Alyssa ReeceStepsister Turns U Into a Girl

You and your step sister Alyssa had a fight at school because she was making fun of you in front of her cheerleader friends and you blurted out that she was adopted and wasnt really even your sister. It seems that your sister was a late bloomer and until this year she was unpopular and you would tell people at school that the two of you werent related. You had lots of friends and always teased her mercilessly.Then overnight she grew boobs and was hot and became head cheerleader. It was like the tables had turned and all of a sudden you were the unpopular sibling. Later at home she comes into your bedroom and surprisingly doesnt seem angry anymore."We should talk about about what happened at school," she says. You start to tell her that youre sorry and you shouldnt have done that but she cuts you off, "Its not a bid deal, I knew I was adopted." Youre confused but before you have a chance to respond says that there is something YOU dont know. She tells you that she has magical powers and that she is going to make you her sissy slut! You start to think that your sister has really lost it, "yeah ok, whatever sis," you start to say but then you stop because your voice has gotten a full octave higher. You look helplessly at Alyssa as your hands reach down to feel your breasts grow! "Do you like your new boobs?" Alyssa teases. "Theyre so perky and firm just like mine!" she laughs. "What the fuck are you doing to me?" you ask in your girly new voice. " I already explained it. When I turned eighteen I got magical powers, as my birthright. Now Im going to get back at you for all of the bad things you have done to me". "Look at how long your hair is getting!" Your waist is shrinking under your hands just as quickly as your hips widen."I know youve always been jealous of my curvy body." Alyssa says with a devious smile. Your legs are smooth and hairless and so long. "Why dont you look down your pants? Your dick is gone! Now you have a tight little pussy instead!" your sister says with a big smile. You gasp in horror as you reach down and come up empty handed. "Isnt this great? Im going to tell everyone at school that youre my cousin from out of town. The good news is that now you get to wear womens underwear and you dont have to hide it. Oh you didnt think I knew that you borrowed my bras and panties on a weekly basis?" You cant believe your ears. How did she know? You have been trying on her bras and panties for years. Womens panties are just so much more comfortable.And it turned you on to try on your sisters underwear because as much as you didnt want to admit it to yourself, you fantasized about her all the time. "Im also going to make you suck cock, and not just anyones cock. Im going to make you suck my boyfriends cock" Alyssa laughs again. "I know you hate him, but youre going to love his thick cock. As soon as you feel him in your mouth youre going to BEG him to fuck your virgin pussy! This is going to be so much fun isnt it?" she says with a big grin.
