Summary
Being with Superman meant that Lex Luthor had to put up with stress, inconveniences and general weirdness — but it also helped keep things interesting over the years, allowing him to get creative with their ever-growing list of things to try in the bedroom.
So, when Black Kryptonite split his lover in two, Lex couldn't pass up the opportunity to check a couple of things off that list.

Summary
He sets the empty glass down on his desk, and stares at it for one long moment. Finally, he admits it: “Yes.” There’s no point in lying. “Yes, I’m in love with him.”
The confession, unspoken until now, feels like a wound exposed to the elements—tender and scratched raw.
He turns to look at Selina properly, easier with the words already said. She doesn’t seem surprised, still sporting that watchful expression from earlier. He searches her face for jealousy, and though he spots none, he still rushes to add, “But it doesn’t matter. He’s in love with Lois Lane.”
(Bruce admits to Selina, his lover, that he’s in love with Clark, but never plans to confess. After all, Clark has Lois. A look at how keeping silent about that through the years of their friendship goes. Featuring: Selina’s intervention.)
For Polyship Week 2025!

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?”

Summary
Tim Drake is a solitary creature, whether by necessity or by natural predisposition. But he’s good at being alone. He’s learned to enjoy his own company, to take solace in his own cognizance. Aided by the brisk air of Gotham’s night air and a thrilling sense of independence, Tim learns that some things feel more special when you get to keep them for yourself. Unaccompanied walks down the school halls and singular movie tickets and dinners-for-one aren’t so bad when he can entertain himself with his own thoughts.
Tim has become so good at being alone, he can almost pretend he isn’t desperate for the unconditional love and companionship that a soulmate would guarantee.
It would be nice, Tim thinks, to have someone in his life who actually wants him. Someone who won’t leave every chance they get. Someone who enjoys his presence instead of merely tolerating it. Someone for whom he isn’t an obligation.
Still his wrist remains blank.
Until it doesn't.

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
Lena realized, with mounting horror, that it wasn't Lex's portal watch; she'd had that in her pocket. That was-
Mercy's lackey flipped the cover open, and just as Lena blurted out a sharp "Don't," he pushed the button.
"You idiot," Lena choked out. "That's my signal watch."
"Signal watch?" said the Child of Liberty.
"Signal watch?" said Mercy. "Signal watch! You idiot," She rounded on the others. "We need to leave, now. Get Luthor and-"
Somewhere in the distance, there was a crash of shattering concrete and a series of harsh bursts of automatic gunfire. Mercy tensed, taking a step from the door as the sounds grew closer. Cracking concrete. Rending metal. Screaming.
"You have no idea what you've done," Lena choked out.
"What do you mean?"
"The Kryptonite in your chest," said Lena. "It's red."***
After Lena betrays Kara and abandons her at the Fortress of Solitude, Kara is again exposed to radiation from Red Kryptonite, unleashing her darkest thoughts and impulses. Will Kara and Lena burn the world together, or rise from the ashes?

Summary
“If I didn’t know better, it would almost sound as if you want to be at my absolute mercy,” Lex says.
And then he proves it by twisting his fingers into Clark’s hair and giving it a sharp pull back. A damning moan tears from Clark’s throat.
“ . . .to be mine.”
Mine. The word sends a surge of desire so strong it makes Clark dizzy with it. If it weren’t for the ropes, for the sharp pressure of Lex’s fingers in his hair, his knees would buckle, sending him kneeling at Lex’s polished oxfords.
“Oh, Superman.” Lex says with fond condensation, the name clanging like a wrong note. “Your body betrays you.”

Summary
[“Dad, why’d you go so fast? That was dangerous!” Jon yelped. Dad looked down at him in confusion, before zeroing in on Jon’s left hand, still gripped tightly on the ladder’s edge.
“Did you stay to hold the ladder for me?” Dad asked. Jon could feel himself blush as he looked down at his toes.
“I didn’t want you to fall."]

They all thought Morgan Edge would go after Jordan.

Aw ow wow. Sweetens u up, throws you in the oven, then feeds you delicious baked good salted with tears and maybe even a slight dose of poison almost like some way to fatten you up before throwing you in the oven again but luckily the oven break down but I'm still left clutching my stomach from the sweet poison. That's how it feels cos god this is well written and an absolute gorgeous fic oh poor baby the family feels sprinkled throughout the torture just makes it hurt more and god the way Clark searches for Jon goddamnit how do u throw knifes while I'm in the oven but I'm glad there's still a happy ending, even if Jon will probably take a while to recover

Summary
"Okay," Alex nodded sadly, glancing back over at Kara before extending her arm to Kelly. "We need to surround her with all things Kara for when she wakes up, we need her to know it's real. All of you—start thinking of things that will help bring her back to us."
"She's home, Alex," Kelly's smile radiated through the sorrow as Alex collapsed into her embrace. "She's home."
"Y-yeah," Alex sniffled. She knew it to be true—but it didn't feel like it. Not yet.

XStarts with my take on Kara returning from the Phantom Zone after being forced there by Lex, except she didn't reunite with her father (because I can't be bothered to explore that), so she spent the time alone (much longer here than in the show) and it's really messed with her head.
The story explores Kara's struggle with her Supergirl identity as she battles with emotional trauma, alongside her developing relationship with Lena.
Enjoy! Oh, and there will be smut.

“This is my city,” Bruce growls. Some of the flush has gone from Superboy’s face, replaced with a sickly sort of green. The kryptonite is definitely affecting him. “Not Red Robin’s. If you’re in this city, it’s with permission from me.”

Summary
Then he took a deep breath and he changed. He ironed out every fold in his posture and his face until he looked like Superman again. His shoulders were broad, his gaze was confident, and his smile showed no sign of embarrassment or fear.
It’s genuinely uncomfortable to watch.
Especially since Bruce knows that change. He’s seen it in the mirror before entering parties or nightclubs. He’s always referred to it, internally, as 'putting on my better face.' The façade is his least favourite part of the day, ranking just below 'getting punched by supervillains.'
The idea that Superman is just Kal's better face, that would explain a lot.
It would also mean Bruce isn't alone.
