Swap with Diana

You want to go to the party, but not as yourself! You put your things into the guestroom you go into Diana's room. It was nothing new to you since you've already been in here a couple of times. You quickly make you way to her wardrobe. Since she doesn't have any glasses you need to figure out how to transform your head. You find a hair tie of hers. Standing in front of the mirror you try to get the hair tie around some of your short hair. You already want to stop as you notice that your hair transformed a bit. It got a bit longer, allowing you to put the hair tie around it. Then you watch your hair growing even longer while it changes it colour to a dark brown. After that you see your face changing, looking more and more like Diana. You look into the mirror to see that you now have Diana's head on your body. 'That looks fucking weird' you think, so you quickly go to her wardrobe and take out some of her clothes. You decide yourself on a pair of normal black panties and a matching bra, then you had some normal socks, a thight sports top with long sleeves and a black, thight pair of leggins you often saw her wear. She already wore this combination of clothes to school a couple of times and you've jacked off to them a lot. Even seeing these clothes and her underwear laying in front of you gave you a huge boner. You quickly strip out of your clothes and begin to put on Diana's bra and her top. You feel your upper body slowly shrink as your muscles turn into Diana's beautiful C-cup breast. You also feel your arms shrink and raise your hands to see that they transformed into Diana's petite ones. After that you quickly pull her panties and her thight leggins over your already hurting boner. You suddenly feel how your boner starts to shrink until it even turns inside, becoming Diana's thight pussy. You can feel that she was way thighter than Beth was. After that you see how your legs loose mass which goes up to your butt. Your legs stay sporty but they are way thinner and you loose some height, while your butt transformed into Diana's big, sporty ass. You and many other boys dreamed of this perfect peace of meat, which was now yours. To end the transformation you put on her socks, giving you her feet and with that all her memories and characteristics. You find out that Diana is still a virgin, although she already gave a couple of blowjobs, was eaten out a few times. She also rubbed her raw pussy over someone's dick once, but it didn't penetrate her. So Diana's virginity was yours to loose now. You decide to remove the hair tie again since Diana always had open hair.

Before leaving you look into the mirror one more time. Looking back was one of the hottest girls in your class, completely under your control. You pose a bit in front of the mirror, marvelling at Diana's sexy ass and her nice tits, before going down to your original body. On your way down, Chelsea stops you. You can't help yourself but look at her huge curves, although she had one of the most beautiful faces too. The thought that this goddess was now your sister made you even wetter than you already were. You try to focus as Chelsea tells you that she will stay at Jacob's tonight. Meaning that you would have the whole house to yourself because Diana's mum, with whom the two sister's lived alone, was out till sunday evening. As she leaves you can't help but stare at Chelsea's huge ass. Your body was on fire, you just couldn't help it. The only question is what to do now. You could try to get yourself together and just go to the party with John. Or you could tell him you need to do something and head to the party later, allowing you to explore your new body some more. Or you could tease John and let him take Diana's/your virginity before going to the party.
