You seldomly get this much projection from anybody else. 
The nature of Allegra's breasts to project more than become round has always made me wonder about her expanders. While they always appear round by designed volume, hers have not and I can only cite Beshine as another example of expanders and still not having anywhere close to round, even at 10k. Of course, at 20k, they are finally looking much more round. So I wonder what size Allegra's expanders are; maybe 3k?
