The tingling continued as the sensation traveled outward from his balls to the rest of his body. Suddenly, Guy ached all over.
"Holy shit," he said. "What's going on?"
His question was soon answered as Guy looked down at his hands. They were--he couldn't believe it--bigger. Guy began to moan as the pain turned to incredible pleasure. His feet responded next, becoming elephant-sized, followed by his legs, which ballooned outward with muscle and size, making Guy taller and taller, forcing him to sit down.
"Fucking unreal," Guy muttered to himself. "I'm actually growing massive."
And massive he became, as his torso was almost done expanding, making him a whopping fifteen feet tall. His head throbbed with pleasure and pain as it swelled larger and larger, his brain growing to accommodate, making him the smartest person alive. Finally, his arms responded and made their way to giant size as well, causing muscles to strengthen and grow, making Guy the strongest man alive.
Guy roared with pleasure as his massive cock began to throb. With each breath he took, Guy could feel the massive member swell larger and larger and larger, until it was five feet in length, compared to his twenty-foot tall body. He was, in fact, the biggest man alive.
"Oh man," Guy said. "I've gotta call someone. This is incredible."
