My first time meeting my sister, the last time ever seeing her… a murder fantasy.

When I first met my sister, I was 22 years old and being introduced to a sibling I never knew existed. My dad had a daughter with another woman while my mother was taking care of me, while I was still just a newborn… my dad was not parent material, so he just up and left us both to have two more kids. But one day, I logged on to Facebook and saw a new message from a beautiful girl with auburn hair and green eyes:

“Hey, this might sound sort of strange, but I discovered you after I did an ancestry search. You’re my brother, our dad had me with my mom around ten months after you were born. I’d like to meet you, would you be available to get together?”

I looked through her pictures and was struck by how gorgeous she was. I knew I was attracted to her, but i had to get around that and be normal. That kind of urge is perverted but unavoidable when you don’t have that ‘brother-sister’ long term relationship. This girl was a stranger by all means.
When we met, we had coffee and a great conversation. She kept shooting me strange looks, and then would get a shade of shame over her face. I knew she felt attracted to me, too… when we left, I grabbed her hand and pulled close to kiss her. I couldn’t fucking resist it, it was like an unstoppable force. Our lips met, and she pushed forward to make out with me sensually. After a few seconds, she pulled back and said, “oh god, no, no… we can’t. This isn’t okay.” and I stepped forward and kissed her once more. She uncontrollably savored it again, and I said “do you feel that? That’s you wanting it. Its the most okay thing in the world, the spark we make together.”
She thought it through, and we decided to go back to my house to show her my guitar collection. When we got there, she says shyly, “I’m not going to do anything sexually. That’s too far. I hope we can just be uninvolved intimately.” I knew, however, that a fire was growing.
As soon as we got in and sat on the couch, she kept glancing toward my crotch. I sensed the chance and took it – I reached in my pants and pulled my cock out. It was already half-hard from the excitement in my mind. She gasped and acted shocked, but it quickly turned into raw, sexual energy. She grabbed it meekly and began to stroke it, moaning with anticipation. There was no stopping it now… she put her lips around the tip of my dick and pulled away, looking uncertain. I helped her realize which way this situation should go by delicately pushing the back of her head until her lips were above the head of my cock. She immediately took it down her throat with surprising aggression and vigor, pushing her lips all the way down to the base of my member and expelling a pleasured gag noise once she’d slid all the way down to my balls.

Then it all went downhill – she had a sudden change of heart and pulled away again. She had tears welling on the sides of her eyes, and I knew there was no recovering from this. She said, “I can’t believe this.. we can never do this, this was a huge mistake and we shouldn’t ever talk about it again. This never happened, okay?” not okay. I was already fully turned on and dying to be inside her. I swiftly grabbed her arms and sat her down. She struggled and squirmed, yelling loudly and sharply in a way that was aggravating to me, I was hit by a enraging wave.

“No, oh my GOD, don’t! Don’t! Please, fuck… PLEASE!!!” Her words were just noise to me now, an unconcerning shrieking sound. I tore her shirt off of her using my pocket knife, and when she saw the blade in my hand, she began to be more compliant and docile. You should never squirm and thrash around when you’re near an open blade that’s as sharp as a razor. Despite being terrified and paralyzed with fear, her nipples were as hard as diamonds from the adrenaline and fear. I licked the tips of her nips – they were as sweet as honey. Then, I finally began to slide her shorts down to her ankles, tossing them aside… I used my knife to cut her panties off, making sure to slide the back of the cold blade against her pussy; she whimpered quietly and shuddered. Was the shudder one of pleasure or fear? I didn’t really give a fuck.
I rubbed her pink, glistening lips and forced my fingers inside of her warm slit. She began to cry loudly and thrash around again, causing me to struggle with keeping her down – so I forced her on her stomach, wrapped a cellphone charger cable around her throat, and pushed my foot down on her back; causing the cable to tighten fully – she had absolutely no way of getting free.

It seemed like forever until she stopped convulsing and twitching, like I would be stuck strangling her for eternity. But after nearly six minutes, she finally collapsed into a pile of asphyxiated, naked ass… sure, she was dead now, but the pussy was still fresh and still just as fucking beautiful. I shoved my cock all the way down her throat, pumping it so far down her neck that her delicate swan-neck was being stretched, almost comically, to nearly twice its width. I cut myself off before cumming; I had special plans for my load.
You might have approached the perfect pussy popping out at you, but that wasn’t the road I planned to walk. I took my rock-hard dick and plunged it into her tiny asshole, and I knew right away… I was the first guy to ever anal fuck her. I lubed up with some of her overflowing pussy juice, and penetrated her asshole as deep as possible, poking her guts with no regard or remorse. Finally, I pulled out and shoved it down her wide-open gaping mouth, bursting a load so potent and powerful that I wavered in the legs, almost falling over from the waves of euphoria. What a crazy fucking day.
