All I can remember from it is that kagome, miroku, sango, ans rin were 'friends' but were only really using Kagome for homework help.They plus sesshomaru all go away or something for a weekend and Kagome finds the others engaged in sex (miroku/sango) (rin/inuyasha)and talking about her and how she is a prude and a great way to make others think better of them. So kagome runs away and ends up in the house/cabin that sesshomaru was in. They end up having sex, miroku and nuyasha see them at one point while looking for kagome but don't know that it's her. They assume he just brought a girl with him. Sesshomaru doesn't correct them and doesn't let them know kagome is there when they knock asking them why they care because they were just using her. It's revealed that rin has a cruch on sesshomaru and rin and inuyasha break up.

Thank you so much! I've been searching for days for this fic, whenever I can't find something to read I go back to stories I liked but what do you know I never wrote the name down.
