Jeff could only stifle his laughter as Rex ran around the yard farting constantly, the smell was just awful. The poor beast was clearly in some discomfort as Rex would have to stop playing just to push out the building shitty gas building inside. Jeff could only imagine the hell he was putting his friend through, the humiliation Jay must feel as he unleashed meaty, stale farts from his new asshole mouth. How powerless he was to stop his new body from opening and clenching as more disgusting air erupted out of him spluttering causing him to make wet fart sounds. Jay must feel worthless, helpless and pathetic and that made Jeff feel powerful and horny. Jeff had to try and hide his rock hard cock as he imagined each fart from Rex's asshole was another wail and cry for help from Jay. Jeff had never felt such a rush, he had never been this dominating and cruel and he loved every second. That's why when he saw Rex pause, sniff around and start spinning he knew he had to record the disgusting act Rex was about to commit just so he could relive Jay's ultimate humiliation over and over again.
With a booming fart Rex crouched over and raised his tail, for Jay with his limited vision he could just make out the yard and a figure holding up a phone which he assumed was Jeff. Did Jeff know he was here? Was this his doing? The scared little ring of flesh didn't have time to dwell on the possible betrayal as the full feeling in the back of his throat edged closer to his lips. It was then something soft, mushy and slick hit his tongue and Jay screamed. The foul dog waste slithered over his taste buds coating them all in the disgusting, toxic, putrid waste and Jay went into sensory overload. Jay wailed and fitted in his mind trying anything to escape the hell he was going through as the smell and taste of fresh dog shit invaded his mind. The little anus would appear to be spasming to anyone watching, noone none the wiser to the torture Jay was enduring. If Jay could have cried he would have had tears streaming down his face as his new anus body stretched out painfully wide and he felt the first fat, dog turd slide out of him and pile onto the ground just inches away. Jay had the vile feeling of vomiting and gagging as he passed the never ending log of shit out of his mouth, the slow snaking of turd just amplified the humiliation. Jay was in hell. His senses were on fire and his mind was fraught with humiliation, devastation and disgust, he was supposed to be a human man, not the foul shit spewing ring of muscle stuck on the ass of his friend's gassy dog! However, Jay's reflection of his current fate only lasted for a short while as another slimy dog shit crawled up his throat, Jay was an anus and his job was to fart and shit, so that's what he needed to concentrate on. Even if he tried to think of anything else his mind would not let him. Jay had to focus, he had a job to do, he had a massive load shit to pass.
