Incest: A Sexy and Satisfying Mistake

    My little sister Dani could be so annoying. As a twelve year old, all she ever seemed to do was hog the bathroom and asked me for rides. I set to working on a magic spell that would makes things different. After a week I had finished a spell that I thought would do the trick, one that would make Dani more "chill", even though I was still a novice when it came to designing spells. When Dani came into my room to ask me to take her to the movies to see a boy, I poured the potion containing the spell all over her. "What the hell!" screamed Dani, then the magic started to penetrate her body and she began to transform. "Da....Fuuuu" was all she could muster as her little pre-pubescent body started develop at break-neck pace. 

Her little bee stings soon become big, heavy porn-star knockers and all she could do to cover them was cupping the funbags with her petite little hands. Her hips flared out into a curvalicous midsection that finished with an ass perfect for twerking. Her hair lengthened and her face changed into the face of a perfect little cheerleader. 

    When the changes stopped and a busty, almost naked women was now occupying the time and space that my little sister had occupied not more than three minutes ago, we were both a little stunned and did not know what to do next. "I almost want to slap you," said Dani, looking puzzled "But all I really want to do is dance for you." She began seductively rubbing her breasts together and dropping to the floor, spreading her legs like a drunk stripper. What did my spell do to her? Before I could answer that question for myself, Dani took my left hand and placed it on one of her suckable breasts, and took my right hand and guided it into her pussy. I wanted to stop her before things got out of hand, but feeling her fertile, curvaceous body from inside and out, I knew what we both needed. As I tossed her onto my bed, Dani giggled like the little girl she once was. Before I could get all my clothes off, Dani grabbed my dick and drove it right into her open pussy. She wrapped her arms around me as she took charge and rode my cock, making sure I was hitting all of her most sensitive spots. My hands were getting big handfuls of her fat asscheeks. Her lust for me was so voracious that she must have orgasmed twice before I was even halfway there myself. She moaned for more of my cock. She couldn't take it anymore, flipping herself around and letting me pound her sweet body from behind. I was on the metaphorical mountaintop as I busted a perfect nut right into my sister. All she could say was "Yes, yes, yes," as she felt all of my semen fill her up. Her tits wobbled with excitement as she savored every last thrust from my monstrous dong. Her body was now my perfect fucktoy. After getting off of me, she eagerly grabbed my dick and practically tried milking it for every last drop of cum. Apparently, my spell to make my sister more "chill" had worked.
