Ren. 

Yusuke

May I require a little bit of your aid?

Yusuke

I’m waiting at LeBlanc. 

This isn’t something that is usual between both of them. Nothing prepared him for these three new messages logged into his chat. Just to be sure, Ren checked the day displayed on his screen. This wasn’t Thursday. Between the two of them, there’s this silent agreement that Thursdays are their chosen day. Yusuke, specifically searched for him on any other day but Thursday—raised some alarms in him, truthfully. Not to mention, Yusuke just revealed to him about his second gender not too long ago. And it hasn’t been long enough for him, Ren hasn’t even finished the book that talked in depth about Omegas. It was all still overwhelming to tackle, but Ren would rather struggle carrying the pressure than leaving Yusuke alone.

“Who’s that?” Morgana peeked his head close, “What, Yusuke?! What’s up with him?” 

“That’s what I’d like to know too…” The message was sent fifteen minutes ago. Ren didn’t check his phone on the train, so it was left ignored until he finally arrived at the familiar backstreets of Yongen-Jaya. 

Ren

Hey! Sorry. Just got off the train

Ren

Heading to leblanc rn. Is something wrong? 

“Ren, I think it has something to do with this omega pheromone stuff.” The tip of Morgana’s nose twitched, now most of his body was craned outwards; cat paws grasped at his shoulders. Ren walked faster to LeBlanc as his cat companion talked. “I keep smelling Yusuke! It lingers in the air, you know. Like a trail? It’s as if he’s trying to guide you—an alpha—to him. Blech. The scent is really too strong.”

“Yeah?” For Ren, the scent, the pheromone that trails in the air sat on top of his senses pleasantly. The faint taste of sweet settled at the back of his throat, a fresh citrus with a playful tang of something sultry. However, the more Ren got closer to LeBlanc, the freshness dissipated. Leaving only a pungent, sickeningly sweet scent of a certain someone’s pheromone. Morgana gagged beside him, then leaped off his bag with ease. “I’m outta here! Going on patrol!” And so he went. To the streets of Yongen-Jaya. 

Ren stared at the door of LeBlanc, the plaque still turned to ‘open’. However, peering inside through the glass, Ren didn’t find any regulars he expected to see. The cafe seemed to have been steered clear of people, and it stuck out to him. When he opened the door, Sojiro still greeted him like always. “Yusuke’s upstairs.” He said, inhaling the last bits of his cig. “Been waiting for you for a good hour. Go check him out.”

“Oh… Sure, yeah. I got his message.” An hour? He thought Yusuke had just been here for no more than twenty minutes. “Oh, um. Sorry, Sojiro-san, but I think it’s something serious. Could you perhaps…”

“Stay away from upstairs?” His eyes glinted in a peculiar light.

“Well, yeah. Something like that. Sorry. It's hard to get privacy when I have no door.”

Sojiro laughed, he pulled out another cig; and lit it up with a quick, swift motion. “Yeah, yeah, I won’t go upstairs or whatever. You don’t need to worry about me going up.”

“Appreciate it, truly.” Ren bowed his head slightly, before taking himself to the stairs leading him to Yusuke. LeBlanc smelled like him. Like citrus and paint. Even when Sojiro-san was smoking, Ren could only smell Yusuke. In this world, where there’s supposedly various catalogues of scent logged in his nose, they seem to have been replaced with notes of Yusuke and Yusuke’s scent only. As Ren climbed up the stairs, the sight of their newest phantom thief came to view. 

Yusuke is sitting at the edge of his bed. His hand grasping the sheet beneath him, eyes locked into it as if entranced. His cheeks were red, the same red of the lobsters he loved very much. The red, ran from his cheeks to his neck, which Ren barely could see; fortunately he caught a peek of it. Although Yusuke is looking like a piece of art now, his breath is irregular, there are short stops that show his difficulty in breathing. The scent radiating from him is pungent, it crashed into Ren’s senses like a truck; left him in a daze that roused something in him. 

Yusuke is… Yusuke is in heat. And it doesn’t look like he knew about it. 

“Ren.” He lifted his head up, those eyes that were unfocused just a moment ago—locked tightly into Ren’s. His eyelashes fluttered, there’s some kind of gloss enveloped Yusuke’s pretty green hued grey eyes; together with the glint that nestled in there, all of Yusuke felt like a lethal seduction. Ren gulped something down his throat. He approached his friend slowly, as if each of his feet were chained like whenever he met Igor and the twins. 

