No one else is in the small courtyard, as the door you came in through is the only one into the grassy area. Clearly this is just some offshoot of addition to the castle that doesn't warrant much attention, so the peasant maids took it over for laundry and maybe some outdoor reading. Saki helping you get the clothes and panties up onto the lines with clothespins, blushing and giggling to herself all the same. She does seem to enjoy her life as she finishes. Asking you if there is anything else she could teach you, wiggling her legs together and blushing some more.
