Intermediate Stage
Intermediate stage.
Vroooom!
“Slurp! Hooom~ Chup! Chururup! Uup! Chururup! Chururup!”
I reached out and grabbed each rotor one by one, turning up the intensity. Every time the vibration grew stronger, Lee Eunhye’s body trembled harder. After cranking up the rotor buried in her anus, I gently tugged the string that had slipped out and pressed it back in with my fingers, teasing her. She twisted and writhed, clearly trying to reject the sensation.
“Hngh! Take it out, take it out~! Please…! Hngh! Hah!”
Lee Eunhye begged for the rotor to be removed the moment my cock slipped from her mouth. I stroked her hair and rubbed my shaft against her lips until she obediently took it back in and resumed the fellatio.
I raised the intensity of each rotor one step at a time, letting her adjust before pushing it higher again. Once every rotor was at maximum, I thrust my cock into her mouth while she could no longer focus on sucking and began tormenting her body with caresses.
“Kuhk! Kuhk! Kuhk! Hah! Hngh! Haaang! Hngh!”
Unable to control her breathing, Lee Eunhye shook her head and spat out my cock. Still, she kept both hands planted on the bed exactly as I had ordered, proving she had grown.
Thinking the training was progressing well, I moved to Lee Eunhye’s left side. Pressing down on her back with my left hand, I lifted her hips slightly with my right and drove my fingers straight into her pussy.
“Hngh! Haaang! Ahngh! J-Jinsu~! Ang!”
Smack!
Lee Eunhye dripped love juices while I fingered her. I slapped her excited ass at intervals, leaving bright red marks.
Her moans, tinged with the sweet ache of pleasure, showed how thoroughly the training had taken hold. As I continued thrusting into her pussy, I spanked her at just the right moments to stoke her arousal even higher.
The moment she was struck, Lee Eunhye let out a cry and raised her hips, clenching tightly. Tears welled in her eyes, yet she still shook her reddening ass and came lightly from the rotors and my fingers.
“Hnnngh! Hah! Haaa…”
After squirting from her climax, Lee Eunhye collapsed onto the bed. Even then she kept her hands glued to the sheets, curling forward on her knees while love juices continued to leak from between her raised hips.
Still in the same position, I gently massaged her ass in circles and asked, “You okay?”
“Hah… hah… It… it feels good… Hngh~!”
“Heh. Our Eunhye has turned into a total pervert. Just how good did it feel?”
My hand that had been rubbing her ass slid down to her crotch. Her thighs were soaked with love juices. When I pushed my fingers inside, Lee Eunhye let out a high-pitched moan and wiggled her hips.
“Haang~! It’s sensitive… Aaaah.”
“You’re completely drenched. How did you hold back when you were enjoying it this much?”
“Aang~ Don’t say such mean things~ Haaa.”
“You’re my woman, so from now on I’ll manage your sexual desire properly. When I tell you to come, you come. When I tell you to strip, you strip. When I tell you to have sex, you do it. Never refuse. Got it?”
“Hngh! Uuung! Ah… I understand. So…! Aang!”
“Good. Then shall we try one more time? Come on, Eunhye, lift your hips~”
“Ang! Ang! Jinsu~! Hngh~!”
At my words, Lee Eunhye raised her body again and assumed the position. Her body, still sensitive from the recent climax, trembled finely in anticipation of the pleasure about to begin. Unable to hide her excitement, she spread her legs slightly for balance.
She lowered her upper body a little and raised her hips in a cat-like pose that made it easy for me to finger her pussy and spank her ass, glancing sideways at me.
I could feel the tension in her back beneath my left hand. Every time I stroked her, her body flinched. Her attention was clearly fixed on my right hand, which was now kneading her tense, clenched ass.
Love juices trickled down between her spread legs.
The three rotors inside her were constantly stimulating her desire, but the way she reacted to the spanking, the way she enjoyed the caresses and massages, and the way she no longer rejected any of it proved the training had been a success. I felt satisfied.
Following Iseul, Lee Eunhye’s body—exactly to my taste—was steadily being developed.
Ever since we began training in the warehouse, I had repeatedly spanked and massaged her ass. Today I confirmed the final result: her body, which used to grow wet just from having her ass stroked, had developed beautifully.
One day her breasts, too, would grow excited from nothing but my touch and scent. She would become unable to live without me.
The beautiful married woman Lee Eunhye was my woman.
