Adam continued to stroke his dick as he watched it continue its growth. He kept looking at the door, wondering what Mario's reaction would be when he saw the transformation. Adam moved toward the closet where there was a large mirror so he could see his better for himself his changing body.
"Ho yeah, I look awesome!", he exclaimed at the sight. He was amazed to see how big his muscles had become on his enlarged body. He had to have gained almost a foot in height in the elapsed time. Adam still had his pants on for the most part, having only opened them to let his massive member out. He decide to lose his jeans completely.
As he bent over to push his pants to the floor, he saw his cock up close near his face. He paused and thought for a second as he kicked his pants away with his feet before he finally grab his dick and moved it toward his mouth. He had fantasized in the past about being able to suck himself off, and now was thrilled to actually to be able to do it. He pushed his head forward as far down as it could reach over the top of his dick. WIth one hand he stroked the remaining shaft while the other shaft tugged and played with his large balls.
The feeling was amazing both in having his hot cock in his mouth as well as his tongue moving up, down, and around the top of his dick. He was lost in bliss for a while enjoying the feeling of touching himself this new way.
As Adam approached climax, he felt the pressure in his balls start to build up and realized that he had to decide now if he was willing to actually cum into his own mouth or if he would back off and just let his load shoot freely. The pressure was increasing! "I'm gonna cum," he thought. "Gotta choose now!"
