They get to watch the lines and the wrinkles form on each other's faces; they get to see all of the events that shape those lines, like the way Charles gets a permanent crinkle between his eyebrows from sighing at the prankster students and the way Erik learns to smile so often that he gets proper crow's feet

Charles gets to see Erik's hair go grey, and then white, and he gets to run his fingers through that white hair even when his hands are gnarled and veiny and shake a little bit

They get to play thousands of games of chess together, day in and day out, night after night, until they have difficulty remembering all the rules and they're not as good at planning strategy as they used to be

All of the mutants they help, they get to watch grow up together; they get to see those mutants get married and have children and then they get to see those children grow up as well and neither of them ever has to feel alone again because in finding each other, Erik and Charles started a community that provides them both with more family than they ever imagined having

Hi Anon,

Sorry I haven't read any fics with this premise, but I found a few that might fit your criteria (see below). I've also included a link to a previous post for old cherik fics that you might want to check out!

Rage and Serenity by Lica_K

He still remembered like it was yesterday the first time he looked into those beautiful blue eyes and his heart had broken in a way he hadn't thought was still possible, but Erik should have known better by now that Charles would always find a way to mess with his feelings and make him as vulnerable as a mere human, even if unintentionally. No one knows exactly what happened that day when so many X-Men died and honestly Erik prefers not to think about it because that was also the day he almost lost him. It didn't matter if Charles sometimes didn't recognize him or his brilliant mind was destroying him bit by bit, while Erik was still breathing he would destroy the entire world first for all the suffering it had inflicted on his old friend before death tried to take away the only thing that meant everything to him.

Basically a new version of the events that took place in Logan's movie (2017) if instead of Caliban, it was actually Erik who was protecting Charles along with Logan.

My Empire of Dirt by winter_hiems

Logan and Charles are hiding out in Mexico, trying to forget the pain of the past, until one day two young mutants turn up at their door: Laura Kinney and David Haller.

True friends are never apart, maybe in distance, but never in heart. by TheImpossibleDetectivesAngel 

meet at 17

build school together

build cerebro together

teach together

raise Jean together

then part ways

now this is True Divorce ©

The reason XM: TLS sucks is because of misogyny and homophobia. Those cowards don't have the balls to have Jean as the center of the narrative because it would mean writing a woman as human, not a crazy and delving into her past, which means having to discuss Cherik as parents and mentors and the homoerotic subtext prove… *gun shot