After organizing my thoughts, I lifted my hand from her ass. The moment my touch disappeared, Lee Eunhye’s trembling stopped and her back stiffened, showing she was even more tense.
Then my hand came down on her ass.
Smack!
“Ahngh~!”
It was a little harder than the previous spanks that had turned her ass bright red. Lee Eunhye cried out at the sharper pain mixed with pleasure and shook her hips. I kneaded and rubbed her ass to spread the sensation.
Accepting my actions as caresses, Lee Eunhye moaned sweetly and rubbed her ass against my hand, begging for more.
When the reaction I wanted appeared, I thrust my fingers into her pussy and whispered in a suggestive voice, “How is it? This much okay?”
“Hngh… It doesn’t hurt. It doesn’t hurt. Hngh~ It feels good. Do it more~”
Smack!
“Hnnngh! Hah… hah…”
“How about now? Does it feel good?”
“It feels… good…? I’m not sure. Hngh…”
“Really? Then want to take one more?”
Following her response, I brought my palm down a little harder and quickly followed with caresses. As always during spanking training, I stimulated her breasts, ass, and pussy to blur the line between pain and pleasure.
With her judgment clouded by multiple orgasms, I offered her stronger stimulation and raised the level of her ass training another notch.
“Hngh… O-one more…?”
“It felt good, right? Let’s try just one more. Okay?”
While kneading her ass I also rubbed her pussy and clitoris. My left hand reached down to gently massage her breasts. I sucked and licked her ear while speaking in a suggestive voice, preparing to reel her in. Finally Lee Eunhye answered.
“Th-then… just one more time… at the end…?”
“Good. Here it comes.”
Smack!
“Aah~! Hnnngh!”
The crisp sound of flesh echoed through the room. It was the hardest spank I had given her so far. Unable to endure the pain, Lee Eunhye pitched forward again. Holding her bright-red, burning ass high, she trembled. Though she looked pained, the love juices that occasionally spurted from between her cheeks told me she had come from the spanking.
Having confirmed she now orgasmed from having her ass struck, I felt a surge of joy at the new pleasures we could explore. I continued to knead and tease her ass with even more lewd touches.
What kind of play should we try next? How should I develop her body further?
While I was thinking, Lee Eunhye’s pained expression began to change. She turned her head to the side with difficulty. Forgetting the pain, she started accepting pleasure again, her face melting into ecstasy. I kissed her cheek and whispered, “Did it feel good to have your ass spanked?”
“Yes… Hngh… It felt… good… Hngh.”
“Good. Then say it once. Having your ass spanked feels good. Repeat after me.”
I grabbed her ass with one hand, spreading and releasing it repeatedly. Stimulating her with the soft, plump flesh, I made her moan sweetly while she rubbed her ass against my hand and spoke.
“Hah… hah… H-having my ass spanked feels good! Hngh!”
“Well done. From now on, whenever you do something praiseworthy, I’ll spank your ass. Sounds good?”
“Y-yes… I like it. Hah! Please… do it often.”
“Heh. Then you have to ask nicely. Shall we hear our Eunhye beg once?”
At my words, Lee Eunhye lifted her head and looked back at me. Her eyes were hazy, saliva dripped from her lips, and her expression was blank, as if she didn’t understand what she was saying. Slowly she opened her mouth.
“Spank me! Please! Make me feel good… Hah… hah… Spank me as much as you want!”
Her face flushed red as she shook her ass and rubbed it against my hand. Smiling at how perfectly she had completed the task, I stroked her ass and said, “Well done. Here it comes.”
Smack!
“Hngh! Hnnngh! Haa~”
I spanked her ass once more. It wasn’t hard enough to reach a new stage, just strong enough to feel good without burdening her body.
Of course, after spanking her already sensitive ass I immediately massaged it and thrust into her pussy, repeatedly imprinting that this act brought pleasure.
Smack!
“Hngh~ Uuung~!”
Again. I could feel her ass trembling against my palm. I bit and sucked her ear while whispering that it felt good, kneading her ass and touching her erogenous zones to make her feel pleasure rather than pain.
Once her trembling subsided, I stroked her soft ass once more before swinging my hand again.
Smack! Smack! Smack! Smack!
“Aang~ Ang~ Hngh~ Haang~”
Now I struck her more lightly, with weaker force.
I trained her so that her body would unconsciously remember this act as pleasurable rather than painful.
“Hngh!! Jinsu~!”
“Heh. You like it that much?”
