Fart Humiliation For Giantess' Stepbrother

Description: My tiny brother knows he can't touch my stuff. but while i was training he opened my protein! he thought he would grow if he ate it... stupid tiny boy! now i have to punish him. i could swallow it with the protein, but that would be too boring. my ass smells really bad after training. that would be a great punishment for him! now he will smell my ass and my farts!
