Knowing you like I do, I suspect she has a great sense of humor. Try tying her up and blindfolding her, and pretend you're bringing a sheep into the bedroom. Hoof steps, muffled bleating, maybe some leash noise. Nobody says it has to be serious and intense the whole time, and it'd be a great way to cut the initial tension.

When you're ready to get serious, tease the holy hell out of her before finally bringing her to orgasm. Not knowing what's next will force her imagination into overdrive, so mix things up from your usual pattern of behavior. Unusual angles of attention will also keep her guessing. When you're finally ready to let her go to completion, settle into a postion she'll recognize as one she regularly orgasms in. You'll be rewarded with a great sigh of satisfaction as she figures out the time to climax is finally nearing. Just don't make the barnyard noises near the end. Hell hath no fury....
