“Beginning phase five.”
Charlie, at this point desperate, grunted and yelled, "This!" He broke the pin and the two of them struggled for a time. Charlie surpassed Lee's size once again and soon attained nearly his maximum size, at about 285 pounds of muscle and fur.
Charlie knew he needed to end this now. He drew back his arm for a knockout punch, but Lee screamed, "Wait!" just in time.
"Yes?" said an annoyed Charlie.
“You need me. To stop the machine. It takes two people to press the buttons.”
Charlie remembered that that was true, and ending it was what he needed right now. “Alright, then stop it now,” he said solemnly.
Lee didn't reply. “It looks like you need a little convincing," Charlie said gruffly, connecting his fist into Lee's face.
"Stop!" Lee cried.
"Why?"
“Or I'll- I'll beat you up.”
Charlie was nonplussed but he decided to hear Lee out. “Each round I grow more and you shrink more. This is the last time you'll be bigger than me. Soon I'll tower over you and if I'm angry that's going to be a bad situation for you,” Lee threatened. Charlie knew he was right. This had to end now, and since intimidation wouldn't work, perhaps diplomacy would.
Charlie grunted as he lifted his massive form up off the ground, then extended his hand to help Lee up, who himself was not a lightweight. Charlie was hoping they could stop it now, but recalled that this round was only half over. The two of them stood face-to-face, with Charlie standing barely an inch taller, but the gap closed with every second that passed. Soon, Lee traded places with Charlie, and the size exchange wasn't slowing down. Charlie turned around in disgust, not wanting to admit what was happening.
He didn't see Lee continuing to grow, now high on growth of his own. When the round was over, Charlie turned around and was shocked to see how huge Lee was; he was far bigger than Charlie had reached at any point. Charlie, on the other hand, was back to his normal size, though without any clothes. He had hair covering his entire front and a good deal of his back, however, which at least made him appear slightly bigger, but he knew exactly how big he was.
Looking at Lee, he couldn't help but be faintly impressed, although this was tempered by his own sorrow. Lee was six inches taller than he was, with proportions that could normally only be achieved with Photoshop. Charlie couldn't really fathom how heavy he was, but if they had measured, they would have found that Lee was rounding out at about 350 pounds of solid, round, muscle. Lee didn't even seem too distracted by the fact that his cock was stimulating itself by rubbing against the cleavage of his pecs.
Charlie was disgusted with the situation. “Alright, look, I'm back to my normal size. It's over. Can we push the buttons to stop this thing now?”
