It was over. Zacus removed his cock from poor Caius’s body. He started to calm down thinking his ordeal was finally over.
It WAS over right? Or was it?... all of a sudden he felt a tremendous pain centered on his lower body. He started to feel strange.
He cried for the slave to give more of the potent yet relaxing aroma. But at the same time he realized that the slave was gone, he suspected the aroma was what was causing this new pain.
“Now you are mine! My partner forever!” proclaimed Zacus. As he said this, Caius felt a strange sensation overcoming him; it felt as though his entire body was experiencing a huge growth spurt.
He could feel his muscles pulsate, as they were growing. He could also feel something like fur growing over his lower body, and a feeling that it was getting larger. At that exact moment he realized that whatever was in that jar…was turning him into a centaur. He screamed in pain as his lower body began to show equine characteristics. looking down he could see as his thick penis and heavy ball sack swiftly turned black and began to quiver and change shape, his heavy ball's shrinking and pulling up. Even as his thick prick seemed to shrivel, getting shorter and shorter, The pink slit of his urethra was widening and lengthening before moving further back to under his new tail. "Oh god...oh god what's happening???" Caius stammered as he watched in terror, as his male hood twisted and warped; into the shiny black shape of a female Horse's sex! his terror was only heightened when he felt a tingling and swelling sensation in his chest. he watched on in horror as his once manly pecs began to balloon outward to form nice firm shapely Female breasts. As far as his lower body went, the long, slender body of a mare was finally revealed. The same slaves that put him up on the platform, then came back started to release him as the change was almost completed. Zacus smiled as the young man, soon to be centauress, dropped to the floor, too tired from pain to get up. After what felt like an eternity, Caius’s transformation was complete. A slender, less muscled body with large firm round shapeley breasts, which looked nothing like his original body, rested atop of a sleek, slender mare’s body. He could feel a strange heat and wetness in between his hind legs and under the tail of his new centaur body. Stunned, at the changes he started to get up when suddenly he began to feel extremely hot. he moaned as Zacus stuck a finger into his tight wet heat. Zacus smiled "perfect. My broodmare is now ready to be bred"
