your heart to guard; my soul to scorch

Summary:

Hawks didn’t realize his unique predicament until he was weeks deep into his undercover assignment in Deika City, surrounded by those he cannot afford to trust or rely on, and too committed to pull out from his purpose. Living in a den of snakes, his words and activities monitored, Hawks can only see his mission to the end.

In the aftermath, he works to mend the broken pieces of his life; his damaged quirk, his reputation, his relationships, his place in the Hero world, and the new life he has created with Endeavor.

Hawks has a future he had never anticipated waiting for him.

Chapter 1: I.

Notes:

Some liberties were taken with Hawks’ physical biology, and I refer to some of his anatomy ambiguously. In this universe, I write male omegas and female alphas to have similar reproductive parts (both, as intersex persons), but roughly different scents and anatomy that is unique to each person. This is still mpreg with alpha/beta/omega dynamics, so if that’s not your jam, please pass.

** Please read the tags and consider the rating. This chapter is primarily smut with language like knotting, slick, slight stomach bulging, scenting, etc. Hawks also has a reproductive implant to stop conception, but later on finds out it is defective.
Also, I wrote this with the implication that Enji and Rei are divorced, and Rei is 100% living her own best life with that hefty alimony.

(See the end of the chapter for more notes.)

Chapter Text

Hawks knew he had put off his heat for far too long.

He could easily justify the reasoning, coming to terms with his own lack of personal care when he had stared at his haggard state in the restaurant bathroom mirror.

Life had been a hectic affair as of late. (Though really, it had been for the last few months.)

Being the Number Two hero, managing his own hero agency, going on countless patrols throughout the day, filling out paperwork, making his PR agent happy with extra publicity and marketing gigs while also performing the expectations of the Public Safety Commission was like a continuous line of juggling fine dishware that multiplied over and over, just waiting for him to misstep.

This also didn’t begin to cover the pressures of infiltrating the League of Villains as a double agent with whatever beck and call Dabi had him on to prove himself.

There just wasn’t a lot of time for himself, and Hawks wished just how much his words had hung true to Endeavor about there actually being some time to kill.

Well, now he essentially, partially, got some of his wish granted, thanks to his own lack of foresight.

Hawks had ignored the malaise and tell-tale cramps that hinted at what was to come. He took painkillers, upped his scent blocking cologne, and ignored the revenge his body was preparing for after he had skipped out on his last two heats with a near unhealthy dose of heat suppressants and meds.

Miruko called him out on it that evening while she sat across from him at their favorite nondescript food joint. She pointed a chicken drumstick at him accusingly.

“Please tell me you’re taking time off to address your heat, or so spirits help me I will put you out of commission myself.” Her eyes were keen and Hawks knew her statement wasn’t just a vague threat. She meant it.

Hawks shrugged. He knew he couldn’t skip another heat after he had forcefully pumped his body the last two times so that he could avoid it. The commission had already berated him, even though the last few times had been done for the sake of keeping himself on the field. This time, there was no avoiding it. His body ached in ways he hadn’t experienced in years, and he hated it all the more for it. Even his wings were sore and oil glands inflamed with excess need to groom and look presentable for a possible ‘mate.’

“I had to pick up some heat aids this afternoon before this shit show begins.” Hawks rubbed at his neck, where the scent blockers were still making a valiant effort to mask his pre-heat pheromones. No one would ever say anything about it, not wanting to be impolite and intrusive, but Miruko was one of his few friends and showed legitimate concern for his health.

She was also an omega, and knew the more annoying details that came with it intimately.

Hawks continued. “And I took three days off from the office already. So yes, I have come to some of my right senses. I’m still going to do some paperwork from home, though.”

Miruko seemed somewhat placated. “Well, that’s something, then. Are you going to have your boyfriend or whatever come help you?”

Hawks snorted. “He isn’t my boyfriend.”

“Oh, excuse me- Is your Number One going to take care of you?”

He bit into his breaded chicken thigh and chewed, purposely making her wait.

He swallowed bitterly. “He declined my offer.”

Miruko blinked. “Seriously? Top alpha like him doesn’t want to help a hot omega through a heat? I thought he’d be all over you since he’s on the market.”

Todoroki Enji had made his separation and divorce public a mere few weeks prior after everything had been finalized. It had been all over the tabloids when Endeavor’s PR agent released the statement, but had fizzled up after the paparazzi couldn’t find any new romantic links for Japan’s top hero. Enji’s statement had been clear that he would be ‘focusing on his family and career’, even though he and Hawks had been doing much more than just hero teamwork for the better part of a few weeks.

It wasn’t necessarily new between them, but they had hit a comfortable stride of not putting labels on their intimate affairs.

Though Hawks was certainly all in and had a few endearments in mind.

“He’s busy and tirelessly practical.” Hawks lamented. “He’s on a case and has interns right now. One of the interns is his son, and I’m not sure Enji is ready to admit he’s taking time off to shack up with me.”

“A wasted opportunity.”

“It’ll be worth it when it happens. If it happens.” The winged hero had often daydreamed how perfect Enji would be in an induced heat rut where all his fantasies of getting manhandled could come true.

Miruko chugged the rest of her beer and eyed him critically. Her voice went more hushed, even though they were in their own private room. “He’s knotted you though, hasn’t he?”

