Live Privates is a fantastic cam service with a large number of gorgeous models ready to provide you with plenty of hardcore action. You can go camera-to-camera with any of the models on this website and start jerking off with them all. This is really entertaining if you go to the lesbians or couples section and jerk off with a couple of lesbians to form a virtual trio. It's clearly not as good as the actual thing, but it's a lot more entertaining and participatory than porn.
Live Privates features more models than any other site I've visited, giving you a wide range of options. The prices are also very reasonable.
My first piece of advice is to leave the chat and look for another performer if a model tries to drag you along by asking you to spend more time (and money) on her cam show without giving you much in return. There are far too many models on this website to waste your money on timewasters.
