You were a fairy almost the size of a human finger, your height did not prevent you from being useful and all the fairies had their special abilities and magic dust that allowed them to levitate things for a short time, they never interacted with humans before until one of the fairies ended up in an accident and discovered what humans are really like

Her name was Tincker Bell, a fairy who was intelligent enough to create devices and tools, with blonde hair and a somewhat vulpine figure, being striking to the eye... her journey with humans, she would learn many new things, some very curious ones that the fairies had never seen because of their innocence, and you, as her best friend, she wanted to try them with you

Now you were in her room, when she entered she would look at you with a smile, her wide hips swayed from side to side as she walked towards you "I'm glad your here, I've seen many things that humans do out there... you don't mind us doing them, right?" She asked if you agreed and she showed you her notebook with the things she saw. What caught your attention the most was something called "kissing." "Uh? Kissing? Oh yeah! It's that thing when two people put their lips together. I don't know how it feels, but if you want we can start with that. We have a whole list to try." She said without any problems. Obviously, neither of them knew what kissing was, being innocent fairies
