Let me just start off by saying that I've never really followed any routine stack. Was taught MM but soon developed a natural flow, using "infrastructure" of MM. Not so sure about the structure of Field reports either.
Field Report:
So this girl, jane (alias' are used), is my close female friend's (sash) sister. There as been some attraction between us over the past year and half but i never really acted on it due to unknown boundaries (which have now made been clear) with Sash. In fact, sash is all for me getting with this girl
I understand that this might be one-itits, in fact it probably is, but we've all met that one girl that is just sometimes worth forgetting about everything you know.
SO tonight we had a house party, nothing big, and there was obviously alcohol involved. Beer pong was played and we all got a bit tipsy. I teased jane by tickling her when she missed a shot and gave her some light banter about how i should show her how its done and that she should make a booking with my PA for a class, first one is free

. half way through the night we were chilling on the stairs and taking pictures (she initiated) which thinking about it now, i should've maybe transitioned into the Photograph routine? I told her that we should go upstairs and she said okay, but quickly went on her phone which was an obvious sign of hesitation. That moment walked on by.
We eventually were left alone on the roof under a really nice sky. i pulled her in while speaking to her, but for some reason i hit a block and didn't know what to say to get the close. she wasn't looking at me and would often put her head down assuming the "I'm too drunk" character. We went downstairs and i met up with my close friend Sash.
Sash knows i want to pull her sister so i asked her advice to which she replied "i don't even know my own sister anymore, she's very closed off with these sort of things". Jane came looking for me to which Sash saw the invitation to leave. we cuddled on the bed and she passed out, not completely, she still had the ability to hold brief conversations. i tried using the 5 questions game which usually works for me but she wasn't down for a game.
I eventually left her and told Sash that it isn't happening. She said try again next weekend because it might be because of all the people here.
Next weekend party (music fest actually) and me, Sash, Jane and another friend are going with the plans to all sleep at the same house.
Is there ay advice you guys can give me for my last try at this girl. after this last try I'm moving on (basically if i don't pull her sometime during that day, I'm searching for another girl to bring home that night.)
ALL constructive criticism is welcome, but please refrain from name calling and such.
