Mary picks up the narrator at a party where he's been smoking pot so he's a little fuzzy. They go back to his place and start with the foreplay. The narrator is afraid he won't be able to "perform" until Mary goes down on him. Then they end up going at it on the floor or sofa because they don't make it to the bed. While they're going at it she tells him how old she is, but she's really hot so he keeps going.
Ok this is just my view.
