."
"Huh…?"
"Ah, hurry up!"
Unable to resist Kim Iseo's urging, I stepped out of the Main Staff Office—only to run straight into Lee Su-a walking toward us with a paper carrier of coffee.
"Oh, whaaat—where are you two going?"
"We've got work, so mind your own business."
Kim Iseo answered more sharply than usual and tried to keep walking.
"Whaaat—why's our Iseo so mad—did Jjinu do something wrong?"
But Lee Su-a blocked her path with a bright grin.
"It's not like that. I'm busy, so move."
"Okay~ just a sec. Jjinu, good work today—this is your reward!"
I awkwardly accepted the paper carrier she held out and thanked her. Inside were iced coffee and some baked snacks.
"Uh…? Thanks. I was just doing my job…"
Then Lee Su-a, making sure Kim Iseo could see, lightly squeezed my butt and whispered to me.
"Jjinu~ even if Iseo bullies you, hang in there! Fighting~"
Looking at Kim Iseo's furrowed brow as she watched us, I got the distinct feeling the two of them were sparring.
"Hey, hurry up! If we want to finish before quitting time we have to move. Su-a, stop bothering us and go already."
And so, for the second day in a row, I found myself back in the Gymnasium Equipment Room. The moment we arrived Kim Iseo locked the door and pinned me against the wall just like yesterday.
"Hey. You looked pretty happy earlier."
"Huh…?"
"What did I tell you at lunch today?"
Hearing Kim Iseo bring up lunchtime, honestly nothing else came to mind except the handjob. The first handjob of my life. Just remembering it made the corners of my mouth threaten to twitch upward. Kim Iseo raised an eyebrow at me.
"You're smiling?"
Ah.
"I said you're my toy. So from now on, tell Lee Su-a to stop touching your butt."
Out of nowhere…? Wait, more importantly, I did say I was her toy, but I don't think I meant it with that kind of nuance…
Unless I'd already decided to choose Kim Iseo, this felt like an excessive demand, so I decided to refuse. Of course, an angry Kim Iseo was a little scary, so I shrank back slightly as I spoke…
"Ah, that's a bit…"
"In exchange, from now on I'll make you feel way better than that."
The moment she finished speaking, Kim Iseo suddenly unzipped her top. From the way she'd dragged me here, this had clearly been the plan all along—under the open zipper there wasn't a single scrap of clothing.
Holy shit…
Faced with the pure white, beautiful expanse of flesh right in front of me, something as trivial as a butt squeeze suddenly felt completely meaningless. My head was nodding before I even realized it.
Then Kim Iseo began stripping off my lower clothes with a now-familiar touch. My cock was once again exposed right in front of her eyes. The corner of her mouth lifted slightly as she looked at it, and she pointed to a nearby box.
Gulp…!
"Hey. Sit over there."
"Y-yeah…!"
I sat down full of anticipation. Kim Iseo, her earlobes faintly red, knelt in front of me and sandwiched my cock between those overwhelming breasts.

H-holy shit! After the handjob she's giving me a paizuri too…?
