Rainbow City

Seokhwa shook off the sudden roughness in his words as if he were bewitched. He held the radio buzzing inside his uniform and said, “Go in first.” Oddly enough, it was Kwak Soohwan who took the first step. Seokhwa stood in front of the cracked pond, rolling the golden persimmon in his hand. He tried to figure out why Kwak Soohwan suddenly got annoyed, but there was nothing more than him complaining about the pain. Seokhwa pressed his throbbing jaw firmly with his hand. It was only then that he realized it had become erect.

***

As soon as night fell, Seokhwa habitually turned on the radio to check if there was any news. He couldn’t fully trust Rainbow City’s broadcasts, but he wanted to know what was happening. Being confined here, which Kwak Soohwan boasted was safe, could be extremely dangerous for him. While not completely immune, he had survived exposure to Adam’s blood. He must have kept this fact hidden from his superiors, and that’s why he was here.

Seokhwa clenched the lukewarm persimmon tightly, rolling it too much. A cure? He wondered if they were lying again. Once again, he focused on the radio, but most of the words were praising the Second Master.

His hair, left unattended, quickly dried as he showered. Seokhwa changed into comfortable clothes and buried himself under the blanket. It was a clean blanket provided by Kwak Soohwan, but the unmistakable smell of mold rose from the mattress. It was pitch dark. After hearing the sound of a few car engines, he heard gunshots. It seemed like they were fired at Adam, who followed the light.

Seokhwa pulled the blanket further up and curled up. Sleeping alone was familiar, but the loneliness of being the only one in this large building came with fear. Seokhwa brought the persimmon he had been holding to his lips. Stones were always comforting, but this persimmon was no less.

Thud!

Seokhwa sat up abruptly at the tremendous noise. Holding the blanket, which was more like a shield, he pressed his back against the wall. Could it be that Adam had come this far? Even though he knew he wouldn’t get infected by Adam, his heart pounded wildly. Thump, thump. He locked the door, and the doorknob shook.

“Major?”

He spat out words from his mouth, but they were too faint for him to hear. As Seokhwa stood up, the doorknob broke with a crunch, and the door creaked open. The light from an incandescent bulb illuminated the corridor and cast a black shadow on the person standing in front of the door. Even with just the silhouette, he could tell who it was. Seokhwa sighed and laid down the quilt after turning on the light.

Kwak Soohwan entered, clad in ordinary pants and a comfortable T-shirt, holding a whiskey in his hand. Silently, he pulled a desk chair and positioned it in front of the bed before plopping down. Seokhwa observed him closely, sipping the whiskey without uttering a word, and then seated himself on the bed. He couldn’t recall witnessing Soohwan drink to the point of intoxication before. However, presently, his eyelids appeared heavy, and his posture seemed more disheveled than usual.

Kwak Soohwan reached out, grabbed a cup on the desk, and poured some alcohol. Seokhwa received the offered glass and spoke, “I can’t drink.”

“I know,” Kwak Soohwan replied, drinking again.

Holding the glass with both hands, Seokhwa’s face seemed a bit tense. Kwak Soohwan, aware of it, continued to stare at him without looking away.

“Dr. Seok.”

He called and then raised the glass to his lips again.

“Would you go to Udo?”

The yellowish liquor in the glass shook slightly.

“Udo?”

“Second Master wants to bring in several doctors under the pretext of developing a cure, and one of them is you, Dr. Seok.”

“I have been stripped of my position.”

“Second Master has given it back to you.”

It seemed like they targeted Seokhwa as he couldn’t be stripped of his controller position.

“Superiors don’t want a cure, they say.”

“If the Second Master can monopolize the creation of the cure, the situation might change. The reason they still haven’t eliminated Adam is to control their security and citizens. If the Second Master can produce the cure, they might even be able to restrain the First. Of course, that’s a story for when it can be made, and they might just use the excuse of bringing Dr. Seok to Udo. There’s a high possibility that the Second Master noticed that Dr. Seok was infected by Adam.”

Are they planning even human experiments, for heaven’s sake? Seokhwa lifted the glass to his lips and then pulled it away. “If we have to go, we have to. If I don’t go, Major, you’ll be in danger.”

As if he had heard an unexpected answer, he tilted his head.

“Superiors must know that Major Kwak is the one who brought me out of the Gwacheon Shelter. But if I don’t go…”

Seokhwa lowered his eyes as if lost in thought. Shadows fell on his thick eyelids, and Kwak Soohwan took a deep breath before clenching his fist.

