Act One Chapter 18

Tuesday, May 6, 2042

It was so warm.

Katsuki snuggled deeper into his pillow, the surrounding warmth helping him relax. He felt the weight behind him move, and the dip in the bed disappeared. A creak and quiet footsteps followed.

Katsuki rolled over, peeking through tired, squinted eyes as Izuku tiptoed around the room.

It was still dark outside; Where was he going?, Katsuki thought.

Izuku slipped on his shoes and buttoned up his shirt, then went back to the bed. He leaned over Katsuki and smoothed his hair back, planting a kiss on his forehead and cupping his cheek. Katsuki placed his hand over Izuku's scarred one.

"Where are you going?", the blond whispered, voice still gruff from sleepiness.

Izuku's thumb rubbed underneath a red eye. "Don't worry," he reassured with a soft smile. "I've got something to take care of real quick. I'll be back in a minute."

Katsuki slowly sat up on his elbow. He leaned forward to gently peck Izuku's lips.

"Stay safe. Don't die, or I'll kill you.", Katsuki murmured, letting Izuku run his fingers through his hair.

Izuku chuckled, kissing him again. "Alright, Kacchan. Go back to sleep."

The blonde nodded, his eyes closing. Izuku gently pushed his head onto the pillow and pulled the covers back over Katsuki, before closing the door, his footsteps echoing in Katsuki's head.

"Mm, ngh~"

Wet kisses were pressed against Katsuki's neck, and sucking newer hickeys onto old ones. The mouth pressed against a spot under Katsuki's ear, sends shivers down his spine.

Large hands smoothed up and down his waist, keeping him in place on his stomach. Smooth lips pressed against Katsuki's ear, whispering in a low voice.

"I'm back Kacchan."

Katsuki raised a hand behind him to thread his fingers in Izuku's hair.

"Couldn't you have waited 'til I woke up to get frisky? Its still early."

Izuku chuckled and pressed his chest against the blonde's back "Sorry. But," his hands settled on Katsuki's hips. "Is this okay? Or should I stop?"

Katsuki pulled the man's head down, letting him kiss along his jaw. "Dumbass. Keep going." He planted his hands against the bed and arched his back, grinding his ass back onto the greenette's erection. He could feel the grip on his hip tighten, just a bit.

The hands on his body leave for a second and Katsuki is left confused, but arms come around his front and quickly set to work on unzipping his jacket.

In one swoop, the jacket was pulled off, and Katsuki's stomach and lower back was left cold. Katsuki nearly choked at the sudden movement, and went to make a derogatory comment, but his annoyance was washed away as Izuku ran a hand over the exposed part of his back, one hand going back to his hip.

It wasn't even one of his erogenous zones, but Katsuki was a bit overwhelmed at the warm hand massaging his back.

Katsuki rose up onto his elbows while Izuku's hands trailed higher, roaming his abdominal muscles. Katsuki glances down under his eyelashes. He could see the hands moving through the fabric of his shirt. Katsuki immediately shuts his eyes and gulps, gripping the sheets as he tries to erase the arousing image from his mind.

Katsuki's legs started to shake as Izuku pressed a kiss and soft bite at the nape of Katsuki's neck. The blond could feel Izuku's own shaky breath and reeled at the oversensitivity.

Izuku pressed another kiss on his skin, then another, and another, while his hands wandered upwards under his shirt.

Katsuki was glad his eyes were closed as his mouth hangs opens, and he tries to make as little sound as possible as Izuku groped and squeezed at his pecs, thumbing over his nipples and still nipping at the sensitive areas of his neck.

Katsuki felt like there was a storm in his stomach, trying to escape in the form of whimpers and moans, and he struggled to keep them inside. His guard slipped momentarily and he broke into a series of high pitched moans as Izuku pinched and tugged at his nipples, Katsuki's head hanging loud between his arms.

As Izuku rolled and groped, Katsuki wondered how he got in this position; Underneath sex-on-legs Adonis with said man acting as if his pecs were tits. Katsuki could feel Izuku's strained erection pressing against his ass, and he couldn't move even if he trusted his body to work through the mind-numbing pleasure.

Katsuki gasped, no, moaned for Izuku as the green haired man twisted one of his nipples while simultaneously biting lightly into the side of his neck. Lightning shot up Katsuki's back and the bed shook from the force of a single buck that had the headboard slamming into the wall.

