The slave auction gallery is installed with a 1 way mirror so the potential buyers can place their bids without revealing their identities.
The girls have been stripped to their skimpy thong panties, labeled with their names for easy identification, the sheer fabric of their panties offering little protection from the hungry eyes of their buyers.
On the other side of the gallery, the muffled screams of the abductees can occasionally be heard among the few girls who manage to wake, unaware of how entertaining and erotic their gyrations in their brief state of wakefulness are to the buyers on the other side of the glass, as they struggle to stay awake. The girls are gagged with a drug soaked cloth to keep them drugged and stupid. After a brief struggle, these girls are forced to watch their humiliating slump back into oblivion, cutely batting their eyelashes and rolling their eyes upward as they pass out from the drugs.
... I did a Hi Res linework drawing of a day in the life of Milla Automata, for those among you inclined to colour, hope you enjoy!