“More. Do it more~ Hngh~”
Love juices now streamed down her thighs with every slap. I had been holding back while watching her enjoy being spanked, but I could no longer restrain myself.
“You want more? What a greedy girl.”
“Hah… hah… Jinsu… It feels too good. Hngh! Please do more! Okay?”
“Heh. When you want to be spanked, what did I tell you to say?”
At my words, Lee Eunhye pressed her body against me. Still in the cat-like pose, she shook her ass coquettishly and rubbed it against my right hand while licking my left hand.
“Churup. Hah… Please spank my ass more. Make me feel good, please. Jinsu. Spank my ass. Okay? Please? Hah… hah…”
“Haha. Good. But there’s something even better.”
“Jinsu?”
I made her lie flat on her stomach and stood up. Lee Eunhye looked at me in confusion when I rose, following my movements with her eyes.
I sat behind her and first traced circles on her ass with both hands, gently caressing her. Lee Eunhye let out a soft moan at the touch on her hypersensitive skin. I brought her legs together, adjusted the height, spread her ass, and rubbed my glans against her pussy that was dripping clear fluid.
“You worked hard today, so I’ll give you something even better. Do you know what this is?”
“Hngh! C-cock. Jinsu’s… cock.”
“Correct! You know it well! How did you know?”
I began rubbing my cock against her pussy. The shaft that had carved a path inside her countless times now teased her entrance, sliding back and forth to make her desperate.
Lee Eunhye, perhaps recalling the memory of taking my cock, trembled and panted as she answered.
“B-because I’ve eaten it a lot…”
“Eaten it? You eat cock? Haha. You can say such lewd things now. Eunhye really is a lewd woman~ So where did you eat it? Up top? Or down below?”
“B-both… ways.”
Lee Eunhye buried her face between her arms and answered. The sight was so adorable that I squeezed her ass harder.
I grabbed her large ass again, spreading the plump cheeks as wide as possible, and brought my cock to her exposed pussy. Even with my eyes closed I could find her entrance. I rubbed my glans against it, pushing in and pulling out slightly. Lee Eunhye’s hips twitched in response.
“I see~ How was it? What did it taste like when you ate it? Was it delicious?”
“Hah! Haang! Y-yes! It was delicious! So delicious I’ll remember it forever!”
“Is that so. You pretended it wasn’t, but you actually liked it?”
“Y-yes! That’s right! I like Jinsu so much! Hngh!”
“Good. You said it well. I should give you a reward, shouldn’t I? From now on I’ll spank your ass and feed you cock. So what should you do?”
While stroking her ass and lightly inserting my glans, I spoke. Lee Eunhye seemed to understand what I wanted. She pushed her hips back and took my cock inside herself while speaking.
“Hngh~ Give me your cock~ Fuck me hard! Spank my ass too, smack smack!”
“Good. Well done!”
“Hnnngh~! Haang! Ang!”
Praising her, I thrust my hips forward. My cock reached deep inside her in one stroke, pressing against her organs. Feeling the vibration of the rotor in her anus, I repeatedly buried myself to the root and pulled out, driving her forward.
Along with her ragged breathing, I began proper piston movements while slapping her ass.
Smack!
“From now on we’ll have sex like this. Got it?”
“Y-yesh! Hah! Haang!”
“Lift your ass higher! Keep telling me how it feels!”
“Haang! Ang! Ang! It feels! Hngh! Good! Ang! Aang! Good! So good!!”
We entered full doggy-style sex.

Thinking this would be our last round today, I drove into her relentlessly, releasing all the pent-up desire I had accumulated while tormenting her.
Lee Eunhye’s pussy was gradually becoming perfectly shaped for my cock, just like Iseul’s. The chewy, soft inner walls gripped me tightly. The vibration from her anus and the way her pussy clenched every time I spanked her ass quickly satisfied my lust.
The stimulation from my crotch slapping against her ass also drove her crazy. Even without deliberate spanking, the natural impact made her pussy tighten and loosen repeatedly, and strong moans occasionally burst from her mouth.
Because of that, not long after we started, Lee Eunhye—who had been lightly climaxing from the training—exploded with the pleasure that had been building up.
“Hnnngh! Hngh! Hngh! Haang~”
Lee Eunhye reached orgasm, lowering her upper body and arching her back as she released her pleasure. She wanted to collapse, but because I kept my cock inside her and wouldn’t release her hips, she could only lower her torso while moaning and trembling.
