It's unfortunately not an omegaverse story, but it features a sort of werewolf who goes into heat which triggers their relationship. one of my favourite mangas.
Use the tag search and write omegaverse, most of the time the uke will go in heat
I mean it's pretty much every omegaverse yaoi.
Do you know any yaoi mangas with omegas in heat? Just like "Love is an illusion"
