A Goonimal had a run in with some grease which had a mind of its own. He heard its call... he could smell it on the wind. He could see it leaking from the trucks that were sitting for months on the site during a strike. He went to check on some things and...

He wasn't expecting this to happen... this one didn't even know this part of him was there until he had an urge so powerful that he couldn't resist trying what his body was begging him to do. He had a thought so vile to him that he needed to do it. The seemingly permanent slick grease all over him. Ever hair matted to skin slicked down by something no dude should every want That much of on his body.

He only took a little but it was enough to possess him. All grease exists to do is lube stuff up. Its only driving force is to slime up everything that moves so when a manimal grabs a glob of thick warm sludge and it tells him to spread it fucking everywhere on his naked body, he struggles to stay human. As he drives from place to place so none of the civilized humans see what he's turned into, clothes feel unnatural and clean skin is beginning to make him cringe.

He feels like one of those snails that has been taken over by those parasitic warms that live in its eyes and control its brain... He feels used for the first time in his life. He feels like a slave--like this is all that matters now. This feeling defines him. The grease has soaked in and is going to stay.
