Training Park Hyeon-ju

Once she finished cleaning my cock, she walked to the bed on my command and got on all fours.

Anticipation?

She had been running on high tension ever since I half-agreed earlier. Her ass swayed. Her thighs were already a mess, glistening under the fluorescent light with juices that caught every reflection. Before long she climbed onto the mattress and settled into a cat pose. Her legs parted just enough for her pussy to come into view.

A small pussy that drew the eye. Too small. Was this really the pussy of a thirty-year-old woman? Staring at my glans, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠I genuinely wondered whether it would fit.

Well, the trait will handle it.

"Lower your waist a bit. You said you do yoga, right?"

"Yes..."

Obedient Hyeon-ju. She folded her waist as far as it would go, thrusting her ass high while her back dipped deep.

"Like this?"

"Yeah. Ass sticking up. Good job."

"Yes."

Ohh. Flexible from the yoga, huh. I should make Hye-yun start yoga too.

Thud, thud. My footsteps. Then the sole of my foot suddenly went sticky and unpleasant—I had stepped in my own semen.

Shit.

I lifted my foot and wiped it on the mattress. The irritation lasted only a moment before my eyes locked onto that pure white hill. Her elastic ass rose high. I opened my palm.

Slap.

Just as it looked—springy. Yoga really was the answer, wasn't it? Come to think of it, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠her thighs looked firm too, probably from swimming.

She takes care of herself. Perfect candidate to be the harem's exercise instructor going forward.

That solid, meaty feel. Ripples spread outward from the point where my palm struck.

Slap.

I hit the other side and the same elastic ass sent waves rolling across her flesh.

"Haahng."

I ran my hand along her slender waist and the line of her hips, then gripped her pelvis with my left hand.

"Beg for it, Hyeon-ju. What do you want me to do to you?"

"Please put Ian's cock into my pussy."

Coquettishness dripped from every word. Her ass swayed and trembled. Her small pussy fluttered, shiny with juices. My cock swelled again until it hurt. Our eyes met when she glanced back. I shouldn't have, but the pure expectation in her gaze made me snort a laugh.

Slap.

"Aaahk!"

This time I struck hard enough to leave her ass red. Juices gushed out between her folds.

Get a grip. Look—this bitch is a masochist. An extreme perverted masochist.

"More. Not just 'Ian-ssi.' Don't you have a better title?"

"...Ma... Master, please put it in."

Master. The word already. And I clearly saw her pussy spurt another rush of fluid the moment she said it.

"Hoh. Good. From now on, whenever I want it, you'll offer your pussy, right?"

"Yes."

The smile on her face told me she still thought this was just play. A real slave and master relationship wouldn't look like that—not like the women in those videos. She should be wound tight, only allowed to enjoy herself when the man made a move.

Well, getting the slave declaration alone is already solid progress. Let's see—orgasm? The sex-partner declaration is basically already done...

Three conditions for the mission. All that remained was to make her climax. Too easy.

I gripped my cock and took careful aim at her tiny pussy. The instant the glans docked against her, I looked again at how much smaller she was than the head.

"Is yours small? Or is my girlfriend just big?"

"Huh? Mine is small. I'm sorry, Master."

It must have been a complex; her voice shrank. She turned her face forward again, then dropped her head. From the way I felt her gaze, she was looking down at her own pussy and my glans.

"Hmm... will this even go in?"

"Yes... it will."

Slap.

"Ahk."

I stroked both of her flushed ass cheeks while I considered it. What made her so certain? Without my trait the size difference alone would make insertion nearly impossible.

I let go of my cock. It slapped against my stomach and twitched. Then I reached out and toyed with her small pussy, stroking the slightly protruding inner lips whose color wasn't the prettiest.

"How can you be so sure?"

"...Please allow me."

"Allow what?"

"I'll bring something out for a moment."

Unexpected. But she looked so full of conviction that I gave permission.

"Fine."

She stood, opened the wardrobe, and pulled the bottom drawer completely free. Her hand reached in and came out holding something long and plastic.

A dildo?

Whoa. She was using that to masturbate?

Nowhere near my current size, but still plenty big—exactly the size I used to be before the change. She climbed back onto the bed, knelt, and offered it up with both hands held out respectfully. I picked up the dildo resting on her palms.

"I'm sorry, Master. There's one thing I need to be forgiven for."

"What?"

She suddenly bowed low and began to tremble. The bitch was enjoying the submission. The way her ass twitched with excitement was impossible to miss.

"While Master was sleeping, I took Master's cock out several times without permission and touched it. That dildo is one I bought a little smaller than Master's cock. I thrust it every day while thinking of Master."

Hyeon-ju had looked at my cock while I slept?

"When did you see my cock?"

"The first time was the Monday after the Chuseok holiday. And about five more times when I found the chance... that's all."

I barely remembered. All Chuseok brought to mind was that little brat using my cock to humiliate me in front of the relatives. Looking back now, this huge cock was a blessing, but at the time the stares had been hard to bear.

Come to think of it, Uncle's cock was tiny, wasn't it?

"Huh. Don't tell me you inserted too?"

"Nooo. I was afraid you'd wake up. Just with my mouth..."

She lifted her head and shook it hard, looking genuinely wronged.

"You dog-bitch. Wanted a secret look at your nephew's cock?"

"Haahng—yes. I'm sorry."

