The girls often rename their male pets when they take ownership of them. It's almost like they are branding them, customizing their male slave to their personal taste. This slave gets loaned around quite a bit and is used regularly by the girls so he will happily serve Lyla as a good male should. That's why he sits there quietly and obediently as Lyla tells him of the tasks he will be doing as he signs a new slavery contract. Oh, and his name is now Fluffy.
