How many of your friends do you think would fuck me?

We were laying in bed together after a long day and Jane suddenly asks me, "How many of your friends do you think would fuck me?"

I just laid there stunned for a second thinking I must have misheard her. I manage to stutter out "What?"

She casually replies back "I was just wondering if I decided to start cheating on you, how many of your friends do you think would fuck me?"

I think about how to reply thinking it would be better to play it safe "Probably all of them you're very hot and they know it." She seemed satisfied with that answer and drifted off to sleep and I hoped that was the end of it.

The next few days seem to be normal with no more mention of what was asked. She did seem to be on her phone more then normal though, she was always smiling and laughing but I didn't want to pry into who she was talking to. I noticed her taking some selfies which wasn't unusual but it was odd when she started taking her phone into the bathroom with her.
