Dark Obsessions and Forbidden Desires

As I lay on my bed, waiting for sleep to descend upon me, I was immersed in thoughts of my step-sister. My bitch of a step-sister, Evelyn, who, at 21, was three years my senior, was asleep in her room. And frankly speaking, I don’t even know why my parents adopted that dumb bimbo.
No matter how much I hated her, I often did this, fantasizing about her. She was incredibly hot, and in the freedom of my imagination I did all kinds of unspeakable things to her. Reality was a different story, though. We were the usual bickering siblings who irritated each other.
As I lay there in peace, I thought about her full tits, which always seemed to press against her t-shirt. I thought about her round spank able ass which filled out her jeans so perfectly. She had a beautiful mane of dark brown hair which ended at her shoulders neatly. She had a sumptuous mouth, and I’ve always wondered how it would feel to have my penis move in and out of her pretty lips...
My eyes opened – it was already morning. I smiled – what a wonderful dream it was! There was also a sweet smell in the air – I wonder where that came from. Now, wait a second...
Why the fuck was my ceiling pink?
I sat up instantly. I was in Evelyn’s room! Oh god! Had I done something last night??
I looked around, she was no where to be seen. It was then that my eyes rested on the full-length mirror on my right....
Oh good god. Oh dear, dear god.
I didn’t know how to digest this – how could this happen? Is this even fucking true? I got up and walked towards the mirror...
I felt my face.... Evelyn’s face, that is. That’s right, I was Evelyn. As in, I was in her body. My heart was almost beating right out of its ribs as I saw Evelyn's – sorry, my – frame in the mirror. I was dressed in a pinkish night dress which ended just below my waist. I felt the smooth skin on my tummy, and I felt the massive rise of my breasts. I moved my hands down my smooth hair. I turned around and caressed my cute bubble butt in the mirror.
This was amazing, and scary. What did this mean? Was Evelyn in my body now?
All this was so overwhelming I walked out of my room just to see if the rest of the world was normal.
I walked down the staircase and into the dining hall; my parents were having breakfast quite normally. Dad looked at my face and asked, “Is something the matter, sweetheart?”
Sweetheart? Yuck!
“Umm, no Dad, not at all.”
Her voice felt so fucking weird! I got up and walked back to my room.
I looked at myself in the mirror.
“I’m Evelyn”, I said to myself, and her voice just crept me out. But this could be fun, right?
“I like cock in my ass”, I said before breaking into a giggle. Then I stopped. God, not even my laugh sounded right anymore.
Without even having a bath, I changed into a t-shirt and skirt and hopped downstairs for breakfast.
Dad was just getting ready to leave for office. My mom was still in the kitchen. There was still no sign of me, I mean, my little brother. I sat down at the table, and asked mom, “Where’s Jake?”
“At school.”
“Oh yeah”, I replied. I was feeling a little nervous, not knowing whether Evelyn was in my body or not. I also thought about how she was coping with it. And, most importantly, how awkward would it be when we met!
Breakfast went normally. I was preoccupied with all things I could do. Oh, this was the perfect chance to take revenge, to vent out all my hatred for my step-sister, and also have a little fun myself.
One thing I knew for sure was that once we changed back, Evelyn was going to be sorry for her entire life.
It was 9 AM. Mom had also left for work. I was alone in the house. I ran up to Evelyn’s room. I switched her phone on and went through the contacts list.
There he was – Ryan, her boyfriend. I had an idea.
I dialled his number. He instantly picked him, the needy bastard.
“Hey Evie, what’s up?”
“Hey Ryan”, I said in the most sultry voice I could muster, and followed that up with kissing sound.
“Whoa, someone’s in the mood today!”
“Oh yeah baby, you see I’m alone in the house. I’m feeling so lonely. Come here was fast as you can, okay?”
“Uh, all right, you sure you okay? You sound a little off?”
“Do you want to come or not?”
“Um, yeah! Sure!”
“Yeah, I’m waiting.”
Sigh. That felt weird. I giggled; this was going to be fun.
I looked at my hot body in the mirror and took off my clothes. This was the first time I was getting a full naked view of her body – it was so perfect. Her tits were not only large but tight – they stood out proudly. Her tummy was smooth and flat. I let o0ut a little laugh on seeing her shaved pussy.
I opened her cupboard, rummaged through her clothes and finally found what I was looking for.
A pair of red lace underwear, and a little something I definitely did not expect to find – a sheer black negligee. I felt so turned on when I put them on. The smooth material felt to sexy against the smooth skin.
I felt my pussy growing moist. I touched it, it was sticky. This felt amazing.
I began putting on her blood red lipstick, and just then the doorbell rang.
Ryan was already here? Boy that was fast.
I adjusted my hair and walked down the staircase. I tried walking sexily, you know, swaying my hips and all.
Finally reached the door and opened it.
It wasn’t Ryan at all, but the milk man.
His eyes definitely popped when he saw me. And again, I had an idea.
“My my, Evelyn... well, you’ve certainly grown into a- umm...”
I giggled. “Why, thank you. So, what brings you here, sir?”
“Oh, well, here is today’s milk... and that’ll be the usual three dollars.”
“Oh, but sir, I don’t have the money to pay you.”
“Well that’s okay, pay me next time! I come here every few days’ right?”
“Oh no, that will not be acceptable, sir. That’s against my principles, my father always taught me to never have debts.”
Before he could say anything I brought him inside the house and led him by the hand to the sofa.
I sat right beside him.
“Now, could you think of some way how we could finish the deal? Cash, or kind...”
“Really, Evelyn, it’s not an issue. I can –“
“Sh.” I placed my finger on his lips. He was clearly feeling nervous. I looked earnestly into his eyes and said softly, “I have a good idea, actually. Why don’t you give us the milk today, and I –“, I swung my leg over his knees and sat on his lap, “ – give you the ride of your life, huh? How does that sound?”
