“My sweet baby boy,” Katsuki crooned, petting Izuku’s green curls. Izuku looked so perfect on his knees, legs spread to present the bulge in his tight briefs. He was gazing at Katsuki with that fuzzy look in his eyes, bright and sparkling and like there were actual fucking hearts in those depthless emerald irises.
Izuku’s cheeks were flushed pink, the smattering of freckles across his face stark and beautiful. Katsuki ran a gentle thumb across them, already imagining them coated in his cum. Izuku looked so goddamn beautiful with Katsuki’s cum streaking his face, claiming him.
“You’ve been so good, haven’t you?” Katsuki said, putting his hands in his pockets to keep from tearing that gorgeous face apart. There was something about that round, freckled face that just flipped that need for violence on in Katsuki’s brain.
He’d seen the kid late one evening getting hassled on the corner of his territory. Why he told Shitty Hair to stop driving, Katsuki never really understood. But one look at those dewey eyes and trembling form sent Katsuki into overdrive. When the car screeched to a stop, Katsuki prowled out like a man on a hunt, hand reaching for the gun holstered at his hip.
He didn’t recognize the extras, so they weren’t a part of his family. They looked like scummy little two-bit greasers, dressed like everything they knew about the mob came from shitty movies. They must have been new if they thought they could start trouble on Bakugou Katsuki’s turf.
“P-Please, it’s all I have, I don’t h-have anymore–” the little green haired kid whimpered. His pockets were turned out, an ugly yellow backpack splayed open on the sidewalk at his feet, textbooks and notebooks littered the concrete, pens and loose papers, and whatever other trash he kept on him spread around him. Most of it was worthless junk, but Katsuki’s eye caught on the keychain dangling from the backpack strap.
An All Might special edition enamel keychain, with the misprint of the comic book superhero’s costume, the colors inverted. Only a hundred were made before production caught the mistake and fixed it for the next run.
The two idiots were rifling through a beat up old All Might wallet, the tinkle of hundred yen coins hitting the ground echoing like raindrops as they tossed the kid’s meager money away.
“You really gonna be walking in our territory and not expect to pay the tax?” one of the idiots spat. Neither of them had noticed Katsuki strolling up, but the kid’s huge green eyes flicked to him.
To Katsuki’s surprise, it wasn’t fear that flashed across his face at the sight of the most notorious mob boss in the city, but relief.
The hell was with this kid?
“Guess if you can’t pay, we’re gonna have to take you in,” the other idiot sneered, leering over the kid and pressing him into the wall of the building. “Boss always wants whatever trash shows up on his streets cleaned up.”
“Boss, huh?” Katsuki said, looming behind idiot number one, who was tossing the empty All Might wallet into the gutter. “Who’s your boss?”
Idiot number one spun around, face drawn in a snarl. “How the hell do ya not know Shigaraki fucking Tomura? He rules these streets.”
Katsuki laughed, “That fucking daddy’s boy? Please. He doesn’t rule the shithole he crawled out of.”
Idiot number one pulled a switchblade from his pocket. “Watch your fucking tone, dumbass.”
Katsuki’s laughter stopped and the sudden silence was heavy. Before the idiots could blink, he pulled his gun and pressed it to idiot number one’s forehead.
“Don’t bring a fucking box cutter to a fight, idiot.” Katsuki drawled. The idiot’s eyes widened. “And maybe learn who’s fucking streets you’re on before you throw your tiny dick around.”
The idiot opened his mouth to argue but Katsuki was done listening. He clicked the safety and fired, blood splattering the wall. He turned to idiot number two, who was staring at him with his jaw on the ground.
“You’re… you’re him. The Dragon of Tokyo.”
At least idiot number two wasn’t as big an idiot as his friend was.
“Tell that Shigaraki twerp if he doesn’t keep to his little alleyway, it’ll be his head I bust open next. Got it?”
The remaining idiot nodded furiously and when Katsuki jerked his chin, he ran into the night.
“Sir?” Shitty Hair called from the car.
“Call Hanta and get this trash cleaned up. Find out who lives in this building and make sure they’re taken care of.”
“Yes sir!” Shitty Hair pulled his phone, already dialing up a number.
“T-Take care of them?”
Katsuki turned to face the green haired kid. He’d been quiet this whole time, eyes wide and staring up at him. The tears trailing down his cheeks mix with the blood specks spattered across his freckles. Katsuki stepped closer and to his amazement, the kid didn’t flinch, didn’t move away, just kept his big watery doe eyes trained on him.
Katsuki slowly raises his hand, hesitating before touching him, as if asking for permission. When he’s not pushed away and the kid gives a tiny nod, Katsuki cups his cheek and rubs the blood off his face.
“Pay for any damage, post security to make sure they don’t come back,” Katsuki said softly, as if talking to a spooked animal. Maybe he was; the kid was trembling under his touch. “Protect them.”
“I live in this building,” the kid murmured.
“Then I’ll take care of you.”
That was six months ago.
Katsuki had kept good on his promise. He was a man of his word, after all. He’d given Izuku a place to stay where he felt safe, took care of him, protected him. Izuku didn’t seem scared of the Dragon of Tokyo, didn’t seem concerned with what Katsuki did for the sake of his family. He was in awe of Katsuki, calling him his hero.
And soon he was calling him other things.
It started with Kacchan, then baby, then sir. Now? When he was on his knees at Katsuki’s feet, face so lovingly soft and body trembling in that familiar way that assured Katsuki he was just as needy for him as it was the other way around, when they were here, Izuku called him what no one else could.
