And expand they did!
Joanna felt a brief moment of pain as her breasts were painfully compressed by now her too-small bra, before the clasps on the back gave away.
It seemed though, that she had overshot her original goal by a pretty decent margin.
She reached up to cup her left breast and bounced it in her hand a bit. These were at least D's, probably larger, but she'd have to actually measure them to be sure. Not really having had to worry about cup sizes before, Joanna was kind of lost when it came to bra sizing...
In any case, she thought as she reached her hand up to inspect her nipple, she had noticeably overshot her original goal.
Did she want to try and knock off a cup size or two, or was she happy with the new size?
