A Convincing Effort [NSFW] - Chapter 2 [Final]

[Chapter 1!]

“Look at that one,” Denki insisted, nodding toward a group of girls sitting across the room. “Is she new? She’s super hot.”

“We’re here to study,” Katsuki said flatly, throwing an eraser at his face. “Cut that shit out, you creepy pervert.”

“No, seriously!” he pushed. “Come on, just look.”

“She’s cute,”  Eijirou agreed, turning his gaze back to his textbook before Katsuki could glare at him. “Go say hi.”

“Study.”

“I can study later,” Denki grinned, leaning his head on his hand as he watched the girls giggle together. “Come on, what guy wouldn’t want a piece of that?”

“The Ace kind, for starters.”

“Shit. Right. Sorry.”

Katsuki rolled his eyes, still not bothering to look up, and Eijirou shot a little smirk Denki’s way, while he thought Katsuki couldn’t see it.

“You should have taken the chance yesterday, man,” Eijirou said gently. “It was all lined up for you and you just didn’t take the shot.”

“Honestly! He would have absolutely taken the bait, you practically laid down the challenge with I’m better than you at sex. It would have taken like two words to go all the way.”

“I don’t know what the fuck you’re talking about,” Katsuki insisted through gritted teeth. “Shut the hell up and do your damn homework.”

“You two would be great together,” Eijirou continued. “You understand each other so well, it’s super sweet, and you just know he would be super understanding when you don’t feel like doing The Sex.”

“Drop it.”

“Not until you admit it,” Denki grinned, leaning in against his shoulder. “Come on, Kacchaaaaaan, admit you looooove him.”

“Fuck off.”

“We all know,” Eijirou said quietly. “You don’t have to deny it. You’re allowed to have crushes! It doesn’t invalidate your sexuality!”

“You think I don’t know that?” he snorted. “If I had a crush on someone, it would affect my romantic title, it wouldn’t make me any less Ace. I was the one who taught you that. But I don’t have a crush on anyone, and if I did, it would not be on Deku.”

“Izuku,” Eijirou corrected him.

“Ugh. Yes. That. Shut up.”

“You’ve been trying so hard,” Eijirou smiled fondly. “Calling him by his name, all that extra training outside of class, I even saw you hanging out watching TV together the other day!”

“It was an All Might documentary,” Katsuki objected. “There’s only one TV in the dorms.”

“Still! You looked super comfy and happy together, sharing snacks and nerding out. It was really sweet. And especially now that he knows you’re Ace, there won’t be any expectations you’re not okay with, so it’s the perfect time to bring it up!”

“How many times do I have to say it?”

“Say it until you’re blue in the face,” Denki suggested. “We still won’t believe you, but at least you can say you tried.”

“I’m leaving, you fucks can do your homework alone.”

They both whined at him as he grabbed his books and stood up sharply, but they knew better than to try to stop him, just giving him pitiful looks as he stormed toward the doors.

“Excuse me?”

He froze, glancing back to see the random blonde girl Denki had been creeping on staring up at him, her eyes wide and far too blue. If she was there to complain at him about the idiots perving she was talking to the fuckin’ wrong man.

“What?” he grunted.

“Hi, my name is Michi! Um, I saw you from across the room, and I just wanted to... Say hi?”

“I’m not into humans.”

“You... Only like... Aliens...?”

“That is not what I meant,” he huffed, pinching at the bridge of his nose. “If you’re here to ask for my number or whatever, I’m not interested.”

“O-Oh.”

“You’re pretty or whatever, but I’m not... Into girls.”

He kind of hated himself for using that excuse, but it just seemed so much easier than giving the actual answer, dragging himself into a conversation far too long and charged for him to bother with on a whim.

“Oh! I’m sorry!” She took a step back, blushing. “I totally understand! Um, thanks anyway!”

She scuttled back to her friends, and Katsuki caught a glimpse of Eijirou and Denki at their table, laughing their asses off at his expense. He felt himself flush a little, flipping them off as he stormed out and grabbing his phone from his pocket.

“At least she asked me,” he typed out. “More than you losers can say.”

He tossed his books aside when he reached the dorms, too frustrated to deal with more homework, instead flopping down on the comfortable sofa and sparing a glance for Izuku’s wide-eyed stare from the other end.

