Of course she can. It is scriptural...ideal that ones cups runneth over.
However as a female I can attest to the fact that smaller is better. Far more comfortable, simpler to attire and not prone to heat rash underneath. Who wants big melons bopping around...plus as one ages skin loses elasticity and those knockers can end up in your armpits or kicking around your hip bones. Seriously gentlemen....wound you want nine inchers dangling between your thighs?
So....Sister Wannaman can have her augmentation scripturally, but it would behoove her to rethink the wisdom of her decision.
And Sister Wedtodumdub can as well...providing she has her husbandly owners permission.
