Notes Thanks for @joestar_cock and @enjisbarathighs for all the ideas. Go check out their twitters and stuff. Enji wiped away the blood dripping from his lip, smirking as he once again lit his palms on fire. His sworn rival stood across from him with the same wild smile, as usual, his body hunched over and his blond hair a mess. He clenched his fists when he noticed Yagi only had a few scorch marks He bitterly spits out blood, the red painting the training rooms floor. He threw out his wrist, a flame flying from his palm, aimed at Yagi only for it to be dodged. His jaw clenched when he saw a fluff a blond whirl at him, and he quickly jumped out of the way, sending another blast of heat towards the figure. He instantly smelled the scent of burning skin and hair, a smirk of triumph lifting his lips as he saw Yagi skid to a stop clutching his arm. “Gonna have to be faster than that Toshinori.” Enji only got a wide grin in return as he saw the patterns paint Yagi’s body again. He barely saw when the ripped body sprinted towards him, and he didn't expect to be hit right on. He blinked as the pain barely registered, his body slamming into the ground with Yagi’s on top of him. Enji saw the wide grin and he growled, fire igniting inside him at the mere thought of Yagi winning again. “Was I fast enough this time, Enji?” Enji just clicked his tongue at the sentence of innocence as the blond locks fell into his eyes. He twisted his head away, unable to cross his arms due to them being pinned by the-stronger-Yagi. He heard boisterous laughter above him as he felt the brush of hair against his cheeks. He looked up only to see a face closer than it should be. Enji gulped, averting his eyes, but calloused fingers gripped his chin, tugging his head towards the smiling Yagi. Enji huffed, jerking his hips to get Yagi off, but he froze once he heard a soft moan. He glared up at the blond teen, seeing the endearing eyes soften into a more… admired? Look. “Enji… you're so goddamn beautiful…” he felt the minty breath spread across his face as lips almost brushed his. Enji was frozen, his heart stuttering in his chest as his breath hitched. He tried to move his head, but Yagi kept a strong grip on his face. “I-i really wanna kiss you… Can I?” Yagi asked, gulping as he stared at the gorgeous teen beneath him. A fire burned within him as he glanced down at those soft-looking pink lips. He licked his own lips, feeling heat erupt deep in his body. His ever-growing crush on Enji was present as he smiled softly down at the shocked teen. Yagi rolled his hips, biting his lip when he felt the hardening member under his ass. He watched Enji’s expression morph into a panic, and Yagi quickly grabbed his other hand before a fist engulfed in flames hit his face. He looked at those soft lips, and even without the consent, he smashed his own into Enji’s. The blond haired teen moaned into the soft lips, his eyes fluttering closed as he moved his lips against the frozen Enji. Enji froze, shocked by the pressure of lips on his own. He looked up at the face above his, seeing the blissful look and felt the brush of blond eyelashes against his cheeks. His own eyes closed as he slowly melted into the soft kiss, his body relaxing. A tongue brushed across the seam of his lips, alerting him and making his eyes snap open. He quickly snapped out of it, the grip around his wrist loosened as he ignited his palm. Anger filled Enji as his yell was muffled by the kiss, sending a flaming punch towards Yagi. The effect was immediate as the young teen was sent flying off him. He glared, his eyes burning with hatred as he stared at the offending man. Yagi wiped his lip of the blood as he stared at Enji’s enraged filled eyes. He gulped, letting One For All charge through his body as he sprinted away, the ground cracking at the force he used. But Yagi’s luck was out. He tripped over a loose pebble, his feet flying from underneath him. He fell face first into the hard ground, yelping in pain as he felt heat scorch his ass. He turned his head only to see a glimpse of Enji’s red face as he stormed out of the training arena. “Fuck you, Toshinori Yagi!” Enji screamed, slamming the door shut as Yagi looked at his retreating form in a daze. That kiss… was it Enji’s first?     ******     Enji stormed through the lingering students and teachers, glaring at anyone who questioned his red face. He dazedly reached for his lips, remembering the soft push of Yagi’s against his. He shook his head, fire igniting in his palms as he tried to call the fury boiling inside him. T-that was his… first kiss… and Yagi took it... “Fuck, fuck, fuck, fuck!” he growled, slamming his fist into the wall. Scorch marks singed the wall, painting it black as he grumbled and grunted. He paces to his dorm room, opening the door and face planting on his bed. Enji turned on his side, clutching his flame-patterned pillow close to his chest as he thought of the events that just happened. His face flushed at the thought of Yagi’s lips against his, claiming his first kiss as his. Unable to bear the thought of it, Enji buried himself into bed, clutching the pillow as he closed his eyes. Stop thinking about it, stop it, stop, stop, stop, STOP!! Knocking erupted on the door, his eyes snapping open as he looked over at the door. Yagi sighed softly, resting his head against the door as guilt consumed him. He really wanted Enji as his, and he did know it was going to be difficult with Enji’s… eccentric personality. He licked his lips nervously, still able to taste the tang of blood and the heavenly taste of Enji on his lips. His hands shook as he knocked again, hoping Enji would reply, or say anything, to him. Yagi distracted himself by rocking on his heels, scouting the hallway for anything until he noticed the scorch marks painting the once blue wall. He winced, gently reaching a hand to rub his throbbing ass. “En-Todoroki, can I come in?” Yagi tentatively asked, knocking again as he set his hand on the hot doorknob. Touching the metal almost burned his hands at the heat radiating from it. Damn, Enji must be pissed. He gently turned the knob, hearing a click as it slowly swung open. He stepped in, licking his lips as his hands fumbled by his side. Yagi looked at the bed seeing a mass huddling underneath the pile of blankets and pillows. “T-todoroki…?” Yagi asked again, nervously wiping his hands on his uniform pants. He had to change because his ass cheeks were exposed to the world in his training uniform. “Go the fuck away before I singe your ass again, Toshinori!” the shout was muffled by the ton of blankets piled on top of Enji. He cursed himself for forgetting to lock the door as he heard footsteps step closer to him. He hissed, shooting out a fist when he felt the heat radiating off Yagi, through the blankets and all. Before he could ignite his hand, a strong grip locked around his wrist and yanked him from underneath the blanket. Enji yelled curses, lighting his other hand on fire as he went to punch Yagi but once again, his hand was caught by the other male. He glared up at the handsome blond who stared at him with hard eyes. “Todoroki, stop it,” He commanded, setting his lips in a thin line. Enji glared, spitting at the blond with a snarl, bucking his body around and twisting, hoping to get out of the hold. He heard a soft growl as he felt a body slam on top of his, forcing him to stop all movement. Enji glared up at Yagi, teeth bared as he still tried to move. He saw the blue eyes glow as his skin lit up with his quirk. Enji cursed loudly, feeling the power radiate off Yagi’s body. “Enji, stop being a fucking brat.” He froze at those words, unable to take in that Yagi, the fucking goody-two-shoes, just cursed. He blinked slowly, looking into the glowing blue eyes that seemed to suck in his very soul as he stilled. Enji saw the victorious smirk spread across Yagi’s full, pink lips, and he immediately wanted to smack it off his face. It annoyed him immensely when Yagi felt high and mighty when he made him submit. “Good boy.” Heat spread across Enji’s cheeks as he heard the praise, lower body wiggling as warmth spread through his body. Good boy? Why did it feel so good to hear that? And hear it from Yagi no less. “See, all you have to do is listen to me for five minutes and I'll leave you alone. Okay? Can you do that for me, Enji?” Yagi asked softly, letting go of one of the hands, reaching up to stroke the soft cheek. Enji grumbled, ripping his other arm from his grip as he grumbled softly. He crossed his arms over his chest, glaring up at Yagi who smiled brightly down at him. He hesitantly nodded his head, seeing the smile turn into a big grin that stretched across the entirety of Yagi’s face. He looks like an idiot smiling so wide because I agreed to listen to him… a cute idiot though… He flushed at his own thoughts, trying to hide it with a frown. But it was too late, Yagi had already seen the red flush spread over his cheeks and ears, grinning impossibly