Is this girl actually suspended by her twat? Powerful pussy! Guys you don't want to stick anything in there, when she came she'd squeeze you down to the size of a toothpick!
I'd say at least the weight of her head is being carried by the two upper struts that attach to the collar she's wearing and the weight of her arms is being born at her wrists so the pressure on her twat is not as extreme as it seems at first glance.
