Amplifying the Sense of Betrayal #3
The small bench in the park of the officetel complex. I had listened as Sehwa told me everything that had happened with Yu Seunghyeon. Thanks to the tracking monster, I already knew every last detail, but pretending ignorance while fighting back laughter had been absolute torture.
“So… Yu Seunghyeon jerked off to our Twinkle posts, right?”
“I’m not sure. He might not have…”
No, he definitely wrapped his hand around his dick and blew a fat load. I chewed the gum I’d bought at the convenience store. Sehwa suddenly leaned in, kissing me deeply. Her tongue slipped inside and stole the gum right out of my mouth. I watched her casually chew it like it had always been hers and let out a soft snort of amusement.
My hand slid into her dolphin shorts, fingers drifting to the crotch of her panties. Wet. Even the pair she’d taken off before her shower had been slightly stained with her juices—she must have been aching for a while.
Sehwa kept shifting her posture as if my touch felt too good to stay still. Eventually she swung her hips onto my lap and straddled me sideways.
“Feels good, doesn’t it? You’re getting off on the thought of Yu Seunghyeon seeing them. You’ve turned into a total pervert…”
“You… You made me this way.”
She wasn’t wrong.
“I was thinking about deleting the Twinkle account, but watching how much you enjoy it makes me hesitate.”
“I want to keep going… I want to keep doing it.”
“If that’s what you want, then we will. Should we give Yu Seunghyeon a little present?”
“A present…?”
Instead of answering, I studied her plain T-shirt. She wasn’t wearing a bra, so the faint outline of her nipples showed through. I nodded, gently pushed her off, and stood up from the bench.
“Get on the bench.”
Sehwa swallowed hard. She had clearly figured out what I intended. After glancing around to make sure no one was nearby, she obeyed. I raised my phone camera and began directing her.
“Legs together, knees bent. Good… Now grab the hem of your shirt and lift it. No, not the whole chest—just enough to tease a little underboob.”
Sehwa lowered her waist slightly and leaned forward, crossing her arms to lift the bottom of her T-shirt. The soft swell of skin beneath her breasts created an incredibly erotic pose. Add in those plump thighs wrapped in tight black dolphin shorts… The composition was perfect.
Just look at that seductive figure. Who could possibly resist getting hard?
“Jihyeok… This is a little embarrassing…”
She was making cute little nasal moans while clearly enjoying herself. Embarrassed, my ass.

After snapping the shot, I ordered her into bolder poses. This time I didn’t give detailed instructions—I simply told her to do whatever she felt like. At first she took a deep breath as if nervous, then began pulling her waistband down to expose her lower belly, turning around to spread her legs and show off the firm underside of her ass. The way her white sneakers framed her ankle bones, the long straight line of her legs, even the flawless skin behind her knees—every detail was worth savoring.
After taking dozens of photos, I smiled in satisfaction.
“Good. Come down.”
Sehwa hopped off the bench and hurried over to me. I pretended to stretch my legs to calm myself, then placed a hand on her chest. Her heart was racing wildly. She was genuinely excited.
“Let’s go upload these.”
“Okay…”
Back home, we lay on the bed editing the pictures before logging into Twinkle and writing the title and caption.
Sehwa, who had been reading the post over my shoulder, looked dumbfounded.
“When did I ever disobey you? I did everything you told me to.”
“It’s just to make it more stimulating. Let the viewers imagine the rest and jerk off to it.”
She knew perfectly well the message was aimed at Yu Seunghyeon. Her body gave a small shiver as she wet her lips with her tongue.
“Do you think Seunghyeon will see it?”
“Of course he will. You two made up, so there’s nothing stopping him. I bet he’ll watch it openly. Like this, staring at his phone while he…”
I stretched one arm out as if holding a phone to watch a video, then formed a loose fist with the other hand and made an obvious stroking motion in the air. Sehwa’s face twisted into a deep frown and she grabbed my arm.
“Ah… I can picture it now… It makes me want to throw up.”
“Your boyfriend disgusts you that much?”
“It’s not that… He’s just dirty. Seunghyeon isn’t the type to wax carefully like you do.”
My expression hardened.
“What? You saw Yu Seunghyeon’s dick? How would you know whether he waxes or not?”
Sehwa looked up at me, the corners of her eyes lifting in a seductive smile. The look was so lewd my cock stiffened instantly.
“You can tell just from the room. That hotel room was filthy. You know that feeling you get when you walk into a restaurant with terrible hygiene…?”
I knew it all too well—that sticky, unpleasant atmosphere. I had felt it just from the screen; it must have been far worse for her in person.
“So you didn’t actually see it?”
“I have zero desire to see it. I don’t want to. So please don’t get mad at me. Every time you make that cold face, my heart drops to my stomach.”
“You phrased it in a way that was easy to misunderstand. Anyway, I need to punish you now.”
“….?”
Sehwa tilted her head. I rose from the bed and stood beside her head, lifting my phone to film her face. The moment she realized it was a video, her throat bobbed noticeably. Without a word, she stripped, knelt in front of me, and placed both hands neatly on her thighs.
“Shouldn’t you apologize?”
“I’m sorry…”
“More politely.”
“I’m very sorry…”
“What exactly are you sorry for?”
“That…”
Sehwa hesitated. Since the camera was rolling, she couldn’t say my name. There was a perfect title for me. She should be able to figure it out.
Soon her plump lips parted.
“I… met another man… and made… Master… angry… I’m sorry…”
I’d expected her to say “Evening,” but “Master”? She was catching on to the submissive play faster than I thought. All those Twinkle posts where I’d deliberately mixed in the word “Master” must have worked.
