The Baby Making Project with Seong Yua
“...”
“Wow...”
Seong Yua stares straight at me without bothering to cover herself. Her body is flawless—smooth, without a single blemish or ounce of excess fat. My cock twitches involuntarily at the sight.
“This is the first time I’ve seen the team leader naked.”
“Yes. The same goes for me.”
“Aren’t you embarrassed?”
“...In what aspect should I feel embarrassed?”
For a brief moment, I sense Seong Yua’s face tightening. Or maybe it’s just my imagination?
“You’re standing here completely exposed—your pussy, your breasts, everything—without a stitch of clothing on.”
“It is a perfectly natural part of sex practice.”
Seong Yua’s expression turns resolute as she continues.
“...I would appreciate it if you stopped testing my work attitude.”
“What?”
What is she even talking about? How did she interpret my words like that?
“I have deeply reflected on the mistake I made previously.”
“Ah.”
The previous mistake. She must be referring to the time I ordered her first blowjob and scolded her when she refused. It seems she had been carrying that incident in her heart all this time.
I waved my hands dismissively.
“No, that wasn’t my intention at all. Testing you? Absolutely not. I know very well how diligently you’ve approached your duties since then, Team Leader.”
“...”
Perhaps the steep rise in Seong Yua’s fellatio proficiency had been her way of making up for that failure.
“......Thank you. I will continue to work hard.”
Her voice and expression revealed not a single trace of emotion, yet...
‘Is she moved...?’
I could feel it, however faintly. The knot in her heart seemed to have loosened slightly, bringing about a subtle shift in her feelings. An unexpectedly vulnerable side of her. Quite the discovery.
‘But of all times, why like this...’
Having this kind of conversation while standing completely naked in front of each other... twitch. It wasn’t my chest reacting—it was my cock.
Seong Yua’s eyes, upon noticing it, sparkled instead.
“Let’s begin right away.”
Her voice carried clear determination. It seemed our earlier exchange had served as powerful motivation.
Seong Yua immediately lay down on the bed, spread her legs, and used her own hands to part her pussy lips.
“...Team Leader?”
“It’s right here. Please insert it.”
What kind of overwhelming girl-crush energy was this?
“Right now?”
“Yes. Is something wrong? Do you need to urinate?”
I had planned to start with foreplay, but Seong Yua’s sexual knowledge was practically nonexistent. To her, “sex” literally meant nothing more than inserting a cock into a pussy and moving it around.
“But at the very least, it should be wet first... Hm?”
My gaze fell on her pussy. Looking closer, I realized she was already soaked.
“I made sure to get it wet on the way here. I found it more efficient to prepare beforehand before beginning intercourse.”
“On the way here? Where exactly?”
“In the car. While waiting at a red light.”
“...”
So “getting it wet” meant she had masturbated. The mental image of Seong Yua gripping the steering wheel while fingering herself under her skirt was incredibly arousing.
“Just a moment.”
However, Seong Yua was still a virgin. Unlike with Gong Jiyun, my Sex Master skill wasn’t at level five. Simply thrusting in wouldn’t create a satisfactory memory.
I pretended to retrieve something from the drawer and pulled an item from the app.
◈ A lubricant containing mild aphrodisiac properties.
◈ Facilitates smooth friction despite its weak effect.
◈ Rapidly absorbed through mucous membranes and disappears, but do not worry. It will soon be replaced by her natural juices.
“What is that?”
“It’s love gel.”
“I’m already wet.”
“You seem familiar with it?”
“Yes. I learned about it while researching intercourse.”
Seong Yua rose from the bed and approached me.
“Hand it over. I will apply it myself.”
She took the tube with surprising eagerness. She really was full of motivation.
Seong Yua braced one hand on the bed, pushed her ass toward me, and then...
“...Huh?”
She inserted the protruding nozzle of the love gel tube directly into her pussy hole and squeezed.
Squuuueeeze—Sluuuuurp—
“Hng...!”
Seong Yua flinched at the cold, slippery sensation. Her ass clenched for a moment. Roughly a third of the 550ml tube had been emptied inside her.
‘It contains aphrodisiac... Is it okay to put that much in?’
Well... the description said the effect was weak, so it should be fine.
Seong Yua grabbed her own ass cheeks with both hands and spread them apart.
Squelch—
Her pussy hole opened along with them, releasing a sticky sound. Then she closed her cheeks again.