Hawks wasn’t one to get embarrassed, especially with his friend, but his cheeks reddened slightly. “Nope.” He replied with a firm pop of the last syllable.

Miruko hummed. “That’s disappointing. He worried he’s going to accidentally claim you in some post-nut haze?”

“I don’t fucking know. Maybe? His knot is pretty big, so maybe he’s worried he’ll break me?” Hawks rested his chin in his hand. “He’s a complicated guy, but I’m enjoying the ride.”

“I’m sure you are, but maybe you deserve someone more available.”

“As if I have time for an actual relationship?”

Miruko snorted. “I know a few heroes who would be glad to have your number. In case you ever reconsider, or want someone to share your heat with.”

“I am not taking your leftover lovers.”

“Suit yourself!” Miruko ordered another beer and Hawks, happy to have someone to pass the time with and laugh freely and openly to, made a point to stay well past his pleasant buzz.

Hawks’ social circle was big, but it was an empty parade of acquaintances and peer-to-peer engagements. The people he actually felt truly close to could be counted on one hand, and even that was a stretch.

It was fair strategy to keep his cards close to him when anyone could be peaking over his shoulder, looking for a way to dismantle everything he had built up until this point.

Miruko was one of the few safe zones he had.

They stayed for a few more hours eating, drinking, and spurring one another on in conversation. They stumbled out of the bar well past a respectable time and ended up calling a cab when Hawks realized he was too drunk to fly, and wouldn’t be making that mistake again after he had ran into a billboard and almost clipped a power line the last time he tried to fly inebriated.

Hawks, in his own silent fit of defiance to get some time to himself, turned his burner phone off.

Hawks knew he should’ve drank more water, or at the very least less alcohol, but he had enjoyed the rare late evening. He woke up in a sheen of sweat and a fiery, insistent desperation between his legs that was too annoying and pulsating to ignore. He was hungover and in heat, which was a terrible combination, but he had little regrets.

It was average for a healthy omega to have a heat every three months, but Hawks had taken heavy prescriptions for the last 8-9 months to try and skip his body’s natural rhythm.

Now, his body was more than making up for going so long without taking time to rest or get through a heat properly to allow him a reset. There were still safe ways to lessen a heat with medications, but Hawks had abused the science so that he could stay on the work force as long as he possibly could and build up his agency and brand.

He would’ve skipped this heat as well, side effects be damned, but Enji’s relatively new presence in his life made sure his hormones and pheromones were making a mad rush to control his better senses.

Hawks ran a hand through his slightly damp hair and groaned at the misfortune of it all.

He got off with his hand just to sate his erection and provide enough relief for him to eventually tumble out of his bed and saunter towards the shower. On his dresser, he took the doctor approved prescription medicine to at least alleviate any discomfort, and downed the rest of a half full bottle of water that tasted slightly stagnant.

He showered, ate some slightly greasy leftovers from two nights ago, and passed out on his bed again for most of the morning.

Without a partner there to really stir his interest, his body only needed a few rounds of haphazard stimulation or a decent simulated knot plug to keep the discomfort away. Mostly, he was just fatigued and content to sleep and cuddle into his blankets most of the day.

Between rounds of sleeping and masturbating, he groggily watched garbage television on his flat-screen TV while huddled in his mountain of blankets.

One blanket in particular was from Enji’s private apartment above his headquarters. He had pilfered it the last time they had hooked up, shoving it deep into his messenger bag with the express purpose of burying his face in the alpha’s delicious musky scent.

He had also stolen one of Enji’s shirts and wore it with two slashes in the back to accommodate his wings. The shirt smelled of the older hero, which was of little comfort. He wasn’t a complete incomprehensible mess, but he was sexually frustrated and annoyed.

A simulated knot toy or a random hook-up wouldn’t do when he only had eyes for him.

*

*

Enji eventually texted him in the evening, presumably when he had a few moments to himself to check his phone and the few messages Hawks had sent him.

>>Endeavor: Did you receive my package?

Hawks blinked and stared at the words for a good few seconds, brow knit in utter confusion. At first, he thought of Enji’s package, the one he desperately wanted right now, between his legs, inside of his slick soaked hole that tightened at the thought of Enji’s knot teasing at his rim.

<<Hawks: I would like to.

Hawks watched the ‘. . .’ below the chat appear and disappear a few times over.

He laughed to himself.

He hoped he had enticed him, even if it was just a little. Hawks took a quick selfie of his rose-tinged cheeks, lust coated eyes, and lazy smile with a peace sign. He was still obviously wearing Enji’s shirt where the collar gaped at his front.

After he sent the photo, the ominous dots disappeared and Enji’s name appeared on his screen.

Hawks answered with a smile so big, it stung his cheeks. “Hey, hot stuff! Please tell me you’re right outside my door and ready to-”

“Go to your door, Hawks.” The older man interrupted on the other end.

The winged hero giddily pulled himself away from his bed and nearly slipped on the cool flooring. He steadied his balance, wings unfurling slightly. “I miss you.” Hawks chirped to make up for the stumbling ruckus Enji no doubt heard.

“Hm, I’m sure you do.” Enji’s voice held a tinge of amusement. “Now open your damn door.”

Hawks’ heart was beating rapidly and his betrayer of a body took that excitement in overdrive. He felt went and sticky between his thighs, but ignored it in favor of attempting to compose himself.

He unlocked his door and-

there was-

a box.

