infected with his blood, weak in his hands

Summary:

“What are you trying to imply?” He raised an eyebrow, sitting up properly and turning to face him. Osomatsu laughs at nothing, proof that he truly was too drunk to think right now. He finally turned his head to look at him, eyes glancing in between his face and crotch with a hunger in his eyes. Ichimatsu swallowed thickly under his gaze. What the hell did he want?

“I’m just saying that, if you want, you can use your onii-chan as practice,” Osomatsu’s voice dripped with honey, his speech slurred in a way that made his words sweeter. “You’re gonna need help if you want to have good sex with a girl, right? Onii-chan can be your test girlfriend for tonight!”

Work Text:

Ichimatsu lied when he said he’s never kissed someone.

It wasn’t technically lying because, truth be told, he’s never kissed a girl so there was no reason for his brothers to be pissed at him. He still considers his first kiss to not be stolen. After all, the one he kissed was a boy. Not only that but he was his own brother.

He tried not to think about it too often. It was high school. They just did it to practice. It was different because they were so young. Millions of excuses echo in his head, bouncing off of each other until they were all he could think about. He knew he was depraved, disgusting, and absolute garbage but it’s different when you’re in high school. At least, that’s what he told himself.

Him and his brothers were scattered across their room, beer cans littered around with a heavy scent of smoke around them. Ichimatsu’s eyelids threatened to close, but he was determined to stay awake. His mind was whirring with thoughts of tan cat girls that if he couldn’t vent out his frustrations the proper way, he’d be sure he was going to wake up to a wet dream and dirty pants. He also thought about Osomatsu but that was mostly because the man was sitting next to him on the floor in front of the couch, the two of them being the last ones awake.

“Hey, Ichimatsu,” Osomatsu turned to look at him, his eyes half-lidded and slightly glazed over. “We haven’t done something like this since high school,”

“We didn’t drink in high school,” Ichimatsu would give him a glare but he was honestly too buzzed to even think about anything other than those tan catgirls. “You forgot to say reunion,”

There’s a pause from Osomatsu. A long one. It’s awkward. But the silence is broken up by his sudden laughing.

“Haha! I forgot,” Osomatsu looked back at the ceiling, the hedonistic benders of the past month finally catching up to him. Too bad it probably killed off whatever was left of his brain cells too.

The silence between them feels long. Ichimatsu was itching to make conversation but all he had on his mind were those damn catgirls. They teased him, begged him to fuck them with his dick, had an open mouth ready for sucking, and a pussy to be pounded into. Maybe they’d even take it up the ass for him.

“Do you remember when we kissed?” Osomatsu suddenly asked, eyes now on the dangling light switch. Ichimatsu’s eyes followed his brother’s, both of them now on light. He blinked slowly, trying his best to process his words.

“Yeah. I was pretty bad at kissing you,” He said, eyes now glancing around to see if any of his brothers would stir in their sleep. When they didn’t even move an inch, he let his eyes drift back to the light switch.

“You could always get better with practice,” His older brother said, quite unhelpfully at that. Ichimatsu scoffed.

“Kinda hard to do that when both of us don’t have a girlfriend,”

“Who said it had to be with a girl?” Osomatsu’s eyes look at him, not bothering to turn his head. His dumbass smirk was on his face like always. Ichimatsu felt something stir in him. Whether it was annoyance or something else, he didn’t bother to know. He just wanted to get off right now.

“What are you trying to imply?” He raised an eyebrow, sitting up properly and turning to face him. Osomatsu laughs at nothing, proof that he truly was too drunk to think right now. He finally turned his head to look at him, eyes glancing in between his face and crotch with a hunger in his eyes. Ichimatsu swallowed thickly under his gaze. What the hell did he want?

“I’m just saying that, if you want, you can use your onii-chan as practice,” Osomatsu’s voice dripped with honey, his speech slurred in a way that made his words sweeter. “You’re gonna need help if you want to have good sex with a girl, right? Onii-chan can be your test girlfriend for tonight!”

