A Heart That Changes Bit by Bit
After we finished and I’d even taken a shower, I came back home and deleted the photos right in front of Seong Miyeon.
“...They’re really all gone now?”
“You watched me do it. I emptied everything.”
Even though I was the one deleting them, I felt a twinge of regret. Some of the shots had turned out pretty well.
“If you made any backups or anything…”
“I didn’t do that.”
A promise made is a promise kept. Besides, I had no use for them anymore.
The Fourth Skill effect had already worn off. They couldn’t be used for blackmail anymore.
Well, I can always take new ones later.
Once you’ve done it once, the second time isn’t exactly difficult. Next time I’ll dress her up as a bunny girl and take even better pictures.
“Hmm.”

Even though she had gotten exactly what she wanted, Seong Miyeon wore a strange expression. She must have realized, a little too late, that I hadn’t needed to go this far. Now that the fear was gone, she probably felt like she had come out at a loss.
“Anyway, good. If these ever appear in front of my eyes again, you’re really dead, got it?”
“Don’t worry. I really didn’t make any backups.”
“Obviously you shouldn’t have. After all the trouble I went through?”
She had worn cat ears and a collar and serviced me; she had every right to say that. Still, for someone who claimed it was such a hardship…
“You seemed to enjoy it quite a bit too, didn’t you?”
“...What?”
“The way you were shaking your ass, it looked like you were really—”
Smack!
Seong Miyeon lightly whacked me on the head.
“Is there anything you won’t say to a girl?”
It was the first time Seong Miyeon had ever hit me. Hmm. It didn’t feel that bad. Maybe because a beautiful woman did it. Or maybe because I had deserved it.
“You’re the one who begged me to do it. Who the hell enjoyed it?”
“Really?”
“...Of course. Haven’t you watched too much porn?”
Seong Miyeon crossed her arms and spoke with a prim expression.
“All of that was just acting. You kept pushing, so I threw you a bone to keep you satisfied.”
No matter how I thought about it, she had definitely enjoyed herself. Her completely melted face had shaken her hips with real enthusiasm. The sound of our bodies slapping together had been insane.
If that was acting, she should’ve become an actress instead of a model. Though with that face, she probably would’ve succeeded at that too.
Anyway, I decided to let it slide. Making Seong Miyeon admit the truth someday sounded like fun.
“Sigh. I can’t believe I’m doing this with a pervert like you.”
“Just so we’re clear, I wasn’t the one who suggested it. You came to me first.”
“...I know. I still don’t understand why I did that.”
Why? Because of my Pregnancy Skill, obviously. Seong Miyeon would never guess it, but she was slowly being tamed by me.
Cat ears and cowgirl sex? The old Seong Miyeon would have rather died than do something like that.
It means her resistance is weakening and she’s getting used to having sex with me.
Once her threshold drops, she’ll accept even more extreme things without complaint. As expected, the Pregnancy Skill is the strongest. To think I could train this arrogant bully to my tastes.
“...Why are you talking so strangely?”
“Huh?”
Seong Miyeon, who had been lost in thought, looked at me. Her eyes weren’t as fierce as before. If anything, they looked… a little hurt?
“You got hard and did all sorts of things because it felt good for you too. Why are you talking like only I enjoyed it?”
“No, of course it felt good for me. Do I even need to say that?”
“...Really?”
“When I look at your breasts and ass, any man would lose his mind.”
The way her heavy breasts bounced during cowgirl had been breathtaking. I kept thinking, so they can really shake like that.
And it wasn’t just her body.
When she smiled, the whole area seemed to brighten. And the way her ass felt… Every time she bounced on me I thought my dick was going to melt.
“If I can do it with you, I’m always down. This time included.”
“...Hmph. Good to know.”
Seong Miyeon’s face turned red. In the past she would have gotten angry. This was another meaningful change.
“Ahem! Ahem! So you should be grateful. It’s not easy to hold a beauty like me.”
“I know, I know. Come whenever you want, as long as you feel like it.”
“Bullshit. Come again? As if.”
Seong Miyeon glanced down at my lower body. Her throat moved as she swallowed.
“Ah, not right now. We went at it for too long and I’m tired too. I have class.”
“W-who said I wanted to?!”
Seong Miyeon suddenly raised her voice.
“Just because your dick is a little big you’ve gotten so cocky.”
“It’s not exactly ‘a little,’ is it?”
“Is that what’s important right now?”
To a man, it’s actually pretty important. Pride is on the line.
“If you want it again, you should be the one begging. Why should I beg?”
“If I asked, would you do it?”
“Hearing you say that just now made me not want it anymore.”
As expected of Seong Miyeon. She would rather die than throw away her pride. We had already had enthusiastic sex three times. She had done a bikini photoshoot and cat cosplay, yet her will was still this strong.
...Saying it out loud made me realize I sounded like trash.
