The Deepening Training
The next day.
As I watched Eunhye arrive at the warehouse, I was pondering what to do with her today when she whispered to me.
“My period’s over now… but are you still going to check my panties…?”
“Huh?! Really?”
“Yeah… I checked this morning and it was fine. It’s been okay all day.”
“Shouldn’t I verify that myself? Take them off, quickly.”
“Hng…”
At my words, Eunhye eventually stood up and slid her skirt down. The panties revealed beneath were no longer the high-waisted ones from before, but the prettier, lower-coverage white design from last week.
I already knew it was true from that, but I waited until the embarrassed Eunhye fully removed her underwear and held it out to me.
The white panties were thrust right in front of my face. I confirmed the clean center with no pad attached, nodded, and accepted them. I neatly folded them with her removed skirt and had her climb onto the bed.
“Should I take everything off again today?”
“Yes. Today I’m going to touch you all over.”
“Mmm… something feels off. Like this is wrong somehow.”
“Haha. Hurry and undress, Team Leader.”
Before Eunhye could dwell on how strange the situation felt, I grabbed her knit top and pulled it upward. While she removed her top, I quickly stripped off my own bottoms, then climbed on top of her as she lay flat on her back.
I drooled a generous amount of saliva into her cleavage, buried my cock between her breasts, and said,
“Alright. Shall we start with paizuri?”
“If that’s what you wanted, why make me take everything off… hyak!?”
“I wanted to see and touch you like this, of course. Come on now. Put some effort into your paizuri.”
“Eut! Hngh! Ahng! Haaang!”
I reached my right hand behind me and slid my fingers into Eunhye’s pussy. As I leaned my body back slightly to reach and began stirring her insides in that somewhat awkward position, she let out an adorable scream of surprise.
My first finger slipped smoothly into her already moist slit, and soon a second joined it, plunging deep to rub her sweet spot. Her hips bucked violently upward, only to be pressed back down by my weight.
“Come on. Your hands are idle, aren’t they? You need to do your paizuri properly!”
“Kyaaang! Haak! Haa! Haa…”
When I flicked her nipples with my idle left hand, she flinched and quickly used both hands to press her breasts together around my cock. As she slowly squeezed and released them in a proper paizuri, I tormented both her nipples and pussy with my hands.
Maybe because it had been a while since my last visit? Eunhye reached her first orgasm faster than before, squirting her juices.
“Hik! Hiiik! Hwaaaaa…”
“Oh. That was quick. Has your sensitivity improved?”
“Haa… haa… haa…”
“Well done. Very good.”
I shook off the copious fluids coating my hand and gave us a short breather. A bit of drool had trickled from the corner of Eunhye’s mouth, her face slightly dazed from her climax. While she recovered from her first orgasm, I gently massaged her breasts.
After a brief afterglow, Eunhye came back to her senses and spoke in surprise.
“J-Jinsu… I’ll do it for you.”
“Did it feel good?”
“Y-yeah… we’re doing it… one more time, right?”
“Of course. Are you ready?”
“Yes. Please take care of— hyat!? Ahng!”
Before she could finish, I slid my fingers back into her pussy. As they thrust deep and fast, Eunhye twisted her waist, desperately trying to endure the pleasure.
I squeezed her breast with my left hand and said,
“Your hands are slacking again, Team Leader. Hurry up and squeeze those tits together and move them!”
“Hik! Yes, yes! Ahng! Hngh!”
Was her high sensitivity a disadvantage in moments like this? Or was she simply overwhelmed because it had been so long since her pussy had been stimulated?
I was starting to worry I wouldn’t get to cum at this rate, so I grew a little impatient. Though I had been caressing her leisurely, her body—already hypersensitive—seemed to enjoy it even more, and she reached her second climax before I did.
After her second orgasm, I finally received a proper paizuri and unloaded a thick load of semen into her mouth. As punishment for making me wait, I made her savor it longer than usual, but Eunhye seemed to understand her fault; she obediently worked her tongue, savoring the cum before swallowing it all.
Because of that, we ran late again and barely made it out of the warehouse in time. Then came the weekend, and the following week arrived.
A week that began with a morning kiss.
During lunch, just like before her period, I laid Eunhye flat, made her take my cock in her mouth, and fingered her pussy until she climaxed.
