Work Text:
“Deku, wait!” The pro-hero Uravity soared overhead, trying to keep the messy green hair in her view.
“I can swim, and we can’t wait,” her friend called up to her. She sighed and with a burst of power, she accelerated forward.
“Deku, don’t! Froppy will be along in a moment, and she’s a better swimmer than you!”
“He’s getting away, Uravity!” Uravity winced as the pro hero launched himself over the edge and into the water below, where the villain had disappeared under the waves.
“Damn it,” she muttered angrily, as she fumbled for her radio. “Attention all units, heroes in pursuit of Villain, last seen jumping into the sea. Pro Hero Deku has followed, requesting back up. Froppy, are you in route?”
“Copy that, Uravity, I’m five minutes away,” she heard her friend’s voice respond. Five minutes. Uravity scanned the water anxiously, searching for a sign of that messy green hair. Her friend was a great hero but he was also reckless, impulsive, and always willing to sacrifice himself in an instant.
“Uravity, do you have Hero Deku in your sight?” She winced again, not wanting to answer her mentor.
“Negative, ma’am. He’s gone under the water and I… I don’t see him.” She cursed as her voice shook. If Deku’s boyfriend was listening to the radio, he would surely be frantic.
It was Todoroki’s day off, she reminded herself. He shouldn’t be anywhere near the agency.
“Hawks, prepare to extract Deku from the water.”
“Uhh, you do know what happens to wings when they get wet, right?” She rolled her eyes as the older hero’s voice came over the radio. “They don’t work properly! Froppy, how far away are you now?”
“Three minutes, sir,” Froppy answered. Uravity flew closer to the water, where she had seen Deku go under.
“Deku!” No answer. Not even bubbles on the surface. Her heart was pounding and she hovered just over the edge. Her suit was too mechanical to go in herself. She could only hope Froppy would be here soon.
Under the water, Izuku Midoriya was channeling 90% of One For All so he could surge through the water after the villain. How the hell was this guy such a good swimmer? He hadn’t seemed to have any aquatic qualities, like his good friend Froppy. She was clearly part frog, and she was usually the one assigned the water assignments. But as he had told Uravity, they didn’t have time to wait for her. This villain had been evading them for months and Izuku was SO close to catching him at last.
He blinked, his eyes stinging from the water. His legs were tired, his lungs ached but he propelled forward, until a flash of light nearly struck him. He rolled sideways, looking around frantically and accidentally releasing a cry of surprise.
The villain he had been pursuing wasn’t even human… well, he was half human. But his legs had disappeared and instead, he had a powerful tail. A dorsal fin had emerged out of his back and his hands were covered in scales and ended in long claws. When he smiled an evil smile, Izuku saw long sharp teeth.
“Impressive, little hero. But I imagine you are running out of breath. I could just sit here and watch you die.” Izuku’s eyes flashed and he held out his hands. Black Whip emerged, clearly surprising the villain, and wrapped around the tail. Izuku was yanked forward as the villain thrashed around, trying to bite at the black tendrils that entrapped him. But Black Whip was no rope or chain. It couldn’t be bitten through and Izuku held on tightly as he channeled more of One For All, shooting up toward the surface. The villain roared angrily, thrashing his tail and took off downwards. Izuku was already feeling the lack of air and he channeled 100% of his quirk to keep the villain from going any further down. He kicked out his heels and felt a sharp pain in his leg as the razor-like tail sliced through his uniform. He glanced down to see a cloud of blood appearing and swallowed nervously. He knew sharks were drawn to blood. If he didn’t get this villain to the surface soon, he was dead for sure.
The villain froze at the sight, or smell, of blood. His nostrils dilated and he bared his teeth. Izuku used the distraction to his advantage, wrapping Black Whip around his hands and pulling the villain closer. Izuku felt a force join him and he glanced sideways to see Froppy pulling at Black Whip, trying to help him drag the villain out of the water. He sighed with relief and shot her a thumbs up before kicking his legs and angling his body upwards.
