Semen Payment
Chirp, chirp— Chirp, chirp—
The following morning, an alarm I had never set began to ring.
⏰ SEMEN PAYMENT DUE
Today was the mandatory monthly date to surrender my semen to the state. It was a civic duty every man was legally bound to fulfill; despite the exalted status men enjoyed in this society, dodging this obligation brought swift legal retribution that no man could escape.
Before heading out, I took a thorough shower, paying particular attention to my cock and scrubbing it clean until it gleamed.
It's a bit of a trek, I noted, checking the map. The nearest facility, the XX-dong Semen Collection and Payment Center, was about two kilometers from my studio apartment. It was an awkward distance—walkable if I felt like it, but I was feeling lazy. Besides, there was always the risk of pitching an unwanted tent on the sidewalk like yesterday. I decided to catch a cab instead.
"To the semen collection center, please."
"Right away, dear—"
The middle-aged female cabbie smoothly pressed the accelerator. She looked to be somewhere in her mid-forties, with gentle crow's feet around her eyes, hair that had lost some of its youthful volume, and a modest beer belly. It wasn't that she was unattractive; those were simply the natural marks of her age.
How the hell does Auntie Eun-hee stay looking so young, then?
The driver and my landlady couldn't be far apart in years. In fact, Eun-hee might even be the older of the two. Yet when I saw her yesterday, she looked youthful enough to pass for her early thirties, without an ounce of flab around her waist, sporting nothing but massive, perky tits and an extraordinarily round ass.
Screeech—
Lost in yesterday's memories, I arrived at my destination before I knew it.
XX-dong Semen Collection and Payment Center
[Entry Strictly Prohibited to Civilian Women]
Just as I stepped out of the cab, I spotted another man walking through the main entrance of the facility. I followed in his wake, and the moment I entered the lobby, a receptionist greeted me with a radiant, deeply deferential smile.
"Welcome. Are you here for your semen payment?"
"...Yes."
"May I please see your identification?"
The procedure I had researched beforehand was straightforward: confirm identity, undergo a screening for sexually transmitted infections or any underlying health issues that might compromise semen quality, and then deliver one vigorous, refreshing ejaculation. The Sperm Management Corporation employed certified sexual relief technicians on site around the clock, meaning a man simply had to surrender his body to their care and walk out in under thirty minutes.
"Identity confirmed, Mr. Jang Jae-hyeong. Please proceed down the corridor to your left for your examination. Do you have any questions or require any special assistance?"
"I'm fine. Thanks."
I walked down the immaculate hallway, greeted by the sterile, unmistakable scent of a hospital. The men waiting along the benches all shared a distinctly gaunt, hollow-eyed look, as if their souls had been thoroughly drained.
Before long, my name flashed across the large monitor mounted to the wall.
"Mr. Jang Jae-hyeong—please step into Examination Room 2—"
After about ten minutes of waiting, the four men ahead of me cleared out, and a nurse called my name. Stepping inside Examination Room 2 behind her, I found a female doctor waiting in a pristine white coat. She was dressed far more modestly than I had imagined; though her low-cut blouse showed a generous amount of cleavage, by this world's standards that barely qualified as revealing.
"Mr. Jang Jae-hyeong?"
"...Yes."
"Have you experienced any abnormal physical symptoms over the past month? Severe fatigue, acute pain in the genital area...?"
"Not really. I've been taking some time off work, so..."
Living the glorious life of an unemployed bum meant eating whenever I was hungry and sleeping whenever I was tired. Aside from carrying a bit of extra weight, I sometimes wondered if I was actually in disgustingly good health.
"Wonderful. In that case, we will proceed directly with the scan. Nurse Lee."
"Please follow me this way."
I followed the nurse into an adjoining examination suite, where an odd-looking piece of medical machinery stood beside a narrow exam bed.
"We will begin by scanning your flaccid state. Please remove your trousers and underwear over here, then lie face-up on the bed in a neutral posture."
Her tone was strictly clinical, delivered with an emotionless expression that screamed professional training. With those instructions delivered, the nurse turned toward the door and... simply stood there, waiting.
Wait, is she seriously going to stand there and watch me strip?
I hadn't looked into the finer operational details beforehand, which caught me slightly off guard, but the nurse's robotic demeanor left me too intimidated to question it.
"If you feel embarrassed, I can face away."
"Uh... no, it's fine."
As I had learned yesterday, displaying my cock in front of another person was far more embarrassing than I had imagined. But my goal was to become an absolute alpha male. If I intended to bed countless women in the days ahead, I couldn't afford to get flustered over dropping my pants.
Rustle—
Summoning my resolve, I peeled off my trousers and boxer briefs, letting my dick swing freely into view.
"......!"
In that instant, the blank mask Nurse Lee had maintained shattered completely, replaced by an expression of pure, unadulterated shock.
"Mr. Jang Jae-hyeong? Are you... currently erect?"
"No. That's flaccid."
Even a nurse who spent her entire working life looking at male genitalia stared at my crotch in utter disbelief. Then again, considering my flaccid size was already larger than the average man's fully erect cock in this world, her reaction was entirely warranted. She probably assumed, just like Yejin had, that I had undergone surgical enlargement.