“Ugh. Now that I think about it, this is ridiculous. Why am I rolling around with a guy who never even confessed to me?”
She talked as if she would accept a confession. She would probably reject me immediately anyway.
“Speaking of which, why do you act so high and mighty as a guy?”
“Me?”
“Every time we have sex I practically have to beg and beg before you’ll do it once.”
...Now that she mentioned it, that was true. But that had been necessary for her training. I had to break down Seong Miyeon’s personality a bit. Even now she had become much easier to deal with. I no longer had to threaten or blackmail her like before.
“Don’t guys usually beg to have sex first?”
“That depends on the situation.”
“Ha. So you’re saying I’m in the position where I have to beg you for sex?”
Well… honestly, wasn’t that accurate? She had been so horny she couldn’t stand it and came all the way to my house.
“This is unfair. Next time you have to beg. Understand?”
“Huh? I deleted the photos, but you still want to do it with me again?”
When I asked casually, Seong Miyeon’s face flushed bright red like a tomato.
“I don’t know! I’m leaving!”
Seong Miyeon turned away. She seemed eager to escape the situation as quickly as possible.
“Ah, Miyeon.”
“...What?”
But when I called her, she stopped in her tracks and turned around. Obedience had already been imprinted into her subconscious.
“After class, let’s meet up and work on the assignment together.”
“Weren’t you supposed to take care of that?”
You shameless woman. You were the one who pushed it onto me. When did I ever say I would handle it alone?
Since I would be fucking her regularly from now on, I let it slide.
“The more I thought about it, the more it seemed like we should do it together.”
“Hmm.”
“It’s a paired assignment. We should meet at least once.”
“...Fine. Can’t be helped.”
Seong Miyeon nodded in agreement, opened the door, and left. She had folded so easily. The Pregnancy Skill really was working properly.
“Kyah~ Nice. So nice.”
These days of having sex with Seong Miyeon. It wouldn’t be an exaggeration to call them the best of my life. There was one more thing that had me looking forward to the future.
Impregnating a new skill!
Incubation period: 24 hours.
A skill that required a full 24 hours of incubation. It was the longest period yet.
“Does that mean the skill that comes out will be that good?”
I wondered what kind of skill I would use to train her next. I never thought I would be thinking like this. I was already dying for the next birth.
****
After meeting Seong Miyeon, my university life was… surprisingly unchanged!
Well, I guess that makes sense.
The fact that Seong Miyeon and I were having sex was obviously a secret. We weren’t dating, and it wasn’t something I could brag about anyway.
Seong Miyeon is popular and successful, so having her feels even better.
In the end, Seong Miyeon was still the same arrogant bully, and I remained a nobody. Ah, so this is the life of an outcast.
Thinking that sleeping with a girl would change anything is probably the most outcast thing about me.
No. I’m not wrong. A student’s duty is studying. Today the professor praised me again. That beautiful, large-breasted blonde professor who studied abroad in the US.
“Jihun, you know this too? You’re really working hard~”
Just hearing her say that gave me strength.
Anyway, class ended like that.
“Yawn~”
It was still daytime, yet I was already yawning. Well, I had gone pretty hard with Seong Miyeon. Maybe I should start working out? My stamina seemed to be dropping even if my virility wasn’t.
Anyway, I should go work on that assignment soon.
Seong Miyeon was still chatting with her friends. They were gathered in a group, laughing loudly about who-knows-what. It was the perfect picture of a female bully clique. The girls with her were all models, of course. None reached Seong Miyeon’s level, but every one of them was beautiful enough to dominate any room with their faces alone. A loner like me felt like slime just looking at them.
“Hoo.”
But who was I? I was Kim Jihun. The man who had done cosplay sex with Seong Miyeon. I couldn’t keep living as a coward who only watched from the sidelines.
“Miyeon.”
“Yeah?”
When I called her name she whipped her head around. Her sharp eyes looked fierce for a moment, but softened the instant she confirmed it was me.
“Ah, the assignment?”
“We agreed to work on it.”
“...I’m a little busy right now.”
“So you’re saying you won’t do it?”
“Ugh, fine. Let’s go.”
When I asked sullenly, she eventually nodded. Busy, my ass. I had heard her talking about which café to go to earlier.
While I waited, the girls stared at me with surprised eyes.
“Um… Miyeon.”
“Yeah?”
“Are you close with Jihun?”
“...No. We’re just in the same class.”
“Ah… I see.”
They kept sneaking glances. They were all looking at me like I was some exotic animal. Was it really that surprising that I was doing an assignment with Seong Miyeon? Honestly, even I found it surprising.
“Now that I think about it, there was that rumor about you two…”
“Hey, I told you that was a joke.”
“Ahaha… Right, right.”
A strange awkwardness lingered between them. Why were they acting like that? It wasn’t weird for college students to work on an assignment together.
“Still, it’s pretty surprising.”
