Side Story Chapter 3

His suit trousers were so tight around his thick thighs that you could see the shape even at a glance. It wasn’t the first time Taeheon got hard in situations Yaein couldn’t even guess, yet it still puzzled her. What on earth about her excited him this much?

When she placed her hand over the bulge, its size pressed against her palm in a stark, unmistakable way. Her heart raced, blood surging to the tips of her toes.

“Should I take care of it for you?” she asked hesitantly. 

“Like you did… with your mouth.”

Flushing bright red, she added the clarification. Taeheon’s eyes widened slightly. Once his surprise passed, his gaze darkened, heavier with desire than before.

“S*x in the office is off‑limits, but oral s*x is okay?” he teased. Yaein dropped her eyes; she had no real answer if he asked what difference it made.

“I just… taking clothes off in a place where people come and go… it’s embarrassing,” she mumbled. 

“Fair enough. I can undress you anywhere you like,” he said. 

“You’re the one who said it was okay,” she shot back.

“Of course. Just tell me when,” he replied easily. 

“Shall I take them off now?”

He tugged his tie downward, unbuttoning his shirt from the top. Yaein’s gaze fixed on his hands; she swallowed hard. When she didn’t stop him, he continued undressing, undoing the last button and reaching for his belt buckle.

“Stop!”

At last, she raised the white flag. 

“Please stop.”

She’d seen her husband n*ked plenty of times but watching him strip in an office with huge windows was too much.

“I haven’t even taken everything off yet,” he said, playful but obedient, letting his hands fall still.

“So, no s*x, no stripping, but oral is fine,” he summarized, half‑teasing. Just hearing him put it that way made her cheeks burn; Taeheon always enjoyed her reactions.

“Should I button up again?” 

“Don’t tease me.”

How should she do this—what position? She decided it would be easiest if he sat. Guiding him to sit back on the sofa, she was about to kneel between his legs when he stopped her.

“Hold on.”

He slipped off his suit jacket and spread it on the floor. 

“Don’t kneel on the bare floor. It’s cold.”

And then, even while Yaein was sitting, she didn’t even forget to hold his arm. 

When Taeheon sat down atop his suit, he felt a strange sensation. 

Yaein knew very well the cost of a suit tailored exactly to fit—it was by no means something you’d use as a mere cushion. 

Although it was Yaein who knelt, Taeheon was even more cautious, as if worried that something might get hurt; his inability to fully relax and sink into the sofa was almost comical, prompting Yaein to let out a small laugh. 

“Sit properly.”

Even when he tried to push his knees away, Taeheon couldn’t fully settle into the seat; instead, he kept watching Yaein. 

“Shall we just stop?” 

“……” 

Taeheon opened his mouth for a moment, then simply closed it. 

It seemed as if he didn’t want to stop, yet at the same time, he was reluctant to continue. Now that he could clearly read his husband’s inner feelings, Yaein felt eager to do something she’d never dared before. 

The zipper on his suit pants had come undone. Carefully, he pulled down his drawers and wrapped his g*nitals with both hands. 

“Why did you suddenly feel like doing that?” 

His voice, deep with s*xual desire, softly caressed the fine hairs by her ear. Listening to Taeheon’s excited sounds naturally set her body ablaze. 

“Because you always do it…” 

Taeheon’s caresses were tender and prolonged. Whether with his hands or his mouth, he spared no effort, causing Yaein to moan. 

Though she could never do it as well as Taeheon, she wanted to at least imitate him. 

When she leaned in closer, the closeness made her recoil once again. Even if she were allowed to do it on her own later, she’d never feel as frightened as she did now. 

“Phew…”

Even the mere touch of his breath made Taeheon let out a long, agonizing sound. 

Yaein hesitantly pressed her lips to his gl*ns, finding the hot, pulsating sensation unfamiliar. When she tried to open her mouth wide to take him in fully, it felt completely different from merely touching him. Even after only half had been swallowed, her jaw already ached painfully, and saliva pooled beneath her tongue. 

No matter how much she tried, she couldn’t seem to swallow him properly—she was tense with worry that his teeth might accidentally scrape her and cause injury. 

Watching Yaein clumsily lick and then spit him out, Taeheon smiled. A mix of lingering, intense desire and a tender, amused smile intermingled in an almost incongruous way. 

“Stop it and come up.” 

Perhaps she had never really expected to be able to suck him off so quickly, as her response came almost immediately. 

“Um…” 

Yaein, shaking her head, eagerly took him back into her mouth. Though her lips tightened, and it became difficult to breathe, she managed, somehow, to take him deeper than before. It felt as if a heavy weight pressed down on her tongue, and saliva moistened her lower lip. 

“Ugh, haah. Ah…”

Heavy panting rose from above. That moan of Kwon Tae-heon… 

A hazy pleasure flooded into his oxygen-deprived mind. Yaein moved actively—she wanted to keep Tae‑heon panting. 

When she bowed her head, his gl*ns pressed against her throat—even though she hadn’t swallowed him completely, it did. 

In the end, she couldn’t hold out. Yaein pulled her head back and coughed. 

Tae‑heon quickly scooped Yaein up. The crumpled suit jacket was dragged off the floor and tossed aside. 

“Are you okay? Should I get you some water?” 

“Uhh… I’m okay…” 

Barely whispering, Yaein buried her head into Tae‑heon’s chest. Ah, really. 

“Why are you trying to hide?” 

“…I feel it’s too shameful.” 

“Too shameful?” 

