Genie in a bottle, your wish is my command! Could be anything, could be a series with the same model. Being made to shower whilst being watched etc. In fact being asked to perform any number of tasks all the time knowing from the start they are being watched and no way out, must obey the master. Performed in a genie cusume, at least in the start of the scene, sets up the scenario without too much delay in explaning the relationship between the model and the male.
The trouble with having an open mind others just want to fill it
