Looking for an old comic/sequence

So I took a mental stroll down memory lane earlier this evening and this comic/sequence I remember seeing some time ago jumped out at me. I can't remember all that much about it but I do know it was by a well known artist, it used to be on Deviant, and it was greyscale or used a lot of darker colors. I don't think what I'm looking for is ancient (late 90s) but it is old (2007-2015) I've turned both Deviant and the gallery here upside down with no luck.

The sequence was about a female spy/assassin who saves either a hostage or someone else from her target before using inflation to kill them. Said other person/hostage asks her how she started using such an odd technique. So the spy/assassin describes this past scenario where she's fighting with another woman and at some point during the trading of blows her opponent loses her balance and falls ass first onto a sprinkler head in front of whatever building they're fighting near.

The next couple panels are her opponent filling with water till she bursts while the spy just watches it happen mesmerized. At one point water starts to come out of her opponents nips and mouth to help with the detail of how much pressure she's under. That's all I can recall.

I'm not sure why but I'm really starting to think it might have been one of Kuumuzu's old pieces but they moved on from fetish art a while ago which explains why the hell I can't find it.
