I'm afraid, there aren't any
Just found this one and read all of season 1, and it might be a bit uncomfortable because it does get a bit violent since bottom is a masochist, but there is no rape (in one instance, top lost a bit of control, but as soon as bottom used their safe word he stopped)
BTW, in English is barely at chapter 8. I read the whole season in Spanish just in case you’re wondering.

I read most omegaverses and MOST of them are contain rape bc authors fantasize it and many readers eat that shit up. I would recommend avoiding reading in the omegaverse category if you feel uncomfortable abt rape but I had recommend some that contain no rape, "December" , Sayonara Alpha", and "The Origin of Species" but i was thinking whenever not to recommend the last one since there is blackmail but it aint it even that bad tbh but since it rape free since omega does give his consent and was first one to ask to do so with him

and

and lemme know what u think, they both have nontoxic alphas and omegas i'd consider power bottoms and i don't think there's rape outside of the main couple in these
any rape-free-omegaverse recos?
