It would be more normal to install the masking tape, run a thin bead of
latex painter's caulk down the edge, and wipe in tight with your finger

The automotive and marine industry uses a tape that is more plastic than your
typical masking tapeand gives a much finer edge.  If you ask for fineline tape
at an autobody supply store you'll get the right stuff.  Then it's a question
of burnishing down the tape edge with a rag.  I've never used fineline tape on
a wall before so it might have too much adhesion - do a test.

A couple of observations/comments:  I'm guessing you mean the blue tape when
you say masking tape - you don't want to use regular masking tape because it
sucks big time.  The blue tape costs more but is well worth it.  Also, the best
edge you can get is by just cutting in with the angled sash brush.  There's no
need to get overly fussy with the paint line - you're not painting a 1/8" pin
stripe on a car...your eye will never see a tiny discrepancy buried in a corner
eight or ten feet up.  Practice cutting in.  It's much faster and you'll pick
up all sorts of speed when you're doing windows and such.  One trick is to
breath out and hold your breath just before you start the cutting in brush
stroke.  It helps steady the hand and your body.
