I'm a California dude type and super excited to do the Mayo Challenge! My bro is filming me and I brag about how great I am, and how I'm going to totally win this hot new challenge and get so many clicks and likes! I start scooping the mayonnaise into my mouth, grossed out at first but playing it off, and soon finish the whole thing. I pat my swollen belly, I'm the best, dude! I did it! I'm gonna be famous! But soon my stomach starts aching and I proclaim, I'm gonna siht my pants! So I pull down my skinny jeans and expose my bubble butt, and a stream of white liquid comes out frcefully. I moan with pain and relief as I release myself everywhere. I notice my bro is still filming and I desperately try to make him stop, but he won't! I can't stop shting out the mayo though, so much is streaming out of my butthole! What are you doing bro!? He tells me that for sure I will go viral with this followup to the Mayo Challenge and my attitude changes, I'm all about the streaming mayo coming out of my butthole, and I ham it up for the camera. I ask for a closeup of my cream-streaming asshole, as the last of my challenge escapes my hole.
