After returning to Mondstadt from a rather âeventfulâ night and morning at the Dawn Winery Manor, you find yourself meeting Amber for lunchâŚ
Upon returning to Mondstadt you met with Paimon and Amber for lunch at the Good Hunter, bringing the much promised grape juice from the night before. You all joked and laughed, enjoying the bright sunny weather and traditional cool Mondstadt breeze. When you all were fed and stuffed, Amber leaned back in her chair and glanced toward the Knights of Favonius Headquarters in the distance. âOh, [Y/N]! I forgot to tell you. Captain Kaeya mentioned he needed some extra assistance today at the morning meeting. I figured you might be a good fit!â You downed the rest of your refreshing fruity beverage and placed the glass on the table. âOh, really? Did he mention what he needed help with?â Amber shook her head. âHe wasnât very specific, but probably has something to do with the stables. I know heâs a bit short on hands this week with the main stable hand being sick.â âOh~! [Y/N]! Playing with the horses sounds like fun! Paimon wants to go!â Paimon exclaimed with an excited twirl and clap. Amber laughed. âDonât get too ahead of yourself, Paimon. Horses are a lot of work and require a lot of understanding,â Amber mentioned. Paimon tittered. âHehe~! Paimon still thinks itâll be fun and a great learning experience for [Y/N].â âThat I can agree with,â laughed Amber. âVery well, letâs head out and meet Kaeya then,â you giggled. âYay~!â Clapped Paimon.
**********
You knocked on the wooden door to the Cavalry Captainâs office back in the Favonius Headquarters. âCome in,â came a distinctive voice. You turned the handle and entered the large office, meeting Kaeyaâs starry eye across the room. Another knight stood near his desk, a stack of papers in hand. âAh, [Y/N] and Paimon. I didnât expect to see you two today. I heard you had gone scouting with Amber.â You shook your head. âWe actually just returned from lunch with her. She mentioned that you needed assistance with the stables. We came to assist.â âMmmmmmâŚâ Kaeya let his gaze wash over you. There was something odd about it. Something off about his demeanor. He didnât wear his normal smug smile and the teasing light was nowhere to be found in his good eye. âPaimon is ready to get started! Just tell Paimon where to go!â
Kaeya rose from his desk and turned his gaze slowly toward the other knight. âLizzie, would you be so kind as to take Paimon to the stables and start showing her around. You can even get started on work with her.â âYes, sir!â She responded with the knightâs traditional salute. âWhat about [Y/N]?â Paimon asked. âAh. Yes. I have some⌠Private matters I need to discuss with her first,â he said, his tone quite off. You glanced at him, an unease building within you. He didnât meet your gaze. âOkayyyyyy~! Iâll see you later then [Y/N]!â Paimon bided happily, giving a cheerful wave.
When the door shut, the tension only mounted. Kaeya walked around his desk to you. He met your eyes and grabbed you under your chin, forcing you to look up at him. âSo. Tell me my darling Star-fall. How did you enjoy my brother last night?â Your eyes widened in complete shock, jaw dropping. âB-B-Brother!?â You exclaimed. You tried to retreat, but backed up into the Captainâs desk. âOh? You didnât know?â Kaeya smirked, approaching you again, pressing his body against yours. âDear Master Diluc and I grew up together after his father adopted me when I was just a young boy.â Kaeya grabbed you under the chin again and put his thumb against your bottom lip. You searched his eye, but it was cold. âH-How did you even know about last night!?â You demanded, brushing his hand away. âJust because I donât live at the manor doesnât mean it isnât my home or family. I went there this morning to have breakfast with Adelinde.â âThe maid?â You asked. âYes, sheâs been there for years and is like an older sister to me. Little did I know that you had spent the night and were fucking my brother just above where I was trying to enjoy some breakfast. Loudly, I might add. Made for a rather⌠unforgettable experience.â
Kaeyaâs eyes were hardened. He grabbed you and turned you around. He wrapped his arms around your stomach and pulled you close. You tensed up wondering what he was going to do. You werenât scared of him in any sense, but you could see the anger in his eye. You then felt his shoulders slump. He buried his face against your neck, his breath cool on your skin. âDonât you know I stopped fucking other women because of you? Donât you know I stopped fucking Rosaria because of you?â He whispered against your skin. Your eyes widened and you gripped his muscular arms. âDonât you know I havenât even looked at another woman since our first night together? Donât you realize how I feel about you?â He asked quietly. His voice was far from angry. It was⌠sad.
âKaeya,â you breathed. He gripped you tighter. âYou canât just say my name like that after screaming Dilucâs a few hours ago,â he snarled. Kaeya released you and pushed you down on his desk. The cold wood caught you by surprise as it hit your half-bared skin. You gasped. Kaeya tugged at your shorts and tore them off, bringing them to your knees. âKaeya! W-What are you doing!?â He responded by grabbing the plush of your ass and squeezing it between his cold hands. He kneeled down and spat directly onto your heat. âKaeya!â You tried to get up, but he held you down. You could hear him spit on his own cock as he pumped it. He leaned over on your rather bare back. âDonât you know youâre mine?â He whispered. With the last word, he pushed himself into your body. You cried out as your walls were quickly forced to adjust to him. He grabbed your ponytail and pulled back on it, arching your back. âKaeya!â You cried. He nipped at your ear. The Cavalry Captain pounded himself into you relentlessly. You had expected pain, but he knew better than that. In addition you had expected to be sore from so much with Diluc, but instead you cried out in unexpected pleasure instead.
