Mina's slave is extremely pathetic. Her will do anything to make her happy, even in the bathroom. Mina's slave has just finished cleaning her entire bathroom, and she wouldn't want to mess up his work. Mina has the slave hold up a gauntlet for her to release her golden nectar into. Very humiliating! And of course a slave tongue is much softer than toilet paper. -That is just one of the perks of being a Princess.