“Yusuke… Are you in heat?” The thumping of his heart was so loud he couldn’t even hear his own words. Standing right in front of Yusuke made his heart race like crazy, and it’s a miracle that his blood vessels were still intact; not exploding from all the force he’s internalizing. Yusuke tilted his head, which allowed Ren to see more of his neck. Why did Yusuke wear this shirt, the v-line shirt that exposes too much of his collarbone and neck? It wasn't his intention to bare his neck towards him, Yusuke hardly knew anything. However… It was primal in him to want an omega as wonderful as Yusuke. 

The artist shook his head, “I-I don’t know…” He pressed his legs together. “I feel hot, yes. And wet. I keep sniffing the lingering scent of you, it’s the only thing that made me less insane…” A sharp intake of breath. Yusuke is shaking. “Yet at the same time, inhaling your scent made me even more insane as well… How peculiar, I don’t know how to deal with this…”

“You’re in heat.” 

It wasn’t a question. Ren sliced through Yusuke’s confusion with a clean cut realization; one that anyone else could also reach with ease if they have their second gender awakened and in thirty feet of him. It wasn’t something so breakthrough, or something hidden so deep in layers he had to dig himself out. No, Ren knew Yusuke was in heat because his pheromones were going wild in this room. It sticks to everything, seeping into the cracks of his attic’s woods and clings to the sheet of his bed. Everything in his room has been drowned with Yusuke’s scent. But most importantly, is how Yusuke’s heat begs for the alpha instinct within him. 

Ren locked himself to his position. Gripping his own fists tightly. Yusuke is this unguarded because other than Phantom Thieves, he only had him. The trust that Yusuke placed on him is something sacred which Ren wanted to protect—just because he’s an alpha and knew slightly more than him … He shouldn’t take advantage of this. “I’m … In heat?” Yusuke fired back, eyes widened and blush adorned his fair cheeks beautifully. Ren bit his lip, pushing back his fangs from showing. “Yes. You are. You feel hot and wet. I can smell your pheromone begging me to do something with it … The wet — it’s probably — uh, your slick.” 

The shock within Yusuke’s face passed into something else; a realization that cleared some of the fog in his eyes. Ren gulped some of his saliva down, he shifted his weight from one leg to another, his fingers played with the longer part of his bangs. He couldn’t keep himself calm. Ren didn’t want to look, but his eyes couldn’t stop wandering to the wet stain on Yusuke’s crotch. The smell is too tempting. His throat is dry and he’s craving even just a drop of Yusuke’s slick.

Ren tried to compose himself. But his common sense is slipping from his grasp the longer he’s here. “You should get a suppressant—” Ren tried once more, clinging desperately to the rational part of his alpha brain. However, Yusuke grabbed for his hands; holding him with a desperation that squeezed his heart tightly. Ren gasped, he had avoided looking at Yusuke up until now. Finally forced to look at the artist, he was stunned by how … dangerously delicious his friend is. Yusuke’s breath is heavy, there are short stops between his breaths that sometimes sounded like a whimper. Ren wished he could sink his fangs on his slender nape. So he might draw out more of his whimpers. His moans. His cries. 

Yusuke brought his hand to his cheek. There was a combination of warm cheek and cold sweat that startled Ren. Yusuke didn’t realize this, nor had the ability to realize, so he just rubbed into his palm as if it was the only thing that could calm him down. “It hurts, Ren,” He whined. A low whine that sent waves of painful throb to him. His brain pounded, with both lust and fear. For the first time in his life, Ren Amamiya is scared of what he might be able to do. “I don’t think a suppressant can relieve me of this plight…” 

He knew. Ren knew it was too late for a suppressant. And this is most likely to be Yusuke’s first heat. There’s no way he could slap a suppressant as a solution and call it a day. Ren gulped something down again, his throat is dry and thirst coiled around it like serpents. His fangs grazed over his lips, unable to hold back anymore. 

“I can help,” He said, through gritted teeth. His limp hand now tensed to hold Yusuke’s cheeks. Ren tried so hard to not crush the omega with his touch. “But I have to touch you.” 

