One of the nastiest scenes in which a young girl is disciplined by her mother via forced enemas is seen in 'SYBIL', starring Sally Field.
There is a scene in the foreign movie, 'LEOLO' of a son being chased by his father, who is holding a bulb syringe behind his back. The boy obviously is aware of the routine.
The film 'NOBODY IS PERFECT' starring Doug McClure has a scene of a corpulent female navy nurse about to give a male sailor a good flush with a bulb syringe.
In 'KINDERGARDEN COP' it shows Carrol Baker at a Pharmacy checkout getting ready to pay for an enema/douche kit, pressumably to use on a boy she had kidnapped.
The french film, 'DIARY OF A CHAMBERMAID' shows the mistress of the house preparing a douche using an old enamel can hanging on the wall, equipped with the typical European style black nozzle. It stars Jeanne Moreau.
There is a brief scene in 'MIDNIGHT COWBOY' when John Voit as a boy is given an enema by his grandmother. I wonder if it was for punishment since Grandma was brandishing the larger douche nozzle.
There are hundreds of films about enemas and douching in the adult film trade of which
most are boring, poorly scripted and badly acted. The one gem that stands out is the 1976 film, 'THROUGH THE LOOKING GLASS' starring Jamie Gillis. It has an outstanding douche scene performed by a classy attractive lady inside a posh bathroom in which she uses a yellow latex folding syringe.
