Josh had a very strange fantasy. He fantasized about a world where women would go into heat. He thought it was amazing that female animals went into heat and thought that it should happen to humans as well. He began to write that heat would be a part of the female puberty. He made it so every 6 months a women would go into heat. Their vagina would become red and puffed out. They would also be very aroused and wet. Women would also have a smell when they where in heat and males would then become hard due to the smell. This would end after 1 to 2 weeks or if the women became pregnant. Women could still get aroused and pregnant when not in heat but when in heat the chances of getting pregnant where higher. Josh really wanted to see the effects first hand so he decided to set time back to when he was a freshmen in high school so he could witness a lot of heats. He made it so that if women where in heat at the school they would still be expected to attend classes and control themselves, but girls who couldn't stand it would either skip or end up pregnant. He also set it that their where body products that would help mask the heat smell but not all women would be prepared for it. He smiled as he finished writing in his details as the world shifted around him.
