L*st and Death

"Ah... rut. I think Baekgyeong's gone into rut."

Isaac, who had flung open the fourth-floor entrance, looked down at Siron trailing behind him. The faint pheromones they'd sensed from the third-floor corridor now rushed out in full force the moment the fourth-floor door opened. It felt heavy and sticky, as if meeting a different air pressure altogether.

The scent of burning rubber, laced with cheap synthetic vanilla. Among all the alpha pheromones Isaac had encountered in his life, Baekgyeong's was one of the most intense—so strong it nearly made him gag.

But Isaac didn’t mind the disgust. Hot blood surged through his veins, muscles reacting on their own. His whole body switched into combat mode, suddenly weightless, as if he’d been dropped into a war zone. A reckless urge rose in him—to snatch one more meaningless life from this battlefield.

"I'll, I’ll stay downstairs. On the third floor."

Siron said it with a pained expression. His face was flushed bright red, and Isaac chuckled quietly at the sight.

Ah, how tragic. What a curse. He wanted to kiss Siron atop the corpses of dead alphas.

"You should have dinner first."

As Siron turned to head back down, Isaac lightly tugged him inward.

"Carne asada’s meant to be eaten warm. It’s a shame if it goes cold."

"It’s fine... I’m fine."

Siron weakly pushed his arm away and stepped back. Isaac looked down regretfully at the bag of carne asada in his hand.

"Then would you do me one favor?"

"F-Favor?"

"You must’ve noticed—Baekgyeong’s rut cycle has begun."

"...S-So?"

"It’s been eight days since he lost consciousness. If rut is starting on top of his septic condition, the physical strain will be severe. He hasn’t absorbed a single nutrient this whole time."

Siron cast anxious glances toward the doorway, where pheromones were spilling out like a flood. Beads of sweat had gathered on his forehead, and his face was flushed as if scorched by coals, radiating heat in sharp huffs. Isaac lightly pulled his arm and led him into the fourth-floor lounge. Siron stumbled behind, trying desperately not to reveal his erection—only to find himself standing outside Baekgyeong’s room.

"Then... what am I, uh, supposed to do?"

Isaac looked down coldly at the space between Baekgyeong’s legs.

"He needs IV fluids. But... to stay on them long-term, a catheter has to be inserted. Frankly, I don’t know if he’s worth the trouble. Not unless you help."

In other words, Isaac would hook up the IV, but he had no intention of touching Baekgyeong’s dick. That task, he expected Siron to handle—insert the urinary catheter himself.

It was, in a way, an opportunity to redeem the public humiliation Siron had endured as “Urethra Siron.” But there was a problem. Had Isaac asked a few hours earlier, he might’ve agreed without hesitation. But now, with Baekgyeong’s pheromones swirling like a tornado threatening to suck him in, it wasn’t so simple.

"I-I don’t know how to do that."

"I’ll teach you."

"I... I don’t think I can. Wh-What happens if I don’t?"

"With an erection, he won’t be able to urinate properly. His bladder will over-expand. If that happens... his already-sliced kidneys could suffer further damage."

There was no way out. Siron wasn’t sure if this was Isaac being cruel for the sake of amusement, or if he was just misinterpreting a rare moment of kindness aimed at Baekgyeong.

"If—if his kidneys get... worse, it’s dangerous, right?"

Isaac looked down at Siron with a grim expression.

"You two knew each other before all this, didn’t you? I don’t understand why you’re hesitating."

This was a matter of life and death. If Baekgyeong died because he “couldn’t pee,” Siron knew he’d be tormented by guilt every time he stepped into a bathroom for the rest of his life.

"Fine... okay."

Isaac gave Siron an unreadable look, then walked over to the cabinet affixed to the wall. After pulling out the necessary supplies, he gently nudged Siron forward toward Baekgyeong.

As he moved, Siron felt the wetness between his legs drip slowly down. His mood plummeted with it. At this rate, he might lose control in front of Isaac under the weight of Baekgyeong’s pheromones.

Like a prisoner led to execution, Siron inched toward Baekgyeong—and froze when Isaac turned on the room light.

What the hell... what is that.

Baekgyeong’s fully erect cock was pitching a tent in his pants. Even through the fog of pheromones, Siron could tell—it was disgusting.

"Let’s start with the catheter."

Unfazed, Isaac laid out the medical instruments on the floor: alcohol, betadine, a syringe, lubricant, distilled water, a catheter at least 40cm long, and other items whose names and uses were a mystery.

But Siron couldn’t focus on any of it. His eyes were locked on the bulge in Baekgyeong’s pants. Hidden within that tent was something filthy, vile—and devastatingly tempting.

"P-Please. Hng."

"'Please' what?"

"N-Nothing, ugh... it’s nothing."

His soaked underwear rubbed against his aching perineum and stiff balls. With a shame-flushed face, Siron bit his lower lip over and over, staring feverishly at Baekgyeong’s crotch.

