Chapter Text
The storm cuts off the film they were watching and Katsuki groans loudly at the inconvenience. They can only see each other's shadows in the dim night light emitting from the window. Katsuki stands to go find a flashlight when a hand catches his arm. He turns. Deku is staring at him in the darkness. Katsuki almost shouts at him to let him go but he just sits down without a word.
Deku stays seated behind him, and only the sound of their breath could be heard in the room. Deku’s hands traced the backs of Kacchan's gently, before slowly making their way up to his arms and onto his shoulders. Katsuki can feel his breath on the back of his neck. He tenses. He’s not sure what’s going on or why he’s not doing anything about it. He opens his mouth to complain.
“Kacchan,” Deku’s voice whispers from behind him. “Let’s stay here.” Deku knew his words were bold, but he felt emboldened. By the darkness and by the nature of their new relationship. He puts his arms around Katsuki's waist and breathes softly on the back of his neck.
“Have you lost your mind you damn nerd? Get off me!” Katsuki growls at him. Of course, Katsuki doesn’t move, he waits to see what comes next. Deku’s arms tighten around him and he can feel his breath in his ear.
“Kacchan,” Deku breathes quietly, sending shivers down Katsuki's spine. “It’s so dark, I can barely see you.” He says, his voice teasing. He pulls at the edges of Katsuki's shirt, implying he means to pull it off. After feeling no resistance, Deku lifts his shirt over his head and tosses it across the darkened room. He removes his own next.
Katsuki gasps as he feels Deku’s bare chest against his back, skin warm and tingly. He’s overwhelmed. His feelings evade his vocabulary. He breathes heavily and leans instinctually into Deku's embrace. “Deku,” He says, quietly. “What is-What are you-”
Katsuki's words were cut off by soft lips pressing against his, a hand gently caressing his throat. Then, he’s quickly unhanded, untouched in the dark. Katsuki turns his head to see if Deku is still there, despite feeling his weight still on the bed behind him. Deku waits for Katsuki to decide if he wants to continue. He stares into Katsuki's fiery burning eyes, with a soft yearning gaze. Katsuki looks away sheepishly, incredulous at Deku's assertive behavior. Katsuki leans forward, almost against his own will and the two connect their lips once again, this time more forcefully. Deku slides out from behind him and gently presses on Katsuki’s shoulder.
Katsuki resists slightly, unsure what game they were playing. “Kacchan,” Deku says with a breathy giggle, “Lay down for me.” Katsuki obliges slowly, laying down on his back. Deku looks down at him and Katsuki closes his eyes. He can barely look at Deku without feeling heat flush his face. It’s dark, but Deku’s large green eyes glisten from the dim light through the window. Deku sighs in awe. “Amazing,” he whispers. Katsuki can feel his face turn hot. He brings his arm up over his face to shield himself from the intensity. Deku throws a leg on either side of the half-dressed body beneath him and leans forward. Soft breathy kisses gently brush Katsuki’s chest and make their way down to his belly button. Katsuki shivers with each touch of the boy’s lips. He’s-nervous. And surprised. Why wasn’t Deku nervous? He looks down at the top of the boy's curly head. He seems so confident, meanwhile Katsuki doesn’t even know what to do with his hands., which are rigid and at his sides. They’re sweaty.
Katsuki tenses up when he feels hands at his hips. “Wait,” he protests, sitting up on his elbows to look at Deku. Deku stops and sits up. He observes Katsuki's discomfort and grabs a pillow from the other side of the bed. He reaches and stuffs it behind Katsuki's head.
Katsuki frowns at him, narrowing his eyes. “Kacchan?” Deku asks, smiling slightly at Katsuki's disconcerted expression.
“What is this? What are we doing right now?” Katsuki asks. He meant to add agitation to his voice, but really, he just sounded nervous. He cursed himself silently.
Deku watches him for a moment with a soft expression. He reaches to caress Kacchan's face, pausing briefly before making contact with his skin. Katsuki stares back at him and furrows his brow further, feeling cornered and growing frustrated.
“I don’t know. I just-” Deku trails off, beginning to stroke Kacchan's hair. “Sometimes I just want to touch you Kacchan. Will you let me? Is it okay?”
Deku’s voice is like little windchimes in Katsuki's ears, songlike and sparkling. The tone in his voice was so certain it was unfamiliar. Katsuki exhales gruffly. He nods a bit on his pillow. Deku shakes his head. Katsuki narrows his eyes.
“Fine, whatever. Nerd.”
