Joel contemplated to jack off to his new package just yet, as a idea soon sparked into his mind as if he was to become a bit more stallion, as a bit more could increase his pleasure.
He soon took off his clothes, revealing his large cantaloupe balls hanging before grabbing the stallion vial from the box. He soon started to drink half of it, so he wouldn’t become a full on stallion horse. He soon started to feel dizzy, before the changes began, he soon felt his muscles tensing up as if he was lifting something large as his muscles started to become more muscular in a few moments he looked like a body builder, Joel loved the sensations. He looked down to see his package growing in size the transformation is working.
He soon began to feel larger as he grew a few feet his head now a few inches from his roof. As dark brown fur started to grow on his body soon becoming accompanied by a horse like tail. Joel feet soon started to change as his feet soon grew larger before fusing into a single hoof as his legs soon grew a bit more. His arms started to grow patches of dark brown fur covering his hands not altering a lot unlike his other parts. He soon felt his face started to stretch as his nose and mouth fused to become a large snout of a horse before his whole entire head was covered in fur. Last was his hair which changed growing into a beautiful mane completing the transformation.
Joel looked at himself in the mirror with delight he was a anthro stallion. He soon slowly looked down to his package seeing if it now complete which now his balls the size of a large watermelon. He wanted to see his cock he soon started to feel in the slit as he soon started touching his cock his mind raced filling with pleasing thoughts. As the feeling started coming back, pumping itself the head soon popping out the size of a cantaloupe as it started to pull out it inch by inch he could tell it was longer as it passed 30 inches, his thoughts pushing the cock further and further out ending about an astounding 80 inches. It was at the height of his neck. He soon started to rub it which barely he could clasp as his middle and thumb were 1 inch away, as a new sensation sweeping him. He couldn’t control it and started to rub it even more flailing it around like a sword as it began to climax as droplets of white started to come out one last rub and a hose of sperm ejaculated out of his cock. Going on his blinds, bed, door. Practically the floor. He tried to stop it as the scent of his sperm grew more potent as his whole room smelled like horse cum so closing his eyes he opened his mouth and covered it as cum soon shot into his mouth. He soon started to gulp all of it in as the cum started to over flow going on his body. Couple of minutes of gulping the climax ended. As his cock slides back into his slit his mouth covered in cum. He needed to breath, he started to look into the vial box to contemplate wether to change back into human or stay a horse.
