Im sure this is a verrryy old story. All I remember is that Sesshoumaru and Kagome are mated and they have one son maybe. An enemy comes to threaten them and they find out it is actually the child of Kagome and Inuyasha in the future. Kagome mistakenly gets pregnant by Inuyasha and she dies giving birth to the child. Sesshoumaru raises him but doesnt treat him right so the son become very resentful.

It sounds similar to this one;
