Chapter 1 - Another Meeting With Kaeya

"And that's today's commission done!" Amber says, handing in the reports over to Katheryne at the Adventurer's guild.

"Well done, Amber. From your recent performance, you are just behind the Traveler in terms of efficiency." Katheryne states in her usual robotic tone.

"Of course I am...." Amber mutters to herself, wiping some sweat from her tired brow.

Even after her training with Sir Kaeya, Aether was still proving to be quite the diligent and efficient Outrider.

"Oh! But I guess if that's everything, then I'll be off." Amber smiles after realizing she hasn't said anything in the last few moments.

After waving goodbye to Katheryn, Amber began to make her way toward the Knights of Favonius headquarters.

While some might consider her a workaholic, Amber always wanted to be at the top of her game when it came to everything. And if that meant losing a little bit of free time, she was more than happy to do so if that ultimately meant helping more people in the end.

Walking up the steps to the building, Amber feels the exhaustion in her legs as she moves up them. But nevertheless, she continues to move and extend her hand out to open the door. Only to have the door open by itself as both Jean and Lisa come walking out.

"Oh! Amber." Jean smiles as she sees her fellow knight. Even though she was the acting Grandmaster, she still had a lot of respect for the Outrider.

"Hey, Jean, Lisa! What's up?" Amber says, always more than happy to talk to her close friends.

"We were just about to head to the Angel's Share to have some drinks with Diluc. Would you care to join us?" Lisa offers.

"Oh, no, that's fine. Thank you for offering, however. But I got a go train." Amber explains, looking a little sheepish.

"Are you sure? You've been working a lot lately. And while that's admirable, I don't want you to burn yourself out." Jean voices her worry.

"Thank you for your concern, Jean. But I'm fine. I've just been learning ways that I can improve being a Knight." Amber responds. "It's honestly amazing. For the longest time, I thought I had a grasp on what it meant to be a Knight, but now I'm learning there's so much more to it." Amber goes on to say, at the same time reaching into her pocket to pull out her watch.

"Oh! I gotta before I'm late." Amber says, darting past the two into the building. "I'll be training with Sir Kaeya if you need me!" Amber informs, flashing her familiar, confident smile to the two women behind her as the doors to the building close.

"Hey Lisa," Jean starts, turning toward her close friend, a worried expression on her face. "Is it me, or has Amber been seeming a lot more.... Mature, since she and Captain Kaeya took on more commissions together? You don't think he's doing anything unsavory with her, do you?"

"Who, Kaeya? Oh you worry too much, Jean. We both know those two can barely stand each other as is." Lisa laughs, attempting to alleviate some of the concerns the acting Grandmaster of the Knights of Favonius was quite obviously feeling at that moment.

"Yeah, your right." Jean relents, letting out a sigh before shaking her head and turning away from the door. "C'mon, let's keep going."

"Yes, it would be a shame to keep your boy toy waiting, wouldn't it?" Lisa smiles slyly at Jean.

"L-Lisa! You know it's not like that." Jean admonishes, her face flushing a slight shade of red at the comment.

"I know, I know. I'm only teasing." Lisa laughs as she continues to walk alongside her friend. Although, she did have her ideas.

----

Amber's hands sweat through her gloves as she stood in front of the door to Kaeya's office. Even after everything, she couldn't help but feel timid.

However, with a slight huff from her mouth, she still raises a hand and wraps her knuckle across the wooden door.

"S-Sir Kaeya? A-Are you ready for me?" Amber asks, her voice coming out more nervous than she would've liked.

"Of course, come right in, Outrider." Kaeya's familiar, sly voice gives her the go-ahead to enter, which she does.

Sitting behind his desk, a slight frown adorns the Calvary Captain's face as he finishes signing a few papers.

"Have any troubles with the commission reports?" Kaeya asks, his gaze staying down and focused on his work.

"Not at all. Look, while you might still see me as some sort of rookie, I still know how things work." Amber responds, sounding annoyed.

