Ok so I just finished reading Captured and Trapped by sweetest angel (Rated MA), and it brought to mind another fic that I can't remember the title or author to, so depressing
So here is what I remember:(warning some graphic description!!)
Kagome and Sesshoumaru have been captured and are forced to share a cell by Naraku. He keeps taking Kagome and torturing her, possibly Sesshoumaru too. One time he whips her back so severely that its basically mincemeat, Sesshoumaru has no choice but to treat her himself, he has to cut loose the hanging skin pieces and then proceeds to lick her back to clean and help accelerate the healing. The purpose of the whole scenario if I remember correctly was for Sesshoumaru to become possessive of Kagome so he would lay claim to her. Which he does and then they manage to find their way out or Naraku lets them be found by Inuyasha and the gang, at which point Sesshoumaru refused to let Kagome go.
Hopefully I'm not meshing two stories into one, and I also hope this is enough to help someone help me find this fic!
