I don't remember what else happens in the fanfic. But I've been looking for it long. Help!.

Kagome is in feudal times, and she can't go home. I think the well is sealed.
She is depressed because the situation with his marriage to Inuyasha, is bad. Inuyasha sometimes isn't a good deal with Kagome, it's rough sex with her, he abandons to her for various days.
Then Kagome goes to the well, and finds Sesshomaru. The demon is aware of the situation, and tells her, that he can please her fully to her and that he is good at sex.
Kagome thinks for a moment, but just as she is crying. And finally, she agrees the proposition. And both have privacy near the well (sex).
Later, she returns to the village a few days. And she meets with Inuyasha, too.