“What is?”
“You don’t really like guys, Miyeon.”
“Kim Jihun is an exception.”
Seong Miyeon must have realized how that sounded, because she quickly added,
“He’s comfortable to be around. He’s the top student in the design department, so it’s good to be friendly with him.”
“Ah~ So that’s why? Now that I think about it, you did that event together last year too.”
“We’ll be doing it again this year. Don’t even think about trying to steal him.”
Seong Miyeon answered as coolly as she could and stood up from her seat.
“That’s enough. Let’s go.”
“Ah, okay.”
We walked out of the lecture room side by side. Maybe because I had overheard the whole conversation, the atmosphere felt strangely awkward.
Actually, there was something that bothered me more.
“You’re really going to do the event with me again this year?”
It was an assignment where one student from the modeling department and one from the design department paired up. The weight of the grade was significant, so it was a fairly important event.
“Obviously. For something like this, the top students should team up.”
Why was she deciding that on her own? When I looked slightly dumbfounded, Seong Miyeon narrowed her eyes.
“What? You don’t want to? After you took my virginity, you’re going to throw me away?”
“Hey, hey. The way you say that sounds weird.”
“What’s weird about it? It’s the truth.”
“No, we’re not even dating—ow!”
Seong Miyeon kicked my thigh.
“Seriously, every single thing you say pisses me off.”
“...That hurt.”
“Deal with it. It’s a reward.”
How could being hit be considered a reward…? Though with someone like Seong Miyeon, there were probably guys who would want to be hit by her.
“Anyway, why are you playing so hard to get? It would be good for you to work with me too.”
“Hmm…”
It was true that Seong Miyeon had both great style and overflowing charm. Anything she wore looked amazing. As the design partner, she was an excellent choice. If only she didn’t have that nasty pride and perfectionism.
Last year had been such a struggle because of that.
“...What? Were you planning to do it with someone else?”
Seong Miyeon’s eyes flashed dangerously. If I answered wrong, it looked like she would tear me apart. We had even had sex together—why was she still this scary? Shouldn’t I be more comfortable with her by now?
“I wasn’t thinking of doing it with anyone in particular.”
“Hmph. Of course you weren’t.”
Only after hearing my answer did she smile with satisfaction.
“There’s no way our little outcast would have any other woman besides me to work with.”
“Then why are you the one deciding that?”
“What, do you have someone? If you have even one girl you talk to, I’ll admit it.”
“...I don’t.”
What a cheap shot, attacking with cold hard facts. It wasn’t an arrow—it was a siege weapon bombing an outcast’s heart.
“But you’re the top student. How do you not have even one girl you talk to?”
“Of course I do in the design department. Just not in the modeling department.”
Although the modeling and design departments had merged, they didn’t exactly feel close. The modeling department was full of popular, attractive people. Especially between men and women… yeah, no comment. As a result, I barely knew anyone in the modeling department.
“You really don’t have anyone? You’re not hiding something from me?”
“Look at my face. Does it look like I would?”
“Hmm~ It’s not that bad, actually.”
“Oh my. Thank you so much.”
Now that we had gotten closer, it seemed she was willing to give me some compliments.
“If you work out hard and dress in my style… hmm…”
Seong Miyeon stroked her chin and nodded to herself. It was a little scary.
“But do you really have a reason to do it with me? There are plenty of skilled seniors.”
“I feel uncomfortable with seniors. You’re much better.”
In other words, she wanted a slave she could order around however she liked. Even Seong Miyeon probably found it difficult to boss actual seniors around.
“You don’t like seniors either, right?”
“I don’t particularly dislike the seniors, but…”
“Hmm?”
“...They’re fine, but I’m more comfortable with someone from the same year.”
“Yeah, that’s how it should be.”
She was treating me the same way she would a senior. Looked like I was destined to be her slave again this year.
“Hey, you should be grateful I’m offering. Even if you combined all the seniors, none of them are a better model than me.”
As expected of Seong Miyeon. Her confidence was incredible. It wasn’t like she knew everyone in every department.
“...Then what about the underclassmen?”
“I don’t know them well. Their skills as freshmen are all about the same anyway.”
“You were a freshman just a year ago.”
“Do I look like an average freshman?”
“Your confidence is insane.”
Well, that was true. Seong Miyeon had been devouring everyone since the beginning. Her face and body were simply on another level.
“You don’t know the underclassmen either. Have you ever even talked to a first-year in our department?”
“Are you subtly insulting me again?”
“But it’s a fact, right?”
Ugh! It was. The freshmen were busy getting to know each other. There was no reason for them to bother with an outcast like me…
“Ah, there is one girl who sometimes greets me.”
“...Huh? Who?”
“Baek Seohee.”
“What the fuck did you just say?”
Killing intent poured from Seong Miyeon’s eyes.

...I should have just kept my mouth shut.
