Yuno x Asta "Yours" (Omegaverse)

Asta one day at the black bulls base starts feeling odd, when he go's to ask Finral for help he nose catch's the sent of Luck who just recently had a baby with Magna, and still has that pregnant sent on him, Asta go's on a rut and try's to attack Luck, Magna being Lucks mate, growls at Asta telling him to back off, but Asta doesn't listen. Right as Asta is chasing around another omega three people from the golden dawn show up Asta picked up the sent of another omega without a mate. Yuno.
I did get the idea of this story from reading a different story, so I hope you like it. :3
