Trying his best to hide his panic

Walking out in just a bathrobe, Josh was in the middle of asking something when he spotted Sara on the bed, fiddling with his phone. Immediately getting wide-eyed, he stopped mid-sentence and felt a brief surge of panic course through him. "Um... Sara? What are you doing?"

Looking up past the phone, Sara fumbled with the app, closing it quickly. "Oh, I was just double checking the restaurant's address." She lied, reopening Google Maps. "Ashley wasn't specific enough when she gave it to me."

Giving his girlfriend a side look, he dropped his towel as he made his way towards his dresser. "Alright. Well, will you get dressed then? I'd like to get there before traffic."

Glancing down at herself, Sara almost seemed shocked to notice she was still naked. Discarding his phone, she jumped off from the bed and made her way towards her closet, Josh eyeing her as she ran by. His eyes were glued to her shaved pussy. While he long since stopped asking for it, he secretly wanted Sara to grow out her bush. Since the two of them rarely used her pussy anyway, he always wondered why she bothered to keep shaving it.

He shrugged, briefly bringing his attention back to his phone. He unlocked it, and confirmed Sara's words by noting that Google Maps had indeed been opened and the restaurant's address had been searched. He exhaled, his panic leaving him. One quick scan over the rules of the world app showed him that Sara hadn't changed anything, and he threw his phone back onto the bed, his new intent on finding an outfit for their date.

Later that night, Josh was cuddled up in bed next to Sara, unable to sleep. His thought kept going back to the app he'd discovered today and while he hadn't changed anything since their dinner date, Josh was unable to get the consequences of his change out of his mind.

The positives were obvious - anal sex was everything he'd ever wanted. With his one minute refractory period and Sara's new libido, the two of them had fucked twice more after dinner before collapsing from exhaustion. The pleasure he got from finally pounding Sara's tight, puckered hole had been worth staying with her until now.

He didn't regret the change. For as long as he could remember, sex had been as struggle; for everyone. He, his friends, and he assumed most of the male population just weren't interested in vaginal sex. While he knew there existed a fetish for it, it was rather common for a couple's sex life to rarely extend beyond mutual masturbation, handjobs, or oral. Sure, some would partake in anal sex but if the girl wasn't interested, like Sara had been, then odds are the couple wasn't fucking because it was a given the man wasn't interested in her pussy.

By making anal sex a girl's preferred form a sex, Josh was convinced he'd done the world a grand service.

Still, he couldn't help but admit to himself that the change had been rash. Whether he wanted to admit it or not, regular vaginal sex was still important; after all, it was human's sole way of reproducing. Sure, he'd made it so that women needed to take supplements to eventually get pregnant as a way to avoid any accidental pregnancies, however unlikely those are to occur, but one could never be too careful.

Yet, by having women prefer anal, coupled with men's obvious disinterest in vaginal, he could have just as easily doomed the human populace by having no one really want to reproduce. Or at least, not wanting to commit to the act. Josh wanted kids one day, but the idea of fucking a girl's pussy to do it made him shiver.

Unable to settle his thoughts on the matter, he reached for his phone and opened the app, taking a quick glance at Sara to confirm that she was sound asleep. Hoping to make things right, he started typing.
