You've seen them sitting at their keyboards, wearing barely anything, winking at you, typing to nobody in particular with thin, lethargic arms: bored and conventionally beautiful.
The ads, with flirty video that might be live or recorded years ago, shout at you with promises of "Live Sex Chat" and "Sex Shows", with both amateurs and "pornstars" alike.
It's a web red light district, and unlike some gaudy Dutch strip or seedy sidewalk, you're completely anonymous. The basic premise of the cam girl game is a simple one: You pay a girl for her time, and in exchange, she'll take off her clothes, talk to you, play with herself (and others), or any combination thereof.
When your money is up, so's your time — the two of you part ways until you've got the cash and willingness to go at it again.
To find them, look no further than the Big Three of cam girl delight: Streamate, Live Jasmine and My Free Cams.
These three mega-networks advertise across the mainstream porn tube sites of masturbating ubiquity — Porn Hub, Clip Hunter, etc — but are shells and shadows themselves. The requirements are meagre: a computer and internet connection.