Ichimatsu blinked. Something in his heart ached. He didn’t understand Osomatsu’s feelings for him, let alone know if they even existed more than a familial bond, but in this moment he wanted to be tricked that the eldest cared more than he let on, even if he knew it was a lie in the end. What was he supposed to be feeling right now? Logically, probably disgusting. But the pit in his stomach was replaced with something else soon after. A heat that couldn’t be extinguished by his fantasies of tan catgirls. A carnal desire for his brother was ignited in him and he was going to make his onii-chan take responsibility. The duel wielding desires wasn’t helping the morally questionable Ichimatsu, who’s horniness and drunken state was making sure he wouldn’t be able to think clearly.

“Fine,” He grits out of his teeth, tearing his eyes away from his hungry eyed brother. Out of the corner of his eye, he saw Osomatsu smirk, then turn away and pump his fist. He acted like he scored big at pachinko, which was the complete opposite of how Ichimatsu was feeling right now. He quivered as he reached out his arms, averting his eyes as his brother slowly found his way in them, sitting in his lap.

“You’re such a bad nii-san,” Ichimatsu bit at him. Osomatsu could only smirk as he rose above him, cupping his face as their mouths moved closer together.

“Ichimacchan loves it though~,” Osomatsu finally closed the distance. Ichimatsu’s eyes forced closed, just letting his brother kiss him. His own arms holding his brother tight, as if he could escape at any second. He wanted to hold onto him. Even though his nails dug into Osomatsu’s hoodie as if he wanted to rip him apart, his mouth made different sounds. Ironic how the only way he can be honest with what he’s saying was when Osomatsu’s tongue was in his mouth. How funny that the moment where he was close to saying something, anything that bridged past what their relationship should’ve been, Ichimatsu couldn’t say a word.

Osomatsu’s legs wrap around his torso, now sinking down directly into his lap. He could feel that his brother already had a massive hard-on, possibly something he hid when he offered his body to Ichimatsu. Drool was seeping out of their mouth, another sign that both of them were still bad kissers, but Ichimatsu couldn’t help but revel in it. He was disgusting, absolutely so. But there was something in the disgust that he could get off to. Something that made him quake with his less than pure intentions.

His big brother eventually left for air. Osomatsu was smiling as he caressed Ichimatsu’s cheek. Something in him wanted to lean into the touch, but that would mean he’d have to admit to himself that he actually liked Osomatsu.

“Ichimatsu is so gross, isn’t he?” Osomatsu chuckled, “It’s okay. I’ll take responsibility,” Their lips meet again. Yet it was different this time. Osomatsu moved his hips a little, almost like he was trying to test something. Ichimatsu’s eyes widened at the sudden friction of his hips and he couldn’t bite back the moan he let into his mouth. Osomatsu smiled into the kiss, grinding into Ichimatsu’s sweatpants. The roughness of his clothes against his dick (that he couldn’t admit was hard) was almost too much. Being stimulated like this… it fed into his masochistic ways. No matter how much he wanted to deny it, his body always told the truth. And it said that he needed Osomatsu right now.

He growled, his sharp teeth now digging at the tip of Osomatsu’s lips. It was Osomatsu’s turn to be surprised. He tried to tug away but it only made Ichimatsu’s teeth dig in more. Ichimatsu bucked his hips upwards, making his older brother let out a groan of surprise, his own cock left unattended. Ichimatsu’s grip left the back of his hoodie and now rested on Osomatsu’s hips, using him as the friction he needed to try to finish himself. His teeth left his older brother’s lip, face now buried into his hoodie.

“A-ah! Ichimatsu! Too fast!” Osomatsu cried, trying to tug him off of himself. But Ichimatsu’s grip was too strong. As he gave into his desires, gave into what made him human trash, he thought of Osomatsu. He thought of Osomatsu and how stupid he was and how much he’d like to fuck the stupidity out of him. His cock throbbed, not caring what he did. He just wanted to get off.

It didn’t take him long to finish, his cock leaking out soon after. The moment he hit his orgasm, he bit down on Osomatsu’s chest, not sure if he hit skin or not. Both of them were trembling in each other’s grasp, their chests heaving at the animalistic humping Ichimatsu had displayed.

Ichimatsu raised his head from Osomatsu’s hoodie, immediately letting go. Osomatsu tugged himself out of Ichimatsu’s sticky lap, scowling a little.

“...seriously? These are my good jeans,” Osomatsu sighed, crossing his arms. He was quick to stand up to take them and his underwear off, his throbbing cock now out for display. Ichimatsu quickly looked around, eyes going from each brother. When he was sure that all of them were still asleep, his eyes went back to Osomatsu.

