I'm hoping someone can help me find a doujin I saw in a K-Books in Akihabara that I don't know the name of and wished I grabbed. In the new arrivals section, it had three girls on the cover, and the middle girl was blonde with large boobs spilling out of her shirt. It seemed to be a story of the other two girls corrupting the girl in the center. Middle girl had a school uniform on, but the other two didn't.
