Okay so here are some things I know about the story:

Its Bella/Edward but Bella is either dating or is married to Jacob

It's Jacob's fantasy to see Bella have sex with another man.

They go to the escort and pick Edward thinking he actually works there, but it was a dare from his friend or cousin and Edward got away with it because his friend's/cousin's dad owns the place.

During the sex Edward tells her that Jacob will never be as good in bed as him, and they have rough sex.

After they get done Jacob goes into the lobby, Bella walks into the lobby and sees Jacob flirting with the receptionist.

That's all I remember.
