🩸🩸🩸🩸🩸

Katsuki never cared for sneaking out after dark.

He’d rather sleep than meet up with the extras to do stupid shit. His entire goal in life was to become the number one hero, and he couldn’t do that if he let meaningless bullshit get him into trouble.

He was sixteen with his whole life ahead of him as a Pro Hero, but he refused to fuck shit up now. However, tonight was a different story.

The police and hero radio he’d gotten from that shitty nerd Deku allowed him to listen in on where villains were attacking, and this asshole was causing enough havoc that All Might had been called in. Katsuki would see his hero fight up close and personal if it killed him.

Katsuki grinned as he crept toward an alleyway leading him to downtown. The chilly November air bit through his sleeping shorts and brought goosebumps on his arms despite his jacket, but that didn’t stop him.

He’d stay on the outskirts because, knowing All Might’s style of fighting, there would be a fuck ton of damage to surrounding areas. Although his determination to watch this battle rang high, he didn’t want rescue heroes to find him and take him away from the action.

A few more steps, and he entered the dark shadow of the alleyway. His eyes took their time adjusting from so little light, but he didn’t get the relish in the exciting adrenaline pulsing in his veins because a powerful force threw him against the nearest wall.

The worn bricks scraped against his cheek, making him wince.

“What’s a cute little kitten doing out this early in the morning?”

That voice was dark, full of mischief.

Silky strands of hair brushed against Katsuki’s collar as he swiveled his head to see who had the balls to attack him. He froze when he locked gazes with burning red eyes glowing in the dark like embers.

Crimson gear cogs with sharp spikes sticking out of them and a black harness leaving his muscular chest exposed told Katsuki who had him pinned and what level of fucking trouble he’d got himself in. Blood Riot was one of the worst up-and-coming villains out there.

He didn’t earn his name by being a petty criminal. He destroyed, maimed, and took what he wanted to further his agenda. What shitty luck Katsuki had to run into this asshole. The worst part was his quirk, hardening, was the perfect counter to Katsuki’s explosions.

/Shit!/

“Get the fuck off me!” Katsuki yelled, his hands igniting.

"Ooh, a feisty kitten! My favorite!”

Blood Riot grabbed Katsuki’s wrists and slammed them above his head, shifting them to one hand. The sheer size difference between them defied logic.

Katsuki only came up to the bottom of his chest, and Blood Riot had at least thirty kilograms of weight on him. The odds might be stacked against him, but Katsuki wouldn’t give up that easily. He bucked and squirmed, trying his hardest to break free of Blood Riot’s iron grip.

It did nothing but make him chuckle. Katsuki stiffened when something hard pressed into his lower back, and Blood Riot’s lips descended along his jaw.

“Mm, you’re so pretty,” he murmured, his free hand sliding down Katsuki’s side to cup his ass.

“You know bad things happen to pretty things when they’re alone like this.”

“Fuck you!” Katsuki spat, still struggling to break free.

“Yeah, that sounds good, doesn’t it?”

Katsuki’s jaw fell slack when he realized the meaning of his underlying words.

For the first time, Katsuki acknowledged that he was, in fact, sexually inexperienced. He was sixteen and should be raging hormones, but the only things he gave a shit about were being the best and All Might.

Fucking around with his classmates didn’t appeal to him, even though it seemed like they were all sucking faces and sneaking into each other’s rooms to feel each other up. Regardless, he didn’t want his first time to be getting sexually assaulted by the infamous Blood Riot.

“No!” Katsuki yelled. “I’m not doing shit with you!”

Blood Riot nipped along his jaw. “Aww, come on, Kitty.” He reached around to cup Katsuki’s crotch and massaged it. “Looks like you’re already into it. Your cock can’t lie to me, but how about this. I’ll be gentle this time!

Your pleasure only. I can be nice when I feel like it, you know.”

Katsuki made a choked noise as heat flooded him and radiated down his legs. No one had ever touched him like that.

Sure he got off in the privacy of his room or an empty shower before, but never with the help of someone else. He sank his teeth into his bottom lip to fight back a moan threatening to burst from his chest.

“Feel good, Kitty?” Blood Riot asked while continuing the sinful movement of his hand. “You gonna cum for me? I bet you’re so cute when you cum.”

“You fucking creep!” Katsuki tried to yell, but it came out as a whisper. “I’m sixteen, and stop calling me kitty!”

“So?” Blood Riot asked, not acknowledging Katsuki’s request to drop the nickname.

Katsuki didn’t have an answer to that. He’d tried from trying to pull from Blood Riot’s grip, realizing this villain would have his way with him.

His cock ached, and his mind raced, hating that he wanted more of that sensation, more of Blood Riot’s touch. Was it because Katsuki hadn’t been touched this way before, and the delicious newness had taken over, or was it because Blood Riot was hot as shit?

Katsuki hated that the thought even ran through his mind, but he wasn’t blind.

Just in denial.

He couldn’t hold back his groans of pleasure any longer when Blood Riot dove his hand into his pants to stroke him over his underwear.

Katsuki’s knees buckled, but Blood Riot held him in place. Throbbing ached through his groin, Katsuki’s breath coming in short gasps the longer he teased him. Fuck, he was already so close to finishing.

But then Blood Riot stopped. He didn’t remove his hand, though.

