Science. Ty watched dustin walk off to the class, his large muscled seemed even larger, as if what he had just done had made his muscles grow even bigger.
In science The girls admired his large size, and the guys were envious. But Ty wanted the other guys to get a taste of size. Ty walked to Dustin telling him his new plans:
"ok ty, i could live with being a little bigger, and i dont think my freinds would have a prob. either.."
Everytime Dustin touched another guy , they would gain 20 pounds of pure muscle and grow a little hairier. And everytime Dustin would speak to another guy, they would grow a half an inch taller and get a little more manly. And Dustin would grow the same way with every erection he got from the girls.
The plans were set. Sitting next to the buffed out dustin was his good freind chris, a 5'10" 16 year old weighing only 135 pounds. and the first thing Dustin did was ask Chris how he was doing.... Dustin then watched in awe as Chrises body began to beef up , 20 pounds of muscle was quickly packed onto his small frame, Chris notices "what the hell??? what happened to me?" now the 155 pound Chris admired his own defined muscles , who would he talk to next?
