Not a throwaway, but possibly the only post I'll make. :-)

Hi guys never posted before but I've been seeing this very kinky girl (27) on & off. We both live in a foreign country and her (lesbian) twin sister  is visiting this week. They repeatedly had sex with each other when they were teenagers and my girl regularly confesses her threesome fantasies involving me. Never met or spoken with her sister before but she's very interested in me.   I have never done anything like that and now a window of opportunity is looming large. Tomorrow the three of us will be making a trip and staying for a night or two in a hotel. I have been out of the PUA scene for a while and am rusty. I would love any advice, pointers or quick guides on making this opportunity fantastic? And of course I will come back with a full report if successful. Thank you!
