As he proceeded through the library hunting for victims, he spotted the college's star football player in a carrel with some non-athletic student. It was obvious that the big guy had a tutor. Jim, the quarterback was six foot three inches and weighed 210 lbs. The other guy Rich was 5'11 and weighed 150.
He moved closer to hear what was being said.
"Whoa, so that's how that formula works? Gee, thanks, Rich, I really appreciate the help," said the footballer.
"You're a bright guy, Jim, you just need to exercise your mind, as well as your body," Rich said turning the page, "Now let's try a different problem."
Todd aimed his device, he knew it was cliche. He fired. Jim grew about 50 pounds of muscle bigger, and his IQ took a nose dive. He also felt his irritability level rising as Jim's testosterone levels soared.
"Problem?" Jim asked angrily staring at the book's page. It all suddenly seemed like gibberish to him. Was Rich making fun of him?
"Jim, you okay?" Rich could tell something was wrong.
From his niche looking through a bookshelf, Todd keyed in more commands and aimed at Rich. He grinned wickedly.
Rich shrank in his clothing down to 5'2", and 99 lbs. His vision blurred, and suddenly he was wearing taped eyeglasses. His voice had turned all nasally.
"This stuff make no sense," complained Jim brutishly. Jim grabbed Rich's collar and loomed over the smaller man.
Todd chuckled, "Maybe too much caveman?" he said to himself.
At least he thought it was to himself. He hadn't heard the other person come up behind him, and observe what he was doing. A hand reached for a book from the shelf behind him. It was a big 4 inch thick tome, another hand helped lift it.
"Almost forgot about their dick sizes. Let's see the football player's jersey say 14 on it, so we'll give him a 14 incher, and nerd boy? Hm? Maybe 1/2 inch?" he whispered to himself as he aimed the device.
WHACK. The book came crashing down on Todd's head. His chin hit the bookshelf and everything went black.
When he came to, Todd found that his device was gone. He felt mostly the same, but had a disturbing feeling that he wasn't quite the same. The device must have been used on him, he felt certainly, but he couldn't figure out how, or by whom.
He looked through the bookshelf, and was surprised to see that the jock and nerd were still as he left them physically, but seemed to have returned to their former cordial state.
"So the answer is four hundred fifty two thousand?"
"Yes, Jimmy, you got it right."
"Hooray," said Jim eagerly, "Does that mean I get my reward, Master Rick?"
Todd raised an eyebrow as the 6'5" muscle man dropped to his knees at the feet of the 5'2" nerd, and licked his lips.
"Yes, Jimmy, you've earned your reward," Rich answered pulling out his tiny cock.
The response in Jim was instaneous and obvious, his 14" boner not only tented his jeans but pushed out the lower part of his shirt.
Someone must have added to Todd's changes, but who. Then Todd glanced down and was horrified to see he too was rock hard. He decided he should go to the bathroom to jack off, but discovered he couldn't leave the spot he was in. He tried to think why he couldn't leave, but the only answer in his mind was the firm command "Stay, boy."
