my story is this:

I dated 2 girls, after the 1st date (different days) I added them on facebook

while browsing their pictures I found out that they are best friends and have many pictures huggin each other

I brought up this new information to one of the girls and she inmediately proposed to go to a nightclub with his friend

So my question is, what are my chances to make this a threesome in that single night im out with those girls

what exactly should be my best strategy, and most importantly how can I start turning the conversation into sexual things

I really need all your knowledge at this time, I want this to happen I would for sure try