Hawks stared down at the medium-sized, nondescript brown box sitting innocently on his doorstep. “Oh.” There was some disappointment, but it gave way to curiosity. After all, Enji must have sent him something, which meant he was thinking of him. He was somewhat pleased, so long as it wasn’t paperwork. “Please tell me you’re inside the box.”

“That’s definitely it.” Enji replied sarcastically.

“This is very romantic of you, to send me stuff.” Hawks smirked. “What a good alpha, wanting to take care of me while he’s away! Naughty though, since I got very wet at the thought of you at my door, waiting to fuck me. Are you hiding around the corner?” He peaked out into the quiet, desolate hall.

Enji didn’t reply immediately. Hawks could hear him taking a seat on the other line. “Just...take it inside, Keigo.”

Hawks melted at the use of his real name.

He followed instructions and took the brown box inside and to his room. He planted it amid the nest of blankets and opened the tape off with some sharpened feathers. Inside was red and white tissue paper that he pulled apart eagerly.

He put his phone on speaker in order to pull the rest of the contents out.

Hawks had already purchased some basic heat aids- protein bars, electrolyte drinks, vitamins, a cooling pad, and some snacks, but Enji had also thought along the same lines.

He had gifted him an array of higher grade heat aid products from a well-known, exclusive company that specialized in products for ruts and heats. Inside the box were special snack and drink items, as well as some soft mini towels for clean-up, expensive bed sheets that made his chest rumble in approval at their high thread count, and some lush bath bombs for him to soak in. Further down, he gasped.

“Did you seriously-?”

“You have the salary to indulge in nicer things, but you don’t seem to take the time to care for yourself. You should do things properly, so you can work efficiently.”

“Well, I have you for that now, don’t I? Please tell me this is a mold of your cock.” Hawks teased while he held up the weighty, synthetic skin knotting dildo in his hand. Smaller than Enji, but definitely better than the one he had. He considered the girth of it and sighed, pleased.

“No, but it had top reviews.”

The thought that Enji had taken the time to actively buy him a sex toy and heat aid products from some fancy-ass online store made Hawks swoon. He laughed, feeling eagerly pleased that even though Enji wasn’t there with him, he was attempting to take care of him.

There were a few other personal items in the box, but Hawks had already zero-ed in on the hefty sex toy. “Maybe I should test it out then? I’m dripping for you, you know.”

“I wouldn’t be opposed to hearing what you think.”

Hawks’ breath caught and fluttered in his lungs while his heartbeat quickened.

He laid back.

They’d done phone sex a small handful of times, since distance and time were a chore, but this was new.

“Have you been thinking about me all day?” Hawks questioned teasingly. “Have you been wondering how wet I get, how unsatisfied I must be without you here?”

Enji cleared his voice. “It crossed my mind here and there.”

Hawks licked his lips and laid himself back against his pile of pillows. Enji must’ve been thinking of him a whole lot more than he let on, since he had clearly taken the effort to express 1-day mail him such a generous care package.

“Such a good alpha, wanting to take care of me.” Hawks teased. He rubbed the head of the dildo over his stretched hole and sighed. “I wish I could feel your heat. Wish it was you, splitting me open.” He slowly slid the toy inside a few inches and gasped loudly.

Enji chuckled, dark and low. “In due time, little bird. For now, I would enjoy hearing you appreciate my gifts.”

The omega closed his golden eyes, teeth biting into his lower lip.

He was certainly happy to oblige, especially with the image of Enji sitting at his large work desk, rapt in focused attention to every little sound he made.

Hawks woke up feeling entirely more human by Wednesday morning.

He had extensively preened his feathers the night before after a long soak in his bathtub with the personal care items Enji had sent for him. He had even posted a photo of the vibrantly golden bath bomb fizzling in his bath tub with a few heart and fire emojis.

He had soaked, scrubbed, and felt more re-energized than he had in a long time. Even his feathers were completely full and vibrant red, ready for action.

Clean, polished, and feeling gilded with rejuvenation, Hawks decided to scratch the itch he couldn’t quite reach, his responsibilities set on the back-burner for an additional day. He still felt some of the post-heat stirring in his veins, but it was nothing like what the past two days had entailed.

Enji didn’t even seem wholly surprised when he came back to his office to find Hawks lounging back in his chair, feet up on his desk with a shit eating grin.

“I’m surprised you waited so long to come.” Enji mussed. He was in his full hero suit, though his flames had been licked away when his eyes settled over the smaller omega taking up space at his desk.

I’m surprised you didn’t drive up to see me.” Hawks countered. “Still a little hurt, actually, even though your box of stuff and the meals you sent every day were a nice gesture.” He placed his gloved hand over his chest in faux hurt.

Enji crossed his arms. “So what was your excuse in getting out of work today?”

“I have today off, actually. Heat ended earlier than I thought, even though it was pretty intense.”

“So you came to pester me, is that it?”

Hawks’ face spread into a lazy smile, his eyes crinkled at the corners. “I wouldn’t waste a moment to come see my favorite hero! I thought I could show him just how much I appreciated the care package and the food deliveries.”

The older hero’s jaw tightened. Hawks knew he was gritting his teeth to hide a pleased smile and was trying his best to appear unaffected by the fact that Hawks had completely skipped out on wearing any scent suppressants. His scent was still warm and inviting.

“I have work to do.”

