Fading Heat

Chapter Text

It had been easy to not think about the fact Midoriya was an Alpha. Even though Toshinori had spent enough time around him to see there was no trace of metallic silver scales to mark him as a Beta, or gold to mark him as Omega. His horns were small and solid black, mostly hidden under his curly green hair, and the scales on his wings and tail were a deep emerald green with blue iridescence giving them a teal cast, shading to more black on the tips.

Maybe it was because when they first met he hadn’t needed to worry about it. Midoriya was young enough not to be affected by his pheromones back then, and it was strange to think of how much time had passed since then. When Midoriya had asked to meet up to ask his advice on something, Toshinori readily agreed even if the timing was less than ideal. It was hard to predict when his heats would come, after his injury the healers had told him he might not even be capable of cycling any longer. Instead he still did, but they were unpredictable and there could be a great deal of time between each one. It had been long enough that he nearly always suspected that the previous heat had been his last until he woke up to the familiar feeling of laziness and the sweet ache under his tail.

Normally he’d have called off something so minor, but it was only the first day and he’d pushed through much worse in his time. There was also the nagging fear in the back of his mind that one of these days Midoriya wouldn’t want his advice any longer. He’d already achieved greater mastery over the magic Toshinori had passed on than Toshinori ever had, even if he wasn’t sure Midoriya would admit it yet, and he was well on his way to being known as a greater mage than he had been. He was maybe being a little sentimental, not wanting to give the final push to have Midoriya standing entirely on his own, but it wasn’t as though he was holding him back any. Most of the time he was able to offer him decent advice, or steer him towards working out the problem on his own, and he dreaded the day he wouldn’t be of any use to him anymore.

For the time being though he would cherish the times they spent together, even if he was more than a little distracted.



Midoriya didn’t make him wait in the reception area, he was sent right in and to his office and Toshinori was grateful for that.

“It’s good to see you.” Midoriya was jumping up, almost too quickly, wings relaxing out a little in the excited way he did sometimes and Toshinori smiled at the sight.

“It’s good to see you too,” Toshinori said, glancing around. “It looks like you’ve settled in a little more.” The time he’d visited before the office was stark, only a few small generic decorations that likely someone else had gotten or had come with the room. Now though he could see little touches that, while still professional, looked far more personal.

“Sometimes I can go an entire hour without feeling like someone’s going to come in and tell me I’m in the wrong place and to hand things over to someone who actually belongs here,” Midoriya said, sounding amused as he motioned for Toshinori to sit.

Toshinori took the offered seat, unable to stop the way his tail curled restlessly behind him, coiling around the chair leg and then releasing it as it kept moving. With luck even if Midoriya noticed he’d be too polite to mention it. It was frustrating that he always felt both restless and lazy as he started into his heat, instincts telling him to go out and find a mate to take care of him.

“That gets better in time,” Toshinori chuckled, telling himself to focus. “You mentioned you wanted some advice?”

“I did. I have some upcoming appearance requests and I wanted to ask your opinion on them,” Midoriya asked, and Toshinori smiled, relaxing a little. Asking around about the public appearance side of being a professional mage was normal, even seasoned pros did it, and he could tell him his experiences and feelings on the events without guilt that he was holding him back.

Toshinori was enjoying himself, despite the distraction. If the timing hadn’t been so bad he’d have suggested they grab something to eat on Midoriya’s lunch break. Gradually though he became aware that Midoriyalso seemed distracted, pausing in the middle of whatever he was saying or needing Toshinori to repeat himself. For just a moment he felt a stab of guilt, wondering if Midoriya was just humoring him at this point, then he noticed the faint flush under the freckles scattered across his cheeks and oh.

Toshinori could have kicked himself, another Omega wouldn’t have been affected and a Beta would have needed to get much closer for longer, but in an enclosed space like this he was more than close enough to drive an Alpha crazy. Now that he was paying closer attention he could see the way Midoriya’s pupils were dilated and that his breathing had sped up.

