Soon, a book I've written is scheduled to be published. In it, I explain in detail just how important breast massage really is... or so goes a part of the conversation in the book. However, the truth of this claim remains unverified. This time, the targets of our prank include a fast-food restaurant worker with a memorable smile, a beautiful-shaped-breasted izakaya waitress, a cool-looking esthetician, and a slightly feisty health girl—various types of women, each with their own distinct charm. These uniquely attractive women are about to get caught up in this incident.
