Nobody

After looking across the dating website and finding nobody who you really wanted to mess with, you decide to switch up your angle. You were thinking with your dick since the moment you got this power, but realized that you could use it for far more than just sexual pleasure. In order to conduct experiments on how your wishes work, you decide you need a somewhat 'safe' environment for testing, and what safer environment than the internet.

You think for a moment, wondering what activity would be the most fruitful. You've never been the most creative person, but this is the internet, you don't need to have your own ideas. You open reddit, and pop over to r/askreddit to see if you can gain some insight. You make a post and within moments receive several replies. Scrolling dully through all the joke replies. 'My dad back.' 'A chair'. 'More wishes.' You finally find something useful. 'Make people start being nice to me.' Not exactly what you were looking for, but you could work with that.

"I wish everybody was nice to me" you think, and then it is so. Of course you aren't satisfied with just that, so you add "I wish any person I talk to would become even nicer to me every time I say the word 'please'" and then that too becomes reality. Devious thoughts slink into your mind as you think about what exactly you could get away with due to these wishes.
