So I REALLY lucked out last night and I ended up going back to these Finnish girls' place. They'd already mentioned a threesome a few times by this point (At first in secret to eachother, but there's no Finnish word for gangbang so I put the pieces together). When we got there, not a lot happened. We all made out for a bit but then one of them went home (This is the one that I was running game on all night, the other one just sort of latched on to us) and then nothing happened between me and the other girl besides a little more making out.

I have one of their numbers and am planning to call her up tonight. I really want that threesome to happen but I'm not sure if the window may have closed.

Any advice on how to steer this to my advantage?
