Why Are You So Good at This, You Jerk?
Nayeon must have assumed that I would be flustered and scrambling around like a headless chicken since it was my first time seeing women's underwear. She giggled, casting sidelong glances at me from behind her back.
I was certainly flustered, but it wasn't as if I had never seen women's lingerie before.
Whenever my younger sister overslept and was in danger of being late for school, I would often help her get ready, and it was quite common for me to help her put on her clothes as well.
Naturally, there were many times I had to help her with her undergarments, so I had learned exactly how to do it from her directly.
Though I felt a bit awkward, I didn't panic. I calmly fastened the hook behind her back, adjusting it to the right tightness with practiced ease.
Then, I pulled the shoulder straps taut over her collarbones and finished by using my hands to firmly sweep the side breast tissue inward, as if filling out the bra.
People often mock the cleavage created by bras, calling it "gathering it up from the soul," but in reality, pulling the flesh toward the center is the proper way to wear the garment.
Having learned these things from my sister years ago, I pulled it off calmly and without any major difficulty.
Contrary to her expectations, I didn't fumble at all. In less than fifteen seconds, I had perfectly put the underwear on her. Nayeon stared at me, jaw dropped, looking at me as if she couldn't believe her eyes.
"...W-what the hell, this is so f*cking annoying... Why are you so good at this, you jerk..."
"Eek... B-but you told me to do it..."
As I mumbled in my defense, Nayeon immediately narrowed her eyes, pouted her lips, and interrogated me as if she were sulking.
"...W-when did you learn how to do this...?"
"Uh... about three years ago...?"
I scratched my cheek, trying to recall when my sister had started wearing a bra, and gave her a rough answer.
Nayeon’s eyes went wide as she stared at me blankly. Then, looking as if she were filled with resentment, she gritted her teeth and grabbed my shoulders firmly.
"Ugh... Die, just die...!"
Nayeon was genuinely furious; she grabbed my shoulders and shook me violently back and forth.
I was so flustered that my face turned pale, and cold sweat began to trickle down.
Nayeon glared at me with a look so fierce it felt like she was going to eat me alive. Suddenly, she turned away coldly and put on an oversized white sweatshirt that had been hanging in the closet.
Then, she tied her hair up neatly with a hair tie that had been lying on the desk and pulled a white cap down low over her head.
Finally, fully prepared to go out, Nayeon turned back to me and spat out bluntly.
"...What are you doing? Let's go, hurry up."
"O-okay..."
Nayeon turned on her heel and walked out first, and I followed her cautiously.
Before long, we left the house and stood side by side in awkward silence in front of the elevator in the middle of the hallway.
After a brief, awkward silence, Nayeon glanced back at me and opened her mouth.
"...So, where are we going?"
"Et... I-I hadn't thought that far ahead..."
"What? No, so you told me to go out without even thinking about where we were going?"
Nayeon crossed her arms and glared at me. I was so flustered that my eyes darted around as I desperately tried to think of something.
'...I mean, you're the one who lives in this neighborhood, so you'd know better than me where to go... but if I say that, I'm a dead man, right? Besides, I'm just a shut-in loser anyway... How would I know what's fun to do outside...'
Just then, the elevator arrived on our floor with a ding. I jumped in surprise, flinching, and blurted out the first thing that came to mind.
"...S-shall we go to the playground?"
"Wha...?"
Nayeon raised her eyebrows in disbelief, her mouth hanging open as she stared straight at me. I was so nervous that I fidgeted with my fingers, anxiously watching her expression.
'...I guess it is ridiculous. Who goes to a playground at our age, like some elementary school kid... but that was all I could think of, what else was I supposed to do...'
The elevator doors slid open with a whir, but Nayeon just stood there, staring right through me. I was so terrified I felt like crying.
Just as I was about to give in to the pressure, kneel on the spot, and beg for forgiveness, Nayeon suddenly let out a soft laugh and shook her head. She uncrossed her arms and strode into the elevator.
Standing inside the elevator, Nayeon snapped at me as I stood there blankly watching her.
"...What are you doing? Are you not getting in?"
"Oh, right, I'm coming...!"
I scrambled into the elevator just before the doors closed.
Once we reached the first floor, Nayeon walked ahead without a word, her hands shoved deep into the front pocket of her sweatshirt.
I couldn't see her expression, so I couldn't tell if she was in a good mood or a bad one, so I followed her, feeling incredibly tense.