Feigning nonchalance, I deposited my clothes into the basket and reclined onto the examination bed. Nurse Lee snapped out of her daze, attempting to rebuild her clinical composure.
"Please... rest your member upward against your abdomen, and part your legs slightly so your testicles are fully exposed."
"Ah... right."
Lifting the heavy, drooping shaft to display the full heft of my scrotum beneath... yeah, this was undeniably humiliating.
Whirrrr—
After a brief moment, the nurse operated the console beside her. The machine hummed to life, gliding into position to begin the scan.
Zzzzt—
A crimson laser swept across the entire length of my member. Watching the high-tech beam glide over my groin felt like something ripped straight out of a science fiction film, eliciting a soft gasp of admiration from my lips. Once the scan concluded, the light shut off, and a fully rendered 3D holographic model of my cock materialized on the nurse's monitor.
"...Gulp."
Examining the internal tissue structure on the screen, Nurse Lee quickly realized this wasn't the result of silicone or implants—it was one hundred percent genuine flesh and blood. Her pupils dilated instantly. I wondered if she realized that the wet sound of her swallowing her own saliva echoed clear across the quiet room.
"Next, we must verify the erect state... Do you require any assistance to achieve an erection?"
Assistance to get hard, huh?
I didn't know what other men requested in this situation, but looking at the nurse right now, I had a pretty damn good idea of what she wanted. Her eyes were trembling, and her thighs were rubbing restlessly together. Despite being an elite nurse trained under the strict standards of the Sperm Management Corporation, she couldn't conceal the fact that she was in absolute heat.
With her desires laid out so transparently before me, there was no reason to hesitate.
"Show me your breasts."
Perhaps because the power dynamic was so glaringly tilted in my favor, the words slipped out without a single stutter. As if she had been waiting for that exact command, she reached up without a heartbeat of hesitation and unbuttoned her uniform.

"......!"
As the pink nurse's uniform parted, an explosive pair of heavy, massive breasts spilled out. Against her pale, flawless skin sat vibrant coral-pink nipples, standing proudly erect. The sight of her stunning, unblemished chest laid bare before me stole the breath straight from my lungs.
"May I... touch them?"
"As much as you like... Please, touch them however you wish."
Any trace of her earlier professional coldness had vanished. Her cheeks were flushed crimson, her breath ragged and shallow. Clasping her hands neatly in front of her stomach, she gazed down at me with eyes practically begging for orders.
"What's your name?"
"Lee Hye-won."
To think I lived in a world where I learned the color of a woman's nipples before her name. A chuckle slipped out at the absurdity of it all, but I certainly wasn't complaining.
Squish—
I reached out and cupped her breast, marveling at the rich, dense weight that spilled over my palm. As I gently kneaded the soft flesh, a breathless whimper escaped her lips. She squirmed on her feet, visibly growing more aroused with every second that passed.
"These are great tits. Think you can get me hard with your mouth?"
"I have never seen one this massive before... but yes, gladly."
Hye-won bent at the waist and pressed her soft, parted lips tenderly against the tip of my shaft. Lying back on a clinical bed while a gorgeous woman served me like this felt like the height of luxury.
Slurp— Chk— Sluuuurp...!
With my hands still buried in Hye-won's heavy breasts, I enjoyed the second blowjob of my life.
"Ngh... damn, that's incredible."
I didn't mean to discredit Yejin, but a certified professional's technique was on an entirely different level. Hye-won exhaled hot, humid breaths over the head to relax the tension, then used her tongue to gently stroke the shaft where sensation was duller, easing me in. It felt less like oral sex and more like a sublime, therapeutic massage.
By the time she began softly teasing the hyper-sensitive glans with the tip of her tongue, keeping myself from snapping into a raging, rock-hard erection was an utter impossibility.
"W-wow... This is truly... I can hardly believe this is a real penis."
Her eyes were completely glazed over as she murmured in genuine worship. Honestly, looking at her flushed face, I wanted nothing more than to blow my load right down her throat.
"Regulations strictly forbid that. Semen collection falls outside my authority..."
Seeing the look in my eyes, Hye-won reluctantly wiped the saliva from my cock, her gaze dripping with bitter regret.
Zzzzzzt—
The erect scan finished in a flash. Leaving the lingering disappointment behind, I pulled my trousers back on, only for Hye-won to quietly press a folded slip of paper into my palm.
"This is my personal phone number. If the opportunity ever arises..."
"I'll think about it."
I slipped the note into my pocket and walked out of the suite.
To be frank, while a one-night stand was fair game, I had no intention of pursuing a serious relationship with Hye-won. As beautiful as she was, her profession required her to attend to countless men, baring her chest and sucking cock on command just as she had for me. It wasn't that I was some narrow-minded unicorn obsessed with virginity, but still... it didn't sit entirely right with me.
Listen to me, getting all high and mighty. Just two days ago, I was a virgin who had never even held a girl's hand.
It was undeniably arrogant, even to my own ears. But at the same time, it proved that I was truly beginning to adapt to this world.
