Help me identify doujin. PLEASE!!!

It's been 2 YEARS since I began searching the first hentai I ever read, and now finding it is a matter of honor. All I remember: Its about a blonde pettanko/petite teacher, that in each chapter ends up being dressed in a different fantasy (nurse, maid...)by her coworker. It's VERY focused in comedy, and every chapter is vanilla. I know that its a vague description, but after 3 weeks seeking in japanese sites everyday without THE SLIGHTEST clue about what I was reading, I am REALLY desperate.
:'-(

Dude... You just made my week. And restored all my faith in mankind. Thank you very much!!!!!!!!!!!!!!!!:'-)
May the Force be with you!!
