Chapter Text

Keigo being in rut was something you had been warned about. You had brushed it off, much like you had brushed off all the other warnings you'd been given about the pro. You knew he was a hero, knew he'd have to work long hours, knew that he'd be separated from you for long stretches of time. You knew that you'd have to be okay with no knowing where he was, if he was safe, or when he'd be home.

And, all told, you were more or less accepting of that. It didn't mean you enjoyed it, it did mean you understand that there wasn't a whole lot you could do about it. This was what you had signed up by becoming his wife. He never called you that, calling you instead his mate. You weren't sure what the difference was supposed to be, but it didn't matter. All that mattered was that Keigo called you his. That was all you wanted to be in life.

You were shocked when you stepped inside the apartment you shared with him, arms loaded with paper sacks of groceries, and he was standing there. You nearly dropped your bags, cringing and worried about the eggs you'd just purchased. He was supposed to be on a mission, he wasn't supposed to be back for a few days. You had gone shopping to begin to stock up on his favorites so you could make them when he came home.

“Hey there, dove.” his voice was low and husky, going straight to your core. Sometimes you hated that he had such power over you with just a few words. He had reached out and caught the bags, set them on the counter in the kitchen.

“Keigo! What are you doing here?” you gasped.

“What? You're not happy to see me?” he gave a mock pout, walking closer and closer to you. He seemed different in this moment, larger. Stronger. You stepped back, and another, until your back was against the door. He put up both his arms, caging you in.

“Of course I'm happy to see you, babe. I just wasn't expecting you. It's a surprise. A good surprise,” you added quickly. “But still a surprise.” he leaned into you, pinning you to the door. He pecked kisses you to lips, your cheeks, your neck. He nipped at you here and there, giving out happy little trills as he did so.

Okay, this was new. It wasn't strange for Keigo to indulge in bird like behaviors. Sometimes you liked to tease him for it. He would coo, or whistle. He was attracted to shiny objects. So was that kid from UA that he mentored. You liked to tease them that a villain could get away just by throwing down a handful of new coins or costume jewelry.

But for Keigo to be trilling the way he was, so close to you like this? This was a different. You wrapped your arms around his waist, unsure of what you were supposed to be doing in this situation. He hummed and began to drag you away from the door.

“I want to show you something.”

“And I would love to see it, but I have frozen groceries thawing in those bags.” you sighed.

“They can wait.” he sucked your earlobe between his lips. “I want to show you. Come with me, dove.”

“I just bought those.” you fussed. “And you're going to want your favorite, and then you're going to sulk when I don't have the stuff to make it right away.” you knew he would. He always did when he couldn't have what he wanted right away.

At first you thought it was because he was spoiled. Fortunate son of the Commission, always handed what he wanted. He was wealthy, he was well loved. There wasn't anyone you had ever known who wouldn't have bent over backwards to give him whatever it was he wanted.

But once you had spent some evenings with him, dressed in ratty pajamas, curled together on the couch, clutching cups of warm drinks, you knew the truth. You saw the despair he had grown up in. You heard of stories of how they wanted a soldier, not a hero. They wanted a robot they could program to follow every command.

Instead, there was Keigo.

It was all you could do now not to bend over backwards and give him everything he wanted. He had been so long denied. He had been so often left without. It was almost always simple things he wanted, and he was always so grateful when you were able to give them to him. How could you ever say no?

Well, it looked like you were going to have to say no to him now, but it was only because he wasn't putting you in a position where you could say yes. No matter how badly you wanted. You tried as it was to untangle Keigo's hands from around you.

He made a sound you hadn't heard before, a sharp whistle that made you freeze. It felt like a scolding? You stared at him, unsure what to say. But Keigo looked satisfied and took the opportunity of your confusion to drag you towards the bedroom.

“What the hell is--?” you began. He hushed you with a quick kiss to your lips.

“I know baby, I know. I'll explain everything. But I have to show you now.” he kept dragging you to the bedroom.

Your room had been completed changed. He had moved out the dresser, the television, the nightstands. He had dragged every pillow and blanket in the apartment into the room. You wondered how long it had taken him, actually. You were sort of impressed at his dedication, although you couldn't understand why he had done it.

You realized he had arranged things just so on the California king size bed he had bought. You laughed at first, wondering how you could possibly need that much space. But then you realized that sometimes Keigo liked to spread his wings, and those did take space. Of course he needed all the room. He had even tacked blankets up over the windows, blocking out natural light.

“Oh,” you said, unsure what else you could say.

“Do you like it?” he asked, eager.

