It started out when he was floating above the moon. Which was how he would tell it no matter how many times that bloody space core would yell at him about orbiting and blah blah blah blah. It's FLOATING. And he spotted an odd pink cube on the surface. And that was how he met a man named Doug. Sort would always skip most of this part because of "reasons. Science reasons. Way too complicated for a silly little human to understand."
So that's how it started. And it continued with the core asking, very politely mind, for an android body to help him get around the place. After all, this Rat person survived Her for years, surely something like that would be within his capabilities. And it was. And he made the core an android body.
And that was how it continued. The story reached its zenith when Wheatley had to get an upgrade. And then the lab rat had to link him up to a system, and that involved ports and plugs and Wheatley had never before felt or even heard of anything remotely as amazing as that experience.
And that was how it got to this, with him twiddling an audio jack between his long, slender fingers, before pressing it against the port located in his lower back, pretty damn close to his tail bone. The first time he did this he had tried arching off the chair for ages but that was a pain, and so now he was just sitting half off the edge with his legs spread. And it slid in and suddenly pleasure was quite literally jolting up his spine and slamming into his head, and his entire brain almost short circuited for a moment. And then he yanked it out and groped with shaking fingers for a computer jack, and he slid that one in a lot more slowly and then he had an entire CPU hooked up to him and he arched up off the chair with a loud groan and ruined his trousers.
When he woke up his legs were spread wide and the plug had fallen out, unplugged by his own hand falling limp. His head was laying limp, resting against the back of his chair. It was uncomfortable, to say the least.
"Man alive."
