Nipple torment on the sybian until sweaty and wrecked

The two of them are locked down on the sybians, spread and straining. Dia hangs wide, feet off the floor, a bowling ball dragging on her neck. Ariel's wrapped tight in chain, bolted to her machine, nipples stretched down to the floor and hair yanked back. Both of them know what's coming. Sweat starts to roll. The vibrations don't let up, grinding against raw, swollen flesh until every pulse feels like too much. Dia's nipples are sucked fat and purple; the green castration bands snap on and bite hard. Ariel's nipples are cranked tighter, cords digging in with every twitch. The flogging lands heavy on Ariel's chest. When the orgasm rips through her, the tails snap down vicious and final, ripping the clamps off her nipples. Dia struggles for air, throat squeezed by the weight, coming again and again while the vibration drags every last shudder out of her wrecked body.