“Hey, Ichimatsu,” Osomatsu grinned, still standing. “It’s no fair you were the only one who had fun! Repay me for letting you use me,”

Ichimatsu sat there, thinking for a moment. I mean, it was only fair that he gave Osomatsu something in return too. Swallowing thickly, he propped himself on his knees, going over to where Osomatsu was and staring a little too hard at his cock. He had to shove down his pride for this but… whatever. Play stupid games, do a stupid blowjob. Even though he was already tired from cumming himself, he figured this was the only way he could pay off his happiness debt.

He enveloped the head with his mouth, careful not to use his teeth. How did people do this in pornos? The taste was awful. Too musky. Nevertheless, he proceeded, trying to remember what to do in all of his years of watching porn. He bobbed his head back and forth, trying to not clench his jaw and accidentally bite Osomatsu’s dick.

“Maaan~ You really suck at this, huh?” Osomatsu huffed, gripping the back of Ichimatsu’s head. “I mean, I dunno what I expected from a virgin. I guess onii-chan is gonna have to help you out!” In one swift motion, he shoved Ichimatsu’s mouth deeper onto his cock. It made the other man choke and gag. Tears pricked the corners of his eyes as he looked up at Osomatsu for some kind of mercy. But his older brother only gave him a toothy smile, eyes half-lidded and a shadow cast over him from the dangling light.

“Eat up!” Osomatsu said cheerfully before he pulled out, then shoved his cock back in Ichimatsu’s mouth. Each moment was torture as Osomatsu used his mouth however he liked, his throat threatening to spill bile along with the drool dripping onto the floor. But at the same time, Ichimatsu was meant to be used. He was meant to be discarded. He was meant to be a million things but Osomatsu’s was not one of them. Maybe they would keep this weird relationship, but it wouldn’t ever go anywhere. It’d just lead to Ichimatsu being used. And he was okay with that. As Osomatsu’s balls slapped his chin and his nose kept meeting his brother’s pelvis, he thought about dying. Just so Osomatsu could be his last.

Before he realized it, tears were running down his face as he struggled to properly breathe. He needed Osomatsu to finish quickly. Thinking on his feet, he raised his arm and once again gripped onto his brother’s hips, one of his hands traveling to Osomatsu’s ass and his finger teasing his hole.

He didn’t expect it to, but it worked. A salty and thick concoction was now down his throat and directly going into his stomach. Osomatsu groaned from being pleased from both ends, his hands trembling as he blew his load into Ichimatsu’s mouth. He finally let go of Ichimatsu’s head. His lips came off with a ‘pop’ and immediately he hacked and coughed. He had nothing to throw up, though. All he had tonight was beer, a few cigarettes, and now Osomatsu’s cum. All this coughing was going to be in vain, much like the orgasms the two experienced that night.

“Ah, you did so good, Ichimatsu!” Osomatsu came behind him and patted his head affectionately. Maybe it was his orgasm making him more stupid but this time he let himself enjoy the touch, even humming a little as his big brother showered him in praises that were sure to stick with him throughout the next day.

“It’s a bit too late to go to the bathhouse… Ah, whatever! I’ll put away our laundry and go to bed,” Osomatsu said, mostly talking to himself rather than to Ichimatsu. He pulled away his hand, making the younger’s eyes shoot up in surprise. When he was starting to turn around and leave, he grabbed his wrist, his heart hammering in his chest.

“Please… stay,” He muttered, looking away. Osomatsu’s eyebrows raised up, but the surprise didn’t stay. Soon a genuine smile came upon his face. Something that Ichimatsu wasn’t sure he’d ever see again.

“I’m right here, Ichimatsu. I’m not going anywhere,” Osomatsu’s voice was gentle. Reassuring even, as if he were luring in a stray kitten. Ichimatsu grumbled before taking off his own pants and underwear, laying on the floor as Osomatsu stroked his head. Ichimatsu wasn’t sure if he trusted that he wouldn’t leave, but he could sure try. As his breathing became softer and his chest didn’t seem so heavy anymore, he thought one last time about those catgirls but they ended up morphing into Osomatsu. He didn’t want to think about why.
