A lanky research volunteer is tape gagged, then tied spread as part of a bizarre experiment. Covered with sweat, her tender tits and snatch are clothes pinned, then her hard nips are clamped for good measure. Thus tied, she is given electro stim to her pussy and nipples while she moans with pleasure and pain.
