Tonight, my friend met up with some girl another friend had set him up with. She wanted him to come to her house, the only problem was that her two friends were with her, so he enlisted me to help him out so he's not ****blocked. He told me that her friends were Bi-sexual, and that one was really hot and the other was sort-of-not. So I decided, "what the hell, I'll take one for the team". I went with him to meet this girl (this is the second time he's seen her), and I met her two friends. One of them (the HB6) was trying to ****block my friend, telling him no PDA, and **** like that, but I was able to divert her attention. The other (HB9) was somewhat quiet, but she would whisper something to her friend every so often.
We stayed for about a half an hour then left. I just found out (from my friend), that HB9 thinks I'm "Super hot" and she's into me. I know for a fact she's Bi, because not only did I ask her point blank, but she was also making out with HB6 a few times.
They want (my friends girl, and HB9) to meet up again with me and my friend.
My question, how should I handle the Bi situation? Should I play it regular, and try to eventually work in a 3-some (if things go well)?