The disgusting one wasn’t the unconscious man with the hard-on. It was Siron—trapped between life and death—who couldn’t suppress his lust.

Even as Isaac began explaining the catheter insertion, Siron kept losing focus under the overwhelming pheromones.

"The catheter must be inserted two knuckles deep into the bladder—"

"P-Pants, should I—uh, s-should I take his pants off?"

"...Huh?"

Before Isaac could finish, Siron interrupted, panting. Isaac looked at him in disbelief. Siron’s lips trembled, as if waiting for permission.

"Go ahead. Be my guest."

Siron gulped and reached for Baekgyeong’s pants. He’d lost so much weight from dehydration and malnutrition that his pants sagged loose. Siron should’ve felt pity—but his mouth kept watering at the thought of touching and sucking Baekgyeong’s cock.

The moment he yanked the pants down, a thick, rock-hard erection sprang out. Already stained white from repeated ejaculations, the shaft was veiny and swollen like a venomous cobra. The tip grew unnaturally thicker—enough to make Siron’s hole twitch in anticipation, as if just imagining it inside him could turn his insides to mush.

"His pheromones are obscene."

Isaac winced, deepening the furrow between his brows, and handed Siron a wet wipe.

"Wipe him clean."

"Me? I’m doing it?"

Their eyes met in the air. After watching Siron a moment, Isaac grimaced and looked back at Baekgyeong.

"Why not just cut it off? He’s unconscious—wouldn’t even feel it."

"No! You can’t! That’s—absolutely not!"

Siron snatched the wipe from Isaac in a panic. He pulled out several more with a dramatic flourish, but when it came time to actually touch Baekgyeong’s erection, he was overwhelmed with shame.

Like someone hesitating to touch a hot surface, Siron made a few false starts before finally grasping the shaft. It was sticky and burning with fever, so hot it sent shivers down his spine. He slowly began to wipe. The heat of the flesh radiated through his palm. When he felt the pulse throbbing along the thick veins, another wave of slick wetness gushed between his legs.

"Hnghh..."

Shifting his hips as he peeked at Isaac, Siron finished wiping down the shaft. All the while, he kept imagining how much cleaner it would be if he used his mouth instead of the wipes.

Without a word, Isaac grabbed a wad of cotton soaked in alcohol and rubbed it across Siron’s palm. The sharp smell and cold sting should’ve snapped him out of it—but instead, his whole body trembled, and meaningless moans slipped from his wet lips.

"Hmm. I didn’t anticipate this issue."

"H-Huh?"

Isaac picked up the catheter.

"It might be too short."

Siron blinked slowly, comparing the 40cm tube to Baekgyeong’s erection with a dazed stare. He extended his hand, spreading his fingers to measure the length, then cross-checked it against the cock with surprising diligence. After another sharp inhale, he tilted his head uncertainly.

"Baekgyeong’s not... uh, that long."

Isaac gave him a look of utter disbelief and sighed.

"It’s for securing the catheter bag, not because of his length."

Then, as if a solution came to mind, Isaac peeled off his gloves and stood.

"I’ll switch to another one. I have just the thing."

Before leaving, he warned Siron.

"Don’t touch anything. Wait."

"H-How... how long do I have to w-wait?"

Isaac stared hard at Siron’s anxious face and said sternly,

"You’ve been warned. Wait."

Siron lowered his head, unable to meet Isaac’s eyes, and gave a shaky nod. He obeyed like a dog in training, lips drooling from hunger, trembling with the desperate urge to suck. At some point, frustration began to boil over. And as soon as Isaac turned to rummage through the cabinet, Siron threw caution aside and engulfed Baekgyeong’s cockhead with his mouth.

Something brushed the air.

At first, he thought it was just a change in temperature—but no. A strange sensation tingled in his sinuses, awakening something unfamiliar.

Like color suddenly appearing in a grayscale world, Siron perceived a scent—for the first time.

It felt like the concentrated musk of a lust-stained beast. The fatty, animalistic stench hit his nose, followed by a damp, masculine sweat. It was a predator’s scent—one that scrambles a female’s nervous system to trigger arousal.

Then came a sharp, acrid note, like melting plastic, tinged with nausea. And finally, a gentle, seductive sweetness: vanilla.

It was layered. Repulsive, alluring, powerful. Siron couldn’t dissect each note—he just sucked in the scent greedily, trembling with reverence.

He was in shock. Not from touch, but smell.

He was finally smelling pheromones.

Fuck. What do I do. My body changed again.

Something terrible had happened to his body—but Siron didn’t hate it. No, he raged at the fact that he’d lived without knowing this world until now.

"Mmph... nghh, huuh—"

He shoved Baekgyeong’s cock in deep, until it hit the back of his throat. Even with only the head and part of the shaft in his mouth, he could taste it. He coiled his tongue around the bulging veins, snorting Baekgyeong’s pheromones like a junkie.

"Slurp, nghh, mmmh."

"...You’ve got to be kidding me."

A cold voice rang out beside him, and Siron froze mid-suck.

"I warned you to wait."
