Genma looks at his watch, tapping his fingers on his desk. His Calculus III class was almost three hours long, and he’s still got another 30 minutes left.

His professor is starting to sound muffled at this point in the lecture, so Genma finishes up taking notes from the PowerPoint slide.

He sighs softly to himself, slightly irritated. It’s not that he struggles in the class. In fact, he doesn’t struggle in any class at all, really. But this is the class he shares with one of the smartest kids in his entire program, besides himself.

Raido Namiashi.

Genma turns his head to the left where Raido is sitting. He’s listening attentively, his notebook is covered in notes, and he’s got everything neatly placed on his desk.

Meanwhile, Genma has papers scattered all over the place, writing his notes on the back of his old assignment papers. He never really needed to stay organized to be a genius.

Raido suddenly notices Genma’s staring, looking back at him with a blank expression. Genma immediately looks away.

Truth is, Raido’s intelligence intrigues Genma. So the fact that he’s never gone out of his way to talk to Genma irritated him quite a bit, though he’d never show it.

Genma shivers at the thought. Thankfully, his best friend Kotetsu is throwing a party tonight where he can forget all about Raido, and hopefully get laid.

If there was one struggle that Genma has never known in his entire life, it’s how to get some. A little this, a little that, he doesn’t discriminate. 

He grins to himself, thinking about how hard they’re gonna go tonight, between him, Kotetsu, and probably Izumo, Kotetsu’s roommate and boyfriend from high school. They really followed each other to college… and it made Genma want to vomit out hearts from his gut.

Genma wasn’t really interested in settling down, not until he found the right person anyway, which he didn’t think would be anytime soon. He’s a picky guy when it comes to actual romance. Holding hands, kissing cheeks, less than a handful of people have ever seen that side of him in his few attempts at dating. For the most part it wasn’t really his thing.

For now, it’s sex and alcohol for Genma. He’s ready to get lit!

~

That night, Genma’s just about to leave his dorm suite when his roommate, Hayate, a sophomore, comes out of his room. 

“Going to a party?” He asks, walking to the mini fridge in his PJs. 

Genma raises his eyebrows at his attire, shaking his head in amusement. “Yeah, and no, you can’t tag along. There’s gonna be alcohol and you’re only 20.”

Hayate rolls his eyes. “I wasn’t gonna ask.”

Genma knew that, of course, but he almost wished Hayate would ask. Hayate didn’t really go out much. Genma knows he has really bad asthma, but he also has really bad social anxiety, and Genma wanted to help with that.

“Aren’t there any sophomore parties for you to go to? I’d ditch Kotetsu’s and go with you if you want, It’s a Friday night!”

Hayate looks at Genma at the doorway to his room. “Stay safe tonight, Genma,” he says with a comfortable smile on his face, obviously not going anywhere with that stack of snacks in his hands.

Genma just sighs and nods his head before Hayate disappears behind his door, shutting it.

When Genma arrives to Kotetsu’s and Izumo’s off-campus student living apartment, he parks at their building and gets out of his car, wearing a pair of athletic shorts and a tight T-shirt. Nothing fancy. He didn’t need it.

When he gets out of his car, he locks it with his keys and begins walking up to his friends’ building. He immediately notices the looks he’s already getting from other people walking from their cars to the party. He smiles at them, giving them all friendly nods as he continues walking, hands in his pockets.

When he gets to the door on the first floor, it’s already open with Kotetsu greeting people coming in. Then Kotetsu’s eyes meet Genma’s and they light up with excitement. 

“Zumo!!! Genma’s here!!!!” Kotetsu calls out, looking back into the apartment at Izumo, and then Izumo’s head pops out.

“Well, come on, don't just stand there! Get in here!”

Genma walks inside and the whole place already smells like alcohol and sweat. It was a typical college party, with so many people everywhere you look.

