"Don't get angry. Just keep doing what you were doing."
"Got it... mmm...!"
At my words, Han Yugyeong went back to sucking my balls into her mouth and rolling them around with her tongue just like before. My cock was still rock hard—in fact, it had gotten even stiffer under Ha Juyun's gaze—so there was no need for her to warm me up.
She seemed to sense that too. After licking my balls for a while, she started running her tongue along the shaft. While licking the thick vein protruding from the underside, she opened her mouth.
"Slurp...! Mmm, it's so hard and hot."
She was licking me diligently while still giving her impressions. It was so cute that I decided to return the favor. I slid my foot between her thighs as she knelt there sucking me and began rubbing her pussy with my big toe. She was still wearing panties, so I couldn't touch her directly, but her juices had already soaked through so thoroughly that I could feel every fold and contour against my toe.
"Haaang~!! Nooo, if you do that... mmm! I can't concentrate on sucking Yongtae's cock~♥"
Han Yugyeong whined as if pleasuring me should come before her own pleasure. That only made her look more adorable, so I tormented her pussy even more with my toe.
"Haa! Haang♥ Mmm...! It feels so good, Yongtae... ahhh♥"
Her pussy was already dripping wet, completely soaked with arousal. The more I rubbed her through the increasingly slippery fabric, the more desperate her expression became. My skillful toe work quickly brought her to the edge.
"Mmm...! Haang! I'm gonna cum!!"
As I kept rubbing, her juices splattered onto the floor. Her legs gave out and she dropped her ass to the ground.
"Haa... haat... I came. Yongtae, you're so mean. I was trying to make you feel good!"
"Hahaha, you can still do that now, can't you?"
Her pouty complaint was so cute that I couldn't help laughing. She nodded at my words and spoke.
"No touching while I do it this time, okay?"
"Sure. I'll stay still."
Han Yugyeong opened her mouth wide and swallowed my cockhead. She sucked hard on the glans while her tongue never stopped its enthusiastic licking. She hadn't been this skilled before. It looked like she'd been practicing with something like a banana. As expected from a good student—she prepared and reviewed thoroughly.
"Ugh! That feels amazing."
When I unconsciously bucked my hips while she sucked me, she looked satisfied. Even with my cock in her mouth, her eyes curved into crescents as she smiled. That eye smile was incredibly sexy. Just seeing her face made me even hornier.
Slurp, slurp, slurp!
When she saw how much I was enjoying it, she got more excited. She started bobbing her head back and forth, sucking my cock greedily. I couldn't hold back against her technique. I felt my cum rising from my balls.
"Huk, I'm cumming... ugh...!"
Spurt! Spurt! Spurt!
My cock pulsed powerfully, shooting thick ropes of semen. Han Yugyeong swallowed repeatedly, her throat working to take every drop. There was quite a lot, but she drank it all. It was honestly impressive.
"Hehe, I ate it all. Did I do good?"
"It doesn't taste bad?"
"I've never tasted anyone else's, so I don't know how yours compares, but I think it's fine to eat."
After saying something completely adorable about never having tasted another man's cum, Han Yugyeong stood up and headed for the bathroom.
"Let's wash up first."
"Sounds good. We did sweat a bit..."
We'd mostly been in the car on the way here, but the weather was hot, so we'd sweated a little whenever we were outside. If I hadn't just cum, I might have gone straight to the next round, but since I'd just finished, I still had enough sense to agree to clean up.
"I'll wash first."
"Huh? I was thinking we could shower together..."
When she said she'd wash first, I complained a little, hinting that I wanted to join her. But Han Yugyeong gave me a look like an older sister scolding her little brother.
"I have something prepared. I'll wash first, and while you're washing, I'll get it ready."
Ah, so she had some kind of event planned. Once I understood, she gave me quick kisses on both cheeks and disappeared into the shower. While she was washing, I sat on the sofa checking my phone when a KakaoTalk message arrived from Ha Juyun, whose number we'd just exchanged.
So it was decided for tomorrow after all. Shouldn't she have asked Han Yugyeong about this? Ha Juyun really did whatever she wanted. Still, I'd agreed to help for a day, so helping tomorrow would be fine. But what kind of reward? Maybe she'd buy me something delicious?
The singer we were filming the music video for was a ballad artist named An Ha-yeon. When I searched, it said her album would drop in five days. Filming the MV the day before release? That seemed way too late. Curious, I'd messaged Ha Juyun.
It turned out the world I was in was more advanced than the one I'd originally lived in. It wasn't that far in the future, but things like this still sometimes went way beyond my common sense.
Plus, information about AI video editing wasn't even in the original game, so it felt fresh and interesting. While chatting with Ha Juyun, the bathroom door opened. I wrapped up the conversation and looked at Han Yugyeong.
"I'm done washing. Yongtae~! Your turn to wash up!"
"Okay, I'll go wash."
She came out with a large towel wrapped around her body and another around her hair, then spoke to me. I went to the room where I'd left my suitcase, grabbed a change of underwear, and headed to the bathroom.
Shaaaa!
As the shower water poured over me, I wondered what Han Yugyeong was preparing. She was probably getting ready in some sexy lingerie... I was secretly looking forward to it. If I washed too quickly, she might not have enough time to get ready, so I took my time before stepping out.
"Yugyeong..."
Han Yugyeong stood before me with a slightly flushed face. She was wearing a school uniform. A white blouse with a necktie, a black pleated skirt, black stockings, and even dress shoes. She'd been waiting for me dressed like that. The style was different from the Japanese school uniforms you usually saw, which only made me more excited.

