Finally Jon shrugged his shoulders and said, "I give up, I can't see anything different about me."
Karyn walked towards him with a lustful stare in her eye. He turned to face her, his penis and testicles swinging wildly as he did so. If he wasn't so used to the size of them after all this time, they probably would've thrown him off-balance.
"Jonny," Karyn half-asked, half-gasped, as her horniness was now affecting her speech, "are you sure you don't see anything wrong?"
Karyn placed one hand on the shaft of his cock and stroked it teasingly, like she always did. Jon didn't mind people touching it anymore, hell his equipment was so big he could wear anything to cover it anyway. His shaft, which was always at least semi-erect, began to stiffen with his friend's experienced touch.
"No, I'm totally normal," Jon replied as the head of his penis rose past the height of his shoulders. He grinned and added, "And totally exceptional in specific area as usual, of course."
"Hehe, very much so," Karyn giggled and hugged his cock. It was almost as thick as his torso when erect, so to Karyn it was like hugging another person, well almost. Jon smiled and moved over to the bed. He sat down, but not before carefully cradling each of his basketball-sized testicles in his arms first - he'd made that mistake too many times before! Karyn followed and sat him, at least one hand on his dick at all times.
"Well, is it my turn with the wishing rock again?" Jon asked.
"Oooh, well," Karyn begged as she caressed one of Jon's balls, "couldn't we... have a little fun first? On our own, without the rock?"
