Chapter 5
I was counting the folds in the tent wall for the ECG and X-ray. Twelve. No, thirteen. If I included the tiniest creases, fourteen. It was utterly meaningless, but if I didn't do something like this, I felt like I'd turn around.
The scene from moments ago still lingered vividly in my mind. The other girls' group—bare breasts under the fluorescent lights. Pink nipples exposed. It was the first real woman's breasts I'd ever seen in my twenty years of life. Nothing like the stuff on internet screens; this was living, breathing flesh with palpable body heat.
Get it together, Han Si-woo. Keep this up and you'll turn into a real pervert.
Behind me, I could hear the other girls' ECG wrapping up—rustling sounds, the researcher's instructions, and still the sobbing. That girl had to get her exam with her chest exposed to a male researcher. She couldn't even cover her sensor-covered breasts as she sniffled. I felt sorry for her, but I couldn't stop that image replaying in my head.
How much time had passed? "Sir over there, we'll do your ECG first."
The researcher's voice called me. I walked with my head down as much as possible, avoiding looking back. Eyes fixed on the floor. Floor, floor, floor. As I moved, I felt three pairs of eyes boring into my back. Especially Na Ye-jin's—it was like a laser.
If you so much as glance back, you're dead. That silent threat crushed my back.
I reached the bed. A narrow one with a white sheet. Next to it sat the ECG machine and monitor. I had to lie down. Flat on my back, staring at the ceiling.
But there was a problem. The same problem that had plagued me all along.
...Please, just go down. Please.
Muttering futile prayers, I gritted my teeth and lay on the bed. And the problem became reality.
Lying on my back, facing the ceiling. Under the fluorescent lights, the front of my black trunk panties—
Was pitching a tent. Standing tall. And the front was stained dark with precum. Glossy and wet, glistening in the light.
...Ah.
The moment I realized it, it was too late. All three girls were staring at my lower half.
Time froze. One second. Two seconds.
"Kyaaah!" Yoon Seo-yeon's scream broke first. Covering her chest with one arm, she slapped her other hand over her eyes and staggered back. Her head whipped around nearly 180 degrees.
"You pervert! What the hell are you thinking?!" Na Ye-jin spat fire. Her yellow hair shook with rage.
Park Ha-young—couldn't say a word. Her mouth half-open, staring at my panties before snapping her head away. Her ears burned bright red.
"N-no, this is! I couldn't help it...!"
"Couldn't help it my ass! What were you thinking to get like that? You virgin pervert!"
Na Ye-jin's words stabbed like daggers into my heart. Virgin. Virgin again. It was true, but why keep rubbing it in?
From my supine position, looking up, I caught glimpses of the three. All had their arms wrapped tightly around their chests. Ha-young crossed hers in an X, covering everything. Yoon Seo-yeon used one arm for her chest, the other over her eyes. Na Ye-jin covered her chest with one arm while pointing at me with the other, grinding her teeth.
"Close your eyes!" Na Ye-jin yelled.
I squeezed mine shut on reflex. In the pitch black, only my heartbeat thundered.
"...We'll start the exam. Stay still."
The researcher began attaching cold sensors to my chest. One, two, three... six in total. My body twitched each time the metal pads touched my skin.
"Breathe normally."
Normally? In this situation? My panties were still tented, and knowing three girls were watching made my heart race like mad.
Beep, beep, beep-beep-beep. The machine sped up. Everyone knew that rhythm was my heartbeat.
"Your heart rate's high. Try to relax."
The researcher said, peering at his tablet. If I could relax, I would. This wasn't a matter of willpower.
"What's it at now?"
I shouldn't have asked. Just curiosity.
"158."
Na Ye-jin's cold voice cut in from behind. "Wasn't it 147 during the fitness test? New record."
Ha-young let out a small sigh. "Si-woo, please calm down..."
Calm down? With three topless girls staring at my erection? That's beyond human limits.
Eyes closed, I recited multiplication tables. 7×8=56, 8×9=72, 9×9=81... Hoping it'd slow my heart even a little.
Beep, beep, beep. The beeps slowed. It was working.
"Good, hold that."
The researcher nodded at the monitor. How long did I lie there? Felt like an hour, but probably under five minutes.
"Exam done."
He peeled off the sensors. Rip, rip, rip. Tiny pains, but nothing compared to the humiliation.
"Get up and move to the X-ray next door."
I cracked my eyes, avoiding the girls as much as possible, and stood. Hunched over to hide my erection, I hurried.
