The Boyfriend's Hidden View
The next day. While Lee Se-jeong had gone out grocery shopping, Ki-woo arrived at the house.
“Hide the shoes.”
“Where should I hide?”
I led him to the master bedroom. For today, I had bought an especially large wardrobe.
“Get inside and watch from here.”
“It’s huge?”
“I bought one big enough for you to fit.”
“But if the door is closed, will I still be able to see?”
“I drilled some holes. You’ll see fine.”
“Insane. This is insane.”
Ki-woo’s face flushed red. He was trembling with anticipation.
“Don’t be shocked when you see her. She’s a total bitch now.”
“Hoo… I’m really looking forward to this. The pure Se-jeong turning into a bitch……”
“Training her was a bit of work, but she ended up exactly like that.”
“Please start as soon as Se-jeong arrives.”
“Of course. You can’t stay hidden in there forever.”
“Hahaha. Right.”
“Take some wet wipes in with you. In case you feel like jerking off.”
Preparations were complete.
“Wow. I can see everything perfectly, hyung-nim.”
“Enjoy the show.”
“Yes!”
“Don’t come running out no matter how surprised you get by her reactions.”
“Don’t worry. I won’t come out.”
“I’m going to fuck her until she passes out, so come out then.”
“P-pass out? Is that even possible?”
“Yeah. Just watch.”
Soon Lee Se-jeong returned from shopping. I stepped out into the living room, immediately pulled her into my arms, and carried her inside.
“D-Director. After dinner……”
“Right now, I want to eat you first.”
“Heee. You’ve been pounding me all week and you still like my pussy this much?”
“Yeah. So I’m fucking you right now.”
“Okay. Director—no, Master.”
The word “Master” must have startled Ki-woo. Knowing he was watching made me even more excited. Now it was my turn to enjoy myself.
I threw Lee Se-jeong onto the bed and stripped off every piece of clothing. She took hers off without being told.
“Is this an appetizer before dinner?”
“No. This is the main course. Dinner is dessert.”
“Thank you for the high praise, Master.”
“Of course. You’re my bitch.”
“Hehehe.”
Se-jeong spread her pussy open herself.
“Master’s bitch pussy is already soaked. Please come quickly, Master.”

****
‘M-Master?’
The word that came out of Se-jeong’s mouth made my heart race. So she really had turned her into a bitch. They hadn’t even started yet, and she was already smiling while calling him Master.
‘She really……fell. Se-jeong.’
A shiver ran down my spine. Se-jeong had never allowed this with me. She had talked about staying pure until marriage. And now she was calling him Master with that sweet smile.
Betrayal welled up inside me.
‘How could she do that?’
She had ignored every signal I gave her, yet she fell in just two days in Gangwon-do. After that she let him use her like a toy at the company too. But more than the betrayal……I was incredibly turned on. My cock was throbbing so hard it felt like it would explode.
“Master’s bitch pussy is already soaked. Please come quickly, Master.”
Se-jeong spread herself with her own hands. It was too much. I felt like I might get a nosebleed.
Ziiip—
Now I understood why he had told me to bring wet wipes. Without thinking, I unzipped my pants, pulled down my underwear, and grabbed my cock. My hand moved on its own.
‘Slowly. Let’s enjoy this slowly.’
This was the moment I had been waiting for. All I had seen until now were photos at best.
‘She even gave him a blowjob.’
That had been insanely hot, but it couldn’t compare to seeing it in person. Today I would finally see it—my beloved Se-jeong clinging to the hyung-nim she respected most, acting spoiled, drowning in pleasure.
“Se-jeong. Let’s do 69.”
“Huh? Ah, okay! Sounds good.”
“I’ll lie down.”
Hyung-nim lay on the bed and Se-jeong turned around, climbing on top of him.
‘He really is huge.’
When I saw it in the bathroom it hadn’t been erect. Even then it had been massive, but now it looked well over twenty centimeters. That superior physique, handsome face, and wealth……
‘No wonder Se-jeong fell.’
Any woman would shake if she got fucked by a cock like that. Se-jeong took it into her mouth. Hyung-nim licked her pussy in return.
Chuuuup—
Slurp—
Only the wet sounds of them sucking each other filled the large master bedroom. The noises were lewd, sticky, and obscenely loud.


