Like lolchair said, Foxy doesn't like her OF stuff posted here or anywhere.
Having the biggest boobs is indeed a lofty goal. I really don't get the "I want to be the biggest" attitude when your boobie greed is saying "I want bigger boobs;" it's really not the same because the latter expresses no specific goal, only bigger. Don't get me wrong, I totally applaud Foxy following her boobie greed and if that takes her to the point where her volume/size makes her the biggest, that would be great too, but ultimately, she has to be happy with the size/weight of her boobs, not just tolerate them to claim some unofficial title. You have to love yourself.
I have never really gotten into the 'who's the biggest' debate as it is more observational, thus subjective. To me, it is all about following your inner desire, your boobie greed, which isn't about numbers, it is about self-satisfaction, that point where you are happy about how huge your boobs are. It is probably somewhat of a balancing act between how big you would like to be and at what point the weight stops being fun; yes, I believe the weight can be a fun factor with boobie greed because you actually like the way your boob weight pulls, presses, and effects body movements. Recently, Foxy responded to a OF member and equated her getting in and out of bed as being like a turtle on its back, which is something I have alluded to in other conversations as likely being the case. Unable to just sit up without using her arms to push herself into a sitting position, she probably uses her arms to scoot her butt to and from the side of the bed. I hypothesized that boob size and width makes crawling or rolling into bed more difficult and at Foxy's current boob size/width, I would suggest she already cannot really lay on her side fully, but is angled a bit towards her back. If or when she gets to Beshine's size, I imagine she will have similar results; her sideboob will not allow more than a 45° thus one boob always pointing skyward as the other lies on the bed. But the key point remains happiness, you have to love all the ways your boobs make your life no longer normal and embrace those things, feel good moments if you will.