Deku’s eyes sparkle with delight, and Katsuki closes his eyes, trying to tamp down his growing inhibitions. He feels the tug again at his waistband, but doesn’t move this time. This time he waits to see what happens next. He feels them move down, and then feels a tug at his boxers. Again he creates no resistance, lifting his hips slightly as Deku removes them and drops them to the ground beside the bed. Katsuki shivers involuntarily, feeling the air hit his exposed body. Deku straddles him again and leans forward until he is next to Katsuki's ear.
“Are you cold?” Deku whispers.
Katsuki says nothing, just shakes his head feeling flustered. He’s actually sweating profusely. Everything was moving so quickly. Deku's hand traces along Katsuki’s thigh, eliciting a quiet moan from his lips. Deku kisses his cheek. The hand continues moving up and up until reaching its destination. Katsuki feels himself twitch, inviting Deku to continue. Deku reaches over to the nightstand to pull something out of a drawer. He drops it on the bed and continues to trace his fingers up and down Katsuki’s thighs, teasing him.
Deku leans down and Katsuki can feel Deku’s breath between his legs. Deku places a hand on one thigh and presses softly. Katsuki responds naturally and spreads his legs apart slightly. His breathing picks up, and he can feel his heart beat in his ears. Something wet touches him, and he twitches from the stimulation. Another moment passes and Katsuki begins to wriggle his hips in growing anticipation.
“Can I touch you like this?” Deku's voice asks softly, his tongue tracing up and down Katsuki's stiffened manhood. “We can stop.”
NO! Keep going I- “-S’good,” Katsuki moans affirmatively, reluctant to speak. He couldn’t. He wished Deku would stop asking him questions. If he spent any time thinking he’d realize what was happening and run away. Katsuki emptied his mind while a warmth washed over him.
Deku continues to suck Katsuki, more and more forcefully with each stroke. He places his scarred hands underneath Katsuki's bottom and greedily takes in more of him. Katsuki is at his mercy, writhing and grasping at sheets while warm waves of pleasure wash over him. The sensation picks up and grows and grows- until his back arches and his body trembles. He’d never been made to come before, and he couldn’t hold back the moan that pierced the veil of darkness they were hiding under. Katsuki flutters his eyes open, and sees Deku hovering over him, lips glistening with evidence of their deed. Katsuki looks away and covers his face, feeling exposed.
“Do you want to roll over on your stomach?”
The question sounded so innocent when uttered from Deku’s lips, Katsuki missed the subtle hunger that was just beneath his words. He didn’t think about it though, simply obeyed the request, feeling oddly malleable. Katsuki was happy to not have to make eye contact this way. He felt the weight of Deku’s body rest on top of him, his chest against Katsuki's back. A strong hand grasped a blonde head of hair, and Katsuki's face was tilted to the side so Deku could kiss him, much more passionately than before. Katsuki began to melt underneath him, overwhelmed by the sensations. “This is okay, right Kacchan?” Deku asks once again. Katsuki nods slightly, and Deku releases his grip from Katsuki’s hair.
Deku sits up, sitting on Katsuki’s thighs. Katsuki hears a ‘click’ sound, like a bottle opening. Before he can put it together, he feels a cool, wet finger at his back entrance. He flinches.
What? This is what he wants!? Katsuki clears his throat indicating his uncertainty.
“I’m sorry,” Deku apologizes. The finger vanishes. “Not okay?”
How can you ask that at a time like this?! Of course it isn’t okay! Katsuki is broken out of his reverie state with the question. “Let’s stop,” he says, regretfully.
Deku evaporates from the bed, immediately across the room gathering Katsuki's clothes. “I’m sorry, I, um, got too carried away!”
Deku is sweating bullets now wondering what exactly came over him in the darkness. Was Kacchan actually excited or was he just completely shocked. Katsuki sits up on the bed, scratching the back of his head.
“Hey. D-Izuku?” Katsuki says softly.
Deku shudders at the sound of his name on Kacchan's lips. Was he mad? Deku knew Kacchan was about to tell him how insanely uncool that was. Was he like a total pervert? Deku is mumbling to himself and when he realizes it he claps his hand over his mouth, save for that one finger. He turns shamefully in Kacchan's direction, waiting for him to continue speaking.
Kacchan reached an arm out for his clothes, covering himself with his other hand. Deku passes them immediately, tossing the pile with a bit too much force. The blonde collects the bundle in his lap. He looks away from the nervous boy, unable to make eye contact.
“I-” Kacchan can barely get the first word out before Deku cuts him off.
