This is hot but it could be hotter.
You have a piss kink and really love scat.
“I wish she pissed and shit constantly. And that she found it hot”
The genie snaps their fingers and you girlfriend/principals stomach gurgles. She rushes over to a toilet as she pisses and shits loudly, it turns her on so much that she starts fingering herself.
“I wish that I had the power to make it stop and start any time I snap my fingers”
You watch her for hours as she shits and piss, you even make out with her as she does
