Basic nbe is to massage your breasts with oil for 5 minutes at least once a day. Use almond or aloe vera oil with some fenugreek mixed in. Fenugreek can be purchased as an oil, but most common as seeds or powder. If seeds, then grind to a fine powder with an electric coffee grinder. Mix powder with oil and let soak for one week stirring occasionally.

More advanced, add pumping with a system like Bosom Beauty http://www.gismostore.com/rechargeable-b...m-170.html