“I don’t want to lose you. But is Seokhwa really mine?”

Every time he went out and returned to the building, Kwak Soohwan found solace in it. It felt like coming back to a home. While there wasn’t exactly a warm welcome upon return, knowing Seokhwa was in a safe place was reassuring. On the other hand, Kwak Soohwan couldn’t be sure what Seokhwa was thinking. Sometimes it seemed like he wanted to leave, and other times it didn’t. There were clear marks on Seokhwa’s jawline where he had sucked earlier.

Unconsciously, he reached out and cupped the back of Seokhwa’s neck. As he pulled him closer, a slightly wary look appeared in Seokhwa’s eyes. Would making him feel good be appreciated? After all, Seokhwa had shown signs of sensitivity to pleasure before.

Kwak Soohwan, licked the wound he had created with his tongue. Seokhwa’s eyelids fluttered. He raised Seokhwa’s lips slightly higher and pressed them against his soft lower lip, causing Seokhwa’s lips to part.

As Kwak Soohwan slid his tongue, mingling with the faint scent of alcohol, Seokhwa felt like he was getting drunk just from the smell alone. He slid his hand into his shirt and pressed his already stiff nipple firmly with his thumb. As he kissed Seokhwa as if to devour him, the force pushed Seokhwa’s body onto the bed.

“Ah, Major.”

Even as he experienced pleasure, he wondered why they were kissing and entwining their bodies. His gaze, filled with inquiries about their relationship, was fixed on the other person.

“Are we… friends?”

Kwak Soohwan chuckled and let out a bitter laugh.

“That’s the most absurd nonsense I’ve heard lately.”

“So, what are we then?”

Even with a straightforward question, Kwak Soohwan couldn’t easily define their relationship. Instead of an answer, he bit and sucked on the exposed nipple as the shirt rode up.

“Sex… Are we sex partners?”

Perplexed, Kwak Soohwan looked at Seokhwa. “It’s not any kind of relationship, but our bodies intertwine. That’s what the book said.”

“Do you want to be my sex partner?”

Seokhwa looked at Kwak Soohwan with a flushed face and blinked his eyes. “I don’t… know.”

With a smooth and slender movement, Kwak Soohwan slid his hand down his pants, undoing the buckle. As soon as his hand touched the genitalia, Kwak Soohwan rolled the sensitive glans in his hand.

“What about underwear?”

“Normally… I don’t really wear them.”

It’s too hot because of the fever…

Murmuring, Seokhwa felt the sensation of his genitalia being touched. Imagining him without underwear under the lab coat made the atmosphere unexpectedly lewd. Although he usually had a dull face and claimed not to be interested in such topics, Kwak Soohwan, like an animal, bit and nibbled on Seokhwa’s shoulder. Marks were left on the delicate skin, and with each touch of the lips, Seokhwa’s body shivered honestly.

“So, is this a one-night stand?”

He bit and sucked on the exposed nipple while chewing on it with his tongue. Seokhwa blinked his eyes and pulled Kwak Soohwan’s head closer.

“Who puts so much effort into a one-night stand?”

He felt Kwak Soohwan’s breath spread as he lifted his chest, and then Kwak Soohwan firmly grabbed the back of his thigh when he went down. As he reached below, his erect genitalia was fully exposed. The erect genitalia trembled, reaching up to his back. Seokhwa reached out to him in confusion.

As his buttocks spread and a soft sensation came from below, Seokhwa scratched the sheet with the hand that couldn’t reach him. Feeling a sensation he had never experienced before, Seokhwa twisted his body and let out a moan. No, he wanted to twist, but firmly held by Kwak Soohwan, he could only surrender helplessly as the lower part moved rapidly.

Explicit sounds filled the room, and every time it was thoroughly licked, the hole twitched.

“Hmm… this feels strange.”

To the beast below, it seemed like everything below was being devoured. Kwak Soohwan used his tongue to glide up to the sensitive perineum and sucked on the testicles. Seokhwa draped his legs over Kwak Soohwan’s shoulders and pressed his waist against him. Although he pressed his shoulders with his weight, Kwak Soohwan supported firmly, preventing any withdrawal.

Kwak Soohwan, who had taken both sides into his mouth and then released them, felt him smile. He sucked on the firmly erected tip of the rigid genitalia. Seokhwa’s warm mouth, which had felt cool before, now seemed like a hot spring. Seokhwa, with his hands tangled in Kwak Soohwan’s hair, subtly moved his hips.