He couldn't, he just couldn't. He was too far into this game and too far gone and too far into him to care about how he sounded or how loud he was, his breath punched out of him and his knees shaking again.

"Fuck, 'Zuku! I-... hahh, shit, ah- fucker-mm, shitty AH-ss!"

Izuku froze behind him for just a second, just long enough for Katsuki to notice. Then he straightened and slid his hands slowly, teasingly, from Katsuki's pecs, down his abs, over his waist to settle gently at his hips.

Katsuki used the break to try and catch his breath, but Izuku had other ideas. Suddenly, without warning, the hands on his hips gripped hard, pulling him back a few inches and making his hands scramble for purchase at the sheets as his ass was forced once more into Izuku's hard-on. Izuku splayed himself over his back, his mouth by Katsuki's ear and he whispered in that godforsaken voice-

"Don't be mean Kacchan. Be nice for once, and call me by my name. What I like."

Katsuki's eyes fly open and flutter in recognition as the words flood his mind, and it checks every box on his 'fuck list'. The commanding, dark pitch of his tone coupled with an insulting undertone hit Katsuki hard.

"Fuck you.", he grits out, keeping his defiance.

"Not with that attitude," Izuku chuckled darkly. "Is that your way of begging? Try harder, love."

Katsuki felt his cheeks heat up and his chest burn with embarrassment as his cock throbbed between his legs. Still, he wanted it. Katsuki wanted him so bad, and he had no idea why. But what he did know was that it felt so, so good; So, he swallowed his pride with an audible gulp as he proved to himself that he could take what was being given to him.

Voice sounding rough and foreign to his own ears, Katsuki tested it out.

"Please 'Zu- Daddy."

The name feels both foreign and familiar on Katsuki's lips. He drawls over the syllables as his tongue reacquaints itself with the shape of Izuku's oh-so-loved nickname. It's been a while. It doesn't make Katsuki cringe as much as he expected it would.

The grip on his hips released and Katsuki breathed out through his nose to steady himself as Izuku placed another sinfully wet and open-mouthed kiss against his pale shoulder and mumbled against his skin.

"Good boy... Thank you."

Before Katsuki could respond, he was pulled backwards again, away from the pillows, and suddenly he's on his knees and it's disorienting. Katsuki didn't know where to put his hands now that they have been removed from the sheets, so he just knelt there, dazed.

Izuku grabbed him and in one quick moved, turned them over, Izuku with his back against the headboard and Katsuki in his lap. He pulled the blond close, much too close with how heated Katsuki felt, scarred arms circling around his waist, pressing their erections together. Katsuki grunted and his own traitorous hands find Izuku's shoulders.

"Can I kiss you?" Izuku asked, almost back to his normal inflection. He still sounded much more sure and confident than Katsuki felt, but there was an undertone of something deeper in his tone.

A question, probing and searching, asking for permission. Asking to go further. To cross more boundary lines and tear down the limits they hadn't spoken of in their relationship before. But Izuku's eyes were so green and pretty and his lips were shining and Katsuki wanted this. He really wanted this.

So, he nods his head, and Izuku's lips are on his. Izuku wasted no time in slipping his tongue over the seam of Katsuki's lips, letting himself in and forcing a muffled moan out of Katsuki. It's weird and different from before, and it doesn't feel rushed as much as it is extremely hot. After taking a second for his brain to stop short-circuiting, Katsuki kissed back. The wet smacks of his tongue against Izuku's left his head spinning, and Izuku kneaded his fingers into the skin of his thighs and oh- Oh yes, that feels very good.

Once again Katsuki was being pulled, higher onto Izuku, being manhandled and shoved into straddling Izuku's lap in such a way that reminded Katsuki of just how strong Izuku was.

(How much stronger Izuku was than him, how he wouldn't be able to do anything if Izuku wanted something-)

All the while Izuku kept stealing wet, seething kisses from his lips so fast that Katsuki's mouth couldn't keep up. So Katsuki just let his body be moved, and moved his hands to Izuku's hair and gripped it firmly like Izuku did before, and let himself be kissed.

Katsuki's fingers scritched at Izuku's scalp and Izuku groaned. The blond noticed, and pulled. Hard.

