I'm just looking for a cute/sweet k-on! yuri doujinshi

The one thing I want to specify is that it not be hentai-
I don't care if things get really heated or whathaveyou; but Im mainly looking for plot;
--something with more substance than just "oh mio i love you, lets f**k-" glomp
...like maybe them just discovering their feelings or something.

other pair ups are fine too- but I would strongly prefer mio and ritsu.