“Gimme those,” he grumbled, snatching the bowl of chips from his lap. “What’re we watching?”

“Just the news,” Izuku answered, somehow not missing a beat. “They’re the fried chicken ones, want me to go grab the spicy chilli ones for you instead?”

“I can do it.”

“No, let me!” Izuku insisted, smiling brightly as he jumped to his feet. “I’ll be right back!”

Katsuki sighed, but he didn’t object, sinking into the cushions and kicking his feet up on the coffee table. Izuku was so much easier to hang out with than the idiots who followed him around all day, they just got each other in a way that no one else could. The perks of growing up together, he supposed; even if he’d been a dick half the time, they still understood each other.

“Here!” Izuku beamed, returning with a bowl of red-hot potato chips. “I brought you a drink too, it’s hot out there today. Gotta stay hydrated!”

“Thanks.”

“My pleasure!”

He sat down, a little closer to Katsuki than they’d started out, but Katsuki didn’t bother to question it. Izuku had always been like that, always wanted to be close to people, ready to nudge them, or poke them for attention, or even lean on them if he felt like being affectionate. It was nothing new for him to sit close enough to touch, their thighs pressed together lightly on the cushions.

“There were some cool fights today,” he said. “I was just watching coverage from Kamui Woods detaining a bunch of people from some attempted thefts. Some gang tried to run a bank heist or something.”

“Kamui is cool.”

“Yeah!”

They fell silent for a moment, watching the announcers drone on, then Izuku shuffled a little closer again, his cheeks tinged with pink as he leaned over. It wasn’t rare for Izuku to kick his feet up on the sofa and use Katsuki as a backrest, but it was a little less common for him to lean in shoulder to shoulder, side by side.

“What?” Katsuki asked pointedly. “Out with it.”

“W-With what, Kacchan?” he squeaked.

“You want something from me.”

“I don’t!”

“You’re sucking up to me, and getting all close and attentive and shit.”

“N-No! It’s nothing special!”

“Whatever, nerd.”

He went back to his bowl of chips, ignoring the twitching and mumbling beside him, until Izuku huffed a sigh that almost sounded exasperated. Katsuki sure as hell wasn’t gonna put up with that attitude.

“Just say it,” he demanded, elbowing Izuku in the ribs. “Seriously, you’re getting as bad as the assholes I just walked out on.”

Izuku pouted at that, and a small part of Katsuki felt a tiny bit guilty for it.

“I just, um... Was thinking. About... Last night.”

“You want to fuck?” Katsuki asked, snorting. “And you thought you could get that by what, bringing me chips?”

“I was trying to flirt,” Izuku mumbled, embarrassed. “I’m not very good at it.”

“Like I give a shit. You should know that isn’t how I work.”

“I do, I just...”

“Your idiot friends convinced you?”

“Maybe a little.”

“If you want sex you have to ask, I’m never gonna go ‘oh he’s hinting for sex’ or some shit.”

“But you’re Ace, I can’t just ask you outright if you want sex. You’ll tell me I’m an idiot!”

“First of all, sex is fine,” Katsuki said firmly. “I’m just not attracted to people sexually.”

“Is it bad if I admit I don’t know what that means?”

Katsuki paused, eyebrows knitting together, and Izuku burned bright red.

“It’s not,” he answered finally. “I just figured after all that dumb research you were doing before...”

“I mean, I know it, I just don’t... understand. I’m trying, really!”

“I know.”

“You do?”

“Mm, I can tell you’re making an effort, it’s fine.”

“Really? Thank you!”

Katsuki rolled his eyes, but he didn’t take it back, drumming his fingers on the arm of the couch as he contemplated.

“You know how sometimes you look at a person, and you think wow, they look good, but you don’t want to date them just because they look good?”

“Yeah, sure.”

“It’s kind of like that.”

“Oh,” Izuku screwed his face up, contemplating. “So you still think people are attractive?”

“Physically, sure. I can look at a dude and think yeah, he’s hot, but that doesn’t mean I want to drag them into bed like some assholes I could mention.”

“I don’t do that!”

“Haah? I didn’t mean you.”

“Oh. Phew! Okay then.”

“And uh... You know how sometimes you just feel like you need to jerk off, or whatever? Like there’s nothing mental going on, but physically?”

