How to ask her if she wants another cock in her pussy

[asudas1709]

I am my GF's third BF. Coming from traditional background, I could not speak to her openly about my wish to get her fucked by other men in front of me. She had regular sex with her previous BF and as well as me. However she thinks that I am conservative. However she sometimes tells that she loves to have male colleagues, she loves if someone stares at her cleavages through revealing dress. is she also hinting the same?