Hyeon-ju got excited by the degradation. She had gotten excited when I spanked her earlier too. She had even volunteered to be a slave without hesitation.

Hye-yun's the same. Why do I only keep running into women with strong masochistic streaks?

I looked at the dildo again. The size somehow resembled my old one.

"But this size is way—much smaller, isn't it?"

"That's... huh? Ah! Because I was scared. Master's is too big. But it should still fit."

She definitely hesitated for a second. I had rewritten her perception of people—why hadn't I changed the dildo size? Wouldn't that have been easier?

Ah!!!

"Hmm... then can you show me how you masturbate? I've never seen a woman do it."

"Yes?... That's..."

She lifted her head to look at me, clearly flustered. I stepped closer, cupped her face, and gently stroked her ear. Hyeon-ju's ears flared forward with almost no lobe; they weren't as fun to touch or as sensitive as Hye-yun's, but caressing them still settled my mind.

"I'll ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠fuck you straight through until Saturday evening."

I was young enough that skipping a night's sleep wouldn't matter. I wasn't planning to let her sleep anyway while I thoroughly trained her, but I set the condition—from early this morning all the way through tomorrow.

"Yes?... Yes."

Hyeon-ju's face lit up. She nodded. She went back to the same place and returned with something like a bottle.

"This is... lubricant."

"Ah... so that exists... yeah, go ahead."

Squirt.

She glanced at me once, sat upright on the bed, spread her legs, coated the dildo with lube, and dabbed some onto her own pussy.

"Haahng. Master, I'll start masturbating now."

"Yeah."

My cock sprang back to full hardness. She looked at it, smiled, then lay back with her legs open. One hand rubbed her clit; the little bud popped out.

"Haahng. Master, please touch my clit."

She wasn't talking to me. While murmuring those words she kept rubbing her clit, then took the dildo in her right hand and parted her folds. The glans of the dildo touched her small white pussy; she pushed it in and out in shallow strokes. Her pussy bloomed wide open.

"Do it the way you always do. The name."

"Haahng? Yes? ...Actually, when I masturbate I imagine Ian-nim, but calling you Master gets me the most excited."

Self-brainwashing? Self-suggestion?

So she had come to recognize me as her master while she was masturbating?

"Don't tell me you were calling me Master while you thrust it?"

"Yes... Master."

She gave a bashful little smile, as if asking, Did I do well? On one hand I finally understood why she had been so obedient, and it felt good; on the other, a sudden frustration rose. If she couldn't overcome the pleasure the dildo gave her, her enslavement would be finished before it started. Now I understood why the mission had given me until midnight on February 9th. It meant: subjugate this slut with your cock.

I snatched the dildo, walked to the vanity, and set it down. Then I turned and gripped my cock.

"Cat pose. I need to punish you with my club again."

"Thank you, Master."

She beamed, dropped back into cat pose, lifted her ass, and shook it. A dog tail plugged into her would look perfect. For a second I pictured driving a dog tail into her anus and fastening a collar around her neck; my cock throbbed hard.

Hmm... going too far? First let's just take her.

I gripped my cock, docked the glans against her pussy again, and seized her pelvis with my left hand. Her skin couldn't match Hye-yun's nineteen-year-old softness, but it was still smooth and springy. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠I swept my palm down the curve of her waist, gathered her hip, and squeezed tight.

"Haahng."

"Like that?"

"Yes."

Sssuuk.

The sensation of the glans sinking in. She had claimed she masturbated with the dildo, and the resistance wasn't that strong. But the moment the head finished entering, I was stunned.

It wasn't that her pussy looked ready to tear from the stretch—though watching it expand to swallow my cock was stimulating enough. The problem was her insides. The folds of her pussy gripped my glans as tightly and densely as a snake, writhing and biting. A well-lubricated canal wrapped around the head and rubbed it with natural, living motion. It felt exactly like Hye-yun sucking my hypersensitive tip right after I came.

And the pressure. It made no sense, yet it felt as if a strong hand were squeezing hard—and the pressure varied from place to place. Her vaginal muscles were extraordinary. Finally the outer lips: thick outer labia clamped around the shaft of my cock and it felt incredible. Too good. One wrong move and I wouldn't last.

With Hye-yun I could usually hold out through three of her orgasms before I came once. Here? Two? One? I had no idea. I tensed every muscle and clenched my anus.

"Haahng."

What the hell is this snake-crawling stimulation and this insane pressure?

And that weak uncle of hers had endured this?

"Hmm. Uncle would last one minute max fucking you, wouldn't he?"

"Ang... yes. That premature-ejaculating bastard. He can't even last a minute. So we only did it a few times during the honeymoon, and these days maybe once a year..."

"Huh. Then the dildo is your real husband."

"...That? Yes."

Slap.

"Lewd bitch. Serving a mere dildo as your husband."

The dirty talk and degradation made her pussy clamp down even harder.

"Ahk..."

Could I really let this pussy go? I had resented her, but that had already been mostly resolved. And this taste. If I just walked away, wouldn't I regret it?

I would regret it.

Sssuuk.

"Haaaang!!"

I pushed my cock deeper. The pressure intensified. The vaginal folds stretched and coiled around me even tighter. A twitch ran through me...

In that instant I made the decision completely. I would make her my slave, and the moment the marriage registration with Hye-yun was finished I would bind Hyeon-ju with a marriage registration of her own. Then I would keep her at my side, making her serve both me and Hye-yun.

I grinned.
