Girlfriend Trains the Slave
Right on time for their appointment, the penthouse doorbell rang. Yoo Sori opened the door. There stood Kang Jihyeon, dressed in a perfect office outfit. She froze for a moment, seeing Yoo Sori's bright, innocent face and the warm atmosphere of the home behind her. On the living room table sat a lovingly prepared dinner by Yoo Sori—steaming mille-feuille nabe hot pot and a few neat side dishes.
Seonwoo naturally seated Yoo Sori next to him and Kang Jihyeon across from them.
"Jihyeon, say hi. This is my girlfriend, Yoo Sori. Sori, this is Kang Jihyeon, the manager helping me with work."
"Hi, unnie Jihyeon! Oppa talks about you a lot. Nice to meet you!"
Yoo Sori beamed and extended her hand. Kang Jihyeon forced a smile and shook it.
"...Nice to meet you."
During the meal, Yoo Sori innocently led the conversation.
"Unnie, isn't work tough? Oppa says you're super capable."
"Oh... no, it's just that Master thinks highly of me."
Kang Jihyeon fidgeted in humiliation at eating in front of her Master'sgirlfriend. Seonwoo observed the subtle shifts in their expressions with Harem Scan, savoring it all.
Heh, what a nice picture. One's my girlfriend, the other's my slave. I love this setup.
After dinner, Seonwoo poured wine and got to the point.
"Jihyeon, I called you here because Sori wants to hang out with you."
Kang Jihyeon's wine glass trembled slightly in her hand.
"Me? Hang out... how?"
"Unnie, shall we make Oppa happy together? I can do it great!"
Yoo Sori's eyes sparkled. Kang Jihyeon paled, realizing the cruel intent behind that innocent face. But she had no right to refuse. Glancing at Seonwoo, she forced the words out.
"...If that's what Master wants..."
"Good. Let's get started then?"
Seonwoo grinned in satisfaction.
"Oh, right—first, let's clarify your relationship. Jihyeon, from now on, call Sori 'Young Miss.'"
Kang Jihyeon felt a twinge of humiliation but stood immediately and bowed 90 degrees to Yoo Sori.
"...Please take care of me, Young Miss."
"Sori, call Jihyeon whatever's comfy. Keep calling her unnie, or puppy, or bug—whatever."
"Eek...! N-no! Just... just unnie is fine! Oppa, do we have to? It's so awkward..."
Yoo Sori shook Seonwoo's arm in distress.
"Alright, let's begin. Sori, give Jihyeon some 'training.' She still doesn't know how to please a man properly."
Yoo Sori, muttering "puppy..." under her breath, giggled and replied.
"Leave it to me! Heehee."
In the master bedroom, Seonwoo leaned against the headboard, sipping wine and watching. Yoo Sori awkwardly laid Kang Jihyeon on the bed at first. But the moment her hands touched Kang Jihyeon's body, Yoo Sori's eyes changed.
"Unnie, you're so tense. I'll take care of everything!"
Smiling innocently, she began undressing Kang Jihyeon. Her touch was relentless, belying her sweet voice. After a few exploratory caresses, she pinpointed Kang Jihyeon's weakness—the clitoris—and tormented it more thoroughly than Seonwoo ever had.
"Hngh...! Y-Young Miss... not there..."
"Shh, it's okay. Feels good, right? Unnie, this is your weak spot, huh?"
"Hiiik...! Y-Young Miss, slower... please...!"
"Aw, it's just starting—how can I go slow already?"
"Kkuuht...! Y-Young Miss, s-stop...! Hiiiiiik...!"
Under Yoo Sori's obsessive clitoral assault, Kang Jihyeon lost her mind. Seonwoo teased.
"Sori, has Jihyeon already cum? Go easy on her—it's her first time."
"Nah, this is how you handle a slave! Hehe. And it's more fun than I thought! Her sensitive spots are different from mine, so finding them is a blast!"
Sori's eyes look... off?
As Yoo Sori's eyes gleamed, a system window appeared before Seonwoo.
Hidden Desires: #Monopoly Lust #Stable Love #Masochistic Pleasure #Sadistic Pleasure
Fuck, her desires evolved again? This is... real talent. She instinctively knows without being taught.
While Seonwoo marveled, Yoo Sori couldn't hold back and was already ravaging Kang Jihyeon between her legs.
What kind of monster did I awaken...?
Seonwoo watched the scene with a serious expression. While Yoo Sori focused on Kang Jihyeon's clitoris, he sneaked up behind the distracted Yoo Sori and thrust in suddenly.
