Standing there taking deep breaths of Missy and her heady scent whille finding the air filled with the perfume of the other horses. His mind was working overtime, he felt the radical urge to stand and mount the mare, but for as much he lusted for her part of him wanted to step away.
Two stiffening hands stroked his extended shaft as he tried to think of which course of action would be the better.
Shaking his growing head, the long mane on the back of his neck flicked and flopped about granting him yet another new sensation. Shivers and shudders raked down the length of his growing body and legs. As each series of shudders wriggled down from head to toes he felt his true self giving in to the change toward equine form and life.
Missy turned her great head looking down the large length of her Percheron body. She whinnied her pleading wish to be at last satisfied and at peace with her own passion. Snorting as if to show her lack of empaticent feelings, the other mares began to make simular sounds.
Jeff began to walk in circles like any common animal might that is undecided about some course of action.
Like a zap of lightning striking him he suddenly stopped, standing upright as tall and stiffened of frame, he felt the creeping sensation working now up from his legs, to groin, and heading along his spine.
"Yer thinken' about it won't stop what is to come to pass, Boy!" said the old man as he was now watching Jeff from several feet away.
Jeff turned to look his direction and try as he might to speak his mind the only thing he could muster out was the sounds of a colt longing to make its thoughts known. Now feeling the ultimate sense of worry as his human ability of speaking one's mind had also changed over the line and become as if he was born an equine.
"Missy came here recently, she was originally a gay man and by the designs of the one who changed him to her was given in to his deepest passion and desires. I think he has now discovered his true self and being as a mare can realize his potential in life!" said the old man.
Jeff was not so far go over the edge into bestial life and form as not to recognize the sudden change of speech pattern on the old man. He had for some time sounded like an uneducated man with his hillbilly style of talking. Now it seemed he was talking with a very well educated and smooth sort of speaking, this was making Jeff have alarms sounding in his head.
Missy was not to be outdone, upstaged, or let down, from her poised round rear jetted out some of her female juices. The scent which prevailed there was strong and this made it just plain acrid.
Instantly Jeff turned toward the mare his head ablaze with her rank scent. Taking deep breaths of the musky odor hhis penis came to red alert status. A step closer toward Missy had Jeff placing his stiffening now blackened hands on her tall round rump. Her short docked tail whisked over the dark rear end of her otherwise light and dark dappled gray haired body.
One long last whinny to help Jeff make up his mind was all he needed. Another step forward and with his shaft standing in an upward direction he let it touch the lips of Missy's black equine sex.
The flatened and flarred end of his horse's cock pressed at the softened lips of Missy's sex. He looked down watching the pink end of his shaft enter into Missy and then inch after glorious inch went slidding into her warm depths.
Even standing eight feet tall Jeff allowed his enlarged self to lay over the huge rounded rear of Missy's Percheron body. His cock in so deep the lips of his sheath were now pressing past Missy's vulva and would have entered her if it were long enough. A slow slidding in and out action of Jeff, his pelvic region making the moves as his cock felt the rapture.
The distant sopund of the old man chuckling to himself as he watched a young man accept the lusting desire of what a stallion knows, while then becoming a stallion in body, mind, and spirit.