"This is the uniform I wore in high school..."
This seductive woman...! She was clearly trying to drain every last drop of cum from me. I couldn't hold back anymore and rushed toward her. She lightly dodged my hands, gave me a bewitching smile, and asked.
"Hehe, do you like it?"
"Yeah, it's incredibly sexy and pretty!"
"Really? I'm glad."
Like a skilled matador, Han Yugyeong toyed with me as I charged at her aggressively, only making me want her more.
"Since I'm already dressed like this... should we do a little roleplay?"
Roleplay? She'd obviously be the student. What would I be?
"What should I do?"
"Hmm... Yongtae, you can be my tutor. Our family was poor when I was in high school, so I couldn't go to academies or get private lessons. I want you to be my first tutor♥"
Did she develop this fetish because she was poor during her school days? Or did she just like roleplay? Either way, I nodded and agreed to become Han Yugyeong's first and last tutor. Come to think of it, it was funny. With my intelligence stat at 4, I was supposed to teach someone with 15 intelligence.
I put my clothes back on, grabbed a notebook, and went to the room where Han Yugyeong was waiting. When I entered, she smiled and greeted me.
"Hello, sir! You're a little late today, aren't you?"
"Uh, sorry. The bus was late..."
I played the role of a nerdy engineering student who had zero immunity to girls. Sitting beside Han Yugyeong, I looked at the test paper in front of her. Hmm... I had no idea what any of it meant. Of course just pretending to be a tutor didn't actually make me smarter. To my eyes it was just white paper with black writing.
"I finished all my homework, teacher. Could you check it?"
"Yeah, if it's Yugyeong, I'm sure you got everything right. Good job..."
I tried my best to channel the awkward engineering nerd, my hands trembling slightly as I patted her head. When I stroked her hair, Han Yugyeong unconsciously let out a moan of pleasure.
"Haaang!!"
"W-what's wrong?"
"Nothing! It's just that your touch feels so good, teacher..."
"Ah! Sorry... Did I touch you for too long?"
Surprisingly, I seemed to be pretty good at acting for a roleplay. Maybe because Han Yugyeong was the daughter of an actress, her performance was excellent. It was funny to judge myself, but I didn't think I was half bad either.
"Then could you watch me solve these problems?"
"Sure, go ahead..."
Since I'd brought a notebook with solutions and answers, I could at least tell if what she was solving was correct or not. When had she prepared all this? Oh, right! She was already working as a tutor, so she must have used her own materials.
"Yes, this is good. This one is wrong... 95 points! Your skills are improving. Well done, Yugyeong."
"Hehe, it's all because of the promise you made, teacher."
When I asked what she meant, Han Yugyeong puffed out her cheeks in a pout. She looked exactly like a sulky high school girl. I almost kissed her without thinking. This roleplay was surprisingly arousing... My cock was already straining so obviously against my pants that it was a little embarrassing.
"You promised that if I scored over 90 on the monthly tests, you'd grant me one wish~!"
"Ah, right. I did say that. W-what's your request?"
At my question, Han Yugyeong stood up, walked to the door, and locked it. Then she went to the bed and lay down. Still lying there, she gave me a seductive smile and spoke.

"Please turn me into a woman, teach-er♥"
You're already an insanely hot woman... I didn't need to say that thought out loud. I kept my acting face until the very end as I approached Han Yugyeong.
The Han Yugyeong school uniform images I made but ultimately rejected.

I originally made the bare-leg version first.

Wow, bare legs look pretty good too.

I also made a version with the school blazer, but since it's set in summer...

There was an illustration with the blazer for the black stockings version too, but it was rejected for the same reason.

The bed was too small so it got rejected. The white socks with the black stockings version was actually pretty nice lol.