wider. “Listen, I have been in love you for a while now Enji. At first, it wasn't like that. I just loved the idea of having a strong rival like you, but slowly I fell in love with the idea of you. You, with your cute, arrogant smirk, your beautiful eyes, and body, and, I'm surprised to say this, but your explosive personality was like no other I've seen. And I fell in love with all of your flaws and your beauty,” Yagi listed lovingly, kissing the flushed cheeks. Enji felt his chest warm his heart pounding against his chest. He was shocked that the pure, and heart-throb Yagi fell in love with him. Stunned didn't even explain his expression “O-oh…” really? That was all he had to say to the heartfelt confession? It's difficult to see why Yagi fell in love with this idiot. Yagi laughed, falling onto Enji, his lips peppering kisses all over his face. The redhead grumbled with a bright red flush on his cheeks, trying to weakly push away Yagi, secretly in love with the feel of his lips on his face. “You're so fucking cute!!!” Yagi squealed, his cheeks a soft pink as he grinned, cuddling into the strong chest. Enji grunted, hesitantly wrapping his arms around the laters waist. They cuddled for a minute before Yagi gently pressed his lips against Enji’s. Enji’s eyes fluttered shut, feeling passion and love in Yagi’s kiss, feelings things he never has with another person. Yagi hummed into the kiss, setting his hands on the redhead's waist. They slowly moved, exploring each other's bodies. Enji, very hesitant in his every action, and Yagi, bold with every caress. They parted their lips for air, briefly opening their eyes to stare into each other's eyes, red clashing against bright blue. Their lips met again, Yagi intent on tasting Enji’s lips again. He swiped his tongue on the seam of those thick lips, moaning at the taste of pure Enji as he tried to force his way into his mouth. Enji sputtered, pushing away at Yagi’s chest as he wiped his mouth with his other hand. “W-why the hell would you do that, fucking idiot?!” he shouted in embarrassment, his face flushed a bright red. Yagi giggled, fucking giggled, at him with a soft smile as he gently kissed his cheeks. “I was gonna French kiss you, Enji. Did you not realize that?” the cute blond tilted his head to the side, saying French kiss in English. Fuck me, he sounds hot when he speaks English… He blushed a brighter red, matching the color of his flames at this point as he turned his head to the side. A hand covered Enji’s face as he tried to hide his embarrassment from Yagi, his inexperience obvious. “O-oh, I-I forgot about that!” Enji shouted, knowing that he didn't believe his own lie and he's not fooling anyone. Yagi only laughed, smiling at the adorable actions of his cute, hopefully, boyfriend. He gently ran his hands up to caress at the soft hair, tussling the hairstyle Enji probably spent longer than necessary trying to perfect. He got his answer when a growl was heard and a punch was sent to his chest. “You're not fooling me Enji. You've never had a French kiss before, and I know you've never had a physical relationship. Don't lie to me…” Yagi whispered, ghosting his lips over Enji’s. He moved the hand covering his boyfriend's face, smiling at him. His tongue swiped across the bottom lip, then he gently bit it, tugging the full bottom lip. Enji blinked, his eyes slowly fluttering shut, his back arching against his will, a soft moan leaving his mouth. He clenched at the bed sheets, heat pulsing throughout his body as foreign sensations filled him. “Mmm…” He moaned again as a tongue pushed past his lips. His hands reached up to tug at the soft blond locks, crying out at the feel of strong hands running down his body. “Enji…” the redhead felt the whisper against his lips when they parted, only for them to be taken again. His fingers pulled at the hair, drawing out a grunt from Yagi, his hips stuttering against Enji’s. They both gasped in pleasure as Yagi continued to roll his hips into Enji’s. Heat shot to Enji’s crotch causing a soft gasp to escape his lips. He couldn't help but jerk his hips into the air, moaning at the pleasurable sparks radiating from the touching of their dicks. “T-toshinori… fuck…” he panted, his chest raising more erratically as they continued to indulge in their pleasures, drowning in the sensation of each other. And with the lost control over their movements came the lost control of their Quirks. Heat pulsed off Enji’s hands fisted in Yagi’s hair, only to be ripped away