In the quiet hours of one rainy night, a young scientist had decided to spend her time in a dark make-shift lab she had set up for herself at her home. From the lack of noise coming from her flat, you might think anyone home was fast asleep at such a late hour, but you'd be mistaken, because Eliza was screaming in pleasure in her sound-proofed lab.
In fact, Eliza had strapped herself into a machine of her own construction, and was now writhing in her bonds as her most prized possession masterfully brought her to orgasm after orgasm, using a combination of all the tools at its disposal. Mechanical hands were massaging her breasts and pinching her nipples, while powerful vibrators buzzed away as they were pressed onto her clit and stuffed inside her in just the right places.
It had all started months ago. Eliza completed a research project investigating the possible uses of a new design of robotic hand that was completely indistinguishable from human hands. She looked into many ways such a development could help the world, but as the project came to a close, she decided to start a side project of a more inappropriate nature. Eliza saw the sexual potential of a couple of mechanical hands being able to intricately follow any instructions while feeling exactly like a human's hands, so she wasted no time in getting to work creating an initial prototype for what would later be her greatest masterpiece. This project would have to remain a secret from her co-workers, so she decided to carry it out at her home lab.
Eliza was quickly able to build two mechanical hands to use for her personal project. She created a small machine to attach the hands to, and began coding their function - for now, she just wanted her tits fondled. It was easy to get them to massage her breasts just the way she wanted - she simply recorded herself squeezing and groping her naked tits, and computer vision did the rest. Of course, the very first prototype was unsurprisingly not great, as the hands seemed to randomly move around her chest area without pressing in any of the right places. But over the next few days, Eliza recorded herself massaging her breasts every chance she could, and the hands quickly learned the best techniques for pleasuring her in this way.
Eliza immediately began using the machine every time she wanted to pleasure herself - it was addictive. She would bring the machine to her bed and place it next to her as she lied down. The robotic hands would squeeze and play with her tits while she had both hands free to finger herself while holding a vibrator against her sensitive clit, bringing herself to a screaming orgasm.
But why stop there? Eliza decided to continue her project beyond just two hands massaging her breasts - she needed to think bigger. If she could build a bigger version of this machine, she would be able to attach several more hands to it, and perhaps a whole range of other tools as well. For the next few days, Eliza fantasised about surrendering herself to her robotic creation, with its hands exploring her whole body and vibrators automatically being applied to her private regions.
Eliza spent the next month building the contraption of her dreams. She built a comfortable platform that she could lie down on while being explored by the mechanical hands that would extend from the machine onto her exposed body. Once the setup worked with the two hands on her tits from before, she began expanding her collection of tools. The first thing Eliza wanted to add was a vibrator that would automatically extend to her pussy - she wanted the machine to make her cum without her doing anything.
Eliza didn't expect this task to be too difficult. She had already built several cameras into her machine to guide the tools to the right places on her body, so she programmed the vibrator to be extended out and pressed onto her pussy. However, she soon discovered that making this completely hands-free was going to be harder than she thought. Ideally, the vibrator would start off at a low setting and build up as she got closer to the edge, but right now she had to do this manually, as it was too complex a task to program the vibrator to make her cum.
