Although there is no physical contact you still need to ensure that you're holding up all ends of the bargain. So for instance where your slave needs a reward, allow it to relieve itself on camera for you. Punishment is harder since there can be no physical enforcement, however if the sub will play along with you, you can have it spank itself (again on camera) or in a more realistic way impose more of a moral punishment, such as not being allowed to speak for speaking out of turn etc.. It's a new frontier and anyone with more experience than myself I welcome your input as well as I'm sure Wolf does.
