Karen led Andy to his bedroom. He may have had the body of an 18 year old and the cock of one too, but she reminded herself that he was still a child as she took in the gorgeous contours of his biceps and the shocking bulge in his pants.
She put him to bed after he put on his pajamas, which were now much tighter and went back out to check on Jesse, who had gotten up and was icing his face with a bag of frozen peas he’d gotten from the freezer.
“I don’t know what to do,” he said looking at her. “Even if I do what the Madame told me and get an inch, he’ll get two. He’ll always have a bigger cock than me.”
Karen was getting desperate to have her boyfriend back, “You have to be nicer to him. Another growth spurt like that and he could force you to do things to him.” She started to feel a little wet imagining just how massive Andy’s cock could get. “Let’s watch some tv while you ice your face and then go to bed”
Andy woke up in the morning feeling the strain of his pajamas even tighter than the night before. He stood up out of bed and nearly hit his head on a shelf above him.
Looking in his bedroom mirror for the first time he was shocked. Thanks to Jesse trying to fight him, he had grown considerably. Andy had to be about 5'10" at the age of 14. He knew he had gotten bigger the night before, but he must have grown slightly more after he went to bed. He tried to take his pajama shirt off but fumbled with it and just tore it clean off. Underneath it was an incredible set of pecs on top of an absolutely cut 6-pack. He lifted his heavy arms and hit a magnificent double bicep pose. He realized that checking himself out was making him hard, so he pulled down his pajama pants leaving him wearing nothing put a pair of stuffed underwear. His quads had doubled in size and his calves were as toned as a soccer player's.
Andy laughed a little bit thinking about how he'd never even been to a gym or worked out. He noticed that his voice was slightly deeper. He looked down at his underwear and pulled them down, freeing the hardening 9 inch monster. As he looked down he saw that his feet had definitely gotten bigger and he couldn't be 100% sure, but his calves looked a little harrier than they had the night before. Now, rock hard, he wrapped one larger hand around his cock and began pumping as he watched sweat drip down his glistening muscles. He reached his other hand up to massage his pecs and play with his nipples. It didn't take long until hot ropes of cum shot out of his cock all over the mirror. Andy fell backwards onto his bed, wondering if Jesse came that hard when he had the bigger cock.
Looking at the clothes around the room, Andy decided that none of them would fit him. He exited his bedroom completely naked, his pendulous cock dangling low between his massive thighs and made his way towards Jesse's closet. Walking by the bathroom, he could hear Jesse in the shower.
Andy searched for several minutes before pulling out a pair of clean underwear, a pair of grey jogger sweatpants, and a wife beater and setting them on Jesse's bed. Jesse had worked a summer job and had saved him his money to buy some nice sneakers, which Andy grabbed a pair of too. Just as he was about to get dressed, Jesse walked in to.
"What the fuck are you doing with my clothes?" Jesse asked his now not-so-little brother.
"None of mine fit me anymore," Andy answered. "Thanks by the way for trying to fight me last night." He lifted his arms into a double-bicep pose again, his massive cock still hanging out. "I really like being big."
Jesse knew he was supposed to be nice, but he couldn't help himself, "Just get out you fucking asshole!"
It only took a second or two, but the air between them seemed to stand still. Andy's body bulged slightly and he grew two inches taller, putting him right at 6 feet tall, just 4 inches shorter than his older brother Jesse.
"Thanks again," Andy said grabbing Jesse's clothes and walking out of the room.
Jesse still wasn't sure what to do, but he started to imagine having that rock hard 9-inch cock in his mouth.