“Midoriya-shonen...” Except not so young anymore, not too young to be bothered because an idiotic old lizard went out without thinking. Toshinori cleared his throat, standing up. “Maybe we should continue this later?”

“Don’t go,” Midoriya said, too quickly and with a note of desperation to it. He was trembling a little, and Toshinori hesitated. If he left now Midoriya would be useless for hours until the rut worked its way out of his system. He shouldn’t leave him like that, but… it was hard to think of reasons he should go, even if he was sure he probably should. What if Midoriya was needed?

“Sit on the desk,” Toshinori said, roughly and with a hint of a purr to it as Midoriya flared his wings out eagerly, shoving papers out of the way as he sat on the desk facing him. Toshinori purred deep in his chest, reaching to start unbuttoning his pants and tugging them down.

He didn’t have to do too much, he could care for Midoriya like his instincts were begging him to and fix what he started and almost as soon as he had his pants down he was leaning forward to press his face between his thighs, nuzzling at his mound and licking over his slit. He could feel Midoriya gasp almost as much as he could hear it over his own low moan at how good he tasted. Midoriya’s hands wrapped around his golden horns, holding him close. He didn’t need the urging, but he loved feeling how eager he was.

Midoriya was already soaked as he pressed his tongue in, curling it against his hard clit. Izuku bucked his hips, squirming under the attention and Toshinori wrapped his hands over his hips, trying to hold him still. He knew he was making needy little sounds as he kept licking lower, pressing his tongue in deep and muffling the noises as he curled his tongue inside him. Midoriya nearly roared at that, holding tight onto his horns as he came hard in a rush of fluid that spilled out and down Toshinori’s chin.

Toshinori could have stayed there all day, but he pulled back reluctantly, panting softly and looking up at Midoriya. The other dragon looked dazed, but he recovered much faster than Toshinori would have thought possible.

“Come here,” Midoriya let go of his horns to stroke over his cheeks and then urge him closer. Somewhere in the back of his mind Toshinori was aware he had intended to leave, but he could still taste him and he was aching so badly he could hardly stand it. It was taking all his self-control not to take care of himself right in front of him, and he didn’t have it in him to resist when Midoriya tugged him closer and then started unfastening his pants.

“I should…” Toshinori started, and then lost his train of thought as Midoriya pulled him up into his lap, rocking up against him with a gasp that Toshinori echoed. When had he gotten so much stronger? He clung to him, wings arching back a little to keep himself balanced and tail curling around one of Midoriya’s legs and holding tight.

“Just like that,” Midoriya muttered, holding his hips as he moved, rubbing against him. Toshinori moaned, holding onto him helplessly as he rubbed his soaked slit firmly against Midoriya’s. It felt so good to have an alpha’s attention and he nuzzled close, nipping at one of the small black horns. Midoriya was perfect like this, solid and strong and Toshinori couldn’t even think of holding back.

Midoriya gasped, holding his hips hard enough to leave bruises as he rocked up, coming in a second rush. Toshinori wasn’t sure if there was more this time, or if it only felt like it as he was flooded and filled with the hot fluid. He came hard, back arched as his body trembled, it felt like everything inside him tensed perfectly to try and keep anything from leaking out and making any more of a mess between them.

Slowly though he relaxed, ducking his head to nuzzle tiredly at curly green hair as Midoriya wrapped his wings around them both, holding him close.




“I need to go,” Toshinori said, reluctantly as he slowly eased away from Midoriya. As soon as he lost the contact he missed it.

“I know.” Midoriya took a deep breath, tensing like he was keeping himself from reaching back out to him. “If you don’t we’ll end up doing this all day.”

Toshinori could think of much worse ways to spend an entire day, but he nodded, tugging on clothing and trying to make himself look at least halfway presentable for the trip home. He hesitated in the doorway, trying to think of what he could possibly say after all of that.

“I’ll see you later?” It was as much a question as a statement, but Midoriya’s eager nod relaxed something inside him that he hadn’t realized had tensed up, and he let himself out of the office, starting out quickly.

