Jenny smiled as the sexy hostess invited the audience to hurt poor Felina. A committed sadist, even her "restraints" had been intended more to inflict pain than to confine - now there was no need for pretence. She stalked on her high heeled boots, knowing that by now Felina would hear the steps and know it was her tormentrix returning for more, fear making the experience all the more intense.

At first glance, the device seemed innocuous: like a joystick with a big ball on top, the weight making the joystick tilt to one side. She quickly explained to the audience, however, that the base contained a series of piezo-electric crystals, the little devices which produce powerful, painful but harmless sparks for lighting gas stoves.

"I was worried poor Lou here might get bored with nothing to do for hours while Felina tries to escape - but we need someone to hold this heavy ball in position, so that should keep her ... entertained..."

With that, she placed the device in Louise's hands and clipped a series of wires to both girls' most sensitive areas. To "help the girl focus", she rolled a tight rubber hood into place, blocking out Louise's vision; just before the hood obscured it, the audience clearly heard a quick succession of sharp crackling noises. Her expression and the way both girls jumped in pain made it obvious what had happened, but after a few seconds of struggling in agony the chained blonde managed to get the ball back into the middle position and stop the shocks ... for now. How long would it be before she slipped again, though - and would her poor muscles manage to hold the ball up for the whole six hour ordeal, even with such intense agony as an incentive?
