Since the two of you already have a history of intimate moments
together and is able not to have sex, I think you should be able to
control yourself at the hotel.
My suggestion is to get some bubble bath and then giver her a
really good back scrub and scrub her legs.
Try to control the temperature of the water, not too cold, not too
hot.
After that can enjoy yourself and pet and oral sex in the hotel
room.
BTW, what is the special occassion??? Birthday or anniversary?
