I remember a scene from each of them.

The first one: for some reason Rin and Sess are in Kagome's time. Sess decides he need's some time in his true form and proceeds to take rin and kagome to an uninhabited island so he can change. kagome and rin play in the water and then settle down for a nap against him. later on sess retransform into his humanoid form and kagome encourages him to play in the water with her. all three of them go back to the feudal era eventually.

The second one: Kagome returns home but well acts up and sends her a number of years past the feudal era so that when she returns she finds the western lands war torn and that she is needed to rescue a number of people from the enemy I think that shippo, inuyasha and sess need rescuing. I know that kagome leads a rescue group of youkai to where the hostages are being held.

And third: Inu thinks that he can take both kikyo and Kagome as his mates and Kag tell him no and he attacks try to force mate her but sess saves her because what inu is doing would bring dishonor upon the daiyoukai house

If any one can help I would appreciat it. Thanks

Number 2 sounds like Sunset love by Aurora Nyte

Number 3 I could swear I have read recently, there are a few like that

The first is one of my favorites:

Triple Threat by Irulanna
Sesshoumaru makes an...odd demand, and Kagome must comply to save the lives of everyone she holds dear.
Inuyasha - Rated: M - Romance/Adventure - Chapters: 21 - Words: 55,787

Excelent fic, and I higly recommend reading Strange Fate too, also by Irulanna.

The third one almost ring me a bell... Maybe something by Danyaelle-sama? Well, let's see if someone else knows.

Allyonora thanks for helping you were right about the first one, it is Triple Threat. The scene I described takes place in chapters 10 and 11. So Thank You very much

Glad I could help!