“Yeah! Dicks are weird.”

“I still get that. Hence... The other night.”

Izuku blushed again at the memory, and Katsuki looked away, a little warm himself.

“So it’s uh... Just a people thing?”

“I guess, yeah. It still... Feels good.”

“So um, if I asked you if you wanted to try it... You wouldn’t be like, bored?”

“Depends how much foreplay you expect from me.”

Izuku laughed, and Katsuki cracked a smile of his own – the way Izuku lit up, so unabashedly amused, was always a little entertaining to watch.

“What do you consider foreplay?” Izuku asked.

“Do you want to go up to my room and find out, or do you just want to sit on my face in the middle of the common room?”

“Uh. The first one.”

“Up you get, then.”

“Wait, but you’ve been eating spicy chips, will it...?”

“I guess we’ll find out,” Katsuki teased, slapping Izuku on the ass as he stood up. “Get your little virgin ass upstairs before I change my mind.”

“Oh! I mean, if you change your mind it’s fine! Just tell me, and we can-”

“Kidding, idiot. Go.”

“Going!”

He shoved the last handful of chips in his mouth just to make Izuku squirm, munching on them as they climbed the stairs to Katsuki’s dorm, and Izuku shivered when he heard the door lock behind them.

“Go wash your hands,” he instructed. “I’ll clear some space.”

Izuku nodded, jaw clenched tight, but Katsuki decided not to address it right away. He just left Izuku to go use his bathroom, taking the chance to turn down his blankets and grab a couple of old towels while he waited.

“Strip,” he directed, when Izuku returned. “Gonna wash mine too.”

“Wow, so sexy,” Izuku grumbled, pulling his shirt off all the same. “You really are bad at the foreplay.”

“Excuse me?” Katsuki narrowed his eyes. “I’m not bad at it, it’s just boring.”

“Okay, Kacchan.”

“I’m not falling for this shit.”

“Of course not, Kacchan.”

“Sit your ass down, nerd, I’m gonna blow your fuckin’ mind.”

“I’ll believe it when I see it, Kacchan.”

“I know what you’re doing.”

“It’s okay Kacchan, you don’t need to prove anything to me.”

“Fuck you, I’m gonna fuck your brains out in precisely thirty seconds. Sit your ass down and get ready.”

“Okay!”

He sat himself down on the mattress, propping the pillows up against the headboard and settling in comfortably. Katsuki just watched him, mentally rolling his eyes at the faded red boxers that Izuku still wore.

“You expecting me to stick it up the leg hole or something?” he asked, when Izuku caught him staring. “I mean yeah, it’s big, and I’m glad you have faith in my aim, but-”

“Enough,” Izuku squeaked, hooking his thumbs into his waistband. “I get it! I was just, um... Waiting.”

“For?”

Izuku gave him a pointed look, and Katsuki froze, blinking at him a few times in confusion.

“Oh,” he said finally, when Izuku’s eyes darted down. “Alright, gimme a sec.”

He ducked into the bathroom, washing the spicy greasiness off his hands, left behind from scoffing his chips. While in the bathroom, he tossed his clothes in the laundry hamper, returning butt-naked and smirking when Izuku’s eyes widened.

“What, you like what you see?”

“Don’t tease me, Kacchan.” Izuku pouted. “You know you look good.”

“But it’s so easy.”

Izuku bent his knee a little, subtly protecting himself from Katsuki’s gaze, and it took every ounce of willpower Katsuki possessed to keep from slapping it back down just to spite him.

“You’re the Allo one here, you’re not meant to be so nervous.”

Izuku burned bright red, and Katsuki gently joined him on the bed, kneeling near his feet and looking up at him pointedly.

“You good?” he asked.

Izuku nodded – enthusiastically, Katsuki had to admit, but still a little awkward.

“We don’t have to do this,” he reminded him. “If you’ve changed your mind. You told me that like five minutes ago, and the same applies to you.”

“I know!” Izuku assured him. “I just... I’ve kind of been... Thinking about this. For a long time.”

“About me?”

Izuku nodded again, and Katsuki’s lips curled into a smirk.

“Good to know,” he said, his amusement clear in his voice. “What, you been lying in bed thinking about me as you jerk off?”