“What, you want to come inside my mouth?”

He lightly nibbled on the glans. Anywhere was fine. Seokhwa wanted to be quickly embraced and squeezed in a warm place. The chest that had been thoroughly sucked was cold due to saliva but felt hot. Kwak Soohwan placed Seokhwa, who was urging him to suck again, on top of him. Since he was reversed, Seokhwa’s chin touched his substantial genitalia.

“Lower the zipper.”

With misty eyes, Seokhwa undid Kwak Soohwan’s buckle and lowered the zipper. As the briefs were pulled down, the confined genitalia sprang up energetically. The tightly closed hole between smooth thighs was clearly visible, and Seokhwa, unable to contain himself, grabbed his member. As he awkwardly moved, Kwak Soohwan lightly teased the entrance with his thumb.

“Handsome, isn’t it?”

It was a bit odd to call a genitalia handsome, but it was perfectly shaped, as Kwak Soohwan said. Unable to just watch, Seokhwa extended his tongue and licked the precum. As the lascivious taste stuck to his mouth, he swallowed the glans, and Kwak Soohwan exhaled softly.

Leaning against the top of the bed at an angle, Kwak Soohwan spread Seokhwa’s buttocks and grabbed them. Although it scratched slightly as it entered due to the awkward insertion, he endured it. Despite the small entrance not widening further, just sucking on the tip brought a sense of satisfaction. Kwak Soohwan lifted Seokhwa’s waist from behind, embracing him with large hands and covering his chest.

“Haa… why.”

Seokhwa exhaled a disappointed sigh, as if wanting more. Kwak Soohwan inserted his finger into Seokhwa’s mouth, gently rolling against the ceiling. Holding back laughter due to ticklishness, he pressed his finger against Seokhwa’s tongue, inserting it deeply.

“Mmh. MMph.”

Seokhwa’s chest trembled with a fake gag. As Kwak Soohwan comfortingly kissed his ear, he whispered.

Seokhwa turned his head to look at Kwak Soohwan. His eyes, devoid of focus, were clouded.

“…Is this the right thing to do?”

Since he spoke with fingers in his mouth, the pronunciation was unclear. Nevertheless, Seokhwa harbored a lot of doubts.

“This is like a drug.”

Kwak Soohwan couldn’t define how different his and others’ sex styles were. He was just exercising patience to endure until Seokhwa might faint.

Seokhwa nodded slowly and then went down again to grip Kwak Soohwan’s thigh. Lowering his head, he continued to take Kwak Soohwan’s moist member into his mouth, pushing it deep inside. In the process, he compared it to Kwak Soohwan’s firm lower abdomen, reaching up to his erected nipples.

Open up.

Kwak Soohwan gently teased the exposed hole with wet fingers. As tension eased, Seokhwa’s buttocks blushed vividly as he massaged them. Kwak Soohwan put his finger inside the relaxed hole, and when Seokhwa tried to spit out his member, he blocked it with a thrust of his hips.

“Keep going.”

Seokhwa, bewildered, only held onto Kwak Soohwan’s member with a fluttering of his eyelids. The sensation of the opening below was too unfamiliar. A muffled moan escaped from the blocked mouth, and Kwak Soohwan wantonly explored both above and below, making Seokhwa feel like his body was no longer his own.

As one more finger entered, Seokhwa spat out the genitalia from his mouth. He could only moan as he pressed his face against Kwak Soohwan’s thigh and felt the intense friction from the heavily erected member, even reaching his nipples.

“Tight… hm.”

His forced-open lower part was being intensely stimulated. The fingers moving like scissors came close with excessive stimulation to the mucous membrane that had never been exposed before.

“Ah!”

As the finger was twisted, and the pressure applied to the direction of the abdominal skin, a scream erupted.

“Don’t faint.”

His buttocks clenched, and Kwak Soohwan’s breathing became rough. He continued to press and explore inside with his fingers, and the fluid flowing from Seokhwa’s genitalia slowly dripped down to his chest.

As he surrounded the two thighs attempting to escape and twisted his fingers, a moan close to a whimper burst out. The breath scattered outside was hot. As if awakening from a faint state of mind, continuous stimulation from below poured out relentlessly.