‘Fuck. Fuck.’
I was so turned on I thought I might lose my mind. Because the wardrobe was placed right beside the bed, I could see every movement of their tongues.
“Hnn! M-Master. Using your fingers like that is cheating……”
“Then you do it too.”
“Hnn! You’re so mean.”
Chuuuup! Chuuup!
Se-jeong gripped his cock with both hands and focused on the glans. Her cheeks bulged as she tried to take the large head into her mouth. Hyung-nim stirred her pussy with his fingers before plunging his tongue in and sucking greedily. Watching them work to make each other come was unbearably arousing.
“Haa! Hnn!”
Se-jeong’s body trembled as she came with a small cry.
“I win.”
“I-I’ll make you come too.”
Even after coming, she didn’t take her mouth off his cock. She kept sucking until she finally squeezed every drop of his cum out and swallowed it all.
Gulp. Gulp. Gulp.
‘She’s……drinking it so naturally.’
How many times had she swallowed it while I wasn’t watching? She looked far too used to it.
“Foreplay’s done. Time for the main event.”
“Yes. I’d like that.”
“I want to try a certain position.”
Hyung-nim suddenly stood up beside the bed and pulled Se-jeong up by her wrists.
‘……Huh?’
The position was perfect from my angle. Se-jeong was facing the wardrobe while he stood behind her.
“Master. Are you going to put it in from the start?”
“No. I’m going to hold you like this from behind.”
Thrust—
“Hnnng!”
Insane. He was crazy. While holding both of Se-jeong’s arms, he drove his cock straight into her. It was like a standing rear-entry position. Se-jeong’s back stayed straight as she took his entire length.
‘H-He’s insane.’
This was too much. I couldn’t just sit there watching. He had clearly arranged this pose for me. Thank you, hyung-nim.

****
Ki-woo. Are you watching properly?
I deliberately positioned Se-jeong’s body toward the wardrobe so he could see and hear every expression and moan clearly in this angle.
‘Enjoy it, Ki-woo.’
I was going to enjoy it too. Knowing he was watching made me unbearably aroused.
“Hnn! Your cock feels even bigger, Master. Hnnng! It’s so deep!”
Se-jeong seemed to sense my excitement and moaned louder. The wet slapping sounds echoed heavily.
“Hnn! Haa! Why are you so turned on today? You’re being so rough!”
It was hard to stay rational. I had fucked Se-jeong countless times, but knowing Ki-woo was watching made it taste even sweeter. A sharp, burning pleasure took over my body.
An amusing thought occurred to me.
“Se-jeong.”
“Hnn! Y-Yes, Master.”
“Can you see the wardrobe in front of you?”
“Yeees!”
“Imagine Ki-woo is inside it.”
“Hnnng!?”
As expected, Se-jeong clenched down hard at the sense of betrayal. The tight, web-like grip made me squint.


“What, just imagining it feels that good?”
“Hnn! It’s not that, haa!”
“Why? Feeling guilty?”
“Hnn! Yes!”
“But you already decided to be my bitch. You decided to keep getting fucked behind Ki-woo’s back, didn’t you?”
“Th-That’s right! Hnn! I decided to be Master’s bitch!”
“Then report it while imagining Ki-woo is watching.”
“Th-That’s! Haa!”
Ki-woo. Are you going crazy? Sorry. But this feels too good to stop. You’re enjoying it too, aren’t you?
Thrust— Slap— Slap—
“Go on. Say it.”
“Hnnng! Ki-Ki-woo oppa! I’m sorry! I’m cheating behind your back! I’ve become Master’s bitch!”
“You never even gave him your pussy once, right?”
“Hnn! That’s right!”
“So you gave that virgin pussy to me instead.”
“Haa! Hnn!”
“You must feel really guilty.”
“Haa! I’m sorry, oppa! I even gave away my virginity! I-I’m……Master’s bitch!”
I wonder what Ki-woo is thinking right now.
*Se-jeong. Ah. Se-jeong. You like hyung-nim that much? Your face……looks so turned on. You really look happy. So……fucking hot.*
*If this keeps going……he’ll really steal you away. But……I can’t stop. The stimulation is too strong. I want to keep watching. I’m anxious, but I’m so turned on. Haa. You’re enjoying it in your own way. I think I can give you a little more stimulation.*
I lifted one of her legs so he could see exactly where my cock was entering her.
Thrust— Thrust—
“Hnnng!?”
“Ki-woo. Are you watching? My cock is buried in your girlfriend’s pussy right now.”
Don’t answer, Ki-woo.
“This pussy tastes fucking amazing. Sorry for fucking her behind your back.”
“Hnn! Oppa! I’m sorry too!”
Se-jeong, already a slave to the guilt, moaned while apologizing.


