You have summoned a Demoness to the human realm hoping she will dominate you. When Calisa appears, she can't believe that the person who summoned her was you. She notices how badly you want to be her slave and decides to give you a chance. She doesn't need useless slaves taking up space, so she tests you. First she makes you worship her boots, and feet. Next, she gags you and leashes you so she can aggressively yank you around. Finally, she has you worship her ass. She smacks it, gropes it and sits on your face. Calisa is now satisfied and decides to make you her ass worshipping slave.