He knew if he was smart he should probably stop off and get a spell to prevent pregnancy, they were easy enough to come by. Midoriya probably would have even done it for him, if he’d asked, but…

The thought that it might truly be his last heat this time made him reluctant. He might never get a chance to do this again, and that thought was a little sadder than he expected it to be. With that in mind he didn’t bother to stop, heading home alone to deal with the rest of his heat.

Chapter Text

 "I suppose you're all curious as to why I'm taking some leave time," Toshinori addressed the gathered teachers, expecting at least a little curiosity. 

"Because you're close to your due date, right?" Midnight asked. Toshinori floundered, his prepared speech suddenly rendered useless. 

"I, yes, how did you know?" Toshinori asked in disbelief.

"How would we not know? You've been looking like you swallowed a cannonball for weeks now," Vlad drawled, and Toshinori rustled his wings and switched his tail, swallowing back an annoyed huff. 

He'd been so careful, he thought, it wasn't as thought he was any stranger to loose fitting clothing and he thought he'd chosen well to conceal the growing bump.

"Not true, Aizawa insisted it could be some sort of giant tumor," Midnight pointed out. 

"A tumor could be removed and wouldn't potentially be a troublemaking student in a decade and a half," Aizawa piped up. 

"That aside, the only serious bets have been on who the sire is, when you're ready to make that announcement someone is going to end up making a lot of money," Midnight said cheerfully.

Toshinori cleared his throat. "Anyway, the important part is that I'm going to be taking some time off for my dragonette, I already spoke with the principal to get my classes covered, and I'll likely just wait until the start of next year to return."

Toshinori accepted the well wishes that ranged from sincere to obligatory, but his mind wasn't truly on them. If he hadn't done as good of a job concealing his pregnancy as he thought, who else had noticed?



"I'm taking some time off work," Toshinori said, watching Midoriya's face.

"Ah, that's... why is that?" Midoriya asked, and Toshinori was certain he saw his gaze dart to where his middle was half-hidden by the table, and then back to his face. It wasn't that uncommon for them to meet for lunch and Toshinori was glad he could make plans to meet like this without seeming suspicious.

"I'm going to be having a dragonette," Toshinori announced, even if Midoriya possibly already knew, he at least wasn't denying him the chance to say it. He appreciated that.

"Congratulations," Midoriya said warmly, and Toshinori smiled. There was genuine emotion in the word and he'd hoped Midoriya would be happy with the announcement. 

"Thank you," Toshinori settled back a little, taking a bite of his sandwich.

"Ah, forgive me if this is rude, do you plan on raising them alone or are you going to be raising them with their sire?" Midoriya sounded hopeful and Toshinori felt a pang. He'd considered keeping it a secret as long as possible. Midoriya was a young man, he had a very long life and career ahead of him. There was no reason to tie him down to a family so early, especially when he'd never even discussed it with him. Heat-sex had been an impulse decision, one he didn't regret for a moment, but just because Midoriya wanted sex with him didn't mean he wanted a family with him.

"I don't know, it depends on what the sire wants," Toshinori said, delaying just a little. "I haven't told them yet."

"Who is it?" Midoriya asked, and he sounded so hopeful and looked so worried.

"It's you, Midoriya-shonen," Toshinori admitted. "I understand if you don't want to be tied down, but..."

"Yes!" Midoriya exclaimed, excited enough to interrupt. "Yes I want to raise a dragonette with you, yes I'd love to be mates with you. I've been wondering ever since we were together if it was mine and you wanted me, but I didn't want to assume. And... yes, what I mean is yes, I want as much as you're willing to give me."

Toshinori was startled by his obvious enthusiasm, smiling a little dumbly. He'd never even begun to hope that Midoriya would want him, much less so fervently. 

"Then I would like that very much, Midoriya-shonen." 



