I'll try one more time... any providers in DMV that will snowball?

If she will allow CIM she will usually snowball if you ask her before it's too late.

If its first session ask after you have had other types of carnal knowledge.

Don't ask her by email or phone.

As far as DF kissing you after, that will be YMMV and depending on how well you swallowed.

Those kind of questions don't usually receive a large public response.

P.S. Civilian Girls crave that sort of thing.
  It's fine to ask them at the bar when you first meet.
