Jay was desperately begging Jeff to stop. But there was nothing he could do. From far back behind him, Jay could hear Rex snarfing down dozens of treats. He was frantically trying to do anything in his power to get Jeff to stop, but alas, he was utterly helpless. Hearing Jeff refer to him as nothing but a smelly dog butt hurt, but the fact that it was true caused extreme humiliation for the poor anus. The constant wagging of Rex's tail was such a pain. Knowing that the dog was happily enjoying himself unaware of the hell he was forcing on the former human was awful. Thankfully it aired out the stench of the farts a bit, but even then it was horrifically smelly.
Eventually, Rex ran along and found a nice spot in the yard to lay down. As Jay was pulled along, he could see Jeff cruelly smiling at him. After about 30 minutes of lazily laying about and occasionally letting out a small poot from Jay, a deep rumble could be heard from within Rex's gut. Jay had been around the first time Rex had eaten these treats, and it was by far one of the worst smells he'd ever had the displeasure of experiencing. The fact that he had just been fed dozens of treats combined with the 300% increase to his senses had Jay in absolute desperation. An immense pressure built up behind the anus. Jay wanted nothing more than to hold it back, but his "lips" were involuntarily forced open for the rancid stench of an upset dog stomach's flatulence. Imagine the worst smell you've ever experienced. That smell doesn't even come close to what Jay was now surrounded by. Jay was weeping from the stench of the fart. He couldn't believe Jeff had done this to him. He wanted to be human again! He couldn't be stuck as a dog asshole forever! But that wasn't a decision he was able to make now. As he cried from the sickening stench of gaseous dog waste, he stretched open again, and again, and again. Fart after fart ripped through the helpless butthole's mouth. No amount of willpower, no amount of begging, no amount of crying had any influence over his predicament. No control was given to an anus, as it was a mere part of another creature's body. Nearly 15 minutes of constant farting continued on until a momentary break was granted to Jay. Was he done? Was he going to finally stop being forcefully used to expel farts? Suddenly, a much more intense pressure built up behind him. He didn't want to believe it, but he knew what it was. Dog shit. As Rex stood up and began sniffing about, Jay was mentally screaming for someone to set him free...
