Chapter 1: Day 1: Masturbation [Aether/Kaeya]

Chapter Text

“So he’s in Nod Kari now? My,my, he sure moves fast.” Kaeya chuckled as he looks at the letter from Aether that Mika delivered since they had run into each other.

“Yeah! He was going to mail this but I offered to deliver it since I knew had to stop by in Mondstadt for a bit for the Grand Master.” Mika smiled before bidding a farewell and promptly leaving the room, probably to give the captain privacy to read the letter. As much as he wanted to tear open this letter and read it, he had a feeling he should wait till he gets home.

——

Kaeya walks into his home and closes the door behind him.

“Better get comfortable.” He says to no one as he looks down at the envelope in his hand. Or perhaps he was imagining Aether standing in front of him, hands on his hips as he always did when they were together.

He walks to his bedroom, sets the letter down on the bed and starts to change his clothes. If he was correct, which he’s almost positive he was, he won’t need much. So he just slips on a simple white shirt and walks back over to the bed. He takes the letter and gets himself comfortable before finally opening the envelope and taking out the letter.

Hello Kaeya, how are you? Good I hope. I’m in Nod Kari and as I’m sure you guessed, trouble has found me.

Kaeya chuckled softly. Aether has a knack for having trouble finding him no matter where he goes.

As much as I want to tell you everything, I’ll save it for next time I’m in Mondstadt. I miss you so much, your voice, your smile, your touch.

Kaeya’s breath hitched as he keeps reading the letter. He was right of course. He reads on, he could almost feel Aether’s touch and his voice in his ear. Describing in writing what the honorary knight wanted to do to him but couldn’t. Aether may not look it but he’s incredibly possessive of the cavalry captain, the amount of times Kaeya has been pulled away from a gathering simply because Aether didn’t like how ‘friendly’ other knights were being even though they weren’t drunk and took him in the upstairs of the Angel’s share.

“Damn it….” Kaeya whispered under his breath, feeling heat blossom across his body. He slowly runs a hand down his torso before reaching between his legs, gasping softly as he feels his fingers run over his wet folds. Gods how he wishes Aether was here.

He sets the letter down on the nightstand as he pushes two fingers in his now soaked pussy, craving for Aether’s touch as he pumps his fingers in and out, his other hand pushing up his shirt and pinching one of his nipples.

It’s been so long since he had last seen Aether, missing his voice and smile. His pressed a third finger inside, back arching as he imagined all the things Aether would do to him once he returned to Mondstadt.

“Aether…” Kaeya mewls, pinching and pulling his nipples as he tried pushing his fingers in deeper. Already feeling so close to the edge. He thought about that time in the Angel’s share when Aether bent Kaeya over a table and took him there, not caring if anyone heard or found them.

“Fuck-Aether!” Kaeya gasps sharply as he cums, juices spraying out of his pussy and making a mess on his thighs and bed. He goes limp, panting hard as he relaxes from his climax.

“Hm….perhaps I’ll write him back and tell him about his little session to mine.” Kaeya snickered to himself.

Chapter 2: Day 2: Kidnapping [Yelan/Fatui Skirmisher Geo]

Chapter Text

Would you call it an obsession? Maybe most would but she’d rather call it-interest. Interest in seeing more. That’s all it was. That’s why she finds herself tailing the same Fatuus for weeks on end. The same one she grabbed awhile back. She’s been finding her mind wandering back to the night, the way he squirmed as she made him talk.

“Oh Yelan you need a hobby.” She dryly laughed from where she hid. She wasn’t ashamed but she knew the time she was spending tailing this guy around could be used for breaks or a nap in between her jobs. Just when she was talking sense into herself-the Fatuus walked in a different direction away from his comrades.

The nap can wait.

Just like before, she was quick to get behind and knock him out. Exciting.

——

“Ugh….where-? Huh?!” The Fatuus wakes up but have sensed the obvious déjà vu and tugged at his tied wrists and looks up, seeing Yelan as her desk again but was leaning back on it-a very strange look on her face.

“Hello, my dear Gem.” She smiled and loved the look of utter confusion showing from his single glowing eye.

