First, build the tension.
Wear a sexy dress, no bra. Excuse yourself to the ladies room, come back, and put your panties in his jacket pocket... Play with him under the table during dinner... In the car, play with yourself while he drives, or better, take a cab, and let him play with you, or you suck him, (but don't let him cum yet!) while you are in the back seat. Put his hand under your dress in the elevator... Undress yourself in the hall outside the room while he fumbles with the key... and when he gets the door open, kneel in the doorway, and suck him some more!

In the room, maybe something new?
Glynwr's suggestion of inviting a GF is good...
but if you want to keep it a private occasion, do something you have never done before. Dedoo's and Fang's ideas are good, or maybe offer yourself for anal sex, if is new for the two of you.
Later, after he has slept for a while, wake him by sucking him, letting him cum in your mouth before he is completely awake, or after he is hard, let him awaken while you are riding him...


Well now you know what I was doing New Year's Eve....




Wickedly,
