I'm really looking forward to one of my ultimate fantasies which is to be suspended naked upside down and then forcibly dunked in a full bucket of vile piss.  Of course with my mouth held open with a dental gag.   This is going to be one sadistic punishment.

Initially my mistress will beat the life out of me on the context that saying mercy will result in dunkings.  Then I will be dunked at least 50 times whilst being whipped.
