A lesbian ritual in which a lesbian dominatrix urinates into an enema bag and then immediately inserts the enema tube into her lesbian slave's anus and releases the full contents of the enema bag into her slave's intestines.

Or, sometimes a funnel is inserted into the slave girl's anus and the lesbian dominatrix urinates directly into her slave's rectum.

In either case, the maximum temperature of the lesbian dominartrix's urine is retained, thereby the name "hot piss enema".