Schlurp—
As the hole closed, the gel inside made an obscene noise as it flowed back out. She repeated the motion.
Squelch— Schlurp. Squelch— Schlurp. Squelch— Schlurp.
‘...What the hell am I watching right now?’
The sight was insanely arousing. Blood rushed to my cock.
She continued the process until white foam began forming around her hole.
“It’s ready. Please insert it now.”
Seong Yua spread her ass wide again as she spoke.
“Uh... what exactly did you just do?”
“I spread the love gel evenly inside my vagina.”
“...Where did you learn to do that?”
“The internet.”
I wondered what kind of sites she had been visiting.
“...Well done. It’s incredibly hot.”
“This arouses you?”
“Yes.”
“An unexpected benefit. I don’t quite understand it, but I will make a note of it.”
I grabbed Seong Yua’s hips and rubbed my glans against her entrance.
“Hng, ah...”
A suppressed moan escaped her. When I glanced up from where we were joined, I saw that her ears and the back of her neck were already flushed red. The aphrodisiac must have started taking effect.
‘The description said it absorbs quickly, but damn, that was fast.’
Some of that white foam around her hole might not be gel at all—it could be hers.
Sluuurp—
As my glans pushed inside, foam was forced out through the tight gap. Her thick entrance gripped me warmly. Though narrow, it was incredibly slippery and relaxed enough that entry was smooth.
Schlick—
I pierced her hymen.
Thrust—
“Hah... ngh♡”
My glans pressed against her soft cervix.
“Haa... her pussy...”
That same Seong Yua was now connected to me. I could see her back and nape stiffen.
“Does it hurt?”
“There was a brief moment of pain, but it doesn’t hurt at all now.”
The aphrodisiac had clearly done its job.
“As usual, please provide quick and detailed feedback.”
“Understood.”
I began moving my hips.
Squelch squelch squelch squelch.
“Hah, ngh, hup, hungh, keut...”
Seong Yua clenched her teeth, trying to suppress her moans.
“Haa... Team Leader’s pussy... I’ve only ever felt it with my fingers before, but it’s so incredibly tight and chewy...”
“Hup, ngh, keut... I-is that... feedback?”
“Of course. I’ll describe exactly how your pussy feels, so use that to adjust how tightly you squeeze.”
“U-underst— hng...”
Squelch squelch squelch squelch.
“Thanks to the gel... your pussy is so slick. Team Leader, is this the gel or your own juices?”
“Hng, keut... M-mostly the gel, but... I can feel my juices pooling in the space before my cervix.”
“The space before your cervix... Ah, here it is.”
Squish—
“Hoo, hah♡”
“Oh, when I press here, thick fluid squirts out with a wet sound.”
“Hng, hup... Yes, yes... Those are the juices that had been collecting.”
Squelch squelch squelch squelch.
“Wow... Every time I press firmly against your soft cervix, your pussy squeezes me so tightly. Are you doing that on purpose?”
“N-no. It has nothing to do with my— hup♡ —will... Every time my uterus throbs, my legs clamp together and my hips tense on their own, causing me to— hng♡ —squeeze your cock involuntarily.”
“What if I press even harder on purpose?”
“W-wait... Please don’t— ho, hohk♡”
I thrust deep and ground my glans firmly against her donut-shaped cervix. Seong Yua’s mouth rounded as she let out an indecent sound. Shocked by her own voice, she quickly covered her mouth with both hands.
“K-Kim Junyoung! The uterus is not a toy! Such behavior should be refr— hi, heok♡ Ho, hooohk♡”
“There we go. Cervix grinding. How does it feel?”
While pressing hard against her cervix, I began rotating my hips, rubbing her sensitive spot in circles. The sudden assault must have caught the lecturing Seong Yua off guard; she threw her head back sharply.
“S-stop! This is a serious matter! The uterus is an extremely important organ for making babies— hik♡ Hek♡ Hok...! D-don’t— hoooohk...!”
Grind grind grind...
“Yes, yeees.”
As her cervix was toyed with, her slick pussy clung to my cock, squeezing and milking me rhythmically.
“You need to give feedback, remember? Can you feel how your pussy is sticking to my cock right now?”
Grind grind grind...
