Katsuki wakes up tied to a chair in a dark room. Tape across his face to muffle his shouts and rope burning into his arms from his struggles. He thought at first that it was a birthday prank from the squad, but they wouldn't leave him naked.
"Oh you're awake." A small voice says to his right. It's too dark to see the owner but it sounds make and familiar. He hears them shuffle about and a match is lit. It touches to a sparkler on top of a cake. In the flickering light he sees a face that he thought was gone forever.
Deku...
The ghost from his past shuffles forward, the feeble light paints a grim picture. Deku is perhaps scrawnier than he was in middle school, his freckles pale and eyes hollow. But he still manages a wobbly smile for him.
"H-happy Birthday Kacchan."
There's so much he wants to ask. Where's he been the last 5 years? Is he okay? Does he know Katsuki is sorry? Why is he naked?
"What the fuck?!" His jumbled brain spits out, but it's all garbled by the tape.
That shaky smile falters a little but the nerd presses on. "Also congrats on-on your hero debut. I'm sure you'll make it to #1 in no time! Kacchan's amazing after all!"
He set the cake down on a small side table he hadn't noticed earlier and climbed into Katsuki's lap.
His skinny fingers played with the hair at the nape of his neck. It sent a shiver coursing through his body. He struggled against the bonds. If he could just twist his hand...
"I-i wanted to get Kacchan something nice but I don't have a lot...So I'm giving you the only thing I have left."
Before he could muffle out a question of what the hell that meant. Deku slipped to the floor between his knees. He shouldn't be getting excited by this! Shouldn't be groaning as Deku tentatively licks his cock to life. Fuuuuck! He sucking him in! How the hell was the nerd able to take him all the way?!
It was sloppy and amateurish, but by God did it feel amazing! His throat constricted around the top and Katsuki threw his head back with a wail. The wet heat of his mouth slipped away and he involuntarily tried to chase it with his hips.
Scarred fingers lazily pumped him and he realized Deku's other hand had disappeared behind himself.
He wanted more light. Deku was probably blushing to high hell, he wanted to see it!
Deku was trembling when he crawled back into Katsuki's lap,his cock rested easily against his crack. He gyrated his hips and rubbed his tiny erection against Katsuki's abs. "Mm Kacchan your so b-big! I'm not sure it's going to fit!"
Katsuki thrashed his head side to side. Deku mistook his frenzy for rejection. "I-I know I'm not a pretty girl like you're. ..used to, but I'll try my best!"
He tried to take Katsuki all in one go. He mewled when the fat head breached his tight little hole. His face scrunched in pain halfway down. Katsuki wanted his arms and mouth free. He'd make his nerd go slower, coo assurances in his ear. Tell him he's doing so good—no need to rush.
But all Deku would have heard was the whine he let out. As they tight, tight heat enveloped him in one swoop. Deku went stalk still, mouth bobbing open and tears dripping from his eyes. Damn it! Katsuki will kill him if hurt himself!
Slowly Deku relaxed a bit. He lifted himself to drop back down again and again. "Unf-ah! Kacchan! Kacchan's inside me!"
He met Deku's movements with thrusts of his own, absolutely delighted when Deku squealed with each brush of his prostrate. He wanted to bite and suck on that pale neck in front of his eyes. Maybe dig his fingers into the nerd's hips and leave burns there.
Never in a thousand years did he imagine he'd see those green curls again. He'd thought he'd lost Deku to some stupid words and a bridge. Turns out the little asshole was alive this entire time and harbored feels for Katsuki as well.
Deku's pace got quicker, sloppier. That hot channel continue to twist and massage him just right. Fuck middle school him for denying him this pleasure because of internal homophobia
"Ah! Oh! Ah!"
He wanted to swallow all those sweet sounds escaping through chapped lips. He wanted to devour every part of the nerd!
Much too soon, Deku's head flew back in a high pitched scream of pleasure. His ass locked down on Katsuki's cock and strangled his orgasm out. Like a good boy Deku kept bouncing to wring out every last drop from Katsuki.