“What?! You again?! I wasn’t even doing anything!” He says, wracking his brain as to why he found himself tied up on a chair in front of this lady again. He grows more nervous as Yelan wordlessly walked up to him before feeling a single finger run up his neck and titled his head up to look at her.

“Relax, I’m not here to hurt or get intel on you.” She says, running her thumb over his covered mouth. “I just had to see you again.”

“…..huh?” He wasn’t sure how to respond to that. She had this dark glint in her eyes, almost bordering predatory. He wasn’t sure if he should be scared right now or not. He jumps a little, feeling a hand cup the side of his face, petting it with her thumb. “I-huh?”

“I’ve had many tied to this chair before but you-you’re just so.” She said, leaning in to speak into his ear. “Cute.

“Ever since that night I couldn’t get you out of my mind.” She continued, stepping away and walking around the chair, eyes never leaving the Fatuus. She thought she’d be satisfied with just this but she wanted to see more. No no, she shouldn’t indulge.

At least not today.

She snaps her fingers and the hydro ropes disappear and free him. He felt a kiss to his cheek and a soft whisper.

“I’ll see you again, my dear Gem.”

And like the wind she was gone. The Fatuus sitting there still.

“What the hell just happened? ….and why did I like it??????”

Chapter 3: Day 3: Threesome [Caelus/Phainon/Dan Heng]

Chapter Text

“Hey Phainon, would you be open to a threesome?” Caelus asked out of the blue while he and Phainon were walking around the marketplace.

“Well that’s quite the conversation starter. What makes you ask?” He asked in return.

“I think Dan Heng has a crush on you but won’t say anything since you and I are dating but I’d totally be down to share. You?” Caelus looked up at the man, waiting on answer.

“And this is why I adore you.” Phainon cooed and kissed the man on the cheek. “Of course. I’d be lying if I said I didn’t have a crush on Dan Heng myself.”

“Then this’ll be easy!” Caelus cheered and Phainon laughed at his enthusiasm.

——

Honestly it wasn’t as hard to convince Dan Heng into the idea as they thought it would be. Further proving what Caelus thought. The dragon was definitely into Phainon but would never get into them, but definitely jumped at the idea of sharing.

They currently have Phainon sandwiched between them, Dan Heng yanking away his clothes while Caelus was kissing him deeply.

“Ha~ eager huh Dan Heng?” Phainon chuckled softly before his breath hitched as he feel Dan Heng lick a line over his trembling folds. When did get his pants off? When did he move down between his legs??? Phainon holds onto Caelus as Dan Heng pushed his tongue deeper into his pussy, Caelus’s hands finding their way to his chest and squeezing them, pinching his nipples.

“Mmm!~ Enough of the foreplay, I can take you both.” He says with a smile. The two guys must’ve been just as ready. They were quick to take their own clothes off and line their hard cocks up with his soaked pussy.

They slowly slide inside him, Phainon silently gasping as he feels them fill him up. They bottom out rather quickly and give him a moment to adjust before he’s giving them the okay to move. Phainon wraps his arms around Dan Heng’s shoulders as the two thrust in and out of his pussy.

“Don’t think-I’ll last long!~” Phainon moans, alerted feeling so close to cumming. Having two large girths inside him feeling almost too good. That just encouraged the two to fuck into him faster and harder, wanting to make the man cum on their cocks.

It works well as Phainon claws at Den Heng’s shoulders, cumming with a loud shout, juices spraying out of his pussy. Caelus and Dan Heng fuck him faster before cumming soon after him, their seed gushing into his wet pussy and filling him up.

“Feel good?” Caelus asked, smirking.

“Mhm….again?” Phainon asked, batting his eyes at the two.

Chapter 4: Day 4: Voyeurism [Lighter/Billy]

Chapter Text

“You sure you’re gonna like this?” Billy asked, sitting on the bed in nothing but his underwear. Lighter was across from him in a chair only in his pants.

“Absolutely. You’re gonna look so good.” Lighter says with a smirk and Billy fidgets, feeling his pussy already dripping wet. He looks down at the dildo beside him and nods to himself. He climbs up all the way onto the bed, making sure Lighter could see him clearly, slipping his underwear off and sitting on his knees, positioning the dildo under his pussy.

He slowly sinks himself down, moaning lowly. He could feel Lighter’s eyes on him and that excited him even more. Soon he’s bouncing up and down on the toy as Lighter watched from where he sat.