“Daddy,” Izuku murmured, eyes trailing down Katsuki’s trim form. He was still dressed from his day, gray slacks held up by black suspenders, crimson shirt taut against his broad chest, the top buttons left wide open, sleeves rolled to his elbows. He’d made sure to clean up after he took care of business, but he could still feel the tacky blood on his hands.
He never wanted to spread that blood to Izuku again. He was too good for that, too perfect to be smeared in the red that defined Katsuki. Izuku was resplendent in green, from his bouncy curls to his wide, gentle eyes.
Izuku inched forward, slipping between Katsuki’s wide spread legs. His tucked his face into Katsuki’s thigh, mouth so close to his bulge, and he looked up through his lashes.
“Daddy, please,” Izuku begged so pretty, “let me suck your cock.”
“You want Daddy’s cock, baby boy?”
Izuku nodded, his nose brushing the side of Katsuki’s tent. “I’ve been a good boy. Let me show you.”
Katsuki grinned, hand coming back to pet Izuku’s head, fingers carding through his curls. “Alright baby, show me how good you are then.”
Izuku smiled, all bright shining sunlight encapsulated in such a small boy. They’d never cared for the difference in their ages. Katsuki may have more than a decade on the twenty year old, but he’d always felt like they were two pieces of the same whole, completing each other in ways no one else has ever been able to come close to accomplishing before.
Katsuki freed his cock, letting it spring up to smear the pre on his tip along Izuku’s cheek. It glistened a little trail between a set of freckles.
“Open wide, baby boy,” Katsuki purred, gripping Izuku’s hair.
“Yes, Daddy.” Izuku opened his mouth obediently, tongue out and ready to take Katsuki’s cock.
He wrapped his plush lips around Katsuki’s cock, tongue working the vein running along the underside of it, sucking it in deep. Katsuki pushed forward, knowing just how much his baby could take. Izuku could finally fully deepthroat Katsuki’s massive cock.
Izuku’s eyes rolled back into his head as Katsuki bottomed out, balls tapping his chin and cock sliding down his throat. Katsuki could see the bulge of it as he pressed in deeper, hand tightening in his curls as he pressed Izuku’s nose into his trimmed pubes. Tears filled Izuku’s eyes, spilling over hollowed cheeks as he sucked the life out of Katsuki’s cock.
“Mm, fuck, baby,” Katsuki growled, hips twitching, “you take me so good. Such a good little cockslut, mm?”
Izuku looked up at Katsuki and moaned against him, the vibrations against Katsuki’s cock were unreal.
“Fuck, baby, you keep doing that and I won’t be able to hold back,” Katsuki warned, pulling Izuku off his cock slowly, letting him catch his breath.
“Daddy,” Izuku’s voice was already rough and fucked out, “want you to fuck my throat. Please.”
Katsuki stilled. “You sure, baby boy?”
They’d only just gotten Izuku to the point where he wasn’t choking on Katsuki’s cock.
“Want you to fuck me, Daddy. Use me, please.” Izuku ran his hands up Katsuki’s thighs, nails digging through the fabric. “Wanna be your fucktoy.”
Katsuki growled, hands instinctively curling tight in Izuku’s hair. “Fuck, baby. Daddy’s going to fuck you good, then.”
Izuku damn near purred as he took Katsuki back into his mouth, lapping along his cock, sucking and drooling down his length. Katsuki gripped Izuku’s head and whispered, “Hold on tight, precious.”
Izuku fisted his fingers into Katsuki’s pants and opened his mouth wide. It was the last, teary look through his long, curled lashes that broke Katsuki’s self-restraint. He snapped his hips forward, bringing Izuku’s face down his cock until he was buried deep. Izuku’s eyes immediately burst with tears, eyes rolling back, and drool leaking from the corner of his mouth as Katsuki fucked his throat.
The sight alone was nearly enough to send Katsuki over the edge, but it was the muffled moaning vibrating around his cock that made the heated coil in his belly snap. Before he could come straight down his baby’s throat, he pulled free, leaving Izuku gasping and whining. Katsuki pulled his head back with a fistful of hair and stroked himself furiously until he was spilling over Izuku’s flushed and teary face, marking him completely.
With a face covered in strips of Katsuki’s cum, Izuku smiled dopily up at him. His hands ran up and down Katsuki’s thighs, and he hummed in contentment.
“Thank you, Daddy.”
God, the sound of Izuku’s truly fucked out voice was enough to get him hard again. His cock twitched in his palm.
“Fuck, baby, so good.” Katsuki brushed a curl out of Izuku’s face with tender fingers. “Gonna split you open on my cock.”
Izuku perked, raising up on his knees. “Please! Fuck me, Daddy!”
Katsuki chuckled. “Such an eager little slut, aren’t you?”
“Daddy’s slut,” Izuku hummed, reaching to hold Katsuki’s hand and nuzzle him.
“Daddy loves his little slut.” Katsuki murmured, dipping down to lift the boy into his arms. He was so small, but god, his ass looked fantastic when he was bouncing on Katsuki’s cock. “Such a good boy.”
Izuku preened. “And I love Daddy.”
Katsuki pressed a kiss to his temple and carried him to their bed. “Daddy’s going to take care of you.”
Izuku nodded, kissing Katsuki needily, arms wrapped around his neck. “Thank you, Daddy.”