“I’m the only one who gets to eat the pussy you never gave him. I’m really sorry. But I promised to buy you a house, remember? Be satisfied with that.”
“Hnn! O-Oppa! Let’s live happily in that house!”
“Oh? Se-jeong. You’re not going to betray Ki-woo?”
“Yeees! I won’t!”
“You’ll stay with him?”
“Yes!”
“While being my bitch?”
“Yes!”
“While secretly cheating for the rest of your life?”
“I-I’m already Master’s bitch!”
“Isn’t that even more of a betrayal?”
“B-But! I still love Ki-woo oppa too!”
Half of that was sincere. The other half was for the thrill.
*Thank you, Se-jeong. Really. Yeah. I want to marry you too. I love you. So much.*
Ki-woo seemed quite moved by her words.
“Good. Then Se-jeong, I’ll come fuck you in secret on your wedding day.”
“Hnnng! Th-That’s!”
“You don’t want that?”
“N-No!”
“And during the honeymoon, I’ll fuck you while Ki-woo is asleep.”
“Haa! D-Don’t!”
“Wouldn’t it be even more thrilling if I fucked you right next to the bed where Ki-woo is sleeping?”
“N-No! I don’t want Ki-woo oppa to find out!”
That really would be terrifying. She had been scared even in the car. Same bed? On the wedding day? But these words weren’t really for Se-jeong.
‘Ki-woo. You’re okay with that, right?’
*W-Wedding. And during the honeymoon……whoa. Fuck. That would be so hot. Then until then……I shouldn’t tell Se-jeong, right?*
*No. Should I tell her……and enjoy it together? Should I invite hyung-nim on the honeymoon too? But……if I tell her, will Se-jeong forgive me? What if she feels betrayed by me? I……can’t live without Se-jeong.*
A little anxiety could be handled by me. I lifted Se-jeong’s remaining leg as well. Now she was properly held in a full standing position. He would be able to see my cock buried inside her pussy clearly.

“Hnnng! Th-This position is too hard!”
“Lee Se-jeong. Listen carefully. I enjoy fucking you in secret. So never break up with Ki-woo.”
“Hnn! Y-Yes!”
“No matter what happens, don’t break up. That’s an order from your master.”
“I-I understand! I don’t want to break up either!”
“If you break up, you won’t get this cock anymore. Got it?”
“Yeees! I’ll remember!”
This should put Ki-woo at ease. He was probably thinking “Thank you, hyung-nim” without me even needing to search. Thanks to him, I was enjoying a delicious meal too.
Ki-woo. Wedding and honeymoon, huh. I really wanted to follow along and eat properly. I should hurry up and make them get married soon.
“Hnnng!? M-Master! I-I’m……!”
“You’re about to come? Good. Come.”
Thrust thrust thrust thrust—
It was only natural to show Ki-woo Se-jeong’s orgasm. I pounded her roughly and relentlessly, driving her toward climax.
“Hnnng!?”
“I’m coming inside!”
“Yeees! Come! Fill Master’s bitch pussy!”
Ki-woo. Did you hear that? She’s been trained this well.
“Khh!”
Spurt spurt spurt—!
The pleasure was too intense to hold back. I poured everything into Se-jeong’s pussy.
“Haaaaang!”
Se-jeong screamed like she had lost her mind, then slumped in my arms, panting.
“Haa. Haa. Haa.”
Trickle—
When I pulled out and lowered her, she immediately sank to the floor, catching her breath. My cum leaking from her pussy looked beautiful, as always.


Thanks to her, I ate very well. Ki-woo. But we’re not done yet. Keep enjoying yourself in there. I want to go even crazier.
“What did I tell you to do when we’re finished?”
“C-Clean up.”
“Right. Do it.”
At my command she immediately took my cock into her mouth and sucked. Now, what pose should I show him next, Ki-woo?