God Billy looked so good. He unzips his pants and pulled his cock out, beginning to slowly stroke it as he watched the robot fuck himself on the toy. He so badly wanted to push Billy down on the bed and fuck the robot himself but he wanted to wait.

“Liiiiiighter.” Billy was already whining and the champion laughs softly, stroking his cock faster.

“You’re doing so good, baby. You can cum like that. Fucking yourself with me watching.” Lighter comments. “Putting on such a sexy show.”

He grins as he hears Billy whine again, hearing the bed creak as the robot moved faster on the toy. God Billy looked so good like this…he felt his cock twitch as he strokes himself.

“Lighter! Liiiighter!!!” Billy moans louder and louder, going harder and pressing the dildo deeper.

“Go on and cum for me, baby.” Lighter groans, stroking his cock faster, eyes never leaving Billy. They reach their climax together, shouting each other’s name. Lighter gets up and pushed Billy down onto his back, pulling the toy out. “My turn~” he says as he feels Billy wraps his arms around his back.

Chapter 5: Day 5: Finger Sucking [Fem!Rover/Brant]

Chapter Text

She wasn’t even sure what they were doing. Was it a celebration? Just a normal party? Or just honestly a reason to drink? Any are a possibility.

Her she sat, an arm around her shoulders as Brant drunkenly rambles about a job well done and so on and so forth. Everyone was having a grand time.

“Come on, Rover have a drink! Relax!” Brant giggled, swaying a little on his feet.

“Somebody needs to stay sober to make sure you stay out of trouble.” Rover says, giving him a knowing smile.

“Aaaaah come on give me a little credit.” He pouts, feeling a hand on his hip comer he let her go. Okay sure he probably would’ve fallen if she hadn’t done that but he’s perfectly fine!

“How about instead of running your mouth, you drink some water.” She says, making him sit down beside her at the table tbh were at.

“I’m fiiiiine.” He continues to insist. She gives him a look and sets a glass of water down, dipping her fingers in and shoving them in his mouth before he could take another swing of his drink.

She becomes surprised when he sucks on her wet fingers, swirling his tongue around each digit and god this was so lewd. She gulps as she watched him and eventually pulled them out when he was done.

“Happy? I had water.” He says with a smirk. Damn it he knew what he was doing. She dips her fingers in the water again and holds them up to his lips.

“Keep at it then. You have a full glass to drink.” She says and he took the challenge, seeing the obvious prize at the end.

Chapter 6: Day 6: Outdoor Sex [Jing Yuan/Welt]

Chapter Text

Another day on the Luofu. People walking, coming and going. Just enjoying life.

However unbeknownst to any of them, tucked away in a corner of a garden behind a tree, their General was having a private moment with Astral Express senior, Welt Yang. Not to trade intel or casual conversations. No.

“Jing Yuan, we’re going to get caught.” Welt whispered as he gets hoisted up by his thighs and pressed against the tree, gasping as he feels the man’s large cock press lightly on his wet pussy.

“Nonsense. No one ever comes here.” Jing Yuan says, pushing inside Welt and wasting no time in moving. Thrusting in and out as Welt wraps his legs around the General’s waist, moaning loudly without shame, forgetting they’re outside. Anyone could walk over and see them.

“Too impatient to wait to find free time. Needed you.” Jing Yuan says huskily into Welt’s ear, fucking him harder, holding his thighs tightly.

“Willing to be late just to have some time with me?” Welt teased, drool running down the corner of his lips, arms wrapping around the man’s shoulders.

“Of course.” Jing Yuan says without hesitation before kissing him, tongue wasting no time in invading his mouth.

“Mmm gonna cum, Jing Yuan!~” Welt gasps sharply, pulling away from the kiss and shouting as the general sped up, the sound of skin slapping on skin growing lewder by the second.

“Jing Yuan- mmmm cumming!” Welt shouts, juices gushing out of his stuffed folds, followed by Jing Yuan slamming his cock all the way inside and cumming. His seed filling him to the brim.

“I think we have time for one more yeah?” Jing Yuan pants. Welt just hits his shoulder lightly but he didn’t object to the idea. Looks like they’ll be busy.
