It depends on the definition of "huge boob women"or "xxl". I agree that these are great times for people who love around 2000cc. So many amateurs are going for this size now, and it looks like its getting more accepted in general.

I've noticed the lack of women who go 8000cc+ for quite some time, and i think I might know the reason. In short its difficult. The cost are really high, requiring multiple surgeries for most women, and ongoing medical care during the expansion. When a woman wants to go for 8k+, there is no other route than to go for custom made implants, and they cost a lot. I've talked to numerous women who wanted to go for this, and they all had to stop because they ran out of money.
And talking about customs, good luck finding them. From what I heard, the really big customs take a lot of work to find. First you need to find a company open to producing them. After that they need to be convinced to produce custom xxl sized implants.
Even if they manage to get the money and the customs, they need to be able to actually handle it. After following most of the current xxl women it's clear genetics are a huge factor. So far only a tiny group of women has been able to go xxl easily without skin problems. The majority simple can't handle it. Their skin becomes tighter and tighter, and it stays tight. This is why you see most women max out at around the same size.

So far only Beshine managed to get the funding, the custom implants and actually handle this level of expansion. An amazing achievement thats often underestimated. I think in time we will see another woman exceed her size, but It will require us to be very patient.
