Bladder Lockdown: The Seniors' Naked Scale Ordeal
Everyone had already realized something was off with this inspection. No matter what we said, they could counter it easily, and the researchers could pin any excuse on us. Precision in weight measurements, liability for side effects, time pressure—it was all plausible-sounding reasons. It was obvious they were trying to force us into humiliating each other. But even knowing that, we couldn't escape. We all needed the money.
I stepped up to the urinal. Hesitantly, I adjusted my position, trying to aim the tip of my erect cock at the tiny hole. They said not to spill, so I had to nail it perfectly. The urinal was so small that even a slight angle would send it splashing everywhere. I bore down.
……Nothing.
I pushed harder on my abdomen. I could feel my lower belly tightening, but not a single drop came out. I had no idea peeing while hard could be this difficult. It felt like it was right there, but blocked somewhere. The more I strained, the harder my cock seemed to get.
Behind me, the three girls glanced at each other. Who would be the first to step up naked onto the scale? No one moved. The only sound in the heavy silence was the fluorescent lights humming overhead.
"We're short on time. Please step up."
The female researcher urged them on with a blank expression. Still, no one budged. Of course not. A naked guy was standing right there facing the urinal—any of them stepping forward meant exposing themselves straight to him. Who could just walk into that?
"Hey, you're holding it in on purpose, aren't you?"
Na Ye-jin's sharp voice stabbed into my back. Without turning, I replied,
"N-no…… I really can't……."
"Don't lie. You're holding it just to see us naked!"
"I-I'm serious! I'm trying, but it's not coming out!"
My voice shook. I felt so wronged. It really wasn't coming.
The researcher spoke calmly. "Men usually can't pee easily when erect. The sphincter closes up. It's just physiology—nothing you can do about it."
Na Ye-jin fell silent at the explanation.
"……So we wait until his boner's gone?"
"You can, but it might take a while. Especially in this environment."
Everyone knew what "this environment" meant. A naked girl standing right in front of me. No way my erection was going anywhere.
Silence fell again. Then Na Ye-jin let out a heavy sigh.
"……Fine."
Her face flushed, she took a step toward the scale.
"I'll go first."
She always did this. Na Ye-jin always stepped up first—stripping, enduring inspections, protesting. While Yoon Seo-yeon and Ha-young hesitated, she'd blaze the trail. But not this time.
Yoon Seo-yeon grabbed Na Ye-jin's arm.
"No."
Na Ye-jin turned. "……Seo-yeon?"
"I've always let you go first…… I'm sorry."
Yoon Seo-yeon's voice trembled, but her eyes were clear.
"This time, I'll go first."
"What the hell? You wanna show your naked body to that guy?!"
Na Ye-jin tried to shake off her hand in anger. The "that guy" part stung, but I couldn't argue. I was the naked, boned-up dude standing there.
Yoon Seo-yeon shook her head and gently released Na Ye-jin's hand.
"It's okay."
It clearly wasn't. Tears welled in her eyes, her ears burning red. Yet she walked to the scale and stopped before the researcher. She hesitated. Her shoulders quivered faintly. Then—she reached for her underwear.
Crouching slowly, she slid it down.
I stood at the urinal. I should have looked down. At the urinal. But at the edge of my vision, I saw Yoon Seo-yeon's back. As her underwear slid past her thighs to her knees—her bare ass came into view. White, flawless skin gleaming under the lights. Round, firm curves. Pristine flesh that seemed like it would shatter at a touch. The hidden spot beneath her skirt, one I'd never dreamed of seeing.
My already stubborn pee retreated completely, blocked by my even stiffer cock. Peeing was physically impossible now.
Yoon Seo-yeon flinched. She must have felt my gaze. But she stood slowly, fully removed her underwear, and stepped onto the scale. Completely naked. Not a thread on her. Narrow shoulders, slender waist, the soft curve flowing to her hips. But she couldn't turn around easily.
"Hey! Eyes off!"
Na Ye-jin yelled at me. I quickly looked down at the urinal. But even then, Yoon Seo-yeon's silhouette lingered in my lowered view. The urinal and scale were directly facing each other—her outline stayed in my upper peripheral no matter what.
The researcher said to me, "Don't spill, so aim carefully into the urinal."
It was deliberate. Totally deliberate. "Watch the urinal" meant "don't look away," which was also a free pass for whatever was beyond it. Na Ye-jin got it too—she ground her teeth but couldn't say more.
