I would imagine from the omegas milk, kinda like how female dogs or cats work. Like how cats or dogs dont have any boobs or anything that looks like boobs. Untill they have children they feed their young.
Oh right! Σ( ￣□￣)
It could work..
So now I imagined that their (male) nipples would
grow a bit bigger when they were pregnant.(⊙…⊙ )
The case's solved.

It's yaoi. The readers do not want to see intruding women. But there are women as described in the introduction pages.
Oh right...
Forgot about that.. (=・ω・=)
Looks like everyone in omegaverse is male. So here's the thing. They had no boobs. How could they possibly feed the baby? Only with cow milk? Lol
╮(￣▽￣)╭
Well, I still like this omegaverse idea though
