She stroked the shaft of the dildo, running her fingers in between the knobbles and spikes covering the shaft right up to the top, where a tapered steel spike glittered coldly.
"Women have died on this?" she asked him.
He nodded solemnly.
"Willingly?"
"Of course." He smiled.
"But why?"
"Who knows? Somehow they just seem to want it. It's almost like they have to know how far, how deep they can let it go. Maybe they want to die. Maybe they don't mean to...maybe they just keep fucking away until they die..."
"How many?"
"Not many," he shrugged, "three of mine. Five for Jim...he does this too."
"How do you get women to do it though?" she frowned.
"We show them the dildo. They want to try it and then...well they just don't stop."
"How do you do it," she asked, her breath faster now, nipples hardening perceptibly under her flimsy top.
"We grease it up really well, position it for her and, well, she just does the rest. Some girls like to get on their hands and knees, push back. Others like to slowly lower themselves from above. It's a bit personal I guess."
"This would never fit in me..." he laughed at that.
"It would. It always does."
"But...but how?" she asked doubtfully.
A good question really since the dildo was a good two inches wide and the spikes made it another inch wider again. And there was a foot and a half of steel and rubber before the support at the bottom. Surely no woman could fuck herself all the way down to the rubber seat?
"Well, the spike at the top pierces the cervix first and then the womb...it lets the shaft through into your abdominal cavity..."
He saw her shiver at the thought, running her hands over her bare midriff, eyes fixed on the gleaming spike.
"And then you just fuck it and it tears its way through whatever gets in its way. The spike at the top makes a hole and then the shaft just shreds its way through you."
She closed her eyes and moaned softly.
"Do you want to try it?" he asked.
Her eyes flew open.
"Of course not!" she snapped, "I just..."
"Of course, you don't have to fuck it all the way," he said quickly, "we could lube it up, let you fuck it just a little. The spikes don't do any real damage, just the one at the top. The others are just used to...supplement the main spike...but only when you let it rip you," he added hastily.
He could see she was thinking about it and he knew how aroused she was. It always happened this way. They would just try it a little and then...somehow they could never seem to stop.
"Ok," she whispered and he grinned. He had her now.
"Strip for me baby," he whispered and she did, slowly, grinding her body for him. Her breasts, full and firm jiggled as she pulled her top over her head. She was so perfect, a wonderful hourglass figure, perky breasts and a tight ass. Her belly was a gentle female curve, her pubic hair no more than a small stripe down the front. She waited for him, watched while he came and stood before her, cupping her breasts, massaging her nipples. She sighed gently, relaxing into his arms, kissing him deeply.
"Are you going to fuck me?" she whispered.
"No baby...I just want to watch. We can fuck afterwards."
She nodded then and stood, waiting while he got the special cream, rubbed it all up and down the shaft, coating the spikes evenly...the more lubricant the longer she would last because even if his little bitch didn't know it, he did. There was no way she was getting off that dildo once she got on.
"How do you want to take it?" he asked.
"Leave it upright," she replied, "I want to watch myself while I do it...so I don't go down to far."
He laughed, "You'll know when it gets to the dangerous point. You'll feel the tip prick you way up inside. But this is the best way I think."
He stepped back then, touched her briefly between her legs to measure her arousal...completely dripping... and then he sat back down and waited. It wasn't long. She approached the dildo and then spread her legs, the point just brushing the hairs at the entrance to her twat. She rubbed her aching slit, back and forth, back and forth for a few moments. At last her fingers parted the pink flesh and she began to lower herself, letting the steel disappear slowly inside. Steve knew that he wouldn't see that steel again until he lifted her corpse back off the monster cock.

