“Caressing the Nipples of My Hibernating Bear” is about a bear-man named Nowa, who has been living a lonely and solitary existence in a remote forest for years.

As nature demands, Nowa goes into hibernation one unknown November, leaving his protégé, more or less, in the lurch.

And so begins the story of a full-grown bear and a young dog, who seem to be madly in love with each other …
