It's surprising that while this was supposed to be a mindless Otaku ecchi panty show it actually turned out to be a pretty good-natured fun show and in a way could be useful for the younger ladies if the information that is discussed during the show is correct. Think about it an easy way to teach kids serious stuff with anime....yeah it probably wouldn't fly.
I know I wasn't excepting much and with little to no coverage by the image boards you would have thought it was a really bad series. However, I think it deserves a better fate than that. It was streamed on Crunchyroll and is still there if you want to check it out but It'll be interesting to see what the DVDs have in store for additional goodies. Oh and yes one last thing...Talking Nipples!
Here's a quick plot summary from Wiki:
The story revolves around Nayu Hayama, who embarrasses herself on the first day of middle school by accidentally showing her adult panties. As two other students, Yako Jingūji and Haruka Shiraishi, hear rumors of her engaging in "enjo kōsai", or compensated dating (which often is viewed as being close to or the same as prostitution), they investigate. They soon learn that Nayu is an 'underwear monitor' who tests new underwear products, and has great insight on what underwear people should wear. Nayu hopes to help everyone get through the vital stage of their life by opening an underwear club
I enjoyed it and I laughed a lot, the fanservice is definitely there but it's not done in a way to be a bad thing in fact more often than not it's either done for laughs or for educational reasons and not in my opinion gratuitous.
This was the only good trailer I could find for it:
