In an LTR with this chick right now who's bi. We fuck a lot (3+x per day, at least 5x per week). She's mentioned her fantasies about a girl fucking her, and always talks about how hot random girls are.

I've playfully brought up we should do a threesome, and she says 'lmao yeah with a guy'. I said not into that, and she said 'I hate guys like you, such a double standard. Just because I'm bi doesn't mean I want a threesome'.

Is there any way I can get her hamster spinning and leverage a threesome? I was thinking of sliding in dirty talk about another chick fucking her during sex. Thoughts?