Kotetsu throws his arm around Genma’s shoulder and shakes him heartily, “So glad you made it, you won’t believe who showed up.” Kotetsu points over at a familiar blonde haired man who Genma had hooked up with before at a party like this. He looks back at Kotetsu and shrugs. “I’m looking for something… different.” Kotetsu raises his eyebrows. "What kinda different? Titties?" He says in almost horror. Genma just shrugs. "Maybe, who knows."

Genma walks over to the kitchen, leaving Kotetsu to continue mingling on with his guests, and immediately makes himself a whiskey and coke.

“I love those shorts,” a girl says to him, who was definitely giving Genma the eyes when she wasn’t staring at his ass. Genma takes a sip of his drink, winking at her. She starts playing with her hair, looking all excited. He scans her appearance, and she isn’t ugly, she just doesn’t seem to be his type. 

After a few more drinks he decides to leave the kitchen, feeling pretty good as he walks over to the living room, finding a seat on the couch. The girl followed him and immediately sat down on his lap, and all of her friends followed, sitting down all around them. Genma sighs, defeated. 

His eyes scan the room. Everything is so loud, between the music blasting and the amount of people talking. There were a few people here that he knew from his classes, but for the most part, everyone here was a stranger. He also didn’t major in the arts like Kotetsu, and this was his party more than anyone’s.

That’s why Genma almost froze when he saw Raido Namiashi walking into the living room.

What the hell…

Raido?! 

They make eye contact, and Raido gives him a look that Genma can't quite figure out. Then he walks into the kitchen, disappearing.

This is not happening.

Genma taps on the girl’s shoulder, the one who was sitting in his lap, telling her to move. She does, and he gets up, heading straight to the kitchen.

Genma’s eyes meet Raido’s as soon as he walks in. They’ve never actually spoken a word to each other outside of school. They’ve only ever really interacted in front of the class when they were both answering questions together.

“Hey,” Raido says confidently, raising an eyebrow, probably wondering why Genma had such a hostile look on his face.

Genma relaxes the muscles in face, trying to look more friendly. He definitely wasn’t here to start anything, only investigate.

“Hey, Raido, right?”

Well, fuck. Of course you know his name, stupid.

Raido chortles, his lips forming into a slight grin as his eyes scan Genma from head to toe. “Yeah… Genma, right?”

That confidence in his tone… usually, Genma found it to be annoying, absolutely repulsive coming from Raido, but tonight, he realized he also found it to be… hot.

He sees that Raido hasn’t made himself a drink yet and takes the opportunity.

“Can I make you a drink?” Genma says confidently, walking over to the liquor and grabbing a cup. “What’s your poison?”

Raido takes a second to think about it. “Vodka soda,” he responds, “with lime.”

That’s… adorable.

Genma makes him a vodka soda with lime, then hands it to him as he takes Raido's free hand, leading them to a quiet place for them to just talk.

Raido doesn’t oppose.

They end up in the bathroom, which, with any luck for Genma, will go exactly as it sounds.

“So, tell me about yourself. How do you know Kotetsu?” Genma asks, leaning against the bathroom counter.

Raido takes a sip from his drink, staring into Genma's eyes. “We met in music theory 2 years ago, before I switched majors.”

Genma nods his head, following. “What’s your major?”

“Computer science,” Raido responds, putting down his drink. “yours?”

“Same… but I plan on getting my MD.”

"Same," Raido responds, closing the distance between them.

He lifts his hand to touch Genma’s hair, who… doesn’t object.

Genma’s mouth is parted open at this point, a little bit surprised, but completely turned on.

Oh fuck.

He’s blushing.

Raido raises his eyebrows, definitely noticing Genma’s flustered face.

“Do you like it?” Genma almost growls, and he can’t take back the words once they leave his mouth.

Raido takes another sip of his drink, never breaking eye contact, then sets the cup back on the bathroom counter. He leans in close to Genma's ear. "I do, and I can't stop thinking about pulling it," He responds in almost a whisper.

Genma blinks, his mouth still parted open, and his eyes drift to Raido's lips. "Do it."

