If you search back a ways here, you'll find this has come up a couple of times.  The most common names that come up are Tuzdae and  the Jessica that goes by "Jessicas" on Eros and "JessicaRedHot" here on TER.  Both are very erotic but also truly sweet girls, neither would ever consider trying to push whatever limits you discussed.  Also heard TymberLee throw her hat in the ring in a previous thread, but I don't think she has the gear.  Two others who's personalities seem well suited to the task (assertive, adventurous, playfully wild, etc.) would be Catherine or Misty, but have never really heard either refer to it as being an option.

Bond to the rescue, if you're prepared to wait a while....

The GFE Domme rule perfectly sums up my more wicked side.  It's a fine balance, but if done well, loads of fun and intensely erotic for both parties.

BTW, your fantasy isn't as 'off the wall' as you think.  It's interesting, but I've found that the more authority and power a man asserts in his day to day business life, the more willing and eager he is to relinquish control during playtime.  It seems to be part of the pysche that makes them successful.  So maybe it's a portent of bigger things to come in your business career
