"God dammit." Sam thought to himself, "it's probably one of those stupid jokes trying to play a prank on me."
Sam throw the bag down and turned on the TV. Sighing, Sam was getting board since there was nothing on TV. Looking to his side, Sam saw the bag and decide, "what the hell. If it is a prank at least I would have some excitement."
Opening the bag, he noticed that the first cracker he saw
that there was a person cracker. He pulled it out and putting it aside. "Yah like would eat that"
Going back to the TV he grabbed a cracker from the bag and taking a quick bite.
"Oh no, I am going to change into some animal!" Sam thought amusingly. As soon as he swallowed the piece and was going to get another bite. When he noticed that his pants felt a little tight. At the same time he was getting this strange feeling all over his ass.
"That's weird these are my baggy pants." That's when he heard a loud rip and the tightness went away.
He got up quickly and looked at where he was sitting. His pants and underwear where tattered all over the chair. He looked down and saw what he usually saw. But different. He noticed his hips where wider. He looked behind him. and the blood ran from his face.
His ass was completely different. It was huge and had brown fur on it. And even worse he had a tail. A long horse's tail.
He looked at the cracker in his hand and he could make it out as a horse with a bite taken out on it's ass. "This can't be happening.. It's impossible." he thought.
"Maybe it's coincidence" he thought as he looked at the cracker. "Why don't I try bitting the hooves."
He raised the cracker and bit off the back hooves. As he was chewing the hooves his feet started to feel numb. He looked down to see his toes turn black and start to mold into hooves.
Sam dropped the cracker and ran toward the person cracker and tripped. He wasn't use to the hooves and the extra weight of his new ass. He crawled to the cracker and ate it all.
As he finished the cracker he heard something hit the bag. He didn't care at all. He just stared at his ass and feet hopping that they would change back.
Slowly his as started to shrink. So was his tail. His feet were getting feeling in them as the hooves separated and formed back to his toes. He got up and felt his ass and feet, making sure that they were back to normal.
As he was checking he noticed the horse cracker on the floor, was as if he didn't take a bite out of it at all. He picked it up and dropped it back in the bag. When he did, he noticed that the one human cracker was also back in the bag.
Sam was so confused on what just happened. After thinking for a while and putting some pants on he decided on that he could try a different cracker to see what it would be like. But which one, he wasn't sure one.
