The sitting lady in Leodom04 is surely a client.
In 16. we believe we see a madam punishing a toy, perhaps because the toy misbehaved. Or is this entertainment on the small stage in the bar? What do you think?
In Leodom26 a madam instructs a toy selected by two clients, probably watching: "... or else," the admonition ends, and the madam winks at the clients. Needless to say, the madam just loves it and will probably be watching how the clients enjoy their beautiful prey.
