Hi! Can you rec your best explicit fics set during the "finding the mutants" segment of first class? Also do you know any (also explicit) fics where Erik and Charles are kind of like fuck buddies or have casual sex before it gets serous? (Also preferably first class) thanks! Love Your page!!
Okay so three immediately sprung to mind with that description:
Good Boys by zamwessell(greencarnation)
Summary: Charles has always been a good boy.
Warnings/Rating/Word count:first time, road trip, 1960s, NC-17, 34,997 words
My Opinion: the description doesn't give you much but it's basically Erik slowly working on Charles through the duration of xmfc (mainly roadtrip) and getting him to let go of the illusion he needs to be heterosexual and stuff. So basically you've got Erik seducing Charles and then things get heated. I like it! Fits probably the most with your description.
Awakenings by fanfoolishness(LoonyLupin), LoonyLupin
Summary: Erik and Charles discover new insights into each other's abilities, even as Erik tries to hide his attraction to Charles. Charles doesn't make it easy for him.
Warnings/ratings/word count: time-travel, implied mentions of genocide (pre-story), NC-17, 12,882 words (part 1)
My opinion: I feel this is mainly what you were asking for, a fall in love type fic set during the road trip. I like it but it’s not the best written on this list.
Hollow Minds and Dead Souls by helen78
Summary: When Charles and Erik take a portable version of Cerebro out to New Mexico as part of their mutant recruiting trip, they aren't expecting to find out the town's falling victim to an epidemic. But things are far worse than they seem, because this is no ordinary virus. Will Charles and Erik find their way home in time to help save the world... from zombies?
Warnings/Rating/Word count: zombies, gore, first time, a bit of horror, zombie apocalypse, NC-17, 54,163 words
My Opinion: A bit of a deviation for what you were asking but it’s set during a roadtrip and has them falling in love and damn this is well-written, I mean everyone should read this one.
Okay so these are more road-trip PWPs
Trip and Stumble by doctorcakery
Summary: He was honestly surprised that Erik decided to stay. Taking a look at his mind didn’t mean he knew the man, and he’d carefully kept his thoughts to himself after their talk the night before, wondering as he went to bed what the next morning would bring.
Apparently it’s travelling across the country with an angry, dangerous, German metal-bender. Life is fascinating.
Warnings/Rating/Word count: road trip, NC-17, 2715 words
My Opinion: My notes for this fic were "roadtrip porn, tastefully done."
By Way of Pain by UtterlySorbine
Summary:
It wasn’t till they got back to the hotel, and he was watching Charles gingerly clean the blood from his split lip, that Erik finally broached the subject.
“Did you enjoy that?”
Warnings/Rating/Word count: BDSM, fight, punching, painplay, roadtrip, NC-17, 2,501 words
My Opinion: Okay so this is basically road trip smut but for anyone into the painplay stuff.
Climate Control by Lolafiest
Summary: Charles needs a little help winding down after they discover Angel.
Warnings/Rating/Word count: Explicit, 2049 words
My Opinion: Cute cute for a pwp.
Does It Feel Like This When by helen78
Summary: Erik keeps everything -- body, mind -- under wraps, leaving Charles no choice but to find other outlets for his desires. When those desires cut a little too close to home, though, everything comes out into the open.
Warnings/Rating/Word count: rough sex, jealousy, angry sex, Charles/other than Erik smut, NC-17, 16,800 words
My Opinion: Very possessive Erik, like woah. See because Charles doesn’t get the feeling from Erik that Erik wants him he finds randomers and you can imagine what that does to Erik….
This is not 100% what you asked for (smut isn’t super explicit but… road trip fall in lovingness)
Timeline by Unforgotten
Summary: After Magneto of an X2-ish future succeeds in the unthinkable, Charles sends his consciousness back to 1962 to guide Erik away from the path that will lead to the genocide of the human race forty years hence.
Charles knows that Erik has always loved him, and intends to use this knowledge + sex to seduce Erik away from his ideals in his youth.
There’s no way this well-thought-out, sensible, debugged and 100% bulletproof plan can possibly go wrong.
Warnings/ratings/word count: time-travel, implied mentions of genocide (pre-story), NC-17, 12,882 words (part 1)
My opinion: Techichally a series, the first part called Replay, it’s the perfect fix-it. It’s not major explicit smut or anything but the story is beautiful.
