Looking for a scene similar to this (read desc)

It's not the picture I'm looking for, it's a similar scene from a movie that has a sweaty brunette/redhead riding on this guy in bed, the guy grabs the telephone next to him but it slips out of his hand so he grabs the sheets. Afterwards the girl gets dressed (she either had her hair up or shortish) on the end of the bed saying she has to go to work. I think her dress had like a flower pattern on it and she had the guy button it in the back.
