Lydia opened her eyes and found she was looking up into the gaunt, eager, intense face of man perhaps in his early forties with close-cut greying hair and horn-rimmed glasses. Over a shirt and black tie, he wore a white lab coat.

Lydia tried to open her mouth and found a rubber-sheathed bar of some kind had been jammed between her teeth, holding her tongue down. She tried to move her arms and legs, but they were pinned down in some way. She was lying naked and tilted with her feet down at an angle of perhaps 30 degrees from horizontal on a cold metal sheet taller than she was and perforated with many holes like heavy peg boarding. Through these holes several hoops made of thick bar metal had been pushed down over her body and secured beneath it, effectively clamping her in place. One hoop formed the gag bar which had been jammed between her teeth and another pressed against her throat. Straining against them she lifted her head and saw more hoops across her middle, arms and legs, which were held straight and spread while her arms were pinned down to her sides.

She was in a room that looked at if it was situated in the attics of the Hall. Its ceiling sloped inward, and skylights let in pallid grey light. Arranged about the room were stacks of antique looking electrical equipment with big dials and heavy Bakelite knobs and switches. Behind small windows let into the panels she could see the glow of glass valves as large as light bulbs.

As Lydia squirmed and whimpered in fear, straining futilely against the immovable hoops, she felt her nipples picking up as if in acute awareness of her utter helplessness. Almost absently she noted that her breasts showed no trace of the cruel whipping Howard had inflicted upon them. The white-coated man looming over her smiled at this unwilling display and tweaked and flicked her rising nubs of flesh with evident approval.

'I see from this delightful show that you are ready for the experiment to begin,' he said. 'Not all my subjects have been as eager. I'm Alexander Durnsmore, by the way. I was always interested in science and what it can teach us about our true natures. So, I built this little laboratory. But getting suitable subjects for my experiments was never easy. There were complaints... but never mind that now. You are here, and that's all that matters. Let us proceed...'

Lydia shuddered and rolled her eyes and made desperate squeals of disagreement. What sick new game was this? The phrases "Frankenstein" and "Mad Scientist" popped into her mind not as stereotypes but full of genuine dread. In this place it seemed just as in a nightmare that anything was possible. But Alexander ignored her feeble protests. He moved to the nearest device and came back holding a pair of heavy electric cables with big sprung clips on their ends the size of cars starter cables. Lydia's eyes bulged in horror, and she tried to shake her head, but the hoop straddling her mouth did not let her.

'Mature, erect women's nipples might have been designed for this purpose,' Alexander said as he closed the metal teeth about her hard teats.

Lydia screamed and her eyes fill with tears as the teeth seemed to bite right through her throbbing nipples. Then the weight of the cables dragged down on her breasts as Alexander let go of the clamps. It was agony... but it was only the beginning.

Alexander bent over her waist, stretching heavy rubber cords that had bolted into the sides of the table over her thighs. They had triple pronged claw-like hooks on their ends which he hooked into her labia. She sobbed as they pulled her pussy lips wide, exposing the dark mouth of her vagina. As her pussy was opened wide, she felt a helpless surge of juices flow out from her cleft and dribble onto the cold metal slab to which she was clamped.

'Excellent... excellent,' Alexander said, dipping a finger into her discharge and rubbing it against his thumb. 'I will be able to achieve maximum penetration...'

He rolled out a device mounted on a heavy tripod stand with large castors for feet and which trailed more heavy cables connected to the equipment banks and positioned it in front of Lydia. The stand supported a horizontal rod a metre long with a bulbous metal tip and many ribs, studs and flanges down its length. Between them were set many glass bulbs and rods.

'This is my new model vaginal probe and stimulator,' Alexander said, patting the device proudly. 'I've already had some most remarkable results with it. I'm sure you will appreciate it its power...'

He threw a switch and the device seemed to come to life, humming and thrumming while the glass bulbs and rods flickered with light. Lydia realized its tip was lined up with her gaping and stretched sex mouth. She tried to shake her head again, squealing frantically, but only succeeded in dribbling saliva down her cheeks.

Alexander rolled the probe forward and slid its end up into her. Lydia sobbed as her lower belly bulged with its girth as its ribs and flanges rippled between her slippery sex lips, forcing her vagina painfully wide. Its glowing lights were swallowed up by her passageway, but she imagined she could feel them illuminating the interior of her birth canal.

On and on the probe slid forward, stretching and filling her. No! That was impossible. He'd burst her! But somehow, she stretched to take it inside her. She had never been filled so totally and completely. It was horrifying... and yet she felt her sheath desperately squeezing tight about the pulsating, flashing shaft.

And then Alexander stopped driving it up into her and locked the device in place. 'Maximum penetration,' he said with satisfaction. 'That is really splendid...'

He threw a switch on a panel and powered blinds slid down across grey skylights, plunging the room into darkness except for the glow of the machine's lights and dials - and a soft flickering glow which was coming from Lydia's belly!

The lights of the probe buried deep within her were not only shining out through her stretched and gaping pussy a mouth, but up though her stomach wall. She was being lit up from within!

Alexander threw another switch. The panel lights flickered, and she heard the crackle of electricity. The probe began to pump back and forwards with a hum of gears and motors, setting her glowing belly bulging and sucking in time. Then with a flicker it stabbed her insides with electric fire, making her sheath clenched about the terrible shaft in a stranglehold as if trying to squeeze the life out of it while she sobbed with pain.

There was a fresh crackle of electricity and her nipples seemed to explode as electric needles hammered through them. She bit on the rubber sheathed hoop in her mouth and screamed about it while in the darkness through her tear-filled eyes she saw sparks arcing between her clamped nipples.

And so, the probe pumped and stabbed her from within while her clamped nipples burned and stung from without. Waves of pain coursed through her while her juices, pumped out of her drooling and impossibly overstretched vagina and dribbled onto the metal plate beneath her. The most sensitive parts of her body were being subjected to intolerable stimulation. Tormented beyond the limits of her resistance, Lydia screamed and cried and sobbed and bucked convulsively while Alexander looked down upon her with his face eerily illuminated by the panel lights smiling in ghoulish delight,

'That's right, Lydia,' Alexander said encouragingly. 'Don't fight it. It's more powerful than you are. Let it fill you, let it penetrate you, let it take you over. That's what you're made for....'

How could he do this to her? How could he be so cruel? She could not take any more. It would kill her! He would...

And then something seemed to burst within Lydia like an electric shock all of her own making. Her vagina clamped so tight about the pumping probe that its motor grated unable to drive it forward or pull it back. A cloud of her expelled juices sprayed out over the exposed end of the probe, sparkling in its pulsating lights.

'Yes, we have achieved orgasm!' Alexander cried.

For a moment Lydia felt as if she was crackling and spitting with power. And then darkness claimed her.
