I started to read this story long ago, but stopped soon since it was unfinished and I though I would wait for the end.
Not much to go on I think the title either have pack or brothers (maybe together?).
Last time I saw it it was unfinished with around 12-15 chapters.
The homepage it was on had gray background (I thinks...)
Don't know the author but there were many other stories written by the same person.
And finally I'm pretty sure it was a spander, since it was all that I read at that time.
I know it is vague, but I would really appreciate any help that that you can give.
Thank you beforehand,
Alterian
Edit: the story is "Hunt brothers" by
