Work Text:
Izuku leaned back in the infirmary chair, his muscles slowly beginning to relax. The Sports Festival was over—and he’d done the best he could, after all. He had to smile at the memory of Kacchan raging over his victory. Trust Kacchan to see the cloud instead of the silver lining. And Todoroki’s slow, careful steps towards independence were everything Izuku could hope for in a silver lining, even if he wasn’t ready to use his left side in an all-out battle yet. He closed his eyes, and released a slow breath, letting the aches of his slowly-healing bones settle, muffled by the painkillers Recovery Girl had administered.
He considered moving to the infirmary bed, the cell-deep weariness catching up to him after everything, but couldn’t quite manage the energy to make it the two feet over, and just tipped his head down. No one would notice if he rested in one of the privacy-screened areas for a couple more minutes before going home.
“Midoriya?” The soft voice came from behind the privacy curtain, startling him awake. The pain killer-induced fuzziness in his limbs was more pronounced, making him feel like he was moving through honey to lift his head. The shock of being pulled from sleep made his heart beat with a small shock of adrenaline. “All Might said you were here,” Todoroki said, pushing back the curtain enough to peer around it. “How are you feeling?”
Licking his dry lips and rubbing sleep from his eyes with his good(ish) hand, Izuku smiled weakly. “As good as I can be,” he said. “Recovery Girl thinks there are bone splinters in my right arm that I need surgery to remove before she can help me heal any more. But I’m mostly just tired.” Todoroki flinched at the extent of Izuku’s injuries and Izuku tried to put up his good arm to backpedal. “I’m fine, though! You don’t have to worry—I kind of did it to myself, because I wanted to beat you really badly, and you were really cool when you were fighting back, so it’s not like I regret it or anything!”
Todoroki stepped around the curtain, tugging it closed again. His mismatched eyes were dark and concerned, eyebrows pulled together in a small frown. “You did this to yourself,” he repeated slowly, “for me. You smashed your own body and smashed my inhibitions along with them.” He took another measured step towards Izuku, looking him up and down as though searching for something. “I want to repay you for that. Even if I couldn’t keep fighting that way in my last battle.” He trailed off, holding his left hand up, a small flame flickering momentarily and then dying out.
Another measured step and his legs almost bumped Izuku’s knees. Izuku wriggled upright, the last remnants of sleep sliding away, and smiled up at Todoroki. “You don’t have to do anything, Todoroki-kun. I meant what I said and,” he laughed, going a little warm around the ears, “you still blew me away, even though I was trying my hardest to beat you.”
Even though he nodded thoughtfully, Todoroki didn’t back up and Izuku wiggled in his seat, uncomfortable. There was something intense about Todoroki’s presence, like heavy air pressure before an avalanche. “I mean,” Izuku said, trying to laugh it off, “you can buy me lunch in the cafeteria when they have yakisoba pan again. Or, uhm. Class notes would be nice. I can’t write well like this” He watched the way Todoroki’s eyes narrowed, and his lips twitched down. In the back of his mind, Izuku felt himself starting to collate commentary for his hero notebook. There was more to Todoroki than he’d expected, so he’d have to add a section on his mental state.
“That’s not what I meant,” Todoroki said after a long moment. Izuku’s throat closed, although he couldn’t say way. Resting one hand on the back of Izuku’s chair, Todoroki leaned in and pressed a kiss to Izuku’s lips. They were smooth, soft and warm, and so unexpected that Izuku opened his mouth in confusion. Todoroki took it as an invitation.
The kiss would have been a nice first kiss, all things considered—slow, careful, all gentle nips and the wet slide of tongue. Izuku pulled his head back, gasping. “To-todoroki-kun,” was the only thing he could think of to say, his less-injured arm pushing at Todoroki’s shoulder. “What are you--?”
It didn’t dissuade him. Todoroki pressed a line of kisses down Izuku’s bare neck and shoulder, only stopping when he got to the neat rows of bandages holding Izuku together. “Thanking you,” he said simply, as though it was obvious. “It’s my fault you were hurt, so I’ll make it up to you.”
“No,” Izuku protested, although it came out as a gasp when Todoroki sunk his teeth in a slightly-too-rough bite at the juncture of neck and shoulder, and sucked. “I d-don’t need you to do anything like tha--” The words were cut off with another whimpered gasp as Todoroki drew his hand down Izuku’s chest, carefully avoiding the sling that held his injured arm. The slender fingers were cool, and callused from fighting, sending shivers down Izuku’s spine and sparks of confused pleasure across his nerves. He cleared his throat, and tried to push his chair back, but Todoroki was already crowding him, hands alternately warm and cool on his sore muscles and the lacerations Recovery Girl had yet to take care of it. Izuku wasn’t a masochist by any means, but the medication-dulled pain added a weirdly pleasant frisson to the sensations. “Todoroki-kun,” he started again, but Todoroki took the opportunity to kiss him again, deeper this time, and Izuku opened his mouth to it, letting that hot mouth ravage him. He whined softly, trying to push Todoroki away, but his arm had little strength in it and his fingers tangled in the fabric of Todoroki’s top instead.
