The sight before Jeff's eyes made him panic like never before. It was a huge, muscular stallion with a prominent horse penis that swung between its legs.
His eyes were fixated on it in horror as he couldn't believe what Sally had planned for him.
Sally just laughed and unlocked the tree-bound stallion who immediately trotted over to Jeff. Before his terrified gaze, the massive animal approached him and began sniffing around his new female body with an eagerness that made his blood run cold.
Jeff tried moving away but was unable to do so because of his newly acquired hooves. He could only stand there as the stallion pressed himself against him and began probing Jeff's new vagina with its massive horse penis.
Sally laughed cruelly at Jeff's obvious terror before finally crouching down beside him. "It looks like we have a little virgin to take care of, don't we?" she said, grinning wickedly up at the sobbing man who was now her female pony.
Jeff tried to protest, but Sally just silenced him with a backhanded slap. "You chose this. You wanted the experience of living as an animal. Well, here it is. Enjoy," she said before turning away and walking off towards the house leaving behind her bawling pet on all fours in front of the stallion.
As if sensing he was free to proceed with the act, the horse wasted no time mounting Jeff and began to push itself into his new vagina with a wet squelching sound that made him cry out in ecstasy. The sudden pleasure brought tears to his eyes as his body instinctively reacted to the sensation.
"You're doing so well," Sally said, while the stallion was nudging at him with its nose before licking his tear-streaked face affectionately. "Don't be scared anymore, my little mare."
Jeff just sobbed uncontrollably and tried to get away again but his hooves made sure he stayed right where he was. All he could do was cry out as the stallion continued thrusting in and out of him.
Sally laughed again while walking back towards them. "Oh look, he's even starting to wiggle his new tail. He really is enjoying this," she said before looking down at her creation with a mixture of amusement and disgust.
As the stallion finished inside Jeff, both of them breathing hard from their exertions, Sally approached and reached out to pet the horse. "Good job, boy. You certainly broke him in proper, didn't you?" she teased, grinning maliciously up at her sobbing pet.
Jeff was trembling by now, his eyes completely filled with tears. He could only imagine what kind of horrors awaited him next, and all he wanted was for this to be over.
Sally just laughed cruelly again as she removed the rope from Jeff's collar before leading him back into the shed. "That wasn't so bad, was it?" she taunted as she shoved him inside and closed the door behind her once more.