He focused more on running his tongue over the hollow of Katsuki’s throat, eventually tiring of bending over and releasing Katsuki’s wrists to grab him around the waist and lift him off his feet.

That was Katsuki’s moment to keep fighting, blast Blood Riot in the face and take off, but his brain had forgotten that he needed to escape.

“I just wanna fuck you right here,” Blood Riot sighed, “I don’t wanna hurt you, though. I may be a villain, but my cock is huge.

I’ll have to prep you thoroughly for that.”

He spoke as if there would be a next time. Why did that make lust flood his body? It made no logical sense.

Anyone rational person wouldn’t want to give in to a sexual attacker, but Katsuki’s blood thrummed, ready for more of his rough hands palming him.

“What are you gonna do then, hah?” Katsuki taunted, hooking his arms over Blood riot’s massive forearm.

“Tch, you’re a shitty villain attacking a teenager!”

“Oh, you’re more than just a teen,” Blood Riot said with a laugh. “I know all about your quirk. You’re gonna be an adversary for me one day. I wanna enjoy you now so I can compare when I fuck you later down the road.”

“That makes no sense!”

“It does to me!” Blood Riot chirped. “How about you just focus on how I’m making you feel? You’re so hard for me, leaking pre-cum and everything. Mm, I wanna just lick it all off.”

Fuck, Katsuki almost creamed himself just from those words.

Blood Riot kept working his hand over his aching length over his clothes, increasing the desperate need for skin-to-skin contact. That, coupled with his sharp teeth scraping over Katsuki’s shoulder, digging in for a slight sting, left Katsuki feeling things he’d never had before.

When Blood Riot finally dove his hand into Katsuki’s boxers, a sense of relief and anticipation washed over him.

Until Blood Riot stopped stroking him /again./

“Why do you keep stopping?!” Katsuki demanded, throwing an irritated look over his shoulder.

“If you’re gonna get me off, hurry up! I have somewhere to be.”

The words barely left his mouth before Blood Riot released his waist, dropped him on shaky feet, and wrapped his hand around Katsuki’s throat. He tilted Katsuki’s head back, locking him in place.

“I’m finished with you when /I/ say, Kitty. Hissing at me won’t make me move any faster because we both know how into this you are.”

Blood riot removed his hand from Katsuki’s pants to spit on it and slip back inside. Oh, fuck.

That plus precum made the slide of his hand over Katsuki’s dick smoother, more intense. His legs started shaking as Blood Riot worked him over.

“M’not,” Katsuki lied, his eyes screwing shut as the coils in his belly heated further.

Blood Riot tsked.

“I don’t like liars, Kitty."

"Didn’t your parents teach you how bad that is? Let’s see if we can get some truth out of you, hmm?”

Katsuki realized what a mistake that little white lie had been when Blood Riot pulled him to the edge of bliss only to yank him back off it.

Four more times, he jerked Katsuki until he was seconds from seeing stars, only to stop. There was nothing more on the face of the planet he wanted more than to cum all over Blood Riot’s hand.

“C-come on!” Katsuki pleaded, his voice breaking, hands popping against the wall.

“I’m so fucking close!”

He’d given up some time ago and surrendered without even realizing it.

Katsuki had even widened his stance to give him better access, but Blood Riot took his time, enjoying making Katsuki break further with every squeeze of his cock and roll of his balls in his palm.

“I can leave now since you don’t like what I’m doing,” Blood Riot said nonchalantly in between kisses to Katsuki’s red-blotched shoulder. “Leave you high and dry to stroke your cock while thinking about my touch.”

“No, I don’t want you to stop!” Katsuki blurted out before he could bite them back.

“See, honesty isn’t that hard! Since you’re being such a good boy, I’ll let you cum.”

Blood Riot hooked his arm around Katsuki’s neck and hoisted him off the ground.

He coughed, clawing at Blood Riot’s hardening arm, even letting off a few explosions, but it did nothing. Blood Riot’s hand wrapped around Katsuki’s erection and stroked him faster. Moan and sobs of pleasure poured from Katsuki’s lips.

There was nothing he could do to stop them, and right now, he didn’t give a shit about that.

“That’s it, Kitty. Cum for me,” Blood Riot whispered in his ear. “Lemme see what you look like when you blow your load.”

Katsuki knew his face was stained red from embarrassment, but Blood Riot stole his focus. It didn’t take more than half a second for Katsuki to orgasm, hips jerking forward with every spurt of cum he shot into his pajama shorts.

Blood riot released him, and Katsuki crumbled to his knees, coughing and putting a hand to his neck. He turned to shoot Blood Riot an angry glare, who was busy licking Katsuki’s spend off his fingers.

“So good,” he moaned, palming his groin.

He turned his intense gaze on Katsuki and grinned. “Next time, I’m gonna fuck you, Kitty. I think you’d look so hot bouncing on my cock.”

“I’m not doing that!” Katsuki sputtered, scrambling to his feet.

Blood Riot turned and walked out of the alleyway. “Sure you’re not.

See you soon, Kitty!”

Then Katsuki was alone. He stared down at the huge wet spot staining his crotch and turned to walk home. He’d have to see All Might battle another time. Katsuki needed to clean up and figure out what the fuck had just happened.

That and how to prep for anal. Not because he’d let Blood Riot fuck him, but because he was curious. That was all.
