Best outcall for 3hrs+ with kink/fetishes?
 

Still pretty new to this region, so hope the bros can help me out a little.

I want to setup an outcall for 3hrs or more. I have some kinks/fetishes that necessitates outcall setup, and no it's not BDSM. Any advice on the best way to set this up?

Would a regular escort agency and briefing them ahead of time of what to expect be good enough? I don't want the girl to show up unprepared because this will not be like her usual routine.
