The Baby Making Project
“Guhk!”
I ignored her, and a knife-hand strike flew straight into the back of my neck. Sure, it was a woman’s hand, so how much could it really hurt? That wasn’t the problem.
“Guhk, cough! Hrrk…!”
The sudden impact made me choke on the cigarette smoke.
“Guhk, kuh, ugh! Cough!”
“Wow! Critical hit!”
I turned around with an irritated glare and found a woman standing there with a mischievous little-devil smile on her face.
“Cough! Hack! Hey, you fucking…”
Her short bob, just past her shoulders, swayed gently. The breeze that brushed past her carried a mix of shampoo and baby powder. Despite her petite frame, every curve was in exactly the right place—slim where it should be, full where it counted. And her breasts were seriously huge. It was almost unfair how such massive tits could exist on such a small, slender body.
‘Fully packed E? Or maybe a precarious F?’
She was already short, but the delicate lines of her figure made her look even smaller. To sum it up, she had a slender build with just the right amount of healthy volume in her chest, thighs, and ass. And to top it all off, her face was tiny—like a doll’s. A perfect, palm-sized masterpiece.
‘This has to be a scam.’
I usually preferred sexy, glamorous women over the petite type. But with her, the rules changed.
‘She’s insanely fucking pretty.’
This girl easily cracked my personal top three beauties of all time—even if I included celebrities.
“What are you staring at?”
She was the kind of doll-like beauty you’d want to stuff in your pocket. My ball-buddy—well, maybe not—and childhood friend, Jo Minji.
“Hmm… since you don’t have balls, I guess she can’t be a ball-buddy?”
“You crazy bastard.”
Thwack!
“Oof!”
Another critical hit. This one landed perfectly in my gut.
‘Okay, I probably deserved that…’
It really fucking hurt.
“Ugh… hey… you really…”
“Feeling wronged? Guess I didn’t hit you hard enough.”
We’d known each other for a long time, but there had never been even a hint of romantic tension between us. The only exception was back in middle school when I’d had a one-sided crush on her. Even then, Jo Minji had no idea I’d ever liked her.
She genuinely didn’t see me as a man at all.
People who didn’t know us often asked how it was possible—going through middle school, high school, college, and even working at the same company together without anything happening. They’d wonder if she secretly liked me, or if I was just too dense to notice.
‘Absolutely not. I swear on my life.’
She really didn’t see me that way. But Park Youngmin, who didn’t know the full story, always gave us these strange, suspicious looks.
“Ugh… why are you even here?”
“Just because. I was bored. But I’m leaving again.”
“Why?”
“I got to smack you. And I hate the smell of cigarettes.”
With that, she actually turned and walked away. Her moderately thick thighs and petite ass swayed with each step. For some weird reason, Jo Minji always insisted on wearing dress pants instead of skirts, and I was one hundred percent in favor of that choice.
By absolute standards, her thighs were on the slim side. But considering her overall body proportions, they had just the right amount of fullness. It was because she was naturally so slender. When she wore those tight dress pants that clung to her legs, just looking at her was enough to make my lower body react.
The slight triangular gap that formed between her thighs when she walked or stood at attention was an especially arousing detail. And because her entire frame was so delicate, those sleek, dark navy dress pants that hugged her like a second skin looked absolutely perfect on her.
Whenever I watched Jo Minji, I sometimes felt the urge.
‘Maybe I should start hitting the gym again?’
If I just got a little stronger, I felt like I could lift her up and use her like an onahole.
While I was licking my lips at the sight of her, Park Youngmin asked with a slightly awkward expression.
“...You two really aren’t involved at all?”
“Absolutely not.”
To be precise, my head was packed full of filthy thoughts about her, but she had zero interest in me. Best friend. Ultimate bestie. Male best friend. That was the limit.
“Then what was that just now? That didn’t look sweet or lovey-dovey at all.”
“She’s always glued to you except when you’re smoking. That’s what I meant.”
“Because I’m her only friend.”
“Hmm…”
Park Youngmin tilted his head. At that moment, another woman’s voice came from behind us.
“Mr. Kim Junyoung.”
“Ah, Team Leader.”
At some point, Seong Yua had appeared behind me and Park Youngmin.
“Could I speak with you for a moment? Regarding the ‘sales consultation’ matter.”
“Sales consultation, right? Of course, absolutely.”
Talking about the sales consultation was our secret signal.
“I’ll be waiting in the conference room.”
“Yes. I’ll be right there.”
The “conference room” was code for the equipment room. As soon as Seong Yua left, Park Youngmin asked again.
“...What the hell is that about? What kind of sales thing requires you and Team Leader Seong to meet privately every single day?”
“There’s just something like that.”
“You know there are rumors starting to spread, right?”
“Suddenly? What rumors?”
“That you and Seong Yua are having an office romance.”
“...Whose brain-dead idea was that?”
Seong Yua, of all people, dating someone? Inside the company? That was ridiculous.
“I know, it’s bullshit. But it just shows how often you two are seen together.”
“The kids don’t need to know about it.”
“Yeah, yeah.”
