Karyn's wish altered brain and body was craving giving a blowjob. Jon's normal unaltered male mind was craving receiving a blowjob.
So naturally, when Karyn started grinning and pawing at Jon's pants to undo them, he didn't try to stop her!
Karyn worked Jon's member free from his underwear and she could see it was already starting to rise to attention. Karyn drooled a bit with her arousal and she licked her lips in anticipation. Of course Karyn's lips were now sex organs and were engorged a bit from her own arousal. Her licking them sent a shiver of sexual energy through her body, causing a slight moan to escape her lips.
Jon soon felt Karyn's hot wet mouth close around his erect cock. She began to work her mouth and tongue like a true pro, giving him hands down the best blowjob of his life! Karyn was enjoying things too, and load hums and moans of female arousal could be heard from her. Jon felt her mouth clench around his cock and he could see her body convulse as she had her first orally stimulated orgasm!
Karyn got into things even more and began to move her mouth back and forth over Jon's cock. She was literally FUCKING him with her mouth! Before long she had yet another powerful orgasm emanate from her mouth and through her body.
Jon was amazed that Karyn had already orgasmed TWICE before he had even shot his load. This was even more surprising because he knew he could not last long given Karyn'e EXPERT oral attention either! His wish had come true, women REALLY liked oral sex now!
After what only seemed like a minute or two Jon could feel his orgasm begin to build. Out of a habit he picked up from his last girlfriend, he warned Karyn he would be cumming soon, forgetting that in this world, women didn't care about guy's cumming in their mouth. Karyn never missed a beat, she just kept orally humping his penis with glee. Her feminine moans of sexual enjoyment were load albeit slightly muffled by the erect cock filling her mouth.
As Jon emptied his load into Karyn's eager mouth, she too had a third and final orgasm rock her body. Karyn happily licked her lips, enjoying the taste of the male semen filling her mouth.
As Jon and Karyn cuddled in post orgasmic bliss under the tree, Karyn was glowing in post coital pleasure even though she had never removed her clothes! Not once during the whole experience did she even think about the now sexually useless vagina that sat untouched and ignored inside her pants.
Both Jon and Karyn were still unaware that elsewhere in the world millions of vaginas were being ignored in much the same fashion. Please note that it was millions, and not billions because in this new reality the human population of the entire earth was only about 195 million!
Since women were always used to their sex organs being their mouths and men were used to women's sex organs BEING their mouths, the vast bulk of human male semen has ended up going harmlessly down the throats of human women.
Oddly, since women provided "full service" with their mouths, they rarely ever even got naked for sex now! Sure sometimes women took their tops off to free their breasts, but both men and women were usually more interested in getting down to BJ action. Breasts were a mere distraction.
Men didn't really get very turned on by naked female bodies anymore anyway, as the thing they REALLY wanted was right on the women's' faces! The vagina was something only used for peeing and reproduction. So unless the goal was reproduction, neither men nor women had any use for taking panties off during sex to reveal the smelly mostly ignored orifice hidden away beneath them.
In fact, the only time a woman usually even tolerates vaginal sex is if she is specifically trying to have a baby! While vaginal sex still felt fairly good for a man, fucking the sexually numb vagina of a bored unresponsive woman was nothing compared to the enthusiastic fucking she could give with her mouth! So, like women, men ALSO greatly preferred oral sex now! Naturally, men would usually only want vaginal sex if they wanted a baby too!
The side effect of a reduced population was that the world was a far more quiet and peaceful place. With little competition for now relatively abundant resources, mankind had not had nearly as many wars as in the old reality.
Also, women typically only got pregnant when they were in a relationship with a partner that also wanted to have a child. This made for far stronger families.
Jon didn't realize it at the time, but in a lot of ways the world was a better place because of his selfish wish...
