Massage the entire breast with your hands and gently draw circles on it, sometimes fast and sometimes slow, using both lips and tongue and changing techniques frequently to bring about multiple climaxes. Among a woman's erogenous zones, only the breasts and sexual organs are considered the highest sensitivity areas. A more accurate statement would be that it's not so much the breasts, but rather the nipples. Some people, when stimulated, can reach orgasm even without penetration, as long as the nipples are caressed.