It was an uncomfortable topic to continue. I changed the subject.
“How’s your sister doing these days?”
Family talk. It was a somewhat half-hearted deflection, but that was fine. All I needed to convey to Park Youngmin was “let’s drop this topic.” Since he was quick-witted and perceptive, that was more than enough.
“Well…”
That said, talking about Park Youngmin’s sister wasn’t entirely meaningless small talk.
“She’s… just getting by.”
Park Youngmin’s expression darkened.
“...Is the home atmosphere still bad?”
“Pretty much.”
He shrugged, exaggerating nonchalance. Park Youngmin had an older sister who was one year older than him. She hadn’t gone to college and had been unemployed for seven years now.
‘Or should I say a professional freeloader?’
Anyway.
“She had a huge fight with our parents yesterday too.”
From what I’d heard, she didn’t seem like a bad person. But after being a long-term unemployed adult living off her parents, conversations about getting a job were inevitable. It was an uncomfortable topic for both sides, and voices would naturally rise. Her parents were obviously speaking out of worry. She probably knew that too. But people’s mouths often sided with emotion rather than reason.
“What does your sister want to do?”
“She doesn’t really have anything she wants to do.”
“So she’s planning to keep lounging around?”
“No, it doesn’t seem like that either. She feels burdened by her freeloading lifestyle herself. She’s tried a few things.”
“Tried a few things?”
“Yeah. She wanted to be a writer, so she wrote romance novels for two years and failed. She looked around for part-time jobs for another two years. She even got hired at a company for a short while.”
She really had tried a wide variety of things. It seemed she did have the will to earn money.
“Why did she quit the part-time jobs and the company?”
Part-time work had lots of options and wasn’t too burdensome. If she kept getting fired or quitting, there had to be some kind of issue.
“She hates meeting people.”
“Ah, like social anxiety or something?”
“Yeah. According to the doctors, it’s mild social phobia.”
“Hmm…”
Social phobia. In modern society where everything involves interacting with people, that must be incredibly difficult.
‘Well… it’s not really my problem.’
It was a bit pitiful, but that was it. Seeing Park Youngmin looking depressed made me uncomfortable, but I didn’t really care much about his sister. He was my friend, but she was a stranger. When a friend vented, I just listened and reacted. That was all I could do.
“...Hey! Lend me the customer support USB for a second.”
Apparently sensing the heavy atmosphere himself, Park Youngmin changed the subject first.
“Little shit, dodging the topic.”
I playfully put him in a loose headlock. He was always considerate of the people around him.
“It’s on my desk. I’ll give it to you downstairs.”
“Ugh, oh thank you so much, sir.”
Park Youngmin grinned as he escaped the headlock. After smoking a few more puffs, I headed down to the equipment room.
‘Come to think of it, it’s about time to wrap this up.’
I’d invested quite a bit of time. By this weekend, I should be able to devour Seong Yua.
‘I should call her over to my place.’
I opened the door to the equipment room and stepped inside.
+++
It was Friday.
“Slurp, chuup, shllrrp!”
Once again, obscene sounds echoed through the equipment room. Seong Yua’s cheeks hollowed and puffed out repeatedly. Her lips stretched tightly along the shaft of my cock, sucking it with wet, lewd noises. Occasionally, she’d stiffen the tip of her tongue and dig it into my urethra, and the pleasure was so intense it made my vision blur.
“Haa… fuck, whoa…!”
I was trying so hard to hold back my orgasm that drool was leaking from the corner of my mouth. Yesterday’s blowjob had been better than the day before. And today’s was even better than yesterday’s.
Seong Yua’s mouth-pussy was improving day by day.
“Mmmph, gluck, slurp.”
“Hrrk… hah, hrrk…!”
I really felt like I was about to cum any second. As I let out a pleasure-filled sigh and reached to place my hand on Seong Yua’s head—
Slap!
She smacked my hand away.
“Shllrrp! Gulp… What do you think you’re doing?”
She pulled my cock out of her mouth like she was done sucking on a lollipop and swallowed the mixture of saliva and precum that had pooled in her mouth. Her usual cold eyes glared up at me.
“Y-yes?”
“We are in the middle of work. I fail to understand why you would place your hand on another person’s head.”
Even while scolding me, her hand didn’t stop stroking my cock. Shlick, shlick, shlick, shlick… The wet, sticky friction sounds kept coming from my saliva-drenched shaft.
“While it is true that we are partners in the Baby Making Project, the nature of that intimacy is strictly that of colleagues.”
“Ah… so that’s what you… haa, w-wait, but… could you please stop your hand for a… ngh…!”
“Please refrain from excessive physical contact between opposite sexes.”
My brain, overwhelmed with pleasure, couldn’t keep up with the situation and only let out stupid moans.
‘So she’s upset that I put my hand on her head?’
The same woman who had been enthusiastically sucking my dick just moments ago—and was still vigorously jerking me off?
‘...Should I tell her she has a pubic hair stuck on the corner of her mouth?’
“...Yes. I understand, so please, hurry up and put it back in your mouth…”
For now, I reluctantly agreed. Seong Yua knelt again and took the glans back into her mouth.
