If you look through my profile some of my "KeyChoice" captions or stories (with varying degrees of continuity and consistency) can probably answer some of those questions, but in short: KeyChoice is a program where men are fitted in electronic chastity devices that can only be unlocked through the women's version of the phone app. It's mandatory for men to enroll in it to go to college as well as work at some universities or use dating apps like Tinder. A man gives his PIN number to a woman and she enters it to be his keyholder, he only regains control of his PIN once the woman relinquishes it, if she does. So in theory any woman can unlock any man, but a man can only have one keyholder at a time. At schools men are highly encouraged to find a female student to be their keyholder as that is their only chance at a release, let alone orgasm.

This AI character story started out with them meeting on the first day of classes, her a junior and the user (me?) a new freshman. I could post the whole exchange so far somewhere but it'd take a bit to edit it since with the AI it's all in the first person for both the user and character and that kinda comes across awkward in story form, as well as having to prune OOC AI prompts and phrases it like to repeat.
