Tom desperately tried to think of nothing, or at least something to be happy with for the rest of his life. Suddenly, he smelt horse dung and thought of the time he found two horses making sweet love to one another.
While Tom was in his thoughts, Matt had noticed the swelling of Tom’s Ass. Every time he heaved, it grew. This occurred until the back of his pants exploded, making Tom moan and snap back to reality.
“Looks like someone’s coming along!” Said Kate, after looking at Tom’s enlarged package. It was an 11inch half human half horse cock, looking ready to pop. His balls pulsated with growth as they got darker and hairier.
Suddenly, Tom became very horny and began masturbating. He climaxed in a fury of whinnies as his cum covered the unfortunate pair. The cum had also sped up his transformation. His hands and feet had cramped and became encased in Keratin. His muscles had grown and he was now naked with the body of a horse.
“This isn’t re-“ Started Tom but his face began pushing forward like someone was pulling it. His teeth reshaped and he became unable to talk.
Tom made one last sound before he completed his transformation into a stallion.
“Glad that”s over” Said Kate, who went to get the Cum off her. Only to find it was absorbing into her skin. “Wha?” Said Matt before they both felt their hands cramping. They were turning into Horses too!
