Blackmail

Being an Ultimate can be unlucky because almost everyone has a reason to blackmail them. If not for perverted reasons, then for their fame or skill.

If an Ultimate Programmer is blackmailed, they could make the best website or video game and the blackmailer could sell it and let the money roll in. They could even make money through them in more perverted ways. Like, having an Ultimate do a fund raising live stream and promise to get naked if they reach $100k donated and within the hour, the goal will have been reached.

Of course in those cases, it's usually a stranger trying to blackmail them... But sometimes, it can even be another Ultimate. One blackmailing the other purely for erotic reasons. To have a breast to grope every day on the way to class, or a mouth to suck them off when they wake up.

For Ultimates, especially female ones, they have to be really careful about being blackmailed...