Kaeya stood up straight and gripped the thick of your hips, still pounding himself into you. You lay across his formerly well-organized desk. You put your forehead against the cool wood, rocking back and forth with Kaeyaâs movements savoring the feeling of his cock dragging along your plush walls. A sharp sensation to your backside brought you back to reality, your head whipping back. He smacked your ass again. âKaeya~âŚâ You moaned to him as the mixed pain and pleasure rippled through you.
The Captain pulled himself out of you and then grabbed you once again. He flipped you over and pushed you further up on the desk. Books, papers, quills, and even an inkwell crashed to the ground on the opposite side. He didnât pay it any mind. Instead, he snatched your legs and hoisted them over his shoulders, pushing himself back into you at the same time. You moaned as he stuffed you full once more. âLock your ankles,â he ordered. You did exactly as he told you to and locked them tightly behind his head, pulling at his neatly braided bun. He then seized both your wrists and locked them over your head.
Kaeya then did the unexpected. He changed tactics and started to roll his hips into you at a steady pace. With every thrust, he hit your sweet spot and stimulated your clit. His hanging balls smacked against your exposed asshole, brushing it ever so slightly. Your brow wrinkled and you mewled in absolute delight at the new sensation. After so much practice with this man, he knew how to hit you exactly right every time. He delighted in your whimpers, watching you with an open mouth, giving you small moans in return. He leaned down, his blue bangs brushing your forehead. He gazed into your [E/C] eyes as he continued to roll his hips. âDonât you know Iâve fallen in love with you?â He whispered, his tone soft and vulnerable. Surprise crossed your face. You knew he had some sort of feelings for you, as youâd both expressed that to one another on multiple occasions while having sex, or just casually flirting, but you hadnât realized they ran that deeply. âKaeya, Iââ He cut you off, pressing his lips to yours. He kissed you over and over, almost desperately as if he wasnât ready to hear your answer.
The Cavalry Captainâs grip on you became lax and you were able to wriggle your wrists from his iron grip. You quickly unlocked your ankles and slid your legs down his arms. Kaeya pulled back from your lips and let you readjust so your legs hooked around his hips instead. You could feel his cock twitching inside of you. You pushed yourself up on elbows. Kaeya hurriedly leaned back over you and locked lips with you once more, caging you in with his muscular arms. His cock began to piston in and out of you once more, dragging across your spongy interior. You threw your arms around his neck and pulled him close, opening your mouth to let his greedy tongue enter. Kaeya breathed his icy breath into your mouth, the cool sensation tingling. He pushed himself back to standing, your arms still locked around his neck. He placed his cold hands on your bare back. You yelped, pulling back from his lips. âWhatâs wrong? Canât handle the cold?â He smirked. He caressed the smooth muscles along your back. His fingertips felt as though frost was forming across them.
He rocked his hips into you with a quick and short pace, our close proximity stimulating your clit, the heat within you quickly rising. He let his icy hands wander up and down your half-clothed body, touching every piece of bare skin he could reach. You leaned your head back for him. He smirked with his traditional crooked smile and he dipped his head so that his lips could meet your neck. He blew frost on your sensitive skin. The sensation, in addition to the pulsing off his cock in your heat, was intensely arousing. You moaned, arching your back into him. Kaeya brought his hands around to your front and pulled your corset down. Your breasts bounced out to greet him, your nipples hard as ice. He grinned at you before placing his cold thumbs over them. âKaeya!~â You moaned loudly, your walls clenching around him. He groaned loudly. âDo that again Star-fall and Iâll cum.â
You snickered and kissed him, intertwining your tongue with his. Kaeya drew circles around your breasts. Just as your nipples began to defrost, he pressed his ice cold thumbs to them again. You jumped at the sensation, walls tightening sharply around his cock. Kaeyaâs body buckled and shook as he released hot ropes of cum into your body. He gasped, grasping the desk for support and he rode out his unexpected high. You held onto him tightly, creating tiny movements with your hips to force friction to your clit. You were almost there. It was just out of reach. Just as Kaeya began to calm down, your walls clamped down around him once more as you hit your own high. He fell to his elbows on the desk. â[Y/N]!~â he groaned loudly. Pleasure ripped through your body as all your muscles flexed. âKaeyaâŚâ You moaned, your grip on him loosening. As your body calmed, you let your legs drop from his hips and your hands slide to his arms. Kaeya, shakily, managed to stand back up and slipped his cock from your oozing core.
You grabbed him by the chin. His starry eye met yours with surprise. âTell me exactly how you feel and what you want from me,â you told him flatly. His eye softened and he cupped your face gently. âI want this. All of this. With you. All the time. I want you. As my girlfriend. Maybe as my wife one day. I donât know what sort of sorcery you brought with you when you fell out of the sky into Teyvat, but whatever it is⌠I think Iâm in love with you, [Y/N],â he said. Your heart fluttered. You bit your lip and smiled. You pulled him closer, your heart beating harder, butterflies in your stomach. âI think Iâm falling in love with you too, Kaeya Alberich.â You drew him in for a kiss. There was no burning passion, no intense desire. It was pure and gentle.
