Tom's eyes were going back and forth and circles in his head so fast, trying to think this all through, that it distracted almost from what else was occurring to his body. Despite every attempt to tense his muscles, they only grew bigger while mass and thick hairs were starting to grow down his back.
"I can't, we won't, there has to be a way to stop-p-p-p this," Tom sobbed as he felt an enormous swelling if his ass that broke with it more popping noises. His head down, Tom could see his knees were inhuman while his foot were now just black hooves with sock remnants around the top.
Kate backed away, taking in the sight of him as Tom's shirt was starting to rip as every breath seemed to expand his growing ribcage. Kate blushed when she saw Tom's rear end again, it looking- save some added hair and tail growth- like a mare going into her first heat, only the front was attached to a struggled college aged boy.
"Please, anything," Tom begged. His nervous steps were now clops on the hard tiled floor that his cheap throw rug did little to mask.
Kate shook her head. "You have to understand, I was really, really angry at my ex so this spell was a doozy. You're more mare than Tom, Tom," she added as gradual moving of his nipples south had been lost the shuffle but the growing teats and small sack gave little room for argument as to gender, or even species. Tom closed his eyes hard, trying one last time to concentrate and wake up from this nightmare.
Instead, in his attempt to control it all, his bowels gurgled and his asshole puckered open. Several turds rolled out before a stream of hot and lustful piss dripped out afterwards.
"I'm sorry but you really do have to accept this," she said, her sleeve covering her arm to try and save herself the smell, "you're spending the rest of your life as a horse, in your case a mare, instead of studying History or Art or whatever you were doing."
Tom's head dropped again, still human save for the horse ears. Looking under him was a disgusting display that may him dizzy to think was him. Picking his head back up, there were tears in his eyes but his lips quivered open.
"I'm gonna be a fucking mare," he said with defeat. Matt, who had changes to keep up with Tom's only having to battle a throbbing horse member and the surge of hormones that his new testicles were sending to his head. That's why when Tom emptied himself, what disgust his human mind had was overwhelmed by senses of relief and arousal.
Relief since seeing Tom do it, Matt could back into the corner and release his own load of three times what Tom did. Horseshit behind him, his nose then filled with a smell he thought would be a barn but instead he was gifted arousal. The warm scent of a female in heat so near and available.
"Good girl," Kate said, patting Tom on the back which answered with a few more morphing pops and cracks. "And good thing too. I think Matt is about to take you two to the farm. I guess I'll leave you two to it." She walked around Tom, his neck starting to elongate, and waved kindly, doorknob in hand. "Sorry again. You two enjoy the rest of your lives."
With one last smile to either, she shut the door and was gone. Tom was left looking at the mirror mounted on the either side of the door.
His body was pure mare, from feel and look, from shoulder down as a brown and white dappled fur set in over him. His head was unchanged, save those waggling ears, but he knew that wouldn't last. Behind him, wobbling along on new legs, Matt was trying to look calm, though his eyes were purely on Tom's backside.
