Hey,

I read an interesting topic few seconds ago and became really curious
The topic was about youkai pregnancy and why some people make the pregnancy shorter and some longer than normal human pregnancy. But there also came an interesting thing up; that youkai pregnancy should be in their youkai form. In other words inuyoukai should be pregnant in their dog form...

Is there even fanfic somewhere out there where this happens?

It's been done at least once that I know of: Warrior's Honor (very MA) by Crystal-Tiger82674
Battle with Naraku is over. Everyone but one is died. Can a lone survivor, carry on with life knowing she survived and the others didn't. Has the fates punished her for something or left her alive for some other fate?Pairings Sess/Kag,Kag/InuTaisho.

There is also Kouga/Kag in there. End pairing is Kagome/Papa. Kagome gives is pregnant and gives birth to pups/cubs in Inuyoukai form for both Sesshomaru and Kouga. There's also non-con that masquerades as dub-con or fine, abuse, violence, kidnapping.

I didn't find this to be a great fic, so it's not a recommendation as much as information.
