It was a nanny...but her smell clouded Kenny's deteriorating mind. His dick was so hard he thought it would explode. He was now obscenely hunched over at the waist and struggled to stay upright. He stepped closer...slowly. He knew this was the moment of truth...but his dick kept pulling him closer to the nanny. Her moist black lips were glistening in the sun. He could see his muzzle as it pushed from his face further...he could feel his insides churn into new organs. He tripped and fell. He tried to push himself up...but he couldn't get on his feet (hooves). His hands were still not cloven hooves yet...but he couldn't stand. He was an awkward sight. His back-end raised higher then his front because his front legs were not yet fully formed. As he struggled to get upright...he felt a strange sensation over his butt...as his tail matured into a full goaty tail. He also could feel the weight of his horns as they grew out of his head. But his dick...was still commanding most of his attention. He awkwardly moved on his 2 hooves and 2 hands towrds the nanny. He got real close, he could almost lick it then he heard a voice...it was John.
This is it Kenny boy. One last chance to turn around and leave. Once that pecker of yours hits that nanny pussy...you are my barn animal for all your days. Now be a good boy and turn around if you can. Or is that dick of yours going to seal the deal?
Kenny shook his head and tried to focus on what the words were. He kind of understood what John was saying but the words were lost in his mind. He couldn't quite grasp what he was saying. He realized that his mind was slowly going the way of the rest of his body...it was going to the goat world and his new brain wouldn't accommodate the English language. He sniffed the nanny and then pee'd on the ground. He became even more aroused. He stumbled closer...his front legs now starting to bend the proper goaty way and becoming more in line with the rest of his body. Standing on two feet was no longer an option. Kenny placed his front hooves around the nanny and positioned his dick against her backside. Kenny could no longer see his dick but he could feel it. It felt hard and powerful. He knew where to stick it as he slid against her moist hole and sunk in. As he pumped his first few thrusts...Kenny could feel his body adapt to the final changes. He opened his mouth tho speak and all he heard was a goaty cry of BAAAAA! He pumped that nanny with all his might...his back hooves dug deep into the soil and exploded deep into her. Exhausted, Kenny dismounted and fell onto his four cloven hooves. He still remembered who he was but he could not speak. He heard John speaking and could see him talking but did not understand a word. His brain was full fledged goat except for his memories. Kenny walked away on all fours towards the barn. On the way he pee'd again and took another goaty crap. The smell of the excrements did not bother him nor did it bother him that he couldn't clean himself. He was all animal now.
In the morning. Kenny awoke and tried to stand on his feet. He struggled for a minute or two before he realized what had happened the previous day. He rolled onto his four hooves and shook himself. He tentatively walked over to the grain box and trough and filled his belly. He then walked over to pee and crap. His balls swayed as he walked and he could feel their goaty fullness and bigness. He knew they no longer contained anything human. His cum was now all goat. He could feel his goat penis inside the sheeth. His goaty penis was pink and it was big big and it was strong. As he thought about it he became hard again. The penis creeping out of the sheeth and banging against his goat stomach. Kenny flexed his behind so the penis bumped against his stomach and he came in a huge shower of goat cum. He should be embarrased but he wasn't...it felt wonderful and he felt strong. He walked into the pasture and felt his whole being...horns, hooves, penis, tail, sheeth...and wondered why he was so afraid. He was very pleased...and as he thought...that wonderful and powerful toy between his legs poked its pink goaty head out of the sheath again...Kenny smiled to himself as he walked on his hooves to the nanny so he might unload another shower of cum into her beautiful black pussy.
