The first story I thought had the title of frivolous sentimentalities but I can't find it and the second and third have Kagome as a concubine/ bridal candidate/ human mom for Rin in one she works along side Inu to fight void demons and the other she is mom to shippo but has not told Maru that he showed up so he gets angry at her for smelling like another male. If anything sounds familiar please let me know thanks

The first one is Frivolous Sentimentalities by Tally Mark.
I couldn't find it here on Dokuga, but I was able to find it on ff.net
www.fanfiction.net/s/4463099/1/Frivolous-Sentimentalities

It is rated K+ over there.

The other two sound familiar, but I'm not able to narrow them down to specific fics. I'll post again if I'm able to find them.

I think that the third one is Striking Falcon's Second Chance. Rated MA. I think that the part you are thinking of happens about halfway through the fic?

I think both the second and third stories are one and the same. I can't remember the name, and I'm sure it's ongoing, but I remember Kagome was chosen by Inuyasha and taken to Sesshomaru's palace to be on a contest to become a human concubine. In the last updated chapter, Shippo and Kirara make an appearance and Sesshomaru, thinking Kagome betrayed him for smelling like another male, attacks her until he sees Shippo, who is introduced as her son.
I'll try to refresh my memory and see if I can find the story.

The first story is called the Bridal Creed by MoxyMikki

It hasn't been updated since 2011. However, its a good story.

Thank you that's the one I was looking for

Thank you very much I could have sworn it was on this site and didn't even think to check ff.net