He fell forward, face buried in Katsuki's sweaty neck. They both painted heavily. The nerd's lips tickled his skin as he spoke. "Thank you Kacchan, thank you for letting me give you a present. I know a quirkless nobody's virginity isn't much..." Oh fuck he was going to get hard again! "I...just wanted to give you something before you're too far out of my reach," tears splashed coldly against his overheated skin. "I know you're going to be #1, cause Kacchan's amazing."
Silence covered them, he didn't mind the cooling cum pressed between their stomachs. It meant it wasn't a dream that Deku really was here. The last of the sparkler died out as Deku pressed a kiss to his tape covered lips. The darkness pulled at him, the lethargy of a body wracking orgasm settled into his bones. Despite being tied to a chair, the comforting weight on his lap nudged him to sleep.

Katsuki woke up to sunlight hitting his face and a cheap box spring under him. He'd been cleaned up and dressed. The only trace of Deku was the little cake on the side table. He wanted to smash it in frustration but settled for angrily eating the entire thing.
Goddamn nerd remembered ancho Chile chocolate was his favorite.
/*several weeks later*/
Izuku ducked into the alley unable to deny his grumbling stomach anymore. He also wanted to get off the street. He'd seen Pro-Heros Red Riot and Pinky across the street on patrol. A pink hand pointed at him and said something. The red head did a double take before pulling out his phone.
The homeless population had grown in the past few years. Heroes were now instructed to "encourage" them to move along whenever seen. It really turned into MS bullying all over again. He'd already dealt with another hero earlier, his scuffed knees and elbow still hurt from when he'd been shoved into the sidewalk.
So he fled into an alley. The buildings nearby had several restaurants, he reasoned he could scrounge some food from the garbage. Maybe enough that he could leave the area safely. He hit pay dirt! One of the cans was loaded with expired cobini bentos!
He'd only just started pulling them out when a heavy weight slammed into him from behind.
He was wrapped up in a crushing bear hug which he couldn't wriggle free of. "Let me go!" He shouted, terrified. He's heard of this happening. Villains (and civilians) had no qualms about taking their various frustrations out on the homeless.
"Hah?!" A deep raspy voice barked in his ear. The scent of burned caramel could finally be picked up over the trash. "Like fuckin HELL I'm letting you're scrawny ass go! Took me fuckin' weeks to find you!"
"K-kacchan?!"
"Yeah dumbass!" He growled and started walking back out on the street. Oh no was he going to be arrested? He couldn't afford the tickets, he'd be stuck in jail!
"Yo, Bakubro!" Red Riot and Pinky jogged up to them. "That's him right?"
"Geez Blasty!" Pinky snickered. "Let the poor guy walk on his own."
Izuku's legs dangled a foot or two off the ground, Kacchan bark above his head. "And give him a chance to run? Hell no!" It felt like Kacchan actually nuzzled into his hair. What was happening?! "Can you two cover the rest of my shift?"
"Yeah, I could use the overtime really." Pinky gave him a thumbs up.
Red Riot wiped away fake tears. "I love a happy ending!"
"Fuck off!" Kacchan was already stomping away, izuku still strapped to his chest by those toned arms.
They got odd looks on the side walk, he felt ridiculous. "Where are you taking me?" Jail, his mind supplied or a shallow grave. After all he did...rape the hero currently holding him.
"Home." He answered simply as they boarded a train.
"What?"
"Did I stutter?" He snorted. "We're going home." He caught Kacchan's eyes in the window reflection. There was a hunger there that threatened to devour him whole. " 'sides..." Izuku jolted when Kacchan nibbled his ear. "Gotta show you how much I appreciated my birthday gift."
His heart rate picked up and he realized that was not a flashlight grinding into his ass.
"Am I..." he licked his lips. "Am i dreaming? "
A deep chuckle vibrated through him from behind. "If you are, I'm making sure you never wake up"