Izuku's head nearly slammed into the headboard and he moaned loudly between their lips. Something inside of Katsuki shone with pride, but that was quickly swallowed by the storm brewing again in his groin as Izuku reached under Katsuki's shirt to pull it up and over his head.

Katsuki had to lean back and trembled as he lifted his hips, trying to balance himself as Izuku all but ripped his shirts off of him, pulling the fabric down Katsuki's hips.

Katsuki gripped at Izuku's shirt and shivered at the cold before realizing Izuku still had all his clothes on. He pulled at the fabric, and slowly unbuttoned it with shaky fingers. Once that was off, Izuku undid and slipped off his pants, holding Katsuki in place. Izuku drew him close again as an apology and drug his finger over one of his hardened buds. Katsuki sighed and let himself watch. His face was positively burning with a crude mixture of embarrassment and arousal, but this wasn't a view he wanted to miss out on.

Izuku ground his hips up, his erection rubbing against Katsuki's. Katsuki moaned and dug his nails into Izuku's shoulders.

"Fuck, Kacchan," Izuku mumbled, half to himself, pressing up against Katsuki perineum through his boxers. A wet spot grew on the front of their boxers, and Katsuki nearly screamed.

Katsuki wished that he would shut up and cut to the chase. Izuku lifted Katsuki up off his lap and watched Katsuki's boxers stick to his sweat-laced body, and looked up at the blond's face with dark eyes. Izuku's pupils were blown wide, almost swallowing was left of the green.

Izuku fingered Katsuki's waistband, glancing at him with a question in his eyes. Katsuki nodded with red creeping down his bare chest despite the chill. Izuku peeled at the cloth, peeking inside and watching a string of white connecting to the clothing.

"Look at how wet you are for me..."

Katsuki let out a ragged, guttural noise as Izuku's words shot straight to his weeping cock. He was so hard it was starting to get painful. Katsuki didn't think he could wait any longer, but no matter how much he shifted his hips or tightened his grip on Izuku's shoulders, Izuku wouldn't let up on his slow grinding.

Katsuki's waistband snapped against his skin. High-pitched 'ah, ah, ah's spilled out of Katsuki as Izuku pressed against that deliciously amazing spot. Izuku slid his cock under Katsuki's balls, groaning as his leaking tip was ground on. He rolled their hips togethers and pinched perky pink nipples, still mumbling lowly. "Beautiful. I love seeing you like this, you know. All strung out and desperate for me to touch you. Gosh, I could get used to this..."

It was that voice. Katsuki was completely powerless as he actually whined high in his throat and rested his head against Izuku's shoulder. Katsuki wouldn't've been surprised if steam was coming out of his ears, because his entire body was threatening to burn him from the inside out.

Izuku sped up, his thrusts rocking their body, droplets of sweat dripping into the chiseled dips of his body.

Katsuki could feel himself getting closer to the edge, and Izuku noticed. He slowed the rolling of both his thumbs and hips, panting heavily with a triumphant smile. Katsuki could still watch Izuku tease him from where he was. But truly, Katsuki wanted nothing more than to be able to close his eyes and dissolve into the pleasure coursing through his body, but Izuku was in control, and Katsuki had no idea what plans Izuku had in store for him while he was so close.

Izuku presses that spot again with his twitching cock, in circles that have Katsuki whining and moaning louder than he would've liked, and Izuku continued.

"I know, fuck, I know. But shit, Katsuki, you don't have any clue what this-... oh. Fuck, - say please?"

Katsuki knew that he was just screwing with him at that point. Izuku was just testing Katsuki's limits, seeing how far he could push before something broke. But Katsuki was already to far gone to care, so he just closed his eyes from the sudden onslaught of sensations from his lower half eating a hole through his common sense, and responded immediately, in a desperate whisper he had never heard come from his mouth.

"Please, please, fuckkk 'Zuku, please!"

It was quiet enough that if Izuku hadn't been so close, he wouldn't have be able to understand the rushed plea.

Then there were hands grabbing his ass, squeezing him briskly and grinding hard and Katsuki could almost cry. He didn't, but he could had. He seriously considered it as Izuku pulled at his swollen nipples, still humping hard enough that it had Katsuki bouncing on his lap and clinging onto Izuku for balance.

