All that walking in the heat tends to dry out Miss Lavey's legs. So when she gets home that is something that needs to be resolved by the nearest slave. She plops on the couch and snaps her fingers, causing a slave to run into the room and kneel in respect to his owner. He turns on the TV for her, then fetches some lotion to take care of her legs. Such a good boy, he is both quick and obedient which is why Miss Lavey keeps him as her pet.