Raido doesn’t waste any time. He grabs a wad of Genma’s hair from the back of his head, pulling it gently, making Genma’s head lean back. Then his lips are on Genma's neck, leaving a trail of kissses down to his collarbone.

Genma was not expecting this, but he’s not complaining about it either. He closes his eyes, a groan slipping from his lips, and Raido has to shush him. He sticks his finger over Genma’s lips to keep him quiet, but Genma only takes it into his mouth, sucking with intent.

Raido shakes his head, swearing under his breath and then adding another finger. He watches this for a while, then he continues where he left off, licking and sucking Genma’s neck, kissing up to his jawline, with his other hand gripped deep enough into Genma's thigh to leave a mark.

Suddenly, someone knocks on the door, and the two of them immediately let go of each other and stop what they’re doing.

“Genmaaaaa! Come back!!!!” It’s the sound of a female voice, the same one from before.

Genma rolls his eyes to the back of his head, he can’t escape this chick tonight apparently. “I don’t know her.”

Raido had Genma pushed into the bathroom counter, almost sitting on it, so he gets up and brushes his clothes off to unwrinkle them.

Genma looks up at him, who looks away, slightly annoyed.

“You wanna finish this later?” Genma whispers to the short haired brunette, but he didn’t even seem interested anymore.

“I’ll see you out there,” he says before opening the door and leaving Genma in there by himself.

Genma stays in the bathroom for another few minutes, rinsing off his face. The nerve of that guy… wasn’t it obvious I wasn’t into her?

When he gets back to the living room, he finds his seat being reserved by the girl, who he should probably get her name by now. 

He goes to sit down, and the girl gets excited again. “Genma, you’re back!” She exclaims, hopping right back onto his lap, and he grunts in agony.

“Uh, yeah. What’s your name, by the way?”

She turns around at him, smiling brightly before answering, “My name is Sarah, with a h, but don’t get me confused with Sara with no h, or Sahra with a h in the middle but no h at the end. Finally, I thought you’d never ask!”

Genma blinks.

What?

“Well, it's nice to meet you, then, Sarah… with a h…”

She nods her head, silently clapping her hands with excitement.

Oh boy.

After another 15 minutes or so, Genma’s eyes scan the room to find any method of escape, then he spots Raido standing in the corner finishing his drink, watching him.

Genma narrows his eyes.

How long has he been there?

Raido takes the last sip of his drink, never breaking eye contact, then tosses his cup in the trash and starts heading to the front door.

Is he leaving??

“Uh, Sarah, I’ve gotta get up,” he says urgently to the girl sitting in his lap, rambling on about nail stuff.

“And I told the lady, I don’t ever want to see your face again, you RUINED my cuticles!!”

“Uh-huh. Please get up.”

She finally does, and Genma hops to his feet, trying to catch Raido before he’s gone.

He opens the door to the group of people smoking cigarettes outside talking, his eyes darting in every direction looking for Raido.

He finally sees the man in the distance, walking to his 2003 Toyota Corolla.

Genma shakes his head, then sprints after him as fast as he can, “Raido! Wait!”

Raido stops to turn around, and Genma stops running as he approaches him. “You’re leaving?”

Raido looks around at the people walking to their cars. “Yeah, it’s about that time.”

Genma just stares at him in disappointment. “Yeah, but, it’s still early, don’t be a party pooper…”

Raido chuckles, looking at the ground. “I don’t stay at these things for too long.”

Genma nods his head, slowly. “What if I told you I wanted to go home with you?”

Raido rolls his eyes. “Don’t you have people to entertain?”

Now it’s Genma’s turn to roll his eyes. “I swear she just kept following me! And her whole entourage!”

Raido looks back at him, narrowing his eyes in contemplation. “Did you have a lot to drink?”

Genma shrugs. “I’m not a lightweight, Raido, three drinks is a buzz to me.”

Raido raises an eyebrow. “Yeah? Well then I guess I’d tell you that you have to get to know me first,” he says sarcastically, chuckling

Genma crosses his arms, smirking. “I’ve actually wanted to get to know you for a long time now, since you started showing up in my classes. But you’ve been too proud to talk to me.”

