Chelesea is a cutie, She was a c cup when she got her string implants after which she wound up around a big f cup just right for feature dancing.(her original plan)
But strings work (grow) by the friction inside the string mass causing fliuds to build up and enlarge the pocket. The string mass then unravels and expands in this larger pocket and the process is renewed. At the time Chelsea had gotten hers she was one of the very first (kayla K was first)and no one really knew HOW big the implants could grow to. Theoretically they could grow forever... and thats the beauty of it... the "what if" factor is allways there.
At some point the growth can be stopped by visits to the dr for shunts for fliud drainage. Chelsea has elected to not do this up until recently when she hit the volume of approx 10,000cc implants right before AVN last year. She reported that at that size it was becoming very difficult to perform daily functions. She rarely dances anymore because the vigorous motion triggers a massive growth spurt.
(one gal who recieved the implants, (further down the road timewise than chelseas, who had been inspired by chelseas big boobs...) had them removed in less than a few months because, being an active dancer, they literally scared her to death with overnight 1-2 inch a day growth spurts! -she was only 5'-0" too...)

Chelsea doesnt need to do porn because she has such a BIG client base of followers she makes more than enough money.(her followers would LOVE it but she has elected not to.) She does not even escort as most people think of it. She gets 750 1/2 hr, last I heard, for you to get the privelige to come to her room and sit down and watch her dance and strip and maybe cop a few feels. its even reported you cannot remove your pants in front of her, So from what I've been told sex is completely out of the question.
She lives in Minn. and has built a very, very nice house, new cars and stuff on income from those boobs. When the time comes she will go back to a standard implant we are all guessing of 800 or so ccs. Chelsea is married and has a family (not a fact but all info points to it) so she has a support group already. all in all a very smart lady.
others with string implants are minka, kayla kleevage and the big blond maxxie.
chelsea does well in that she is cuter and younger than the avg gal who goes the big boob route (most are older gals who arelooking to hang on a bit longer to their adult careers).
If a truly cute gal got this serious and did this she'd make major bank. AND if she escorted she'd be hella rich.
its a whole nother world than porn. completly different set of rules.
