Except for the uninterrupted internet access, the only thing you actually need is a computer (desktop or laptop) or a mobile device where you can watch femdom videos or participate in private sessions live. These days, every mobile device has one, and most of the computers have a webcam as a part of standard equipment, so the only thing standing between you and your latex mistress is a number of tokens remaining on your account.
Remember that watching is free on most of femdom women cams.
