He decided to make the entire world population male for the fun of it and to see if it truly would change the world. He put in the settings he wanted such as dominant and submissive males where the submissives would look extremely feminine with long hair, slightly feminine facial features, large asses, breasts that would grow upon the submissive's first time being ducked by a dominant repeatedly or their first pregnancy, along with being able to produce milk and their assholes being self lubricating and extremely sensitive, causing extreme pleasure each time they were fucked by a dominant male, they would in general be no taller than 5'5, 5'7.
While Dominant males would have extremely large cocks, be very muscular, not too hairy but hairy enough to be manly, whereas submissives had no body Hair except for what was on their heads and Dominants would be a height of 6 feet at the shortest while the tallest could be 6'10, along with having increased sex drive and almost endless stamina.
Submissive's would be extremely fertile for a week or two each month, their cocks would be quite small but still noticeable and there would be no diseases or hunger as the only ones that needed to eat actual food were the Dominant's, the Submissive's would only be able to eat their master's cum or the cum of any other dominant. The animals would be the same as always as he only wanted to change the human population. There would also be plenty of sex toys that "vanished" waste if they were left in the submissive so the dominant could have the submissive look pregnant without actually being pregnant.
Submissive's could also only get pregnant if a dominant wished for them to be pregnant otherwise they would not get pregnant no matter how many times they were fucked. Submissives would also be able to hold the dominant's cum in them until a dominant emptied them. If a dominant wished to use the submissive as a drink dispenser they only needed to fill up the submissive with their desired drink and the submissive's body would adapt to produce that drink instead of waste and it was the same concept for a food dispenser they only needed to put a sex toy that would vanish waste on that part. A submissive could be fucked by a male animal if the dominant wished and would have that animal's children their body adapting to it. The body of a submissive would be extremely adaptable to anything and a person would know if they were Dominant or submissive upon reaching their 5th birthday. He didn't notice the button that said reality shift on/off or the one that said time limit Y/N before hitting submit.
Poor Jeff was in for a surprise and he wouldn't remember any differently to change it...
