Not sure why but I have been in a mood for stories with machines/machine type things (gyanoids, androids and so on and so forth). So here are a few ideas.
I can't let you do that...
A new spaceship is being tested in the depths of space. It is ran and powered by a new type of computer, a highly intelligent machine. During a freak cosmic storm though, something goes wrong. The machine starts to take on a life of its own and it has decided that it and the pilot will be together forever.
A twisted romance, mostly nc and maybe extreme, the computer has fallen for the pilot and proceeds to use the entire ship at its disposable to lay claim to the pilot, maybe even improve on the pilot so they can always be together.
This can be fleshed out a bit more of course.
Resistance is Futile!
More of a Star Trek game (though it can be reskinned into a different world), a starship has been attacked by the Borg (or some other machine/human species). One of the crew is still on the ship trying to find a way out. The problem is the Borg Queen has taken an interest in this individual and intends to make them its newest consort.
This game would be just as much about the chase as the torture/assimilation.
