Gratitude is what Amanda appreciates from slaves. Gratitude for permitting a slave to bask in her feminine presence, gratitude for permitting a male to work for her, and certainly gratitude when she gives a slave pain by shocking his cock. That is because the pain serves either as amusement for Amanda or to serve as correction for bad slave behavior. Whatever the case may be in this circumstance, the slave must still be grateful for the pain because his suffering is giving him a chance to please her.
