After enrolling into an exclusive academy, nothing prepares Densuke for his membership in the mysterious Eiken Club. Strangely enough, all of his fellow members happen to be extremely busty females who enjoy nothing better than cavorting around in skimpy bikinis! Despite the constant visual distractions, Densuke only has eyes for the shy and beautiful Chiharu. Unfortunately, all of his attempts to get closer to her backfire and inadvertently make him look like a pervert! Of course, it doesn't help that the Eiken Club's activities are intensely erotic and that Chiharu's younger sister keeps trying to get Densuke into sexually compromising positions! To further complicate matters, Densuke soon finds out that he's not the only one vying for Chiharu's heart! Based on a manga by Matsuyama Seiji. First time in HD on Blu-ray and remastered for DVD.