"Oh, you do, do you?" Kaeya asks, putting his quill down and picking up his papers before walking past Amber and filing them away.

"I must say, even after all the hard work I've done, they still see to fit me with meaningless paperwork." Kaeya sighs. "Perhaps when all is said and done, you could do such work for me? Maybe that would be a proper position for an Outrider such as yourself." Kaeya says playfully.

"Well, as a Knight of Favonius, we are all expected to do our fair share of work. Even if it means doing things we might necessarily want to do. As Calvary Captain, you surely must know this." Amber retorts, grinding her teeth together as she slightly leans over the front of Kaeya's desk.

"That's why I have you, to help remind me of all those little things I forget about." Kaeya says, coming up behind Amber and getting a look at her. "Well, that, along with certain other reasons." Kaeya leans in close and whispers into Amber's ear, causing a shiver to rack up her spine.

There were so many things Amber wanted to say at that moment. But she couldn't help but feel so soft when it came to him. It was almost like he knew the exact words to say to get her into such a state where she was his to do with as he wished. And a part of her kind of liked that.

"Now, then. I suppose we should get started." Kaeya remarks, extending both of his hands out to grab at Amber's hips, causing the Outrider to jump under his grip as he slowly felt her up. Going from her hips to her sides and then all the way up to her toned stomach before eventually stopping at her chest. His strong fingers grabbing hold of the fabric before slowly pulling it away, exposing her average-sized breasts.

By no means was Amber lacking in that regard. She always thought that she had a fair amount there to see. She also knew that she wasn't on the same level as someone like Lisa. Who, due to her interesting choices in clothing, allowed those around her to get quite the eye full. 

"Seems our training has been benefiting you in more ways than one." Kaeya chuckles, causing Amber's face to burn even hotter. His touch was so skilled as it moved across her body; it made her squirm, but she wanted him to keep touching her.

"But fitness isn't the only thing I'm looking for." Kaeya says before his hands shift toward her waist and slowly unzip her shorts. His thumbs then stick under her waistband as he slowly begins to pull them down. Allowing her plump bare ass to pop out from underneath the fabric.

"Nothing. Nice. Just like how I told you." Kaeya smiles while Amber bites her lower lips as she feels his gloved hands reach and pulls her cheeks apart, exposing a small pink beaded toy sticking out from her asshole and leading out to a fluffy white ball. "And you still have it in you, just as what was expected." Kaeya adds.

When the Calvary Captain had given her the toy and told her what to do with it. Amber was at first a little confused, to say the least. In some part of her desperate mind, as she thought about recent events, she could see what they did previously as training in a way. But this was something a little too out there.

Although, like always, his words only seemed to get her to do what he wanted. Even if that meant sticking that thing inside her.... Rear.

"I-I still don't k-know what this has to do with training." Amber stutters out as she stands there nervously.

"It has everything to do with training." Kaeya starts, reaching out and softly tugging on the toy, causing Amber to exhale a short breath of air out through her teeth. "Being a Knight of Favonius requires nearly constant concentration. You have to be able to detect the smallest of things under the most stressful of circumstances. And besides, don't tell me you don't enjoy it." Kaeya says before a stray finger of his brushes up against Amber's slightly wet entrance, causing the Outrider to jump.

Amber doesn't say anything, the most coming out of her mouth being a slight whimper that rumbles out of her throat.

"At a loss for words, Outrider? I wonder, where did all that confidence of yours go?" Kaeya remarks as his finger begins rubbing that spot.

He was loving every single second of this. The once clamoring-to-do-good Knight of Favonius reduced to such a state. It only made her all the more attractive to him, especially as his bulge continued to strain against the inside of his pants.

"Tell me...." Kaeya says, moving in close to whisper into Amber's ear once again. "Do you want it?"

Nervously, the Outrider slowly nods her head to Kaeya's question. Not daring to say anything and risk losing more of her dignity.