Seconds passed. Or felt like minutes. Yoon Seo-yeon turned. One hand over her chest, the other her crotch. The sight of her utterly bare nearly made my nose bleed. Voluminous breasts peeking between her fingers. White skin she couldn't fully hide. Long legs, slim waist, flushed face. But it didn't end there.
"Now, attention stance, please."
Na Ye-jin immediately protested. "Why attention for a weigh-in?"
The researcher ignored her. "Attention…… please……."
She just repeated it insistently. Yoon Seo-yeon glanced at Na Ye-jin, then at me. Tear-filled eyes. Crimson face. Trembling lips. But resolute—she dropped her hands.
Both of them. Completely.
Yoon Seo-yeon stood before me in total nudity. For the first time, I saw a woman's complete naked body. And it belonged to Yoon Seo-yeon, the school's top beauty. I couldn't believe it even as I stared.
Large, teardrop-shaped breasts. Gently sloping up top, swelling fuller below in soft curves. On her white, fine-grained skin, they almost glowed under the fluorescents. At the center, dark pink nipples stood erect, maybe from the chill air.
And lower down. A thick bush. Lush pubic hair utterly at odds with her pure face. That gap was insanely hot. Innocent beauty with a dense thicket. The clashing images collided in my head, sending indescribable excitement surging through me.
Yoon Seo-yeon sensed my gaze. A tear rolled from her big eyes. She bit her lip hard, but her chin quivered. She was on the verge of crying.
I was awestruck. I knew it was inhuman. But I couldn't help it. The school's top beauty, fully naked before me. This moment might be worth more than 5 million won.
Na Ye-jin and Ha-young glared in contempt, but I didn't care anymore. The problem was—no pee.
Not even close. Instead, precum dripped steadily. Transparent fluid trailed like a thin thread into the urinal. Definitely not urine.
***
"That's enough. Step down."
At the researcher's words, Yoon Seo-yeon hurried off the scale, covering herself and turning away.
"Line up behind that student."
Behind me. Naked Yoon Seo-yeon stood trembling at a distance behind me. I could feel the space she kept.
And in that moment, it hit me. If I didn't pee—I'd see not just Yoon Seo-yeon, but Na Ye-jin and Ha-young naked too.
No, I shouldn't think that……!
But once it surfaced, I couldn't shake it.
"Hey!"
Na Ye-jin yelled again. "You're holding it to see us naked, aren't you?!"
This time, pure conviction in her voice.
"N-no! I'm trying my best!"
I stammered back. I really was straining my abdomen. But right after seeing Yoon Seo-yeon's body, no way was my erection fading. Even closed eyes brought back those teardrop tits and thick bush vividly.
The researcher said flatly, "Guys usually take a while in cases like this." Then to the scale: "Next, please step up."
Na Ye-jin and Ha-young exchanged looks. Silence. Na Ye-jin gritted her teeth and strode to the scale.
"……I'll do it."
Anger and resignation mixed in her voice. With Yoon Seo-yeon having gone first, it was her turn. She couldn't expect Ha-young to yield.
Standing before the scale, Na Ye-jin glanced forward. Our eyes nearly met, but she quickly looked up. Then—with fiery boldness—she bent at the waist and yanked down her underwear.
Pure Na Ye-jin. She knew dawdling would just make it worse. Quick, all at once.
But that boldness was the issue. Deep bend, ass toward me. As her underwear slid to her knees—in that instant, I saw it.
Her most private spot, exposed raw from behind. Flesh-colored slit between her thighs. And just above, the puckered anus peeking out.
Time froze.
"Ye-jin! That's showing everything!"
Yoon Seo-yeon's scream-like cry burst out. Even covering herself behind me, she'd realized what that angle revealed.
Na Ye-jin finally caught on. Her hand flashed back to cover her ass as she scrambled upright. But I'd already seen it. Her most vital spot.
Na Ye-jin whipped around, face scarlet. Our eyes met. Her gaze held something beyond rage—near murder.
But she said nothing. It was her bold strip that caused it.
She climbed onto the scale, teeth clenched. Staring at the urinal, I wondered: Could I pee now? If anything, my cock felt ready to burst. Precum kept flowing nonstop. The urinal held nothing but precum.
Ha-young next. Would I see her naked too? The thought alone made me subhuman, but thoughts don't obey willpower.
And suddenly—in the corner of my vision. The female researcher was smiling. A split-second thing, maybe hallucinated. But that slight upturn of her lips? Crystal clear.
A wicked smile. Like everything was going exactly to plan.
This inspection was designed this way from the start.
A chill ran down my spine. But below, it burned hotter than ever.
