All of a sudden the bathroom grew larger. There was a sink and toilet on either side of the shower/bath that Jon shared with his sister Zoe. Jon turned his head and through the foggy glass he could tell his sister was sitting on the commode on the other side of the shower. The shower was quite large, clearly intending on multiple people being able to either stand or submerse themselves in the recessed bath section. There were also areas where one could sit and shelves for many products compared to what Zoe had been using before.
Jon didn't want to let Zoe know what he was doing, so he left and entered his room through the door on his side of the shower. Jon's room all at once looked smaller, but surprisingly he had more expensive things. There was a nice TV on one wall that stretched from end to end and his clothes looked nicer too.
"I wish to know the population of Earth now." Jon wished while still holding the rock. In his mind and heart, he knew in response that the population at the end of the day would be 23 billion people. It took time for magic to travel and change the rest of the world, with the natural limit of the stone's power being a mile. In order for the wish to work, the stone made the spell spreadable, from person to person, from contact with water or air just like a contagion. Once the people and society were changed the history and everything else affected by humans would change with them.
"Based on that, the average amount of girls born now is quadruplets."
Jon smiled to himself, wondering what else has changed about society.
"At least we don't have to worry about population decline for a little while longer." Jon thought to himself. "The problem is the third and fourth world where there's high birth rates." Jon frowned. "Now I'm stuck on population control when I simply wanted to wish I had multiple girlfriends."
Jon realized he was vocalizing his inner thoughts and ended up making a new wish on the stone. It flashed and he knew he had a girlfriend, but would it be someone he knew?
