It was now the Club Head's turn on the stage, and the Twins rolled out her prop of choice. She said nothing as she stood in the spotlight in her white bikini.
The device was a keg, a barrel of some sort. Wooden sides, and metal rims around each end. It was on its side on raised legs, putting the barrel at waist height. The Twins spun it around, and showed that at one end was a small hole, fit for a neck. At the other end were three, one large oval and two smaller ones to each side. In the top were two more halfway between the ends.
They then undid hidden latches and pulled ten spikes from inside the barrel, each longer than the the barrel was round, one Twin holding onto them while the other spun the barrel around again to show that there was nothing hidden on the inside.
With their assistance, the Head climbed into the barrel and rested on her back. Her head went through the small gap on one side, while she folded herself up. Her ass stuck out the other end, while her wrists rested inside the smaller gaps. Then, as they closed up the barrel around her, the Head put her legs through the upper holes, leaving her heels poking into the air.
The Twins distributed the spikes, five each. They started on the near side of the barrel, each pushing a length of spike through the side. If the Club Head was flat, this would pin her arms to her body below the shoulders, and above the wrists. Indeed, her hands flexed with the contact.
Then they stood behind the barrel, and with perfect synchronization, stabbed down through the barrel on either side of the Head's legs. These would pass through her chest and her stomach.
With the two spikes in place, the Twins pulled on them, showing that the barrel would rotate around the legs it stood on, small wheels allowing for this. They spun the woman inside around and around before stopping her on her side facing the audience.
Under her half-mask, she smiled the two women each spiked the barrel again, going through the whole thing and through her on the inside.
Then they spun her around again, and finished crossing her body in the middle, where her legs came through.
With two pairs of crosses holding her in place, the Head was spun around and around, losing one of her heels in the process before the Twins stopped.
They still had two spikes left.
Turning the whole contraption, they faced the Club Head toward their audience. Standing out of sight, they each busied themselves for a moment with her bottom before finishing what they were doing. The Head gasped.
With empty hands, they turned the Head back around to show off her bikini bottom, flush against the woman who wore it. They each gave her a quick slap on each cheek, then walked off the stage, leaving the Club Head helpless for all sorts of spinning and twisting at the hands of the winner for the evening.
