Rob began to wonder if he did in fact copy that jock's arms as his own, if he could copy other body parts. If he was going to join the rowing team he would need more than just powerful arms. He decided to cut through the Athletic Building on his way to his next class in the new Chemistry Building out beyond the gym.
As Rob cut through the weight room, he spotted the torso he wanted. It belonged to William Beuchamps, and he was on a bench lifting a barbell with Stuart Wicklow spotting him. Instantly as he thought it, Rob saw Bill's perfect pecs and abs dwindle to be replaced by Rob's old one, even as he felt his own shirt tighten over his swelling chest and shoulders.
Bill still with his powerful arms, but no shoulders or pecs to speak of, started to lose the weight he was pressing. Stuart caught it, and laughed.
"I told you that was too much weight, Popeye. You spent too much time building those big guns and not enough on your shoulders and chest."
"What?" Bill gasped sitting upright and his 11 inch cock slipped out the leg of his workout shorts, and patting his bulge while rubbing his other hand over his now packless abs, "At least that's still where it's supposed to be!"
Inadvertantly, Rob glanced enviously Bill's cock, and caught sight of it pulling a wicked witch of the east number and disappearing into the shorts the way the legs of the witch vanished in the movie. Rob's own crotch suddenly was straining to contain his new bulge, he'd need to get jeans with more crotch room.
"If you want to lift weights like this, you need to wait until you have muscles like that guy," Stuart said nodding at Rob. That was Rob's cue to exit. Bill never looked up, as he stood to pull open his waist band to get a better view of his shrunken organs. His black haired pubic hairs were now sparser and blond. Rob glancing over his shoulder at Bill's taut sculpted butt, figured he might as well match.
As he left the weight room, Rob's jeans filled out in the back replacing his former flat butt with a rounded more muscular one. He chuckled thinking of Bill Beauchamps standing there with huge muscular arms and legs, and a wimpy torso. He did look like Popeye. Of course, all the added muscles were making Rob's own legs ache from carrying all that extra mass. As he climbed the stairs to his Chem Class, he knew he'd have to get some new legs to carry his new mass.
