I'm looking for an erotica that I read probably around 2010 or 2011.

It was a series of short stories, about a club that tortures young women in different ways, with the common denominator being that at the end of each episode, the club members gather in a circle arounfd their victim and kick her to death while wearing steel-toed boots. And in one episode, the intended victim - instead of being scared and trying to get away - she gets wet and eggs them on and masturbates, and so instead of killing her, she becomes a member of the club.

Does that ring any bells for anyone? I seem to remember that it was hosted on ASSTR, but the search function on the new repository is broken :-/
