Double Inverted Sybian Suspension

Cherry and Ariel hang by their ankles. The rig stretches them, exposes them. Two sybians press hard between their legs, motors humming, pressing right into their cunts. The girls take the weight of the machines and the pull on their ankles, but the power of those vibes keeps them twitching, moaning. Every grind against those saddles sends another jolt through them. The first orgasm hits fast, legs shaking, mouths open. Then another. And another. Sweat runs down their bodies. Their muscles burn, but neither girl taps out. They ride it out. One more climax. Then another. The motors keep them locked in place, pulsing, grinding, forcing more out of them. Tension builds in every strained muscle, every forced moan. They take it, both of them, until their bodies go limp and the vibrations still pound between their thighs.