“Honey, what—what is it?”

“A nest!” his wings puffed up. “I made you a nest. Do you like it?” he asked again. You blinked a few times and nodded. Honestly, it was a really nice looking nest. You just couldn't think of any reason you'd want to sleep in one.

“It's lovely. But why did you do that? You've never done that before.” you were even more confused. Keigo yanked you into him, letting his wings wrap around you. He nuzzled into your hair and sighed happily.

“Because I'm in rut.”

“In rut? You never told me that was a thing!” you were startled. His hands were all over you now, rubbing any inch of your body he could.

“Because they were hoping if I had my mate by me enough, it wouldn't happen. But, well.” he shrugged. “They kept pulling me away from missions, so here I am.”

“What does it mean, in rut? What does that mean to you?” you demanded.

“Well, babe, you know that I maybe have a few bird like behaviors. So this means that I do things like build you a nest. I want you close to me. I want to touch you all the time. It means that I want to strip you naked and bury my dick inside of you until you're screaming. It makes me want to breed you.” he said it all so casually. You felt your face heating up.

“What if I don't want any of those things?”

“Are you saying that you don't?” he seemed to wilt, like someone had cut his strings. It was always like that with Keigo, you thought. He had such high-highs and low-lows. It was hard to keep him balanced, and you worked on it daily. It was a concentrated effort, and sometimes left you exhausted.

“I do,” you hurried to assure him. “I really do, babe. I guess I was just curious what would happen if I didn't.” Keigo perked back up and kissed you, his tongue pressing at the seam of your lips. You parted them, happy to let him in. His tongue wrestled with yours, leaving you feeling breathless and aching. You whimpered when he parted from you.

“We don't have to worry about what would happen if you didn't want to. Because you obviously do. We won't waste our time, will we?” he was walking you to the nest. “Get in, get in.”

You stepped into the nest and laid down. Immediately, some his feathers were coming to tuck you in, brush your hair back from your face. Confused, you looked at your husband. It almost scared you to see how giddy he was.

“You need to lay down and take a nap. I will go and put the groceries away, I will make something to eat. You're going to need your strength for what's coming.” there was a gleam in his golden eyes you hadn't seen before, one that made you feel a little cold. It was calculating, and more than that, it was hungry.

“What's coming?” you asked. Keigo cooed and leaned down over you, stroking his hand down your face. It never failed to help settle you down when he touched you in such a way. You pressed into him, drinking up the affection.

“You'll see. I don't want to worry you just yet.” he turned and bustled the way. You laid in the nest, surrounded by soft blankets and pillows. You couldn't help but worry just a bit.

***

In about half an hour, Hawks was back with a bowl of food. He stepped into the nest and helped you sit up. He surrounded you by pillows, making sure you were well padded. You expected him to hand you over the bowl. Instead, he used the spoon to construct a bite and hold it to your lips.

“Keigo?”

“It's good, I made it just the way you like it.” he winked at you. You took the bite, chewing and swallowing.

“Yeah, it's good.” you agreed. “But I can feed myself, hon, you don't have to worry about things like this.”

“I kinda do, actually.” he shrugged. “It's part of being rut. It makes me want to take care of you, it makes me want to make sure that your body is in perfect order for having a baby.”

“I'm on birth control.” you blinked, confused.

“Rationally, I understand that. We agreed it was the best idea. Emotionally? My hormones don't give one single solitary fuck. I want to do one thing and one thing only, and that's breed you, baby.”

“Okay,” you said slowly as he spooned another mouthful of food into you.

“And I need you to know that it isn't going to be some kind of gentle love making. I am going to fuck you. I am going to tear you up. You're not going to know what hit you. By the time it's over, you're going to be one filthy mess.” his eyes were gleaming again, and he was leaning closer and closer to you.
“And then I'm going to want to do it all over again.”

“O-oh,” you stammered.

“So if you want to leave for a few days, I totally understand. But you're going to need to do that right about now, because I'm not going to be in control of myself for much longer.” there was something dangerous in his voice, here was a warning there. You were playing with fire by staying with him, but you thought it might be fun to get burned.

“What kind of mate would I be if I left?” you shrugged. Keigo gave you a grin and helped you eat the last of the bowl.

“That is exactly what I was hoping you would say.”

Chapter Text

Keigo didn't want you to take off your own clothes. He insisted on doing it for you. He hadn't been kidding when he said he wasn't going to be gentle. He was so desperate to touch you, to get at your skin, you could hear the seams ripping on your clothes. He threw the tattered remains to the side as you stood there, naked in front of him. You trembled slightly, going to cross your arms over your chest.

