"I think just about anything," Jeff answered. "I haven't really tested it out too much. You're technically the first person I've used it on."
"Really?! Thanks lil bro!" Mike gave Jeff a bit of a noogie. "You're the best." He paused and gave it a second to sink in. "Yo... Can you make me more muscular?"
"I don't see why not..." Jeff said. He was having a bit of difficulty seeing his father as his brother. The dueling memories seemed to be conflicting with him and he can't quite figure out how to deal with them. In the light haze, he just does what Mike wants him to do and changes Mike to be built like a bodybuilder. Then hit enter.
Instantly mass began growing all over Mike's body. His average sized muscles instantly started to bulge further out from him. His thick arms only grew bigger. A large vein bulged out of his bicep and forearms. His massive hands grew calloused and hard. Two pecs ballooned out in front of him while a cobblestone of abs laid directly underneath. Wide shoulder and a thin waist gave Mike an unbelievably intimidating silhouette, but the smile on his handsome face instantly distilled it.
Mike's quads were fighting for space as his legs nearly doubled in size. Perfectly sculpted diamond shaped claves were right below them. His toes wiggled as they almost seemed to crawl forward as his feet only grew that much bigger. Mike threw up a flex, showing off his 20 inch arms and massive legs. He seemed to know how to perform the flex perfectly, almost like he was ready to go on stage. Jeff stared in awe at what just happened. He couldn't get over how defined every part of Mike was. And how easy it was to see as his 'bro' was still just in his underwear.
"Fuckin' sweet!" Mike leans over and picked up Jeff out of his computer chair and held him in the air. He has to be almost a foot taller than Jeff and weigh at least 100 pounds more. "Look how little you are!" He swung the other man around like he's absolutely weightless and then tossed Jeff onto the bed. "This is just about perfect..."
It took Jeff a moment too long to realize what Mike had just said. He sat up as quick as he could. "Mike wait--" But it was too late. Mike had already made something change.
