Normally this is the easiest one itis to turn.
Because you already know her and she already knows you, that whole second day shit is irrelevant. Just for inspiration this is what I did the last time I had a one itis friend I wanted to turn:
ESCALATE!
It's pretty simple. Don't tell her you love her, don't say you want more and don't let her know how you feel. Instead, kiss her.
What you could do would be to call her, small talk with her and invite her over for a movie at your place. When your talking on the phone, mention how you earlier that day bought some scented candles you just couldn't resist picking up, and that she totally should check them out when she comes over.
When you pick a movie, something like "Just Friends" with Ryan Reynolds could scare her of, because of the message of the movie, where as "The Brave One" with Jodie Foster might give a better impact on her. You should be the judge as to what works better. Anyway so you invite her over, you already have candles in place and because you told her, on the phone that you bought them for yourself, she won't feel intimidated.
Make sure you the room you're watching the movie in isn't very brightly lit. You are going to need her pupils to dilate for later on. And make sure you light the candles before she comes in so it doesn't seem like "Oh I've been waiting for you, before I could light the candles" unless she asks you on the phone.
All right so movie time is on, and during the movie, you laugh with her and you cry with her. If there's a surprise element in the movie, you are going to want to take her hand. Yeah - cause its okay to escalate!
Go kino during the movie not too much but do it!
After the movie, sit down and create a deep conversation, with stuff you haven't already asked. Could be "What is your biggest fear", "How do you see yourself in 10 years", "If you had one chance to go back and change something from the past, what would it be".. You know that kind of questions.
When she feels like she is able to tell you anything, start with questions like "On your entire body, what's your favorite place to be kissed?". You know and escalate with the Q&A's. Questions like these turn her on. So start giving her a massage, and make sure you finish by her butt, and give her the single greatest butt massage ever! When you are down there, start rubbing the outside of her vagina.
And now she might let you do this for 1 second or maybe even 6 seconds but then she will tell you to stop. Because this is all of the sudden an area she did not expect from you. But to calm her down and continue o turn her on whisper stuff like "Oh that thing you said about..... Just totally turned me on", and put in whatever hot stuff she spoke about earlier. Kiss her, undress her, fuck her and hold her when your done.
Side note: When you have a one itis you are about to fuck. Stimulate her clit, and then move to the g-spot for 10-15 minutes. When you start banging a one itis it will go fast. Like really fast ejaculation from your side and you are going to want to leave her satisfied as well.
Good luck!
