The brothers caught their breaths, taking in the changes that they'd just gone through. It felt natural for both of them, each felt as though he'd always been this way. There was no difficulty in standing on their new cloven hooves.
They both remembered that they hadn't always been this way and what had caused it. But they remembered new things too. They both remembered how every human made the transformation into a mythical beast when they hit puberty. They remembered that inter species mating was possible and completely acceptable. Complete nudity in public for transformed people was the norm and not considered the least bit scandalous. But they didn't remember what happened when identical twins changed....
"Why did it stop?" Josh asked, "Why did't the hair grow on our buts?"
"I think it'll keep going soon, it took a little while when Ruth and Angie changed in class last week." Ric looked up form his legs, puzzled. "How the hell do I know that? and why can't I rememebed what happens next? Oh shit there it goes."
The fur travelled further up his legs, enveloping Ric's ass and cock. His already ample cock stiffened and shot out, pulling his loincloth off. He gasped as his balls grew to the size of oranges, filling up with cum like waterbaloons. His modest chest turned into a six pack, hair burst out that Austin Powers would envy. A more than decent beard grew out of his chin. Throughout all of this he had grown taller, topping off at six foot three.
Josh looked in envy at his brother's new body. The gears in his head were turning, if his twin brother had changed like this than what coulod he expect? "Ric, how do you feel man?"
Ric looked wildly at his brother, his eyes filled with lust, "I feel good, you?"
"I'll feel good soon too."
"Yeah you sure will," he smiled deviously, having remembered what happened with twins. He couldn't wait to try the moves Angie had pulledon her sister after they had transformed. Mind you his cock was modest compared to a centaur's. "Can you feel it yet?"
"I can feel it!" He could feel stirring sensations in his cock, he looked down to see it tentpole his shorts. His grin faded when, instead of growing it seemed to fall. He pulled his shorts down to reveal the scene to his brother: his cock had dissapeared, been sucked into a cavity between his legs. "What the hell? What's happening?"
"You just need a little help," he grabbed his brother's arms and forced him down on his knees. "This is why the male always changes first."
Josn opened his mouth to scream, Ric used the oppurtunity to force his huge dick into josh's mouth. He could barely fit the head in but it was enough. Josh began gulping back the cum that shot out, wishing to top but unable too. After what seemed like forever Ric ran out and lightly pushed his soon to be sister back.
Josh stood up, stuterring as he tried to think of something to say. His remaining male insticts were fighting with the rising female hormones. "Oh no," he grabbed his chest, stroking his nipples. "Oh no no no."
His chest pushed out as he grew breats. Josh pushed down as if trying to stop them but it was no use. They filled out to a D cup, she gasped as she actually felt the milk rushing into them. The fur climbed her legs, covering her new pussy and wide hips. His hair grew amazingly fast, in no time at all she had a mane of blonde hair that fell down to her tail.
Josh took stock of her new body, her hands still on her breasts. "Oh my God," she accidentally tweeked her nipples and gasped. "Oh my God," she began to breath heavily as she stroked them harder and harder. She moved one hand down and began punching into her pussy. Josh was completely lost in the sensations of his new body, not realizing that her brother was watching her.
