This mistress wanted to find out how much fun spit fetish could be before she decided to try it out on a full scale. She tried it on a doll to test it out before she did it to a slave. She spat on the doll and it was interesting. She simulated a slave licking her soles by rubbing her shoe on the doll's mouth. It was interesting enough that she decided to look for a slave and do the same to him.
