Your Girlfriend's Bitch Training Complete
I returned to Seoul after wrapping up my business trip to Gangwon-do.
"Hyung."
"Got it. Come to the CEO's office."
"Yes!"
"Send Se-jeong to the secretary meeting."
"You're calling her Se-jeong so affectionately now."
"Why? Don't like it?"
"No. I like it too much."
"You're a really weird guy. She's your girlfriend."
"Hahaha. That's right."
"A guy who likes having his girlfriend stolen is my secretary. I don't know whether to be happy about it or not."
When I entered the CEO's office, Ki-woo came in carrying tea he'd prepared himself. He locked the door and we sat side by side on the sofa.
"Hurry. Tell me everything, hyung."
"Don't jerk off in here."
"Should I move to the bathroom?"
"Are you insane?"
A laugh slipped out. He really enjoyed this that much?
"So, what happened?"
"Nothing special. After the meeting, we had wine and dinner at a restaurant."
Since she was already my bitch, she had no choice but to lie. Still, the feeling was about the same.
"She said she'd been lonely lately. That it was hard after losing So-yoon. So she asked me to hold her. She said let's keep it our little secret, just the two of us tonight."
"……And then?"
"At first she obviously said no because of you. That she felt sorry toward you. That she couldn't do that."
His expression relaxed a little at those words, and the corner of my mouth curled up.
"You like that too, huh."
"Haha. Still, I'm glad she resisted at least a little."
"What good does that do? In the end she spread her legs for me anyway."
"So she eventually gave in to that?"
"After dinner I called her to my room and ordered another glass of wine through room service. Then I pounced on her. When I kissed her and laid her down, she went to the bathroom saying she had to wash up, like she had no choice."
"Kuh! Just imagining it is getting me hard."
"You really like getting stolen from that much?"
"I already knew Se-jeong was interested in you, hyung. Well, not just Se-jeong. How many female employees aren't interested in you? Honestly."
"What's that got to do with anything."
"That's why I understand it. And I'm fine with it because it's you, hyung."
"What are you going to do if Se-jeong's feelings for you really disappear one day?"
"Nothing I can do. I'll just have to give up."
"When are you going to tell her?"
"How was Se-jeong while she was cheating on you without you knowing?"
"She enjoyed it just like in the photos you sent."
"She sounded pretty excited during the call too."
"She seems to secretly like doing it with me behind your back."
"Kuhk. That actually hurts a little to hear."
Ki-woo clutched his chest dramatically.
"Then I guess I'll have to keep pretending not to know a little longer. So Se-jeong can enjoy it more."
"You just want to enjoy it more yourself."
"A bit of both. Hahaha."
"Speaking of which, I'm keeping Se-jeong at my place from today until the weekend."
"……What?"
"She tasted better than I expected. I got pretty worked up too. So I'm going to fuck her all weekend and turn her into my personal bitch."
"Wow…… your bitch. My girlfriend becoming your bitch instead……"
His eyes actually brightened at those words.
"Good. Do it, hyung."
"Thanks. Thanks to you I'm feasting."
"Just send me photos……"
"No photos."
"What?"
"I'll finish her bitch training by Saturday. Come on Sunday and see for yourself."
"……!!!"
"Come see in person how your girlfriend has changed."
She was already my bitch, but if she started acting like one right away Ki-woo would find it suspicious. I had to keep that a secret, so I bought myself some time.
'Even if I told him, he'd forgive me in the end anyway.'
Ki-woo shouted.
"Thank you! Hyung! I'll definitely come on Sunday!"
"Don't tell Se-jeong. I'll show her to you secretly."
"Phew. Yes! I'll do that!"
"And there's one thing I need you to promise."
"What is it?"
"In exchange for me granting your request, you agreed to accept the humiliation, right?"
"Y-yes, that's right."
"From now on, no physical contact with Se-jeong at all. Don't touch her."
"Ah…… You mean not even holding hands?"
"No. Holding hands or hugging is fine. But absolutely no sexual contact. Understood?"
