Prompt Fill for Gabs: Redk!Kara wanting it fast and hard and lena fucking her gently until she's in tears? With lots of praise kink pls
*OR*
Under the effects of Red Kryptonite, Kara has to be kept somewhere secure. The L-Corp Laboratory is about the only location with enough lead lining to hide her heat signature while the DEO worries about bigger threats. Kara’s frustrated arousal and darkened mood is nothing compared to her girlfriend, Lena Luthor’s.
There’s a dark and evil side lurking inside Lena too. Always there, always out of sight. With Kara under the influence of the Red Kryptonite, Lena finds herself indulging in her own primal dark side in order to quell Kara’s own.

Summary
It's a story where Barry Allan and Clark Kent hangout and eat a meal together, but then they are needed to save people's lives. During the team up, Clark gets infected by Red Kryptonite, which slowly changes his behavior and as Barry tries to take Clark to the Fortress he begins to notice the changes in Clark behavior. Superman gets aggressive and wants to hurt Lex Luthor, but Flash tries to calm him and stop him, which is when things get feisty.
The characters are from the comics version and not from CW or DCEU.
I do not own the characters. DC comics does.
A story my friend, Kyran, and I have been working on.~
Enjoy~ Please leave comments below. -

Summary
Clark puts on a red kryptonite bracelet to give him the strength to stop Lex. But as it transpires, what he wants most isn't to kill him, it's something infinitely more damning. What if Jor-El's artefact really did grant control over the Traveler? And what if the story of Sageeth and Naman isn't all it seems?
(Clark has a dark side that he can't face. Lex has more potential for good left in him than anyone knows.)-

Summary
The kiss was heated, like the very flames of the sun licking at his mouth. It was absolutely nothing like how Bruce imagined kissing Clark would be, all hard edges and power, and none of the gentleness he knew so well. Still, his body instinctively lit up as the press of Clark's body against his felt so right, even as his mind screamed all of the ways this was wrong, absolutely wrong.
In which Clark is acting strangely, and Bruce deducts that he must be under the influence of red kryptonite. Fortunately, he has a plan. Unfortunately, the plan means walking the fine line of playing along to save his friend or surrendering to his own desires.

Summary
“I do know you.” Supergirl’s voice is soft and tender, a contrast to the wildfire that blazed in her blue eyes. “And you know me. Look at me, Lena.” Lena complies, locking gazes with Supergirl. “Really look at me.”
Lena notes the pleading tone in the hero’s voice and takes a moment to look deeply into those bold, azure eyes. Even though they’re intense, even though they’re filled with an anger Lena has never seen before, they’re also familiar. Why is that? This kind of familiarity comes with knowing someone intimately. She doesn’t have that kind of relationship with Supergirl, it’s strictly business.
No, there is only one pair of blue eyes Lena has spent what feels like a lifetime staring into. And with a breathless gasp she realizes, she’s staring into them now as well. They’re darker than normal with a hint of mischief, anger and wickedness but they’re still her eyes.
Kara’s eyes.
Kara is Supergirl.
AKA Kara comes into contact with red kryptonite instead of harun-el during season 4

Summary
"Jesus, Superman, don't treat me like I'm a child. You're not my fucking father!”
He realized what he'd said a second too late. It was a default mode, when he argued with Bruce, to remind him that he wasn't his father, he hadn't been adopted, he'd been easily replaced, there was nothing between them. Nothing.
And never mind his hurt feelings, and the loss he felt. Bruce had made it clear what he thought of their relationship. And Dick wasn't a child anymore.
He was almost ashamed of his outburst when Superman sneered dangerously, "You're right. I'm not your fucking dad. I'm fucking your dad."
(Sooner or later, they'll have to find a way to prevent so many aliens from obtaining kryptonite and its variants. But for now, Clark can uninhibitedly get some things off his chest with Dick.)

BirdFlash Loops by Ikibli
Fandom: Batman - All Media Types, DCU, Green Lantern - All Media Types, Superman - All Media Types, The Flash - All Media Types
11 Sep 2025
Summary
Basically Infinite Loops with Wally and Dick as co-anchors.
This takes place in the same continuity as the HalBarryIris loops, and any loops where Hal, Barry or Iris are looping will also be a part of that series. Same with the Flashfam loops(Bart, Max, Eobard and Jay) and the Batfam loops(Jason, Tim, Damian, Stephanie, Duke, Cass and Bruce).
The Bluepulse Loops are a seperate continuity, though occasional mixups do occur(raising many existential crisises, since there are two seperate looping Barts).
Can be read in any order.- Words:

Summary
“So basically, it turns off the part of me that gives a damn about consequences.”
Bruce nodded. “Exactly. It also doesn’t create new thoughts or makes you feel anything new. It just removes the reasons you don’t act on what’s already there.”
Clark was quiet for a moment.
Then: “Oh,” he said softly. A glint sparked behind his eyes. “Well then.”
He moved.
In one fluid step, he closed the distance between them.
Or, Clark is hit with red kryptonite for the first time, and Bruce has to deal with a version of him that doesn’t know how to lie, hesitate… or hide what he wants.

Summary
Lena realizes something is wrong as soon as she steps inside the penthouse.
It’s not the shattered glass that glitters like fresh snow in the moonlight, nor the wind whistling through the smashed french doors in the living room. Her eyes take all of that in - and of course it isn’t normal - but they halt on a patch of shadow darker than the rest.
OR
The one in which Lena returns home to her wife after a long day at work, and finds a stranger instead.

Summary
Then, Clark’s eyes met his, and he pulled away so quickly that the sound of his retreat whipped through the air. His face, for a moment, was startlingly open, and naked grief cracked harshly through his expression like a fist shattering the surface of a frozen lake. Then, it was gone, and the slate was wiped clean as though there had been nothing but a mild smile there since the very beginning.
But Bruce knew what he’d seen.
“How long?” he asked.
Clark’s mouth twisted. “I don’t know why I thought I’d be able to keep it from you,” he said softly. “You know me too well. Was that even five minutes?”
“Clark.”
Clark’s lips turned up into a smile, fracturing his face, his eyes glittering shards of lapis lazuli. “How long for what?” he asked. “For how long we were married? Or for how long it’s been since you died?”

“She kisses me, not knowing that my lips are coated in poison. She pulls back, and I wait with bated breath. Then she smirks smugly and asks, ‘darling, are you trying to kill me again?’”
Second dark SuperCorp AU. Trigger warning for murder, plotting murder, dark/sexual fantasies, sex kinks, graphic descriptions, violence, and altogether just a whole lot of dark themes.
#2 Dark SuperCorp AU.