"I need you to say it." Kaeya presses, knowing full well how completely unbearable it must've been for Amber at that particular moment.

Steadily, Amber opens her mouth to say something, but nothing leaves her lips.

"Perhaps we can continue this another time when you're feeling a little bit more.... Confident." Kaeya hums before beginning to move away.

It just wasn't fair. How could he treat her like this? She was a Knight of Favonius, not some toy he could play with.

"I want it." Amber suddenly says, the words finally leaving her mouth before she could really think about them.

"Want, what? You'll have to be a little more specific if you want me to give you something." Kaeya presses, still smiling smugly.

"I want your cock. I want you fuck me with your massive cock." Amber finally admits, her heart beating rapidly as every word leaves her lips. A part of her still couldn't believe that she was saying them, but at that point, she was so desperate for it.

"Well, then. I wasn't expecting that much, but I guess I can oblige." Kaeya chuckles as he reaches down to his pants and begins to undo them, going just slow enough that it would get on Amber's nerves. But soon enough, he lowers his pants past his toned rear and pulls his cock out, slapping it down across Amber's rear.

"Wait a minute, what did you want me to do with this again?" Kaeya smirks as he looks back at Amber.

"Kaeya, please." Amber desperately pleaded with the Calvary Captain, unable to take much more of his teasing.

"Alright, Alright, I'll stop with the teasing." Kaeya chuckles before angling his cock right at the entrance to Amber's pussy. He takes his time, wanting to savor every part of what is happening as he slowly pushes his thick-tipped cock past the Outrider's folds. Resting a hand on top of Amber's rear as he slowly pulled her hips against his.

"Ngfh, I must say, you seem particularly excited today." Kaeya remarks with a groan. "Could it be that you were looking forward to this?" Kaeya goes on as he pushes a quarter of his entire length inside her. At the same time, loving how tightly she clung onto him.

"W-What do you t-think?" Amber asks back, finding it increasingly hard to concentrate while her inner walls are spread just by how big he is. Waves of pleasure making their way through her crotch and leading into her brain, where she nearly felt overwhelmed by it all.

"Again, with that attitude, Outrider. A part of me is beginning to wonder if you don't quite appreciate what I do for you." Kaeya smiles, pushing himself in further. Feeling as her pussy twitched and spasmed around his cock as it tried to accommodate his hefty and considerable length.

But eventually, their bodies finally met, which was finally enough to force a moan out past Amber's lips.

"Oh, my. For a second there, Outrider. I was beginning to think that you weren't enjoying yourself." Kaeya chuckles smoothly.

A quick and surefire response aimed back at him was something Amber hoped for, but due to what her body was going through at the moment, the most she could muster was a slight groan mixed with a somewhat annoyed whine.

But soon, more sounds begin to leave Amber's lips as Kaeya starts to pull back. Dragging his long cock back out the way he pushed it in, hitting all those special places once again until only the head remained inside her. Allowing his member to shine with the honey that Amber had coated it within the light of the room before he slowly began to push himself back inside her. This time, moving at a slightly faster pace.

While it might've seemed like he was moving slowly, Kaeya knew precisely what he was doing. This, Amber, knew for certain. A part of her wondered if it was just some sort of way to drag some kind of reaction out of her, with him going at a pace that dragged things out when she wanted it hard and fast. But deep down, she couldn't quite deny the fact that she loved every single second of it.

She didn't know his history with other women, not that she would ever care to ever really ask about something like that. Knowing full well that it would just lead to a cavalcade of more teasing on his part. But from the way that he was using her body, he had to have had some sort of experience if hearts were practically beginning to show up in her eyes.

Moving up into a medium pace, Kaeya's hips moved faster but still had that same precision in hitting all those perfect places inside Amber's body. Her body practically reacted in turn with every single movement he made. Going along exactly the way that he wanted them to go as the Outrider felt the head of his cock touch the entrance to her womb, only seemingly arousing her even further at that point as her body surrendered more and more control over to the Calvary Captain. Allowing him to do practically whatever he wanted while he moved into an even faster pace.

