Summary: Kat is a dragon going through an unexpected heat and Dallas is a knight who can help. A holy knight can not abandon his duty after all. Note: I might make more in this AU but this is all for now. Thanks to my wife for the beta read. you can find art on this au here under the tag: AUs

He had been left. When the knights barged in and tried to hold her back before taking her sister from the tower, she had thrown him into the cavern. Kat didn't even remember when she did it. There was a lot of fire, a lot of screams and a lot of knights being boiled alive in their suits from her purple flame. In the end, they had taken her sister. And she was stuck there alone.

She had cried for hours and wailed for days. It was only after that she noticed things moving around that she learned she wasn't. And then one day she noticed smoke. And she found him trying to eat a rat.

She should have killed him. But she didn't.

Being alone in that cave had made her crazy and she offered him the tower. Her sister wasn't coming back no matter how much hope she would. He declined. He told her he didn't deserve something like that. So, he stayed in the cave. With her.

He spoke her language. It wasn't very good and he sounded like a formal old man but the more he talked to her the more she started to welcome the sound of a voice that wasn't her own. The more she would talk back and the closer his encampment came to her living area. Until eventually they slept on the same pile of pillows and blankets together.

He didn't wear his armor. It had been cracked and damaged from being thrown. He wore just cotton clothes. Only his sword, his Bible, his cross and his prayers remained of his old life. He never used his sword but his tiny gold cross would twinkle in the sunlight when he fetched water. She would stare at it, but never make any move to take it. Other than that, he would pray and read.

He did a lot of that actually. Pray. But lately he had been doing it alot more. At first it had been normal occurrences. He would pray before eating; he would pray before sleeping. But now it was more. Anytime she was near she could hear him mumble something under his breath in that strange language.

"Why do you pray so much?" Kat asked, watching him from the shade.

"Hm?" Dallas said, trying to get a secure knot. He has been trying to build a fishing pole as summer was around the corner.

"Praying. You pray a lot. Is it another one of your holidays?" she asked. She liked the first one he showed her in the winter. He had gone into the forest and came back with a large tree. They got to decorate the tree with the gold she hoarded and told stories. It was nice and fun. She wondered if another thing like that was coming.

He paused. He looked confused before his face became as red as his burn mark." Oh... oh I am sorry I did not know I was saying it so loud." He said as he tried to go back to casually building his fishing rod."No, there is no holiday that I know of..."

"So then why are you praying?" She asked again, sitting up.

He look like he didn't know how to answer that. Kat often asked him many questions about humans, and this wasn't anything different other than his excessive embarrassment.

"For.... strength," he finally said, intensely focusing on his work. She could still see the red on his ears even with him turning to face the water.

"Strength for what?" she tilted her head. He was human, how strong did he expect to be? Was it one of those weird things from that book he constantly reread?

"Strength to keep my principles..." Dallas finally responded. Yeah definitely that weird book. She hated that thing. She couldn't even read it since it was in the language of Latin or whatever he had said. She only knew her tongue and only understood him when he spoke it. She had no clue what English even was. A Lot of the other books she had hoarded were that.

She couldn't read those either. But he could. He would read to her sometimes, however he would then suggest she should learn herself which immediately ended any moment they would have.

Why should she speak english. She only knew one human that wasn't her sister. And her sister spoke dragon anyways!

"Hmm." She said before changing the subject,"do you really think you're going to catch anything with that?"

He relaxed, chuckling a little."Oh just you wait."

She didn't bring it up after that. It wasn't until later that night that it seemed to come back. She had finished eating, grateful he caught so much as she didn't want to help him. It was his turn that night to provide the food.

Kat stretched her arms out letting her back pop and snap. It was with her arms still in the air, that she heard the mumbling. His hands were clasped as he mumbled his prayer. How odd.

He didn't pray after they ate.

"Are you praying for strength again?" she asked, repeating what he said.

His face was red when he was caught."I...." he swallowed,"I apologize."

She raised an eyebrow."About having strength?" She asked, teasing.

He sighed."About not having enough..." he said with resignation,"and I pray to have more of it."

Kat really didn't understand what he meant. She couldn't tell if it was a culture barrier or he was talking nonsense. With him it could go either way."Is there a reason that you need so much strength?"

"So that I may stay with you."