“No,” he grabbed your arms, pulling them down to your sides. “I want to look at you.”

“You've seen me before. It's nothing new.” you pointed out.

“I didn't ask for your opinion, did I?” he mused, tapping his chin. “No, don't think I did. I don't need you to talk. I just need you to know that I am going to fuck you.” you squeaked at that. He was never so—harsh before. Hawks was always loving and gentle with you, probably because he was so much bigger than you and well knew what damage he could do if he really wanted to.

Maybe tonight he wanted to do some of the damage, you thought.

“I can smell how turned on you are.” he noted. You noticed then that his pupils were blown wide, and he was laser focused on you. It made you feel shy, made you want to shrink in on yourself. It even made you feel a little afraid.

But you couldn't deny the fact that you were wet between your legs, and you were beginning to ache for him to touch you. No one ever touched you like Keigo, no one ever coaxed your body into orgasm again and again like Keigo.

Before you could respond, feathers were coming, pinning your hands behind your back. You squeaked, surprised. He was lifting you up, throwing you onto the bed. He wrenched your thighs open, groaning when he saw the wetness oozing from your slit.

“Fuck, you're always so ready for me. That's how I know you're the perfect mate. Now we're going to see if your body can keep up with me, too.”

You didn't get the chance to speak again, his face burrowing into your cunt. You cried out, going to reach for him. You loved burying your fingers in his hair. You could admit that you sometimes used it as a way to get him to move just the way you wanted him to, and Keigo always went willingly. Tonight it seemed to be a different story.

This was Keigo's game, and you were simply a pawn.

His tongue slithered sinfully into you, lewd sucking sounds coming from your needy cunt. You moaned, squirming on the bed. His fingers dug into the meat of your thighs, keeping you from being able to move as freely as you wanted.

You glanced down, saw his eyes were laser focused as he ate. His tongue trailed up your slit, swirling around your clit before he latched on to suck. He let go of one thigh, although you got the message that he really didn't want you to move and now was not the time to be testing him. Sometimes he had a lot of fun chasing you, but this was something different, something a little more primal, something that could lead to you really getting hurt if you weren't careful.

That thought really shouldn't have made you gush. You listened to Keigo groan happily, lapping up everything you were giving him. His fingers were moving faster inside of you, twisting a little, looking for something. Before dating him, you had been fairly certain you weren't able to cum from penetration. Normal, you knew that. But then you had met him, and the way that he was able to move his fingers and hips and you knew that you hadn't had someone patient enough, someone who was willing to learn the way your body worked to make it happen for you.

Part of you hated that Keigo knew you so well. He was able to make you cum again and again until you begged for mercy. He was able to make you cum until you cried, pleading with him to stop. And he'd nearly always brush your hair out of your face, whisper how good you were for him, how perfectly you were doing, and that you could give him just one more.

You almost always gave him one more.

“You taste so good.” his voice was muffled by your flesh. “It's all for me. You're all mine.” he flicked his tongue against your clit, moved his fingers against that magic place inside of you until you shouted, cumming on his face. He groaned, making those slurping sounds again. He was determined not to let a single drop go wasted.

You were panting when he was done, wobbling right on the edge of overstimulated. He moved his head, nipping hard at the delicate skin of your thigh until you keened. He moved from between your legs,and if anything, his eyes looked more hungry than when he started.

His feathers were moving again, and you found yourself pinned to the wall, your arms bound above your head. You whimpered, not liking the way that your toes were only skimming the floor. How were his feathers strong enough to move you? Keigo walked slowly towards you, his hand reaching out to cup your face. You leaned into the gentle touch.

“Don't worry, baby.” he sighed. “I'm not going to hurt you in anyway that you don't like.”

Before you could ask what he meant, he was grabbing your legs, holding them up in the air until it was only your back and your arms against the wall. He had pinned you at the perfect height so he could fuck into you from there.

That was the only way to describe what was happening. He was frantically fucking into you, his cock was obviously painfully hard, and you could feel it twitching as soon as it entered you. You sighed, enjoying the sensation of his cock filling you, as you always did. He had joked a few times that your cunt was made for him. Or if it hadn't been, he had carved out the perfect space for his dick, and you were never going to feel as satisfied with anyone else as you did with him.

He took no small amount of pride in that, you thought with a small smile.

But now, Keigo wasn't teasing you. He wasn't putting in his tip and pulling it out slow. He was pounding into you, making you feel almost too full. He was going almost too fast. You didn't even have the chance to try and think of the words to tell him that things were too much. He was gripping your legs so hard, you knew you'd have bruises later.