“Ah, no… Hoo…”

As Kwak Soohwan slowly withdrew his fingers, the previously widened opening tightened again. He pulled his fingers before the lower part, painstakingly widened, could fully close. Seokhwa’s heavy breaths caused the lower part to expand once more. Running out of patience, Kwak Soohwan, instead of lubricant, spat saliva into the opening.

“Ugh!”

Seokhwa looked at him with surprise, lifting himself up and covering his buttocks with his hands.

Though it seemed like a blaming gaze, Kwak Soohwan didn’t know what the problem was. Still, he apologized briefly. He carefully pulled Seokhwa, who had distanced himself, closer and embraced him. While gently loosening the damp opening, he rubbed his member against Seokhwa’s genitalia. Sweat glistened on his round forehead. Kwak Soohwan pressed his lips to Seokhwa’s forehead and gently laid him down, then climbed on top.

Lifting his legs and teasing the perineum with his large member, the anticipation or tension caused the opening to contract sharply. Bringing the glans forward, it felt as if it was sucking him in.

“Should I put on a condom?”

Although condoms were supplied in the military, they were of poor quality and often tore easily. Suppressing the desire to thrust as it is, Kwak Soohwan whispered to Seokhwa. While softly caressing his chest and teasing below with his member, he asked, “Do you have any?”

“No, I don’t. We need to get one.”

“I won’t hurt you. I’ll be careful,” he tempted, kissing slowly down Seokhwa’s eyes and cheeks. Seokhwa hugged Kwak Soohwan’s shoulders. Though his large body still provided a sense of security, he was a bit frightened, but it seemed okay. It felt good with fingers, and he couldn’t help but look forward to what it would be like with his member. Was this really meant to be so explicit?

Kwak Soohwan raised both legs high and looked down below. The face of the man who always wore a relaxed smile felt cold. However, the heat in his eyes was evident. Holding onto the buttocks, he began pushing in forcefully. Seokhwa’s mouth opened, but not even a sound could escape. Below seemed to be opening so tight it wouldn’t close again.

Hak, haha… Intermittent breaths escaped his throat like there were beads stuck in it. Kwak Soohwan pressed his forehead and exhaled low. Pushing forward with his glans, it felt like he was being sucked in.

“The effect of the libido suppressant didn’t work well and it has been a while since it wore off. Careless moves might lead to losing control. While penetrating deeper, Kwak Soohwan looked at Seokhwa with a lowered face. The resistance seemed to be weakening.

Seokhwa gasped for air, waiting for the stretched lower part to become familiar. Each time the cock penetrated a bit further, he wrapped his lower abdomen around it. Kwak Soohwan was paving the way with his cock where fingers couldn’t reach.

“Ah, ah…”

“I’ll go slowly.”

Though the words were tender, Seokhwa couldn’t hear them well. Nevertheless, it wasn’t just pain that filled him; it felt like oscillating between heaven and hell. As Kwak Soohwan slowly probed inside, then withdrew his waist, Seokhwa bit his lip. When it went out and then came back in, he couldn’t help but open his mouth.

The pace gradually picked up under the slow teasing, and the thrusting became stronger. As the cock vigorously pounded inside, causing him to gag, the shape of his lower abdomen changed each time it went in and out.

“Oh, Major… Inside… Pushing. Pushing out.”

Kwak Soohwan, holding Seokhwa in his arms, captured both the moaning lips and the hazy eyes. The pleasure of having his cock fully engulfed led to the intensification of the act. If this was what ecstasy meant, it would never end with just one time.

Despite the difficulty, he continued to thrust into a particular place inside Seokhwa that responded, causing his body to tremble.

“Ah! Haah… Ugh.”

As Kwak Soohwan pressed against the prostate, a watery fluid spurted from Seokhwa, flowing down from the testicles to the perineum, surrounding the hole. Seokhwa looked up at him, bewildered.

“Why… Haah!”

Continuing to thrust relentlessly, as if Seokhwa would faint, he began to convulse. Kwak Soohwan recklessly teased his cock against the narrow inner walls.

“Feels good?”

“Ah, it’s strange. It’s coming out. Can’t stop it… Hold it.”

Seokhwa grabbed his member, but it was futile. Kwak Soohwan, with a smile that seemed to say something but didn’t, gently removed Seokhwa’s arms and lifted them up.

Regardless of how many times he had penetrated, now Seokhwa accepted Kwak Soohwan smoothly. The shock when the glans hit the hole and thrust up remained, and Seokhwa’s thighs trembled. He couldn’t endure it anymore. He wanted to escape from the stimulating tremors Kwak Soohwan was giving him or maybe lose all reason and become a mindless body.