That alarmed her slightly. She didn't want him to go. She had grown very fond of him. More than fond, as she enjoyed his conversations much more than other dragons. She enjoyed it more than even talking with her sister."Why would you need strength to stay with me? I'm strong already." She kept the panic from her voice as her tail twitched.

Dallas smiled at her and the softness made her heart beat. It was different from the stress. It seemed to calm her in a way she didn't know how to explain but suddenly made her very aware of him.

"I know you are," his smile fell slightly,"it's not that kind of strength."

"Then what kind?" she said sitting up, she still towered over him when they sat,"I mean I can help."

His face grew dangerously red, like when they had been by the river. It only confused her more."I-i do not think that would be wise," he stumbled over his words in a way Kat hadn't heard in a long time.

When she found him in the cave, alone he didn't go near her. He kept his space. Even when they spoke at first, it had just been the echo of his voice. When they stood face to face, at first he couldn't say much without stumbling over his words with a red face. It was reminiscent of what was happening now.

She leaned closer."But I want for you to stay," she said, almost leaning on him,"please let me help."

He put up hands immediately, as if to put space between them. He had never done that before. Kat blinked, a little startled. She pulled back.

"I..... I will.... I will be fine. I do not have plans to leave you," he said finally."It will surely pass."

She could see how much he was sweating and she was unsure of why. Maybe he was sick? Did he not want to get her sick? Maybe she should see if she could find medicine. She would help. They were friends. She leaned back nodding in thought.

The next couple of days she looked for the herbs she needed. She didn't tell him, of course, so everyday she came back with an elaborate excuse of getting lost hiding a bag poorly behind her back. He didn't seem to believe her, but he didn't pry. Something she appreciated as she didn't know why she was so focused on this. He hadn't asked her to do it and yet she still felt compelled to do so. Having to explain these actions would just embarrass her. Just thinking about it already did.

She walked a little far to pry bark from a willow tree. The wind flowed and she could feel the heat of the spring ending. She loved this temperature. Dragons usually did. It was their season, and she felt a small ping of excitement as she would be able to show him her holidays this time. The thought of showing him the summer solace and teaching him the dance made her face flush. She shook her head attempting to get the heat in her cheeks to go away.

She moved to pick another piece when she noticed the heat didn't go away at all.

In fact, Kat could feel herself starting to sweat and her legs starting to feel weak. She didn't know where the oncoming wave of arousal came from but she was immediately crippled by it. It hit her right at the bottom of her stomach where it throbbed.

Her eyes grew large as she started to realize. It's the end of spring.

She completely forgot about the mating season. She never forgets something like this. It had been a very complicated year that she didn't even notice it snuck up on her. She would have just stayed home. She was only out here because of medication. Had she been that distracted?

Kat whined as the throbbing between her legs cried for attention interrupting any thought she had. She needed to get back to her cave. She would be fine. She was fine every year, but she didn't like when other dragonfolk came sniffing around.

She made sure the bark was in her satchel as she stumbled her way home. At this point she would need it more anyways.

She walked along the river. Taking moments to stop and dab herself with water as she walked. She needed anything to at least keep her mind focused. The closer she got home the weaker she became. Gods, she hated this.

She could hear the sound of movement in the water before she turned the bend and there he was. His cotton pants rolled up and his shirt removed as he used his new fishing pole. She had looked at him every day for almost a year, but now her eyes focused on everything.

The small scars that littered his chest and arms, the burn mark she created on his back, his muscle flexing and relaxing as he threw the line, the hair that naturally grew all the way down to where his pants cut off, and the small specks of water that dotted his entire frame.

She was so fixated she didn't even realize she had stepped to the water and walked towards him. It wasn't until he looked up and smiled that she finally sucked in air. Her nostrils were filled with his smell, his scent accompanied with light sweat and freshwater.

Kat probably looked deranged as she closed in on him, as his smile turned to one of confusion.

"Are you alright?"

She could hear his voice crystal clear, like every other sound was unrecognizable noise. But she couldn't understand it. All it did was draw her closer. Her head came down, smelling the top of his head.

He smelled even better up close. She sighed longingly, leaning against him as the wetness between her legs started to leak with want.

"You are very hot!" She could feel a hand on her arm trying to guide her out the water."Are you sick? Were you sitting in the sun too long?"

