Chapter 3
What rules does she make?
Enjoyable ones
Alice smiled, there were so many good things she could do with this. Her mind kept running over all the possibilities. The first thing to do of course, was to change herself from a freak into something known and accepted, even if uncommon.
Old Rule: Futanaris are extremely rare, but known and documented and part of society.
Hmmmm, she thought, what if the previous owner wants the book back? Or if they died or erased themselves through a rule change?
New Rule: This book is the property of Alice Smith, no one else can use it or take it from her.
Old Rule: No one notices or thinks it's odd when Alice reads or writes in the book.
Old Rule: Alice Smith cannot die, get sick, or be held against her will. She cannot accidentally or purposely erase herself through a rule change.
Old Rule: Alice Smith can undo any rule by simply wishing for it to be removed from the book three times, thinking or speaking.
There, that pretty much covers all the things I can think of going wrong. Now, what can I do for fun?
Old Rule: Futanaris can always get hard and cum.
Old Rule: Touching yourself and masturbating in public is completely normal.
Now, let's see about adding some cum to my coffee. Alice reached down and resumed stroking her shaft. Hmmmm, I could use some lube.
Old Rule: Futanari cocks lubricate themselves.
Immediately her cock started getting slick with natural lube. It felt like her vaginal lube. She raised her slick fingers to her nose, Smells like my vaginal lube. She licked it, Even tastes like my vaginal lube.
Alice went back to stroking. It sure felt nice, she watched a couple of the women across the way enjoy their coffee. They weren't doing anything expressly sexual, but they both had pretty nice bodies, and they were turning her on. Then one of them reached down and started touching her pussy. The woman slipped one finger inside herself, and then a second. She pushed her chair back and brought her second hand down to play with her clit, while her other hand kept pumping away inside her.
That was all the stimulation that Alice needed to reach orgasm and shoot a big load of hot cum into her coffee. Even after coming she didn't let up, and her cock didn't soften at all. She kept stroking until she built to another orgasm, watching the woman at the other table masturbate, she bit her lip to keep from moaning, and then shot another big load into her cup.
She took a big gulp of coffee, and made a face.
Old Rule: Futanari cum tastes amazing.
After the next drink she smiled, That's better. Now it's time to get serious about making some changes.
New Rule: If Alice Smith asks someone to do anything with "pretty please" then that person will happily do it.
Now to give this a real test. "Excuse me," She waved to the barista.
"Yes?" the pretty redhead walked over and pinched her nipple, to which Alice responded in kind.
"Could you take me to the backroom with you and answer a few questions for me, pretty please?"
"Of course," the barista smiled happily, "follow me."
Alice stood up and followed her back to the backroom, taking the book with her. I'll have to write a rule that the book always comes with me, she thought to herself.
The barista closed the door behind her, "You had some questions you wanted to ask me?
"Yes. What's your name?"
"Amanda McDavid."
"Tell me, Amanda, what would you say your best feature is?"
"Oh, my hair of course."
"What would you change about yourself if you could?"
"Oh, I don't know. I'm pretty happy with myself."
Alice glared, "Oh there must be something, pretty please?"
"Well, I wish I had bigger breasts. You know all the guys love women with big breasts and butts, and I don't have either."
"Would you like big breasts and a big butt?" Alice grinned.
"Of course! But I can't really afford that on a barista's salary."
Alice smirked, then took out the book, "I'm going to do something nice for you."
New Rule: Amanda McDavid has a pair of perfect J cup natural breasts that have a perfect teardrop shape and don't sag at all. They never hurt her back or get in her way at all, and she gets super turned on by having other people touch them. She also has a big firm, bouncy, bubble butt that she loves being touched.
Old Rule: Amanda McDavid loves futanaris and is a size queen.
She smirked. Then added:
Old Rule: cocks range in size from 3 inches long to 18 inches long. The average remains the same, and extremely long thick cocks are very rare.
New Rule: Alice Smith has a 12-inch long cock that's 3 inches in diameter, and fits amazing in any hole that she puts it in and brings great pleasure to anyone who sucks, touches, or fucks it with no lasting pain or damage. She also has huge balls that give her huge messy cumtastic orgasms.
She waited, then watched with glee as her cock and balls swelled in size. She couldn't help but stroke her cock again as Amanda's breasts and butt began to grow from their boring size to their fantastic new size.
"What the hell is happening to you?" Amanda asked nervously.
"You should see what's happening to you," Alice grinned.
Amanda stared at her tits as they continued to grow, getting bigger and rounder with every passing moment. When they finally stopped growing she touched them hesitantly, "They're so big and soft, but not droopy," she murmured. "And they're so sensitive." She pinched her nipple and let out a sexy little whimper. "Oh, yes."
