Disclaimer :I do not own Inuyasha or anything associated with Inuyasha. I do however own Yume.
OK. Before I actually start writing the fanfiction I want to explain some things. First, Rin does not exist. Instead there is a female half dog demon, half human, named Yume. She looks to be about 18, but of course since she is a demon she is much, much older. There isn't much else to say, except that something weird happens after Yume falls into the Bone Eater's Well, Sesshomaru tries to catch her and they end up in Kagome's time. They are stuck there. Later on, Miroku, Sango, Shippo, and Kilala are transported though the well. The well doesn't work when they try to get back. So basically, the well is malfunctioning, letting people through who shouldn't be able to through and then not letting them go back. Kagome can go back and forth but there is no point without the others being there. If any questions or anything like that come up in the reviews I will do my best to answer them.
