DP Side Story Episode 5
by BrieDeep Pivot Side Story, Episode 5
Midday temperatures were now a little too warm to call it spring anymore. As Seo-joon browsed through the dressing room, his eyes landed on a shopping bag tucked in a corner.
“……”
Inside was Yeon-woo’s school uniform—the one Seo-joon had carefully prepared, thinking it might be the last time he’d ever get to do so, just before the final Gate incident. It had come home with them, packed up by the Center when Yeon-woo was discharged. And now, seeing it again stirred something in him.
He placed it deep in the back of the closet. He’d keep it safe. Maybe when Yeon-woo turned thirty, he’d pull it out and have him wear it again, just for fun.
Would that day ever really come?
Would there ever be an age when a school uniform didn’t suit Cha Yeon-woo? Even if he were old and wrinkled, Seo-joon was sure he’d still see him as that bright, green-eyed baby.
A faint smile curled Seo-joon’s lips. The thought was silly… and sweet.
He picked out an outfit for Yeon-woo, then chose his own, and stepped into the living room—only to find Yeon-woo just coming in from the front door, holding a package in his hands.
“Lieutenant, what’s this?”
Seo-joon shrugged with a puzzled look. Ever since he’d technically “come back from the dead,” he’d started ordering things—maybe out of impulse, or maybe from a renewed zest for life. Either way, deliveries had been arriving almost daily.
Yeon-woo brought the box to the kitchen table and inspected the label. It was addressed to Seo-joon, but the shipping invoice was all in a foreign language, and he couldn’t make heads or tails of it.
He opened the packaging—complete with a manual and a warranty—and finally pulled out the contents.
A strange-looking silicone ring.
Yeon-woo held it in his hand and turned to Seo-joon with a completely blank expression.
Seo-joon blinked, then casually replied.
“Oh, that. It’s for you, Yeon-woo.”
“What is it?”
Seo-joon sighed inwardly. He hadn’t exactly expected Yeon-woo to recognize it on sight, but this really wasn’t the kind of item he wanted to explain… especially not in broad daylight before an outing.
“…A bumper.”
“Huh? Like… a car bumper?”
That almost made Seo-joon drop his composure. He exhaled slowly to keep from losing it.
“Not a car bumper. A cock bumper.”
He said it calmly, without hesitation.
Yeon-woo blinked.
Tilted his head like he’d just heard a hallucination.
So Seo-joon repeated:
“A penis bumper. You wear it. On your dick.”
The reaction was instant.
Yeon-woo’s face flushed crimson, blooming with secondhand embarrassment. His wide blue eyes darted left and right like he was trying to flee from the meaning of what he’d just heard.
His expression said: Why would anyone…? Why would someone put something like a “bumper” on a person’s body? What horrific, unholy purpose could that possibly serve?
“It’s kind of like… a speed bump.”
Seo-joon added the explanation quickly, before Yeon-woo could spiral into any truly bizarre misunderstandings.
“A… speed bump…?”
Yeon-woo repeated the words slowly, but his eyes were darting everywhere—still completely lost. His brain clearly hadn’t caught up yet.
Tap, tap.
Seo-joon finally gave in and demonstrated, lightly tapping his closed fist into his open palm.
“It’s safer when there’s a set limit, right? That way we don’t have to stop and check every time. I still need to adjust to taking you in, and until then, this just helps. So let’s use it… just for now.”
“……”
Yeon-woo stared blankly at the gesture, like he was watching a magic trick from another planet. A few seconds later, realization slowly dawned—ah… aaah…—followed by a heavy, embarrassed sigh.
The history of sex was long, and humankind had always been a tool-using species.
Seo-joon, his expression somewhere between serene and resigned, simply watched his ever-learning, ever-surprising lover in silence—like a monk observing a disciple on the slow path to enlightenment.
Yeon-woo’s face had gone so red, it looked like one poke might cause it to explode. It was the kind of expression that made Seo-joon feel two completely opposing things at once—protective affection and a wicked urge to tease him until he broke.
“Y-yes… I understand what you meant.”
Yeon-woo nodded furiously, head down, his whole crown tinted a soft pink. Even his scalp looked embarrassed. Just watching that reaction for a few seconds was enough to stir something deep and irresistible in Seo-joon.
“…You know, Yeon-woo,” he said, completely straight-faced.
“your size is kind of… difficult.”
Not a hint of humor in his tone—dead serious.
“I couldn’t find anything that fit, no matter how hard I looked. I had to order it custom from an overseas site—it was a whole ordeal. Said I had to measure while you were hard, too.”
Yeon-woo, who had been nodding non-stop like one of those bobblehead car dolls, suddenly paused and looked up at him.
“W-when did you…”
“Back at the hospital.”
His eyes, filled with suspicion, darted around, unable to settle. Seo-joon replied casually, like it was no big deal.
“I measured it while you were asleep.”
“……”
“Didn’t take much—just a little sucking and you were already hard.”
Yeon-woo opened his mouth like he wanted to say something, but only managed to look utterly scandalized. Seo-joon, meanwhile, quietly chuckled to himself.
Not that he’d actually sucked him off, of course.
Yeon-woo had always been, well… vigorous. Just the lightest touch was enough to get him going—so even while sleeping, that youthful vitality didn’t go anywhere.
“W-while I was asleep…?”
Yeon-woo blinked slowly, dazed. Seo-joon tilted his head with mock innocence, feigning offense.
“Why so shocked? You measured my finger size when I was asleep too, didn’t you? Without asking.”
Measuring someone’s finger size in their sleep and measuring their cock size? Absolutely not the same thing—and yet Seo-joon had the audacity to act like they were.
Yeon-woo’s entire face, all the way up to his scalp, was now a glowing, embarrassed red.
“…You’re seriously such a weirdo.”