She felt herself shake her head. Doing the best she could she pulled herself away, stumbling in the water. She couldn't do this. Could she even mate with a human? The thought immediately confirmed she wanted to try. It took everything just to focus on keeping her eyes open. She felt herself shaking as she landed on her knees. He was by her side in an instant and she needed him to get away.

"S-stop," she whined trying to push him away,"get away from me."

"Of course not. You seem sick. Are you sick?" He said a bit frantically as he moved to put her arm over his shoulder. His touch burned as she yearned for more. She pulled away from him.

"I can't; I can't," she sobbed. She just needed one. Just a single time and then her head will be clear enough. It was overwhelming. That's all she could think about was his scent, his touch, his voice; everything. She wanted nothing more than to feel him inside of her and her body ached for it."I'm sorry," she sobbed her only warning,"please look away."

She didn't seem to wait as her hand plunged under loincloth and she felt the wetness that she knew was there. She used her hand to prop herself up as her other hand shook when she rubbed her clit. It felt so good just to have a relief from the pressure. It had started to become almost painful until she felt the stimulation. She rubbed only for a bit, practically humping the air before her fingers found a way in. She cried at the sensation, whining his name without even thinking. She pumped her finger eagerly. The only sound coming from her was moaning and the water splashing as she moved her hips.

She wished her finger was him. Her body craved him and the need to be bred. She kept calling his name like a mantra as though it would get him to come over. There was only a small shred of self awareness at how she was begging for it. That overwhelming shame ran down her spine adding to her arousal as she continued to cry for him.

Then she came. She did her best to rub against her palm as she felt the contraction around her fingers. It wasn't what her brain wanted and it was too quick to be completely satisfying but it at least let the overwhelming need pull back. She pulled her fingers out with a sick squish before sitting back on her knees.

She panted. Gods. She looked over at him and she only saw his back. He had looked away like she asked but he didn't leave her. She was grateful for his presence and at the same time incredibly mortified. That shame from before easily took over.

"S-Sorry," she said, wanting to cover her red face and maybe drown actually. Why did she say his name?"I didn't mean to say--"

"You are in heat." He said confirming rather than asking.

Kat swallowed."Yeah..." she confessed before quickly continuing,"but I've been through many heats alone. I just forgot how soon spring was ending. I just need to get home and I'll be okay on my own."

There was a brief pause between them. She felt the need to apologize again. She shouldn't have said his name while doing that and she should have been stronger. Mating usually happens out in the open, mostly out of superstition that the sun would help bless you with a baby. But Humans were different then dragons. He never propositioned her like that. She felt her thoughts delving further into shame when he interrupted it.

"Do you need me to help you?" He said.

Her eyes bore holes in the back of his head. His ears were red.

"Do you know what you are asking?" She asked unsure how she would have to reword it if he didn't. She was hoping he didn't misspeak, but she couldn't tell if that was her head thinking that or the throbbing between her legs. He spoke her language but he wasn't perfect. It could have meant something else in English.

"I am asking you to let me help you with your heat."

Her body immediately begged for it. She couldn't place when she liked him but her body couldn't deny it. They would need to talk about this, they would need to figure out what this meant but all she wanted was him.

"Are you sure?" she asked not sure what to even say that wasn't just to jump on top of him.

He turned slowly and she could see the slight tent that had formed in his pants. Heat immediately crept up her spin and down her stomach. She just came but she tingled with anticipation as her heart hammered in her chest.

He walked up to her. While she sat they were the same height, give or take a few inches. His hand came up and cupped her cheek, and she immediately leaned into the warmth he had."If you will have me..." he said in her language."Yes."

It was almost instant that she leaned forward to kiss him. It was a little awkward. She had only ever been with dragons, never something as delicate as a human. But then again he wasn't delicate; he constantly put himself in wreckless situations. Trying to fight her when they met was one of them. This was just another one.

She bit his lip to his chin, not trying to leave scars. Even though every instinct was telling her to leave his body riddled with bite marks. She could feel his hand pull her top down. His hands weren't confident, even hesitant, but they sure were diligent as she felt him play with the iron bars in her nipples.

