From Tadanohito:

This series is centered around a well-endowed hotel worker and the encounters he has with various guests and employees. Each story could probably be taken separately, so it's not exactly a serial, where each chapter builds on the previous. Because of this variety, there are various types of stories and sex, generally consensual, and involving all kinds of fetishes.
