Jeff and Sarah watched the TV, looking at the world they had created. Lowered life expectancy, terrible hygiene practices, and widespread medical problems; Jeff started to feel bad.
'We have to do something about this,' Jeff said, as he wet his diaper uncontrollably.
'But I like our diapers,' Sarah replied, feeling his wet crotch. They began to formulate a plan for how they could keep the diapers, but solve the rest of the problems.
After a while, and a few soiled diapers, Jeff and Sarah came up with a solution. First, they made it so that diapers literally grew on trees. Everyone would keep one of these trees in their garden, making diapers essentially free.
Secondly, to solve the hygiene problem, they would make it so humans would now shit warm chocolate ice cream, and their pee would be completely sterile. That way, there would no longer be any widespread hygiene issues.
Finally, they made every human's body adapted to wearing a diaper. No longer would anyone get rashes from their diapers, and baby powder sales would go to virtually nothing; people could wear their diapers all day long without any problem now.
As they hit apply, Sarah felt herself unloading her bowels into her diaper. However, there was no longer any strong smell, now there was simply the sticky feeling of chocolate ice cream on her ass. Jeff took off her diaper, and licked her clean, making her moan as she felt her boyfriend's tongue in her ass. He changed her, smacking her ass as he finished.
A few minutes later, Jeff filled his diaper too, spreading chocolate ice cream all over his waist. No longer needing to worry about hygiene, he simply left it there, savoring the feeling of his full diaper. He began to rub his tiny cock again, cumming within less than a minute.
He sat there, chocolate and cum in his diaper, as he considered what to do next.
