Lewd Idol Trainee Lee Seoyeon's Debut Evaluation: Caught Masturbating in the Bathroom
While Han Seongtae was in the lecture hall, debating who to hypnotize next,
Lee Seoyeon was walking down the hallway with steady footsteps inside the entertainment agency's building, its walls made entirely of glass.
This place, filled with handsome men and beautiful women, was truly a zoo.
No matter how much the agency managed things, it was inevitable for attractive female trainees and good-looking male trainees in their prime to lock eyes with each other—they were only human, after all.
But no one dared touch Seoyeon. She was stunningly beautiful, yet just two days ago, she had despised men.
She had hated even breathing the same air as them in the practice rooms. In fact, because the president of one of Korea's three major famous large entertainment agencies was a man, she had refused to even glance at it despite her mother's desperate pleas.
Pausing mid-step, Seoyeon stared blankly at the photo of the president hanging on the wall.
As evident from the female president's picture, she had chosen this relatively small agency because it was run by women from the top down, with mostly female staff.
Having been a trainee for three years, she had already turned 20 this year. Compared to the ever-decreasing average debut age for idols, Seoyeon absolutely had to make it into a debut group this year at 20.
Why hadn't she debuted yet?
Seoyeon had inherited the genes of her mother, Kim Ayoung, a former actress and model, so her visuals were flawless for a group's center position.
However, she had barely worn makeup, claiming it was just to look good for men.
She dressed in a boyish style and hated skirts—there were hardly any at home to begin with.
Even her D-cup or larger breasts were bound with compression bandages or sports bras to hide their fullness, all to avoid male gazes under the excuse that it was for better dance lines.
Yet her porcelain-white skin like polished jade was more than enough to excite any man.
Was she bad at singing?
Far from it. When her mother Ayoung got pregnant out of wedlock at 20 and retired from entertainment, she had poured endless early education into Seoyeon from birth, hoping she'd achieve the dreams she couldn't.
While other parents sent their kids to hagwon for Korean, English, and math, Ayoung had enrolled her in top vocal training and dance academies, drilling her nonstop. Seoyeon herself had a natural talent and enjoyed singing and dancing, so her skills improved daily.
Singing? Dancing? Visuals? All perfect. So what was the problem?
Her attitude.
When fellow trainees or instructors suggested toning it down just until debut, she shot back that she'd live true to herself.
'But this is me. Why change?'
She simply loved performing dances and songs—she hated the idea of doing it for men. Even though she needed to give her all to make a debut group, her dislike for male evaluators seeped through, preventing her from showing 100% of her potential.
Those unaware of this undervalued her skills.
That's why debut news had been pitch black for her.
Two guys who seemed like male trainees stopped and turned back upon seeing Seoyeon pass by. They said,
"Hey, who was that girl who just went by? Didn't know we had a gem like that in our agency."
"Lee Seoyeon or something? You see her? Fucking gorgeous. She never wears makeup—looks like a whole different person."
"Heard she's a feminist..."
"Nah! That pretty? Bet she has a boyfriend!!!"
Seoyeon stood quietly around the corner of the hallway, out of their sight, listening.
"But didn't her tits used to be that big?"
"Dunno, first time seeing her made up too?"
"She looks kinda sluttier somehow."
"Yo, saw those tits? Insane."
"Fuck tit guy. I'm all about the face. Fucking pretty."
'Definitely...'
Following Han Seongtae's advice, she wasn't binding them anymore, so her ample breasts were visibly straining against her shirt. Seoyeon touched her own chest once.
In the old days, she would've said, "I heard all that, you know? Apologize."
But now, she was thinking differently.
'Yeah... I'm a lewd bitch... But my body and heart all belong to Master... If guys talk like that, Master will surely like me even more. Haa, I wish Master would touch my tits.'
Thanks to the suggestions, all her misogyny was gone, replaced by love for her Master.
'Dancing's tough, but... it's Master's order.'
The two guys were eyeing her, wondering if they should hit on her.
"Yo, ask for her Insta? I'm decent-looking at least."
"Me first."
Pretending not to hear, Seoyeon walked a bit farther away.
Without turning, she sensed them approaching.
One grabbed her shoulder from behind and spoke.
"Hey, hi~ I'm trainee Kim Musik here."
"I'm Lee Yusing."
Musik said,
"Uh... could you give me your Insta? Saw you passing and you're so pretty..."
"Insta? Hmm... I don't really do that stuff..." Seoyeon replied.
"Then how about your number? Honestly, love at first sight."
"Sorry... I have plans after... Master— I mean, I feel like the protagonist. Thanks but no thanks."
"Ah... sorry for bothering you! My bad!"
Seoyeon brushed back her long hair, smiled, and answered.
"Thank you."
She flashed a bright grin.
As the Musick-Yusing duo walked away, their words drifted back.
"Rejected again," said Musik.
"See? Told you she has a boyfriend."
"She smiled at me though."
"That was just awkward politeness."
But they didn't know Seoyeon's true self.
But I'm Han Seongtae's No. 1 human toilet. A toilet can't date other guys, right? Haha.
That the woman before them was a pervert with a condom full of Seongtae's cum in her pocket and a rotor stuffed in her pussy...
'Gotta practice not cumming from the rotor even outside now...'
Suddenly consumed by thoughts of Master, she rushed to the bathroom, sat on the toilet, and started masturbating. A total masturbation pervert.
She turned on the rotor inside her pussy to stimulate her walls and rubbed her clit with her fingers.
'This isn't enough... Master's cock...'
Then, the sound of two women entering.
"Ugh, training was brutal today."
"Me too... Yeoldeok later?"
