Our little Gotham Family

This is a Omegaverse!
Cory goes into heat and 3 months later feels ill.
What could be wrong?

Just know this is a fanfic. I don't really want this to be real. I respect that these are real people
I'm happy for Robin and Richard. I absolutely think their relationship is adorable. This is purely for fun and nothing else. Robin and Cory, if you see this. Know I'm not doing this to hurt either of you. I'm just doing this to be creative. If you wish I delete this fic I will because it's not to hurt anyone.

To those who think this is disgusting. Don't read it then. I'm not forcing you to read it.
There is: Omegaverse, Mpreg, Graphic Child Birth, Cory is Trans, Poly Relationship.