by the blond who feared for his head. Using too much power when he pinned Enji’s hands down. He chuckled softly, stopping his hips as he breathed in, trying to relax. Enji was too gone to realize what was happening, his palms lighting on fire as he let himself be immersed in bliss. He moaned again, biting his bottom lip as he continued to grind into Yagi. The blond grinned, seeing the redhead drowning in pleasure. He wanted to see the hero-in-training to fall apart completely. Yagi slotted his thigh between Enji’s, taken away by the absolutely gorgeous reaction. Enji’s back arched off the bed, his hips furiously grinding on his thigh. His mouth dropped open as he panted heavily, chest heaving as his head snapped back. A loud moan escaped his parted lips, the pink lips glistening. Warmth spread throughout his body as his muscles tensed. Cum squirted from his tip, soaking his pants and boxers. A stain making itself known as hot liquid continued to spew from Enji. His back arched high off the bed and a loud cry leaving his lips. Fire licked at his skin as control over his quirk was lost, cum still soaking the pants. He emptied his balls as he fell back to the bed a panting mess. His vision was white with pleasure, hips twitching and body pulsing with energy. He panted heavily, slowly opening his eyes to see a dazed expression on Yagi’s face. The sight of Enji cumming had Yagi hard as a rock, pre-cum staining his jeans. He hadn't had time to slip on a new pair of boxers when he was running after Enji. He licked his lips like a starved man, drool piling on his mouth as he yanked off Enji’s pants. “W-what… the fuck?!” he heard the yelp but ignored it as he revealed the mess Enji had made. A moan, so full of lust and desire, had escaped Yagi at the sight of cum covering the fabric, sticking in the red hairs at the base of the softening cock, and the cum covered cock was too much for him. Yagi dived in, his tongue lapping and slurping up the warm cum, moaning at the taste. He stared up at Enji with half-lidded eyes, lust clouding his eyes. His cock rubbed lazily against Enji’s calf, mouth sucking at the sensitive cock. Enji’s leg twitched up as he clenched his thighs around Yagi’s head, hand yanking at the blond strands. His body trembled as sensitivity shook his entire body, mouth spilling cries and whimpers. The blond couldn't help but sniff the musk floating into his nose, the smell of Enji absolutely divine. He moaned softly, laving his tongue over the sensitive skin. “T-toshi-nori…” Enji gasped, hips bucking away from the touch. His body was over stimulated, forcing another spurt of cum out of his cock. He bit the inside of his cheek to contain the screech that wanted to escape him. They were still in the dorms after all. “Fu-ck...you smell so good, Enji. So fucking good…” Yagi moaned, digging his nose into Enji’s crotch. He inhaled deeply, pulling away as he felt the desperate need to be inside Enji. A growl erupted from his chest as he crawled up the expanse of muscle, licking the sweat-slick skin as he went. Enji cursed when the warm tongue wiped over his sensitive nipples. His body arched into the sensation, Yagi taking great pleasure in his reactions. “You're so fucking hot…” Yagi groaned against his chest, cupping the thick pecs in his hands, squeezing the piece of bulging muscle. Enji couldn't hold in his cries, body heating up and burning in reaction to Yagi’s ministrations. Yagi stopped-remembering the whimper Enji made- straddling Enji’s lap as he yanked off his shirt, his face painted a bright red, sweat trickling down his cheeks. His chest heaved with his pants, his fingers fumbling with his jeans as he desperately unbuttoned them and chucked them to the floor. Naked bodies pressed against each other, hands moving in fervor. Enji hesitantly pressed his hands into Yagi’s strong back, feeling the muscles bunch underneath his fingertips. He buried his face in the tensed neck that was thrown back, biting into the salty skin to stop his sounds. Yagi cried out when their hips ground against each other, cocks slick with pre- cum as they rubbed against each other. He reached for Enji’s nightstand, grabbing a bottle of lotion as he pulled the young man from his shoulder. “You're so beautiful…” he breathed at the sight of Enji’s half-lidded eyes and parted pink lips, his cheeks painted a bright red. Yagi kissed his parted mouth, slipping his tongue in and tangling it with Enji’s. They both let out soft moans, Yagi swiftly slicking his