Hawks flicked a pen off the large, oak wood desk. “Good thing you have sidekicks to fill in for you.”

A bead of sweat fell at the corner of Enji’s temple, his blue eyes fixed on Hawks.

Interesting.

Hawks pulled his legs down from the desk and stood, stretching out and showing off his full wings while his hands smoothed up Enji’s crossed arms. Hawks pulled his own glove off of his right hand with his teeth, exposing the still tender scent gland at his wrist.

Enji’s nostrils flared. He quietly pulled the naked wrist offered up to him so sweetly towards his mouth and licked across the heady scent of the smaller omega. He breathed in the unrestricted scent, and for the first time in decades, thought less of responsibility as more baser instincts to lavish and protect filled his head. He had wanted to be there for Hawks’ full heat after Hawks had invited him, but work was piling up.

“Give me one hour to settle things, then I’ll free up some of my afternoon. Greedy bird.” Enji tsked, dropping the hand away from his lips. He had never been tightly tethered to the wants of his body, though it was a close thing to surrender to Hawks’ charms. The younger hero knew how to press all of his buttons so skillfully, which was a manipulation Enji catalogued away. Hawks was always more than his smiles and his easy words. “Go to my apartment, get something to eat, and wait for me there.”

“You sure you don’t want to just fuck me over your desk? I’m pretty wet right now. Wouldn’t even need any prep.” Hawks pulled Enji’s hand down to his neck where his unmarked mating gland was still slightly swollen below his skintight shirt. “Just a quickie to hold you over?”

It was a tempting offer and Enji seriously considered it for all of five seconds, but he was as Hawks always said; too practical.

“Go upstairs before you stink up my office anymore with your pheromones.” Enji turned his lover around and nudged him purposefully away to give him a move on. “I need to finish a meeting.”

Hawks teasing didn't let up. “Bet I could make you cum in 5 minutes flat.”

Leave.” Enji punctuated with a raised brow, fire licking up his face. “Now. Before I change my mind.”

Enji had changed his mind before, and had dutifully kept his word on it.

Hawks huffed and grabbed his messenger bag from the floor. “One hour! If it goes past, I’m going to come look for you.”

“Such a nuisance.” Enji rolled his eyes and grabbed the packet of folders from his desk.

“Yes, but I’m your nuisance, hot stuff~!” Hawks sing-songed.

Enji slammed his office door closed behind him when he left with heavy footsteps.

*

*

To Hawks’ great surprise (and relief), Enji showed up to his private, fully furnished top-floor apartment a few minutes before the one hour mark. He was still in his hero uniform when he walked through the door and purposefully locked it behind him.

The sound of the lock latching in made Hawks lick his lips in anticipation.

“Did you eat?” He asked by way of greeting.

“Ate some leftover rice and chicken you had in the fridge.” Hawks replied obediently. He turned off the television and raked his eyes over Japan’s top hero appreciatively.

Enji’s nostrils were flaring slightly, though he wasn’t breathing in deeply as a sign of typical etiquette. They’d all been taught in grade school to not judge a person by their scent, or to make it so obvious when they were scenting someone out in public whether it could be avoided or not. It was hard to break that habit in private, where Hawks wanted nothing more than Enji to press against him surround himself with the loud indications that Hawks wanted him deeply.

Enji was still navigating this arrangement, having been used to ignoring most of the more sexual side of his needs after being in a quirk-matched marriage where he and Rei had never exchanged bond bites, or spent heats and ruts together regularly outside of the purpose of having children. Enji was also a Class-A workaholic. Hawks wouldn't have been surprised if the alpha had abused some of the rut avoiding medications or trained/worked himself to exhaustion as an alternate means. It was common for many heroes to take this route, though it was a hushed topic.

Hawks knew the main living room smelled of his sweet post-heat scent and the smug satisfaction he was vibrating on. It wasn't a small gesture that the flame hero was willfully taking some time off to indulge with Hawks. Enji’s deeper alpha scent excited him, and he was anxious to get his hands and mouth all over his partner.

"What did you use as an excuse?" Hawks grinned curiously.

Enji unlaced his boots while in the foyer and set them to the side. It was amazing how flexible the bigger man was as he bent his leg, still standing, one at a time to pull off each boot expertly without swaying to the side. Perfect balance. "As if I need an excuse for my own agency."

Hawks' feathers bristled excitedly. "So did you take the rest of the day off?"

"You ask too many questions." Enji heaved a sigh, then stood at his full height with his hands at his waist.

Hawks could see the gears turning in Enji's head while he considered the omega and what he'd like to do to him. His eyes burned with more than his typical fire; there was desire there, and Hawks basked in the glow of it. Wanting to beat him to the punch, the winged hero laid it out clear. “So, since we have whatever amount of time, Mr. Hot shot, I think you should knot me up good. I’m still slick, and I’ve been aching for you for days. So fuck me with everything you’ve got. Sound good?”

Enji took a solid, deep breath in. His massive chest rose and fell with it. The muscles in the right side of his jaw twitched.

Hawks continued. “I mean, if that's something you want-?”

Yes, but I don’t want it to trigger a rut. Your smell is…” He swallowed, eyes narrowed. “A lot.”

“I’m past the worst of my heat, too.” Which went with saying that Hawks' body had smelled even more inviting just the day before.

