"Prepare to join your friends!" says the man is into Ken's other arm goes a seringe filled to full whith a brown liquid.
Handing the seringe to one of the other men he looks at the label and then draws a questioning face.
Smiling at his friend the first man says, "His friends are verile male donkeys for making mules, right? Well he gets to work right next to them except he's going to be a male mule already!"
Still questioning his partner the man's question is on his lips when he is informed of Ken's special place.
"He's to be a teaser!" says the man.
"Teaser?" comes the questioning reply.
"When a mare in heat is placed ready for one of those Jackass boys to fuck her pregnant she might injure the young male. So when made ready she is placed with a "Teaser" animal. A male but not able to make her pregnant he can fuck all he wants but has no balls for mating! If the mare turns violent he takes the beating rather than the stud donkey. Then it's his problem to stand and long for her his erection out steel hard but no way to accomplish his delight. Understand now?" says the man.
Ken is standing there quite as the other two men look at him showing wonder.
"Why look at me so? At least I'll be near my friends if not helping them stay healthy. I must say though I'd of made you a proud and willing stallion had the offer not turned depraved!" says ken as he rubs his hand over the last injection point.
"Enough, begin his treatments and call me when the serums begin to show major effects!" demands the one man as he walks out of the room.
Now things get active as the one man moves the still trussed up nanny woman to one side. She tries to kick her hanging hide hooves at him but when she can't her head hangs down in udder viewing.
Now its Ken's turn to be trussed up off his feet. Once hanging helpless in the air the men put on red chemical suits as they start a compressor working. Ken can only watch as one man steadies Ken by holding on to his bare feet. The other man stands with something like a spray gun made for painting automobiles. It begins as the spray comes out in a dark cloud.
"Easy there buddy in don't hurt but the coating adds pigment to the skin making you quite black of color. Once we add one of the special toughening formulas your skin changes to be as thick Mule hide ready for extreme hair growth. Just hang in there and you'll be well on your way to a Mules form and life within a few days!" announced one of the men as Ken closed his eyes for the spray.
The spray is warm and Ken finds himself becoming very relaxed. So relaxed he soon drifts off into a slumber of willingness to be changed.
The sound of voices as the men talk awakes Ken from his slumbering.
Slowly heavy eyelids open and Ken seeing the men discovers his first degraded sense, sight. Now the men look like they are on an old Tv as shades of gray replaced the colored world Ken was used to seeing.
His second feeling was even more strange as with having discovered his changed sight he became nervous. A sign of any nervous equine is the flicking of a tail. Ken tried to look backwards over his now hairy shoulder to see the tail he knew and felt was there.
Seeing their victim now awake the managing man walks up to face Ken looking up he smiles. "I see you are finding the first few feelings of Muledom to be quite different from being human! Trust me it only gets more interesting from this point on." says the man to Ken.
