I'm in love with a girl who's straight. Anyone give me tips on how to seduce her?

First off I'm James friend on his account and I'm a girl. My bestfriend let's me cuddle her sometimes, and we hug alot aswell. We had a wrestling match a while back because we were high and I got to touch her quite a bit. I'm a lesbian and she dosnt know that. She's straight. I'm going away with her soon so how can I seduce her?