"Kyaah! Ah...! Oppa—! How can you just shove it in like that?!"
"Heh, keep going, Sori. I'll do my thing too."
Seonwoo chuckled. Yoo Sori moaned "Aang!" but her competitive streak kicked in—she didn't stop tormenting Kang Jihyeon's clitoris.
"Sori, her womb's a sensitive spot too? Clench your fist and press hard on her lower belly."
"Really?"
With curious eyes, she fisted her hand and pressed down on Kang Jihyeon's lower belly.
Squish—
Kang Jihyeon's reaction exploded. Delighted, Yoo Sori yanked the clitoris hard. Seonwoo pistoned faster into Yoo Sori in sync, and all three climaxed together.
After savoring the afterglow, Yoo Sori spoke first.
"Nngh... Oppa, now put it in unnie too. She looks like she's dying for your cock."
"Got it."
He plunged straight into Kang Jihyeon's still-trembling pussy.

"Eek...!!"
Kang Jihyeon's body arched like a bow. Yoo Sori pressed down on her lower belly again—squish—leaned in for a kiss, and tangled tongues.
"Unnie, feewing good? Hng... Pwah... How's Oppa's cock hitting your womb?"
"Hmph, mmph...! Y-Young Miss...!"
Kang Jihyeon could only moan incoherently through the kiss. Aroused by the sight, Seonwoo thrust deeper toward the womb Yoo Sori was pressing.
"Sori, twist your pressing hand—like drawing circles."
"Yes, Oppa!"
As Yoo Sori swirled her fist on the lower belly, Kang Jihyeon's body shook violently.
"Jihyeon, you look pathetic. Like a total bitch in heat. Getting your clit tortured by my girlfriend, womb stabbed by my cock. Feels good, huh?"
Overwhelmed by shame and pleasure, Kang Jihyeon wailed in near-scream orgasm. Seonwoo flooded her womb entrance with hot semen.
Ding—
Hidden Desires: #Ambition #Show-Off Lust #Capable Man #Women Relationships
Once everything ended, Kang Jihyeon passed out completely. Seonwoo nodded in satisfaction at the new "Women Relationships" in her desires.
"Sori, you're not done yet?"
"Of course not! Oppa, I've got plenty left in me!"
Yoo Sori replied brightly. Seonwoo's hand slowly rose toward her neck.
The next morning, Kang Jihyeon awoke in an unfamiliar bed. Delicious smells wafted from the kitchen. In the living room, a lavish breakfast spread by Yoo Sori greeted her. Yoo Sori smiled in her apron; Seonwoo lounged on the sofa watching TV. The picture of a perfect newlywed couple. Kang Jihyeon felt like an intruder once more.
She approached them and bowed.
"Master, Young Miss... I showed such an embarrassing side last night..."
"No way, unnie! You were super cute yesterday. Let's play again!"
At Yoo Sori's innocent words, Kang Jihyeon screamed internally.
The Young Miss's 'play' is dangerous...!
Last night, it wasn't just Seonwoo's massive cock that broke her. The image of this pure-faced girl mercilessly ravaging her most sensitive spots burned deeper as terror. That bright smile now looked like a demon's grin.
Then Seonwoo set down his newspaper.
"Oh, right. Jihyeon, know any good tax accountants? I've bought a house and made a ton of money—time to handle taxes."
Kang Jihyeon switched to professional mode instantly.
"Yes, Master. I have a very capable friend among the accountants. And... you'll definitely like her."
"Me?"
Seonwoo raised an eyebrow. Kang Jihyeon smiled meaningfully.
"She's my friend—a true masochist. Not like me, submitting to pleasure, but one who enjoys pain itself."
"Huh? How do you know that? Kinda personal for friends to share."
At Seonwoo's sharp question, Kang Jihyeon hesitated before answering.
"We were high school classmates. She deliberately got bullied. She'd piss off the delinquents on purpose, then get beaten daily. One day, I caught her behind the school—covered in bruises, but smiling like she'd reached ecstasy. When I confronted her, she confessed she loved getting hit, that she was a masochist."
She paused, then dropped a bombshell.
"Later, she told me the delinquents' boyfriends gang-raped her. I was so shocked I reported it to the police. They got forcibly transferred or expelled. But she got genuinely mad at me for snitching—said I stole her fun. Come to think of it... even telling me about the gang-rape, she had this faint smile."
Seonwoo couldn't hide his shock. At the same time, a vicious anticipation for this new prey bloomed in his heart.