“KACCHAN I AM SO SORRY I HAVE NO IDEA WHAT CAME OVER ME IT’S POSSIBLE I WAS POSSESSED OR SOMETHING YOU CAN BLOW ME UP IF YOU WANT I WON’T STOP YOU I CAN’T BELIEVE-”
“SHUT YOUR DAMN MOUTH AND LET ME TALK!” Kacchan shouts at him with his usual rage. Deku found his attitude strangely comforting, and quickly followed the order. Kacchan sighs, annoyedly and continues. “It’s not that I wasn’t…enjoying it. I dunno, it happened so fast I wasn’t ready! I need to figure out more about how I feel before we...” Kacchan grumbles, dropping his eyes to the floor, struggling to face his feelings.
“Yeah okay, I completely understand, Kacchan! I’m sorry I shouldn’t have-”
“STOP APOLOGIZING! I regret nothing so you don’t either,” Kacchan says defiantly. And it was true. He wanted it all. Deku gulps down his remaining words. He had, in fact, been about to apologize again.
“S-so…you didn’t hate it?” Deku asks, face flushing. He lowers his head but brings his eyes up to meet the boy's gaze, seeking an answer on his face. Kacchan still refuses to look back at him much to Deku’s dismay.
“No. I didn’t,” Kacchan replies, unable to control the heat rising to his face. He was happy it was dark, but he still couldn’t make eye contact. “But… this stays between us, you got that? I know how you are with secrets but this is one you’ll take to the grave one way or the other, understand?” He holds up his fist to indicate what the ‘other way’ will be.
Deku relaxes, happy to know his impulsiveness hadn’t caused his friend any upset. “Deal!”
“I’m getting dressed now,” Kacchan narrates.
Kacchan doesn’t move and after a moment Deku realizes the statement was Kacchan requesting privacy. Deku smiles a bit at the reminder that Kacchan has a shy side, even considering what they had just done together. Deku stands, feeling a bit more confident and steps closer to Kacchan, who is still avoiding eye contact. Kacchan, feeling Deku’s eyes on him, refuses to give Deku the satisfaction of meeting his gaze. Deku reaches down and tucks a finger under his chin, guiding Kacchan to look up at him. Kacchan frowns as he lifts his head, and blushes as he unwillingly looks into Deku's glistening eyes. It’s unbearable, the sincerity of them, and Kacchan feels the need to avert his gaze. Deku dips his head down and tenderly kisses Kacchan on his pouting lips. The kiss is soft and sloppy, but it's so fervent that tears begin to involuntarily well up in Kacchan's eyes. He closes them, willing the tears away, but one escapes and travels down his cheek. It lands on Deku’s finger, and he pulls away at the sensation. Kacchan turns his head and angrily wipes the evidence away. Deku continues to stand over him, watching his every move too closely. Hyperobservant weirdo. Kacchan can feel Deku’s concern and knows he must offer an explanation.
“I’m fine,” Kacchan says, only barely above a whisper. “I just didn’t know how you felt. I didn’t even know how I felt.”
Deku chuckles softly above him and Kacchan snaps his head up to look at him. He thought Deku was laughing at him until he saw the tears streaming down his stupid face. He rolls his eyes. “Cut that out,” Katsuki orders, pushing the tearful boy away from him. “You look ridiculous.”
Deku laughs harder and turns around to let Kacchan get dressed. He appreciates Deku’s intuition because he would have hated to ask. Once he’s finished he clears his throat, indicating for Deku to return to the bed. Deku peeks over his shoulder and smiles. He comes to sit on the bed next to Kacchan. “So, um” he says slowly, “Whaddya wanna do now?”
The lights suddenly turn back on startling both boys. They both look at each other in full view taking in the evidence of the previous scene around them, and the chasm between them on the bed grows instantly. Deku scrambles to put the lube back into the side drawer while Kacchan uses every ounce of will at his disposal to stop his face from turning into a tomato. Failing, he stands and plans to make his escape. Deku catches his hand. Not again.
Kacchan waits briefly to see what Deku does next. To his surprise, he lets go of his hand. Kacchan turns to see Deku looking at him dejectedly. Ugh, he’s too damn cute. Kacchan rolls his eyes again, realizing that he now has a job to do. Kacchan climbs on the bed. “Get over here, nerd,” He growls at Deku, feigning irritation. Deku excitedly scrambles into Kacchan's embrace, sinking into him like a kitten. Kacchan smells Deku’s hair and his heart melts. When did he fall in love with this loser? The two faced the same direction for a moment, feeling each other's breath synchronize, Kacchan's firm chest against Deku’s back. As Deku began to fall asleep, he rolled over to face Kacchan and snuggled into his chest. He was so happy to be surrounded by the scent of the boy he loved, engulfed by his warmth.
My Kacchan, his last thought as he drifted into sleep. Kacchan's arms tighten around the green-eyed boy as he begins to drift. Like his body is afraid Deku could disappear if he lets go. Kacchan buries his cheek into Izuku’s soft hair.
Izuku.