Before long, Nayeon began humming a completely off-key tune, looking up at the clear sky with a light step.
...Come to think of it, this was the first time since I started tutoring that I had been out like this with one of my students.
We usually only saw each other at home, so walking outside together felt a bit fresh. It was as if I were seeing a new side of Nayeon I hadn't known before.
Walking along happily under the bright sunlight, Nayeon looked a bit more cheerful and cuter than usual.
I let out a sigh of relief, thinking that Nayeon didn't seem to be in a bad mood.
When we finally arrived at the playground, Nayeon stopped in her tracks, spun around, and looked at me with her hands on her hips, smiling slyly.
"...Hey."
"Y-yes...?"
"Push me on the swings."
A moment later, Nayeon sat on the swing and looked back at me with a beaming smile.
'...Even my little sister graduated from being pushed on the swings when she was ten...'
I approached Nayeon hesitantly, placed my hands on her back—where I could feel her warm body heat—and gave her a very light push.
Naturally, while it might have been enough for a ten-year-old, that amount of force was nowhere near enough for a grown girl to have fun on a swing.
When the swing didn't move even an inch, Nayeon widened her eyes menacingly, turned her head slowly, and muttered.
"...What are you doing? Are you not going to do it right? Do you want me to break your fingers?"
"Y-yes, ma'am...!"
I was so chilled by the terrifying warning that I hurriedly put all my strength into pushing her back with my small hands, grunting with effort.
In the process, Nayeon arched her back like a bow, writhing and giggling.
"Ugh... That tickles...!"
Then, little by little, the swing began to move back and forth rhythmically, soaring higher and further each time.
Eventually, I didn't even need to use as much force as I had at the beginning; it began to rise and fall to great heights on its own.
It was enough to just give her bottom a light push with my hand every time the swing returned to my position.
"Ahahahaha! Aha! Ahahahaha!"
Nayeon laughed brightly and enjoyed the swing.
Watching her look just as happy as she did when she was a child, despite being long past the age for playing on swings, made me feel as if some warm, fuzzy memories were bubbling up in my own heart.
Before I knew it, I was pushing Nayeon’s swing with a bright smile on my face.
Nayeon laughed happily on the swing for a long time, then eventually dragged her feet on the ground to stop. She jumped off the swing, stood with her legs stretched out, and looked at me.
"I'll push you too, get on."
"Oh...? I-I'm fine..."
"Get on."
When Nayeon lowered her voice and threatened me while holding the swing chains, I reluctantly approached and sat down on the swing cautiously.
The swing was still warm from Nayeon’s body heat.
As soon as I sat down, Nayeon gave me a sly, wicked smile. Suddenly, she jumped up and stood on the ends of the swing I was sitting on, placing her feet on both sides.
By doing so, my face was positioned exactly between Nayeon’s crotch.
I was flustered and looked up at Nayeon, my face turning bright red.
"Uh...? W-what are you doing..."
Instead of answering, Nayeon gripped the swing chains tightly, pulled her hips back, and kicked her legs out with force to create momentum, starting to move the swing back and forth.
"U-ugh...?"
Nayeon skillfully used her pelvis to create momentum. Especially every time she swung forward, my face was buried and pressed firmly between her thighs.
"U-ugh...?"
The feeling of her warm, soft flesh was transmitted directly to my face.
Nayeon didn't care that my face was touching her there; she focused entirely on kicking her legs out and creating momentum for the swing.
Even though she had only done it a few times, the swing soared to a height similar to what I had achieved after dozens of attempts with all my might.
I buried my face in Nayeon’s dolphin shorts and gripped the swing chains tightly with a terrified expression.
Nayeon looked down at me, laughing brightly with a sweat-drenched face.
Then, just as the swing reached its peak and paused in the air for a moment, Nayeon suddenly let go of the chains she had been holding with both hands.
In that state, she quickly crouched down facing me, chuckled, and whispered in a low voice.
"...Hey, catch me."
"O-oh, okay...!"
I was startled and desperately wrapped my arms tightly around Nayeon.
As the swing descended, I squeezed her with all my might, eyes squeezed shut, terrified that she might fall face-first onto the ground.
Nayeon, held in my arms, blushed slightly and smiled happily.
"Ahahahaha! Heehee...!"
And so, until the swing came to a natural stop, Nayeon and I held each other tightly in our arms—one of us terrified, the other laughing happily.