When Todoroki stood up again, Izuku licked his lips, trying to calm his racing heart. He didn’t know what to think, how to feel about being kissed—his first kiss!—by Todoroki for a reason like that. He drew a shaky breath and shook his head. “That really wasn’t necessary,” he said again.
“But I’m not done,” Todoroki said, the words plain and blunt. “It takes more than that to thank you.” Izuku barely got a moment to think before Todoroki was falling gracefully to his knees, settling himself between Izuku’s legs, careful not to jostle him too much. “I’m going to replace the pain with pleasure.” The warmth of his left hand running up Izuku’s bare calf made Izuku gasp and try to protest again. It was like a heating pad against the aching muscles, and felt good, but that wasn’t what Todoroki was really trying to do. He spread Izuku’s legs, ignoring confused protests, and stroked the thick, fabric-covered thighs when Izuku’s words were interrupted by low hisses of pain from being moved around.
“What are you doing?” Izuku tried to push Todoroki away again, this time with even less leverage and success. “I don’t—you really don’t have to—Todoroki-kun, please!”
Todoroki traced his warm hand up under the rolled-up fabric of Izuku’s pants, blunt fingernails scraping almost delicately at the sensitive skin of his inner thigh and Izuku shoved at Todoroki again, caught between the pleasure of the sensation and the need for Todoroki to not being doing this, not now, not here, not like this, with Izuku barely able to move and Todoroki doing it out of obligation. He whined, trying to find the right words to make Todoroki stop.
It wasn’t until the cooler hand wrapped around the slowly hardening bulge between his legs that Izuku knew he was really in trouble. Todoroki squeezed it gently, rubbing his fingers over the length as though he knew what he was doing, working Izuku until he was biting his lip and tensed to keep from squirming.
“It feels good, right?” Todoroki said softly, looking up at Izuku from under his bangs with the softest, most hopeful expression Izuku had ever seen from him. It made Izuku want to sob because yes, it felt so good, and he wanted Todoroki to stop so badly. “You don’t have to hold it in, if you want to moan. I want you to enjoy it.”
He squeezed again, thumb pressing to the tip of Izuku cock, and Izuku choked back a sound. The word on the tip of Izuku’s tongue was “please”, and he knew that Todoroki thought it meant more, please when what he wanted to beg was please, stop. Why didn’t Todoroki understand? Why was he looking up with that encouraging smile? Why was he being so sweet, when Izuku was asking him to stop?
Todoroki didn’t even look away from Izuku’s face as he unzipped the pants, expression on his face the most tender Izuku had ever experienced. His fingers were chilly as he freed Izuku’s cock, and brushed it in slow, teasing motions. In the back of his mind, where he was keeping a running tally of this whole situation far away from the emotions shattering his heart, Izuku noted down the question of where Todoroki had learned how to do this so well. He knew how long to let his cold hand linger, gently smearing the precum that Izuku was all but drooling, using it as lube when he stroked suddenly, hard and fast. “Nnn--no,” Izuku whined, the muscles in his thighs complaining too as his hips arched without his conscious consent.
“Don’t worry,” Todoroki assured him, “I know what I’m doing.” And then the cool fingers wrapped like a ring around the base of Izuku’s dick, and the rest was engulfed in wet heat as Todoroki took him all the way into his mouth. Izuku couldn’t help the sound he made, somewhere between a sob and a yell, hips jerking up, although he tried pushing Todoroki away again to no avail. Todoroki wasn’t lying, either. He swallowed Izuku all the way down without a problem, letting Izuku’s cock bump the back of his throat. His cheeks hollowed and Izuku sobbed again, hips twitching at the sudden intense suction. Realizing that it must be overwhelming, Todoroki pulled back, licking a long, slow stripe up the underside of Izuku’s dick, pressing his tongue flat against the sensitive vein. His eyes fluttered open again, looking up at Izuku as though looking for praise, making sure it was good.
Izuku wished he could cover his burning face with his hands, hide from Todoroki’s serene gaze. All he could think of was to squeeze his eyes shut, but that-- it made everything ten times more intense, the cool hand squeezing and rubbing his balls, the gentle, relentless sucking, and occasional grazes of Todoroki’s tongue. Izuku had nothing to hold onto with his eyes shut like that, nothing but the way Todoroki was making his body feel. He opened his eyes again, reaching out to try and push him off, but ending up just fisting his hand in Todoroki’s red locks. “Please,” he said again, trying to make his mouth work properly. “Not like-- please!”
“Aah?” Todoroki pulled back, mouth hanging open. His lips were puffy and spit-slick, and quirked up into the closest to a happy smile Izuku had seen. “Not like that?” His fingers still stroked Izuku’s balls, sliding in quick little strokes down his perineum, and Izuku realized with horror that his hips were meeting those tiny thrusts. Todoroki licked his lips, and brushed hair from his face with his free hand. “I see. You want more of that. Don’t worry, Midoriya-kun, I know how to do that to make you feel good too. I want to make sure to thank you properly.” He sat back on his heels, releasing Izuku’s cock.