“And you still smell like this?” Enji gestured over Hawks’ lithe, strong body. Hawks made a move to wiggle off the couch and come closer, but Enji held out his hand in warning. “I’m going to shower first.”

“Can I join you?”

“No.”

“Can I watch?”

“No!” Enji’s face had reddened a little from both embarrassment and annoyance. “I want you to go to the bedroom and get yourself comfortable.” He ordered. “I’m going to wash off my scent suppressors and do this properly.”

Hawks beamed.

It was difficult to try and stay in one place and follow simple instructions when Hawks knew that the larger alpha was in the next room, naked and wet, rubbing soap suds all over his perfect body to allow his true scent to come through.The temptation to sneak a feather in, to listen in on Enji's big hands rubbing across his muscles was tantalizing.

However, Hawks knew that Enji needed to gather his thoughts and wit about him before they took what was decisively a big step in their relationship. (Partnership? Friend with benefits? Domestic arrangement..? Hawks was tired of trying to put a label on it.)

Hawks was decidedly, a little nervous about it. The excitement outweighed everything else, but he had only taken a few knots in the past and each time was a different experience. Mostly from sex toys and a very small handful of times from an alpha friends-with-benefits deal when he was younger, but he had a lot more invested with Enji.

To start, Enji was big. Not just in status and power, but in pure physique. Some people, especially alphas, were just built like powerhouses like Enji was, but that carried with it a higher probability of harming their sex partners if there wasn’t enough adequate prep and care.

(Which, Enji was always very sage about prep.)

Hawks was also completely unmated, unmarked, and ripe for the taking. Knotting with a viable partner came with a lot of scenting, and the doors opening to a faux-mating where their scents could mix and their bodies adjusted to become extra aware of the other. A run of the mill one night stand wouldn’t have mattered, but he and Enji had been invested now. They were almost at the point of hooking up at least once a week, if not more when time allowed.

There was no denying that something more had grown between them.

Hawks stripped down to his designer black boxer briefs. He pulled back the dark comforter of Enji’s bed and sat at the edge, feet swinging over the sides with nervous energy while he groomed the edges of his larger flight feathers.

He sometimes despised how in the silence, the worries that Enji would eventually reject him and choose to end things still lived freely as a possibility in his brain. He anticipated it a lot at the beginning when they first tumbled into sex, but the older alpha eventually grew soft (tolerable?) on him. Enji remarkably gave in and seemed to enjoy their private time together, even if he didn’t vocalize it.

Perhaps because the nature of their relationship had no expectations, it allowed them to both hang free without tradition or too much thought into what the future held.

Hawks lived in the now, which was second nature.

Enji wasn’t wrong when he teased him and called him greedy. Hawks was very greedy when it came to the things he desperately wanted, and all he wanted to feel was Enji’s attention when the quiet moments and opportunities allowed. Never in the way of work or the end goal, but always weighing in the back of his mind. It was one of the few things he had that was truly just for him, and of his own choice.

“Keigo.”

Hawks perked up from his spot at the use of his real name. Intimate and private between them.

Enji was wearing nothing but a burgundy colored towel from where he stood in the doorway. His sharp blue eyes were appraising him again.

Hawks sat up taller, chest puffed out a little more to show off his body.

“You’re sure you want to do this?” Enji was giving him an out.

Why the fuck would I want an out? Hawks thought to himself incredulously. His eyes roved hungrily all over Enji’s massively built frame. Muscle packed on muscle in perfect architecture of power and strength. His waist was solid, chest covered in a light dusting of body hair. Some of the veins on his biceps and forearm stood out when he flexed to cross his arms.

Enji was the apex of strength. A perfect mate.

He was whom Hawks had wanted all his life...and yet-

“Oh I’m definitely sure." Hawks licked over one of his sharp incisors suggestively. "Now get over here! I have a little surprise for you.” Hawks’ eyes darkened in lust while he reclined back on the bed. Enji approached and towered over him from where he stood. He dropped his towel and Hawks’ breath quivered.

“I took some meds, so no rut.” Enji took Hawks’ hand and guided it down to the base of his cock, where the thickness of his knot was forming. “Though I’ve been affected the moment your scent hit me in my office.”

Hawks knew it would only get bigger, already making Enji’s generous erection look obscene. It had never started growing this big before, but it was a response to all the pheromones Hawks’ body was still giving off from his post-heat.The thicker the knot, the longer they'd be tied together.

Hawks had never taken Enji's knot before, but not for want of trying. Enji typically avoided it, as it meant they would be stuck together for some significant amount of time, and their scents would mix and be more perceptible to others. Both were issues not desired in impromptu office romps and quickies.

Though this time? The winged hero took the new situation as all systems go.

“Are you going to let me feel it raw? Want to fill me with your seed, alpha?” Hawks’ voice was deep, purring and thick with seduction. He took Enji’s free hand and ran it over his abs, up to a pert rosy nipple that was hardened with excitement.

“Is that what you want, little bird?”

Hawks nodded. “I want you to knot me so good, I’ll be feeling you for days.”

Enji’s lips twitched into a slight smirk, eyes narrowed. “How about I taste you first?”

The younger omega was pushed back with a firm, warm hand. Hawks' arms sprawled above his head in a relaxed, wanton pose as he pressed back willingly. His wings unfurled and spread out underneath him, creating a vision of exuberant red and sun-tanned skin with his messy dark blonde hair haloed around his head. Enji was completely enamored, the affection a soft crease of wrinkles under his eyes where he focused keenly on his lover.