Raido smiles a little, but immediately tries to hide it, and Genma finds it insanely adorable.

“Not proud, you’re just intimidating. And sexy.”

Genma feels a little more fluttery than he’s used to at the compliment, and his feet begin dragging him closer to the other.

Have we really not talked to each other until now for the same damn reason?

When he’s close enough to the man in front of him, he stops, and plants a kiss on Raido’s lips.

He tastes like a combination of breathmints and vodka, pretty much what Genma was expecting, but he was not expecting Raido to be this good of a kisser. “You, uh… forgot to do that earlier,” Genma whispers, detaching himself from the other before he could get too excited, and Raido gives him a lustful grin. “I didn’t forget…”

Genma raises his eyebrows. “So… you did plan on finishing what we started,” he whispers again with confidence, coming in close to Raido’s ear and grabbing him by the waist. Raido shakes his head, clearly amused, but still showing the utmost restraint. “Easy there, tiger… let’s go back to my place first,” he leans in to whisper in Genma’s ear, “I’ve already called a cab to take us there, I just needed to lock my car.”

Genma’s eyes go wide, thinking about his own car. “Mine is already locked, I’m sure they’ll be fine here overnight since we parked in the visitor lot.”

Raido nods his head in agreement.

Suddenly, the cops start rolling up one car at a time, followed by Raido’s cab.

”Fuck!!! Kotetsu!!”

Kotetsu had it under control though, he knew the neighbors had called the cops to complain about the noise, so he told everyone without their IDs to beat it. That’s why so many people were leaving just now. Kotetsu greeted the cops and welcomed them in, giving Genma a wink.

Genma sighs, feeling bad for leaving his best friend, but Kotetsu’s wink from the doorway lets him know he and Izumo have it under control. They know how to work cops better than anyone.

”Let’s get out of here,” Raido finally says to Genma, and they both head for the cab.

~

When they get back to Raido’s place, Raido leads them in, sneaking past his roommate, Aoba’s room, into Raido’s mix of a nerdy comic book and sports themed room. 

“I don’t know much about this stuff, but Kotetsu reads a lot of comics-”

As soon he shuts the door, Raido, smiling, shoves Genma into his bed and shuts him up with his lips pressed on top of his. His body rolls against Genma’s as their shirts ride up, their hands searching desperately for something to grab onto. Genma’s hands are in Raido’s hair, while Raido’s are riding up Genma’s thighs, reaching underneath his shorts and underwear to grab his ass. Genma moans when Raido squeezes his buttocks, rolling the globes in the palms of his hands, their lips still moving against each other’s, tongues colliding.

Genma reaches up for Raido’s T-shirt, helping him take it off. Then Raido lifts Genma’s shirt, kissing and licking up his torso as he helps him drag it over his head. They resume kissing, with Raido straddling Genma on the bed, before Genma decides to switch their positions with his legs. “Can I top you?” He asks the short haired man, who folds his arms over his head with a smug look on his face.

He nods his head yes, scanning Genma’s body with his eyes, his expression being way more sexually explicit than earlier when he was checking him out at the party.

“The lube is in the top drawer with the condoms,” he shares, pointing to show Genma where it is, and Genma grabs a condom and the lube, then turns back to look at him.

Raido just watches him from below, biting his bottom lip, and Genma begins unbuttoning Raido’s pants and dragging them down. Genma’s mouth immediately starts watering over seeing Raido’s bulge, then he removes his own shorts and underwear, leaving him naked in Raido’s cool room. Raido shifts his body, lifting himself up on his elbows to get a good view, licking his lips. “Shit…”

Genma bites his bottom lip, his hands meeting the waistband of Raido’s underwear and slowly pulling them down, revealing his fully erect length. Genma gently moves his hand to Raido's hard member, making him moan for the first time in Genma’s ears. Genma spits on Raido’s cock, not wanting to use the lube for this, and begins jerking him lightly, building up a pace, listening to Raido's moans and mewls to guide his movements. Raido's face is red, his mouth parted open from making sounds of pleasure. Genma finally decides to remove his hand, replacing it with his mouth.

