The Eiken Club. The activities of this club are shrouded in mystery, all the members are excessively busty, headstrong female students, like Shinonome Chiharu, the top scorer in the entrance exam.
[UPDATE1] By reader request, this fanservice compilation has been re-uploaded and blog post has been updated. delmogeny may have retired a long time ago but his fanservice compilations still continue to be popular… And a big tip of the cap to @Racan for having saved this comp for posterity! It was a big help!! Thanks!!!
[NOTE1] No nipples unfortunately, but there are a lot of nipple bumps…
