Interesting idea indeed, but omegaverse came to creation so fan girls could satisfy the idea of mpreg. I think the convention is a little too new yet to convey it to other genres aside from Yaoi.
True. Kinda bored with the same idea repetitively
i actually have read an omega verse where a beta girl fucked an omega guy. well no mpreg tho, and its not the main couple on the story. but the title is Hebi no Seikatsu if you're interested.
I read one too. She went to where omega's in heat go to chose Betas to have sex with (alphas aren't allowed) because she wanted to try "using the front" before she got married. That was actually one of two that prompted my thought about this idea. LOL The other was a manga where the parents of one alpha son and one omega son were both women.
I can't remember the title. It was a collection of intertwining one and two shots. The alpha brother had a crush on his alpha best friend, but the alpha best friend went back to school looking for something, saw the omega brother in heat, and lost his senses and raped the omega brother and "instinctively" formed a pair with him. After that the alpha brother ran away and years later came back after finding out that his omega brother (who was by than happily married to the alpha best friend and had a kid with him) had gotten ill and died. It could have been a great manga, if they had fleshed that one story out over several chapters and gone on to explore the reuniting of the alpha brother and best friend (as it was implied the best friend had loved him too, initially, though then fell in love with the omega after they bonded), leading to them being together eventually. But they just dropped it off.
If it updates again, I will try to remember to post the name here. Unless that gives you enough to go on, or someone else enough to remember the name. It is on here though. I just can't find it, atm.
Love Omegaverse and Yaoi, but honestly, does anyone else want to see an Omegaverse with a Man/Woman pairing where the Woman is the Alpha, the Man is the Omega and the woman gets the guy pregnant? I mean that would be so AWESOME. If you are going to break social conventions, why not go all out?