“Mmmph, shllrp…”
“Haa… haa…”
...It wasn’t completely unreasonable. Seong Yua perceived having sex with me as work. From her perspective, while she was working in the office, a male employee had suddenly started stroking her head.
‘I guess it makes sense that she’d look stern…’
Hmm… I didn’t know what else to complain about. I decided to just enjoy her mouth-pussy.
“Slurp, gluck, shllrrp…”
When my cock began to twitch like it was about to explode, Seong Yua used both hands to gently massage my balls. Then, with her thumb, she carefully stroked the area where the vas deferens would be, right where the base of my cock met my pelvis.
“Ugh! T-there, hah, ngh…!”
Soon after, under Seong Yua’s guidance, I shot my load straight into her mouth.
Spurt! Splurt, spluuuurt!
“Hngh, haaak…! The semen… it’s being sucked…!”
“Mmm…”
Seong Yua closed her eyes and accepted the cum. But today, the ejaculation lasted much longer than usual.
Gluuuursh! Buuuuursh! Spurt! Spurt!
“Uup…?”
“Haaak, haaak…!”
In the end, I kept cumming until both of Seong Yua’s cheeks were puffed out like a chipmunk’s.
“...”
It was an unexpectedly large amount, but the expression on Seong Yua’s face as she held it in her mouth remained perfectly calm.
“Brruu…”
She spat some of it into her palm in advance. Her mouth was so full that it was hard to swirl and savor it properly.
“Mmm…”
She rolled it around in her mouth a few times before swallowing.
“Gulp, gulp, gulp, gulp…”
She did the same with the portion in her palm, carefully tasting it before swallowing the rest.
Seong Yua thought for a moment.
“It’s clear that…”
She opened her mouth.
“Haa… Yes?”
Unlike usual, she used her thumb to slowly stroke the underside of my still rock-hard cock, right along the urethra. The remaining semen inside spurted out.
“Shlop!”
Seong Yua quickly sucked it up, kissing the tip of my glans like she was giving it a peck.
“Tch, shllrp… Gulp. As Mr. Kim Junyoung said, emptying the seminal vesicles daily has clearly increased sperm production capacity.”
“Ah… is that so?”
“Yes. In terms of taste, color, texture, swallowability, and aroma—by every metric, the concentration of the semen has become remarkably thick.”
Seong Yua stroked my cock with her hand.
“The force of ejaculation afterward is also excellent.”
Just as Seong Yua said, the change was clearly noticeable.
‘It’s the effect of the Stamina Booster skill.’
The power of the app really was incredible. I patted Seong Yua on the shoulder as she naturally began cleaning my cock with her mouth. I didn’t touch her head since that would probably make her angry.
“Haa… Let’s move on to caress training now.”
“Understood.”
Seong Yua stood up.
‘Now it’s my turn.’
There was nowhere proper to sit in the equipment room. So Seong Yua simply leaned her upper body forward and braced herself by placing her hands on a box behind her. I slipped my hand under her formal skirt. The hem of the skirt pressed tightly against my wrist. The back of the skirt wouldn’t slide up easily because it was caught on her ass. The skirt itself was tight, and Seong Yua’s butt was quite plump.
‘It’s a little inconvenient, but that’s part of the fun of watching.’
Between the lifted hem of her skirt and her black stockings, a tantalizing strip of bare skin peeked out. She used to wear pantyhose, but she had switched to thigh-high stay-up stockings for our training sessions.
‘Maybe I should make her wear a garter belt?’
Since the skirt was so tight, a garter belt would be visible from the outside. That would definitely stimulate the imaginations of the male employees. I shook off the stray thoughts and focused on the sensation of my fingers.
Soft pussy flesh and slightly coarse pubic hair brushed against my fingertips. I checked Seong Yua’s face.
‘No change in expression even when I’m touching her pussy.’
If it were an ordinary woman, people might have called her a block of wood. But for a beauty like Seong Yua, the metaphor of a doll was far more fitting.
I slid a finger into her tight hole.
Shlup.
Wet, humid warmth welcomed me.
“Please brief me on our work performance to date.”
“Through daily oral sex, we have been performing ejacula—”
“Again.”
“...My apologies. Every day, I have used my mouth-pussy to suck Mr. Kim Junyoung’s penis, extracting semen and emptying the seminal vesicles. Through this, we have encouraged an increase in sperm production capacity, which has recently begun to show modest results.”
“Continue.”
“Additionally, through caress training, I am honing techniques to satisfy women.”
“What technique am I currently practicing?”
“It is fingering. The technique of stimulating a woman’s pussy with fingers to bring her to orgasm.”
“Correct. Therefore, for the sake of feedback, I would like you to brief me on the sensation of the pussy as immediately and as detailed as possible.”
“Yes, understood.”
I stimulated the vaginal walls with my middle and ring fingers while rubbing her clitoris with my thumb.
“How does it feel?”
“The pressure on my clitoris feels extremely pleasurable. However, the vaginal walls require stronger scraping… Ah, aah… That feels good.”