fingers with the lotion, parting the redhead's legs. He knelt between them, kissing Enji to distract him from his next action. Cold fingers slipped between Enji’s crack, pressing against his hole. His eyes snapped open, palms heating up as he jumped away from the intruding appendage. Yagi gently hushed the soft whimpers that escaped Enji, watching those soft cheeks flush a bright red and those swollen red lips parted with soft pants. Nails dug into his back as he looked at the redhead with a loving look, running his hand up and down the tensed abs. “T-toshi…” Yagi couldn't help but capture those lips in a soft kiss, slowing the pace a little as he massaged the tensed entrance with his middle finger. Enji melted into the kiss, his body relaxing as he kissed back the blond. “It's alright baby, you just need to trust me. Can you do that for me, baby? Can you trust me?” Yagi hummed softly, their lips resting against each other, their noses bumping against each other. Enji gulped, nerves shaking his body as he nodded his head, unable to stop the soft smile that made its way on his face. It was out of character for him, but Yagi made him feel things… things he's never experienced before. “You're so good for me, baby. You're such a good boy for me,” Yagi whispered, grinning against the smiling lips. Enji’s body jerked at the praise, his abdomen clenched and tensed, cock jerking on his stomach, and hole clenching around the fingertip. He closed his eyes, biting his lip and hoping Yagi hadn't seen his body react to the praise. “Oh. So you like me calling you a good boy, huh Enji? You like knowing how good you are for me? How beautiful you look spread out underneath me?” Enji bit his bottom lip, looking away as a hot flush took over his cheeks. He couldn't help the swell in his chest at the thought of being good, especially for Yagi. The praise consumed his being as he wiggled on the bed, hands gripping the flametardent sheets. A soft whine left his mouth when the finger pressed in deeper, his body squirming on the bed as the finger massaged his insides. It was a weird sensation, the feeling of being filled. Yagi grinned at him, gently kissing away any discomfort as he slipped in another finger, curling them and pressing against the firm bump. He knew that Enji would explode. The reaction was instantaneous. Enji felt heat rush through his body, flames igniting his skin as his back arched off the bed. Finger tangled in the sheets, muscles tensed, and thighs quivering with the hold on his release by Yagi. A firm fist clamped over his erection, chest heaving as he whined and moaned in discomfort, hips twitching into Yagi’s grip. “T-toshi… nori… you fucking asshole….” Enji gasped, head thrown back as sweat trickled down his heated body. Some of the sweat evaporated at the intensity of the heat radiating off his body. Yagi couldn't help the gulp of saliva as he saw the way Enji lost control of his body. The way his muscles trembled and shook as he desperately clutched to the sheets. He couldn't take it anymore! Fingers were yanked out the small puckered hole, the muscles clenching around thin air as the intrusion left. Enji gasped, body rocking on the bed as something hot and wet touched at his hole. He looked down, moaning as it breached past the ring of muscle. Yagi panted heavily, biting his lip to make sure he doesn't just ram in Enji, making sure to take his time. His heart clenched in his chest, skipping a beat at the look of awe Enji held in his eyes. Teeth dug into his bottom lip, threatening to break the skin as tears welled in his eyes. His lips stretched into a smile, unbelieving that this was actually happening. The many daydreams and sleepless nights are becoming a reality. A single tear rolled down his cheeks, pressing his hips in more. Enji watched the pathetic Yagi tear up with a big smile. He rolled his eyes, knowing the idiot couldn't help himself. The edges of his lips curled up as he sat up, wrapping his arms around Yagi. A hand pressed against the blond’s head, pressing his head into Enji’s neck. A stuttering breath left Yagi as he slowly sunk into the tight heat. The redhead cried out sharply, his head was thrown back at the unexpected object entering him. “F-fuck…” Enji breathed, neck straining as he gripped at Yagi’s strong back. A strangled moan left the blond as the muscles squeezed around his cock, slick with the lotion they used. The redhead couldn't help the heavy pants leaving his mouth as a shining sensation started