He kissed down Hawks’ throat, sucked at the scent glands behind his ears and further down while Hawks squeezed the meat of his shoulders.

Hawks pressed his nose against Enji’s damp, clean hair for a quick moment. He inhaled raw and heady of alpha pheromones. His stomach quivered with the powerful scent, even as Enji kissed and licked his way further down the omega's inviting form.

Enji lavished extra attention to his partner’s sensitive nipples. They had always been an erogenous zone for Hawks, and with the heat of Enji’s tongue rubbing over one pert nub, coaxing it to oversensitivty while his fingers rubbed at the other, it made Hawks sigh heavily and groan while he carded his fingers through Enji’s short hair like a lifeline to keep him tethered to reality.

The alpha’s dark red hair was just getting long enough for Hawks to get a small handful and tug through his calloused fingers. Enji pressed into the touch like a big cat.

The omega looked over the older Hero’s body, down the width of his shoulders to his solid core and muscled back which still glistened with droplets of water. Enji went down to his knees at the edge of the bed and kissed up Hawks’ thigh, pausing only long enough to roll Hawks’ underwear down his legs to be discarded to the side.

Hawks spread his legs warmly without a shred of timidness or modesty. Between his legs was a glint of gold with a red jewel that was pressed against his hole.

Enji's scarred brow rose. “Is this my surprise?”

"Are you surprised?" Hawks snickered. The omega was so turned on, he was leaking around the plug, which was trying valiantly to keep it all in. “Can you believe they haven’t made an Endeavor themed plug yet? You gotta call your merchandise people. Ah!”

Enji tugged gently at the plug, pulling it by an inch and then letting go to watch Hawks’ tight hole pull it back in. He kissed at the juncture of the omega’s hip and leg, moved further in, and licked a fat, warm line from Hawk’s ass up to his taint.

Hawks groaned with the heat and shock of sensation.

Even though it was cold winter outside, Enji made it glow into summer wherever he went. Hawks basked in the warmth and the tongue that traced around the edges of the plug. The older hero kissed at the stretched skin, and while he slowly began to slip the plug from Hawks’ body, his eyes roved over the silken slick that drizzled from his hole. For as uptight as outsiders thought Enji to be, it was a satisfying revelation for Hawks to know intimately how focused and thorough Enji could get when he was really turned on and given adequate time to indulge. Hawks' brain fizzled into relief while the alpha's hot tongue and lips delved into his most sensitive parts enthusiastically.

“I used some lube to get it in, but I didn’t need much.” Hawks chuckled, only a little self-conscious. He knew he looked good above Enji, with his lithe form and his own muscles that had just a hint of softness as he was compact and built for speed, not hard and heavy combat.

Enji discarded the golden plug and raked his eyes over him. “Was that even necessary?” He slipped a thick index finger inside of him, with barely any give. He bent his finger carefully, rubbing the pad of his finger against his lover’s prostate.

“Wanted to be nice and sloppy for you.” Hawks admitted breathily. He draped a toned leg over Enji’s shoulder and pressed the heel of his foot against his back. Enji slipped in a second finger, and Hawks cursed openly, tightening around the sweet intrusion. “Got myself edged really close- could’ve come, but I didn’t. I want to come only on your cock.”

“Hnn, a wise move.” Enji approved. He kissed over his partner’s erection and drew a long lick over the underside.

Hawks undulated his hips and sighed as the fingers moved in tandem, filling him comfortably and stretching him more. He groaned when Enji laved and sucked his erection into his mouth, hollowing his cheeks over the girth of the other hero’s cock. He tongued at the ridged head and pressed his face further down, relaxing his throat enough to take the rest of Hawks’ length.

Fuck, ah!” Hawks cried out when Enji swallowed his dick as far as he could, his meaty fingers setting a more hurried pace inside him to overwhelm his senses. A third finger slipped in, and that was it. He was too worked up from earlier, and Enji was too perceptive to overlook how keyed up his partner was.

Hawks’ toes curled, legs tensed and went to jelly while the orgasm he had been denying himself for the better part of the past hour hit him in full force. Enji pulled off enough to continue to run his tongue over his cock head, taking whatever his lover gave him. He kissed at the omega’s spent cock, sucking the oversensitive head back into his mouth until Hawks whined and tried to push his big head away.

"Too much! Damn." Hawks exhaled noisily.

Enji wiped the corners of his mouth with the back of his thumb when he straightened back up. He wiped his other fingers on his discarded towel.

His cock still hung heavy between his legs.

Hawks’ heart was beating a mile a minute while he came down from his orgasm, only to feel the twitch of arousal when Enji slotted himself between his legs, hovering above him to kiss at the corners of his mouth sweetly. The searing hot kisses spread across his jaw, down his neck. Enji focused in on a spot just below his clavicle and nipped lightly, before sucking a dark mark into the younger hero’s skin at his chest.

The omega was floating in ecstasy, smiling lazily. “Gonna have to mark me a little higher so that everyone will see.”

“We already reek of each other.” Enji pointed out. “Scent blockers won’t be very helpful after this.” He closed the distance and pulled the other hero into a deep kiss.

