It was all of an hour before my mate walked to one side and pulled free. I laid in the pasture for a while as my ass recofigured back to normal. Once my pants were on I stepped across the fence and started for Jon's house.
Looking back my mare mate whinnied at the fence for my return and round two. The stallion mate walked to the barn tired of his romp. I got to Jon's about four in the morning, tired dusty, and dripping of pony semen.
"Morning my friend, said Jon coming into my room. It's Fri..day, Hey what's this man?"
I sat up in bed as my friend's eyes went wild and pointing at me he looked upset. "Why have I started to change to the Malmute?"
"Jon starred, Change yes but not a Malmute, looks like horse to me."
I bounced out of bed and looked in the dresser mirror. There looking back at me was two long ears. Furred and pointed they reminded me of the pony stallion. My nose was black skinned and my lips hugh. As I grinned I saw teeth of a horse. The black furry hide went down my neck to shoulders and chest.
Stepping back Jon yanked down my boxer shorts to see what else had changed. Indeed I was on my way to be a horse. Black hide and soft brown fur covered everywhere. Looking backwards I felt Jon pickup my horse tail as I had a sensual chill.
"What happened last night as you walked, asked Jon."
I thought for a good minute and decided the truth was the only way. I told each detail and as I remember the thrill of being in the mare my new sheath pushed forward a cock of SIZE. I stood looking every bit a morphing human. Jon asked which farm it was and I told him as much as I could remember. Jon then called Wilhelm and told my story again.
All this sexual lusting and my inner desires turned my horse cock rock hard. Seeing what I now sported, the lenght, size, sheath, and a flared flanged head that looked neat. I felt such a need I walked into the bath and started mastubating the beast. Surge fter surge of thick semen shot from the end and stuck on the wall above the toilet.
"Hey are you alright, I have news from Wilhelm. He says that having sex and being fucked is good now instead of being a dog you will become a horse."
