This is the sweetest dream for an ass-lover like me…the rest is on CosplayErotica.com
I wrote a few weeks ago about the CosplayErotica calendar 2012. They used the most popular sets for every month and created a real art work. Here are two pages, the July character is inspired by Princess Kitana from Mortal Combat (model Gogo).
The August page is a Fallout look-alike cosplayed by Alexa. Every month is a different gaming character for real players.
Unfortunately you can not order this calendar, but the cosplayerotica.com members can download it in the members section. I think it is worth of one month members fee. The resolution is good enough to print it in A3 format.