Toshinori didn't usually have people over at his house. Part of it had been he hadn't expected to be teaching for long and so it still seemed to him it had that awkward feel when you overstay somewhere meant to be temporary. Little things like getting good shelves or fixing minor annoyances pile up, but there doesn't see to be much use in putting in a lot of time and effort into somewhere you're just going to leave. It was still hard to think that he'd need to either start thinking of it as permanent, or find a place more suitable for a mate and dragonette. 

A mate, the thought still made him feel warm, and it was Midoriya who was always so kind and wonderful and knew him better than anyone else. He deserved so much better than an old lizard, but if he wanted Toshinori then he couldn't find the heart to deny him. 

If Midoriya found anything lacking in his home he didn't say anything, turning to him almost as soon as they were through the door. 

"May I? Please?" Midoriya made a reaching gesture and Toshinori was confused for a moment until he realized what he was asking and nodded. 

"You may," Toshinori said, feeling the heat rise in his cheeks as Midoriya reached out as soon as he was given permission, stroking over his bump through his clothes. 

"Your dragonette, our dragonette." Midoriya touched over his belly slowly, making a startled sound and his wings flaring a bit at the flutter of movement under his hand.

"Our dragonette," Toshinori echoed, feeling warm under his hand, then Midoriya was moving closer and leaning up and Toshinori bent down eagerly to meet his kiss. 

He had thought about it a lot, sex that was driven just by affection and mutual desire instead of the overwhelming urgency of heat. 

"I worried you'd found someone else after you left me, I hardly dared to hope..." Midoriya murmured as he broke the kiss, voice a little deeper than usual. 

"No, it was only you." Toshinori stroked over the inside of one wing, watching it shiver at the gentle touch.

"I want you so much," Midoriya said, looking up at him so intently that all Toshinori could do was make a helpless sound and press their lips back together. 

Midoriya helped him with each layer of baggy clothing, unfastening them from around his wings and tail so slowly and carefully that Toshinori wanted to demand he hurry. Instead he swallowed his impatience and let him get the concealing cloth away. He worried for a moment that Midoriya would be unhappy with what he uncovered. He knew about the scar, but not the way it partially stretched over the bump that poked out almost unnaturally sharply from his too-slender body. Midoriya knew that he carried, but not everyone found that attractive. 

"You're gorgeous," Midoriya murmured, stroking over the tight skin and scar tissue over his belly with equal devotion. Toshinori swallowed, petting his fingers through thick curly green hair.

"I'm so glad you find me so. You're so young and handsome, and I know I'm..." Toshinori was cut off with another kiss. 

"I think my mate is perfect and I don't want to hear him saying anything otherwise." Midoriya smiled with the words, but there was enough sincerity behind them that Toshinori found himself nodding.

He helped Midoriya out of his clothes just as tenderly, but a little faster. Magic was demanding of the caster and Midoriya reflected that, strong muscles under soft skin and scales. He could take his time like this, find healed scars he knew hadn't been there only a few years ago. He wanted to learn every inch and every freckle, but while he wasn't nearly as overcome as he was while he was in heat, he still wanted him badly.

They ended up in bed together, Midoriya showing no sign of minding that he was a little awkward settling on his side to try and keep his big belly from being in the way. He stroked over it once Toshinori was comfortable, then hesitated. 

"I, ah, as much as I want you, if you're not up for it like this..." Midoriya let the question trail off and Toshinori chuckled. 

"I promise you, I'm up for it," Toshinori took his hand, guiding it down between his legs. Midoriya made a soft startled sound when he encountered how wet he was, needing no additional encouragement to rub his fingertips over Toshinori's soft folds, pressing in. 

Toshinori bit back a moan at the attention, knowing he probably looked hopelessly over-eager, but it had been a long time since anyone else touched him and he'd wanted it so badly ever since he became pregnant. He spread his legs as much as he was able, not able to move as much as he'd like, but if anything that just seemed to encourage Midoriya and he settled in close, kissing over his neck while he rubbed over his aching clit. Toshinori felt his tail twisting behind him, curling and rumpling the blankets as his hips made small rocking motions. It was different from doing it himself, more unpredictable, and having Midoriya so close was intoxicating. 

