Kinda fell into this one through instinct and accident!
I'd decided to pet name one HB Miss Moneypenny (or Moneypenny now hahah), and the convo got here:
HB: I look forward to my next assignment Bond!

(PS: I get akick out of being called Bond - I dont make apologies for this hahaha)
Couple of hours later:
Me: It'll be an undercover assignment...

u got the skills? x
HB: Fully equipped sir! previous background in this kind of thing, any vitals I need to know about?

x (Bravo she bit)
Me: (Escalate) Close quarters, some wet work, we'll have to be in hard and fast, could get hot...

can u handle that? x
HB: Check, check, check and check, thats affirmative...i foresee no problems with this one x
Me: (Whoa skippy, de-sexual) Exshellent. You're hired! Enjoying your day? x
HB: blah blah blah what you been up to? x (fluff)
Me: (tease) Well Ive been txting this girl she's kinda awesome but I think she only wants me for sexual deviancy..and sorting out band stuff x
HB: (picks up on tease and goes with it) She sounds like a cool kinda chick! Think you should definitely follow that one up!

x (POW)
Me: (dont get too eager now, then ESCALATE) I think I might...oh we need codenames, I'm Papa Bear, yours is Deepthroat. Cool? x (RAMP THAT FILTH YOU SHIT!)
HB: Its probably for the best, covert op such as this one, cant be too careful...

x
Me: (DHV) I agree. Discreetness is my middle name, metaphorically speaking...mission details to follow

x
HB: I wait with baited breath

x (Good girl.)
(AND DISENGAGE)
This aint gonna work for every girl, but what does? - calibrate it and you are laughing.
I like it cos it gets a playful and sexual vibe going, pushes and pulls (a little bit), even allowed for the old discreet DHV to get in.
And this happened organically and naturally - so much easier when you've got a willing partner eh?
Please fell free to critique, flame or praise!
