Jon's 8 year old brother, Mikey, walked into the bathroom, holding a pair of towels and fresh clothes. He knew he needed a bath, after all he had a birthday party to go to later that afternoon.
As he walked into the bathroom he noticed a pink bottle of some kind of substance sitting on the cabinet. Thinking to himself, 'a bubble bath sounds like fun,' Mikey proceeded to grab the bottle and set it on the edge of the tub. Turning on the hot water and getting undressed, he waited for a moment before unscrewing the cap and starting to pour the substance into the water. Unfortunately for him his hand was wet and the whole bottle slipped out and fell into the tub. Silently cursing as much as an 8-year-old could curse, he reached down and fished around for the bottle. It took him a few moments, but he finally grabbed hold of it and pulled out. Much to his chagrin, the bottle had been completely emptied. Even more to his chagrin, the bubble bath didn't seem to be working. Shrugging his shoulders, he simply climbed in the tub and began to bathe.
After several minutes of messing about and playing in the bathtub, Mikey washed his hair and then stepped out to try off. He felt a little woozy and almost overcome with the scent of lilac. Suddenly as he stood, he began to feel changes come over his body.
The first thing he noticed was that he was getting taller. Slowly but surely he grew, stopping out an an even six feet tall. Mikey was amazed as he stood in the mirror, and saw what was essentially still him physically, only stretched out by about two feet. He then felt other changes begin.
He saw his stomach slowly creep inwards as his hips flared out. He had to readjust his stance as his rearend became padded. All across his body he filled up, not at all in such a way that Mikey would expect a growing boy to do so.
"What's....ahem...what's..." Mikey was shocked as he heard his voice grow higher pitched, and sound exactly like a girl's voice. Frantically Mikey tried to make for the door, but stopped when he looked down at his hand and saw his fingernails growing out at an alarming rate. A few strands of auburn hair fell into his face, and he looked into the mirror to see his short, ruffled hair growing exponentially down to his backside.
He nearly screamed as he saw his face twitch this way and that like clay on a potter's wheel before finally settling on a very effeminate and rather angelic looking face. Before long, Mikey looked down to see that the area around his chest was getting a little puffy. Just as quickly the flesh surrounding it exploded forward, becoming a massive set of breasts that hung out from his chest, looking like a pair of overinflated soccer balls.
Finally, Mikey felt a sharp pinch in his groin area and instinctively felt down below. He wasn't quite sure of all the intricacies of what girls' had down there, but he knew for certain that boys were not supposed to have a hole in that area. Finally reaching the end of the transformation, Mikey grimaced and began to frantically flutter about, broderlining on a full out scream, before collapsing to the floor.
