I) With only the vertex selection enabled, select breast bones on one side only (unless your model's chest is asymmetrical) and click the W button on the bottom bar > Ctrl+A > click W again > Ctrl+K. (+ F7 > Get OBJ to store the selection just in case.) Remove unwanted vertices by selecting them and pressing Ctrl+H. (Once you're done, store the selection again.) If you're working on only one breast:
※ Press A to enable virtual axis, you can now orient the handle by dragging the rotation circles while holding down Alt. After making sure you've selected all vertices, orient the handle along the line from the center of the breast to the nipple. Be warned that the orientation will reset if your selection changes.
F2 > Handle Operation type: Tension Movement > move the handle by dragging the Z axis (blue cube) to just behind the backmost vertices relative to the axis. (Alternatively {only if you're working on one breast}, move it to the nipple by dragging the cubes and stretch the titty with this handle type. Switch back to Compound Move handle type and scale & move the breast vertices from the root to prevent the tits from scaling into the torso. Scale all axes by dragging the center with Alt held down. Move and reshape further until satisfied, then Morph Editor > Edit (E) > Mirror Edit (M) > any choice (if 1 breast).
