Practice Eating Pussy With Your Sister

Big Sister is in her room, watching a video with her hand down her shorts. At first she's embarrassed, but eventually admits that she was watching a video of a naked girl. The girl's boyfriend was licking her - down there! It looked like a lot of fun, so Sister was just pretending that her fingers were a boy's tongue. Fingers don't really feel much like tongues, though. Would you like to help your Sister out and lend your own tongue? It will be great practice for when you get a girlfriend of your own...
