Clay said, "Let's start by giving you a little relief in the sex department." Adam looked up speechlessly, afraid of what Clay would say next. Clay continued, "I wish you would have yourself an incredible, full-body orgasm. In fact, don't stop until you are simply covered in your own cum."
Adam's eyes widened, and then rolled up in his head as he started to shake. Clay gave Adam's giant balls an extra little squeeze as they tightened and began unloading their magical payload.
With Adam temporarily occupied, Clay turned his attention back to Mario, who had gone over to a pencil that was far too big for him to even THINK about using. "What about you?" Clay asked leaning over, his breath almost flattening Mario. "I wish you were at least three feet tall so we could talk," Clay said, but nothing happened. Clay straightened up and looked down at the tiny man. So much for that; the wishes only worked on Adam.
Turning back to his newfound playmate, Clay saw Adam had done a good job of getting cum all over his upper body, but his legs were clean. Adam's eyes were open but wild, his teeth chattering, and Clay wondered what it must be like to drown in pleasure. Clay helped Adam's body shakily stand up, the little dick dutifully pumping away, about once a second. Clay wondered how long it would go on, but after everything else he'd seen today, suspected that forever might not be too long.
Once on his feet, the fluids quickly ran down Adam's body and soon he was covered, just as the wish had specified. Once satisfied, Adam's dick quit pulsing and started to go soft immediately. He collapsed with a sigh on the floor, and Clay went to rummage up a towel to clean up the mess. By the time Clay came back, Adam was not even barely recovered, his enormous balls swollen in his lap, but Clay could see that Adam's body had shrunk smartly, to less than 5 feet now.