He was starting to feel weak. The adrenaline was wearing off and now he noticed just how badly his lungs were burning. He wanted to go up and take a breath but Black Whip was what was trapping the villain right now so he couldn’t leave Froppy. His friend started gesturing and Izuku turned, his eyes widening when he saw another of their friends coming toward them. Ingenium, known for his speed, joined them and immediately grasped Izuku around his waist. Izuku shook his head but Ingenium ignored the hero, putting on a burst of speed and propelling them to the surface. As they broke through the water, Izuku took a deep breath and felt his lungs expand. At the same time, he felt something scratch his arm. Ingenium refused to release him as he sped them to shore, other heroes waiting anxiously.
“Deku, I’m going to murder you,” Uravity exclaimed.
“Sweetheart, save it for when we are inside and away from the crowd,” Ingenium muttered as he dried himself off and turned to redress in his heavy hero costume.
“I wasn’t about to let this asshole get away again,” Izuku snarled.
“Speaking of asshole, I think he scratched you,” Uravity nodded toward Izuku’s arm. It was bleeding and Izuku held up his arm. The villain noticed and his eyes widened.
“Damn it!”
“What, meant to scratch me deeper?”
“I didn’t mean to scratch you at all. Shit! You don’t deserve this power.”
“What are you talking about, villain,” Ingenium frowned.
“Nicely done, Deku,” Hawks appeared at his side and pat Izuku on the back. “You too Froppy and Ingenium. Glad we decided to partner up several agencies to catch this guy.”
“Um, Pro Hero Hawks, sir, what would you like us to do with him?” Hawks raised a brow.
“Well… he needs water, obviously. Guess we finally know the identity of the Sea Villain. See if you can get a tank installed in Tartarus.” The Sea Villain let out several colorful curses which made Hawks look only more amused. The police dragged him away and Uravity lifted Izuku’s arm.
“You’ll want to have that looked at. It doesn’t look good.”
“I’ll be fine,” he said dismissively. “I need to get back to the agency to fill out some paperwork. Iida, can you take Ochako home?”
“Of course but she’s right, MIdoriya, that wound looks serious.”
“I’ll have the Healer at the agency take a look at it. I’ll see you guys tomorrow night, right?”
“We will be there,” Uravity nodded eagerly. “I feel like we haven’t seen Todoroki in years!” Izuku nodded, smiling. He loved his boyfriend dearly but Shoto Todoroki was very much a homebody and didn’t go out much. For Izuku’s birthday, however, he had talked Shoto into letting him have their old classmates over for drinks and games. Izuku was looking forward to seeing everyone.
He hugged his three friends goodbye, said goodbye to the other heroes and police, and kicked off into the air, heading toward his agency.
------------------------------------------------------------------------------------------------------
He noticed something was off as soon as he landed. He started to sway on the spot and his vision was blurred even as he blinked rapidly.
“Guess I really do need to have this checked out,” he muttered, glancing at his arm. He made his way into the agency and nodded as assistants called out to him. As he hurried along the halls, he started to feel weaker and weaker. He put his hand to his head and frowned.
“What the hell,” he mumbled to himself, picking up his pace.
“Midoriya,” the Healer didn’t look surprised to see him. It had been a long time since he had broken his bones due to his quirk but that didn’t mean he didn’t hurt himself on the regular.
“Hey M, I need you to take a look at something.” He held out his arm and the Healer clicked her tongue.
“What on earth?”
“A shark man scratched me.”
“A shark man.”
“I guess it was his quirk. The Sea Villain. I thought I was fine but I started to feel really dizzy… lightheaded and stuff. I can barely see right now. What’s going on?”
“I’m not sure. Sit.” He took a seat where she was gesturing and studied his arm.
“What happened to your leg?”
“Oh.” He had completely forgotten. He rolled up his pants leg and made a face. “He hit me with his tail.”
“I see some strange things on the job but you, Midoriya, you always have the strangest accidents.”
“Can’t say I disagree with you but I think some heroes face weirder. Can you fix it?”
“I’ll clean it and put some healing salve on both wounds. Undress for me.” Izuku sighed and stripped out of his hero uniform, leaving him in his Pro-Hero Shoto boxers. The Healer quirked a brow and bit her lip to keep from laughing.
“I like wearing my boyfriend’s merchandise,” he said defensively.