Raido throws his head back, moaning uncontrollably now as Genma goes down on him, hard. He has Raido’s cock all the way down his throat, using his tongue to stroke behind the tip. “I don’t wanna cum yet…” Raido murmurs, stopping him and bringing him back up on top of him, their lengths brushing against each other’s as their lips meet again. They grind their hips together lightly, with Genma’s cock getting stuck rubbing between Raido’s thighs, driving him absolutely mad.

He lifts Raido’s legs over his shoulders, reaching for the bottle of lube and the condom, ripping it out of its packaging with his teeth. He adjusts the condom around his cock, then pours some of the lube into his palm before putting it on the nightstand. He dips two fingers into the lube and reaches them between Raido’s cheeks, finding his rim and rubbing him all around, then opening him up with his fingers.

Raido cries out his name as he welcomes Genma's fingers, panting and moaning, hissing and groaning, squirming the deeper Genma’s fingers went. “Do you like that?” Genma whispers, knowing damn well that he does, but he just wants to hear him say it.

Raido nods his head yes, barely able to focus on speaking. For being one of the smartest people at the college, there was absolutely no blood left in his brain now. 

Genma chuckles lightly, rubbing the rest of the lube from his hand all over his dick. Then he lines himself up with Raido’s entrance, staring into his eyes. “You ready?”

Raido bites his lip, for the first time showing a shy expression, and he nods his head yes. Genma goes easy on him at first, sliding his way in slowly and carefully, letting Raido adjust to his size. Raido hisses, slamming his eyes shut as he grabs a handful of wadded up bedsheets on both sides of his body. Genma finally pushes himself all the way in, and they lock eyes, completely focused on one another. “You feel… so fucking good…” Genma purrs before another groan slips from his lips.

He begins fucking Raido slow, rocking his body with his legs strung over Genma’s shoulders, never breaking eye contact. Then he picks up the pace, his thrusts getting heavier, faster, deeper, until he had Raido whimpering underneath him with tears in his eyes. "Right there, Genma..." Raido murmurs, and Genma starts thrusting even faster.

He can't get over the way Raido is staring at him, calling out his name with all the pleasure he feels present in his face, it's all gonna send Genma over the edge. He's whimpering now himself, with every thrust of his hips, a new sound coming out of both of their mouths. He looks down, watching his cock stuff Raido's tight hole, disappearing and reappearing, stretching it out for him. "I’m gonna cum.." Raido grunts, and then the white fluid erupts from the tip of his cock, all over Genma's face.

"Fuck, I'm so sorry," Raido says, horrified, but a grin has already appeared on Genma's face as he bottoms out, rutting into him, chasing his own release until he finally fills his condom to the brim with his own white fluid. Genma licks his lips, tasting Raido all over his mouth. "Let me get you a towel," Raido says beneath him, so Genma pulls himself out of the other. Raido smirks at Genma as he gets up, limping to the bathroom to get a wet towel. 

He comes back and Genma cleans himself up, as does Raido, but Genma notices Raido hasn't put his clothes back on. "What, you want another round?" Genma asks, smirking back at him. Raido just chuckles, laying beside him with his head in his hand. "Would you let me top you?" Raido asks, biting his lip gently.

Genma stares at him for a second, then leans in close to him, "In an instant."

Raido takes a handful of Genma's huge ass, squeezing it and jiggling it in his hand. "I bet you can guess what I want..."

Genma's face flushes a little bit, but he doesn’t really want this night with Raido to end yet. So he gets up on his hands and knees, with Raido immediately getting up to follow him, rubbing his hand down Genma's spine from behind him. He's hard again, and he takes his cock into his hand, brushing it between Genma's cheeks, making them both groan. Raido grabs the lube and a condom, putting on the condom and dumping a handful of lube into his palm, rubbing it all over his cock. Then he begins massaging Genma's ass, smacking it, not too hard, but hard enough to watch it jiggle.

