Still waiting... I do have some rounded tissue because I had some degree of man-boobs pre-transition, but the actual breast tissue itself is still a bit cone-shaped and only just starting to look like mature breasts, I'm still an underdeveloped B-cup 3.5 years into HRT. (But at least it's obvious that they're breasts, I guess.)
Hopefully now that the t-production factories are gone I'll finally get them to finish growing, hopefully, maybe...