They kissed languidly for a while, Enji clearly in no hurry even though his body had been left mostly neglected. Hawks enjoyed the push and pull of lips and tongue between them, but there was a more pressing need that needed to be sated; a need that had been sitting warm and heavy inside him for days.

Hawks reached between them with one hand and angled the alpha’s cock towards his slick entrance. He rubbed the head of his alpha’s cock there, urging him forward to where he had been stretched and satisfied just a few moments ago.

Enji didn’t break the kiss. He pushed his hips forward incrementally, his cock slipping inside where Hawks directed it impatiently with his hand. The omega jerked the rest of his length as he began to sink into him up until his knot bumped against the ring of muscle, still too thick for him yet. Hawks was still satisfyingly full and moaned into the kiss.

Hawks pulled away to inhale deeply, his golden eyes fluttering to the back of his head.

“That toy you bought me doesn’t even compare to how you feel.”

Enji was hot, all encompassing, and safe.

Hawks’ mind was blessedly free of anything but where they were in the moment. He wrapped his legs around Enji’s waist and spurred him on, both his hands running through and gripping Enji’s short hair when he began to move his hips.

The smell, the taste, the overwhelming sensation of his alpha giving him undivided attention was all that Hawks’ world consisted of now.

Enji’s pace slowly picked up, his brows furrowed with sweat and concentration. Hawks’ hands roamed over the alpha’s body, finding purchase where he could to get better leverage and push his better senses away to the building lust between them.

Hawks rode against the bigger hero, fingers digging into flesh while he gave into the quickened pace. Their scents mingled, cloying the air with their desire and Hawks’ building heat scent. It was hitting him all over again, now that he had the object of all of his affections between his thighs.

He felt scent-drunk and anxious for completion with Enji deep inside of him. As their bodies joined and responded to each other, the pleasure built into an insurmountable force.

“You want to knot me, big guy? Want to fill me with your seed, huh?” Hawks goaded him on, voice on the edge of desperation to be filled to the brim with the knot pressing against him teasingly. Enji was keeping himself together, but was losing himself the more Hawks encouraged him to, begged him to. “C’mon, give it to me! Harder, Enji!”

The alpha’s body heat had Hawks sweating and near delirious from it. He pushed at Enji’s chest, gasping in fresh air that wasn’t soaked with the heat of Enji’s near intolerable body temperature. The alpha noticed and backed off, keeping to his knees while he fucked into his partner. Enji’s body temperature always rose a few digits when they fucked, but he was still present and mindful not to to burn Hawks.

Though it had happened a few times, when Hawks had pleaded him to.

Anyone who said that an alpha had the power in the relationship was sorely mistaken. The way Enji worshiped Hawks’ body and responded to the omega’s every command and plea in bed made it clear that Enji was completely under his partner’s whims.

A few of Hawks’ larger feathers pushed Enji away and out of his body, aiding him in rearranging their position. He wrestled Enji onto his back and saddled back onto his waist, guiding the head of Enji’s fat cock to pop back into his slick heat. His thighs were wet and sticky from their shared fluids, but he couldn’t be pressed to care when they both had a one-track mind.

Careful-” Enji gasped while Hawks pressed down against Enji’s cock. The huge knot at the base teased and stretched at his hole, way too much with Enji’s already well-endowed body filling him up and bumping through his abdomen.

The “You’re going to hurt yourself!” went left unsaid.

No pain, no gain.’ was how Hawks saw it. He challenged him with a gleam in his eyes, but Enji just barred his teeth in warning.

Hawks had already been thoroughly prepped, and taking Enji’s knot was the pinnacle of his desires; the complete and coveted prize for conquering what his alpha had to give. He would be damned if he didn’t put everything he had into forcing his body to swallow down that knot and quelling the pain with his lover’s molten spend.

Enji’s hands encircled his waist, pressing in and guiding him down. Hawks gasped and moaned while every few thrusts, he inched down just a little bit more, stretched a little more heartily.

The omega could tell the older hero wanted to pull him down those last few inches, and despite all of the mix of their scents and pheromones filling heavy in the room, Enji was keeping some of his measured control to not hurt his smaller partner.

As much as Hawks fantasized about Enji letting loose with him, he also didn’t want to end up on a gossip column for ‘Sex sent me to the ER.’

He knew he had to trust Enji with this, trust that he wasn’t going to cause any undue harm on him when Hawks was being pushed to the absolute limits, but would need to go more.

Enji ran his hand up his abdomen, pressing his palm where he could feel himself moving inside. His eyes flared momentarily with fire, which crackled down his body and nearly burned his omega.

Hawks gasped. “I need-, fuck!! Fuck! Enji- I need-”

He was nearly in frustrated tears with the effort. He was so very close to relief, and his body was impossibly wet and singing with arousal, but the press of the knot was too much. He grit his teeth, whined low when the wetness made him slide.

“You want it, Keigo?” Enji pulled him down with a broad hand at the back of his neck and kissed his sweaty temple. “I’m going to have to be a little rough to get it in.”

Hawks gasped, nodding. “Gods, I want it so bad.”

“You’re sure?” Enji’s voice was abrasive, showing how affected he was.

Hawks had to trust that Enji knew what he was doing with him. “Yes.” He babbled again, knowing his alpha wouldn’t proceed without clear consent. He was hypersensitive and keenly aware of every little stretch, but couldn’t get himself past the plateau.

