"Oh, oh shit! This feels... awesome!"
At this point, the growth sped up immensely. Before the chocolate, Justin was already quite above average with nine and a half inches, which is why he'd never actually had sex, but plenty of blowjobs and handies. None of the girls he knew could take it, but that didn't mean they couldn't worship it. Now, because of the chocolate, it was over fourteen inches, and still growing, and the head was bigger than the apple he'd had at lunch!
"I am soooo okay with this," Justin said to himself.
He tore off his shirt (not literally, I mean he took it off), and started rubbing his sexy six-pack and substantial pecs that's were starting to strain a lot of the shirts he owned. That working out he'd been doing the past few months, at his manager's recommendation, was showing impressive results. But that was nothing compared to what happened next.
He continued to stroke himself, his cock continuing to grow past sixteen inches, with magnificent nads, the size of oranges, whereas before they had been mere eggs. Suddenly, his cock got... farther away? And so did the floor! A pair of abs, followed by a second pair, were growing right beneath his original ones, making him at least four inches taller. This ten-pack was unlike anything he'd ever seen, and sent him right over the edge.
He came. Hard. Must have been a liter, at least! All over his bed and the wall behind it, but that didn't concern him. He spent three more hours, just jerkin' his gherkin, and each time, it grew a little bit longer.
"Thank god mom is gone all week, I'll need at least a week to get used to this," he thought, then smiled devilishly.
At this point in the afternoon, his cock was twenty inches hard, and twelve flaccid, and he couldn't fit it, along with his bollocks, into a single pair of trousers he owned. It wouldn't have mattered anyway, his legs were six inches longer to accomodate all his new calf and quad muscle, and along with his new abs, he was nearly a foot taller than before. Then he remembered...