"How are you feeling, Outrider?" Kaeya asks, the smile evident in his voice while he continues to pull himself in and out of her pussy.

"Good...." Is all that Amber says as her pussy clutches down even tighter around Kaeya's thick cock.

At that point, Amber's mind and body had fully given themselves over to  Kaeya. Any rational thoughts she might've had about what she was doing were put to the side as she only served to follow and enjoy the pleasure that his cock was able to grant her at that moment.

It all just felt so good. Kaeya's cock, his thick member, moved through her body with a skill that Amber was absolutely in love with. Controlling her in the best way that she could possibly hope for and be able to feel as Kaeya continued to fuck her at the pace moving.

"Wanna do something real special for me, Outrider?" Kaeya leans and whispers huskily into Amber's ear.

"O-Of course. A-Anything. Just name it." Amber responds, the devotion in her voice being just as obvious as the hearts in her eyes.

"Move yourself for me." Kaeya requests, at the same time slowing down the movement of his hips and cutting off the pleasure for Amber.

"Ok." Amber chirps back as she begins to do just that. Slowly moving her hips back and forth and spearing herself on Kaeya's member.

When it came to most things in life, Amber always wanted to outdo herself. Going above and beyond anything she usually did the next time she did them. And for the most part, she could. Amber was capable of many things, so when it came to something she wasn't exactly experienced in, that being, in this case, sex, it led her mind to do what it always did and pushed her to go further.

Flexing her rear slightly, Amber began to shake her ass across Kaeya's length as she fucked herself across it. The act wasn't the easiest thing to do, but where would she be in life if she didn't go above and beyond what was called of her? 

"Fuuuuck.... Good girl. Just, like, that! Shake that slutty ass." Kaeya groans, obviously enjoying himself, seeing such a plump ass shake and fuck itself across his massive rigid cock. Combined with how tightly Amber's pussy continued to squeeze him, it was all perfect.

"Yes, sir!" Amber responds, encouraged by the response she received from Kaeya to push herself even further. At the same time, she felt her own orgasm begin to build up within herself as she continued to move faster with every passing second. Her mind focused solely on the pleasure coursing throughout her body as she felt herself slipping closer and closer to what she wanted to do.

Eventually, Amber pushes her hips up against Kaeya's one last time. Just enough to push herself over the edge as she feels the tension that had begun to build up within herself quickly fade as her pussy cums on Kaeya's thick rigid cock.

After everything that had happened, Kaeya was more than happy to feel himself begin to cum, also. His enormous member beginning to spray and coat the inside of the Outrider's pussy with his hot white sticky substance that came shooting out of the head of his cock. A satisfying experience, to say the least, for the Calvary Captain.

And it seemed to be a good experience for Amber also as she leaned against Kaeya's desk. Panting exhaustedly and tiredly as Kaeya retracts his member for her pussy before ultimately reaching down to pull his pants back up to cover.

"Another wonderful training session, wouldn't you agree?" Kaeya chuckles, getting a good look at Amber as cum leaked out of her pussy.

"Y-Yes, s-sir Kaeya." Amber pants before she reaches down to pull her shorts back up, leaving behind a dark spot on her crotch. 

"S-Same time, t-tomorrow, I assume?" Amber asks, turning to face the Calvary Captain.

"Correct. Although, make sure to keep wearing that toy." Kaeya reminds her, although he had a feeling she already knew that.

"Great." Amber sighs, finally coming down from the rush of her orgasm as she makes her way to the door and leaves quickly. While she was never that shy to small talk, when it came to Kaeya and how much he irritated her, she'd rather just go.

Once outside his office, Amber takes a moment to brace herself up against the wall before putting the events of what had just happened to the back of her mind. She had to keep up appearances, but at the same time, she would prepare herself for whatever Kaeya might have cooked up for their next training session.

Hope ya'll enjoyed it!~