"What about your butt?" Alice could barely contain herself. "Let me touch it."
"Of course," Amanda said, eyeing Alice's cock greedily.
Alice gave her butt a big grab, her hands sank deep into the soft giggly flesh. She pulled Amanda forward, letting the redhead's huge new breasts smoother her own modest B cup, and kissed her deeply. Her cock throbbed her between them, pressed up against Amanda's stomach. Amanda responded to the kiss with fervor, while pushing her hands down to Alice's engorged cock.
"It's so huge," Amanda gasped, breaking away from the kiss, "and your balls," she cupped Alice's huge package.
"Suck it," Alice ordered.
Amanda dropped to her knees and wrapped her huge tits around Alice's cock. "That's not what I–ugggghhhh," Alice was cut short as Amanda slurped the head and bit of shaft that stuck through her enormous cleavage. She worked the cock with skill from both her mouth and tongue while using her tits to slide up and down the sides of the shaft. Alice felt her balls swell towards orgasm. Amanda must have sensed it too because she pushed the cock out of her mouth and between her tits, taking blast after blast between her breasts.
"That was intense," Alice moaned.
But before she could do anything else her cock was sliding up and down between Amanda's now generously lubricated tits.
"Doesn't it feel sooo good?" Amanda moaned. "I'm all wet just from your cock between my tits. Won't you cum in them again? I'd really love for them to be covered in your hot white cum." It was barely anything, but Alice couldn't take it. Another huge orgasm burst from her cock, spraying rope after rope of hot white cum all over Amanda's breasts.
"I want your pussy, now."
Amanda turned around and pushed her enormous rear end up against Alice's cock, letting the thick meat slide between her enormous butt cheeks. "Please, please, give me your huge cock, right now."
Alice reached down and pushed her cock up against Amanda's pussy lips, then shoved it in, all twelve inches at once. It was heavenly, warm and soaking wet and so, so tight. She started to move in and out, trying to keep herself from going full blast right away. But she couldn't: she needed that pussy. She needed to fill that no longer just cute, but now smoking hot barista with as much cum as she could hold. Her hands grabbed onto the woman's sides, and she lost control, smashing her hips against the big soft pillowy butt; thrusting as hard as she could over and over again, pushing herself toward and orgasm.
It was so good. So good. Amanda's butt was amazing, her pussy was amazing. So amazing that she was going to cum. Her pace quickened as she felt her third orgasm build.
"Oh yes, cum inside me, fill me up!" Amanda yelled.
Alice couldn't control herself, hot white cum exploded in burst after burst until it was leaking out around her cock. But she didn't want to stop, she wanted to cum again. She kept up the pace, Amanda's moans driving her need and desire. She built toward a fourth orgasm, and she could tell Amanda was building to her own orgasm. Alice wanted to come with the woman, to feel their orgasms happen together. She kept going, holding out, trying not to cum until the hot pleasure washed her entire body and sent her spiraling out of control.
It was heaven, Amanda's muscles clinching down around her as the first spasm of her own orgasm rocked her. Her hot cum was drawn deeper into the convulsing vagina than her cock could have ever pushed it by itself.
But Alice still wasn't satisfied, she wanted to cum again. So she kept pumping into Amanda's sloppy pussy. It was so slick now from Amanda's juices and her own cum that she just slid in and out effortlessly.
"Ohhh god, are you going to cum in me again?" Amanda moaned. "Yes, it feels soooo good. Fuck me and make me come again!"
Alice didn't have any control of herself anymore, she just wanted to keep cumming in the hot redhead's pussy. She kept thrusting and moaning, while the woman under her kept moaning and begging to cum. Alice came once, twice, and three times before Amanda's moans increased in tempo.
"I'm going to cum again, please fill my pussy up with lots of cum at the same time!" Amanda nearly shouted, her voice husky. Alice thrust twice more before Amanda grunted, "Cuummmmmmiiiinnggg!!!"
Alice exploded with the biggest orgasm yet, her cum forcing its way around her dick on the first shot, and continued to **** its way out of Amanda's glutted pussy on all twenty-some shots that she unloaded.
Amanda slid off of Alice's cock and into the puddle of cum, where she lay happily basking in the afterglow of her orgasm.
"That was incredible. You can fuck me like that anytime. I'll give you my number and my address, drop by anytime," she smiled.
Alice let her put the info in her phone. "I will definitely take you up on that. You should probably clean yourself up before you go back to work."
"Uh, huh," Amanda smiled.
I hope she's okay, Alice thought to herself as she walked back out into the coffee shop. She felt awesome, and she had big plans for this incredible book.
Where does she go next?