"Please..." Toshinori moaned, gripping at the blankets. 

"Please what?" Midoriya sounded husky but so concerned and eager to please that Toshinori let out a little whimper, flushing at how he must sound. 

"I want to feel your fingers inside me, please...."

Midoriya made a soft moan at that and Toshinori shivered and felt a little better about his own sounds, and then he wasn't thinking about much of anything as he felt him ease off his clit and his fingers move lower, one pressing in. 

"Just like that," Toshinori managed, rocking against the touch. It was slender enough to slip in easily touching deep and rubbing inside him in a way that simultaneously made him want to melt into the bed and grab his hand and demand more, faster, harder. He settled for staying exactly where he was, aware he was making needy little sounds as Midoriya kept fucking him with his finger. And then Midoriya eased it out to start adding a second. 

The gentle stretching was almost too much and it seemed like no sooner did Midoriya press deep inside him than he was arching as much as his belly would allow, tensing around his fingers as he came hard. 

Toshinori panted, trying to catch his breath as he sagged on the bed, feeling so good like this. He didn't really want to move, but he didn't want to leave Midoriya waiting either and once he felt like his thought were more in order he kisses the top of his head. 

"I want you to fuck me, but, ah... I'm not entirely sure the best way," Toshinori admitted. That got a slightly strained chuckle. 

"I think I know a way, just tell me if anything hurts or doesn't feel right?" Izuku urged him up and then lay back for him, wings spread to either side as he urged Toshinori on top of him. Toshinori settled over him, seeing what he was getting at immediately and pressing down against him with a moan. Like this he could feel that Midoriya was just as slick and eager as he rocked up against him. It was almost too much so soon after coming, oversensitive as he was. But there wasn't any pressure on his belly and his back didn't hurt and he wasn't about to complain. 

Toshinori could feel Midoriya's tail curling against his and he let his own wrap around it, holding tight as Midoriya rocked up against him. That was normal enough, but he wasn't expecting the hand on his belly, Midoriya stroking over it shakily even as he moved against him.

"Mine..." It was a soft growl, possessive enough to make Toshinori shiver as Midoriya rocked more frantically against him and Toshinori met the movements with his own, almost too much to stand. Then Midoriya was gasping, hips jerking up and pressing close. 

Toshinori flared his wings out, nearly yelling as he was filled. It was perfect and he could feel his wings trembling as he braced himself against Midoriya chest, looking down at his perfect smile



Izuku stroked slowly over All Might's wings, watching him sleep. He still couldn't believe it, it felt like he'd close his eyes and when he opened them again he'd be gone and it would all have been a dream. 

He'd watched All Might after their chance encounter in his office, seen as he started wearing baggier clothing that didn't quite hide the growing bump in his middle. He'd wondered and hoped and wanted so badly to ask him. He felt like a coward, but he couldn't stand the thought of All Might denying it, or telling him he'd been with another. He'd never let himself hope he might be able to have him like this.

He touched slowly over long golden horns, getting a happy sleeping sigh, smiling as he watched him. All Might was truly gorgeous, where most dragons had two of three colors in their scales, All Might had red, blue, and white patterned together and accented with the metallic gold that marked him as an omega. It made him especially striking and now he could touch and admire as much as he wanted. 

There would be more to do to get ready for the dragonette. Their dragonette. But for the moment he could enjoy having All Might all to himself. 

"You're awake already?" All Might's voice was rough with sleep, but he sounded amused rather than annoyed and Izuku leaned in to kiss his forehead. 

"Yes, I didn't mean to wake you up." Izuku settled back close, affectionately covering as much of All Might as he could with a wing. 

"It's a good way to wake up, I think I could get used to this," All Might said, settling under his wing with a content sigh.

"I hope so." Izuku relaxed, ducking his head close and closing his eyes, listening to him breathe. He had everything he could possibly want right there.