Enji pulled out of him and rearranged them how he wanted. He propped his shorter lover onto his hands and knees, making use of some of the soft decorative pillows to keep Hawks comfortable. The omega was as comfortable as he could be, the pillows providing some support for him to cling to.

Enji draped himself along his lover’s back and kissed up the blonde’s spine, licking and mouthing at his shoulder. He went further into the right juncture of his neck and shoulder, where Hawks’ mating gland was raised only slightly from the meat of his muscle.

Enji kissed it and bit beside it teasingly with a deep rumble.

Hawks groaned, his hips popping up against the wet slide of Enji’s cock along the cleft of his ass. His wings had flattened to either side of him, submissive, but vibrating with power and anticipation.

“If it gets to be too much, I’ll stop.”

And Hawks knew he would. Trusted Enji completely that he would shirk away his own pleasure in order to keep the younger omega safe and content.

“C’mon big guy, I need you to give it to me good. Fuck me so hard I-” Hawks gasped loudly when Enji breached him. “-can’t talk! Ah!!”

Enji licked his lips, having no right to look so confident and sexy where Hawks couldn’t stare at him as openly as he wanted to. He turned his head, breathing heavy while he watched Enji set a steady but grueling pace. Hawks’ whole body was alight with pleasure, his cock hanging and dripping mercilessly between his legs. Enji took it within his large palm and stroked him.

Cute. Enji thought for a moment while he took in how Hawks pushed his hips back against him desperately and made higher, keening noises as he gasped and moaned.

The alpha zeroed in on where their bodies were joined. Hawks was impossibly wet, his slick causing squelching, wet noises from his ministrations. Enji kept up his pace, his shoulders slightly bent while one hand steadied at Hawks’ waist and the other jerked him off.

Hawks’ whole body quivered, building, while he moaned louder and louder without restraint. Enji had half a mind to wonder if the walls were even sound proof, if the engineers had made his upstairs apartment as private as possible. He had never imagined himself here, with someone he was so captivated with, fucking him mercilessly and wanting to soak up as many of those sounds as possible.

“So good for me.” Enji praised him, picked up his thrusts. “So perfect.”

Hawks’ feathers ruffled, his back tightening in force with his muscles as he came. His body seized into Enji’s grip, his spend spreading across the sheets beneath them. Enji teetered forward, now using both hands to ground his lover’s ass back against him until finally, finally, Hawks’ spent body relaxed enough for him to push in the intense girth of his knot.

Enji came as soon as his knot locked into place. Hawks at first attempted to scramble away, his voice filled with distressed whines from the new, half pleasure-half pain feeling that he wasn’t sure what to do with. He cried out as Enji settled him firmly, using his weight to keep him in place while his hand soothed over his abdomen and his lips kissed him reverently, apologetically.

Holy fuck!” Hawks gasped, shuddering as the knot pulsed against his prostate, forcing him into an inescapable high. His body tightened around the intrusion, then snapped into another low-grade orgasm as he exhaled shakily. Tears formed at the rims of his eyes from oversensitive. “Fuck- Fuck!”

It was almost too much, and Hawks had never felt so full and to his limits before, but it was good. Mind numbing, toe-curling heaven.

Enji licked and mouthed at his mating gland messily. The urge to bite hung hot and heavy between them, and their mixed scents were nothing short of a revelation to how much their bodies melded, but he abstained. He kissed and lightly bit up his partner’s neck while both of his forearms kept him steadily above the smaller hero so that he wouldn’t crush him or hurt his wings.

He rolled his hips experimentally and Hawks whined. He wouldn’t pull out, not wanting to hurt Hawks by overexerting the muscle again with the widest point of his knot, but he tested their connection briefly and earned a sharp hiss and a quick hand pushing down against his ass, keeping him steady.

Hawks shuddered again and Enji groaned as he felt more of his spend leave him.

“Easy.” Enji soothed one hand down his lover’s back. “Relax into it.”

“I am relaxed.” Hawks muttered. He felt truly sated, if not completely overworked. He would be feeling it for days, maybe even weeks to come. He still enjoyed the feeling, and even with the slight pain and discomfort, would be craving this connection again. “Damn, I feel you all over, Enji...I’ve never felt this full.”

The words made Enji’s pride glow. His hand sparked with small embers.

Hawks gasped, held Enji’s hand close to his skin. The slight burn was just on the edge of too much, but it was a grounding sensation.

“You like it?” Enji murmured behind his ear, kissing the mess of golden locks.

“Mmm, yes.” Hawks confessed with a syrupy mumble.

Enji slowly maneuvered them to their sides, their bodies still firmly connected to one another. Hawks gritted his teeth, but was surprised by the gentleness in which the alpha displayed to him. Big, powerful, headstrong Todoroki Enji was grazing his fingertips against his arm and rumbling soft nonsensical words to him, proud of him for taking his knot.

Hawks placed his hand over his abdomen and looked down to the slight bulge distended there. It wasn’t over-dramatic, but it was noticeable. His body was warm and safe in Enji’s firm hold, and Enji traced his hand over Hawks’, keeping them there.

They were stuck together, whether they had been prepared beforehand for this level of intimate intensity or not, but Hawks felt that this was a distinct, new step in their relationship.

Or whatever it was they were doing, he still wasn’t sure and didn’t care enough- so long as he had Enji’s eyes on him, and his body warming him, he was content.