“No! That would be creepy!”

“You are creepy.” Katsuki snorted. “All the mumbling and shit? Super creepy.”

“Wow, how romantic.”

“You asked to fuck, not to be wooed.”

“Can’t I have both?”

“Only if you ask for it.”

“Oh. Um, would you... Want that?”

“Are you asking if I have a big dumb crush on you like you’ve had on me since we were three?”

“Maybe.”

“Maybe,” Katsuki echoed. “Guess you’ll never know if you can’t ask properly.”

“Fine! You’re the worst.”

“And you like me.”

“Ugh. I don’t even know why, some days.”

“Tell me about it.” Katsuki huffed a little laugh. “I mean, I know I’m hot, but that’s not a good enough reason to like someone.”

“Stop insulting my best friend.”

“Idiot,” Katsuki chuckled, leaning over Izuku’s body until their hips brushed together, their lips only centimetres apart. “You get one for free. Any more and you have to take me to dinner first.”

“Deal.”

“Good.”

Izuku lifted his head, but Katsuki was quicker, pulling away and lowering himself between Izuku’s legs instead. He pushed a thigh aside, making space, and Izuku held his breath when Katsuki’s fingers curled around a pert butt cheek.

“You’ll need lube,” Izuku squeaked. “A-And I’m not... Stretched.”

“S’fine,” Katsuki assured him. “Relax.”

“But-”

“Deku. Izuku.” Katsuki cut him off quickly. “I’ve got you.”

Izuku teared up, but Katsuki chose to ignore it, instead diving down to lick over Izuku’s hole. Izuku squawked at the touch, clenching up immediately, thick thighs squeezing tightly around Katsuki’s head. He gently loosened them to give him room to breathe, wrapping his arm around one to keep it under control, and Izuku whimpered when Katsuki spread him open again.

“Relax,” Katsuki reminded him. “A little trust, nerd.”

“I do! I trust you!” he whined. “But it feels weird.”

“Why does it not surprise me that no one’s eaten you out before?”

“Is this what it feels like when I do it to girls?!”

“What the fuck, you’ve done this to girls?”

“Not on their ass.”

“That’s the part you think I’m focussed on?”

“You’re not the only one who fools around with our classmates, Kacchan.”

Katsuki froze, looking up to see Izuku’s flushed face, and for a moment he couldn’t even find words. Izuku stared back, confusion twisting his features into a strange grimace, and Katsuki loosened his grip on the freckled thigh.

“Is that what you think?” he asked. “That I’m fooling around with a bunch of random people?”

“N-No, I mean, I doubt it, but... You agreed pretty quickly. Didn’t seem... Surprised.”

“I know you,” Katsuki answered, shrugging. “Do you want me to stop?”

“No.”

“Okay. Then relax, let me... Take care of you.”

“I’ll try.”

“Wanna tell me about the girls?” Katsuki suggested, smirking. “Might get you in the mood.”

“I am so in the mood,” Izuku laughed. “Kacchan, look at me.”

He had to admit, the rock-hard dick right in his face seemed to agree with Izuku’s words.

“Point taken,” he said. “Can I keep going then?”

“Y-Yeah, I guess so? This is... new.”

“You deserve to get eaten out at least once in your life,” Katsuki told him, a little awkwardly. “Let me show you.”

“Okay. I trust you.”

“About time.”

He ducked down again, a little slower this time, and ran his tongue around the rim. He kept it light, gentle, and this time Izuku didn’t try to crush his head like a melon, which he figured was probably a good start. He felt the way Izuku squirmed under his touch, back arching, pressing his hips into the mattress and trying his best to keep them still.

“Feel good?” Katsuki prompted, following it immediately with a little lick across Izuku’s hole that made him twitch again. “Better?”

“Better,” Izuku agreed. “Still a bit... weird.”

“Okay.”

He took his time loosening Izuku up with his tongue, both his hole and his tense muscles alike, and slowly Izuku began to relax into his touch, to spread his legs a little wider, to let his breaths come a little quicker as his chest rose and fell to match.

“Done complaining?” Katsuki teased, when he paused for air. “Gonna be a good boy for me now?”

