Look you could potentially fit ANY size bra with the right modification and you have TWO of the exact same mod, and your .... are SMALL enough. I have the benefit there I must say. Never though being a size B would come in so USEFUL. I could go all Dolly Parton with a padded bra and shove a legend in EACH.
Disadvantages: possible back issues, you'd need to approximate the same size so that means ALWAYS carrying them, or having other "fake boob" bras to compensate, what happens if someone sees you
vaping it, metal detectors would be a REAL problem and a sudden medical exam being sprung on you might raise some QUESTIONS.
But, it's entirely doable and I THINK if someone wants to, they should. This is my OTHER Joan of Arc for "vaping today" if you think you could PULL OFF that trick YOU SHOULD. IF you want to, JUST DON'T SMOKE.
I can also think of other places anyone could put a mod (with more discomfort though) but I'm NOT spending all my Joan of Arc moments at once.
LOL just don't let the FDA win.
