Go have fun with your older sister, Kim

You had enough fun playing with your mother, so you decided to go mess with your older sister, Kim, instead. After turning into goo, you leave your room and you flow towards Kim's room and you see her by her window, having a cup of coffee.

She doesn't notice you as you slither on her floor, witnessing her beauty. She was wearing a gray robe, covering her supple D-cups and her huge ass. You also noticed that she wasn't wearing anything under her robe, which makes entering her easy. Her blonde hair was frizzy, making it seem like she just woke up. And judging by her cup of coffee, she actually just woke up. Even so, she still looks stunning. Your sister truly is gifted in the looks department and you can definitely see how much she inherited from your mother.

You cannot wait to get inside her body. Question is, how will you enter her?
