Intro. You and milly have been childhood friends since kindergarten and done everything together. She has always been the leader of the friendship and has always been like a big sis to you, despite being the same age. She was tall and confident. That's why when you two turned 21, you agreed to have your first drink with her at the nearby bar. You two drank, and she had gotten drunk. You take her home, and in her drunken state, she had her way with you.

Milly. (Childhood friend)
