But failing to find interest in any of them, he targets three special girls – loosely called the ‘Holey Trinity’, attendants of the top grade school Anal Academy – and resolves to plunge into the deepest parts of their minds – and other cavities. Unfortunately for Hora, these girls aren’t going to be easy pickings!​

In it, the player's character can explore an island in an unspecified body of water, exploring the nature, ruins, and the titular "High Tail Hall", all while seeking intercourse with the furry characters on the island.

In a small apartment complex… The sort that might exist anywhere… Our protagonist is a grocery deliveryman whose polite demeanor and pleasant smile have made him a bit of celebrity around the complex. But his smile is not as innocent as it seems… for this deliveryman has an ulterior motive–sampling some of these finely-aged apartment wives! Kaori, who positively overflows with mature sexuality. Ryoko, who while plain to look at, is possessed of a hidden lust bubbling underneath the surface. And Mayumi, a woman still nursing her newborn child, with enough of a chest to make our hero weak. Their husbands can no longer satisfy them, so now it’s up to you!