Eunhye no longer asked about my well-being. Instead, driven by burning lust, she came to the warehouse seeking me out. By the time she started undressing, her panties were already visibly damp with her juices.
To meet her expectations, thorough foreplay, the right atmosphere, and satisfying simulated sex were crucial. But now, it was time for a change.
While pleasuring Eunhye remained important, I also needed to train her to accept intense acts that would satisfy my own desires.
It was time to establish a clear hierarchy. To make her understand that I came first, and that her role was to please me.
So that one day, the Eunhye who now silently obeyed my preferred positions and climaxed in pleasure would proactively suggest positions she wanted.
Turning her into a woman who actively craved sex with me would mean I had successfully taken her from her husband and made her mine.
That was why being considerate toward her ended today.
The next day.
I immediately laid Eunhye down after she removed her pants and panties and climbed onto the bed, spreading her legs. I positioned her head at the edge of the bed, placed a pillow under her neck to tilt her head far back, and settled myself near her head.
“Spread your legs wider. Good. Tilt your head back more. Open your mouth.”
“Jinsu? What are you going to do?”
“Since your period is over, I want to do what I’ve been wanting for a long time.”
“But you usually…”
“Here it comes. Open wide and swallow my cock.”
I rubbed my glans against her naughty mouth. Eunhye opened her lips and took me in. After enjoying the moist warmth of her mouth and receiving a brief service from her soft tongue, I pushed my cock deep toward her throat—the place I hadn’t used in a while.
Eunhye opened her small mouth as wide as possible to accept my cock. She adjusted the angle of her head to match the deepening intrusion, swallowing me all the way to the back of her throat just as I desired.
My glans slipped past her mouth and into the narrow passage with a distinctly different tightness. The shaft followed smoothly. After briefly savoring the squeeze of her throat, I slowly pulled out, giving her time to breathe before repeating the process.
“Mph! Hngh! Mph! Pah! Hup!”
“Ah. That feels incredible, Team Leader. Spread your legs. I want to lick you too.”
“Hup! Hngh! Ahng! Hup!”
As if she had been waiting for my words, Eunhye raised her knees and spread her legs into an M-shape. I grabbed her knees and pulled them toward me. Then I slid my hands down the insides of her thighs and buried my face below her groin.
I wrapped both arms around her thighs to lock her in place, then reached out and spread her pussy wide open. Lifted slightly upward by me, her glistening slit twitched openly, drenched in thick nectar.
With the preparations complete, I lay over her body and pressed my mouth to her pussy, immediately beginning to suck. My tongue repeatedly dug into her entrance, then shifted to nibble and roll her clitoris.
Eunhye, now receiving a thorough pussy-eating from me, trembled and writhed in pleasure. Every time my cock left her throat, she gasped out moans instead of air, expressing both ecstasy and torment.
“Hngh! Hwaang! Hup! Mph!”
“Ah, Team Leader. When my cock leaves your throat, you need to use your tongue and suck it properly. That’s right. Control your breathing. And don’t try to close your legs!”
Even while devouring her pussy, I scolded her whenever her squirming grew too intense and disrupted the position. At those moments, I slapped the insides of her thighs or her ass and thrust deep into her throat to deny her air even longer.
After tormenting her like that for a while, whether from familiarity or exhaustion, Eunhye grew quiet. I continued moving my hips vigorously while sucking on her pussy.
Gently, so as not to hurt her throat. I carefully watched as my cock entered her and withdrew when her breathing became too labored. At the same time, I licked and sucked every inch of her pussy, then bit and sucked on the skin around her pussy and between her ass cheeks, leaving kiss marks to mark that I had used her, that she belonged to me.
Slow, gentle, continuous foreplay.
That day, in the sixty-nine position, Eunhye quickly reached two orgasms. Afterward, to receive my load, she diligently performed paizuri and fellatio while lying down, drinking every drop of my cum.
Having taken a liking to this position, I continued training Eunhye in the same posture for the time being.
Every day when she entered the room, Eunhye would sigh at the sight of the prepared bed, pillow, and me, then undress. She would lie down, tilt her head back, and assume the perfect position to receive my cock.
Once she spread her legs and lifted her hips familiarly, I would feed her my cock while licking her pussy and fingering her.
Usually twice, sometimes three times, I would bring her to climax. When the exhausted Eunhye could no longer resist, I would leave new kiss marks on her ass and beneath her breasts before unloading heavily into her mouth.