Before he could say anything I sealed his lips over with mine. I pushed his head down with a deep, heavy kiss, literally sucking on his lips, and then broke the kiss abruptly.
He was gasping, but there was now a definite fire in his eyes.
“Whatever you say, baby!”
Before I could say anything, I picked me up and threw me on to the sofa on my fours. He quickly pulled my panties down and in an instant I felt a hot penis pumping my pussy front he back.
I was automatically moaning and my pussy was just getting wetter. Then I started pushing my hips back on to him and rolling them to match his pace. He was going at it pretty hard, calling me names in the process.
“You little slut, I’m going to bang you senseless.”
“Yes, daddy, give it to me! Oh fuck!!!”
“Yeah bitch, who’s your daddy now? Who’s your daddy now?!”
“You’re my daddy! You’re my daddy! Now make me your cum slut! Make me your little bitch! Oh! Oh god yes!!”
Before I knew it, I could feel my hips involuntarily bucking. I was nearing my orgasm! I arched my back and pushed my ass as further back as I could. He too sensed it – he increased his pace and force. And then, one two, three....
“OHH!! OH MY FUCKING GOD! DAMN IT YES MOTHER FUCKER!!” I went on with a long list of slangs as I came hard in my sister’s body, I realized that I had squirted out some fluid. Then, tired, I collapsed on to the bed.
Before I could take in what just happened, I felt the milk man grab me by the hair an lift my face up to his, “This was supposed to be for me, bitch, not for you!”
Then he threw me on tot he floor. As soon as I lifted my head I felt his cock jammed down my neck, and thereafter began a steady pounding of his dick down my throat. I loved this insulting of my sister’s body.
“Don’t just look at me, do something bitch!”
I immediately started fondling his balls and bobbing my head down his dick. After a minute or so, I felt his penis pulsating really hard, and before I knew it, it was spewing hot sperms into my mouth. I didn’t swallow it; I held it there as the milk man took his cock out. Looked up at his happy face and winked. Then I opened my mouth and let the warm liquid flow out of my mouth. It dripped down my chin and dirtied my negligee and the floor. The milk man couldn’t believe his eyes. I closed my lips and formed sperm-foam bubbles with my mouth.
“Go on, click a picture.”
He didn’t need to be told twice. He took out his cell and took a nice close-up of me licking my cum-stained lips.
Hardly was he done packing his cock back into his pants when I heard –
“Evelyn? What the fuck?”
We both looked at the open doorway. Ryan, dumfounded, was standing there with a bunch or roses and bottle of wine.
“Hi baby”, I wished him. Boy this was going to be more fun than I thought.
“What the hell are you doing? And... Is that the milk man?”
“Yeah.” I walked over to him and brought him inside, not even caring to lock the door.
“You’re done I suppose?” I asked the milk man.
“Yeah, I’ll probably get going.” He scampered outside in a hurry.
“Good. Now, Ryan, I’ve got a few things to tell – “
SLAP!!
I can’t believe he actually slapped me.
“YOU FUCKING SLUT!!! JUST BECAUSE YOU COULDN’T WAIT FOR ME TO COME HOME, YOU GOT YOURSELF SCREWED BY THE MILK GUY!! YOU’RE A WORTHLESS WHORE!! THAT’S WHAT YOU ARE!!!”
This day was just getting better and better.
“You’re right Ryan, I’m so sorry. But it’s just that, my pussy – “
“YOUR PUSSY WHAT?!? I DON’T GIVE A FUCK ABOUT YOUR PUSSY!! Wait, I’ve got an idea. This should put you right.”
He took out his phone. “Now listen, when I start shooting the video, you’re going to say, no, swear, that you’re my personal cum slut. You get it? You will also say that you want to be my cum dumpster. Not that you weren’t, but let’s make it official, shall we? And also say that you have an innate desire to fuck your dad, your brother, and your mom. Swear by it. After this, you try doing any funny business, and this video is on the internet. And I’m also taping our fuck session today. So start.”
He began shooting, not even waiting for a reply. I gulped. This would mean officially fucking up my sister’s life forever. Did I want that much?
Oh who cares, of course I do!
So I moved my hands through my hair and very coolly began saying everything he just told me.
“Hello, boys. My name is Evelyn Gardner, and I’m 21 years old. I’m completely in my senses and everything I’m about to say, I mean that for life. I swear to god. So, what do I start with? Yes, my official position in this world. Many of you want to be doctors, teachers, and lawyers, whatever! But I? I just want to be a useless cum slut. That’s right, I want to be a cum dumpster, forever. And there is only one man, who can officially own me, and that’s the guy who’s shooting this video, Ryan. I’m like his rag doll, every time he feels horny, I’m there to take his cum, irrespective of whether I want it or not. He practically owns me, and I love it! Moving on, I have to confess – I’ve always wanted to have sex with my family. My brother, my mom, my daddy, everyone! I just want sex. What can I do? I’m a sex addict, and proud! So, cheers to life! Bye bye guys!”
He then put the phone on top of the side table, from where everything I did was going to be recorded. I could see a wet patch on his trousers. I smiled.
But then he held me by my hair and yanked my head down to where he sat on the sofa. “Don’t get too happy bitch, your punishment’s just getting started. Now lie across my ass so we can get started.”
I did as I was told. I could feel his hands all over my back side. He was feeling my smooth back. Then he squeezed each ass cheek and kneaded them together. And then –
SPLAT!
He delivered a hard spank against my right cheek, causing me to shout out in pain. Then came the marathon of spanks, one after the other, in quick succession, hard, fast and swift. No matter how much I shrieked, he went on slapping my fat ass.