The pull wasn't hard and he moved to groping and molding her breasts under his hands when she let out a whine. They kissed sloppily. She mewled against his mouth encouraging him. He tasted unreasonably good. It was probably the heat that was working back up but she could feel herself drip down her legs just from him playing with her nipples. He moved his hand and twisted her slightly harder than expected. Kat pulled off him with a gasp.

"Sorry" he breathed out against her skin. His breath was warm. His touch was warm. Everything felt so warm.

She shook her head, swallowing hard. She must have been drooling. Dragons don't normally do it this way. She wasn't against it. She just didn't know what he was doing.

"Why are you playing," she said as she could feel him kiss her neck. It was making her squirm."Just put it in."

He laughed against her and she could feel him continue to play with her nipples. It felt so good but his laughter made her hot.

"I want to make you feel good," he said as he continued to kiss her.

"I-!" She yelped at being bitten on the neck."I already feel good," she continued impatiently, her tail starting to splash the water.

Each pull, twist and bite, her body twitched in reaction. He was so insistent it was hard for her to keep up.

"Please," she begged, a hand that held onto him moved to touch herself. She leaned back, opening her legs so he would be pulled between them. They were still partial in the water but she didn't really care. He followed her down, hands stumbling a bit.

They moved to her hips and Kat immediately attempted to hump him. He didn't look startled but he let out a nervous laugh.

She was trying to be calm but her brain could only focus on the tent in his pants that was now very close to where she wanted it to be. She pulled aside the flap of her tunic as her hand presented herself, opening her lips for him.

"Dallas," she pleaded,"I need it."

She could see how flustered he was as he stared at her. Looking down even more nervously, he slowly removed his cotton pants.

It was different from a dragon's. No spikes, no knot and completely the same color as his flash save for the redder tip. It twitched as it lay on her lower stomach and her entire body flared. She could see his nervousness increase as she continued to stare at it.

It's not like she hadn't seen it before. They bathed together and during the winter they would sit in the hot springs. She's seen him relieve himself on occasion. But she had never seen it hard before. Each twitch increased her impatience.

"I know it is not very b-"

"Put it in," she interrupted, her tail splashing."I don't care that you're not a dragon," she said before rubbing against him,"put your cock in me, Dallas."

His face exploded red and he swallowed. He looked like his words were stuck in his throat but he nodded dutifully. She watched as he lined himself up. It took a moment as she kept wiggling impatiently. He slowly pushed in, but from how wet she was it was an easy glide. Wet enough that it spread to his thighs and coated his public hair.

"Holy on high," she could hear him mumbling under his breath as it disappeared inside of her. He was saying things, things in English she just couldn't understand, but she didn't care. He was finally in her. It was like a piece of her had been missing and he just interlocked the last one. She moaned a little as his hips grinded against her experimentally.

It felt so good.

"Kat, can I-"

"Fuck me."

"Yes ma'am."

Her body reacted positively to the honorific, but she didn't have time to dwell on it before he pulled out slightly and started thrusting into her.

She moaned uncontrollably as each pump gave her a spark of pleasure that radiated down to her toes. He wasn't going that fast but the overwhelming feeling made her writhe under him.

"Hah, AH-! Right there, yes!" she encouraged him and he immediately corrected how he thrusted.

He would whimper but any command she gave he followed, plowing against her sweets spots to the point she saw stars. It wasn't that he was good at sex, she didn't even know how to quantify that. Dallas just listened to anything that made her feel good. If she moaned louder from faster thrusts, he picked up the pace. if she mewled when he grabbed a nipple, he would follow up multiple times.

Whatever she wanted, he gave.

"Gods yes," she moaned out,"AH-! harder."

He lifted a leg over his shoulder as he bent her upward. His hands were firm but she could hear him rambling again and panting. He thrusted downward, right where she wanted it and she cried out.

"You are beautiful. You are the greatest gift I could ever receive" he was drooling, his face covered in sweat, but she could finally understand him."I'll do anything. My goddess, my queen."

The names he was calling her ran a ripple of pleasure up her spin and hit her in the pit of her stomach so hard she almost came from that alone. It was making her head spin. She needed to hear him say it again. But the tingling from her stomach had other plans.

She could barely get it out as she held onto the rock behind her."Dallas, ah-I'm so close," she panted out.

Dallas nodded, almost in a daze as he did exactly as he was told. He took a moment to lift her other leg upward before thrusting his hips at a quicker pace.

