The problem with these types of sites is that they are pretty expensive.
Most of them, including Fap Shows and Im Live have one main way of interacting with the cam models and that is by going into a private chat.
So why become a member if you can watch the live sex show for free?
Well, it’s because the more registered members there are that are willing to tip in a room, the faster the model reaches the goal and starts the show.
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.