“Hng, ho, keut♡ Y-yes... very clearly... hoohk♡ I’m not sure about the sticking part, but Kim Junyoung’s cock— huk♡ Ho, ok! Your c-cock... feels overwhelmingly distinct. The flared rim of your glans, the thickest part of the shaft... Huk, ho-geut♡ K-Kim Junyoung! I am in the middle of briefing! Please stop— ohooooohk♡”
“Whoa, damn... Your pussy just squeezed me so tightly.”
Seong Yua tried to continue her lecture but ended up clamping both hands tightly over her mouth. I kept grinding.
Grind grind grind... Squish, squish, squish, squish...
Thanks to the gel, every rotation of my hips produced obscenely wet sounds. Seong Yua seemed embarrassed by them; she kept shifting the angle of her legs or pressing down on her entrance with her hand, fidgeting constantly.
While her common sense regarding sexual matters had been completely rewritten, she still instinctively felt shame when hearing those lewd noises.
‘That must be why she’s trying so hard to hold back her moans.’
The more I observed her, the more I realized she had quite a cute side.
Squish, squish, squish, squish...
“Hah, keup, ngh, c-cervix grinding, please stop... hoohk♡”
It seemed the combination of the aphrodisiac and my skills made it difficult for her to suppress her moans. She would grit her teeth to silence herself, only for an adorable whimper to slip out, at which point she would quickly cover her mouth again. Then her lips would part once more, repeating the cycle.
The sounds and texture inside her were changing. The sticky fluid filling her pussy was gradually becoming thinner, more like water, and the volume was increasing.
‘Is the gel being absorbed and replaced by her love juices?’
Squish, squish, squish, schluuurp...
The amount was considerable. If not for the changed sounds and texture, I wouldn’t have been able to tell it apart from the gel I had pumped into her. There was that much.
“Huk, hngh♡ Mmph...! Mmph, ho, ok♡ Hogok♡ Ngh♡ Uk...! Mmph, he, heok♡”
Since her moans kept leaking out, she eventually buried her face in the bed. This caused her ass to rise even higher, creating an even more erotic view.
Schluuurp... Schluuup... Schluuurp...
‘Wow... she’s really producing a lot. ...Hm?’
Seong Yua’s body suddenly jerked. Her ass began twitching violently like she was twerking, her legs trembling uncontrollably. Her pussy suddenly clamped down hard on my cock.
“Whoa, shit...! T-Team Leader! Your pussy suddenly—”
Her tight walls convulsed nonstop, squeezing my cock rhythmically.
Squiiiiiirt—!
A powerful jet of fluid sprayed from her pussy with strong pressure.
‘She already came? And so dramatically at that?’
I turned over Seong Yua, who still had her face buried in the bed. Her expression remained completely blank.
No. That’s not right.
Her eyes were moist, the corners of her eyes and the bridge of her nose flushed red. Her chest heaved with heavy breaths, yet she kept her lips tightly pressed together. No—she was biting her lower lip.
‘She’s forcing herself to hide her expression.’
Just like Gong Jiyun. Why were all the women at our company so damn cute when they had sex?
“K-Kim Junyoung. Let’s stop here for today and resume after further preparation next time.”
Her voice trembled, broken up by ragged breaths.
“That sounds good.”
“Yes, then please withdraw slowly...”
“The effect is excellent. A woman begging a man to stop.”
“Pardon?”
“It’s incredibly arousing.”
When Seong Yua felt anxiety, her pussy contracted and squeezed my cock even tighter. I resumed my halted movements.
Squelch squelch squelch squelch squelch.
“Hah, ahng♡ Hup! K-Kim Junyoung! Hah♡ Ho, ok♡”
Her chest and ears were bright red. The aphrodisiac was working properly now.
I interlaced my fingers with hers and pinned her hands beside her head. No longer able to cover her mouth, Seong Yua had no choice but to release her moans openly.
Squelch squelch squelch squelch.
“Huk, hok♡ Ho, ok♡ L-let go— ngh♡ Hah♡ Stop, hah, ahng♡”
Seong Yua shook her head wildly in panic. I knew exactly why. Her pussy was squeezing me tighter and tighter. She was on the verge of climax.
“Huk! S-stop! P-please...! Haaahk...♡”
“Are you about to cum?”
“Y-yes...! Hngh♡ I-I’m about to cum, I’m going to— so please, stop... Kim Junyoung!”
Ah... Seong Yua begging me to stop with her hips. It was insanely hot. If I recorded this and sold it to the guys at the company, plenty of them would give up an entire month’s salary.
