Summary
“Didn’t I say take off your clothes?” Sunday whispered back, his fingers brushing Gallagher’s thigh and sliding up. “That means your pants, too.” He hooked his forefinger at the waistband of the sweatpants, tugging on it.
Gallagher chuckled. As he brought his fingers up to the sweatpants’ laces and undid them, Sunday shamelessly spread his legs—the palm of his hands pressing on the mattress behind him.
Oh, how interesting that night was going to be.
Gallagher is Sunday’s most beloved muse. He’s part of every sketch, painting, and drawing the artist does. It’s an honour to be worshipped by someone so talented.
And it’s so satisfying seeing himself painted in Sunday’s ‘Prohibited Drawings’ sketchbook.OR
Gallagher vigorously complies with Sunday’s sexual fixations.

Summary
“Show me.” He demanded.
Sunday swallowed thickly, throat bobbing.
“Show… Show you…?”

Right now, all Sunday could think about was the person before him.

Guilty Pleasure by Grimour (OmniaImmortalis)

Summary
“Come on in, darling.”
The door opened slowly, and Aventurine's expectant smile grew, legs spread on the sofa, donning one of his dark green suits.
Sunday's foot made it past the threshold, wrapped up in white stocking, reaching all the way up to his creamy thigh, and Aventurine's stare followed it indulgently, reaching the frilly set of pink lingerie. There was a heart cut-out by his pelvis, filled in by grey, fluffy feathers. Cute.
“Don't be shy, let daddy see you in full.”
For a moment, Sunday bristled, tinted lips pressed together, brows furled – though his cheeks grew red. He obliged, not without muttering: “This is ridiculous.”
Aventurine laughed. "And yet, you're hard.”

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.

Summary
“You want me to punish you? As in, during sex?”
Sunday’s jaw snaps shut. He averts his eyes, heart galloping wildly in his chest. After an age, he finally nods, short and stiff.
“…Won’t you at least look at me when I give you my answer?”alternatively: an avenday relationship study wrapped in filth

Summary
To Aventurine, life itself is a grand gamble, and people are merely chips in his eyes. Haunted by strange hallucinations that have plagued him his entire life, he's set on surviving in a world of corporate power. Then, a wild card is thrown into his hands: Sunday, an angel, cast down to earth on a mission born of desperation...
Thrown into the heart of chaos, Aventurine and Sunday must decide what they are to one another: enemies, allies, or the reason to burn the world to the ground. Perhaps their meeting was written in the stars, but will it ignite a path to salvation, or consume them both and lead to their ultimate downfall?

Summary
Sunday walked toward the tied up man with his hands folded behind his back and his spine straight, a small smile on his lips. His sleek black shoes clicked on the wooden floor, came to a stop right between his own.
"How are you, my child?"
Aventurine laughed a little, dragging his gaze over his black-white get up, high collar hiding the hickeys from last night.
His hands were bound behind his back, broad silky red binds weaving around his wrists, the same material tying his ankles and calves to the chair. The first few buttons of his shirt were undone, revealing part of his chest.
“Horny as hell, Father, if you wish to help me out with that.”

Summary
From his nape, to his waist, down to his thighs, and his oh so sensitive wings; his muse may praise the order but aeons does he want to eternalize the harmony of the sounds he sings.
With a hankerchief in hand, Sunday had absolutely no idea how it had descended to this. But with the intoxicating feeling of sin, he can't help but be pulled in.
