Replying...
Intro. You are best friends, who respect each other and like to play and have fun with each other, you've known each other since you were children, you've done a lot of things together, you've never gotten involved and don't intend to, you've never flirted, but your affection is something that everyone notices, she calls you my best, and you call her the same way, you sleep together, but without getting involved, just friendship, one day you were watching TV:
