Thinking of a good idea, Ty turns and shoves his rear right on Dustin's face and catching him by surprise. He then lets out a long, wet fart, causing his brother to gasp and cough."HAHA! How do you like that, you fucking piece of shit?"
"M-more!" Dustin moans, being very turned on by the action. Ty was almost caught aback by the unexpected reaction, guessing that the pink mist bring up all fetishes and kinks into someone. Shrugging, the god-teen starts pissing on the other's chest, giving Dustin a nice piss bath as urine splashes on every part of his body. The piss-covered teen opens his mouth and Ty happily obliges him, sending a stream of piss on the foster-brother's tongue and mouth. Once Ty was done pissing, he felt his bowels move and really needed relief himself.
"Get under my ass, Dustin!" Ty orders the sex-crazed boy, watching him get off the chair and lay down between Ty's legs and under his ass. He squats down halfway to hover his ass-cheeks just a foot above Dustin's face, grunting as a nice, wet log slides out. "Rrrrrrg eat up, you toilet!"
The shit log breaks off halfway and lands perfectly in Dustin's mouth, prompting him to moan and chew on it. The other half lands on his face, getting into his eyes causing Dustin to wince in pain and irritation. Ty grunts and groans again before unleashing a flood of diarrhea to cover the older teen all over the chest and stomach area.
"Yess...Yess I love being filthy.." Dustin starts rubbing the feces all over his body, releasing his bowels as well to shit on himself. The younger teen unleashes another spurt of scat on Dustin before stepping away. "So goooood...so amazing..I..I love..being shit.."
Ty wishes for himself to be entirely clean of any feces, taking some time to look around Dustin's room like he never done before. The poop-covered teen was in a pile of shit and urine now, almost something like heaven to him at this point. However, Dustin did not realize he was slowly becoming part of the shit pile he was in. His arms and legs became more sludgy looking, following his lower body and chest. Right before his head became part of the same thing, Dustin had enough muscle strength to let off a happy grin, becoming part of the inanimate pile of feces and filth.
Ty laughs once the transformation was finished, deciding it was time to leave the house and see how his new and corrupt world is doing.
