I'm hoping you guys can help me find an old fic, please! It was an a/b/o fic (I think it was on a kink meme, maybe?) where Charles is an omega going into heat. Erik is not an alpha but he helps Charles through it anyway. I hope that's not too vague, sorry. Thank you for your help!
Not too vague :) I hope this is the one you were looking for:
Untitled Fill by Anonymous [Cherik, NC-17, A/O]
What about a fic where Charles is still an omega, but Erik is just an ordinary beta, rather than an alpha? Just an ordinary beta male, but one who still thinks Charles is gorgeous. How would that work between them?
