Totally recommend bea_recs. She has rec lists for a TON of different fandoms (she even has an H/D one that I still need to check out). She doesn't usually say why she's reccing something, but I've gone through her lists in multiple fandoms and they've all been pretty solid fics.
Title: talk to me
Word Count: 1,749
Content/Notes dirty talk, implied bottom!steve, talk of switching
Summary: “I was offering to talk dirty to you so you’d stop thinking I was such a stick in the mud.”
Tony considers. Steve’s from the 40s, he assumes dirty talk back then wasn’t as graphic as it is today. “Go ahead.”
Steve cocks his head at him, lets his gaze linger on Tony’s mouth and the exposed collarbone before saying, “Sometimes when you’re doing tune-ups on your armour I think about stripping you out of it and fucking you against the desk in your workshop until you scream for me.”
"Holy god," Tony hears himself say, and Steve grins before continuing.
LOVE the dirty talk and super fun twist having Steve being the one doing the sexy talking!
Title: Spoiled Rotten
Word Count: 2,551
Content/Notes established relationship, daddy!kink, bottom!steve, rimming, felching, face-fucking, dirty talk

Holy shit this fic killed me with the hot. Fucking dead sexy daddy!kink fic with a wonderfully playful vibe between Steve and Tony.

Title: Into the Fray
Author: miss_aphelion | miss_aphelion
Word Count: 31,779
Content/Notes AU: Fusion, AU: No Powers, AU: Omega!verse, alpha/beta/omega dynamics, alpha!erik, omega!charles, hunger games fusion, bottom!charles, first time, marriage!fic, attempted rape/non-con, arranged marriage, x men first kink
Summary: Every year, two alphas are chosen from each district for a fight to death, and every year, a single omega is chosen to join them in the arena as the prize.
Erik Lehnsherr's name has been drawn to compete as an alpha tribute and he is set solely on survival, but he hadn't exactly counted on Charles, the mysterious omega tribute that isn't playing by any of the rules. Hunger Games AU.
I've read a lot of Hunger Games fusions in multiple fandoms, but I think this might be my favorite. I love how the a/b/o dynamics are woven into the story, it give it a really unique perspective. All the characters were incorporated brilliantly and the relationship between Charles and Erik was just wonderful.
