Herman Keller, a man with a penchant for chicks with dicks

Your hand shakes as you reach to write in the book. You know what you must do.

Old rule: In stead of vaginas, women have penises, ranging in size between six and twenty inches long, and testicles that grow larger as they age.

The world twitches, and you look around to see what you have done. The woman standing in line for her coffee changes her posture, and you watch her knee-length dick sway beneath her skirt. It was thick like a soda can, with a swell in the middle, and the head flared broadly. And she was wearing a striped stocking over it that matched the two she wore on her legs. You looked around the coffee shop, and saw that all of the women were wearing garments over their new (or old, you suppose) penises.
All of the women with the largest dicks wore sleeves or socks over them. One plump goth chick wore hers mostly bare, jutting from her jean shorts, nestled between her thighs. Only the head had a denim cap over it, cinched with a drawstring. Her shorts bulged with her balls.
The women with smaller cocks mostly wore theirs tucked into pants. You saw a woman in her thirties get up from her seat and walk towards the bathroom. Along with her pink crop top and hoodie, she wore grey sweatpants with a melon-sized round bulge bouncing in her crotch. Was she wearing some kind of push-up panties? You spy another woman, this one wearing khaki slacks. Her button fly was opened all the way, revealing a proudly bulging package sitting in a red low-cut pouch, with the shaft of her dick cresting the top like some sort of penis-cleavage.
Then you notice how many women's dicks you can't see. Maybe a third of the women were wearing designer fanny-packs in front of their crotches. One woman, a late-twenties latina sitting at a table, opened her bag between her legs. Curled up inside was her long dick, and nestled among it was her makeup, wallet, and various bottles. She uncurled her dick, pulled its sock down to its head, and began applying a lotion to it from one of the bottles. You take a sneaky look at the bottle, trying to not look like you're staring, and you see it's called "cock softener". What was that, a skin cream?
You come to a realization. You can just look on your phone, and learn all about the new world. You fire up your phone look up Penis (Human Female) on Wikipedia. All sorts of interesting details come to light. The urethra of the female penis is like a vagina, a sensitive erogenous zone, and where men insert their penises to have sex. Apparently female penises drool like crazy. Though you can't see most of them beneath their sleeves and other garments, these women all were likely wearing some kind of precum drool stopper, be it an absorbent pad or urethra tampon or, for more hyperactive droolers, a condom or plug. And you didn't just end the human race, because women still give birth, just from out their dicks. Women have all sorts of products to apply to their penises, such as cock softener for halting erections (erections are damaging to their clothing, embarrassing in public, and considered unladylike), plumper for keeping them fat and juicy, a cum controller for stopping the constant flow, and a cum inducer for curing the debilitatingly painful backups that come from using cum-controller for too long, among other various cosmetics too numerous to count.
You look up from your phone and step aside to let a plump woman in her fifties squeeze past you. Her huge balls swing freely beneath her skirt, and you notice her cock head, wrapped in a lacy sleeve, peaking out of her tanned cleavage.

Your mind swims with the possibilities. Where to now?