The interval between her orgasms had shortened considerably due to continuous pleasure.
Still, to send her into continuous orgasm today as well, I kept my cock buried in her tightening pussy and gently rubbed and ground inside her, continuing the stimulation.
I planned to keep stimulating her during orgasm and resume pistoning before it ended. So instead of giving her a soothing massage, I thrust deeply, stirring her with circular motions, grinding, and spanking her ass repeatedly.
Just as I was about to start moving again to make her come continuously, Iseul finally finished washing up and came out of the bathroom.
“Oh my. You’re still going?”
“Haang. Haang. Ang. Hngh. Haang.”
“Ah, Iseul. Did you finish washing?”
Iseul emerged from the bathroom wrapped in hot steam. She had washed for a long time, probably because she had been worked hard. After drying her body and hair, she approached the bed.
Iseul went in front of Lee Eunhye, whose body swayed with my hip movements, and lifted her face with both hands.
“Hee. Eunhye unni’s expression is amazing~”
“Haang. Haaang. Ang! Ang! Hngh. Chup! Chururup!”
“Chururup! Chup! Chup!”
Iseul made Lee Eunhye raise her upper body and began kissing her. Lost in orgasm, Lee Eunhye accepted the kiss and instinctively tangled her tongue with Iseul’s, exchanging saliva.
Watching the two women kiss, I resumed moving my hips.
My cock, which had been persistently grinding against her inner weak spots, slowly pulled out and pushed back in, beginning a leisurely pistoning motion.
After holding her still-trembling hips to keep her from escaping or collapsing, I repeatedly thrust and withdrew. My pistoning gradually sped up. Lee Eunhye’s body shook violently, and when kissing became difficult, Iseul pulled her lips away and spoke.
“You’re doing it again? Geez, you beast. Pervert.”
“Hah! Hah! Ang! Ang! Ang!”
“Heh. Haa. Feels good. Eunhye’s pussy tastes so good too.”
Smack! Smack smack!
“Ang! Haang! Ang! Jinsu~ Haang!”
“Tsk. Don’t torment Eunhye unni too much. Take it easy. She’ll hurt her back.”
Iseul said something, but I was lost in the act, shaking my hips in a trance.
I skillfully slapped my crotch against Lee Eunhye’s ass, stimulating her with my hands to make her pussy tighten even more while also arousing her pleasure.
The vibration of the rotor every time I thrust inside stimulated me as well, and I could tell I was close to climax. I pistoned even harder, slapping, spanking, and kneading her ass.
Seeing this, Iseul shook her head and said something else, but it didn’t register. Realizing I was focused, Iseul stood up and headed for the door.
“I’ll go get Byeol. I’ve drawn the bathwater, so please finish up properly, wash up, and rest your body.”
Smack! Smack! Smack!
“Ang! Ang! Haang! Hngh! Ugh! Aang!”
“Hngh. Hngh! Whew. I’m coming, Eunhye! Hah! Haap!”
“Aigoo. That beast. He’s going to overdo it again.”
After one last remark to me, who was lost in sex, Iseul opened the bedroom door and left.
Paying no attention to whether Iseul had left or not, I was completely focused on pounding Lee Eunhye from behind.
I wanted to thrust into her pussy even one more time, to hear her delighted moans, to hear her desperate pleas, to hear her beg for my cock.
And after satisfying my selfish lust one last time, I would fill her pussy with semen, marking her all the way inside.
She might get pregnant, but even if that happened it would only be a little troublesome. On the contrary, it would make her officially my woman, so I didn’t care at all, believing that effort would eventually bring reward.
After all, we were having an affair behind her husband’s back.
Lee Eunhye probably knew it too—that we had already crossed a river of no return.
Sometimes Lee Eunhye seemed to think of me as a man who would pass by briefly. She would think, “So this kind of thing happens in life too,” and while she had somehow ended up in a physical relationship, she would self-deprecatingly laugh, thinking that a married woman like her, older than me, would soon lose my interest.
But that was because Lee Eunhye’s self-evaluation was far too low.
Even if I went out to the busy streets, it was rare to see a woman as pretty as Lee Eunhye. If I sat still all day, would I even see one or two? And not only did she hide such a dynamite body, but she was also kind and good-hearted?
Lee Eunhye’s self-objectification was completely wrong, and that had become an opportunity for me.
After all, our bodies had already mingled. Lee Eunhye had compromised with herself that she would enjoy it until I got bored.
