IMO, CB, you may have a very different idea of what Sammy is that what's really there. You almost describe her as a guy with big tits, with very limited emotional requirements and a straightforward manner. Her behavior paints a completely different picture. She's acting like a total girl. As far as I can tell, she seems to put up a really good front to her friends, but you've strayed into the "here be dragons" territory. You can't expect her to still be the super casual girl she was before you got near her beardless clam.
