How to convince your girl friend to have a threesome with her best friend?

[Slim_Waka]

So i love my girl obviously. She's nice hot etc but the problem is her best friend who started flirting with me some time back and she's way hotter than mu gf. I definitely want to fuck my gf and her friend if possible at the same time so how do i pull that off?

Unless she's bi and wanting to explore sexual adventures, I highly doubt she'll fulfill your fantasy.

Huh, nice fantasy you got there. Pretty hard to apply if she's not bi.
