<human>: Occasionally my girlfriend says that she would like to have a threesome with another girl so that I can experience have a blowjob from 2 girls at the same time. She's ok with that, but not with penetrative sex.

So what I did for fun was to look for girls near where I live in /r/gonewild and message them for a threesome (On my otherthrow away account). I got a reply from one cute girl, but how do I bring this up to my girlfriend?

I'm afraid that she will be pissed that I looked for another girl without her permission. What do I do? It's hard to find unicorns.

Provide a brief overview of the text.
<bot>: Gf said that she would find it hot to have a threesome with another girl. I found a female on /r/gonewild without her permission. What's next?
