Johnny was satisfied with his new size; he tore off the shirt and looked at himself in awe. His broad body was a major turn on - he ran his large hands over his wide chest, moving down to feel his rock hard abs and treasure trail. He loved the feeling of added mass, and wanted more. Perhaps some other clothes would satisfy his needs. He was already the size of a wrestler - what more could he want? Johnny was too excited to care that he was already a very good size as he looked around the room for something else to wear.
His eyes fell on a red, sleeveless shirt. Perfect. It felt cool as if it had been left outside overnight. Johnny shoved his arms in and did up the buttons. He had some difficulty, due to the size of his hands. There. Johnny waited impatiently for something to happen. He was not disappointed, as he felt a cold sensation throughout his entire body. The cold should have frozen him on the spot, however it didn't. Johnny felt pressure building once more, and then the familiar feeling of growing...
However, this time he was getting taller too. Johnny felt and saw his limbs getting longer, his feet and hands growing once more, and of course the added muscle growth. Johnny went from wrestler to professional bodybuilder in moments as he felt his muscles bulge larger and larger. The shirt's buttons were straining, and eventually the top one popped off and clicked as it landed on the floor. Johnny tried to undo the rest of the buttons - but his fingers were too big to handle the shirt. So, he had to rip that off too.
Johnny felt rather pleased with himself, seeing that he had to duck to get through the door to the next room where there was a mirror. He almost had to go sideways through the door, for he was far too broad now. He looked in the mirror lustfully, running his hand down his firm 8 pack to his crotch. That had grown considerably as well, slapping against his leg as he walked.
The others! He had to get black to them. First he needed some normal clothes, though. Heading back to the other room he saw with a frown that he was going to have alot of trouble finding clothes large enough for him. He did find a pair of normal boxer shorts, however; squeezing into those and literally forcing his massive member in he could safely say he was decent.
