The situation is the following: I already built up a decent rapport and trust with a slightly insecure, HB8 - the best friend of my gf. I know. She is curious and my gf would try a threesome with her too. However, I might have screwed my game up a little bit (oh, the comments are coming): I sent her a love song on FB. Couldn't resist, for one; the whole situation is hot as hell, secondly I developed very strong feelings towards this girl for some reasons, that I couldn't control. In a weak moment I sent her Tom Odell's "Can't pretend", which has a very obvious message. Brilliant song BTW.
This is the chance to realise the big dream of having intimate relationship with two girls at the same time, and I would like to take it. I am aware that I handled the situation as an AFC, but there must be a solution, a great come back that would put me back in the game.
Please, any help would be very appreciated.
