Jeb returned to Livery Stable and Stella. As He walked in Stella was holding the long rein on Ken. Much to Jeb's surprise he saw Ken the sexy male mule deeply enjoying a mare tied in one of the stalls.
"Daughter, what in Hell's name are you doing? He's still very potent his semen count will be fifty times that of a stud, while he now has a stallion's volume."
"But Daddy he's so pretty and so well endowed. Why just standing here he curled his upper lip a snuffed toward the school teacher's mare. Well that mare started winking her rump at him at he was not to be denied."
"Daughter, he has not been trained for such, besides Doc Fenton is coming back soon and I need time for this new remede to work."
Jeb and Stella tried to move the mule back, but Ken was enjoying his twenty inch long cock as the mare was young and tight. The cream given to jeb was in his shirt pocket and in the scuffle it dropped to the stable floor.
Finally Ken's stamina was played out and he backed off the pretty mare. Covered in equine sweat and mule cock hanging around Ken walked in circles, trying to calm down and wishing for a cold shower.
As best Ken could muster he BRAYED alound and pawed the ground.
"But Daddy, I think he still wants to mount another mare!"
"Yes, Daughter he does. Once at stud the animal lust is coupled with sexual pleasure. Then the human thought process increases the desire by realization of how much pleasure he felt. It's a madd cycle that once a volunteer starts, keeps him or her an animal for life."
"So even though I branded him as an animal, you now have started his male instincts to procreate." Seeing he was way over Stella's head in terms jeb summed it up. "Stella due to your feeling sorry for him he now is a stallion, a stud, and a mule, all of which Doc Fenton is planning to change."
"Ken my good volunteer, said Jed as the stud mule turned and BRAYED. I have a cream here that if I rub it on your sheath and testicles will save you from the Doc."
"But Daddy, said Stella, picking up the bag of cream. It' says here that he would change sex and then he'd be female!"
Ken, began to Bray, Bray, Bray..................!