In most cases, Eunhye would wait until she had enjoyed all her own orgasms before milking my cum with paizuri or fellatio. But as time passed, she made progress—skillfully using her throat to make me cum with an intensity that rivaled her own final climax.
In those moments, I couldn’t watch her gurgle and savor the semen since she swallowed it immediately. Instead, I would rub my cock and balls all over her exhausted face, around her nose and mouth, marking my territory. Spanking her ass for swallowing was an added bonus.
By the time her throat pussy had grown wonderfully skilled, I changed the position. I lay down, and she climbed on top of me.
In this new arrangement, Eunhye would skillfully swallow my rock-hard cock with her mouth, performing fellatio. Sometimes she would use paizuri or her throat to make me cum, then calmly catch and drink my erupting semen.
“This position is much more comfortable. The last one felt too… restrictive? It was a bit difficult.”
“I did it on purpose to give you that feeling. Did you dislike it that much?”
“Huh? Mmm. It’s not that I disliked it… it wasn’t bad, but… I wouldn’t choose it if I had the option?”
“Aha! Then I’ll just have to punish you with it occasionally!”
“Punish? You? Me?”
“Hehe. I’m just kidding. Come here, hurry!”
“Kyaaak! Jinsu, you—!”
I continued to satisfy Eunhye steadily in the sixty-nine position. Although repeating the same posture every time could have grown boring, Eunhye was a highly sensitive woman with excellent responsiveness. With so many areas still left to develop, she only grew more sensitive and sensual with each passing day.
After switching so that I lay underneath, I repeatedly spanked her ass to arouse her.
The countless kiss marks densely covering the inside of her ass crack were proof of how thoroughly I had developed and trained her. Since I didn’t bite too hard, most faded quickly, but because I left new ones every day, spreading her cheeks still revealed plenty of lingering marks.
At first, Eunhye had hated the pain and protested whenever I left kiss marks. Now, whenever I bit her to create them, she let out sweet moans, her ass quivering delicately as she leaked juices and pleased me.
Her ass—beautifully shaped and perfectly sized—had always been my primary target. Having received the most attention, caresses, and training, it had developed into an outstanding erogenous zone during this period.
Eunhye’s reactions whenever her ass was spanked were excellent. Through my constant training, her ass had begun to learn. Every time my groin slapped against it, or my palm struck it, she felt intense arousal.
Simply grabbing and squeezing one of her ass cheeks firmly, or gently stroking it before starting to kiss, was enough to excite her. By the time I removed her panties, her pussy would be dripping with nectar—a clear sign of successful training.
As a result, with her sensitivity heightened and her libido surging, Eunhye became more tolerant of subtle sexual harassment. She no longer blocked me or cut it short; instead, she began to secretly enjoy it.
She had changed so much that even when I lightly stimulated her breasts or the area around her areolas as we passed each other at the company, or secretly grabbed and caressed her ass, or stole a sudden kiss, she no longer scolded me. Instead, she would blush and show that she liked it.
With such simple daily sexual harassment keeping her body constantly hot, Eunhye’s entire body gradually turned into an erogenous zone. I then began focusing intensively on training her breasts.
Every time I received paizuri, I tormented her nipples above all else. I gently ran my fingers around her decently sized areolas, continuing her excellent sensitivity development.
Not only in the evenings, but now even during morning kisses, Eunhye would have her breasts grabbed and caressed by me. She had begun to proactively offer her chest to me and enjoyed rubbing it against my body while we kissed.
Eunhye, who now frequently let out moans of pleasure while kissing. When we were alone in my office during the morning, it was incredibly cute how she would cling to my arm during conversation, subtly begging to be touched.
At lunchtime, when I spread the ass of Eunhye—who now found it natural to remove all her clothes—the area was still flushed and mottled with lingering kiss marks.
At first she had hated and felt so embarrassed by it, but now Eunhye loved it when I licked that flushed inner cleft with my tongue.
Every time my tongue passed over the kiss-marked skin, she would shiver with a pleasant sting, her ass trembling. Even before we properly began, she was already soaked with arousal.
I would stroke around her pussy with my hand, lick the tightly closed folds, and poke the center, declaring that I would fuck this place someday too. Then, to leave new kiss marks, I would bite and suck the flesh beside it.
