Josh gripped his new man sized penis and felt the ripples of pleasure flow through him. Marco looked down at his tiny prepubescent cock and held it in his hand, a look of total disbeleif etched on his face. Only a few moments ago he had been one of the biggest men he knew of, and now, there were 13 year olds with bigger cocks. Josh looked up at Marco as he stared down at his now child sized dick and wondered what else he could take. That was it, he was always having to look up at people, he was shorter than everyone else, shroter than his brother, then the other kids at school, everyone. Marco was 6'3, tall by anyone's standards. Josh opened the book and murmered the spell. Marco's tiny little dick became painfuly hard and pointed up at the ceiling, the head of the penis only poking out of the massive pubic hair it had been hidden in before. Marco felt a sudden drop, like when a person misses a stair and goes to the next one below. Then he felt it again, it gave him a strange feeling in his stomach, but his little boner was throbbing now. He couldn't take it anymore, he had to do something about his horny little pecker. He wrapped his short stubby fingers around it, wait, short? stuby? The lurching sensatiopn had ended a couple of seconds ago, he looked over at Josh. Josh's stolen rod was already erect and dribbling precum. Marco realized he was looking him in the eye. Ignoring Josh, Marco ran over to a full size mirror they had brought out the night before, and saw what had happened to him. He still had all his body hair, and all his muscles, only now, he was 5' tall. His muscles and veins popped out all over his body, his body hair, which had looked normal with his old height, was now bunched up on his greatly shorted arms, legs, and chest. Marco looked back over at Josh. Josh had his oversized cock in between his two tiny hands and was thursting it throught them. Sweat had broken out on his forehead from the massive jolts of pleasure he was receiving. Josh moaned out loudly, Marco could see the changes begin on the boy. His toes inched thier way out, growing longer and longer, the rest of the bones in his feet followed suit. This 5', 12 year old kid now had feet that would fit into Marco's size 13 sandals. He watched on as the boy let out an even louder moan, his body spasming with the pleasure from Marco's cock and the spell. His shin bones had begun growing, Josh rose up a few inches, he was now taller than Marco. The changes continued on up his body, lengthening his thigh bones. Josh began ot whimper, he was feeling the greatest orgasm ever, better than most men ever know of, and this was one of his first times. The spell suddenly expanded Josh's tiny pelvic bones, causeing his tiny little ass muscles to be stretched tight across his new larger frame. The spell seemed to jump to his hands now, they were gettin longer beginning with his fingertips, and traveliong up his smooth hands. Within a matter of seconds his hands were now the size Marco's used to be, big enough to palm a basketball without a doubt. The spell now seemed to move up the boy at both his arms and his torso. Josh's wrists were getting longer and longer, as his waist seemed to be getting farther and farther away from him. It reached his upper arms and chest at the same time. The muscles he had there were all being pulled to their limits as his skeleton quickly grew out. His thin neck seemed to be getting even thinner as the bones there grew. Finally, it had ended. Josh was 12 years old, with a monster of a cock planted on him, with a height of 6'3, but weighed in at an astonishing 112 pounds. Looking up at him was Marco, a 25 year old measuring up at 5 feet, and paired with a tiny boy dick on him, however, he still had all his muscles, which brought him to the weight of 210 pounds.