From behind, Ha-young's small voice: "...Ha."
That sigh carried disappointment, resignation, and a hint of pity. Ah, pity in a different sense this time.
I reached the X-ray. A large rectangular plate in front, camera behind.
Glancing back, Na Ye-jin was heading to the ECG bed. Her face burned red—realizing she'd have to bare her chest to the male researcher.
She'd been so cocky earlier, but now her lips were pressed tight. Yoon Seo-yeon gently grabbed her arm.
"Ye-jin, you okay?"
"...Of course. It's nothing."
Na Ye-jin forced a smile, but her trembling voice gave her away.
She lay on the bed. The male researcher started attaching sensors. I turned to face the X-ray.
"Align the plate to chest height."
The plate descended to chest level and stopped. But then—
With the plate lowered, my view cleared. Before, it blocked everything ahead; now, I could see over it perfectly.
To Na Ye-jin getting her ECG. Chest fully exposed.
Na Ye-jin's breasts were voluptuous, true to her D-cup. The volume hidden in black lace now bared under the lights. Dark red nipples stark against pale skin. Large areolas, fitting her size. Lying down, they spread naturally to the sides, but the fullness remained. Sexy, overflowing breasts.

That was the only phrase that came to mind. Nothing like internet pics. Real, living woman's breasts. I couldn't tear my eyes from their subtle rise and fall with each breath.
Na Ye-jin lay with her face turned away, eyes squeezed shut. Ears and neck flushed crimson. The researcher attached sensors around her chest; she bit her lip, enduring.
The same Na Ye-jin who'd been so fierce with the guys earlier. The one who'd called me a "pervert virgin." Now, powerless under a man's touch.
I stared, entranced. The X-ray's position behind the girls meant they hadn't noticed me watching.
How long? "Stop staring and press your chest to the plate."
The researcher's voice boomed. Na Ye-jin's head snapped around. Our eyes met.
Time stopped. Her pupils dilated slowly as realization hit—I'd seen her exposed chest.
Killing intent poured from her eyes. True murderous aura. First time I'd felt anything like it. Spine chilled, hairs stood on end.
The other girls noticed too. Yoon Seo-yeon curled up; Ha-young yelled desperately.
"Close your eyes! Close them!"
I tried, but the researcher said, "Relax your body, inhale. Eyes forward."
"..."
Forward. Where Na Ye-jin was.
No choice—I opened my eyes. Her breasts filled my view again. Nipples seemed even bigger now, erect from cold air and tension. Dark red and firm.
Our eyes met again. Na Ye-jin couldn't speak, lips quivering in rage and shame.
I looked away on reflex.
Click. The shot fired. Please be over.
"Hey, no moving. Gotta retake. Press against it and hold your breath."
Despair at his casual tone. Retake? Stare forward again?
I opened my eyes to check the plate. Now Yoon Seo-yeon was visible—ECG done, she'd shifted but hadn't lain down yet. Clutching her chest with both hands. Tears welled in her eyes, large clear ones sparkling wet under the lights.
But before the tears, my gaze went to her chest. Her small hands couldn't fully cover C-cups; white flesh peeked between fingers. Curves bulging below her palms. Nipples hidden, but the school's top beauty clutching her breasts teary-eyed—
My panties twitched again.
I'm human trash.
Self-loathing surged, but my eyes wouldn't obey.
Click. This one worked.
"Step aside."
I bolted sideways like lightning, plastering myself to the tent wall.
Lesson learned: Face the wall the second exams end. Pavlov's dog now.
Forehead nearly touching the wall, catching my breath—Na Ye-jin's low voice growled behind me.
"...One more glance, and I'll gouge your eyes out."
Too calm—made it scarier. Dead serious. 100%.
"Ye-jin unnie, the exam first..." Ha-young said cautiously.
"...Got it."
Na Ye-jin replied curtly; footsteps receded. Then Yoon Seo-yeon's shaky breaths, bed creak, sensor attachments.
I stared at the wall. Truly, only the wall this time.
But what I'd seen couldn't be unseen. Na Ye-jin's breasts wouldn't fade—voluminous with stark dark red nipples. Plump like fruit, rigid from tension. Even eyes closed, crystal clear.
And Yoon Seo-yeon's teary eyes. Uncovered curves spilling from her grasp.
...I'm going insane.
The tent folds reappeared. Twelve, thirteen, fourteen. Counting couldn't quell this arousal anymore.
