Suddenly, an incredibly sexy girl named Tsukino Kasumi appears in a quiet and peaceful club. She wears tops and miniskirts that clearly show off her body lines, and generously shows off her long legs... The virgin otaku men are simply timid at the appearance of this completely out-of-place princess. "Let me do that too!" she whispers sweetly from close range, and as a result, she joins the club. At a social gathering that is soon arranged, Kasumi plays with the otaku men by casually showing off her panties, and smiles as she watches them bewildered but unable to resist their desires. What will be the fate of these virgin otaku men...?