She kept our secret well and filled what her husband couldn’t, so she planned to wait and see for now. She vaguely expected that once my interest faded, the problem would naturally resolve itself.
But that wasn’t the case.
Just as I had fallen for Lee Eunhye, I could feel that Lee Eunhye, who had been trained by me, was also gradually falling for me.
The sexual desire she had forgotten had become active again, and the fact that she was relying on me more and more during the development process—Lee Eunhye knew this but ignored it.
Whenever we had company dinners, she often showed that she missed me when I wasn’t around. Just as I always aimed for the spot next to Lee Eunhye, she naturally took the seat beside me as well.
Every time I saw that, I could confirm that Lee Eunhye’s heart was becoming the same as mine, and I could smile with joy that our love wasn’t one-sided.
Of course, the problem was that she still didn’t fully understand her own feelings, but someday she would recognize my sincerity.
When that time came, would Lee Eunhye be able to push me away? Now that she knew how much she loved sex, could she return to her husband?
I knew that Lee Eunhye and her husband had a good relationship and were harmonious. I didn’t want her to be sad if that relationship broke, but at the same time I hoped she would overcome that pain and come to me as my woman.
So when that time came, to make her think of me even a little, to let go of her emotional burden and choose more comfortably, I would make Lee Eunhye fall for me even more.
Into a body that couldn’t live without me. Into my woman.
Imagining Lee Eunhye someday holding my child and smiling, I moved my hips violently.
I could feel my climax about to explode.
Unable to withstand the continuous doggy-style, Lee Eunhye buried her face in the bed again, raising only her ass to receive my cock. While slapping her ass with my palm, I spoke.
Smack! Smack!
“Haa! Eunhye! Do you like it?”
“Hngh! Ang! I like it! I like it so much! Ang!”
“Kuh! Haa. Good! I’m going to cum in your pussy today too! Don’t you want to feel good like last time?”
“Hngh! Hngh! Ang! Ang! Do it, do it a lot! Hngh!”
Smack!
“Aang~”
“Then beg properly! Fill me with lots of semen?”
I slowed my pistoning a little so Lee Eunhye could speak. With the extra leeway, she straightened her sweat-covered back and pushed her ass toward me, taking my cock all the way to the root while rubbing her flesh against my crotch.
“Hah! Hah! Yes! I’ll beg! Fill me completely with Jinsu’s hot semen!!”
“If you get pregnant, you’ll give birth to my child, right?”
“Yes! I’ll definitely give birth… and raise it prettily! Cum a lot inside! Ang!”
Smack!
“Good! From today on it’s vaginal ejaculation every time! Until you get pregnant! Hup!”
“Ang! Ang! Aang! Hang! Hngh!”
Delighted by her answer, I moved my hips. I didn’t know if Lee Eunhye’s words were sincere or just something she blurted out while drowning in pleasure, but what mattered was that it was an excited and satisfying answer in this moment.
For Lee Eunhye’s sake and for my own, I pistoned my hips diligently. Lee Eunhye, who had been continuously stimulated for continuous orgasm, began to tremble shallowly and quickly reached another climax.
With a successful continuous orgasm, Lee Eunhye’s entire body trembled once more, even harder. Her body paused for a moment before she let out a scream-like moan she couldn’t hold back.
“Hngh! Hnnngh! Hnnngh!”
“Kuh! Go! Go go go!”
I grabbed Lee Eunhye’s trembling hips and mercilessly pierced her tightening pussy that had reached orgasm, repeatedly thrusting in and out.
Lee Eunhye screamed as my cock forced its way in and out of her tightly closed vagina, and she came hard. I leaned forward as if my strength had given out, burying my face between her arms while gripping her hips, pounding to satisfy my lust.
Had I ever had sex with her without consideration like this?
Normally I avoided this situation out of consideration for Lee Eunhye’s feelings, but today I wanted to show overwhelming dominance over her, who had fallen into a perfect trap, while also enjoying the rough, selfish sex I had been holding back.
With the feeling of putting the final touch on all my efforts to conquer Lee Eunhye, I roughly handled her pussy, repeatedly thrusting and withdrawing my cock.
As if masturbating by thrusting into a large onahole, I used Lee Eunhye’s pussy, savoring the tightness, wetness, and softness inside her, before releasing all my remaining strength. Unable to hold back the surging ejaculation, I buried my cock to the root and successfully sprayed my semen inside her today as well, marking that she was my woman.