She groaned in pleasure as she came to the widest part of the dildo and started to fuck slowly. She closed her eyes, one hand on her left nipple, the other busy between her legs. He saw her legs spread a little more and knew what was happening. The semi hard spikes and nobbles on the shaft were massaging deep into her most tender places. She was rapidly forgetting that dangerous spike at the top...her pleasure was rising and that was all she cared about. Her hips began to roll and she slid down a little further. There was about eight inches in her now and he knew that the tip of the spike was getting close...there...the little slut gasped, eyes wide as she felt it against her cervix. There was confusion and pain in her eyes that belied the struggle going on inside. She wanted...needed more, but that would mean serious pain, maybe even death. But there was an itching in her cunt now, a burning need and she knew that she wasn't going to stop, even before she made a conscious decision to keep going, she knew what was going to happen.
She yelped as the steel spike slid deep into her womb and her breath accelerated, she was panting like a bitch in heat now, eyes wide, hips rolling faster. A thin trickle of blood slid down the shaft, but she took no notice. Another four or five inches slid into her and then the spike was at the other side of her womb, the wider part of the dildo at the base of the spike was now at her ruined cervix. Again there was a moment of hesitation and he took the chance to tell her what was happening.
"You've punctured your cervix now and in a moment the wider part of the dildo will enter your womb. As you fuck the smaller spikes down the side will start to shred your meat, turning your womb into mince. Just a little more and that thing will be in your guts. You could stop now...a hospital could save your life..."
She nodded, her face a mask of concentration. She let her body weight come down on the dildo and she fell a couple of inches. Tears poured down her cheeks. It was well and truly inside her now.
She began to fuck now, working her way down the shaft slowly, rising and falling a little at a time. Inside the shaft of the dildo had turned her vagina to mince meat, but she still had a clitoris and she rubbed it madly. The lower she fucked, the hotter she got. She could feel the shaft all the way up inside her now, pressing up oddly against her stomach. Her eyes were closed and her head back, legs spread wide, feet planted far apart. With a little gasp she stopped fucking and let herself slide the last two inches down to the seat. She opened her eyes then and stared at him, grinding her clit against the seat, hands sliding over her tight stomach, rubbing at the shaft deep inside.
"What...what now?"
He stood and came to her, looking down into her sweet pain-filled eyes, a rich chocolate brown in a pale, pale face.
"Well...you're going to die. That's a fact. I mean even if you could live you've got no womb...no cunt...nothing. But you're not going to die for a while yet. So we just make sure you're strapped in," he said, cuffing her ankles to the floor, "and then you can put on a show for me."
"A show?"
"Uh huh. Here, let me show you."
He wheeled out a trolley with a device on it and parked it behind her. He pulled wires over her shoulders, wires with big needles on the end. 
"These go here," he said, pushing them through her nipples and making her scream.
"This goes here," he said producing a small clip with a wire attached and snapping it onto her clitoris and producing more screams as her world went red.
"And finally...."
She couldn't see what he was doing but she knew as soon as she felt the coldness at the entrance to her ass what was going to happen. She cried out as he rammed the steel plug home, bucking on the dildo as much as she could.
"Oh God...Oh Master...why?" she begged, her eyes filling with tears.
He sat down in front of her again and admired her. She was beautiful like this, tortured, dying, all for him.
"Because you chose to die, slut, not me. You fucked that thing knowing the consequences and I figure it may as well be worth it for me too. You do want to go out pleasing me don't you?"
She stared down at her pierced nipples, the blood pooling beneath her, the realisation coming to her.
"Yes...I do want to please you. Fry me, Master."

And then the room went white as electric pain flooded through her nipples, clit, ass and cunt. Her body went wild, heaving in pain, rising and falling as far as the chains would let her, fucking the cock inside her. She felt the pain rise and knew that her Master was gradually increasing the shocks, snuffing her slowly. Her body sweated, her cunt bled and slowly, slowly, her flesh began to cook. She thought she was crazy when she smelt the wonderful smell of roasting meat, but knew that the truth was that it was her flesh cooking. She was exhausted and aching all over, a deep ache in her muscles as well as the sharp stabbing pain of the electricity. She wanted it to stop but she knew there was only one way...and she was edging closer to it every second.

Her breasts were on fire now. She felt one final orgasm blast through her and then, to her horror, she felt the clip fall from her clit...she no longer had a clit, it had been burned away. She stared at Steve, gurgling softly and saw him smile and then with one final jolt the darkness closed in and she was gone.