Kat cried his name as he pumped in and out of her. It was like she was melting and she could feel her legs tingle as he held them up over his shoulder.

She couldn't control herself when her tail pushed against him, begging him to keep the pace. He seemed to read her mind as he didn't let up, huffing against her chest as her toes started to curl.

"My Kat--!"

She could hear him and she moved to hold onto him. Her arms wrapped around his head, scratching up his back as her body pleaded for more.

"I--I'm going to--!"

"Please!" she cried, her desperation just as loud as she came to her own orgasm. Her tail wrapped around him, she needed more."Breed me! Mark me inside! I want to carry your child!"

She could, of course, hear his whines and curses as his head rested on her chest but she felt it first. Her entire body lit up with a strange mixture of excitement and satisfaction as his hips moved to grind against her, his cum spilling inside of her.

It gave her a second orgasm almost immediately, she could feel herself pulsating around him and her tail kept him rooted inside of her.

She panted as she tried to wait for it to stop. Her body was overjoyed which gave her that time to come down. It was the most satisfying experience she ever had.

"Kat?" He was panting just as hard as he stared up at her.

She looked down at him. He was covered in sweat, from both hers and himself, but he had that silly smile on his face. The same one he had when he was doing things that fascinate him and he would share it with her. But rather than a book or jewelry or a rare insect, it was her.

"You okay?" he said with a sigh against her chest, and she was praying he could not hear how loud her heart was beating.

She nodded, embarrassment starting to work its way up. But when he kissed the center of her chest, it accelerated that feeling. Her legs became limp and he could easily unfold her.

"Is it okay for me to pull out?" He asked softly. He didn't move away from her, only waited patiently. He was acting so kind; it was making her more embarrassed. Dragons don't tend to do that after a mating."I do not know how long... dragons leave it..." he said unsure.

"I--" her voice cracked flushed in embarrassment,"just h-hold on."

Her hand came down between her legs. They worked together as he slowly pulled out and she caught anything that spilled out. She quickly moved out to the water and closer to the grassy side of the riverbank. Only at that point did she let her hand drop and lay back. Her hands came up to her lower stomach in satisfaction. He lay next to her, that same stupid grin made her embarrassed and she turned away to look at the sky to avoid his gaze.

Her heart wouldn't stop beating fast when he did that.

They laid there for a moment, just cooling off but she couldn't believe how nice her body felt. Nicer than any season she had been with a dragon, she felt light on her feet. She smirked to herself as she was about to bring up the honorific name when he interrupted.

"Sorry," he said, she glanced back at him with a raised eyebrow. He was also looking at the sky, his hair still stuck to him from all the sweat and water,"I know I do not have the right.... stuff."

She laughed loudly. He just gave her the best sex of her life and he was apologizing because he didn't have a knot to keep his cum in. She felt insane the way she laughed as it was just so ridiculous.

"Stop apologizing. You definitely have the right stuff," she said, a smile on her face. Her cheeks inflated a little as she tried to keep her laughter which eased him back into a smile as well.

He let out a sigh, head falling back."My teacher was wrong," he said mostly to himself as they both laid in the grass for a moment,"falling for temptation is actually pretty nice...."

She paused, blinking.

"I do not need strength from temptation," he said, trying again.

She still didn't really get it until she got it."I'm the temptation," She said as though it was obvious.

He laughed and she felt even more stupid. It was right there the whole time. She groaned. Is that really what all the praying was for? How was she supposed to guess all that!? She barely remembered any time he read that Bible book. It was boring and confusing.

"This whole time.....?"

He smiled.

"Before me and the other knights arrived, I did alot of study on dragons and dragonkind," he said very evenly and carefully.

"That's why you speak my language," she sighed, knowing that information.

"Right," he said, clearing his voice,"so I knew when I saw you starting to nest you were entering your cycle soon, however I assumed you had a partner. But then you started to take my things...."

Her skin ran hot with the accusation she knew was true. She hadn't thought about it like that at first. She had always taken things like gold and jewelry, she did not think past that when she kept putting his book in the pile, or taking his shoes at one point. But it turned from small pilfering to the items needed to be near her stuff. She doesn't know when the change happened, but thinking about it, she had done just that. She swallowed.

