Two weeks had gone by for Cindy and she had tried the original chair several times, coming over and over again as the big dildo had slid wetly into her. Only now, she wasn’t sore for days afterward as her petite body had adjusted to its size. Indeed, on her last trip, the machine had finally dropped her another two inches down the shaft, stopping with a full 12 inches buried in her tight twat.

Cindy returned to her room to find the phone flashing a message light – when she answered it, she received a computerized message telling her she was scheduled for the exam room tomorrow and the day after. She had never had an “appointment” before, but she was getting used to the surprises around here and forgot to mention it to her sister.

The next day, Cindy showed up at the appointed time and found the room empty – she had thought someone would be there to help her, but once she thought about it, she realized that the equipment was all automatic and didn’t need any help once it was started. She stripped naked and put one hand in a stirrup and watched as the machine adjusted itself for her size, then she climbed up and sat down on the bench. Reaching over to the sides she opened the panels and removed the “breast enlargers” as she thought of them, placing one on each breast. They immediately slid down the sides of her breasts as her nipples popped into the ends of the suction hoses, the sensation started her lubricating heavily even before she could get settled in.

Cindy then placed the waist strap over herself and put her arms and legs into the stirrups. As soon as she put both hands in the stirrups, they snapped shut on her wrists and the padded part pumped up with air. The strap held her firmly down in the middle. The foot stirrups were two-piece and only the bottom half had cuffed her ankles, the other half of the stirrups slowly moving up her legs until they were just above her knees. Once there, the cuffs inflated snugly and as Cindy watched, the bottom half of the table began to spread her legs while the cuffs at her knees and ankles were forcing her legs up and spread. She wound up laying on her back with her feet almost flat, knees wide apart. As she stretched, she felt her pussy open up; she couldn’t help herself, she started to produce lubricant immediately.
Once she stopped moving, she heard another sound and saw a mechanical arm rising up from underneath the table between the split sections – on the end of the arm was a very long dildo, but this one wasn’t slim like the first time, this one was thick.

It was producing lubricant and slowly rotating as if it was on the end of a drill. As it contacted her pussy lips it started to stretch her wide open, and then just started to slowly push her up the table until the foot restraints stopped her from going any further – the pressure slowly mounted until, with a wet pop, the head popped into her pussy. Pressure sensors in the head of the dildo sensed the vise-like grip Cindy’s pussy had around it and the dildo stopped its forward motion, slowly rotating around and around as lubricant came out of it. After a few minutes of this, Cindy realized the pain was going away – it was starting to feel really good. As she relaxed, the pressure on the head of the dildo decreased and it slowly started burrowing into her narrow fuck tube, forcing it open as it buried itself into her, an inch, two, three, six. It stopped at six inches and began to reverse itself. It repeated this action, screwing itself into the horny girl to the six-inch mark and then unscrewing itself until it came out.

It kept on repeating until, finally, Cindy couldn’t take anymore and came, hard. As her orgasm swept over her, her cunt squeezed down on the shaft, closing a set of contacts. Now the dildo started getting a ¼ inch deeper with every stroke, she came again and the motor whined a bit more. The suction had increased on her nipples as well – they were now almost an inch long and her breasts also felt larger. She was now coming almost constantly as the machine just kept getting deeper into her. The machine finally got ten inches into her and stopped moving, buried to the hilt in her pussy. The dildo started to slowly rotate again, very slowly as the split part above Cindy’s legs started raising itself up, moving Cindy’s pelvis up and tipping the cervix inside so that it would be lined up with Cindy’s vaginal canal. Cindy couldn’t see it, but the end of the dildo had shrunk down some, but it was still a lot fatter than it had been the last time the machine had fucked her.

The very tip of the dildo touched Cindy’s cervix and penetrated it a ¼ inch. Even with the lubrication, it was painful. The dildo stopped with the tip of itself just inside of Cindy’s cervix – it started to vibrate and Cindy came again. Pressure sensors in the dildo detected less pressure from the cervical opening and the dildo unscrewed its length from Cindy’s dripping twat. Cindy breathed a sigh of relief just as the dildo came out of her, only to squeal when the dildo started to screw itself back into her dripping fuck hole, not stopping its slow advance until it had planted ½ an inch through Cindy’s cervix – it vibrated, she came. Cervical pressure dropped and the dildo repeated the process, this time planting itself into Cindy ¾ of an inch into her cervix. On the next stroke, Cindy felt the tip of the dildo go through her cervix and into her uterus. She screamed and came again. The dildo just kept up its slow advance into Cindy ¼ inch at a time, Cindy was moaning and having frequent orgasms as the machine kept pressing in further each time.

Cindy heard the little bell chime and remembered that it meant, “Twelve inches, you should run out of pussy in another inch or two.” Her sister had said. Cindy just moaned and came again, then again as the machine plowed 13 inches into her.

At 13 ½ inches the machine hit the back wall of Cindy’s womb. Sensors detected the contact and the dildo withdrew ½ an inch, leaving 13 inches buried in Cindy. The bell chimed again and a digital readout showed 13 ½ inches. At this point a small powerful pump proceeded to fill Cindy’s womb and uterus with a very warm liquid. Cindy felt it and screamed into her final orgasm, fainting dead away. The machine filled Cindy up until it reached a calculated pressure and then stopped, leaving the incredibly potent mixture of sperm it had just filled Cindy with, completely soaking the egg that the ovulating Cindy had dropped into her uterus that day. Even as Cindy was lying there passed out, she conceived.

When Cindy came to, she was laying on the table just like a normal exam, except she was slightly tipped up with her feet just a little higher than her head. For a moment, again, Cindy thought she had dreamed the whole thing, and then she looked down and realized that while her arms and legs were free, she still had the belt on and she still had the breast cones on. That and she was sore again between her legs.
