Smut warning!

*****

The minutes ticked by, but Wooyoung's muscles couldn't relax from their tension. His fingers were cramped around his gun, ready to shoot at anything inside the cave that as much as twitched. Every second was a torment, and his head hurt from straining so hard. He traced the fouls' steps in his mind and listened to their ragged breathing as they stood idle, minds blank before their next move. Instinct drove them, so waiting until that instinct switched from hunger back to sleep was agonizing.

Wooyoung didn't dare as much as gulp. He could feel the heat of San's body through his clothes, but he didn't have the mind to complain about it right now. Their survival was on the line.

It felt like an eternity passed until the fouls finally returned to their lair. They must have infested the rest of the cavern and snatched those who came here for supplies. As they trudged away to lie in wait for the next intruder, Wooyoung exhaled. Soon, the caverns were silent, yet not abandoned.

"Let's go back to Mingi. As quietly and as fast as we can. And then get the fuck out of here." Without more people to defend them, Wooyoung wouldn't try to relocate the crates.

He twisted his head to find San in the darkness of the cave. No light flickered on, and no response sounded from him. Only his ragged breathing hit Wooyoung's nape.

"San?"

"Give me... a second."

Startled by how ragged he sounded, Wooyoung sniffed. No scent of blood. Just the lingering stench of rotting meat the fouls carried along. They didn't have any pheromones that set off San, right? Would he attempt to kill Wooyoung in their makeshift hideout?

Wooyoung twisted his back to scrutinize the other raider, but he froze once more when San stifled a groan.

It took Wooyoung an embarrassingly long time to notice the raging hard-on pressing against his hip.

"O-Oh," he made with little intelligence. An awkward silence spread between them. Wooyoung couldn't relax, but neither did he have the patience for this.

"What the fuck? Is this the time and place?" He hissed and San jostled their bodies as he jerked up his head. His bulge dug into Wooyoung's flesh, but thankfully, no one could see his mortified blush.

"You were basically riding my dick with all the grinding you did while drawing your gun!" San defended himself. Wooyoung scoffed as quietly, yet maliciously, as possible.

"So you get hard? It seems I didn't make my boundaries clear. Let's get out of here so you can jerk off in your room." Wooyoung wouldn't let go of his gun until they were outside in safety, but he shuffled to access the crates. San's moan was a whimper when he was mushed into the wall, erection getting trapped between them painfully.

"Glad to know your rotten dick works just fine," Wooyoung uttered as he reached for the first crate.

Instead of helping, San lifted a trembling hand to his shoulder.

"Wait, please," he heaved. "I can't go out like this. I can't concentrate on fighting right now."

"You wanna wait until you calm down?! Think of some happy thoughts?! In their lair?! And don't tell me you can actually will this down while still pressed against me." To prove his point, Wooyoung cocked his hip in San's direction, mushing into the hard flesh under his pants. Though he gulped, icy satisfaction filled his chest at San's protesting shriek.

San struggled for words, maybe even for thought. When he came up with a genius idea, Wooyoung was about to launch himself into the cave to get ripped apart by the fouls.

"Let me take care of it. I'll make it quick," San gritted. Shame laced his voice, but his hand didn't hesitate to put his gun into its holster and fall to his crotch. Wooyoung brought as much distance between them as possible, which was still close enough to feel his movements. He made a face.

"Really? While they are a tunnel over?" He grimaced at the thought of the fouls, but San determinedly fiddled with his drawstrings.

"Just listen away for a second," he muttered, distracted. Something heavy hit Wooyoung and he stiffened, terrified of the swoop in his belly when he felt San's hand move along the length of him.

It was good that it was dark because otherwise, Wooyoung's depraved head might have risked a peek.

He gulped, staring straight ahead. The situation both repulsed him and had heat swirling in his belly. San's grunts were low in his throat and Wooyoung felt every motion as he tried to make it quick. Somehow, his mouth never felt so dry. It was almost as if his karma came back to haunt him after his actions a few nights ago.

With this angle and their narrow space, San had no other choice but to jerk off on him. 

Wooyoung hid his glowing face behind his hair. His hands braced against the crates before him, leaning away. San's breathy moan rang in his ears.

Perhaps it was the adrenaline, perhaps it was his born stupidity. Either way, it was the heat in his abdomen talking when Wooyoung opened his mouth without thinking.

"You could... You could use my thighs," he offered, begrudged. When San stilled, shame rushed through Wooyoung like a breath of fire. "Since I was at fault... For you getting hard, I mean. I also want to get out of here, so make it quick."

San exhaled. If he noticed how Wooyoung flinched when he grabbed his hips, he played it off. The hard flesh bumping against Wooyoung's backside was much more distracting.

"Imagine your boyfriend," San offered in return. He hastened to undo Wooyoung's pants, shimmying them down in their confined space.

Wooyoung tried to comply and failed gloriously. Yunho would never yank down his pants like this, would never nudge the head of his cock into Wooyoung's lean thighs that way. He would never because he had never.

Biting his lips, Wooyoung braced himself against the crates. Suddenly, they were his sole anchor to hold on to as San manhandled him as he pleased. He kicked Wooyoung's legs together and shoved him to bend over until he was presented so lewdly. Wooyoung made a face when he spat into his hand, but he supposed it was generous when that palm smoothed over the impolite hardness that kept knocking into Wooyoung.

Regrettably, Wooyoung's noise when San shoved into the hot space between his thighs was loud enough to be telling. He buried his teeth in his arm, drowning out San's snicker.