Izuku couldn’t stop a low sound at the sudden loss of sensation, a full body shiver rolling through him. “N-no, Todoroki-kun, I don’t think you un-understand,” he stammered. He couldn’t fight back-- physically he could barely walk, much less move Todoroki around, and Todoroki was doing this to… to thank him. He couldn’t hurt Todoroki by rejecting him like this. Izuku chewed his lower lip, trying to ignore the familiar tightness in his chest and heat behind his eyes.
Oblivious to Izuku’s turmoil, Todoroki brought his fingers to his lips and sucked on them, licking them, lazily at first but sloppily. His eyes were half-closed in enjoyment, and Izuku watched in horrified desire, mentally matching the gestures to things Todoroki had done to him that he hadn’t been able to see before. It made Izuku’s dick tighten as he tried not to think about Todoroki’s mouth and tongue wrapping around him again. Even when he closed his eyes, the sounds were loud and too obvious.
When the sounds stopped, Izuku risked opening his eyes, and realized why Todoroki had pulled away like that, so suddenly. The cool hand was back on him, tugging his pants down to his knees, stroking his hips and thighs, and brushing along his dick in careful strokes. The other hand, the hand that Todoroki had so happily sucked and licked, slipped between Izuku’s legs to press against his hole. “Ffu-- nno, Todoro--ki-kun, please!” He gasped, but that was all he could do before Todoroki pressed a finger inside him, and all the air seemed to leave his lungs. Just the one finger and it felt big, like Izuku couldn’t breathe around it.
“It’s easier if you relax,” Todoroki said gently, rocking the finger back and forth. “Trust me, it will feel good soon.” He leaned down, wrapping his mouth around Izuku again, sucking in time with the short thrusts of his finger. Izuku made a low, sharp sound, feeling like he was breaking apart, helpless. His good hand clutched at Todoroki’s hair, and he whimpered pleas, begging in short incoherent bursts for Todoroki to stop. Todoroki didn’t stop, he swallowed around Izuku’s dick, all suction and heat. Before Izuku could even find a way to breathe, there was a second finger in his ass, rocking him, stretching him out. Todoroki crooked his slender fingers, making room for a third, and pressed in more deeply than Izuku could ever remember anything being inside of him.
Todoroki hummed around Izuku’s dick, and Izuku could barely keep from screaming, his eyes squeezing shut. He knew what was coming, his legs spread by Todoroki’s body, his ass spread by those warm, clever, friendly fingers. Tears began to roll down Izuku’s face. He couldn’t stop them, not when he was helpless to stop one of his best friends from taking him apart piece by piece. “To-todoroki-kun,” he whispered, voice choked and hoarse. Todoroki hummed again, the vibration running up and down his body like electric shocks, and then Todoroki pressed a spot inside of him that made him arch and scream.
Izuku cried, his fingers twisting in Todoroki’s hair as his hips thrust desperately. Todoroki, for his part, seemed to take it in stride, never pulling off Izuku’s cock, and swallowing everything Izuku gave him, and milking him from the inside out until Izuku couldn’t do anything but weep and tremble.
When Todoroki finally pulled away again, he licked his lips clean of the last remnants of Izuku’s cum, watching Izuku shudder beneath him. He rocked to his feet easily, wiping his fingers clean on the bed’s sheet. “Midoriya-kun,” he said softly, his voice barely above a whisper, “you were so soft and wonderful inside. You did so much better than I did my first time.” He wrapped his arms around Izuku, nuzzling his neck where he’d left a slowly purpling mark. “I’m glad I could make it so good for you.” He kissed up Izuku’s neck, the overstimulation, and the desperate desire for Todoroki to finish and leave, making Izuku moan and shudder.
Fat tears rolled down Izuku’s cheeks, and even if his arms had been working properly, Izuku wasn’t sure he’d have been able to move to wipe them away. Instead he tilted his head away when Todoroki kissed away the tears, tongue darting out to lick away a drop. “I-I-- Todoroki-kun, I--” he stammered.
With a thoughtful sound, Todoroki stepped back and eased Izuku into his arms, petting his hair. Izuku couldn’t stop shaking and crying, finally pressing his face against Todoroki’s shirt to hide. “You probably need to get some rest,” Todoroki said, smoothly carrying Izuku the few steps to the infirmary bed and setting him down. “I’m glad you enjoyed it. You,” Todoroki blushed pink and looked away, “you know you can ask me for anything. At any time.”
Izuku sucked into a shaky breath, trying to ignore the tears still rolling down his cheeks. He nodded with a jerky motion, using his good hand to tug at the sheets. “I-I know, Todoroki-kun. So you, you should go home and g-get some rest yourself.”
Todoroki ran a hand through Izuku’s hair in a tender motion and smiled again. “I’ll see you in class tomorrow.”
After the infirmary door clicked shut, and Izuku was sure Todoroki had left for good, he curled himself into a ball and let himself shatter.