“I didn’t say a word,” she held up her hands and shook her head. Izuku crossed his arms as she went to work on his leg. The gash wasn’t too deep and she cleaned it quickly. She wrapped a bandage, then turned her attention to his arm.
“This wound is… strange.”
“So you keep saying. What’s so strange about it?”
“Was it oozing like this before?” Izuku frowned and looked down. Sure enough, a thick black substance was leaking from the wound and dripping down his arm.
“That’s weird.”
“As I keep saying. So I’ll take that as a no. Let’s clean it and then we can study it properly.”
-----------------------------------------------------------------------------
Uravity's head was spinning as she tried to navigate the halls of the agency. She was more comfortable in her smaller agency, run by the Pro Hero Ryuku. But Deku was her friend and she wanted to check on him.
She turned the corner and nearly ran straight into her old classmate. Katsuki Bakugo was laughing about something and Uravity knew that was never a good thing.
"Hey Sweet Cheeks, what are you doing here?"
"I wanted to check on Deku. He was injured on assignment and--" Bakugo let out a loud laugh and clutched his stomach.
"Oh my god, so you haven't heard yet? Just wait till you see!"
"See what? Bakugo, is Deku alright?"
"Oh he's fine," Bakugo waved, still laughing. "I can't wait till his boyfriend sees him though."
"You are such an ass," she said through gritted teeth. "Where is he?"
"Locker room. He won't come out." Shaking her head, she turned and headed toward the hero locker rooms.
------------------------------------------------------------------------------------------
"Hey Todoroki, thought it was your day off?" Pro Hero Shoto Todoroki waved to his co-worker as he made his way to his office.
"Got called in. Has anyone seen Deku?"
"He was on assignment this morning but I heard he returned a few hours ago." Shoto hummed. Why hadn't his boyfriend texted him that he was back at the office? They always let each other know they were back and safe when they had assignments. Too many heroes never made it back safely and Shoto and Deku had learned quickly that it eased their anxiety when they texted each other back in the office.
He pushed his office open and froze when he saw an old classmate.
"Uraraka."
"Hey," she sounded nervous. "Thanks for coming in."
"Well, my boss made it sound important so I--" he trailed off, his eyes narrowing. "Wait. You had her call me in, didn't you?"
"I didn't want to alarm you but it IS important!"
"Is Izuku alright?" Panic filled his voice so Uravity held up her hands placatingly.
"He's fine! He was, uh, hit by a quirk while he was on assignment. He got scratched and apparently that's how the quirk is transferred. The Healer cleaned him up but he's, uh, hiding out in the locker rooms." Shoto turned on his heel without another word.
"Wait!"
--------------------------------------------------------------------------------------------------
Uravity stayed right behind him as they made their way to the lower level, where the showers and lockers were. Bakugo was leaning against the wall, laughing with his sidekick.
"Oh you're in for a nasty surprise, Icy Hot," he cackled.
"Fuck OFF, Bakugo," Uravity snapped. Shoto hastily pushed the door opened and stepped in.
"Izuku?"
"Shoto? Wha-- what are you doing here?" Shoto turned, trying to place where his boyfriend's voice was coming from.
"Uraraka called me. Well, she had Mirko call me but now I'm worried. Are you alright?"
"I'm fine," he said in a high-pitched voice that told Shoto he was clearly lying. "I'll, uh, I'll just see you at home!"
"Not a chance I'm leaving you. What kind of quirk is it? Maybe I can help."
"Uh, you can't. And I'd rather... you not see me like this."
"Izuku," he said patiently, walking toward the back showers. "I'm your boyfriend. Nothing about you is going to scare me." He heard Izuku sigh loudly.
"You're so stubborn," his boyfriend mumbled. Shoto smiled and pulled the shower curtain back.
Izuku was sitting on the tile floor, his green curls soaking wet while the water rained down on him. He was shirtless and for a moment, Shoto wondered why he was sitting on the floor. As he was opening his mouth to ask, however, he spotted
something flopping around where Izuku's feet should have been.
"Is that a tail," was all he could think to say. Izuku blushed.
"Technically, it's a fin."
"You're a fish?"
