The practice of tickle torture has its origins in the Middle Ages, where it was used as a form of punishment. The slave is entirely under my control, with no hope of mercy or redemption. Shackled and unable to escape, the slave is at my mercy as I search for the most ticklish spots and revel in his writhing and screaming. There is no escape for the slave, only the unrelenting tickle torture that I inflict upon him.