"Sure."
'Someone came in.'
The two women sat with Seoyeon's stall in between.
Startled, she turned off the rotor.
'But I can't stop my fingers...'
Covering her mouth,
The two women exchanged messages on their phones.
They opened their doors simultaneously, pretending naturally by turning on the faucet for water noise.
Then they approached the stall with the sounds and pressed their ears lightly against it.
Seoyeon noticed from the shadows and shoes under the door that the two were close.
More than that, no footsteps of them leaving after shutting off the water.
'I... should stop...'
'Sounds are leaking...'
'Am I this lewd because of Master...?'
'But it's hard to hold back when I think of Master...'
Pressing their ears to the door, the two women nodded at each other.
Soon, the sound of them leaving.
She turned the rotor back on, opened the condom full of Seongtae's cum, and buried her nose in the long-stretched rubber, inhaling deeply.
"Haa♡ haa♡ Master.. Master..!♡"
'Haa♡ haa♡ I came with my fingers in the bathroom...'
Seoyeon realized she had an exhibitionist streak.
'I definitely get more excited thinking someone's watching...'
'Hehe. Gotta tell Master later and beg for stuff like naked walks...♡'
"Oh right. Gotta report to Master that I came~"
She prepared to take a photo for Master.
First, she filled her mouth with Seongtae's cum from the condom.
She unbuttoned her shirt fully, lifted her bra to expose her nipples. On her belly, where her uterus was, there were two marks drawn by Seongtae.
One from when she offered her virginity in cowgirl, the depth penetrated. The other from deepthroating Master's cock fully.
'Mark that says it's mine~' she recalled Seongtae's words.
The rotor, pushed out by her juices, was slightly protruding from her pussy.
With one hand in a V-sign, she snapped the photo, mouth open to show it full of Master's cum.
With cum in her mouth, she gargled it 'glug glug,' bubbling and savoring.
Then,
"Thanks for the meal. Wanna clean your cock hehe."
She sent a short video along.
Seoyeon wiped her pussy and thighs clean with wet wipes, fixed her clothes, and exited the bathroom casually.
She misted her flushed, excited face and covered it lightly with foundation.
Finished her smudged lipstick from drool and stepped out.
But the thick, fragrant cum scent filling her mouth was intoxicating—she skipped brushing her teeth. Anyone close would smell it...
The two female trainees stood a bit away from the bathroom.
Seoyeon glanced left and right as she emerged, then strode off regally like a queen to her evaluation spot.
"Lee Seoyeon??? That's her, right?"
"Looks like it? First time seeing her made up?"
"She's like that?"
"Seems so? The pure one who freaked at guys..."
"Total plot twist."
"Real shock."
Their conversation didn't reach Seoyeon.
Soon, a mirror-walled room filled with people.
Nearly the final evaluation before debut group selection.
Once confirmed, the agency goes into intensive management: 6 months to over a year of dorm training.
Singing and dancing basics, plus variety skills training. Phones confiscated, outings controlled, home visits like military leave.
Still, making debut group almost guarantees debut—the most crucial chance.
Seoyeon sat waiting, heart pounding.
"Hoo... Nervous... Oh right! The calming pill from Master."
She pulled one from her pocket, ate it, recalling Seongtae's suggestion.
'Eat the calming pill I gave you, and you'll regain calm, gain confidence to do anything. Dance and sing like top idols on TV. Fighting!'
'I'll do my best, Master!'
Soon, her turn.
"Let's start. Trainee No. 74, Lee Seoyeon?"
"Yes! Hello! Trainee No. 74 Lee Seoyeon here. I'll do my best."
"Vocal first."
In the vocal test, thinking of Master, she unleashed her clear, powerful voice freely. The night before at the restaurant, Seongtae had suggested she wouldn't tense up and could show full skill, so she poured it out.
Love-themed songs she once hated now overflowed with appeal, filled with Master's love.
"Great vocals. Emotions really alive."
"Thank you! I worked hard!"
"Now dance. Music, cue!"
For dance, Seongtae's suggestion let her perform every envisioned move naturally, more graceful and sharp than anyone.
Sweat beading, but no sign of strain—Seoyeon smiled happily, captivating evaluators and watchers.
She winked playfully with leisure, like a current top idol. When Seongtae asked her ideal idol, he suggested she could do the same.
During big moves, her large breasts jiggled. Every man there, evaluators included, felt their cocks harden at her lewd, feminine allure—like a bitch in heat.
Glancing sideways, Seoyeon thought, 'No one as good as Master♡', and showed her peak.
That day, singing and dancing, she was the prettiest, most talented queen, enchanting all men.
Her attitude fully changed by meeting Seongtae, she freely showed her talent.
As the seemingly endless test ended, she bowed on stage.
"Thank you. Trainee No. 74 Lee Seoyeon. I'll keep working hard!"
'Did great. First time no regrets. Good feeling! All thanks to Master♡.'
Panting, sweaty, she drank water and awaited judgment.
The judges were already hooked on the new Seoyeon.
"Trainee 74's pretty, huh? Didn't know we had that treasure. Name?"
"Lee Seoyeon. Totally different person these past few days."
"Yeah. First time seeing her that happy on stage."
"Put her in the last spot of the 4-member debut group? Thoughts?"
"Hmm... Yeah. Visuals solid, vocals and dance perfect."
"Agree. Attitude better, movements too."
Later, as a real idol, Seoyeon performing on stage with a rotor in her pussy and Master's cheers—still nearly a year away.
After evaluation, heading home, Seoyeon recalled the morning with Mom.
The human toilet side utterly different from the stage idol...
What exactly is a true human toilet....?