Today as well, I brought Eunhye to two climaxes. Then I held her trembling body in my arms while the afterglow still lingered, gently stroking her back. With her eyes closed, breathing heavily and shivering delicately, she enjoyed the sensation for a long while before opening her eyes. Her hand moved downward to grasp my cock.
When I released my arms, she pulled herself back on her own, buried her face in my groin, and began fellatio. When it became difficult to suck with her mouth, she would press her breasts around me for paizuri, then sigh and use her throat as well.
Eunhye’s technique had become quite skilled. If I didn’t hold back, I would cum almost immediately, so I had to exercise considerable patience until I had made her climax twice.
Once Eunhye began her service, I leisurely stroked her hair, enjoying her mouth, breasts, and throat in turn before unloading heavily into her mouth. Then came Eunhye, cheeks puffed out as she held a mouthful of semen and gurgled it. Realizing that using her tongue diligently to savor it would make me let her swallow sooner, she did exactly that.
“Ah~ let me see.”
“Aaaaaah~”
“Good. You took it all in your mouth again today. Now swallow.”
“Haa… hngh!”
Eunhye worked her mouth diligently again, gurgling the load. When I ordered her to swallow, her puffed cheeks moved as she gulped it down in three or four audible swallows.
“Puha! Haa… haa… chu! Churup!”
After swallowing, she immediately took my cock back into her mouth and used her tongue to clean up every last drop.
Well-trained as she was, she thoroughly cleaned every inch with her tongue. She no longer wrinkled her nose at the smell of my cock. Instead, she wore a slightly dreamy expression, showing she had grown far beyond mere familiarity.
Even when I firmly pressed her head down, burying her nose against my balls, she no longer panicked or struggled to escape. She simply breathed deeply from within my groin and licked me with her tongue—a sign of complete adaptation.
Having given Eunhye a sufficient protein supplement once again today, I spent the remaining time sitting her on my lap, holding her as we chatted softly.
Having grown accustomed to secret, hidden lust relief that no one else knew about, our actions to satisfy each other had also become faster. This gave us more free time, and these relaxed moments gradually grew longer.
Of course, they weren’t very long—just a few short conversations—but this time of sharing intimacy after lewd acts was very important. It wasn’t just about exploring each other’s bodies; emotional connection mattered too. It was so that Eunhye would feel willing to have sex with me.
And during this time, I would touch Eunhye’s body all over, checking how far her sensitivity had developed. From her back down to her ass, up her sides to her breasts. While kissing, my tongue explored her mouth, carefully examining every part of her body. It was a crucial period of inspection.
Hmm. It seemed like it was time to move on to the next stage.
“Today, you lie down, Team Leader.”
“Huh? Okay.”
At first, Eunhye had only permitted me because she felt sorry seeing me exert myself. Now she undressed of her own accord to satisfy her own sexual desires.
The old days when she had been wary of me seemed long forgotten. Today, her face was filled with anticipation for how I would pleasure her.
Having done the sixty-nine position continuously lately, Eunhye looked puzzled when I mentioned changing positions, but it was only for a moment. She quickly climbed onto the bed and lay down as I instructed.
Thinking I was going to use her throat again like before, she placed a pillow behind her neck and tilted her head back. I stopped her and made sure the pillow was positioned properly.
“Huh? Why? Weren’t we doing that?”
“Doing the same position every day gets boring, doesn’t it? Today I want to try something different.”
“Hoo. That sounds ominous. What are you going to make me do now…”
“Haha. It’s nothing special. We did it before. I just thought we could enjoy it again after so long. Here, spread your legs for me.”
I grabbed the legs of the lying Eunhye and spread them into an M-shape, pressing her knees down slightly so her pussy faced upward. I placed my cock on top of it and began slowly rubbing back and forth, starting smata.
“U-uh!? Y-you can’t put it in. You know that, right?”
“Do I only do it once or twice? Today I’ll take it slow.”
“O-okay. I understand.”
I held her legs apart and slowly rubbed my cock against her pussy. My glans parted her labia, and the shaft quickly became slick with the nectar already flowing freely. After rubbing all the way to the base, I slowly pulled back and continued the rubbing motion.
Lightly bumping our groins together like real sex was an added bonus.
Slap! Slap! Slap!
