Indentured Servant
A submissive, toothless but otherwise denture wearing, geriatric female that willingly submits to her Dom by performing sloppy, wet, toothless head aka Hot Gummy or Underwater Gummy.
Frank's volunteer work at the local geriatric center and swim complex enabled him to regularly satisfy his need for Dom/Sub relationships and feed his penchant for toothless head from a number of indentured servants.
Indentured Servant
A fancy way of saying a slave
Barney the butler isn't a slave, he makes 1 shilling every 2 months, he's an indentured servant.
