Bigger is better, right? And the changed shape is probably just temporary swelling. Has to be.

James couldn't look away from his beast-like cock. With trembling hands, he let his fingers run over the incredibly sensitive skin, prompting a few wild twitches that sent the last vestiges of cum spurting from the pointy tip. It was huge! Ten, maybe fifteen inches long, and at least five inches around, twice that at the knot! A slightly twitchy smile spread on his face - this was awesome! The pills really worked, albeit with a few side effects. And this weird swelling that made his cock look so inhuman would go away. For sure. And even if not, who could resist a dick this huge?

While James still tried to wrap his head around the changes to his body, his monstrous rod began deflating, shrinking, pulling back into his fur-covered foreskin until it had formed an about fist-sized, fuzzy bulge against James' lower belly and crotch. Only now did he notice that his balls matched his sheath, covered in short, red-brown fur. But who cared about increased pubic hair if his dick was now three times as big.

Seeing the mess he had made on his desk, James decided to clean up, wiping off the lacquered wood with some tissues, absentmindedly scratching his stomach and lower ribs. Pretty damn itchy... was he allergic to something? Better keep an eye on that. But for now, James was done cleaning and, he realized, incredibly hungry. Pulling up his pants, he smiled at the way the crotch now strained to contain his package, threw away the cum-soaked wipes and went to the kitchen to get something to eat.
