Losing the coin toss

As you close the rule book, your head full of the thoughts of fucking cat girls, the world around you changes. You watch as about half of the people in the coffee shop change. Some guys change into feminine flat-chested cat boys, and some girls change into cute cat girls. You smirk as one of the waitresses(now a catgirl) races around the shop taking orders as her tail follows after her. You have done it, cat girls are a thing now.

After watching for a few moments an interaction peaks your interest. A human customer, someone whose face you recognize from school, calls over one of the cat girl waitresses and speaks with her for a couple of seconds. You don't hear what he says but after a moment the cat girl nodes and goes down on her knees. Without another second thought she unzips his pants while he is sitting at the table and begins to give him a blowjob! You look around and realize that a few other sexual acts are being subtly performed throughout the coffee shop. You even see one of the cat boys sitting on the lap of a human male, who appears to be his owner, trying not to blush with the man's cock discreetly up the femboy's ass.

You turn to another cat girl waitress as she passes nearby, hoping to get in on the action: "Hey cutie, why don't you come over here?"

"In your dreams shrimp dick." She replies as she walks right past you.

In less than a second you realize two things: 1. You voice is suddenly very feminine. 2. this girl is not very nice.

For the first time sense you wrote the neko rule you look down at yourself. You are no longer wearing pants, instead a pink skirt now sits around your waist. In a panic you pull at the skirt just enough to see that not only has your dick shrunk from 7 inches to 3.5 inches, but also you are now wearing panties. You raise your hand to your head and feel longer hair than what you had before. In an even larger panic you slide off your seat and begin making your way to the bathroom, the tables and chairs and people looking much taller than they did a moment ago. You push open the bathroom door and you make eye contact with a short, brown haired feminine neko with a pink skirt. A second passes and your brain clicks. This was a mirror. You are now a cat boy. One of your hands reaches up and feels the large cat ears on your head and another reaches behind your back to feel your tail. This confirms it, your body had significantly changed.

As you gaze into the mirror you begin to realize that you are now very cute.

"How...how could this be?"

You remember the rule you wrote earlier. When you said half the population you weren't expecting to be in that half. It must be that even the rule writer is not immune from the rules. Well then, if the rule book caused your body to change like this, then the rule book can change you back.

With this solution in mind you leave the bathroom and begin heading back to your seat, upon arrival you pick up your pencil and begin thinking of a way to reverse only your change. Suddenly without warning the rule book is ripped from your hands.

"Hey-!" You try to say but you are interrupted by a familiar voice.

"Hey faggot. I was just stopping by to return your purse but then I find you're writing a diary."

You whirl around in your seat and to your horror you see Jeff, your bully, standing about a head and a half taller than you holding the rule book.

"Give me that!" You say and try and grab it out of his hand but he raises it easily just out of reach.

"Woah, slow down there lil'guy." Jeff says to you. "Keep your feet on the floor or else your skirt will fly up and everyone will see your two-incher."

"Screw you Jeff!" You say trying to grab it again to no success. "And it's three point five inches, not two!"

Some people nearby turn to look and you hear some girls giggle as you realize Jeff baited you into admitting your actual cock size. Your face turns deep red and Jeff smiles.

"Tell you what." Jeff says putting a hand on your shoulder. "How about you do me a favor and you can have your sissy diary back."