“Ahhh..” Genma whimpers, burying his head into the pillow as Raido spreads his cheeks. He's licking his lips at the sight of Genma in this angle, rubbing his tip against his rim. “Gonna fuck you so good,” Raido growls, smacking his ass again before entering two lube-covered fingers to stretch him out. Genma squeezes the edge of the mattress, moaning as Raido’s fingers loosen him up. He continues this for several minutes, letting Genma open up, before finally removing his fingers and replacing them with the tip of his cock, his hands gripped into both sides of Genma's waist.

Genma's breath starts to quicken as Raido slowly begins to enter him, and it takes everything for Genma to keep himself from collapsing as Raido begins fucking him from behind. It feels good, so good, the way Raido's thick cock slides in and out of him with the help of the lube. Genma grabs onto the front of the bed, while Raido picks up the pace, sending mighty thrusts into Genma’s hips, jerking his waist back into his hips with every thrust. Raido cant stop staring at the way Genma’s ass looks taking his full length like this. He’s not gonna last long at all.

They continue this rhythm for another minute or two before Raido grabs Genma’s hair from behind him, pulling him up closer to Raido as he continues pounding into Genma’s ass. Genma can’t shut up, and it’s the sounds that were coming from his mouth that makes Raido finally bottom out, filling his condom, making Genma spill himself all over the bed sheets.

They're both out of breath, and Genma collapses beside the pool of white fluid beside him. "Sorry..." he mumbles to Raido, his face still buried in the pillow. Raido just chuckles, kissing the back of his head. 

Genma finally gets up out of the bed to let Raido change the sheets, and he throws the dirty ones in a separate bin from his clothes. Then he puts the new sheets on his bed, with Genma helping him, neither of them bothering to put on clothes. "We can't get these dirty, I only have two sets of bedsheets," Raido jokes, smiling at him, “so don't get any ideas." Genma shakes his head, smiling at the floor as his feet drags him over to the light switch. "Can I turn this off now? You tired me out..."

“Did I?” Raido responds sarcastically, making his way over to Genma and raising his hands to his waist, pulling him in. "I'll do it again in the morning..."

Genma pushes him away jokingly, flipping out the light and making his way back to the bed. "Don't tempt me..." he says with a grin on his face, getting underneath the bedsheets, staring back at Raido, who finally joins him under the covers.

"So, is this gonna mean nothing to you by the morning?," Raido says faintly, laying down and facing Genma. Genma is laying down and facing him, too. "Is this still about that girl? She was just a bimbo, I think. She liked my ass a lot." 

Raido can't help but chuckle at this. "Who doesn’t?” Then he looks away from Genma, slightly worried. “It’s not about her, I just don’t like being a one night stand.”

Genma thinks for a second about what to say next before finally speaking.

"Denny's in the morning?"

Raido closes his eyes, snorting. Then he opens them again and finds Genma’s, nodding his head yes in approval. “I'm always down for a Grand Slamwich."

Genma raises his eyebrows, smiling at him like an idiot. "I'll give you a Grand Slamwich."

Both of them laugh at Genma’s silliness, feeling comfortable in each other’s presence. Then Genma gives him a soft expression. "So tomorrow, we'll get breakfast at Denny's and just hang out. No obligations, just getting to know each other."

Raido agrees, nodding his head. "Deal." Then he yawns big and wide. "Goodnight, Shiranui," he says before turning to the other side, smirking.

Genma raises his head to look at him, "You remembered my last name from class!"

Raido continues grinning to himself, pretending to be already asleep. Genma lays back down, scoffing out loud, but still smirking.

Whatever, Genma thinks to himself, knowing he's not asleep. He decides to lay against Raido, their backs touching as they begin to drift off.

Genma doesn't know what's going to happen between him and Raido, but he can't remember a time when someone made him feel like this.

He knows one thing is for sure: they're gonna have an eventful day tomorrow.
