Jeremy quickly ducked into the washroom, entering the same stall Ryan had. He locked the door. Just as he did, he felt extreme pleasure all over his body. The changes had begun. Jeremy quickly stripped down naked.
He groaned as his shoulders expanded sideways, giving more room for his soon-to-be-bulked-up body. His arms began to expand and his muscles swelled. His biceps became much bigger than they had been before. His pecs began to swell, gaining muscle. His nipples darkened as his chest darkened a bit as well. His arms and legs began to crack as they lengthened. His hands grew, as did his feet.
Jeremy started growing taller and taller, his chest widening to make rom for his torso as it got longer and wider.
His feet grew, expanding to a size 14. His legs bulked up, gaining massive amounts of muscle. His penis was growing too, bigger and longer until it was nearly 3 times it's original size. Jeremy had a feeling he was going to like this body.
His spine was extending and crackig until he reached 6'7. He felt his neck swell with muscle, becoming thicker and thicker, like the rest of his body. He flexed his chest and watched his pecs and abs push out, incredibly defined for a 17 year old. Jeremy was enjoying the feeling of increasing size and strength. His quads inflated.
Then, Jeremy's hair grew out, becoming a slightly darker brown. His eyes changed to Hazel. His features became warm, his skin lost every tiniest blemish, and his jaw grew out a bit. He had become the boy.
Jeremy was lost in ecstasy. He was ready to meet the girls.
