Between Friends by erimeows

Summary
It’s a line that they’ve tip-toed far too many times, yet never actually crossed. It’s exciting. Thrilling. Havoc isn’t even remotely uncomfortable, just relishing in the attention from them while he can. It’s likely that, by the end of the night, they’ll wind up in their own hotel rooms- and in the morning, they won’t talk about the wanton looks or lingering brushes of their hands on one another.
“Hey, you two,” Mustang casually starts when the bartender announces that the bar is about to close for the night, his voice not betraying a semblance of what’s to come. “Why don’t we head back to my room for some more drinks? There should be more than enough in that mini fridge to go around.”
“With all due respect, sir,” Hawkeye, easily the smartest between the three of them, interjects after swallowing down a gin and tonic. Perhaps she, like Havoc, has noticed the stolen glances, fleeting touches, and boundary-pushing comments sprinkled throughout their impromptu outing. “Are you sure that’s a great idea?”
And, Havoc being Havoc, he foolishly laughs at Hawkeye’s words with a shrug and says-
“What’s a few more drinks between friends?”

Summary
Alphonse and Edward just found out the real ingredient of the Philosopher's Stone. Next, they want to look into what Dr. Marcoh said: something about finding the truth behind the truth.
But rather than going to the Fifth Laboratory straight away, Edward's automail arm could use some repairs. When they stop by East City and an unsuspecting Edward is suddenly called to the Mustang office at the end of a long day, he has no idea what to expect.
Getting accused of stealing is certainly not on the list. Especially considering he wasn't even in East City at the time of the theft.
Will the colonel believe him? Or is there something else at play here?
(Takes place around episode 7 and 8 of FMA:B)

Summary
Master Hawkeye's daughter was one of those sights that could brighten anyone’s day: almost divine with her golden hair and amber eyes that shone like two ingots in the sun, and although it took him a good amount of time and some stumbles to realize it, she also possessed a golden heart.
And Roy Mustang completely fell for it.

Summary
“Very well, then. If you want to make a game out of this,” Roy pauses, standing from his desk and circling it to the small coffee table in the center of the room. A chessboard rests atop the wooden surface, the pieces perfectly set. “Let’s play.”
Riza watches him as he works, arms still folded, amusement flickering behind her irritation. Her hands twitch, almost like she wants to pick up a piece herself.
“It’s not a game to me, sir.”
“Doesn’t matter,” He smirks, reaching over to tip the black king onto its side with one gloved finger. “Because whether or not you want to admit it, we’ve been playing this game for a while now- and I’ve already won.”

Summary
“Then it seems we all feel the same way,” Roy says with a sigh of relief. “Now what?”
“Well, I suppose we should figure out some sort of… Arrangement,” Riza answers.
Jean practically shoots up from the couch he’s sitting on, his face panicked.
“Wait, I’m confused,” Jean’s voice cracks as he speaks. Roy didn’t think that Jean could possibly blush any harder, but it seems that with every second that passes, the shade of bright red on his face grows increasingly dark. “How the hell are the two of you talking about this like it’s- like it’s work or something? It’s not going to be that easy!”
Riza quirks a single eyebrow and asks-
“Why can’t it be?”

Continental Breakfast by TheySpellAlice
Fandoms: Fullmetal Alchemist: Brotherhood & Manga
12 Dec 2023

Summary
[Cross-posting from ff dot net!] There's a lot to process when Ed and Al finally come home. Named after the Courtney Barnett/Kurt Vile song, this is a breakfast buffet of quick & delicious two-year-gap stories that will eventually take us all the way to seeing Ed off at the station. Featuring automail shop talk, physiotherapy hell, dates gone wrong, career moves, crime-fightin', unexpectedly fancy dinner parties and emotionally significant acts of interior design. Manga-verse, and as aggressively canon-compliant as possible, with a lot of focus on Ed, Al and Winry figuring out how to fit knowing the truth about the Amestrian state into their new lives. See also: being normal, having hobbies, working, interacting with the neighbour kids, unraveling unexpected family secrets, learning new recipes and yes, coping with the longterm impacts of trauma.
There WILL be a sequel (with higher rating) and a companion piece in the same continuity, but this fic will be solidly T For Teen.
