hello, I'm trying to find this fic!
Naraku pretends to be inuyasha and forces kagome and sesshomaru to impregnate kagome.
Sesshomaru captures kagome and wants revenge for being forced to have sex, but eventually falls in love with her.

Right before she gives birth, naraku, still disguised as inuyasha, attempts to kidnap and rape kagome. They are caught by Sesshomaru and he thinks that kagome is still in love with inuyasha despite being pregnant with his child.

Kagome gives birth and Sesshomaru learns the truth about naraku, but the damage to their relationship has been done.
Kagome plans to leave and take their son with her and sleeps with Sesshomaru one last time.

The following day, she finds out Sesshomaru still loves her, and their night together resulted in a second pregnancy. They move to a new castle together.

If you know this fic, please let me know. I've been searching for a long time.

I think I've read it before but I can't really remember the name. I will try search around for it to see if I can find it.