In missionary position, as if we were truly having sex, I simply rubbed my cock against her pussy, slowly heating her up. We hadn’t been violently sucking and licking each other in sixty-nine like before, but rubbing my cock as if I might penetrate her at any moment seemed to excite Eunhye tremendously. Her face flushed bright red in an instant, and she covered it with her hands.
The tension of almost, but not quite, being penetrated. To reward her satisfying reaction, I moved my hips, stimulating her pussy from various angles.
My glans would slip slightly between her labia before springing back out. I rubbed her clitoris with my shaft. I used my glans to stroke up and down, tracing circles, pressing just enough to threaten penetration before pulling away.
I nearly got sucked in by the sudden suction from her pussy but skillfully avoided it, carefully observing her reactions.
“Huu! Hng! Haaang!”
Soft moans leaked out in time with my cock’s movements. Nectar flowed whenever my cock passed over her. The delicate trembling of her lower body told me she was enjoying it immensely.
“Huuuu… haaauaa… hng! Ahng!”
Eunhye let out unusually gentle moans while leaking a flood of juices below. Encouraged by her lustful responses, I moved my hips diligently, scraping her pussy with my cock.
And when her trembling began to intensify, I spread her legs wide once more and leaned forward over her. When I moved her hands away from her face, she wrapped her arms around my neck. I grabbed her breasts, and we naturally began kissing.
Schlick! Schlick schlick! Schlick!
At the same time I squeezed her breasts hard, I felt a hot gush against my groin from below. The small tremors that started there spread throughout her entire body, letting me know that Eunhye had reached her first climax and was shaking.
It really did feel like simulated sex, so her reaction to smata was exceptionally good. I wondered how long she could last.
To let her fully savor today’s first orgasm, I paused the smata for a moment and gently massaged her breasts. I adjusted our kiss so she could breathe more freely. With eyes still trembling more than usual after her climax, she said to me,
“Did it feel good?”
“Haa… I like this. I think… I could get addicted.”
“I’m glad you like it.”
“Yeah…”
“Then I’ll continue.”
“Yes… aaahng~ chuup! Chu! Chururup!”
Eunhye’s sensitivity seemed even better today. She moaned in time with my hip movements. Slowly, as if we were truly having sex, I rubbed my cock against her while kissing her and squeezing her breasts harder again.
Seeing how much she was enjoying it, I could tell her body had been developed far more than before.
The way she felt things was clearly different from the past. Every time I moved, I could sense her entire body experiencing ecstasy.
Tormenting her every day was good, but occasionally sharing love through this kind of simulated sex seemed nice too.
She seemed to like it, and if I occasionally gave her this kind of reward, wouldn’t it naturally lead to real penetration and actual sex? It was a solid plan.
And so, we spent the entire lunch break that day enjoying smata.
To be precise, only Eunhye was enjoying it. I was too busy carefully controlling my hips and movements to cum. Still, it was a very satisfying time.
After that day, smata became one of the positions we frequently enjoyed. I rotated through them appropriately, continuing to develop and train her body.
I checked her sensitivity, observed how she was becoming more skilled and obedient to my words, and gradually increased the proportion of smata.
I often couldn’t cum during smata, which was a bit disappointing, but the goal was to reduce Eunhye’s resistance to having sex with me by steadily enjoying this simulated sex. So I continued with the smata and positions that she liked.
What I discovered during this process was that Eunhye didn’t particularly like the act of smata itself—she liked the missionary position.
She did enjoy smata from behind, but her reactions were weaker than in missionary. To be exact, the direction of pleasure she felt was different.
Unlike the pleasure she got from spanking her increasingly developed ass, the impact of my groin against her, or the intense movements resembling real sex, in missionary she seemed to feel excitement and pleasure from being held, communicating, and the act of loving.
Anyway. As we continued these increasingly intimate skinship every day, perhaps that was why we felt even closer? Eunhye opened her heart to me more, and many stories she had kept deep inside began to pour out.
Family matters, sexless marriage, money, fights—sensitive topics she would normally hesitate to tell others. On days when we took a break from lewd acts, she would lie in bed in my arms and consult me about her worries.
After listening to her stories, giving advice, sharing my opinions, and holding her tight, I felt even closer to Eunhye. I had the sense that I was gradually making her mine, coloring her with my own shade. I came to enjoy these conversation times as well.
