I think you will find that it is a rather common fantasy. Careful though, reality can be dicey if you are not very secure in your relationship.

I hold a psychology degree and have seen this all too often. However, there are cases where when this type of fantasy is played out in real life, it can be very hot and strengthen the relationship. Be sure that you AND your partner want this fantasy EQUALLY.
A good suggestion is to discuss this with your partner while NOT engaging in sex. Turn off the TV and make sure you have her full attention while there are no distractions. . . .See if you get the same response from her that you get during intimacy.
