There's a continuity error when MC is serving Aiko and Nara. Aiko makes MC eat from a dog bowl under the table, and then between the line "Look how her gaze wanders to our feet..." and the next page "Aiko at that moment takes off her stockings and lifts one of her feet and brings it closer to you..."
MC's outfit suddenly changes! Was maid outfit with white stockings and suddenly becomes something with hotpants and black stockings. It stays that way for several pages before suddenly reverting to the maid outfit.
