Matt saw the android option and found himself drawn to it. He'd had vague fantasies about being a robot before and now he had the option to actually become one it was really quite tempting. He'd still technically be an object, but could still retain his humanoid form so he wouldn't lose all control. And looking at all the options available to him it looked like he could significantly improve himself in the process.
Matt scrolled through the various options, taking as much time as he could with his hard-on throbbing painfully, demanding that he go through with the change already. He made sure that his mind would survive the transformation unchanged, but that he'd have a powerful processor to improve his intelligence and thought processes. Going through his specifications he made sure that his new body would have wi-fi. No way he was going without internet, the thought of having it pumped straight into his mind was heavenly. Next he gave himself upgraded senses- eyes with a powerful zoom and hearing that he could adjust at will.
Moving onto his physical appearance Matt decided that he wanted to look roughly as he was right now. Though of course that didn't mean he couldn't make improvements, he thought as he sculpted his android shell to meet his desires. He decided to keep his own face but renovate his body, removing any imperfections and buffing himself up so he'd appear to have a swimmer's build. He'd finally have the hot body he wanted, even if it would be a plastic one.
He decided that he would be made of plastic, after idly pondering what it'd be like to be a solid gold android, but used the Chronivac's power to make his material shape particularly exotic. Normally he'd be a hard plastic, so he'd look like an unusually realistic mannequin, but if he wanted to he could make the plastic more soft and flexible, if done all over he'd end up looking more like a love doll. He liked the idea of having more control of his form like that and thought he'd look pretty hot in both forms, though he noted to his annoyance that shifting forms apparently used a lot of power.
Being the pervert that he was, Matt paid particular attention to the sexual features of his android form. Naturally he upped the sensitivity of his touch sensors, particularly around his genitals and orifices, so he could get the maximum pleasure out of his time as an android. Then he got to designing his genitals, making his cock and balls look like an incredibly realistic dildo that had any number of vibrate settings he could play with. He then moved onto his mouth and asshole, making sure that they had maximum flexibility that he could control at will, as well as giving them self-lubrication and vacuum functions so he could really have fun with anyone who wanted to fuck him.
He noticed that all of these additions would require a lot of power, and as he didn't fancy shoving a nuclear reactor inside himself he'd need some way to charge himself. He decided to create a charger that would function as a stand, with a pole sticking up from it that would plug into his anal cavity and power him up that way. Might as well have some fun with the tedious process of charging after all. As a little extra he decided to create a remote control for himself, which someone else would be able to use to control him if they got hold of it. Part of him thought he was being a bit reckless with that but the dominant horny section of his mind had visions of the hot sex games he could have with that, letting someone control his body would be like the ultimate bondage.
He fiddled with the reality settings so that people would remember him as a human in the past, but also wouldn't find anything odd about his conversion into an android. He figured that'd be the option with the least hassle. He also made the transformation permanent- if this went well being a robot would be so much better than human life, and if not he figured he could just use the Chronivac to change himself again. Finally, he hastily stripped out of his clothes, not wanting them to be messed up by the transformation, skipped through the various disclaimers without really reading them and hit transform.
He immediately felt his body stiffen up, he couldn't move a single muscle. Then a harsh buzzing sound started ringing in his ears, then overtook his mind until he blanked out. He wasn't fully conscious but was in some sort of dream state, his mind was vaguely aware of lines of code flashing through it. He felt vaguely queasy as he was aware of his insides shifting, and he thought he felt a lot more heavy than he used to be. Then nothing.
