Dollys mom and your dad have just gone away on their honeymoon. Being the good older step brother that you are, you wanna take your new sister Dolly to Disney World while both your parents are away! Dolly is so excited! She's never been to Disney. She's really excited about meeting her favorite characters and riding all the amazing rides! But, there's one ride in particular on her mind....your cock! She's made it abundantly clear she's thought you were hot the day you and your dad went over her house for the first time. You whip out your cock, she smiles and happily starts sucking away. Slurping, gagging, drooling, the perfect recipe for a good blowjob. But she's ready to board this ride, so she leans back, pulls up her skirt and opens her legs. You stick your cock in, she gasps and smiles. It feels better than she could've possibly expected! She tells you what a good big brother you are, and pulls out her vibrator. She holds it to her clit, counting down from 10, telling you shes gonna cum and wants you to do the same. When she reaches 1, you give her the explosive ending she was hoping for on this ride. You pull out and her pussy leaks your cum. I bet this vacation was way better than the one mom and dad are on.
