You try and make up with her.

You knock on the door, and say the following, hoping she falls for the "sensitive" act.

"Mary, I'm sorry I came early... I just couldn't help myself!  You're too damn hot to resist!  One look at that hot face of yours sucking my dick and it was all over.  I mean hell, you're so hot I'm already hard again!  Look, if you want to let me back in, I can make it up to you."

You hear her move on the other side of the door.