"Technically, I'm a merman," Izuku said irritably. "Part human, part fish." Shoto gaped at his boyfriend. He noticed Izuku also now had long, sharp teeth.
"Who the fuck did this to you?" Izuku sighed and quickly explained that they had finally caught up to the villain who had been evading them for so long. It seems, Izuku noted, that the villain hadn't meant to scratch him and the Healer had assured him the effects should wear off by tonight, morning at the latest.
"So... you have to stay in the water?"
"Not all the time but I was feeling very dehydrated and dizzy and when I got into the shower, I felt better."
"Ok then." Shoto knelt down and scooped his boyfriend into his arms. Izuku cried out and flung his arms around Shoto's neck.
"What are you doing?"
"Taking you home," Shoto stated as if it was the most obvious thing in the world.
"You want to take me out in public like this?"
"We'll use the back way and I can have Uraraka drive my car around. Heroes get hit by strange quirks all the time, 'Zuku."
"Think this is the strangest," Izuku lifted his fin. Shoto raised a brow and slowly nodded.
"It's... not something you see everyday. But no matter, you're still my beautiful 'Zuku." Praise was Izuku's undoing and Shoto knew he had won as his boyfriend's cheeks grew pink. Shoto grinned and kissed Izuku's forehead.
"Let's get you home."
Uravity hurried off to bring Shoto's car around while Shoto found a blanket to wrap Izuku in. Bakugo chuckled and nudged Shoto.
"No birthday sex for Deku, I guess."
"Kachaan!" Izuku hid his face in his hands and Shoto looked at their friend calmly.
"The quirk should wear off by morning. So he can get a full day of birthday sex before his party."
"Oh my god, Shoto!" The blush now spread to Izuku's ears and neck. Shoto thought it was quite adorable.
"See you tomorrow night, Bakugo. Please be sure to knock loudly, as we might still be preoccupied when you arrive. Izuku can be quite vocal." Shoto said in the most nonchalant tone, as he carried his quirked and very red boyfriend out to the car.
--------------------------------------------------------------------------------------------------------------------
"Alright, here we are." Shoto gently lowered Izuku into the tub and moved out of the way to avoid being hit by Izuku's powerful tail.
"Thanks," Izuku said weakly. "It's ridiculous that I can't last very long out of the water."
"That's what you find ridiculous about this situation?" Izuku gave him a pointed look. They had been home for an hour when Izuku had started to complain of a headache. Shoto had immediately gone to fill the tub, leaving Izuku on the couch, and had returned a moment ago to carry him to the bathroom.
"Should I add some salt to the water?" Izuku quirked a brow as Shoto held up the container of salt.
"You really do think of everything."
"I mean, I'm perceptive. I always have been. But I don't think of everything." Shoto added a generous amount of salt to Izuku's bath water and Izuku leaned back against the wall.
"Would it be weird to ask you to join me?"
"I think the tub is rather small for that, 'Zuku." Izuku pouted, which made Shoto chuckle. He reached up and pushed a strand of green hair out of his face.
"I know, I just... like having you close."
"I'm right here, love. And you'll be back to normal tomorrow. Just in time for you to have a great birthday with all of your friends."
"What did I do to deserve you, Shoto Todoroki?"
"I fell in love with Izuku Midoriya before I even knew what love was," he traced Izuku's bottom lip with his thumb. "And every day, you continue to amaze me. Every day, I just love you more." Izuku blushed and leaned forward. Shoto met him halfway and their lips crashed together. Izuku released a needy moan as he felt Shoto's tongue on his lips. He opened his mouth and Shoto's tongue slid inside, tracing the newly sharp teeth.
"That's kind of hot," he murmured, causing Izuku's eyes to flutter. Shoto reached up and cupped Izuku's cheeks, deepening the kiss. He tore away, smiling at the petulant whine Izuku let out at being deprived of Shoto's lips but he made it up to him by planting kisses all over his throat. One thing Shoto loved about Izuku was his freckles. He was crazy about them, each and every one. Their first night being intimate he had spent hours tracing every one of them with his tongue. They made Izuku self-conscious but Shoto loved to take his time kissing every inch of his boyfriend's freckled flesh.
