When you decide to go private with a model anything goes as long as she's into it.
With such an influx of sites it becomes hard to tell which ones are legitimate and the model pool becomes somewhat crowded.
Members can enjoy unlimited free previews with any one of the girls but for the most beautiful women on the Japanese cams their chat room may be full of other guys vying for her attention.
The best way to get the lovely alone is to enter into a private room and get some personal time with your favorite model.
If a strip tease is what you desire then that's in play as well.
Most girls even have a variety of sex toys at their disposal, just waiting for you to tell them where to put it and when.
