Summary
The annual IPC Halloween party is tonight and Aventurine is without a plus one. Well, not after he bumps into a large, hairy, and exceptionally handsome man on the street. Will he come to regret that decision? Or will this full moon be a night he (and his womb) can never forget?

Summary
Fairies cannot lie.
In his life, there are two fairies who have left marks too deep to forget—whether for better or worse, he no longer cares to decide. The first fairy taught him what friendship meant in that cruel, frozen place, and hurt him in equal measure when she shattered everything he lived for with a betrayal colder than mercy.
The second fairy insists she feels nothing for him. Yet she always appears at the most critical moments, saving his life by a hair’s breadth, as if fate itself cannot bear to watch him fall.The third person, not quite a fairy, but the most precious to him, someone he’d never be willing to lose. He loves him for the arrogance that borders on artistry, for the mind so sharp it could cut through heaven’s pretensions. Aventurine has gambled his soul on lesser things before, but never on someone who could see through every bluff and still choose to play the game.

Summary
With Ratio’s own shirt was gone, his bare chest was exposed to the cool air of the room, his arms were now pinned above his head by one of Aventurine’s hands.
And then, dangling from the other, swinging gently from two fingers, was a pair of ridiculous fluffy pink handcuffs.
Aventurine leaned down, his breath ghosting over Ratio's lips. "Happy anniversary, Veritas," he murmured, his voice a low, seductive purr. He let the cuffs brush against Ratio’s cheek, the synthetic fur ridiculously soft. "I thought we could try… raising the stakes tonight."

Summary
Now, Aventurine isn’t a doctor, but he’s pretty sure that blood is supposed to come out of him when getting a blood test. Nothing is supposed to go in.
“…Doc?”
Something isn’t right.
Or:
Aventurine requests Ratio's assistance in helping him get over his past trauma with doctors in the only way he knows how. Sex.

Summary
Aventurine notices that his partner mood was off and figured that it has something to do with his ex. So what’s a better idea than to put a leash on Ratio and praise him?.
-

Summary
The entire meeting can be summed down into a few key points, which Ratio doesn’t even have to make a note of because it’s stupidly simple.
Find a small community of the nomadic Avgin, follow them and attempt to communicate with them, and if that fails, simply trail along with their group and learn as much as possible about them from mere observation.
Or: Ratio is invited on a research trip, to try and find out more about the Avgin of Sigonia. He does not expect for it to go as well as it does.

Summary
“Veritas. I-I think our mating is sending me into overdrive. I’ve never felt like this during a heat before.” Aventurine sobbed the words as he rode Ratio.
He thrust into Aventurine, making sure the whining blonde could feel his cock ram against his cervix. He kept a fast, brutal pace.
When he felt his knot begin to inflate, he grabbed Aventurine’s jaw, keeping their eyes locked on each other. He pounded into his mate with a force that caused the bed to slam against the wall.
“I'm going to cum in you, Kakavasha. I'm going to fill you so much you'll feel it in your throat. You'll never be able to get my seed out of you. Every time you walk around, you'll feel the traces of myself inside you.”
Ratio slammed in one last time before nesting himself deep inside Aventurine’s wet cunt, his knot inflating.
He bent down, licking the shell of Aventurine's ear as he hotly whispered, “Do you feel how much I'm cumming inside you? Can you feel how much your body is expanding to accommodate all of me?”
Ratio stroked his hand over Aventurine’s womb as the heat-addled blonde cried out, “Yes! Goddess, yes,” before clenching and spasming on Ratio's knot, orgasming himself.Series

Summary
Aventurine attends a party full of IPC members and executives. Despite his hyper-vigilance and carefulness, someone slips a drug into his drink. Being revictmized despite all of the money, power, confidence, and charisma he's gained over the years hurts in a way he didn't know it could.

Summary
He tilts Aventurine’s head back, slots their lips together again, but it doesn’t smell as heavy of smoke anymore. Doesn’t taste like wine or weed when their tongues brush carefully. Tastes a lot more normal, like it could be a normal occurrence. It’d be nice if this were normal. Aventurine would like that.
But that might require a longer conversation… and maybe more wine.

Summary
The first time Veritas had fallen into bed with Aventurine was at one of the IPC’s annual galas. They had both been drinking the whole night, although Veritas had only had a few glasses of wine whereas every time he saw the gambler he had a different colored cocktail in hand. Still, when Aventurine pulled him aside later that night, Veritas had a vivid sense that he was still somehow tipsier than the gambler, feeling somewhat lightheaded as Aventurine grabbed him by the wrist and dragged him out of the main hall into one of the attaching corridors.
“Where–” Veritas’s dress shoe caught on the carpet and he stumbled awkwardly, only catching himself at the last minute. “Where are we going?”
“The whole building is closed for the day. I’m getting tired of schmoozing and socializing, aren't you?”
Veritas’s mind felt as though it was running slowly, like a computer with too many applications open at once. “I… suppose so,” he agreed.
“Then just follow me, alright?”When Aventurine gets bored at an IPC party, he pulls Ratio away to indulge in a different kind of entertainment.

Summary
''But Doctor, look at the mess you’ve made of me…'' he purrs, grabbing Ratio’s hand and placing it in his crotch. It feels warm, wet, and decadent ''You must take responsibility.”
Ratio breathes in at those words, fighting the urge to pounce and indulge in something that won’t end in just an hour, or a single round.

Or... Aventurine riles Ratio up so much, he ends up spanking his pussy.