You wore bruises from Keigo the same way others might wear jewelry. They made you feel cherished, loved. Like you wre there to be admired. A bruise meant that he loved you, and someone loving you was something you wanted to show off to other people.

One of his hands came to your throat, wrapping around it and giving a tiny squeeze. Just enough so you focused your gaze back on him. The smile on his face was feral, caused a thrill to trace down your spine. You whimpered, your pussy squeezing around him, making him groan.

“Trying to make me bust, sweetheart?” he sighed. “You know all the things that make me tick, don't you? But you know, that's not going to be enough tonight. I did warn you.” the feathers holding you fell and you almost screamed, sure he was going to drop you.

But Keigo never would have let you get hurt like that.

His hands were around your hips. You marveled at the fact he was able to walk with his dick still buried inside of you. He stepped into the nest, and reluctantly pulled back from you. You sighed, feeling the emptiness and the ache that it brought.

“You hate that, don't you?” he laughed softly. “My little cock slut. You can never get quite enough. I know sometimes it feels like too much, but if I take it away, you hate it. That's the way I like you, needy and desperate for a good dicking down.”

The mouth on him! You couldn't respond before he was moving your body again. He had laid you on your stomach, and was lifting your hips until you got the message and pulled your legs in towards your chest, arching your back and presenting your ass nicely for him.

“This is a view I could get used to.” he sighed happily. He delivered a few well placed swats, making you jump a little bit, making your hands clutch handfuls of the nest. He rubbed the spots he had abused, as though he were sweetly sorry after. You turned your head to look at him, feeling your breath coming in hot, wet pants.
“Aww, baby. I'm sorry, am I neglecting you a little bit? Need me to get to the point? You'd think you were the one in rut.”

“Please,” you murmured, wriggling your ass, hoping that you could entice him. “Please?”

“That bad? I got you down that bad, baby? Fuck,” he smacked your ass again, laughing at the way your ass jiggled. Without another word, he was sliding back inside of you. There was a faint burn and then relief. You could have melted down into the nest. He reached for you, jerked you upwards against his chest.

You felt helpless, boneless, as he bounced you on his erection. He was moaning in your ear, breathing hard. Before he latched onto your neck, sucked in large bruises. His wings covered the two of you. You were surrounded by him, the smell of him, the feeling of him, the warmth of him. Your whole world had shrank to just Keigo, your world had exploded to just be Keigo.

“Fuck,” you whined out. He laughed, one hand coming to pinch at your nipples, making you whimper and whine.

“Are you starting to get desperate, pretty? Just how much do you need before I can finally wear your ass out, huh?” he nipped at your shoulder. The sting, the feeling of his cock inside of you, the pounding of his heart against your back, it was all just enough to tip you over the edge. You were cumming, spasming around him, unable to say a word about it, feeling the wetness pouring from you.
“Goddamn, you—I can't---MINE!” he growled, his teeth sinking into you again, his fingers clutching you so desperately you thought you would lose your mind. You mewled and fell silent as he pumped his hot cum into you. He was close to drawing blood, but something told you at this moment he was not able to hear what you said, he was not able to understand that he could hurt you.

And he had been right when he spoke earlier. He never hurt you in anyway that you didn't like.

When he was done, when you could feel how sloppy your pussy was, he slowly laid the two of you down in the nest. He left one wing around you, keeping you against him. Keigo was often possessive, you thought, although you typically attributed it to his abandonment issues he most certainly was never going to discuss in therapy.

“Are you with me?” you wheezed out when you heard his breath return to normal.

“Yeah,” he murmured. “I'm good for now. I won't be again in a little while. What can I get you? Water?” he was eager to bring you something, anything to prove he could still take care of you. You shook your head, pressing your back into him.

“Hold me, Keigo.” you murmured. He was always happy to do whatever you wanted in these quiet moments after he had just annihilated your vagina. You were dripping with his cum, but he held you like you were precious and fragile.
“Part of me thought you'd want me to lay eggs or something.”

“Well,” he gave a rueful little laugh. “I did maybe look into an ovipositor. If you're interested...”

“I don't think I'm ready to go down that road yet.” you said honestly. “But I really am warming up the idea of a perfect nest built for me by my mate.”

Keigo puffed up behind you, preening a little bit. You laughed softly, enjoying that you could make him so happy with just a few words.

“You should rest.” he said softly. “Because once I've rested a little, I'm going to be right back to it.”

You couldn't wait.
