Okay I checked out the rest of the chapters just to be sure and that's definitely not it...but they are so much alike I wonder if one is based off the other, because the ideas are the same but I remember the writing to be different and many scences are missing...
Further info I remember. If this helps...
Sess had a posse of Kouga, Bak, Jak, Naraku(I think) and some other boys...
There was a part where Sesshoumaru took Kagome's bikini top and the only condition he gave for her to get it back was to flash him
Ok
that's all I got left
