Darren Yates dutifully trotted down the hallway, off to secure the muscular Matt Hennson for the demonstration. Unbeknownst to him, Ty was monitoring the whole thing, mulling over what to do. Finally, he hit on it. Matt would be the "natural" bodybuilder, while little Darren would become the roided freak.
Ty decided to leave Matt be for now. The hulking young stud was already 270 pounds, at only 5'10"! Darren, on the other hand, stood only five feet even, and weighed a rather gangly 85 pounds. His transformation would be dramatic, to be sure.
As Darren reached the bathroom, he felt queasy. His stomach turned, and his body ached. He stumbled inside, on the verge of retching.
Standing in the middle of the room, in all his nude glory, was Matt Hennson. The powerful stud whirled around, looking to see who had entered. He smiled as he saw little Darren, who could barely stand it looked like. He was a bit annoyed though, as Darren seemed to ignore him, heading for one of the stalls, looking very sick.
"Y- you're supposed to go back to class... for the demonstration..." Darren managed to choke out, just as he began to hurl into the toilet.
Matt sniffed dismissively, then smiled. A chance to show off for the class? Excellent. He pulled his boxer shorts on, put his shirt and shorts over his thick arm, and strode down the hallway, planning to give the class a show they wouldn't soon forget.
In the stall, Darren was so sick, he didn't even hear Matt leave. When he finally stopped throwing up, he flushed down all the puke, and sat on the toilet, shaking. "What... so sick..." he groaned. Yet he was starting to feel better. Much better, in fact. He stood up, and walked out to the main area of the restroom, and washed his hands in the sink. As he washed them, he noticed that his veins were standing up on his hands and arms. He blinked in confusion, looking down at them. They seemed to... throb.
Matt swaggered back into the classroom, a huge grin on his face, nothing but underwear on his body. Gasps went up, even among those who had seen the young god shirtless before. He strode up in front of the class, raised his arms, and flexed, his thick biceps rising, hard and round and powerful. Coos of amazement erupted from the class, as Matt moved from one pose to the next, showing off his gym-wrought physique, every strong muscle flexing impressively under his smooth skin. His ten inch tool jutted from his strong hips, tenting the underwear dramatically. When he showed off his legs, he pulled up the cloth around his legs, showing off the top of his powerful thighs. It also emphasized just how big his dick was. The teacher, Mrs. Brown, had to sit down at her desk, fanning herself with a stack of papers. Ty was enjoying the show as well, but not as much as he was enjoying what was going on in the bathroom.
Darren stared in the mirror, wide-eyed. His body was shifting under his clothes, changing. He was getting taller, for one. Although it was hardly the kind of thing one would expect from steroid use, Ty had decided that the comparison would hardly work if Darren remained five feet tall. So little man grew, until he stood 5'10", just like Matt. And then the muscle. Darren's body changed, as if he had spent years pumping iron, ever since he was ten, just like Matt. The difference, though, was steroids. Darren's muscles bloated, becoming thick and heavy and hard, veins rising up over them. They swelled, larger and larger, tearing through his clothes, shredding the fabric until he stood in the room in nothing but a pair of painfully tight briefs. Inside the briefs, his dick grew hard, eight inches of solid meat, while his balls shrunk, their function replaced by the chemical cocktail racing through his body. His gut protruded, rounding out, covered with rock hard abs and thick veins. His pecs swelled further, and his nipples itched, becoming sensitive, jutting out further. Acne boils began to form on his face and back and shoulders, present but not overwhelming. His cock tented his briefs painfully, as lust consumed him. He looked up in the mirror, and staring back at him was a 330 pound hulking brute. An aggressive grin spread across his face, as he raised his huge arms and flexed, the monstrous biceps rising to freakish size. "Oh fuck yeah..." Darren groaned, his voice low and powerful. He turned, heading out of the bathroom and down the hall.