"Sho," Izuku panted as Shoto trailed his tongue down his throat and circled one of his pink nipples. Something caught his eye and he sucked in a breath.
"Well that's interesting."
"Huh?" Izuku opened his eyes lazily and peered down to see what had drawn Shoto's attention. His eyes widened in horror and he sat straight up. "What the hell?! Is that--?"
"I suppose it makes sense," Shoto said calmly. "You are a mer, after all."
"But... but TWO of them?"
"Didn't you say the villain was half shark? I've read that sharks have two penises. So yes, this is logical."
"NOTHING about this is logical," Izuku said, looking stricken. "Oh my god, I'm a freak!"
"Zuku," Shoto laughed, cupping his chin. "You're adorable, do you know that?"
"This doesn't freak you out? I'M freaked out right now."
"I think we can have some fun with this," Shoto lowered his voice and Izuku shivered. Shoto trailed his hand down Izuku's stomach and lower, nudging Izuku's two cocks with the back of his hand. Izuku inhaled sharply and Shoto closed his fist around one of them. He reached in with his other hand and grasped the other, sliding his palms up and down.
"Oh god," Izuku clutched the edge of the bathtub.
"How does it feel, Zuku?"
"So good," he moaned in response. "Please don't stop."
"See? It's still you. It's still giving you pleasure. And that's all that matters." Shoto leaned in to kiss his boyfriend and Izuku leaned back against the wall again. Their tongues clashed together for a moment until Shoto moved to lick at the edge of Izuku's ear.
"Fins or feet, you still drive me insane, my Izuku."
"That's, uh, not something I ever thought I'd hear come out of your mouth, Sho." Shoto hummed as he leaned over the tub and wrapped his lips around one of Izuku's dicks.
"Sho!" Shoto hummed again and traced the wriggling appendage with the tip of his tongue, before pressing them together and opening his mouth wide.
"Fuck Sho, you're not--" He let out a strangled cry as Shoto took both dicks into his mouth. His jaw was aching in minutes but it was well worth it to hear Izuku's cries echo off the bathroom walls.
"Shoto... that can't be comfortable! Your poor back!"
"If you can worry about my back, then I'm not doing my job properly," he muttered, licking up and down the shaft. One of them started to wrap itself around Shoto's hand and their eyes widened.
"These things have a mind of their own," Izuku said, half in horror, half fascination. Shoto pulled his hand away and Izuku blinked up at him as he started to remove his clothes. Izuku's eyes were drawn to Shoto's hard cock as Shoto brought his hand down and gave it a few strokes. He smiled down at his boyfriend and stepped into the tub, stepping over Izuku, straddling him. He pressed his palms against the wall and glanced down at him.
"Open me up, Izuku. I want to ride you right here and now."
"Fuck, Shoto, are you sure?" Shoto bent his knees a little, pushing his ass out toward his boyfriend and Izuku eagerly responded. He gripped Shoto's strong thighs and kissed both cheeks, before moving his hands up and spreading him open.
"God Shoto, you're glorious."
"You could do so much more with that mouth of yours." Izuku smirked and dove right in. Shoto pressed his cheek against the cold tile as Izuku licked him open, spearing his tongue in and out. Shoto's teeth dug into his lip as he scrabbled around for something to hold onto. Izuku pushed two fingers in and Shoto's knees nearly buckled.
"So glad I don't have claws," Izuku muttered against Shoto's warm skin.
"M-me too," Shoto panted. "More Izuku, I can take more!"
"I don't want to hurt you, Sho."
"I'm not going to break!" Izuku sucked on his fingers and thrust three of them inside Shoto, moaning at how tight his boyfriend was. He moved his free hand between Shoto's legs and cupped his balls in his palm.
"Gah! Enough of that. I'm so close already."
"Then come here." Izuku gently pulled Shoto down on top of him, their cocks rubbing together. Shoto lifted up and reached behind him, easily sliding Izuku inside him. They both cried out as Shoto leaned forward and wrapped his arms around Izuku's broad shoulders.
"You feel incredible, Sho."
"Nngh! Zuku! Oh fuck." Izuku's scarred hands gripped Shoto's ass, bouncing him up and down. Shoto paused, leaning forward on his knees and reached behind him again. Izuku's brow furrowed until he felt Shoto's hand close around his other dick and his eyes widened.