"Se-jeong doesn't do anything with me anyway."
"Don't ask her to help you out with her hand when you get horny either."
"Ah…… Ugh. I'm completely under your control now."
"You were prepared for at least this much, weren't you?"
Ki-woo gave a bitter smile.
"Yes. I understand. I'll try."
"Good. Then I'll show you some fun stuff from now on. Want a little preview today? Let's go."
****
After finishing morning work, I went out for lunch for a change. Riding in the car Ki-woo was driving, I sat in the back seat with Lee Se-jeong.
Squeeze. Squeeze.
"Ugh……"
I openly kneaded her thighs. Deliberately slipping my hand under her skirt, I touched her while Ki-woo watched through the rearview mirror.
"Hah, stop it."
Se-jeong tried to push my hand away, but I moved it even further toward her ass and groped her roughly.
"Seriously, why are you doing this? He'll notice."
I ignored her whispered protests. Ki-woo kept stealing glances through the mirror too.
"It's fun."
"Ah, come on. Hng?"
I deliberately grabbed her breast and let go.
"……It's dangerous. Really."
"Ki-woo, there's a convenience store up ahead, right?"
"Yes."
"Get out and buy three drinks."
"Understood."
After deliberately sending Ki-woo out, I pulled Se-jeong up.
"W-what are you trying to do?"
"You look especially pretty today. I'm getting turned on."
Ki-woo's reaction made it even hotter.
"N-no way?"
I yanked her panties down, pulled out my cock, and thrust straight in.
Thrust—
"Haaah!?"
"Hoo. You're tight. We don't have time, so I'll make it quick."
"T-the smell of cum will be obvious. Hah, stop. Pull out."
"I'm too horny to hold back."
If Ki-woo had any sense, he'd take his time coming back. Thrust— Squish! Squish!


"Your pussy tastes especially good today too. Hoo. I'm so fucking turned on."
"Haaah! Hng! W-we can't. Hah! K-Ki-woo oppa will be back soon. Hah!"
"Wouldn't it be better to make you cum fast?"
"Hng! Hngh! P-President. Hah! Q-quick. Cum inside my pussy right now. Hah! I'm going crazy from the anxiety."
Thrust— Thrust— The wet, lewd sounds grew louder. The dashcam would catch all of this. Even if it didn't, he'd probably left a phone recording somewhere like I told him to.
Squelch. Squish! Thrust! Thrust! Thrust!
"Hah! Haa! Haang! T-too rough! Hng! W-when are you cumming. Hurry! Hah! Oppa is coming."
"I'm cumming."
"I-in my mouth!"
"Good. Swallow it all."
Gluck—! She quickly turned and took my cock in her mouth, swallowing every drop.
Gulp. Gulp. Gulp.
She looked insanely hot. She wiped the cum dripping from her lips with the back of her hand, sat primly beside me, and deliberately opened the door.
"Where are you going, Se-jeong?"
"I-I just need to go to the bathroom for a second."
Her desperate attempt not to get caught turned me on even more. When Ki-woo came back, he laughed at the smell of cum.
"I deliberately stayed out for about five minutes. Looks like it worked out."
"You recorded it, right?"
"Yes."
"Listen to it later."
Soon after, Se-jeong returned and we started moving again.
Pinch—
She deliberately pinched my side and glared at me with a sulky expression. She looked really pretty. This wasn't the end.
On the way back after lunch, I stopped the car at a nearby café and gave Ki-woo an order.
"I'll go."
"Se-jeong and I have something to talk about, so stay here."
"I'll be right back."
While the quick-witted Ki-woo went to buy coffee, I turned Se-jeong toward me and thrust into her while holding her.
"Haaah! This is really dangerous!"
"Then why are you so pretty?"
"Hngh!!"
She wrapped both arms around my neck and moved her hips even more eagerly. She moved extremely provocatively, both for her own pleasure and to make me finish faster.

"You're going to swallow it again this time?"
"Y-yes. At least this way the smell won't be obvious. Hng!"
