Unaware giantess stepsis protein farts - OnlyVanessa

Description: Ok so i’ve been building a bunch of muscle lately, which is all fun and games until you’re farting like crazy. i try to hold them in, but whenever i’m at home i just relax and let them all out. except today what i wasn’t expecting was that my weird stepbrother would shrink himself only to end up trapped underneath my huge ass while i fart all of it out. so stinky and disgusting. the more protein shake i drink, the worse it gets, i fart and burp like i can’t stop while he takes all of it in…    i bet he’s enjoying it though. weirdo.