Izuku whimpered, feet reaching for Katsuki and scrabbling at his back to drag him back in, and Katsuki smirked as he obeyed. Izuku tossed his head back, gasping, and it took everything in Katsuki’s power to keep from laughing. He reached for Izuku’s cock, eliciting another desperate whimper, watching scarred fingers curl into the sheets and hold on for dear life.

“It’s okay,” Katsuki assured him. “You can let go.”

With one more whine and a few short thrusts of his hips, bucking up into Katsuki’s fist, Izuku came undone. Cum fell all over Katsuki’s hand, trickling down onto the sheets, and Izuku opened his mouth to apologise – cut off immediately when Katsuki squeezed him lightly, making him squeak instead.

“Feel better now?”

“How the hell do you do that?” Izuku asked, breathless. “Where did you learn that?”

“Not being horny helps you be objective,” Katsuki smirked, crawling up the bed to lie beside him, head propped on his hand. “Felt good, then?”

“You know it did.”

“You’re welcome.”

Izuku gave him a scathing look, only getting a smirk in return.

“Thanks,” Izuku conceded. “Sorry I uh, didn’t last long. Didn’t exactly get past the foreplay, huh?”

“Oral still counts.”

“Do you want me to... you know. Help you out, or something?”

“I’m good,” Katsuki chuckled. “I can do it.”

“Can I watch?”

“If you want. Pervy nerd.”

“Gotta learn how you like it for next time.”

“Next time?” Katsuki prompted, raising an eyebrow. “Someone has gotten bold.”

“Well we still haven’t technically done it,” Izuku pointed out, rolling over to grin at him, their faces only inches apart. “Gimme like twenty minutes and we’ll class it all as one, if you want.”

“We can do it again,” Katsuki shrugged, flopping onto his back to gain some space. “Just ask.”

“Yeah?”

“Yeah, but next time we’re doing it on your bed. It’s gonna suck washing this shit out of my sheets, you know.”

“Sorry.”

“It’s whatever.”

“If I promise to ask bluntly, will you promise to tell me if you’re not in the mood? I don’t want you to feel like I’m forcing you.”

“Don’t worry, if I’m not interested I’ll just tell you to go jerk off in the shower.”

Izuku offered him a pinky finger, and despite a roll of his eyes, Katsuki accepted. He linked them together, squeezing lightly, and Izuku beamed at him as they shook on it.

“One more question?”

“What now?” Katsuki huffed.

“Can I kiss you?”

Katsuki hesitated this time, and for a moment Izuku almost laughed it off, almost took it all back.

“Only if we’re dating,” Katsuki said finally. “I’m not gonna kiss you just because I ate you out.”

“Do you want to date me? You never really told me if you were, um, Aro?”

“I’m not,” Katsuki confirmed, lifting back up onto his elbow. “If I kiss you, you have to buy me dinner later.”

“Deal!”

He leaned in, closing his eyes and waiting, and Katsuki barely managed to contain a laugh. All the same, he pressed their lips together clumsily, lingering for a moment before they split apart again.

“I want fancy sushi,” he said, smirking. “You’re paying.”

“Jerk,” Izuku giggled, dragging him into a hug. “How about chicken nuggets?”

“I’ll take it.”

Katsuki yawned, dragging himself up to sit properly, and Izuku joined him after a moment, grimacing as the cum shifted around him again.

“Maybe a shower first,” Izuku suggested awkwardly. “And I’ll put your sheets in the laundry.”

“Shower first,” Katsuki agreed. “Sheets after you blow me later.”

Izuku burned bright red, but he nodded all the same, swallowing hard as Katsuki gave him that sharp smirk that always set his heart racing.

“Okay,” he agreed, making Katsuki’s eyes widen. “It’ll be my first time though, so be patient with me, okay? It might not be very good”

“It’ll be great,” Katsuki assured him. “I know you always put your best effort into everything.”

“Including understanding you,” Izuku finished, smiling to himself. “I’m glad you can tell.”

“Whatever.” Katsuki blushed, ruffling Izuku’s hair. “Go shower, I want my nuggets.”

“Okay,” Izuku agreed, planting another quick, chaste kiss on Katsuki’s lips. “I uh, I like you.”

“I like you too, I guess,” Katsuki grumbled, cheeks as red as his fiery eyes. “No Allo.”

“Yeah,” Izuku chuckled. “No Allo.”
