Fitsius, smut, bratty bottom!Fitz

Sneak Peek:

“Is there a problem?”

He turned at the sound of his host's voice, breathing in through his nose before trying to come up with a response. He couldn't exactly tell the truth - that he was from the past, here to save his team and take them home or get far away from the destroyed earth, that his two closest friends were so close but so far away because he was there but not with them - that would completely destroy all of his chances of actually doing the things he had come there to do. So, he put on a frown, and channeled the frustration he felt with the entire situation into his tone. "I asked your servant a question, which she ignored."

"My apologies." The response he got from Kasius was calm, the words even and controlled. Rehearsed, almost, practiced, perfected - and maybe he knew a little bit about that, keeping up appearances, especially in front of people perceived to be lesser. "My servitors are only allowed to hear the voice of their master."

At the word, the title he had given himself, Fitz felt something twist in his gut, and quickly tried to push the feeling away. There was a flash of an image, of strong arms and firm words and more touch that he'd experienced in decades. The jacket on his shoulders and the layers under it only did so much to hold in body heat when his body barely created it anymore - seventy years on ice had made that difficult, sucked all the warmth from his cells and left nothing behind. He wasn't always cold, per say, but he wasn't as warm as he used to be, and likely wouldn't be again. And it would be far easier to leech heat from someone else than to wait for it to build up himself. But it would be extremely inappropriate to seek out that kind of comfort from the very alien he was trying to rescue his friends from - and he didn't want to, no matter what images his brain came up with.

Doctor!Kasius + Anxious Dad!Leo

When Ambrose Kasius was growing up, his only real option was to go into the family business, follow his father into the military and make a career out of climbing ranks and being a hero. He decided to go to college, first, explore his options - it was just supposed to be a gap year, a break before he did what was expected of him. Two years later, he had settled on a pre-med major, and his little brother was going into the military, instead, filling the hole that he’d left in their father’s big plans.

After getting his degree and finding a job in the city that paid well, as a fully established pediatrician, he thought that would be the end of things. He thought his family would be proud of what he had accomplished, that he was saving children and doing something more with his life than following and giving orders. When it turned out he was wrong, he cut them out of his life, continuing to pursue the career he’d picked for himself.

Leopold Fitz thought he had it all - PhD before 16, a wife who he loved, a daughter who worshipped the ground he walked on - and then his 30th birthday came around and everything went to pieces. Getting laid off from his lab job due to budget cuts was never part of the plan, and neither was the divorce, and having to ask for his father’s help to pay for a small apartment was just too embarrassing to think about. When the custody agreement was easy to arrange, he thought everything was finally going to settle into place while he got his feet under him again.

The very first night she was spending at his new place, Alya complained of a stomach ache just after bedtime, and Leo was too anxious about all of the possibilities to do anything but rush her to the emergency room.

Fitsius, doctor!Kas, fade-to-black smut

Sneak Peek:

Leo set down the last box in the middle of the living room, taking a moment to stare at his boyfriend’s things. The cardboard looked out of place in the small space, covering the seats of his couch, taking up some of the kitchen counter, blocking the bedroom door. He was so used to being alone, to having a space that was only his, and now he was letting someone in.

The bed would be warm every morning, and the shower would have an extra bottle of shampoo on the shelf, and there would be twice as many mugs in the sink. It would be domestic, and safe, and all the other things he never let himself hope for.

When he felt hands on his shoulders, he didn’t hesitate before leaning back into the waiting chest. Ambrose was warm, as always, and his arms were strong enough to hold Leo upright with ease when they wrapped around his torso. Moving in together had never necessarily been the plan, but it was their reality, and it was nice.

Fitsius, a moodboard

definitely inspired by a conversation with the light of my life @kaytikazoo and yes i gave them a ship name what’s your point?

Fitsius + Business Rivals to Lovers AU (an expansion on my Only One Bed post)

Alistair Fitz and Taryan Kasius have been rivals for as long as anyone can remember, and if they happened to drag their sons into it, that’s no one’s business but their own. For the most part, the boys have no problem avoiding each other and being cold in line for coffee in the mornings and playing up the competition for the media.

It’s only when a certain heir to the Fitz family fortune ends up sharing a hotel room with Taryan’s youngest, due to an unfortunate mix up, when that begins to change. 

After that weekend, the rivalry seems stupid, and morning run ins at the coffee shop are warmer, friendly, instead of some show for whoever may be watching. Soon enough, they aren’t Dr. Fitz and Mr. Kasius, anymore, but Leo and Kas, and their fathers absolutely cannot find out.

hello sounds like come here

Summary:

Fitsius + Incubus!Kasius, Doctor!Leo

On the way home after a long night at the Emergency Room, Doctor Leo Fitz comes across a man, bloodied and hurt, slumped against a car, panting and unable to stand. Leo took an oath, and he is going to uphold that oath, even if this man doesn't want to go to the hospital and doesn't want his help. Instead, he takes the man, who calls himself only Kasius, back to his own apartment nearby, and tries to patch him up. No matter what he does, Kasius isn't getting better. He's still pale, and trembly, and shaky.

It's then that Kasius admits that he isn't human, which isn't uncommon, Leo sees non-humans at the Emergency Room often enough. He is an incubus, and he is practically starving. He will not heal until he feeds, and he eats sexual energy. Leo doesn't hesitate to offer himself, giving him what he needs to finish healing.

Kasius, holding this human doctor who willingly offered his life's spirit to him, doesn't want to admit that it was the best sexual energy he's ever consumed, and he wants to keep that in his palate. If he skips a feeding, or lets himself get hurt so he can come crawling back for Leo's help, he doesn't mention that. And if Leo understands exactly what's going on, he doesn't mind because Kasius holds him like he's more than an appetizer and kisses him softly in the morning.

Fitsius + Got Distracted While Trying to Leave for Their Date

"Ambrose," Leo groaned as Kasius' hands slid up under his jacket. "We're supposed to be leaving. Our reservation -"

"Can be moved. Don't make me step away from you after not seeing you for most of the week, Leo."

"Fine. Five minutes."

"Five minutes," Kas agreed.

They didn't end up making their reservation.
