Suck your sister's toes
From Create Your Own Story
"After everything I've been through today," you tell him, "sure, I'll suck her toes."
"Alright," your sister says, cockily sure that you're bluffing. "Let's do it right then. Crawl over here."
You crawl over to her on your hands and knees and she puts her foot on your head, pressing it down to the ground and stepping on the side of your face.
Requirements: This is a story about a young girl written in second person.
