Preparing the summoning for Drenvynia for the fourth time, I was thinking, how to exact my revenge on the succubus who ruthlessly killed my parents so many years ago. She was going to suffer. Suffer big time!
I had thought a lot about whether I would want to lift the part of the spell, that kept her forgetting, what I did to her, every time, when she returned to her plane of existence. But I had dropped the idea. I wouldn’t make the same mistake as my father and underestimate her – it had cost him his life and made him kill my mother on Drenvynia’s Order in the process.
I cast the spell to call her and jumped her as soon as she materialized on the floor. As usual I cuffed her with wrist- and ankle-straps. I put the ball gag in her mouth to keep her from insulting me continuously.
Then I took her to the prepared construction for today’s session. I had used some pipes, roughly the diameter of a fist to build a strange contraption: two vertical pipes went from floor to ceiling and were securely fixed in place. At about table height a similar pipe went horizontally to connect the vertical pipes, making it look like a huge ‘H’.
At the ceiling I had prepared the hook that could be lowered by motor. On the hook I had prepared the spreader bar.
I stood her in front of the vertical pipes and lowered the spreader bar above her head. Clicking the wrist-straps to both sides of the bar, I made her put her hands above her head and used the motor to rise her to the ceiling. She was hanging on her hands moving up. As soon as her ass had passed the horizontal pipe, I lowered her again a bit to make her sit on the pipe. I stood in front of her and shoved her knees towards the pipe, to the point where the pipe connected with her back of the knees. She gasped, fearing to fall off the pipe, but her hands strapped to the spreader bar, held her in place.
I used two ropes to bind her knees to the pipe and prevent her from moving forth and back. Now I had to make sure, she stayed upright. By bending her back and sagging her shoulders she would have been able to significantly change her position.
On the wall in front of her, there was a horizontal handle. This one came handy: I got another spreader bar as weight and knotted two thinner ropes to the bar, threading them up behind the handle and towards Drenvynia. Standing there I pulled the spreader bar about halfway up and knotted the ropes to the ring-piercings at her nipples. She cried in agony, but this measure made her put her back perfectly nice and upright as the ropes pulled her piercings forward towards the wall.
Now I brought the masterpiece from the next room: I had built a vertical fucking machine. If was essentially build like most of these machines, but it had two independent tool holders and I had taken extra care to optimize their lifting height. I had prepared several ‘tools’ featuring different dildoes in wicked sizes.
When she saw the thing, I could see her eyes widening.
I placed the machine below her and put a spiked dildo on the rear tool holder.
It was similar to the one we had used on her ass the day before, but it was different by a little tube that went from below through the whole dildo and ended in a little hole on top of it. It would allow to apply lubing liquids with a syringe without taking the thing out.
To the front I placed a long metal dildo with estim-cables on it.
I lubed both dildoes a bit.
I adjusted both tool holders to place the dildos firmly into her; the spiked one into her ass, the other into her pussy. Both were placed to work in opposite directions (one in, while the other would go out and vice versa). The lifting height was nearly 10 inches, so I had to burrow the currently ‘in’ dildo – the metal one so deep in her, that her eyes watered in the process.
The other dildo was placed with its tip just inside her ass to make sure, it couldn’t slip out.
She had watched my work with an air of fascinated panic.
“Now I’m ready. I told you on the first day, that my spell would keep you here 4 hours at a time. As this will be an endurance test, it could be possible, that we’ll need this time today.”
Connecting the e-stim controller to the front dildo and putting another line to the fucking machine, I explained: “I want to see, how good you are, when it comes to *not* coming. You’ll be constantly fucked by both dildos and are not to come. Below the front dildo there’s a humidity sensor, that will trigger the e-stim controller at 3 impulses on maximum strength for the dildo in your vagina. I can’t recommend getting too wet today.
I flicked a switch, slowly starting the front dildo. It moved out of her right to about an inch from completely leaving her pussy. Then it rose again, pushing up, until one thought it would show on her belly any second. She squirmed with the last inch. Satisfied with the outcome, I increased the speed to about 2 seconds per in/out-cycle and with that to a nice fucking speed.
“Remember: don’t get too wet, or you’ll trigger the e-stim!”, I explained.
“Now to the second one: this one will kick in at the same speed as the first, just in opposite direction. As it’s spiked, it might sting a bit when it starts directly at full speed.”, I said, switching it on.
When the front dildo was all the way up, the back one kicked in – being shoved up her ass with 10inches per second. Hearing her squealing, I nearly had mercy with her.
I could see, that she was trying to get her body higher, despite the fact, that this put even more strain on her tortured nipples by pulling even more on the ropes.
Eventually she settled.
I sat down on the chair I had prepared to admire my work.
The pleasure/pain ratio was extraordinary: the spiked dildo up her ass working at that speed was even crazier as on the day before, when the assistant had gotten in revenge-mode. It created a rosebud on each way down and must have hurt like hell. The front dildo on the other side was glossy with wetness, betraying her not being able to suppress her lust. This would become interesting.
I watched the steady flow of secondly moving dildoes up and down and followed one drip of liquid making its way down the shaft of the front dildo slowly. But it didn’t happen as expected: after about 5 minutes, she cramped with an orgasm, nearly ripping off her stretched nipples in the process. A flow of cum sloshed down the dildos shaft and onto the humidity sensor.
Electricity is noiseless – but it didn’t matter: I could see the three strikes issued by the controller from her head to her toes. She screamed in agony – the ball gag didn’t help a bit – then sagging in relief, just to scream again a second later – and again.
She had had level 7 of the e-Stim before and nearly fainted – this was level 10. I could only guess what that did to her body. Nonetheless the two dildos pushed merciless into her.
“You merely took 5 minutes to orgasm. I’m not really sure, what will happen, once we reach somewhere near to the four hours, we have.”
Her face was a distorted mask of terror despite her unearthly beauty, when she realized, that I planned to keep her on this thing for four hours.
“I don’t dare to put lube to the front dildo, as this could trigger the sensor even faster. But if you want, I can do so with the rear one.”, I said. She nodded thankfully. I went over to the table an fetched a syringe full of a red liquid.
She squinted to me when she noticed the color and produced an audible “noooo” through the gag, shaking her head viciously. I picked up the little tube attached to the rear dildo and put the syringe to the end of it. Pressing its whole content up, when the dildo was at its top position, I managed to splatter the content all the way up her ass – from bottom to the top position of the dildo. Nothing happened. She relaxed.
After a minute, her eyes widened and she nearly bit the ball gag in half. Tears were running down her cheeks, her eyes a red mess. “Chili sauce has kind of a delayed trigger”, I thought.
Then it happened: she squirted violently, sloshing liquid all other the sensor. Which in turn triggered the e-stim. Three short contractions, combined with screams on top of her lungs, and again oozing cum out of her pussy.
THIS was the mother of a vicious circle! It took her five consecutive orgasms to digest the aftermath of the squirting.
I had taken my seat and enjoyed the show.
Four hours can pass very quickly – or incredibly painful – it’s all a question of the side you’re looking from.
In the end, she had taken at least five squirts and an uncounted number of orgasms. I didn’t free her, before she dissolved into thin air – she had paid in full, so she was to enjoy the full ride.
