I never understood some girl's assertions that their "falsies" felt like a
part of themselves. I felt at times they contributed to my sense of being a
fraud. The only reason I used them was to be able to present a more feminine
form. The first ones I used, were made of knee-high stockings filled,
to the desired size, with rinsed and dried birdseed.
I found because of the weight, it was difficult to keep my "breasts"
in the cups of my bra, which resulted in a few potentially embarrassing situations.
I solved this problem by putting each falsie inside a knee-high and tied the ends together.
I wore them with the knot behind my back, weaving the "breasts around
the band of my bra and into the cups. I knick-named them my bolo- boobs.

The next ones I owned were "previously owned" silicone forms
that I bought from a friend. Of course they were lighter, less hassle
and more comfortable but, still at times, I felt like a fraud having to use them.
After I started HRT and my "Girls" developed to their present feminine beauty,
I am comfortable enough that I only need the little extra shaping provided by
a pair of silicone enhancers. I am not a fraud, I am a woman.