What he really meant was something closer to “You’re an irredeemable pervert,” but the words came out softened, rounded, reshaped into something sweeter.
Seo-joon widened his eyes, feigning shock.
“What? Is it really that strange to secretly suck your boyfriend’s cock?”
He cupped Yeon-woo’s jaw firmly, the warmth of his skin pressing into his palm. Seo-joon leaned in, kissing over his lowered eyelids, the bridge of his nose, the lips pouting ever so slightly in protest. Each kiss was sharp and scolding, as if punishing him for being too cute.
As their bodies naturally aligned, Seo-joon slipped a thigh between Yeon-woo’s legs, pressing close.
“And yet…”
He smirked against Yeon-woo’s lips.
“You’re the one getting hard just hearing that.”
As Seo-joon pressed his thigh gently against the bulge between Yeon-woo’s legs, a short, heated breath escaped from between Yeon-woo’s lips.
“You imagined me going down on you just now, didn’t you?”
Seo-joon whispered sweetly, lips brushing softly over Yeon-woo’s like a tease.
“…I don’t know.”
Yeon-woo mumbled into the onslaught of kisses, quietly offering up his face as if surrendering.
“Why would you do something like that in secret…? You should’ve woken me up. Something like that… I want to know too…”
His soft protest was so earnest and shy that Seo-joon couldn’t help it—he burst out laughing and pulled him close in apology.
“I’m sorry.”
Seo-joon said, smiling.
“But let’s be honest—if I had woken you up, we probably would’ve done a lot more than that. And we both know that wouldn’t have been okay… in a hospital room.”
Cha Yeon-woo was the type of person whose emotions showed clear as day. No poker face, no ability to hide a thing.
If a researcher had come in to check on his spiking vitals, Yeon-woo would’ve outed himself on the spot—face flushed, eyes dazed, practically confessing “I was having sex just now” without ever needing to speak.
And even now, it was obvious. His eyes and the tips of his ears burned red; his whole body flushed with heat. All from one line—I sucked you off while you were sleeping. It was honestly impressive how reactive he was.
“…Next time.”
Yeon-woo mumbled, voice small but firm.
“you have to wake me up.”
“So… that sounds like you want me to do it again.”
“……”
He didn’t deny it.
Which meant, of course, he didn’t hate the idea.
Well, Seo-joon thought, he did say before he liked being touched in his sleep… And now, with no more watchful researchers around, maybe one day it really wouldn’t hurt to try.
He pictured it vividly—slipping Yeon-woo’s warm, sleeping cock into his mouth, sucking him to full hardness, carefully sliding in without waking him, and then rousing him mid-thrust.
What kind of expression would he make?
Seo-joon grinned and pulled Yeon-woo’s lips into his own, sucking gently.
Their eyes met for the briefest moment.
Yeon-woo quickly looked away, lashes fluttering down like a folding fan, trembling slightly as they shielded his gaze.
That face—so helpless and soft and vulnerable—it always collapsed something inside Seo-joon. Every single time.
…Alright. That’s enough teasing.
They had plans. Seo-joon didn’t want to leave his poor, flustered lover feeling cornered before they even made it out the door.
“Let’s get ready to head out, Yeon-woo.”
He gently tousled Yeon-woo’s hair, turning away with a calm tone. But just as he was about to step back, something tugged lightly at his sleeve.
Seo-joon turned his head instinctively—and met Yeon-woo’s gaze.
“……”
Their eyes locked in midair. For a heartbeat, Yeon-woo held it, steady and unflinching. But only for a moment. Then, unable to keep it up, he looked down and slipped something into Seo-joon’s hand.
“…Um. This…”
Seo-joon looked down at what he’d been given—the penis bumper.
Yeon-woo gave his hand a tiny, hesitant pull.
“…Can you teach me how to use it?”
Seo-joon bit down hard on the inside of his cheek, something fierce and overwhelming blooming in his chest.
“……”
Had he not caught himself, he might’ve actually laughed—like some twisted pervert uncle.
Ten minutes. Fifteen, tops.
He glanced reflexively at the clock on the wall, already calculating how long it would take.
And that’s when it hit him.
Like a brick to the face: his very first brush with true, unfiltered self-reflection.
He was teasing a younger lover, savoring every innocent reaction with dark delight. And even now, he was fantasizing about pinning him down, drawing out sweet cries until he was in tears. If that didn’t make him shameless, what else would?
Never before had he stopped to really think about it.
Never examined it too closely.
But now, with terrifying clarity, he realized—
He was an absolute, first-class degenerate.
…No. No, actually—
This is all Cha Yeon-woo’s fault.
That damned boy was just too temptingly sinful for his own good.
“L-Lieutenant… ngh…”
Yeon-woo’s hands fumbled, lost, clutching at Seo-joon’s hair—then releasing it just as quickly. His voice trembled, scattered, muffled by the hands now covering his face.
“I-I didn’t mean for it to… go this far…”
But the cock in Seo-joon’s hand said otherwise, twitching with interest. A clear bead of pre-cum gathered at the tip, catching the light. Seo-joon flicked his tongue, lapping it up with practiced ease, then looked up.
Yeon-woo, peeking through his fingers, locked eyes for a split second—only to immediately squeeze them shut again with a flustered groan.
“Ugh…”
“What was I supposed to do, when you’re this hard already?” Seo-joon replied shamelessly.
He’d gone down on him under the most ridiculous excuse—that Yeon-woo was too big, and he needed to apply lubricant properly. A complete and utter lie. But a successful one, because here he was, already on his knees.
“I’ve always thought this, but—”
“I-It’s so embarrassing… it’s so bright in here, and y-you keep looking at me like that, don’t… ah…”
“And honestly, Yeon-woo… even your cock is ridiculously pretty.”
