There was a manga about two friends, who weren't the nicest people. I think there was a scene on a party. Somehow they decided to do it with each other. Andy ideas? The art style was very "rich", lots of details on every page. Someting you don't see very often in yaoi manga. The title conisted of two (I think english) words. Thank you!