Yusuke looked at him through his eyelashes. For a few seconds, silence dragged on. Ren watched as Yusuke’s eyelashes fluttered, his grey eyes staring at him. “I-I need that desperately.” A trembling plea. Yusuke’s grasp on him tightened, “I need your touch, Ren… I don’t know how, but I feel like I will go mad if you don’t touch me…” 

Ren Amamiya let go of his restraint. He pushed himself closer to Yusuke, his hand toying at the artist’s lower lip. He lingered near his face, mouth twitching to kiss the other’s lips. However, there’s part of himself that is still sane. Pulling him back from stealing Yusuke’s precious first kiss, and instead, buried himself in the crook of Yusuke’s neck. It was fragrant with the sweet smell of citrus. The scent overwhelmed his senses, but also fueled the lust that has been simmering at the pit of his stomach. Ren kissed Yusuke’s neck, his cold lips almost sizzled when it met Yusuke's hot skin. The artist let out a sound; a moan that made Ren’s hair stood high. Possessed with something stronger than lust, Ren sucked Yusuke’s warm skin. Laying down hungry kisses and licks that left red marks all over the place. 

Yusuke moaned again, now mixed with whimpers that were so close to a song in Ren’s ears. “R-Ren.” Between his undecipherable moans, Yusuke called out to him. His fingers trembled, grasping on Ren’s shoulder like it was his only lifeline. Ren doesn’t really know what Yusuke is trying to say. His mind is far from clear. For the first time in his life, Ren followed what his alpha instinct is trying to tell him. 

This is not enough. So Ren lowered himself, lips tracing the bone of Yusuke's neck to his collarbone. Kissing him until there’s only red blooming on his skin. Even after countless marks placed on Yusuke’s fair skin, it still wasn’t enough. Ren could feel it in the scent that Yusuke radiated; a sweet seduction towards his senses. And Ren Amamiya is a simple man at his core.

He sank his fangs. The sharp tip of his teeth tore Yusuke’s skin, drawing out blood that tasted sweet in his tongue. Ren kissed the wound. Finding himself couldn’t live without a drop of Yusuke’s blood. It felt strange, but perhaps that’s just how heats are. 

“R-Ren…” Yusuke has his fingers grasping his hair tight. “I’m so lightheaded. I’m s-so.. so wet—”

“I need you—”

Yusuke let Ren push him to the bed. Entirely trusting his body to him. There was a gasp coming from him, a surprise that’s impossible to hide, but Yusuke submitted himself to him. Following his every word. Gesture. And Ren would be lying he didn’t find that wonderful. “I know,” he said. With a grunt gouged from the depth of his throat after that. Ren couldn’t help from grinding his bulge to Yusuke’s groin. His groin is so wet with slick he could even see the outline of his cunt. 

A wave of dizziness hits Ren for each grind he did, and it seemed it hit Yusuke too. “I’m .. I’m not going to …” He tried to get out the words, but he’s more focused on undoing his belt; which posed quite a challenge for his lust-addled brain. “I’m not going to actually penetrate you, because…” After a few seconds of battling his pants, his erection was set free. It slapped Yusuke's clothed cunt lightly, which earned him a soft whine from below. 

“Because I just can’t…” There is no aim in his words, Yusuke doesn’t look like he’s listening to everything, or comprehending every single word that he uttered anyway. Ren held both of Yusuke’s thighs, pressing them close to each other but still leaving enough space for his cock to be squeezed in between. Yusuke is looking at him with marvel in his eyes, stomach exposed, and legs lifted. Even like this, Yusuke carried an innocence so temptingly wonderful for him to ruin. Ren Amamiya took the pleasure to ruin it, suppressing his guilt with a desire too heavy for him to ignore.

Ren slid his cock between Yusuke’s thighs. The artist’s whole body tensed in response. If Ren still has remains of his common sense, he would be worried, but all of them have been discarded the moment his cock met Yusuke’s soft thighs. It might not be what he had imagined, but the tightness that squeezed his cock, the warmth that enveloped him… When Ren closed his eyes, he could even feel the outline of Yusuke’s wet cunt. 

Gritting his teeth, Ren snapped into the little hole he made, rutting into Yusuke’s thighs that were too skinny to be unnoticed. Ren clutched Yusuke’s thighs harder, and moans could be heard from below once more. He grunted in response, hips thrusting into this tiny hole as if possessed. Running towards the climax, without thinking much about anything.

“R-Ren…!” Yusuke called, his arms reached out to grab something of his. “Yusuke,” He called back, hips shaking uncontrollably. “I’m coming—”

His ejaculation cut short his words. The cum was shot towards Yusuke, but mostly landed on his stomach. Some reached its way to his jaw, however. Which made Ren’s cock twitch once more. It’s a good thing that his common sense is slipping back to him. 

“Uh.” Now it’s awkward. Yet his artist friend just let that happen; chest rising and falling trying to steady his breaths. “I’m sorry I dirtied your uniform…”

Yusuke didn’t seem like he cares that much about it.