"And I should have said something, but I started to like that you were doing it. It made me realize I had the temptation to..." he gestured to her and she could feel the warm cum leaking out onto the grass.

This time her entire body ran hot. She knew this time it wasn't just embarrassment. Kat was already starting to get turned on again. The thought of Dallas wanting her just as badly as she wanted him made her head spin. She did her best to keep her hands to herself." And t-that's against your principles?" she wanted to bite her tongue as she couldn't hide the whine behind it."That book you read?"

He paused before giving her a soft smile."May I?"

She swallowed but nodded frantically. She didn't think she could say it without begging.

His hand slid under her loincloth. Her hips jumped as he rubbed her gently, but she was grateful for the sensation. She curled around him, panting, but he continued talking. She struggled to listen.

"Yes," he continued as though he wasn't in the middle of bringing her to another orgasm,"but I did not want to leave you; I was selfish because... I like you."

She let out a small cry as she felt the slip of his fingers into her. Her hips continued trying to hump his hand, but he kept his pace patient."Really," she blurted,"you like me?"

He smiled at her. And she felt herself going crazy. He hadn't answered yet but she still wanted him to put a baby in her, again. Half of those thoughts might have been the heat, but it was only half.

"Really," he confirmed,"more than I probably should..." His fingers curled.

"I-" It was stuck and she couldn't get it out. Her panting was loud as her hips moved against his hand. He rubbed against her clit with his palm in such a nice way each time he let his fingers come out of her.

"Please, right there!" she cried out as she felt it flow. It was quick how easily he worked her through it. She couldn't justify it other than the overwhelming knowledge that he was the one doing it to her. It made her head spin more.

"Go ahead," he said softly in her ear,"I'm right here."

Her hips twitched against his fingers as he worked her through her orgasm. Her eyes rolled for a moment and she could feel his hand keeping the pace. It felt so good. Everytime it was him who brought her there it sparkled something that satisfied her brain. She could feel him kiss her face as she came down.

It was only when she let out a high whine he slowed down. Her toes curled in overstimulation. She sighed as she was given a moment of coherence. He didn't pull his fingers out right away and she could still feel herself twitching around them.

"Ugh," she said, letting out a huff when they finally left her feeling empty. His fingers were covered in her and his fluids. It was hard to have this conversation,"but you broke your vows." She tried her best to get through this without asking him to pump her with his cock for a second time.

Dallas gave her another amused smile. She couldn't understand why he found this so entertaining."I did. But it was broken some time ago," he said, "However my battle was not that. For as much as I like you, I just did not want the head between my legs to ruin our friendship."

"Head between your legs?" She repeated. Maybe that idiom made sense in English but she had no idea what that meant.

"Ah... uhm," he looked to be struggling to translate,"I did not want my desire to mate with you to make things bad between us... I value our friendship very much."

"Oh," she sniffed, smelling his hair,"but you feed me and take care of me. You talk to me and read with me. You tell stories with me and you hunt with me. Now you have bred me. Only the last of those things was missing from already calling yourself my mate."

She could see his ears turn red. It was true. They had acted very intertwined for a while and as the realization grew he just became redder. It was cute. Like a berry or a tomato.

"My goddess?" She repeated at him, making him sputter. She laughed.

"I-"

"I like you," Kat interrupted him. She didn't think he could be redder but she was wrong. It made her smirk a little and she couldn't explain why. He looked like he was going to explode.

"I-i like you too," he said, finally able to stumble out.

"I know," she said, the smirk growing,"you said that."

He laughed at that. His embarrassment was still there but he had this stupid grin on her face. It made her kiss him; over and over and over again. She bit his chin.

"You won't leave," she said, arms wrapping around him.

"I will never leave you," he said, not resisting but he laughed."You could be carrying my child at this point."

She snorted but she could feel the tingle of arousal again."I think you're going to have to give me a bit more than that for a baby..." she said leaning so he would roll on his back.

She could feel it as she sat up. She was much larger than him and he looked silly squeezed between her thighs, but she could make this work. He didn't look against any of this, his face a huge grin under his dusted cheeks.

"I think I can keep up..."

She smirked."Can you?"

When the sun finally set and Kats body finally slowed, they were able to collect everything and make their way back to the cave, upon which Kat noticed Dallas was completely sunburned.

-🖤 end 🖤-
