Sissy is finished with most of her chores, but Mistress Alegria and Mistress Nyssa continue to taunt her and as a final humiliation they put the key to her chastity device in an ice tray and make her freeze it. She will be locked up for a while. She will only be released when the ice cube melts.......but of course that will only happen after the ice cubes are shoved up her ass to melt.