Kwak Soohwan pushed himself so obsessively that it seemed as if his fixation nature might truly be focused on sex, and he didn’t stop at ejaculation either. Seokhwa remained oblivious to when he climaxed. No, it wasn’t even an ejaculation; his lower region was drenched with a watery fluid. Each time Kwak Soohwan went in and out, there were squelching sounds. Seokhwa wondered if he had lost control due to the stimulation of penetration.

“Stop, Major… I need to… go to the bathroom.”

Seokhwa murmured that it couldn’t go on anymore, but Kwak Soohwan lifted Seokhwa’s body and sat him on top. As the penetration became deeper, Seokhwa, completely soaked below, twisted his body.

“Dr. Seok, you suit my taste perfectly.”

His voice was deeply buried.

“Taste…?”

“You’re very clear.”

With a thrust, he lifted his waist. Seokhwa strained to place his cheek on Kwak Soohwan’s shoulder.

“Dr. Seok, you’re like a fountain bursting with these clear fluids.”

His voice was hoarse.

“What’s that…?”

Well, you do have to know what shame feels like. When Kwak Soohwan laughed, everything beneath, filled with his penis, trembled

“Seokhwa.”

Huh! With him deeply inside, Kwak Soohwan called him. Gripping his waist tightly, he pressed down to prevent any escape.

“Seokhwa.”

Lifting his face, Kwak Soohwan wet his chin.

“Hyung.”

Seokhwa opened his eyes wide, looking down at Kwak Soohwan. While looking up, he extended his tongue, licked the nipple, and sucked it again. It seemed that the violation wasn’t limited to their entangled bodies but also reached their gaze. Hyung, do you like it? Feeling strangely different, Seokhwa tried to push him away with his lower abdomen and fingertips, but Kwak Soohwan intentionally dove in.

His unstable breathing disrupted, and the area below, which had been pounded, seemed completely turned into a genital organ beyond control. He wished he could faint instead, but every time his mind grew hazy, a surge of stimulation flowed through him.

“Haah, it’s hard…”

Kwak Soohwan withdrew his penis and thrust back in forcefully. Ah! A shock followed, enough to push him upward, but he had to endure it to the root as he held both wrists tightly. Goosebumps rose as his sucked chest became more sensitive. His eyes, fixed on Seokhwa, were vivid, unlike the distracted Seokhwa. Moreover, there was fear as he didn’t ejaculate, which was terrifying. It seemed like the wide-open hole wouldn’t return.

“Do you… not ejaculate?”

“It’s because of the suppressant developed by Dr. Seok.”

Blaming Seokhwa for his cock not softening, he felt another expansion as the swollen member penetrated deeply once more. Every subtle movement of his felt significant due to being enclosed by Seokhwa’s inner walls.

Despite the turmoil within, conflicting emotions crossed his mind. As Kwak Soohwan explored places even he didn’t know, rather than embarrassment or wariness, he felt the desire to press their skin together more. He reached out his trembling hands and embraced Kwak Soohwan’s body.

“I ejaculate.”

His muscles trembled as if burned, feeling the shock fully on his palm. He whispered. Kwak Soohwan chuckled as if amused by Seokhwa’s whisper. However, he soon embraced Seokhwa’s body tightly with both arms.

“It’s not as easy as it sounds.”

Now, he was tired and couldn’t hold on anymore. He couldn’t even speak those words, and the strength drained from the hands that were holding tightly.

“I think you need to help me a little if I’m going to cum.”

Kwak Soohwan withdrew his penis from Seokhwa. As he withdrew without warning, the hole quivered with a sense of loss. Only moans came out as the widened interior contracted again. He flipped Seokhwa’s body over, grabbed his waist firmly, and lifted it up. Barely pressing the bedsheet with both arms, a clattering sound was heard. At the same time, something pierced inside.

“Ah!”

Entering from below, he trembled even more as if to say it hadn’t been just a prelude until now.

“Ah! Hoo…”

Entering from behind instead of the usual position was much deeper. He felt like his rock-hard penis was scraping against his inner walls so fiercely that his tailbone felt pushed out. He couldn’t support his body anymore, and his arms lost their strength. His upper body, reaching out its hands, collapsed onto the rough sheet, cheek grazing it. Even saliva dripping from the open mouth stained the sheet. Without releasing the hand holding his waist, he repeated pounding against the hot inner walls.
