I might be wrong, but I think that's Harusame from Kantai Collection. So add Harusame and Akebono together in a search on Pixiv, like I've done here: http://www.pixiv.net/search.php?s_mode=s_tag&word=%E6%98%A5%E9%9B%A8%20%E6%9B%99
Note: I'm probably wrong on who the girl in the picture is, so look through a bunch of other pink-haired Kancolle girls and hope she turns up.

Don't know which one, but it's in there.
(Yes they're non-H doujin.)

I knew it wasn't Harusama. My bad.
To make up for it, the panel is in this one on page 7: http://g.e-hentai.org/g/797673/fd1472ea42/
These all seem to be hilarious/silly though.
