You have 2 weeks, take thing slow. On the side note, you will be in japan, when sex is display publicly in the open. You will have a lot of chances to game her, make her aroused then you can get whatever you want. For example:
Love hotel: dont press on the sex issue, just act like you're curious and wanna check out. Make sure to build up rapport and kino before you take her there. Get to the room, and you know what you should do.
Take your time, you will have plenty of chances, isolate her from the group, build up good rapport and just enjoy your time with her.
