Eun-kyung's Fox Tricks - Ji-won's Pure Love
The lesson was nearly over.
Kim Mingyu's hands gripped the kickboard tightly, his feet still kicking steadily through the water.
At that moment, Yoo Eun-kyung's hand moved carefully beneath the surface.
Smoothly, yet with perfect precision—
Her fingers slid beneath him, tracing the thick column of his erection through the thin fabric of his swimsuit. She gave it a slow, deliberate squeeze, as if measuring its shape and hardness.
No words were spoken. Just that quiet, lingering pressure before she released him.
The motion felt almost rehearsed in its naturalness.
She touched the wall and spoke as if nothing had happened.
"There... you did great, Min-gyu."
Her cheeks were flushed, eyes fixed on the water.
Kim Mingyu didn't know what to say. His swimsuit was now painfully tight, the swollen head bobbing just above the surface. His body was cold, but everything below was burning hot.
‘...This is way too obvious...’
Yoo Eun-kyung bit her lip, then let out a small breath.
"W-Was that... uncomfortable for you...?"
A tiny laugh escaped her as she tried to hide it behind her fingertips.
"I-I did warn you beforehand, but..."
She hesitated, glancing down before peeking up at his face.
"S-Should I apologize...? N-Nuna...?"
Kim Mingyu felt his mouth go dry. He scratched the back of his head awkwardly.
"N-No, it's fine, sunbae. I was just flailing around. Haha... these things happen, right?"
Yoo Eun-kyung nodded a beat late. Then her expression shifted.
Her eyes were clear, and her lips curved upward slightly.
"B-But still... Min-gyu, your... p-precious place... I made it angry..."
She tilted her head.
"W-Was it because of me...?"
Her voice was soft, but laced with a strange, hopeful note. Her gaze drifted slowly beneath the water, tracing the outline of his erection.
"A-Ah, um... it's really okay! You don't have to worry about it, Nuna, seriously!"
Kim Mingyu waved his hands in denial, cheeks burning as he stared at the ceiling.
Then—
A small, petulant sound slipped from Yoo Eun-kyung's lips.
"...A-Ahn..."
She covered her face with both hands, shoulders trembling.
"N-Nuna..."
She whispered, voice barely audible.
Kim Mingyu tilted his head and leaned closer.
"Huh...? I couldn't hear you..."
Yoo Eun-kyung stared at him for a long moment before speaking even softer.
"C-Call me... Nuna... again...?"
Kim Mingyu blinked, then answered quietly.
"...Eun-kyung Nuna...?"
At that—
"H-Hah..."
The breathy moan was so faint he almost missed it, yet it echoed vividly in his ears.
"It's true..."
Yoo Eun-kyung pressed her lips together, smiling behind her hands.
"Just like A-ran seonsaengnim said... you're way too cute..."
Her eyes sparkled with amusement, but the smile beneath was dangerously satisfied.
"R-Right..."
She slowly lowered her hands and composed herself.
"From now on... call me Nuna..."
After a small laugh, her gaze dropped again.
"A-And..."
Her voice trailed off as her eyes drifted beneath the water, landing directly on the swollen bulge in his swimsuit. There was no shame in that look.
"H-Has it... calmed down yet...?"
Kim Mingyu couldn't meet her eyes. He forced a laugh.
"Hahaha... it's fine, really. The water's cold, so... guys shrink fast in cold water, you know? Haha..."
Even to his own ears, the excuse sounded pathetic.
Yoo Eun-kyung lowered her head, then quietly climbed out of the pool. She returned with two towels and spoke without looking up.
"Y-You can come out now... I-I won't look... N-Nuna promises..."
She held the towel open at waist height, arms spread, head turned away with eyes gently closed.
Kim Mingyu stepped out and approached her. In one smooth motion, she wrapped the towel around his hips, her fingers brushing his skin as her breath grazed his shoulder.
She opened her eyes and smiled at him.
They moved to the sunny deck and sat side by side. Water droplets sparkled in the sunlight.
Yoo Eun-kyung rested her hands on her knees.
"N-Nuna will... teach you a lot more from now on..."
Her words were slow, but filled with quiet certainty.
"A-And..."
She leaned slightly toward him.
"If you ever have worries... c-call me..."
Kim Mingyu rubbed his neck, smiling awkwardly. Her tone was careful, yet her words felt bold and intimate.
"Yeah... I will, Nuna..."
The word "Nuna" came naturally now.
Footsteps approached the deck.
Song Ji-won walked in, stepping into the pool area without hesitation. Her eyes went straight to the two of them sitting together on the deck, towels around their waists, laughing quietly.
They looked far too close.
Her steps faltered. A strange discomfort stirred in her chest—directed solely at Yoo Eun-kyung.
The girl didn't look away. Instead, she pressed closer to Kim Mingyu, their shoulders nearly touching, and met Song Ji-won's gaze with a provocative stare.
Song Ji-won spoke, her expression calm and professional.
"There are no swimming classes today. But it looks like you two had fun playing in the water?"
Her tone was gentle, but cold underneath.
Yoo Eun-kyung smiled faintly.
"A-Ah... what a shame... I-I wanted to teach him more..."
Song Ji-won crossed her arms.
"Well, that's fine. I heard Kim A-ran seonsaengnim is planning some kind of party for the club revival soon..."
Her lips curved, but her eyes were sharp.
"You can do it after that, right?"
"A-Ah... a p-party... S-Sounds good..."
Yoo Eun-kyung nodded and stood up. As she passed Song Ji-won, she turned slightly.
"C-Call me... Min-gyu..."
She paused, then added with a narrow-eyed smile.
"To Nuna..."
The words were the clearest and loudest she had spoken all day—spoken right beside Song Ji-won's ear.
Yoo Eun-kyung walked away toward the hallway.
Song Ji-won watched her retreating figure in silence, her eyes filled with unmistakable emotion.
Once the footsteps faded completely, Song Ji-won finally spoke.
"...You two looked like you were having fun."
Her voice was low and unsteady.
Kim Mingyu flinched and glanced around.
"This is... school, Ji-won..."
The moment he said it—
Song Ji-won's eyes trembled.
"Then...!!"
Her voice cracked with emotion. She stared at him, chest rising and falling.
"I should call you 'seonsaengnim,' right...? Huh?!"
It was the first time she had spoken to him without hiding her feelings, her voice trembling with barely contained anger.
And that anger was directed at him.
She took a deep breath and stepped closer.
"...Do you like her? Eun-kyung? Huh?"
Her lips quivered. She couldn't even explain why she was so upset.
But if she didn't pour it out now, she felt like she would go insane.
‘Kim A-ran... Yoo Eun-kyung... every single one of them... why do they all get in my way...?’
Song Ji-won lowered her head, fists clenched tightly at her sides beneath her skirt. Her arms trembled.
It had been a long time since she had suppressed her emotions this hard.
Biting her lip, a tearful voice escaped.
"I shouldn't say this... because I'm a bad woman..."
Her eyes shimmered with unshed tears.
"I only have Master now..."
Her voice shook.
"I have a husband... I'm committing adultery... with my own student... I'm standing at the edge of a cliff..."
She squeezed her eyes shut, then looked up.
"...Please don't push me off that cliff..."
She sniffled once.
"My heart hurts so much right now..."
She fell silent for a moment, then spoke again, calmer.
"I'm so jealous right now... I hate how indecisive you are..."
She turned to look at him.
"But still... after work, I'll go to Master's house."
She exhaled softly.
"...Because I want to see you."
She pressed her lips together and lifted her head.
"I've said everything I needed to say... I'll be going now."
She turned to leave, shoulders heavy, steps unsteady.
