Thank you so much for the reply’s. I have already purchased flange adapters and I am currently using 17mm. I am trying my best to pump twice a day for 20 minutes at a time. The feeling is unlike anything else and I can definitely see how it might become quite addictive. After completing a session I as well believe my breasts feel heavier and full. Were you actually able to achieve a DD cup size just by pumping or were you using any other supplements? I’m also curious as to how long you pump for roughly?
