Okay - I'm probably going to get 'slammed' for this, but;
My interest isn't in 'huge breasts', per se. though, on the balance, i find larger breasts to be more, um... *exciting* then small ones, it's not my MAJOR interest.
For me, in terms of sexuality, it comes down not to the size of the breasts on a woman - but how she REACTS to have those breasts.
A woman who, for whatever reason, has large breasts but is ashamed 9or embarassed) by them will do nothing for me - while a woman with smaller breasts then that hypothetical example above, but who shows herslef to enjoy them, excites me.
That said, a woman who meets both criteria is something altogether differnt, both exciting AND arounsing - and Mistress Rhiannon is both of these things.
Though you, as the viewer, might not appreciate her particular 'look', it is more then obvious that Rhiannon ENJOYS the look she has. the costumes she wears in her photos, the expressions and poses... and, more then anything, the very fact of the photos themselves, tells you that this is a woman who enjoys herself - and it is a 'herself' that is created, rather then a simple fact of genetics or fate.
There are exactly eight women I rate as being utterly 'comfortable' with the personas that they have willingly, knowingly, and perhaps even eagerly 'created' for themselves. Mistress Rhiannon is one of these. If you look at the wide variety of very evocative 'costumes' she has, the way she is comfortable with her own body in photographs, you understand just how RARE it is for any woman to be this... well, confident. (How many women do you know in 'real life' who, as soon as a camera makes an appearance, shy away, uncomfortable with the thought of themselves being captured for posterity, no matter how much prep time they might have had prior...?)
Rhiannon, on behalf of all men everywhere who can both respect and enjoy (in SO many ways) what it takes to be a woman of your caliber - I salute you!
