Wallace felt the serums kick in and he jumped and sqirmed in the air.
The Coachman excused two of his helpers and went to work injecting the Chicago student. "There boys all done, the D.N.A. reformation formula invented by our own apothecary Henry J. Whifflepaffer. Oh Henry understands the laws of nature so very well. He makes for me the most perfect liquids and tells me which ones are special for just the correct subject."
Wallace mumbles as the pain begins and makes him shake all over.
"Let me tell you what to expect, BROTHERS! Half laughing he continues, I am the chief Coachman here at the zoo! I am given the power to decide who gets to join the zoo as employees or like you two property."
Walking in a crazy eight circle around the two strung up boys he smiles at them with an evil grin. "Both of you should feel a burning in the chest and a gurgling in your guts. This is normal, the organs such as lungs and heart are exanding to work extra hard in the years to come. The gut is being rearranged to accept a simple diet of rough grains and of course hay!"
Phil looks at Sammy at the words of the Coachman. The two continue to hide since no rescue is possible at present.
"A tickle in the skin announces the sprouting of a black coat of thick hair. This will cover your entire body! Neat that the skin need not change to black mule hide in color, but it will thicken and toughen as your body changes."
"MUULE, MULE, exclaimed the student from the state of Illinois!"
"That's right boy, M-U-L-E a fourlegged animal used for it's strong back, big hoofs, and docile since it's always casterated. The two happy brothers of racial brotherhoed will be ture brothers, as mules!"
The secret out the Coachman walked out of the barn proper and left the two boy to change and scream.
Phil and Sammy looked on not knowing what to do. "Sammy I would save them from the changes if I knew how, but even the big man said, they were injected and that's final."
"But Wallace, said Sammy!" The wild scream of Wallace brought the Coachman back into the barn.
Ducking down Phil watched as Sammy slumped to the barn floor.
"OK, that's OK scream out your fears and with it your human mind and will. Giving in to the fear brings on the animal instincts. Those lusty instincts and a little sexual humping will leave me two fine obedient male mules, so scream on, said the Coachman."
Phil watched, and began to remember Lydia as she too gained a hairy look. Wallace's ears grew long and furred as the Coachman cranked him higher so his soon hoofs would not touch the ground.
Wallace tried to control his screaming in the hope of keeping his human memories. He blubbered and whined as his form grew and became mule. As his head lost all human form he began to bray rather than scream. Hee Hawwing seemed to quell his pain and fears but he felt him humanity slipping away.
Wallace looked at the student of unknown name, he wanted to console him but all he could say was pure mule sounds.
"Compassion for your brother, how nice, said the Coachman. In just a month he will try to kill you over the chance to mount some jennie or mare. Even without testicles a male mule feels the instinctive need to mate once he sticks his nose into a mare's rump."
The sensual thought gave a strange feel as Wallace's new hardy mule cock fell out of it's black leathery sheath. Stiffer it got as the thought of animal sex drive grew. Soon the twenty inch long member waved in the air stiff and aching for a release that would never come.
A signal from the Coachman and the winch was lowered. Wallace slowly put his much increased weight on four animal legs. A halter and bit was quickly put over the massive head and into the mule's jaw.
"Four and a half hours now since injected and I have a fine yearling male mule. Hmmm a little fattening and you should be ready for thirty years of hard mule labor, then off to the meat company, Ha Ha Ha!"
What was left of Wallace the young man was not even affraid of thirty years as a mule. Wallace gave from his best and took a long lusty pee on the barn floor.
"Take him to stall twenty four and put the other mule in the petting zoo, said the big Coachman."
"Hey boss we got some photo's from security on that white guy running around with the black kid, yelled a Coachman."
"How's the nerd taking his medicine in watch bay ten, asked the boss Coachman?"
"At first he was scared to death but after he humped his first sow the fear left and he is more than willing to be our first Tamworth boar, said the younger Coachman."
"Hmm you let him hump a sow before complete change to a boar, that's not too good Bobby. The kid will keep his ability to speak and think as a human. I want only dumb beasts, no memories, got it or Bobby might change from employee to property, said the big boss man."
Soon Phil and Sammy were alone in the dark smelly barn. "What a day, thought Phil as he saw Sammy begin to cry."
Phil spotted a light from a small office on the far side to the barn. "Lets check in there, Sammy!" The two ran as fast as the fear would let them across to the office.
A computer screen was still on and the program open with the name Bobby at the top right corner. Phil sat down and poked at the keys. "Here let me do it said Sammy, as he plopped down and worked quickly into the program.
