John considered his options as his eye level sunk. First he was looking at the other man's nose, and then his chin. As John's gaze reached the top of the other man's hairy chest, he relented. Pushing forwad, he threw what was left of his little body on the giant boner.
The pressure stopped, and the giant wrapped his legs around John. "Oh, that is much better," he rumbled. At first, John stroked the long shaft and licked the fist-sized head. The giant reached a hand down and flopped out orange-sized testicles on the toilet seat. John watched as the giant balls continued to grow, and he remembered at once that the laws of Toon Land could work to his advantage too.
With a gulp, John stuck his mouth down over the smooth skin of the tip of the giant's cock. He expected it to taste nasty or be disgusting, but the actual experience was surprisingly anticlimactic. Stuffing as much of the big dick in his mouth as he could, John then tried to stuff a little more. As he expected, he was successful.
Then a little more, and a little more... John inched his way down the long, thick shaft. Each time he thought he had taken as much as he could, he tried a little more and discovered that it fit too. The giant cock was shrinking to fit itself into his mouth, and would soon be just a memory of its former glory.
The giant started to grunt as John's nose finally reached the base of the cock. Taking his mouth off the now-small boner, John quickly stroked its remaining few inches. Leaning back, John could see the watermelon-sized balls were now shrinking too. The giant twitched as his balls deflated, to cantaloupes, then grapefruits, down to orange-sized and then lemon. Panting, John heard a familiar hissing start, and his furry giant began to shrink with every stroke.
