I believe things really started evolving once Live Jasmin made its entrance.
It wasn’t much of a cam site at the beginning, but somehow they managed to raise the bar during the years and developed, at least from our point of view, one of the best live sex sites out there, maybe the best.
Sure, free chat is available with almost all these sites, but that’s mainly to attest that the cam girl you’re watching is really the one you’re looking for.
Most webcam girls will not really sustain a conversation during the free chat and will certainly not reveal any kind of nudity.
Of course, they were limited by the technology available at that time.