A sense of corruption and superiority surged within me.
“Why? You always cum so easily on my fingers.”
“Th-this is different! Only this time! Hngh♡ Hahk♡ No! Please stop, I beg you!”
Squish squish squish squish.
“Stopping now... would be a shame. Your pussy right before climax feels too good. Ah...”
“St-stop! I said stop! Please, no— don’t look at me like this... Huk♡ Keuk?!”
“Oh...! Your pussy is—!”
Seong Yua’s waist arched like a bow, her head snapping backward.
“Hah, hooong♡! Hooooooohk♡! Hot, goooooohk♡”
Squiiiiiiirt—!
Her pussy gushed hot fluid in powerful spurts. Her legs flailed wildly, her heels kicking against my thighs. Her arched back bucked violently, her large D-cup breasts bouncing heavily.
“Hooooooong♡! Hotgeuuuuuuhk♡! Ho, hoooohk♡!”
As she convulsed in orgasm, her movements made it look like she was desperately fucking herself on my cock.
“Hik♡ Hek♡ Hik♡ Hek♡ Hek♡”
“Holy shit...”
That proud, perfect Seong Yua was cumming so obscenely in front of me, impaling herself on my cock. She had completely fallen apart because of me.
She had never been like this before. It was the effect of the Aphrodisiac Love Gel.
‘Where the hell is this “mild” effect they mentioned...?’
Come to think of it, the level one description of my skills also used the word “mild.” Yet they always produced excellent results. It seemed the app’s standard for “effectiveness” was completely different from my own.
“Hng, keuk, hnguuu...”
Seong Yua’s orgasm finally began to subside.
‘Hm?’
She turned her head to the side and covered her face with an arm that had somehow become free.
‘Is she embarrassed about how she looks when she cums?’
The adorable sight made my still-unsatisfied cock throb even harder.
“Ngh♡ Why, why are you still inside...”
I started moving my hips again.
Squelch squelch squelch squelch.
“Hah, ugh♡ Ngh♡ S-stop... hng♡ Stop... please...”
“I haven’t cum yet. Sex only ends when both parties reach orgasm.”
Seong Yua covered her face with one hand and her mouth with the other.
“Mmph, hng, keu, hup♡ Ngh♡ Hah, ngh....”
This time I didn’t bother restraining her hands. The sight of her tear-filled eyes begging me was too pitiful.
After thrusting into her like that several times, Seong Yua’s waist began trembling again. Another climax was approaching.
“Ah... It really is so tight and chewy...”
After one orgasm, her pussy had become incredibly wet and sticky, clinging to my cock. It was a deliciously obscene cunt that didn’t match her usual dignified appearance at all.
“Keu, hup...! K-kiss me! Kim Junyoung! Kiss!”
“What? Why— mmph?!”
Seong Yua suddenly pulled my head down and crushed her lips against mine.
“Mmmngh♡! Mmm♡ Ngh-mmph, mmph, ngh♡!”
Her pussy coiled around my cock, signaling that her climax was imminent. Her legs wrapped tightly around my waist, and the arm holding my head grew stronger.
This woman... ‘Is she kissing me on purpose to hide her orgasm face and moans?’
Since she couldn’t control her body on her own, she was using my mouth to silence herself and clinging to me to suppress her shameful convulsions.
I pushed her shoulders back, breaking the kiss.
“Mwah. Team Leader.”
“Keuk, hup! K-kiss me! Quickly! Kiss me!”
“We are practicing baby making. Correct?”
“Quickly, quickly!”
“The final step of baby making is internal ejaculation.”
“Kiss me— wait? W-what, mmm♡ K-Kim Junyoung...?”
Seong Yua’s face went deathly pale. The strength drained from the arms that had been pulling my head down.
Squelch squelch squelch squelch.
“We should finish the practice properly.”
“K-Kim, Kim Junyoung, wait— hah, ahng♡”
Seong Yua began struggling, pushing against my shoulders.
Squelch squelch squelch squelch.
“S-stop! Kim— hah♡ Ah♡ Kim Junyoung!”
The urge to cum crept up slowly, making my cock twitch. At the same time, Seong Yua’s body froze and her face turned white. Having become an expert on my cock through repeated “briefings,” she could sense my ejaculation timing perfectly.
“N-no...! Inside...!”
She must have felt it already—the impending climax.
Squelch squelch squelch squelch.