"The car's shaking a lot. Ki-woo might notice."
"N-no. Please."
"I'm cumming soon."
Spurt! Spurt!
"Haaah!?"
This time I couldn't hold back and came inside her pussy.
"Ah, what do I do. Now the smell……"
"Just wipe it with wet wipes quickly."
I deliberately opened the window a bit, pretending to ventilate. By the time the smell had faded somewhat, Ki-woo got in with three coffees.
"Here you go, President. Se-jeong, this is yours."
"U-uh. Thanks."
"By the way, Se-jeong. Why is your face so red?"
"I-is it? Maybe because it's hot."
"You're not sick, are you?"
"No. I'm fine."
Ki-woo was clearly enjoying the situation too. Se-jeong looked like she was going crazy with anxiety, which was both pretty and arousing.
In the end, she got scolded in the CEO's office.
"President, we almost got caught!"
"We didn't though?"
"Seriously, why are you like this? Isn't this too much? I really don't want to get caught."
"Alright, calm down."
"Please. I don't want to hurt Ki-woo oppa."
"That's a contradictory thing to say."
"I know my actions are wrong, but…… Haa. Anyway, I'm begging you."
Like I'd stop just because she asked. This was rare fun.
In the afternoon I gave her an even more exciting order. I called Se-jeong in and made her get under the desk. It was basically the same as telling her to suck my cock.
"You're horny again?"
"Yeah. Seeing you makes me really horny."
"You've been complimenting me a lot since earlier. Am I that pretty?"
"Yeah. Extremely."
"Hehe."
She'd been so angry yesterday, but at the word "pretty" she got happy again and took out my cock to suck it.
Slurp— Lick. Lick. Lick.
While she was doing that, Ki-woo came in.
"President, I have something to report."
As expected, Se-jeong flinched in surprise. I grabbed the back of her head and kept making her suck while I spoke.
"Ki-woo, wait a second. Let me look at the documents."
"Yes."
"Stay quiet."
Contrary to my words, I signaled for him to come closer and look under the desk. Ki-woo slowly approached and saw Se-jeong with my cock in her mouth. Not knowing her boyfriend was watching right beside her, Se-jeong diligently sucked me off.


"So, Ki-woo. What should we do about this?"
While Ki-woo returned to stand in front of me and gave his report, I came hard into Se-jeong's mouth.
Spurt—! Spurt!
Gulp. Gulp.
Ki-woo gave a thumbs up. What a funny guy.
Once the report was over, Ki-woo immediately ran out. Probably heading to the bathroom.
"Ah, seriously. Why did you call Ki-woo oppa again?"
"Because it's hotter this way."
"I begged you earlier……"
"He won't find out. Don't worry."
"But if there's even a small mistake…… Really."
"Sorry. Sorry. Instead, come to my place tonight. I'll fuck you all night."
"……"
Even her pouting expression was pretty.
"You don't like that? Fine. Then I'll fuck you until Sunday."
"Really?"
"Yeah. Let's keep it a secret from Ki-woo and have you commute from my place until Sunday."
"I like that!"
"Your mood improved right away."
"You've been taking care of me a lot this week for some reason?"
"Because you're insanely hot."
"Hehehe. It feels good, like I'm being loved."
"Just a moment ago you didn't know what to do because you felt sorry for Ki-woo."
"……I don't know. Hmph."
That day, as promised, I took her home and fucked her to my heart's content. At the company too, I took her whenever Ki-woo was around. Even while anxious, Se-jeong couldn't turn away from my cock.
That was how we enjoyed ourselves a little at the company until Friday. On Saturday we even went on a date while reporting to Ki-woo. I sent him a photo of Se-jeong sucking my cock in a movie theater bathroom.
-Ki-woo. Bitch training complete. She seems like she can't live without my cock anymore. Come tomorrow afternoon. I'll show you.
When I sent that, an extremely excited reply came back.
-Yes! Hyung! I'll come right away!
Sunday was going to be a pretty interesting day.
