The Doctor's Sacrament by seidrade
Chapter 3: Temperance
Summary:
"Perfect," Ratio said, and somehow that very word alone served to suffuse her entire being with warmth and longing. "Place your hands on me, somewhere comfortable."
After a moment's hesitation, Sunday reached out to rest her palms on his knees, feeling that to be a safe spot. She glanced up at him again for confirmation that she hadn't somehow misunderstood his directions. "Like this?"
"Mm. Very good. Now, tell me, Miss Sunday. What is the extent of your experience performing oral sex?"

A brief reprieve from her exam finds Sunday on her knees for the doctor. It feels strangely natural.

A digital sketch of Dr. Ratio stripped naked and leaning backward against an implied surface.
His chin is tucked towards his chest and his visible arm is held behind his back, as if pinned or bound there. His posture is tense and heโs looking down at his own body, frowning slightly with a mix of chagrin and disgruntled arousal as if wondering, perhaps, why he allowed himself to be talked into such an undignified scenario.
The drawing trails off at his hips, with a long line implying the upper curve of his half-hard cock. The background abstract swirls might be reminiscent of cocktail ingredients being mixed, or maybe they just represent cum, depends on how horny you are. (Por que no los dos?)
POV: you made Dr. Ratio a drink to encourage him to demonstrate some of the modeling techniques mentioned in his highly lauded, recently published treatise on figure sculpting

The Doctor's Sacrament by seidrade
Summary:
"Miss Sunday. Look at me."
Feeling like a schoolgirl about to be lectured, Sunday dragged her eyes up from the relatively safe vicinity of Ratio's arms and chest (oh, who was she kidding, there was nothing safe about that) to meet his rose-hued eyes with trepidation. Ratio gazed at her with an odd sort of intense yet benign interest, not unlike his usual scholarly mien, but she could feel the energy rolling off him. He was clearly enjoying this.
"I'll make it easy for you," Ratio began again, that familiar patronizing tone curling into his voice. "Lift your skirt so I may examine you."
Sunday limps back onto the Astral Express late one night after an unexpected rendezvous with the Stellaron Hunters leaves her bruised, tattered, and exceptionally well-fucked.
Unfortunately, one Dr. Veritas Ratio has been visiting the Express and is still awake to intercept her attempt to sneak through the party car. A misunderstanding leads to Sunday allowing the doctor to examine her injuries, only for it to become obvious to both of them that, for all her shame, Sunday still inexplicably aches to be touched.
Naturally, Ratio has a solution.

I can also see Caelus try to make Sunday be a dom while still bottoming aka Caelus tying himself up and letting Sunday use him as a dildo or put his hole on Caelus' face and Sunday cant excatly do it he is a sub and i want Dan Heng to catch them in that pose and Sunday to die inside

Realizing he was being actually evil and manipulative and leave right away disgusted with himself. Only he doesnt know it wouldve been significantly better if he gave Sunday an aftercare thus Sunday fall harder
I want Dan Heng to realize the tension between them where Caelus tries to sweep it under

I want Sunday to get fucked by Caelus who wasnt that much keen on letting Sunday into the express. Its like him realizing how submessive Sunday is and gets annoyed by it and tries to break him to show his "real face" and pushes too far and gives Sunday a sub break and Caelus feels horrible-

Like imagine his younger greedy selfish self is abusing Sundays love to dub con him and Sunday letting it cause he loves Aventurine so much no matter what shape or form and would want to help him no matter even at the cost of being dubconned :3c

Idk actaul age of Kakavasha at that timeline but i want Sunday to be topped by a demanding sadistic dom who is shorter and younger than him after his current lover, aven, doms him definetly more calmer than this and Aventurine to find this out
03.08.2025 22:54 โ ๐ 1 ๐ 0 ๐ฌ 1 ๐ 0
And not an adult and highly traumatized one at that so he cant say no to his wishes cause he wants to help but it feels all wrong so very dubconnish
Aventurine should find his younger self inside his Sunday when he comes home too LOL
03.08.2025 22:50 โ ๐ 1 ๐ 0 ๐ฌ 1 ๐ 0
So he is going to take all his frustrations out of this very submessive man who is oh-so accommodating to him
I also want Kakavasha to finally dom top someone after being used as a sex slave and just enjoy the high of it
While Sunday thinks he is kinds cheating but also not but also this is a kid
03.08.2025 22:50 โ ๐ 1 ๐ 0 ๐ฌ 1 ๐ 0
And fuck his future boyfriend. I want to imagine post killing his master Kakavasha is more full of hatred to the world and his circumstances and i think he would be even more hateful to his future self for getting to live in all this luxury while he has to wait by being send to his own timeline
03.08.2025 22:50 โ ๐ 1 ๐ 0 ๐ฌ 1 ๐ 0
And i want Kakavasha to learn his future self landed himself this angel looking submessive boytoy at least according to the winged man named Sunday they are dating so same thing
And while his future self, Aventurine, is away he decides he doesnt want to miss out the fun

It's unclear to Veritas how they ended up here.
No, that's inaccurate. What he ought to say is, it's unclear why he has agreed to partake in this absurdity.
It started with Aventurine, as it ever does, insisting Veritas ought to come out for drinks with him and Sunday. This was nothing atypical for a weekend eveningโ Sunday didn't drink, but Aventurine had found a lounge that was quiet enough for Veritas' tastes and featured a substantial mocktail menu served up by a ruggedly handsome bartender that Sunday had thus far done a miserable job of pretending he didn't want to sleep with.
Veritas often found himself accompanying the two of them, even if he was not in the mood for alcohol himself. It wasn't terribly difficult to turn down Aventurine in favor of a quiet evening at home with a bath and his books, but the problem lately was that he hadn't wanted to.
Their so-called situationshipโ as Topaz had so unflatteringly insisted was the proper title for the nature of their arrangementโ had recently expanded to include Sunday, thanks to Aventurine's incessant flirting and cajoling.
Veritas could admit, there was something satisfying about seeing someone else on the receiving end of Aventurine's conniving tactics for a change.
And Sunday did fluster so prettily, despite his surprising capacity for taking cock. Veritas had entertained more than one illicit fantasy of bending him over in the back room of the lounge and enlisting that scruffy, unkempt bartender to help stuff him full while Aventurine looked on with a heated grin, recording on his phone.
A weeping, sobbing Sunday was so far proving to be Veritas' favorite iteration of the man in bedโ and, if he was being terribly honest, any iteration of Aventurine would easily count as such, but it was assuredly better to keep those thoughts to himself.
I do have the tiniest scrap of implied Galladay (from Ratioโs POV) to shareโฆ I donโt know if this is going anywhere but itโs the start of an AU wherein Sunratiorine are a thing and Aventurine is trying to goad Ratio and Anaxa into hatefucking, so Sunday might be involved, if I ever finish it ๐