"Shoto, wait!" But Shoto slid Izuku's second dick inside him, pressing against the first. He squeezed his eyes shut at the sensation of two dicks rubbing against his soft walls.
"Shoto!"
"Fuck me, Izuku!" He leaned forward and wrapped his arms around Izuku, hiding his face in Izuku's neck. Izuku bucked his hips, clenching his teeth and doing everything he could to keep from cumming yet. But it felt amazing. Twice the pleasure, even.
"Sho, I'm gonna..." He reached between them and closed his hand around Shoto's weeping dick, his roughened palm making Shoto moan. Shoto's walls became even tighter as he painted both of their chests, and Izuku threw his head back with a cry. Shoto clenched around him and Izuku felt himself go soft inside him. Shoto grunted as he stumbled to his feet, turning around to pick up the shower head. Izuku stared at Shoto's winking hole, his eyes widening at just how much cum was leaking out.
"Oops," he mumbled and Shoto glanced over his shoulder. "Sorry, I think I just came more than I ever have in my entire life."
"I'll take that as a compliment," Shoto winked. "Now help me clean up."
------------------------------------------------------------
After taking an actual shower and drying off (Shoto, anyway), Shoto carried Izuku to bed. He set a large basin of water beside the bed, in case Izuku needed to dip his fin in during the night. Izuku curled up into Shoto's chest, tucking his fin between Shoto's legs. Shoto left a soft kiss on Izuku's forehead before they fell asleep rather quickly.
Shoto opened his eyes and squinted at the bright clock. 1:05. Why was he awake then? He felt something cold on his leg and he shivered. He moved away but Izuku chased him in his sleep, both feet finding Shoto's warm thigh.
"Hey," he grunted. "Keep those icicles to yourself."
"You're so warm," Izuku mumbled. Shoto hummed, before his eyes flew open. He glanced down and threw the blanket off.
"Zuku! Look!"
"Huh?" Izuku lifted his head and frowned at Shoto. "What?"
"You have feet. They're fucking freezing."
"I have..." his eyes widened and he held his leg straight up. "I have legs!" He laughed happily, running his hands up and down his leg.
"Let's see." Shoto cupped Izuku's chin and kissed him. Izuku's eyes flew open as Shoto forced his tongue into his mouth. "No more shark teeth."
"Oh thank the stars above," Izuku leaned back against the pillow. "That was miserable."
"Really? You were miserable the whole time?" Izuku smirked and shook his head.
"OK, some of it was really enjoyable. But you know what's going to happen now, don't you?"
"You're going to fuck me properly?"
"Properly? Shoto, you had TWO dicks inside you."
"Do you want two dicks inside you, Zuku?" Izuku swallowed as Shoto hovered over him. Shoto was more lithe and not as broad as Izuku was but he was still intimidating.
"You're the ONLY one I ever want inside me, Shoto Todoroki," he said firmly.
"That makes my heart happy but that's not what I'm talking about, love." He climbed off Izuku and crossed the room to their shared drawer. Izuku leaned up on his elbows and watched Shoto approach, holding several things in his arms.
"I thought you were trying to suggest a threesome and I was about to question everything." Shoto's brow raised high into his hair.
"You think I would ever let anyone else see you, let alone touch you?"
"No," Izuku giggled. "You're too possessive."
"You're mine," Shoto said simply. "No one else's." Izuku nodded and sat up to kiss him.
"I'm yours."
"Lie back for me." Izuku did as he was told and Shoto settled between his thighs. He coated his fingers in the lube and circled Izuku's rim with his fingertip. Izuku reached down and spread himself open, opening his legs wider.
"Such a good boy for me," Shoto crooned. "So beautiful." He pushed his finger inside, then slowly withdrew it. Izuku's hole clenched around him, as if trying to keep him inside. He added another a finger and spread them wide inside him. Izuku clutched the blanket with white fists and Shoto increased his pace. He bent down and trailed his tongue down Izuku's shaft, causing it to jump against Izuku's stomach. He took Izuku in his mouth and sank all the way down, smiling to himself at how far he had come since the first time he had gone down on his boyfriend.
