5) Add another loop which will help us form the armpit later. The loops will go all the way across the back

6) Remove the offending edge to preserve our nice quad mesh

7) Nipples! Create the outline by bevelling the verts

8) Breasts in 3 easy steps!

1) cut in more edges from the existing points and keep the nipple outline circular.

2) create and move enough edgeloops to define their shape. Some people might want to add lots of edgeloops here :)
Remember gravity and let them droop a bit. Also make sure they angle out with the center about where the spine is

3) extrude the nipples from the nipple outline.

9) Extrude the existing faces into arms

10) Delete the end polys and add a loop for more shape. Make sure the new loop doesn't cross the armpit but flows behind it. The highlighted face should be exactly where the armpit goes