The hot, hard dick intruded between Wooyoung's thighs, shoving them open as if San were entering a person. The slide was slick with his spit, yet he smoothed a hand over Wooyoung's ass, gripping it in a firm palm to pull him open. Displayed like an item to use, Wooyoung hung his head. His shame hung in his ears and he stifled all noises. The pressure against his balls was all too delightful, and he noticed the heat wandering south, turning him treacherously hard. San grunted when he slammed his hips into Wooyoung's, producing a slapping noise that left a burning trail between his thighs.

Wooyoung gasped out, hoping the fouls stayed the fuck away from them. For being half rotten, San had a vigor that was scary in the best way, making Wooyoung tremble.

"You're too- Too rough, ah!" He whimpered, trying to regain some sanity for both of them. They were already in such a lewd position and San's bandages scratched over Wooyoung's skin. He couldn't feel any difference to San's skin down there, but his size was obscene enough to seem monstrous.

San thrust forth, dragging against Wooyoung as he buried in the meat of Wooyoung's legs.

"Was Yunho less rough with you? Do I not fit the example?" He panted, leaning over Wooyoung to whisper in his ear. Wooyoung whimpered at the angle. San was huge above him, bearing down on him with his crushing weight. If Wooyoung's mind wandered, it imagined being mounted by that big body, pressed flat to be no more but a hole for San to fuck into.

His body did something weird at that thought, ached inside as if there was an itch to scratch. Desperate for his sanity, Wooyoung shoved those thoughts away and remembered their situation.

"I- I wouldn't know," he whimpered, stifling another high-pitched moan in his forearm. He quivered under San, holding up against his weight as his body wanted to crumble.

It took San two more thrusts that were dumb with want until he understood why Wooyoung was so awful at keeping it together. Then his hot breath was back at Wooyoung's ear.

"Don't tell me... Your boyfriend never fucked you?"

Mortified, Wooyoung clutched to his crate. He leaked all over the ground and prayed San was close. Please let it be over soon.

It had to be the fungus spores in the air because Wooyoung's head spun with want.

"That's- That's none of your business!" Wooyoung shoved his hips back as if in retaliation and San groaned. His hands bruised Wooyoung's hips as they splayed him open for his hips to slam into. So close and yet so far.

San's breath grew ragged. Whether it was his newfound knowledge or his ridiculous high finally reaching his peak. He dragged against Wooyoung, stirring up the painful chaos between his thighs.

"So he didn't... Why not? How can he not want to mess you up?"

The insinuation that San wanted to mess him up was too much for Wooyoung. His knees buckled, but San was there to catch him, pressing him against the crates for his final thrusts. Neither of them had the brains left to think and Wooyoung reached down with one hand to help himself. He pinched his eyes shut and tried desperately to imagine Yunho but came up empty. It was San's voice that rumbled at his ear, his bandaged hand that held Wooyoung's waist, and his bumpy cock that rubbed against him.

Wooyoung came with a soundless cry. His spill splattered onto the crate before him and he jerked in San's hold. Before he could collapse, San's grip tightened when he followed behind. He made a hot, sticky mess, leaving it dripping down Wooyoung's legs.

Utterly disgusting, they stood to catch their breaths. Wooyoung's legs felt sore and his knees trembled, but San gathered his energy to remove himself. A sound of regret tumbled from him when he pulled back and tacky strings still connected him to Wooyoung.

Trying not to think about what he just did, Wooyoung cooled off his head on the crate. They could be thankful no fouls shuffled about.

A beat of silence as San sorted himself. Wooyoung didn't mind his state. Not as if San had anything more to expose. The shame burned like a beacon in his cheeks.

Wooyoung only startled when something wet touched his thighs. It swiped through the mess and he jerked around, about to tell San off.

He noticed it was a wipe. One of the rare wet ones that always made washing up so much more pleasant than if they were dry and sandy. Gulping down his protest, Wooyoung supported himself on San's shoulder as he tried his best to clean him in the dark. Soon, he couldn't find any more stickiness and Wooyoung took the wipe from him to clean his part. San winced.

"S-sorry. Since I took your first..."

The reminder made it even worse.

"Don't think too highly of yourself!" Wooyoung threw the wipe on the ground, leaving it to vanish as evidence.

"Nothing happened here today. Neither of us saw anything," he hissed at San when he jerked up his pants. The fabric rubbed his tender thighs, an incriminating reminder.

"Got it," San muttered. He didn't ask about Yunho again, mindful of the information he drew from Wooyoung so involuntarily.

Suddenly skittish, they spent another beat catching their breaths. Then, just when Wooyoung turned to get the crates and flee, San muttered again. His soft voice was the opposite of his rough thrusts earlier.

"Thank you, Death. I mean it."

Wooyoung sighed. One of these days, his minor acts of kindness would kill him.

"Wooyoung," he gritted as he packed the first crate. San's clothes rustled when he turned to face him.

"My name is Wooyoung."

They were too close to call each other false names. Though Wooyoung swore this was a onetime deal. They could go back to quarreling right away.

He heard the smile in San's voice, and it wasn't devious. Rather, it was light and happy.

"Nice to meet you, Wooyoung."

He went to work to help with the crates and crept in front of Wooyoung on their way back out. No fouls crossed their way and Mingi understood when they told him they got cornered.

With new loot and not daring to look at each other, they made their way back to the shelter.
