There was a girl that used to come here that had a underlying diagnosis of gestational macromastia, going from an A cup to a DD. Though her husband hated her larger breasts, would refer to them in disparaging ways, and wanted her to get a reduction, she loved having larger breasts and wished they were bigger. She started studying possible cause / effects and came up with ideas of how to recreate her body chemistry changes that happened during pregnancy. When we started corresponding, she had already attained a H cup while adjusting particular supplement intake and over the following two years, she started increasing her dosages and was filing an O cup. Part of her routine included using a pump to milk herself every 4 hours while at her home computer job. She kept this all hidden from her husband, making excuses, but I could tell that she seemed to be having nearly a nervous breakdown between the arguments and her disappointment regarding what I thought were kind of unrealistic expectations of growth; expecting 4 cups sizes over 8 months, devastated at only gaining 3. She was absolutely set on recreating the gigantomastia she saw had read about and her extensive knowledge showed her obsession; she didn't want to stop until her breast weight challenged her ambulation. She took pride in having the largest breasts of all the women she knew in her town.
It all came to an end (as far as I know) when her husband discovered this site and her vast array of PMs; we had Pm at least once a day for a couple years. Also on her computer were links to numerous breast sites. The last I heard from her was from a email site she used to share photos of progress, saying that though she hated giving up, her marriage was more important than going bigger. I agreed, it was.