I let out a satisfied chuckle. Sehwa’s body squirmed restlessly, as if the sound had set her on edge.
“Master… I…”
“What is it?”
“….Please… give it to me…”
“Say it properly.”
“Please… let me suck your cock…♡”
Sehwa pursed her lips and planted a kiss on my glans with an audible chu. A perfect curtain call.
I tapped the stop-recording button and tossed the phone aside. Even after the camera was off, Sehwa continued acting coquettish. The sight made me lose control; I tapped her face with my cock.
“Hng…”
Every time my cock touched her cheek, she blinked rapidly and shook her ass. She was the very picture of a perfect sex slave. I gave a tiny, almost imperceptible nod.
Sehwa immediately opened her mouth wide and engulfed my glans. Once she had only the head in her mouth, her tongue began teasing my urethra, the tip dipping in and out of the slit repeatedly. Even while focused on serving me, her eyes stayed locked on mine—like a black widow slowly melting and devouring her prey.
To remind her not to get cocky, I gave her cheek a slightly firmer tap. Her head turned a little, and the fierce look in her eyes melted instantly into pure obedience.
“Heup…”
Warm breath from Sehwa’s beautiful nose tickled my cock. She focused solely on the glans, lavishing it with attention. She had sucked me so many times that she knew exactly how I liked it. Her hands remained politely resting on her thighs.
I’ll have to put a collar on her soon.
While my mind wandered, Sehwa licked my glans like it was delicious candy—sucking with wet chup chup sounds, swirling her tongue, tapping every sensitive spot. The combination of the sensitive area and her excellent technique had my lower body reacting after about ten minutes.
I gently gripped the crown of her head.
“Heu…”
Her mouth movements grew softer. The urge to cum that had been rising began to recede, but Sehwa tightened her cheeks, applying pressure to the head. The sensation that had been sinking surged back up explosively.
“Kugh…!”
My face twisted involuntarily. Seeing my expression, Sehwa opened her mouth wide and used just the tip of her tongue to draw circles around my urethra. A clear signal not to cum yet. She wanted to keep serving me.
Her control of pressure and intensity was masterful. She was satisfying me perfectly. After several more minutes of her devoted service, the urge no longer receded no matter how she adjusted her technique.
Since she had dared to toy with her Master, it was only right to cum without warning. The moment she placed my glans against her lower lip and flicked her tongue, I pulled free and unleashed the load I had been holding back.
With a wet byurut, thick ropes of semen splattered across Sehwa’s face.
“Hng…!!”
Startled, Sehwa let out a nasal cry and closed her eyes. The intermittent spurts painted her entire face in a vulgar, obscene picture.
I picked up the phone and snapped a photo of her cum-covered face.
Click!
The moment the shutter sounded, Sehwa began stroking her face with her fingers, carefully gathering every drop of semen into her mouth with meticulous care. Then she swallowed it with an audible gulp.
When I grinned, she brought her lips to my still-hard cock and gave it the usual submissive kiss. She licked every trace of semen from the shaft until it was spotless. Afterward she stood up slowly, went to the bathroom, turned on the faucet, and began washing her face. She even brushed her teeth thoroughly before crawling back into bed and clinging tightly to my side, fiddling with her phone.
Did she not want to go any further today?
“What are you doing?”
Sehwa turned the screen toward me. An adult toy website. The page she had been browsing was full of male masturbators… onaholes.
I frowned.
“Why are you looking at those? Planning to use one on me?”
“No.”
“Then?”
“I read that using your hand too much dulls the sensitivity… so I thought I’d give it to Seunghyeon as a gift.”
My lower body twitched visibly, brushing against Sehwa’s hip. Aha. She wanted to keep going so badly that she was deliberately arousing me.
With a mischievous smile, Sehwa asked, “If I give it to him myself, do you think he’ll like it? Or hate it?”
“Hmm… I’m not sure.”
“Later, if Seunghyeon gets too desperate… can I help him finish with it?”
“Won’t your arm get tired…?”
“He’s a premature ejaculator, so he’ll cum right away, right?”
I snatched the phone from her hand, tossed it onto the table, grabbed her body, flipped her over, and climbed on top. Sehwa spread her legs slightly and continued badmouthing Yu Seunghyeon.
“It would be annoying if it got on my hand… but if I buy one that’s closed at the front, it should be fine.”
“If you help him once, he’ll keep begging for more. You’ll spoil him.”
“Then I can just put him in a chastity belt.”
She was completely serious. She genuinely wanted to help Yu Seunghyeon masturbate—just for the fun of it. Even though Sehwa no longer loved him, she still liked him. In other words, sexual acts with someone she liked would still charge her Device.
Because sexual pleasure with a liked person was how Aether gained power.
If she ever learned that fact, she would torment Yu Seunghyeon even more under the excuse of “charging.”
Seunghyeon… what are you going to do? Your life is about to become truly miserable.
Or maybe you’ll actually enjoy it? Having the girlfriend you love milk you dry?
Either way, just endure it.
As I rested my glans against her slick folds without moving, Sehwa continued in a sweet voice.
“Hurry… Please put it in quickly, Master…”
Let’s just put it in. No more thinking. That’s enough for today.
I shook the complicated thoughts from my head and thrust my cock deep into Sehwa’s pussy.
“Haaang…♡”
Her moan today was far lewder than usual. I felt like I could go another ten rounds. Tomorrow I had to fuck Aram and make use of her… So busy. So very busy.
