Hit Nana Plaza.
Enjoy some drinks and the company of sexy bar girls. Hold your ground and dont be afraid to choose your drinking partners. Its hard initially but easy once you get the hang of it.
Keep moving till you find a bar girl you really like (cock check to be sure no surprises).
Once you find your girl keep searching for a 2nd girl.
Once you have 2 girls negotiate a deal for both of them and ensure they offer lesbian service. Forget their asking price, demand what you want. If they dont agree move on.
Once you spend 3 to 4 hours shopping for girls take them both back to your hotel and enjoy.
Tell them theres a nice bonus in the morning for a great night in the bedroom.
Its that easy.
Just be prepared to reject politely women youre not keen on.
I do it all the time.
