Jeff woke up, feeling slightly groggy as he did. He got up from the bed, and felt very dizzy. He cut his foot on the bed, and looked down at them. ARE THOSE MY FEET? he thought. Everything looked a bit different. His legs were covered in black hair, that was almost normal for a boy his age. As he looked in his mirror, he noticed a bulge in his boxers. That couldn't be his dick. It was slightly larger, surrounded by thick black hair, which traveled up to his belly button in a slight happy trail. He no longer had hair on his chest, but he noticed that his pecs had grown a bit.
He saw a bit of stubble on my chin, but it wasn't very thick. He had little sideburns, which then made him look up at his hair which was thinning. He pulled a hand through it, and a big clump came off, revealing short little black hairs. As he continued to the washroom, he felt a huge cramp, and keeled over.
He must have passed out for about a minute, when he regained consciousness, and he rushed into the bathroom. His hair had now completely fell out, revealing black stubble. His eyes were now light blue, and his skin was slightly tanned. His face was more prominent, and his chin poked out. He looked at his arms and legs, they had grown muscle. His chest was now sporting big abs, as he admired his new 6 pack. He looked exactly like Tom. "Cool" he said in his new voice. He had to make an escape though, since his parents would freak.
One more look at his sideburns, and his stubble on his chin an cheeks. He ran right out the door without anyone noticing anything.