Yaein glared at Tae‑heon in an amused tone as he mimicked her words. Tae‑heon even seemed to enjoy the look in her eyes. 

“I liked it.” 

“…” 

“I might have liked it so much that I could have died if we’d gone further.” 

“Don’t tease me.” 

“I’m serious.” 

Before she could protest, Tae‑heon captured her lips in a kiss. His tongue slid in, licking her mucous membranes with a kiss that promised pleasure. Holding her head firmly so she couldn’t escape, Tae‑heon kissed her persistently, then paused and pulled his lips away. 

“They’re mine, but they taste awful.”

Expressing his feelings, Tae-heon teasingly sucked on Yaein’s lips. In disbelief, even while catching her breath, Yaein managed a little laugh. 

“You… your lipstick smudged on your lips,” she said. 

“Yeah. Your lipstick even got on my d*ck,” Tae‑heon replied, pointing at the rosy marks imprinted on a pillar. 

“It looks like there’s even a record of how far you sucked,” he added. 

“Ah, really. What should I do…” Yaein murmured, her whole body heating up with embarrassment—a feeling entirely her own. Tae‑heon proudly revealed his wet member.   

“It looks like a territorial mark, and it’s nice,” he said. His playful tone was infuriating, yet as a husband he never seemed to tire of teasing her. 

“But I’m not dead yet,” he added. 

Tae‑heon then guided Yaein’s hand downward. When he gripped it—firmly as if to hold something imposing—his throat tightened. For some reason, it felt larger than when it first touched her mouth. Every time he faced his husband’s vigorous s*xual desire, he felt overwhelmed.   

“What are we going to do about this?” he asked. 

As if reading Yaein’s inner thoughts, Tae‑heon’s voice deepened with laughter. 

“You have to take care of it somehow.”

“Really, when did you become so skilled at squeezing?” 

“You’re the only one who can do it. Please.” 

Tae-heon murmured as he kissed Yaein’s earlobe. His disheveled hair, streaming onto his forehead, added to his youthful look. It was a sight he’d have loved to present as evidence to Gyeongju—Tae‑heon had indeed become remarkably affectionate. 

For Yaein, there was no choice but to submit. 

“Just once,” she whispered as she spread her knees, allowing a large hand to slip inside her thigh. 

His fingers crawled over the damp flesh, so wet it clung like a thousand droplets to skin, while Tae‑heon, teasingly, licked Yaein’s cheek as he stroked the slick, aroused spot. 

“While sucking c*ck, you got this wet? Impressive.” 

The inside tightened at this not-quite-praise. Yaein could feel every ridge of his fingers clinging to her. 

Tae‑heon pursed his lips. His jaw muscles tensed sharply and became pronounced, and a faint, delicate sound could be heard. 

Even the already slick v*ginal walls grew abundantly wet, and the water dripping from Tae‑heon’s hand along her skin was embarrassingly noticeable. 

“There’s really a lot of fluid,” he said, spreading two fingers inside to produce a sticky sound. 

“What if you even get the office sofa wet, honey?” 

Yaein shook her head, unable to reply. Although she loved her husband’s voice, sometimes during s*x she wished she could keep quiet. 

“I’ll just stop it for you.” 

A massive, *rect column of flesh, with a noticeable fissure that he lightly tapped, split open its soft layers, and the sticky slit embraced the tip of his c*ck. 

“As expected,.” 

Tae-heon panted in an even deeper, husky tone than before. 

“You really suck it down well. So don’t be disappointed, ha… f*ck.” 

Tae-heon closed his eyes tightly and then opened them again. It was the face Yaein adored—a drunken expression. 

Even the overwhelming sensation of their confined space widening and their mucous membranes clinging relentlessly became bearable as long as he could see that face. 

Blocking Tae-heon’s mouth with her lips, Yaein wrapped her arms around his back. Their entwined bodies trembled violently.

“This is why I told you we shouldn’t do this outside.”

Yaein rolled her eyes as she picked up her bag and stood up. Taeheon shamelessly followed her like a well-fed animal.

After making love in his office, they had to spend extra time cleaning up in the small bathroom inside the office before finally being able to leave work later than planned. The cool, minty taste lingering on her tongue helped cover up the embarrassment of their earlier activities.

“I liked it. I wanna do it again sometime,” Taeheon said, brushing the back of her neck with his fingertips. The soft hairs stood on end, and when Yaein flinched, his amused chuckle followed.

Hopeless. She sighed and pressed the elevator button.

Inside the elevator, one of the employees was already present. When he saw Taeheon, the employee flinched, gave a hasty greeting, and tried to exit the elevator. It didn’t seem like it was his intended floor.

“Kim Hyungseok,” Taeheon called out abruptly.

“Yes, sir,” the employee stopped immediately, just as he was about to pass by Yaein.

“Didn’t I tell you this building is non-smoking?”

His voice, though quiet, carried a chilling edge.

Caught between Taeheon and the employee, Yaein’s eyes met the latter’s. She realized why he seemed familiar—it was the same employee she saw downstairs who had begged her not to mention his smoking.

Her lips parted in surprise.

“Why are you looking at her? I’m the one talking,” Taeheon said coldly.

The employee quickly averted his gaze, but it was already too late—Yaein felt embarrassed.

Now it really looked like she tattled on him.

“Darling…” she began.

Yaein grabbed Taeheon’s arm. 

“He might’ve just had it in his pocket without smoking it.” 

“And you think that explains him walking around reeking of smoke?”
