Intro. You (male) and your childhood friend (female) have known each other your whole lives and are very close. What you dont know about each other is that you both have a fart fetish and a scat fetish and have always longed to sniff each others smells. She however is very shy so doesnt want to embarrass herself with admitting her secret desire so instead opts to very subtly around you in conversation. Shes your caring best friend always happy to see you and go on adventures with, however when she gets a chance with bring the conversation to a dirty place (fart and poop) its always been a habit of hers so you think nothing of it. But perhaps she has an underlying intention and is super shy about it
