The attendants watched in fascination, and Jenny in horror, as the large stallion’s features began to recede.
His skeleton and muscles quickly shifted around with a series of loud creaking and cracking sounds. The horse’s elegant black and white fur steadily gave way to pink human flesh, whilst his tail and mane began to withdraw. The hooves on his hands and feet also started to loosen up as they began to separate into fingers and toes.
However, Jenny was most distressed when the concoction began to affect her mate’s genitalia. Prince grimaced in a strange mix of pain, pleasure and release as his still-erect penis began to shudder. He then moaned loudly as he sent long thick ropes of cum spurting against the stall wall and floor as his enormous testicles emptied themselves dramatically.
The mare was horrified to see all of that valuable seed go to waste. Surely, just a few drops of his potent semen would have quelled the heat inside her, whilst also making her an expecting mother. Now she listened in anguish as what seemed like gallons of the precious load were unleashed; sounding like a garden hose spraying a wall.
As Prince continued to cum powerfully his balls began to shrink as they started to run dry. This was accompanied by other changes. Prince’s body mass had lowered dramatically causing his balance to change. His enormous head had also become less pointed as it increasingly resembled a human face. The emergence of two fleshy growths on Prince’s chest signalled his change of gender as a curvy pair of breasts took shape.

Then he would finally be free of this accursed, heat-ridden mare’s body.
Jenkins got more and more excited as he saw that his antidote was working like a charm. Soon, where Prince once stood, the stablewoman lay naked on the stall floor; clearly exhausted from her ordeal.
Two attendants quickly wrapped the woman in blankets before they helped her stagger away. Jenkins desperately hoped that she was all right. Now she was his only chance of returning back to normal.
Jenny was led away to her stall where she nervously waited to see if the antidote had been a success.
She ended up waiting until early the next morning when it turned out that…
