Your hot, plump step-sister, Sydney Screams, is getting ready for a date and they asked you to grab their water bottle. The scene starts as you hand Sydney the water bottle, and as you're starting to leave the room, Sydney stops you and asks if you'll help them pick out an outfit to wear. Sydney has been chatting with a really hot guy on one of the dating apps and is so nervous about meeting him. You stay and help Sydney pick out an outfit, hoping that they'll keep having some of the water. As you help choose the right dress for Sydney to wear for their date, you also want to see what they're going to wear underneath. Once you've convinced Sydney it's ok to try on lingerie in front of you, you're getting desperate. When will Sydney have enough of the magic potion you slipped into their water? Then it happens. They take a huge gulp of the potion and it starts happening. Sydney goes cross-eyed as their body starts to spasm as you transfer into your step-sister's voluptuous body. Finally!! Your hands start exploring your new body, running all over your big tits, soft belly and thick thighs. Who knew it could feel this good?! You're not about to ruin your step-sister's date, so you text their date to let him know you're running a little late. You want to be prepared for when you slut out your step-sister's body to their date! You've never done this before, and if you don't know what it feels like, he might figure out something is wrong. First, you find a dildo and lube, then as you go looking again, you find a magic wand vibrator. You lean back and slide the dildo into your pussy, experiencing the sensation of penetration for the first time, then press the vibrator to your clit. As you play with your step-sister's body, you know tonight is going to get wild and sexy!
