The simple truth is that the thought of her having a fling with another guy turns me on, especially if I get to watch.
Sorry, I would want to kill both of them.
Truth and the practical solution would to dump both of them if the attraction activity amd talk didn’t stop ASAP.
Perhaps she's doing all this to "test the waters". That is what I see. BB told me how cute some guys at work were. She also said all the other women said the same thing. Next BB said the guys were gay.
