Karyn continued to rub the stone in her hands as she said to Jon, "Well Jon, I must say I have had a lot of really great orgasms from your wish, I gave them all to myself of course but they were still good, I have to admit that. You know, I've been thinking the orgasms I get from masturbating myself now are so good that I don't see why women even need men to have penises at all now. I mean, they don't give us Mastolin and they can't really compete sexually with our skilled fingers anymore, can they? And as far as reproduction goes male sperm only has to get inside us, right? It really doesn't matter how. I'm sure even a turkey baster could fill in for a dick just fine. Ooh, there's also all these kinky female sex toy shops around now, I can't wait to see what's in those. I bet what's in there could really make your little dick obsolete in more ways than one, huh Jon?"
Jon's eyes were pleading but the wish kept him silent.
Karyn held the rock and said, "I wish all men's penises were half the size they are now."
Jon looked down and saw his cock shrink in size until it was literally half the length and girth it had been before. Jon's dick had only been about 5 or 6 inches erect before, and now that it was limp and reduced by half it looked tiny and pathetic. Even if Jon could get an erection at the moment it would be less than three inches long!
Karyn giggled at seeing Jon's manhood shrink. "Oooh look at your cute little willy now Jonny! Not going to be pleasing the ladies with that are you?"
Jon tried to respond but found he still couldn't speak!
Karyn saw Jon's expression and said, "What, you still can't talk? Well, that's because I'm not done wishing Jon. I wish that men's penises were half the size they are currently."
The stone glowed and Jon saw his penis fall by half yet again. It now was barely visible in the tangle of his own pubic hair.
Karyn laughed out loud at the sight of the tiny dick on Jon's crotch. "Wow Johnny, you guys aren't such studs now. Just think, all the other men out there have little tiny dicks too, just like yours. Just think of that tiny little penis dipping into the big wet vagina of a woman and, well, not much would happen really!"
Jon fought to say something, to do something, but he knew full well Karyn wasn't done yet.
Karyn walked up to Jon and put her groin right up to his. "Look at this Jon, my clit is bigger than your dick now! How does it feel to know that women are better 'hung' than men now?"
Jon looked down and saw that indeed the clitoris sticking out from the cleft of Karyn's pussy was literally larger than his penis.
Then came Karyn's final wish, the one she had been alluding to since she got the stone from him. Looking right at Jon with the stone in hand she said, "Well Jon, you wanted to see women masturbate huh? Well, that's all you or any other man is going to get from now on! I wish that men had no penises at all, just a urethra opening above their balls to pee and cum out of. I wish that men would only orgasm from seeing a woman orgasm."
The stone glowed and Jon saw his penis disappear altogether. There really was nothing in his crotch now except for his balls and a tiny slit right above them. Jon knew that all men were dickless now, forever!
