Finally decided to get off my butt and give translating a shot. I've got a lot of stuff queued up that I may never get to, but I figured I'd start with something simple.
I was faced with two realities in the process of doing this. One, transliterating sex sounds is trickier than it looks. Two, I'm not a whiz in Photoshop.
Anyway, the artist is Error. http://www.pixiv.net/member.php?id=860361
They've got one other work on the site that's been translated, and a look at their Pixiv revealed they've done a number of other brief stories.
