Jeff spent the rest of his day trying to decide if having a horsecock was really worth it. Yes he enjoyed the extra girth and the feeling of cumming with such a big tool. But he wasn't too thrilled at the prospect of producing horse spunk for the rest of his life, or having his mom give him frequent hand jobs. And the fact that he got turned on by the scent of a mare's slit disgusted him.
Well at first. Because later, when he went to the bathroom to relieve himself, he found his piss even smelled like a horse's. Jeff's mind conjured up steamy memories of mares in heat, and the smells of their slick folds entered his mind. He was already holding his cock to aim it at the toilet. Jeff slowly began to rub his hand up and down. When he realized what he was doing it was too late, and he shot more horse cum into the toilet bowl.
There was so much of it, and it came out in such thick globs. It hit the porcelain of the toilet with a loud, wet, smack.
"Jeff, are you alright?" Jeff's mom shouted from across the hall.
"Ya, I'm okay." Jeff breathed. He shook the cum and piss off his softening cock. It wasn't easy stuffing his meat into his pants, but Jeff did it. He flushed the toilet and then ran back into his bedroom before his mom could ask him anymore questions. The last thing he wanted was for her to find out he was jacking off again.
Sitting down at his computer, Jeff pulled up the Chronivac again. And as he was about to change his body back to normal, there was a knock at his bedroom door.
