Date Night - wine at a local bar

I'm working on building up to a 3-some with my current LTR, who I see and hang out with for a few days a month. Sometimes it is in LA, and other times it is in the city she lives in

She is very comfortable sexually, and I have brought up the subject in the middle of sex, and we have role played / fantasized about threesomes. She told me that she has always been attracted to other women, but was shy about it, and that my comfort level has made her curious to explore that side of herself

Last night we went out for some wine at a bar a few blocks from her place. The place is packed and we sit at the bar, and have a good chat over a glass of wine. As the place is starting to quiet down, I start to play some games with her.

First we play Murder/Marry/Shag. This is actually in the routines manual, and goes something like this. First, you pick out 3 guys from the room, and she has to tell you which one she would murder, which she would marry, and which she would shag. And why. This is fun because you can pick out three total beta losers, but what I did was pick out two losers and one pretty attractive guy, to which she said, "Oh yeah, I would definitely shag him", haha

Then she picks out 3 girls for me to choose from, and we play with that a little bit.

When she picked the guy she would murder, she used words like "gross" and "disgusting" to describe him. He was actually with a pretty cute girl, and we read their body language. Her guess was they were on the 3rd date. She made a few comments about how the girl was really cute, and didn't understand why she was with the gross guy. I asked if the guy had gotten laid in the last 30 days, and she thought no. There were also 3 dorks over in the corner, and I asked it they had gotten laid in the last month. Definitely Not! Really?

Now the guy that she said she would shag, I asked which 3 girls in the bar would be most likely to go home with him tonight. She made her guesses, and I agreed with them.

Now, I asked her which 3 girls in the bar would be most likely to go home with HER. She said one of the waitresses, because she seemed naughty. And I suggested that the cute girl with the gross guy would actually be more likely. She was curious, so I explained that the gross guy was going to try to kiss the cute girl later, and she was probably concerned about that. At the same time, she had been flirting under the influence of alcohol for a few hours, so probably had an elevated buying temperature. She thought this made a lot of sense.

So now I suggested we test the cute girl and see if I'm right. "How do we do that?" I said we could make out heavily at the bar, with my back to the cute girl, and she could make eye contact with the cute girl while we did it. If the cute girl looked or watched, it would be possible to tell by the look in her eyes that she was interested or curious. And she did look. And my girl was really turned on by that.

The gross guy got up to go to the bathroom, so I suggested she run over and say hello to the cute girl and tell her that she found her attractive. She wanted to... but she had AA! haha. So she didn't approach, and I didn't either, but we went home and fucked like crazy while fantasizing that the cute girl was in bed with us.

We are planning on going out again tonight, so I'll have some opportunity to refine picking up the 3rd wheel for our tricycle of love
