I see. I'm torn now. Kneeling with the armbinder suspended from the ceiling makes more sense from a utility and ergonomics standpoint, but my original idea was more missionary position, or a frogtie-- sitting down, supporting herself with her bound arms. Her legs being spread apart, the shins possibly bound to the thighs, her vagina bared. The idea was that both of her orifices were left vulnerable, leaving her to be used however the user pleases. I'll leave it up to you, however.
At any rate, maybe the mask has its plug dangling from a chain at its corner, her tongue left hanging out.
