Man, I have been avoiding this thread because I just couldn't narrow it down to just two chicks, and Zinista scared me with his precision, so I did not even want to attempt that.
What I have boiled it down to is a nice sandwiching between...
Christina Aguilera (as a brunette)
and
Alley Bagget
If they were regular people then definitely this one co-worker of mine (looks like a Playboy model) and either of the two above.
