Lara is correct less pressure for a longer time is better and use a good lotion cover your breasts with it and then pump. I know from experience to much pressure really does not increase size and to much pressure can give you water blisters --believe me my boobs were covered in blisters and took a long time to heal and painful. I use an automotive brake hand pump with a pressure gage and 5 lbs seems. to be my sweet spot I can do long periods and get good swelling. Try. to pump rice a day fro 1 hour --Happy pumping
