Visiting NYC this weekend, and looking for a unique S&M experience mixed with full service gfe. The VERY naught girlfriend you wish you could find ! Hoping for Friday night incall appointment. Would appreciate any help. Please email or respond with post. Appreciate the help.

To the best of my knowlege, any real pro Dom won't even consider full service.  If you are lucky, you will find one who will finish you off with a HJTC.
Your best shot will be to try a full service gal who doesn't mind some S&M as part of the fantasy.
If you don't mind a muscle gal with tatoos, Celine might do some S&M for an extra fee but don't expect anything heavy.
Good luck
