Ty and Dustin decided to skip their last class and headed home.
"Want to do some experimenting?" asked Ty as they walked through the door.
"What do you have in mind?"
"We each write down different things on paper and we each take turns pulling one out and changing the other into that form for 5 minutes." Explained Ty.
Dustin replied, "Okay, but how are we going to do this when you are the only one who can change things?"
Ty responded with, "I think I can make it so that you will be able to change me as long as I let you."
"Lets do it!"
The boys spent the next 15 minutes coming up with about 50 different changes that could be made.
Dustin broke the silence "I can't think of any more, can we start now?"
Ty replied with "Sure can, who picks first?"
"Why don't you" responded Dustin.
Ty reached into the pile and pulled out a folded piece of paper. Opening it up Ty read it and smiled. It was one of his choices and thought it would be a great start. Ty pictured a donkey in his head and started the change.
Dustin sat waiting for the changes to begin wondering what he would become when he started itching all over the place. Dustin watched as the hair on his legs slowly became thicker. Lifting up his shirt he watched the new hair grow up his chest and completely cover it. Dustin thought he was just becoming rather hairy (one of the changes which he had written down) but a sudden weird feeling in his ears changed his mind. He reached to touch his ears and found that they didn't end where they should. After following his ears for what seemed like forever he found the ends sticking up about a foot out of his head.
Dustin ran into the bathroom to confirm what he was feeling and there in his reflection he saw his new jackass ears. He was distracted from his ears when his clothes started to feel tight.
"Come back in here so I can watch!" Ty yelled down the hall, "Oh, and you might want to take off your clothes or it might get rather uncomfortable."
Dustin headed back into the living room and had already removed his small shirt. The fur had almost covered his whole chest and back. When the button on his shorts burst free he removed them so they wouldn't rip. As he pulled them over his feet he saw that they had elongated quite a ways and that his toes were starting to form hooves. Dustin heard a rip from behind as his new tail began to extend from his spine. Ty giggled as he watched Dustin's tail free itself from his now tight underwear. Dustin's waist continued to expand and was about to take them off when he saw what was happening with his manhood. He watched as his dick slowly began to grow and make its way out of the top of his underwear, what he saw looked nothing like it looked before, it was covered in a furry sheath that completely hid his new equipment but still managed to make it halfway up his stomach. Dustin quickly began to remove his underwear as his balls grew in painfully large. His ass was now covered in a thick hide and from the waist down he almost looked exactly like a donkey.
"This feels so weird." Dustin said in a deepening voice.
Dustin's hands began to clench and harden into front hooves. His neck began to lengthen while his face started to protrude outward into a muzzle.
As he fell onto all fours Dustin tried to speak again but all that came out was a loud "HeeeHaaawww"
Ty opened the back door to let Dustin out so he could explore his new body. Before long, five minutes had passed and Dustin began to change back into himself.
Now it was Ty's turn to be changed.
