The road trip from New Jersey back to the firehouse seemed to be dragging on forever. In the backseat of the Ecto-1, Peter's palms were beginning to sweat as they gripped the sides of his seat. Peter hadn't taken a crap in five days and had to pee on top of that. Beads of moisture stood out on his forehead as he ground his anus against the seat and struggled to keep the contents of his bowels from escaping. But it was no good. Slowly, his anus expanded and the huge, bulbous head of a giant turd started to emerge.
As it touched the back of his briefs, Peter gave up and let the massive poo slid quickly into the back of his briefs. The relief was immense and he pushed hard, forcing more and more poop out of his rectum. His briefs filled with and increasingly and impressive amount of shit. He even let go of his full bladder and pissed himself. After realizing what he had done, he hides his face in his hands in embarrassment. Especially after realizing that his friends were in the car.
The smell soon became apparent to his friends. Winston, who was sitting apart from Peter, sniffs the air and announced:
Winston: Peter, did you just shit yourself?
Peter: I just couldn't hold it in anymore.
Egon: I don't know why you did, Peter. We are only five minutes away from the firehouse. Guess you just have to get cleaned up when we get there.
Peter: Shut up, Egon.
Just getting back to the firehouse, Peter goes upstairs to get cleaned up, which takes a while, cause it was a big mess to clean up. Waiting outside the bathroom is Winston. Apparently, Peter wasn't the only one desperate for the bathroom, but at least Winston waited til he got back to the firehouse. While waiting, Winston could feel the pressure against his anus and it was extremely powerful. The wait to use the only bathroom felt like it was going by terribly slowly. He didn't want to have an accident, like peter, so he's determined to hold on.
Winston: Come one, Peter. Hurry up.
But Winston's bowels had other plans. Almost immediately, his anus opened wide and a truly enormous mass of poop began to emerge. He paused, feeling out of breath then leaned against the wall before pushing again. The widest part of the poo started to slide inexorably through his anus, which expanded three inches in diameter. With a rush, the next few inches followed, but there was still plenty to come. As his briefs were pushed away from his buttocks, about ten inches of semi-hard poo slid quickly into his briefs, curling up and nestling against his butt cheeks. This was followed by some softer poop, which oozed downward to the front of his briefs and caressing against his ball sack.
By the time Winston was done, his briefs sagged under his uniform and bulges outwards by several inches. That's when Peter exited the bathroom in a towel and instantly could smell what Winston did.
Peter: What happened, Winston? Did you shit yourself?
Winston: Not funny, Peter.
Peter: Well, bathroom is free. Might as well get yourself cleaned up.
Winston: Shut up, Peter.
Now, it was Winston's turn to finally get cleaned up.
