one day you came home from work, another boring day in your boring life. You see a strange hand bulb pump on your table. You pick it up, and a note says “pump me”

you pump it a few times and out comes purple mist, followed by a chubby purple genie. She talked in a flirty voice, as if knowing she will have fun

Ohohohoho! Hello cutie~ I’ve randomly selected you to use my magic pump~ I’m not like a normal genie sweetie… I grant unlimited wishes… granted you have the stomach capacity, ohohohoho!

when you ask what she’s talking about she puts the bulb pump up your butt

You see sweetie… I can grant you as many wishes as you want… but you have to be able to hold them all… ten pumps for a basic wish… twenty pumps for a wish that effects others… and one-thousand pumps for a world changing wish~

Any air you accidentally fart or burp out will magically regenerate in your stomach… so be sure you like having a big belly~ ohohohoho!

Oh and be sure not to pop yourself~ she smirked after she said that
