Josh watched his brother's face express the pleasure he was feeling. He looked down at the spellbook and realized the spell continued on the next page. He had only performed part of the spell on Ric. There was nothing more to do now than to watch his brother change into whatever less than half the spell would do to him.
Ric felt warm all over, around his young dick mostly. He looked over at his brother who seemed worried. Ric was concerned, what could be happening to make Josh act like that. He looked down to watch the changes as they began to take place. Ric had woken up this morning at 5'1 with short dark brown hair, hairless arms and legs, and a cock and balls that had only begun to develope, dressed in loose canvas shorts and a XXL shirt he had for sleeping in and no socks or shoes. It felt like pins and needles were being stuck in all over his body, but it didn't hurt. He felt his whole world get a lot smaller, very quickly. Ric examined his body, his shorts now ended above the knee and his shirt stopped mid thigh even though his small frame was still swimming in it, when this morning his shorts went almost mid-calf and his shirt just above that. He lifted up his clothes, his legs looked very thin, but muscular, like a young runner or swimmer's legs might be. In fact much of his body looked that way, his feet looked like they belonged in a pair of size 11 shoes. He had gained 8 inches in height, but not a single ounce more in flesh, only bone. It was like he had been cut out of his body and had been stretched over Mr. Mendes' skeleton.
Mr. Mendes-now-turned-Ric, had begun to wake up. He looked over to see Josh holding an ancient looking book, and Ric, or who he thought was Ric. The boy in front of him looked much taller then Ric was, although Mr. Mendes couldn't tell if the boy really was taller or it only seemed that way because he was on the floor as well his own transformation, which he wasn't entirely aware of. Mr. Mendes stood up, and examined his body. It wasn't his, not even when he was younger, he looked at one of the mirrors he had hanging in his living room, he was so short now he had to jump, and even then he could only see his head, while before he could see down past his neck. All he needed to see was his face, it wasn't his! He had glimpsed the face of his student, Ric. He checked out his naked body, his tiny arms, his smooth legs, his narrow chest, and his small hands and feet. They all belonged to Ric. Mr. Mendes noticed his young teenage cock was starting to get hard as he rubbed his hands all over his new body. He was realy starting to get horny, all those hormones had rushed into his system the moment his balls shrank. His new cock was cut. He had never experienced a jack off like this, in his own body he had foreskin. He sat down and placed a pillow on top of his throbing little member. He started to thrust himself into it. He let out an agonizingly gutteral moan of pleasure.
Ric watched Mr. Mendes play with his new young self and get hot over the body he was in. Ric looked down to watch as the rest of his own transformation continued. His dick twitched. He akwardly pulled off his shirt and shorts, he still wasn't used to his new height or his thin, lanky arms and legs. He wanted to watch what he expected this transformation was going to be about. Ric waited a few more seconds. His dick twitced again, and again, this time harder than before. Ric grunted loudly each time he felt his cock growing, like it was being yanked out of him again and again to a soft 6 inches, along with a little more girth. His balls felt very heavy as they each balloned to Mr. Mendes' former size. Ric was still waiting for the rest of the transformations to continue. He wanted to see his body sprout the hair he had been itching to see since he had began puberty, for the muscles to start growing, and for his cock to finish widening. Nothing happened. It was like only a part of the spell was complete. Now it looked like he had the height of a 17 year old, but nothing else made him look that mature, except his organ. He still had his 13 year old face and muscles, only they were stretced over his new bones. His new height and large package made that little bit of hair that was around his cock seem even smaller now. He didn't know how to feel. He hadn't become Mr. Mendes, like he had wanted to, but he had grown much taller and had a nice piece of equipment hanging down between his legs, he could even stay like this, he thought, his mom would just think he had a growth spurt over the summer. Besides, no one in his Jr. High would tease him about how much hair he had when he was 3 inches taller than everyone else and had a bigger dick than most of their dads did. I'll probably grow the hair on my own, Ric thought to himself, but if I still have the rest of puberty to go through, does that mean I'll get even taller and my dick and balls will grow even more? This was better than becoming Mr. Mendes, he would be the tallest person in his school, or even in his town, not to mention the biggest down there. Ric was happy with this change. He looked way down at his now very little brother. Josh was standing there, almost shaking, afraid that his giant of a brother would be mad at him for messing up. Ric smiled and gave his brother a bear hug. "Josh, that was a great idea! I'll never forget what you did for me", said Nic. Josh breathed a sigh of relief, Nic had thought he had done only a part of the spell on purpose, as a gift, not that he had screwed it up. Josh fell on to the sofa, relieved and exhausted, he closed his eyes, and slowly began to drift off to sleep. So there they were, three boys in a house that belonged to a person who no longer physically existed. Josh, dozing on the living room couch, his brother Nic who was really Mr. Mendes transformed and at the moment having a dry orgasm with his pillow, and the new Nic, who had the height of a junior or senior in high school instead of that of an 8th grader and a cock fit for a porn star. If Josh and the new Nic wanted to stay together, they would have to do something about Mr. Mendes, Mom wouldn't know what to do with three sons, two of which were genetically identical in every way, except for height, cock, and balls.
