Adrian gawked at his huge balls. Even though his cock had grown to be 6 inches long soft, it was dwarfed by his two grape-fruit sized balls, which were now churning as they produced more sperm. Suddenly, Adrian's cock began to rise again, and Adrian could feel the oncoming shot. He braced himself, and...
"AAAAAAAAAAAAAA" Adrian yelled as his cock shot cum across the room. The release also triggered a huge burst of testosterone, causing several changes to Adrian almost instantaneously. Adrian shot up a foot, to a massive height of 6'7". His muscles swelled up, becoming strong and bulky. Adrian's cock grew another 2 inches longer, and Adrian's balls, already huge, swelled up even more to go with it.
Adrian recollected his senses. He now looked ridiculous. His face, although slightly more angular, was still fairly childish, but it rested upon a body that could not be described as anything other than "pure masculinity". Wide muscular shoulders framed a tapered V of muscle. A huge python of a cock and monster balls rested between his legs. His feet had grown over 10 sizes, from their previous Size 7 to a Size 19.
Adrian started to feel it again...
