There are some fluffy omegaverse stories but there's rape in it, regardless if both were unwilling due to the pheromones, or it was someone else who wasn't the main pairing. But wiith no rape? oh boy;;

if you're into furries http://www.mangago.zone/read-manga/pendulum_kemonohito_omegaverse/
kashikomarimashita destiny has rape (not by main pairing) and attempted rape
abarenbo honey has rape too even if they both didn't want it to happen
love shuttle has the omega forcing himself on the alpha even if neither want it
so is megumi and tsugumi during the gym scene
that's why i didn't add them ╮(￣▽￣)╭
Oh my okay I was debating on answering this one cause I don't really know what rape in omegaverse would be.
Hanagara Tsumi by Tsuba Daeki, alpha x omega pairing, the arts really nice and the clothes are really stylish. Seme’s facial expressions are the best, he makes me laugh.
Okusama wa Alpha by Fuyu Natsushita, alpha x alpha pairing. Again really nice art and elements of humour, cringe but still kinda sweet.
From what I can remember there’s no rape in either, the first is still ongoing and the second is completed.
Megumi and Tsugumi which was mentioned in an earlier comment is a really hard one to call on whether it’s rape or not, the whole pheromones thing blurs the lines... yikes lmao.
