When you woke up again, you felt a strange sensation between your hind legs. Looking back for a moment you realize that hanging between your legs is a horse's sheathe, apparently while you had slept, while it hadn't restored your humanity, you had gotten your manhood back. It was a strange sensation to have one again after having been a mare for so long, but not one that was completely unpleasant. You nickered lightly as you realized that whatever this strange power was at least had given something back, and maybe if you could hold on just a little longer you could escape it.
That's when a smell hit your nostrils. You looked over at Jessica who was now awake and, more motivated by hunger than anything else, was grazing on the grass. You smelled an alluring scent coming from her as she swished her tail back and forth, you could see her wet folds winking at you enticingly. You could feel a growing desire to mount and breed this mare as your new horse cock slid out of its sheathe.
"Well, aren't you a big boy..." Vicky's voice said in your ear as you felt a hand on your shaft. You nicker lightly as you feel her pump it a little, the sensation just making things worse as your arousal grows. "Such a shame to lose a wonderful Broodmare like Princess. But I'm going to offer you a deal. You can smell her heat, can't you?"
You nodded your head, your brain was reeling as you felt her shaft stimulating her.
"All you have to do to lock this form is to mount her, breed her, take her as your first mare..." Vicky whispered. "Doesn't that sound good? You won't ever be the mare again, you'll be one of our prized studs and with this equipment you can have all the mares you want. Imagine it, any woman you want will become one of your mares. You know you want it, Prince, you know you want to take her. So why resist any further? If you don't, I'll turn you back into Princess."
As she spoke, images went through your mind of you mounting women turned mares. Each one getting more intense than the last as your mind wandered. It did sound so wonderful, no more worries, just a never ending supply of mares. You wouldn't be a broodmare, you'd be a proud stud and this mare Jessica would be the first one. You felt your human mind getting weaker and weaker, with the stallion side of you getting stronger.
You let out a whinny as your new cock spurted cum all over the ground. Jessica's head snapped up as she looked at you scared as more attendants gathered around her.
"Come on big boy, this is your last chance, do you take it or not?"
