After running an ad on backpage, to pay people $100 or so for being filmed in visit with a mistress . . . actors must be willing to do a golden shower, get caned or both, novices welcome . . .

Film interviews and scenes with 8 to 15 people. Begin with a short interview including why they responded and their experience with seeing a mistress.

Set up for a golden shower and while doing so, let the person know that if he or she opens his or her mouth and drinks it, there will be no caning. (Not disclosed in advance.) If not, he or she will be caned 100 strokes. (The person knew already, before coming, that he or she might be caned at the choosing of the mistress.)

Let them choose and go from there . . .

Oh, not sure how you might deal with the some who while being caned would try to insist or demand you stop . . . Perhaps allow and not pay them or arrange to gag him or her before the caning . . .