up in his lower back. He gritted his teeth, stopping himself from making a noise of pain. He's training to be the number 1 hero, if he can't take this pain, then why is he even fucking trying?. It'd be pathetic of him if he were to break to the pain. “Oh my god… Enji… you're so tight!” Yagi breathed, the heat and squeeze around his cock was almost enough to throw him over the edge. His heart warmed when Enji clung tighter to him, gently rocking his hips into Enji’s as their skin met. “Fuck… I'm all in…” he moaned, swirling his hips until heated hands burned his skin. Yagi yelped, tensing and wincing at the heat, stopping all movement. Enji let out a sigh, body slowly relaxing again as the pain started to numb, very slowly. “J-just… fuck, just wait a second Toshinori. You're too goddamn eager,” Enji scolded, smacking his hand harshly on the bareback. Red blossomed on Yagi’s back in the shape of a handprint, and his wince of pain said that he hurt a lot. “Okay… sorry, I'm just- I'm just really happy that you accepted me…” Enji sneered, trying to hide the smile that wants to creep up his face. Yagi grinned at him, his face flushing a soft pink as he buried himself in Enji’s neck. “You're really, really, really cute!” he squealed, squishing Enji in his arms as a grin overtook his features. His movement caused his cock to press against that one spot, sending a shock of pleasure up Enji’s spine. The pleasure being unexpected, the redhead moaned loudly, eyes squeezing shut. Yagi perked up, gently rotating his hips with a smirk when the man underneath him continued to let loose his sounds. “Fuck! Holy shit!” Enji couldn't stop the sounds escaping his throat, moan after moan leaving his swollen lips. The blond sat up, causing him to scowl, digging his nails into the tan skin. The smirk on those pink lips sent an arrow into his heart, causing it to skip a beat. I don't fucking like that dumbass blond… with his dumb cute smile and that cute little smirk… oh shit. Hips retracted, only to meet back together with a loud smack. Enji cries out, nails clawing into Yagi’s back as he set a brutal pace. Skin slapping against each other, loud noises leaving Enji as he was thrown into a high off of pleasure. “F-fuck! Toshinori!” he yelled, almost screaming as his head fell back. His entire body started to heat up, small bursts of flames erupting on his skin as he tried to reign control of his Quirk. Yagi groaned, moaning loudly as he chased his release, grinding his hips. Tan skin beginning to glow with the activation of One for All, Yagi’s grip and thrusts getting harsher. The two teens, unable to control their Quirks, quickly chasing after their release, gripping onto each other desperately. “E-enji… fuck… I-i can't hold on for m-much longer…” Yagi panted, finally reigning control of his Quirk a bit. Enji’s response was a loud moan a desperate nod of the head. The blind reached down and gripped the throbbing erection, jerking it off to the pace of his erratic thrusts. Sweat fell down their muscled bodies, training having hardened and developed those muscles that shook with pleasure. “Oh god, shit…” Enji cried, his back arching off the bed as heat pooled in his crotch, balls tightening as he shot his release. An explosion of pleasure erupted in his body, muscle tensing and clenching down harshly on Yagi. His body thrashed and trembled on the bed, fingers clawing at the strong back. He screamed his release, eyes screwing shut as cum splashed into his chest, dribbling down his cock and around Yagi’s fist. Yagi moaned loudly, his body tensing as he thrust erratically into Enji’s body, uncaring of anything except reaching his own release. Hot fun tumbled out of his cock, shooting deep into Enji as he cried out. He stopped all movement to spill his cum, his body hunched over as Enji fell to the bed spent. The blond gave some experimental thrusts towards the end of his release, soft moans escaping him and Enji, too sensitive to start again so soon. Yagi fell to the bed with a wide grin, his blue eyes filled with joy as he hugged Enji close to him. He paid no mind to the drying cum on the redhead's chest as they cuddled on the sheets. Enji reluctantly wrapped his arms around the snuggling blond, rolling his eyes with a soft smile. He ran his fingers through the blond locks as exhaustion took over his body. Red eyes slowly drooping as Yagi gently kissed his neck, rubbing circles on his lower back. “I love you, Enji…” he whispered as sleep took over their bodies.