Izuku was so thankful for his boyfriend's dexterity as he was scissored open, while Shoto's tongue laved his cock.
"Sho," he gritted his teeth. "Too close!" Shoto pulled off, giving Izuku's head a kiss, before picking up the toy he had brought with him. He held it up for Izuku to see and Izuku nodded, biting his lip. Shoto poured lube over the toy and slowly pushed it inside Izuku.
"I picked one of the small ones," Shoto said in a serious voice. "I don't want to hurt you."
"What did you say earlier? I'm not going to break." Shoto smirked and pushed the dildo further inside before pulling it back out. Izuku jerked his hips and grabbed for Shoto's hand. Shoto pushed the dildo all the way in and bent down to give his lover a filthy kiss.
"I love you."
"Sho. I need you."
"Yeah? You ready for me too?" Izuku nodded and Shoto pulled one of Izuku's legs over his shoulder, opening him even wider. "If anything gets to be too much, you tell me immediately." Izuku nodded again and Shoto held himself while he pushed inside. Izuku was extraordinarily tight and he winced at the stretch. Shoto, of course, noticed and started to pull out, when Izuku crossed his legs over Shoto's ass and held him still.
"Don't you dare," he growled.
"Izuku! Fuck you're so tight!" He grasped the dildo and echoed his own movements. Two cocks thrusting in and out of him was making Izuku lose his mind and his hands covered his face.
"Shoto," he whined. "So close!"
"Are you going to cum on my cock, Zuku baby? You are so fucking perfect, do you know that?" Izuku relished when Shoto lost his inhibitions like this. Usually so reserved and poised, but he let loose in the bedroom and let the dirty talk fly. Izuku absolutely loved it. It meant that no one but him ever got to see this side of Pro Hero Shoto.
"Fill me up, Sho. I'm yours!"
"You're so amazing, love. You take me so fucking well, your ass was made to fit my cock. Fuck Izuku, you feel so good!" Izuku released a strangled cry and his own cum splashed him in the face. Shoto followed only moments after, setting the dildo aside and filling Izuku with his warmth. Izuku's legs fell to the bed, his chest heaving up and down as his hand fell over his eyes. Shoto softly kissed Izuku's hipbone before climbing off the bed and grabbing a towel from the corner. He dipped it in the basin water and quickly cleaned up his sleepy lover. He tossed the towel aside and pulled the blanket over both of them as he settled in beside Izuku. They both loved post-coital cuddles and he sighed contentedly as he settled his head over Izuku's racing heart. Izuku brought his hand to Shoto's messy hair, Shoto's eyes fluttering closed.
"I love you," Izuku said in a raspy voice.
"I love you too," Shoto mumbled against his skin.
"Best birthday ever," Izuku sighed as he stretched out.
"Really? And it's barely begun."
"Mmhm," Izuku hummed, already falling asleep.
And Shoto made sure it really was the best birthday ever. He woke Izuku up with a sensual blowjob, followed by breakfast in bed and then him riding the birthday boy in the bedroom and the shower. He hadn't been lying to Bakugo when he said Izuku would have a full day of birthday sex.
And that night at Izuku's birthday party, Shoto dropped to one knee in front of their friends and asked his boyfriend to be his husband. Uravity and Ingenium, who had known about the proposal, gifted them plane tickets to America, where they could have a legal ceremony. Bakugo and Kirishima wrote checks to cover the price of a romantic hotel and Izuku spent the rest of the party crying the happiest tears.
Their friends questioned them about the capture of the Sea Villain and Froppy turned to Izuku.
"Is it true that you turned into a fish?"
"Technically he was a merman," Shoto said calmly.
"Technically he had a fish dick," Bakugo cackled. "Who cares what he was called, he had a goddamn tail!"
"Fin," Izuku and Shoto said in unison.
"Well, regardless of what we call it, I'm glad you're back to normal, Midoriya," Iida lifted his glass. "That must have been awful."
"Oh, it really wasn't so bad," Izuku said with a sideways glance at his fiance. Shoto hid his smile in his glass of champagne and started to wonder what other sorts of kinks he had that he didn't know about.
END
