And what an opening it was! The djinn smiled at what the businessman had gasped.
"I wish I was more of a stallion!"
Even tough the djinn knew perfectly well that the businessman had meant sexual prowess only, the occasion was much too good to pass. Misinterpreting wishes was the djinn's favourite aspect of his job and nature. He loved being a mischievous djinn. Mortals were so easy to trick and put in humiliating situations! The same wishes, the same desires, the same assumption that they knew what they wanted and the same jumping to words they thought were crystal clear. It never changed across the centuries or places. So the djinn, with delight, a quite mean delight, let the magic flow and watched the extremely entertaining results certain to follow.
In the bed, Alex suddenly felt a sudden strange warm sensation. One that had nothing to do with sex. He stopped, startled, and his partner asked him what was wrong. She then started to scream and thrash as she noticed dark hair spreading upon his face and body. She swore and asked what the fuck was going on, kicking Alex to disengage and jumping from the bed. She grabbed her clothes and belongings and she fled screaming. Alex couldn't even answer her for he did not know himself what was happening to him. His mouth with big huge teeth wasn't made for human speech or screams anymore. He just uttered whinnies as he contemplated in horror his members elongate, his neck lengthen and his toes and fingers becoming one. His hair receded into a thin line and others sprouted from his lower back. The only thing that brought him some tiny solace were his testicles and penis augmenting more than substantially.
The room now held a tall, handsome and strong stallion, formerly Alex. Alex looked around, trying to make sense of what had just happened. He was completely lost as to what he was. An equine, from his hooves, but what sort? And what would he do without opposable thumbs. The djinn then appeared, explaining what had occurred and Alex's unwitting wish, uttered without him realizing it even was one. The djinn then said he could not grant the wishes of animals, not that Alex could speak anymore at any rate, so he was off. He did say that now Alex was a young frisky stallion that would make any owner proud and that his new life as a horse would be simpler than his human existence. Plenty of mare would love him! And that he had called the police to have him removed. He then left, waiting for his next owner and allowing Alex to wallow in the misery of his new existence.