Katsuki let out a surprised gasp, leaving his eyes shut as he tilted his head down and arched over Izuku he sped up, immediately setting a punishing pace on his pleasure spots, clearly not meaning for Katsuki to last. Katsuki knew this was the final stretch. He was embarrassingly close minutes ago, and Izuku's thrusts and pinching are sometimes mismatched or too hard, but it was still so good because it was tingly,and hot, and good around him and it was everything he needed.

"-yes, yes, yes, fuck, yes, ah- mm, ahh, yes-!" Katsuki could barely hear his own voice as he moaned unabashedly. Izuku shook, clearly nearing his breaking point.

Katsuki's toes curled and his body felt warmer than ever as Izuku ran his mouth lazily over his throat. Izuku leaned forward, thumbs still rubbing furiously over his nipples. Izuku pressed a kiss to Katsuki's cheek and whispered to him. Katsuki knew he was a goner.

"That's it, Kacchan. You've been so good. Cum for me, Katsuki."

In a blind panic, Katsuki raised a fist to his mouth, shoving his knuckles under his teeth to quiet himself. His moan still managed to slip out, though it fizzled out.

Katsuki's orgasm hit him like a freight train. The pain of his teeth against his flesh combined and blurred with the white-hot ecstasy crashing over him as his chest pushed forward to rub against Izuku's fingers, his ass bouncing and hips rutting down meet Izuku's thrusts. Katsuki came harder than he had in a very, very long time. It was completely silent all for panting the and squeaking noise the bolts of the mattress made as the two ruts against each other, hips thrusting again, and again, and again.

Izuku froze, and a whine squeezed out of his throat. He trembled under Katsuki, his head dropping back. An orgasm he'd held in for too long erupted out of him so hard he blacked out momentarily. He woke up though. Thank Gosh.

Letting out a sharp breath, then another, Katsuki sucked oxygen into his lungs greedily, and Izuku slowed his hips and hands, giving the blond a few last firm thrusts before dropping his hands onto the sweat-soaked sheets. The tension in Katsuki's hands lazily draped over Izuku's shoulders as he felt his muscles relax.

Katsuki sat back on his haunches, his thighs aching and asleep from the loss of blood flow, and Izuku's hands move to rest on his bruised thighs. Katsuki pried his eyes open to look at him. Izuku's curly hair was even messier than usual and his lips were bruised red from kissing. A healthy flush flooded over his features, emphasizing his freckled cheeks as he looked up at Katsuki through his eyelashes. Katsuki was sure he didn't look much better himself.

Izuku's hand slipped around Katsuki's hips to his ass. It wasn't sexual, but it gave Katsuki the support he needed to relax his posture in Izuku's lap and move his calves from underneath of his thighs to splay out on either side of the man. Izuku either clearly didn't care that the blond invited himself to plop his ass down on his lap, or he just didn't have the energy to comment on it, seeming to let Katsuki be the first to break the silence.

"Fuck're you lookin' at?" Katsuki tried, but no spite rose in his voice. Instead, his words were timid and defensive, almost nervous. Almost. Mostly tired.

Katsuki didn't know where they were supposed to go from here. He'd never done anything like this before; With anyone. He was too focused on his schoolwork to think about relationships.

"You," Izuku responded easily, without breaking eye contact.

Katsuki felt something rise in his chest and it forced him to look away from the man. Izuku let out a soft chuckle, and Katsuki knew it was because he was pouting, but he didn't have enough energy to be mad about it. In fact, he was in a pretty goddamn great mood right about now, and unfortunately, it's entirely Izuku's fault. At least he'd be able to go back to sleep without Izuku's grabby hands.

"Well!?" Katsuki forced out, shifting in his own mess of cum stained clothes. "You had enough, or does this still need attention?" Katsuki demanded, rolling his hips to press down against Izuku's softening cock, and watched as the green haired man's eyes flutter shut.

Izuku pulled his bottom lip between his teeth and hissed in pleasure at the action. Two hands fly up back up to his hips, either to hold him still or to push him back down, Katsuki didn't know.

"No, no." He breathed, twitching. "I've had enough. Don't need anything else."

Katsuki nodded and yawned, pushing Izuku down to lay on the bed. He pulled the covers over them, resting his head on the man's heaving chest. Strong arms wrapped securely around him and holding him close to the too-warm body.

Katsuki fell asleep to the irregular heartbeat in Izuku's chest.

Bum, ba-ba bum. Bum, ba-ba bum. Bum, ba-ba bum. Bum bum... badum... bum bum...
