Your girlfriend Lauren looks at you and smiles.
”What is going through that beautiful head of yours’s babe?” As the tingling feeling goes on
”I think you'll like this hun!”
You feel yourself getting smaller and you’re now eye level with Lauren. Your black hair becomes softer and grows to the same elbow length as Lauren's hair before turning blonde. You smile getting a good idea of your wants. Lauren has always wanted a sister and has always called you ”sis” jokingly in the past considering how close you two are. It seems she’s really combining her fantasies with you. You feel her breasts form on your chest and her fit athletic body follows suit. Your clothes morph into a cute pair of yoga pants and tank top. Soon you are your girlfriend’s identical twin sister. But one thing you didn't expect was that you would be getting new memories added to your mind, you now have memories of growing up. You remember everything from starting pre-k to college together, all the good days and even fights, all of this strengthening your new bond. You have to take a seat on your girlfriend's bed. Your girlfriend was going on all in on the reality alteration as a new life was being crafted for you and her, you notice that two student ID badge's for Ralphersen University are forming on the desk, your mind filling with more information, you are no longer a sophomore in high school now you're a 22-year-old senior computer science major at Ralphersen University and your sister Lauren is going there getting an accounting degree. Your girlfriend's room starts to expand a bit, a new bed and desk form in the room, most of the ornaments from your past life show up on the desk and even some of your old posters appear on the walls. You still have memories of your past life but you feel more comfortable with your new identify as Laura Mathers.
Lauren now your sister looks at you, she hugs you, and then she starts to cry. You comfort her and begin to talk.
"Is everything okay babe?"
"Laura, oh god, I feel so happy!"
"You're happy!, oh okay, I thought you were getting sad."
"Oh no Laura, this feels so perfect!, As you knew back when you were my boyfriend, I have always wanted a twin sister, and when I met you for the first time all the way back in elementary school, I felt so many forms of love for you, it felt like our souls were much more than lovers, it felt like you were supposed to be in the womb with me but somehow you were born in another person, with this Chronivac, I could combine my desires with my love. You're my lover and soulmate, now in the body of the twin sister I have always wanted. I know this a new step for you, but I promise we will enjoy being sisters and lovers."
"Wow Lauren, I never knew you felt like this, I have no problem with this, but how will other people react to us? Like your.... sorry our mom and dad for example?"
"Don't worry about that Laura, I set up a feature to where people aren't disgusted by our incest, in fact they look at our love as pure."
"Wow you really do think of everything sis!" As you kiss Lauren and look into those beautiful green eyes which you now share with her. You two begin to make out on Lauren's bed and feel up each others identical bodies. Your love for Lauren reached new levels as you two have been close sisters and lovers, and when she kisses your neck you moan. You also love the new sensations of your body, Lauren is a beautiful woman and now that you have a body identical to hers is turning you on. You take off her sports bra before taking one of those magnificent breasts in your mouth. You swirl your tongue around the nipple and tease her a bit before doing so to her other breast. She then takes off your top and bra doing the same to you. She then rips of your yoga pants and slaps that firm ass of yours making you moan
"You like when I spank your ass sis!" Lauren says with a commanding tone as you moan in pleasure during your spanking and then you take off her shorts before sticking your fingers in her asshole. You then make her lick your fingers calling her a dirty whore for licking her sister's fingers after being butt fucked. She then eats your pussy out and this makes you cry tears of joy as you reach a very powerful and emotional orgasm. You then finger Lauren's pussy and you two lick the fluids off your fingers in the after glow of the most beautiful sex you two have ever had so far. As you two cuddle, you feel excited for your new life as you are now your girlfriend's identical twin sister.
