Colin smiled as his minor acne cleared up before his eyes (he was now standing before a full-length mirror that hadn't been there a minute ago) He had programmed the changes he had made to himself to take place slowly, so he could savor every moment.
Colin's eyes danced with excitement as his face assumed a more pleasing shape, his new shoulder-length shiny brown hair falling past his now-blue eyes in a way that would make any teen heartthrob turn emerald green with envy. His tee-shirt shimmered, becoming a white muscle-shirt as his shoulders broadened and his muscles bulged, his new eight-pack showing clearly through the thin fabric. His cargo pants became Levis so baggy they nearly fell off his hips. In fact, they drooped low enough for a close observer to see the beginnings of his thickening pubic hair. The pants baggyness hid the growth of his leg muscles, but couldn't disguise the growing bulge in his groin.
As the changes ground to a halt, Colin glanced once more into the mirror. It was now occupied by the handsomest man he'd ever seen, a young bodybuilder of about eighteen. If Colin hadn't seen himself change, he would never have believed this young stud could be him. Just looking a his new body aroused him, which was now a serious matter. His pants looked about ready to split as his cock tried to thicken within their tight confines.
Whipping off his pants and (brand-new) thong, Colin began to slowly stroke his huge pole. It pulsed in his hands, lengthening to massive proportions as he aroused himself. He turned his head down, and gently began to suck on the head of his own cock. Almost immediately, his near-grapefruit sized balls began to churn, and as the most intense orgasm of his life hit, his own hot, salty cum sprayed into his mouth like water from a firehose. He desperately swallowed, trying to take all of his juice, but his mouth overflowed, cum dripping down his shaft.
After a minute or two, the flow slowed, and Colin pulled his sticky lips off of his cock, licking to make sure he had gotten as much as he could.
He had been right. This WAS a lot of fun. And Colin knew just who he wanted to join him...
