I used to always wonder about female alphas and how female x female stuff in omegaverse worked... I remember reading a story one time where the parents were a male omega x a female alpha and the male omega was the one who got preggos and I was like wait what??
Now I know that female alphas have dicks lol

Sadly no I don't (/TДT)/ I would need to go through and re-read all of the omegaverse manga I have read I just remember in one of the ones I read it was mentioned that is how females are able to reproduce. ( ̄∇ ̄")
If I come across it again I will be sure to let you know which manga it was in that they mentioned that.(๑•ㅂ•)و✧

I looked through a bunch of manga and realized the whole retractable thing must of been something I read in an online fan fiction or novel something as I can't find it.
(〜 ̄△ ̄)〜 (/TДT)/ I may have also forgotten it was from an image I had come across a while back this image that does mention it being a part of it so maybe it is part of the omegaverse its just most authors don't mention it or they do a different thing.
Most of the omegaverse read did all mention that the female alphas do have a "thing" it just it only gets erect when stimulated and its usually only mentioned in the intro for those that did mention here are some of the ones that mention the female biology a little bit but only in the introduction. I guess I must have mixed my information when I posted that comment sorry about that misleading comment( ̄∇ ̄")
Here are the omegaverse manga that do explain or offer a small info how females can get another female pregnant but it is very brief and as I said is in the very beginning explaining how the omegaverse works.(⊙…⊙ )
Abarenbo honey (Yaoi) manga
Kashikomarimashita, Destiny (Yaoi) manga ( this one only VERY briefly almost not at all)
Sayonara Alpha
Omae no Koi wa Ore no Mono (Yaoi) manga (this one kind of mentions as a female alpha tries to forcibly mark the omega but fails)
Okusama wa Alpha (Yaoi) manga
P.S here is an image that does mention the retractable 'thing".
