What's the red pill view on wing women?

So I have a new plate, sex and vibes are great. Banged her already 4+ times. It's clear that we are FWB, me and her brought up the topic multiple times. She is cool with that, and me too.

Once she also said that she would like to go out together and I can be her wingman and she would be my wingwoman.

We actually went to a party together on satuday and it was fun, I flirted with some chicks and took some numbers, she also flirted with some dudes.

In the end we end up dancing and making out together and went home together and had amazing sex lol.

​

Do you guys think it's a good idea to go out together again? I think it's good for social proof and it was also fun. It was also more fun that just going out with my chodes friends that just drink beer and don't approach. With her I can dance with her then pull in other chicks and go on..

I also told her that would be fun to have a threesome with another chick, but she wasn't super enthusiastic about. I'll have to work on that.

The only thing that I am worrying is that if this happens multiple times and she goes home with some dudes and I don't pull, that my value could go down. But maybe it's just mental masturbation because she likes sex with me and she already call me Sir while texting haha.
