....I am very tall so I myself tend to stare pensively ahead (and aside, as in, without eye contact) with a slight smile, while in full-time open embrace......
The thing that I have been wondering about is how do you maintain your concentration within the embrace you have with your follower. I would have thought that in open embrace especially your eyes should be concentrating on your partner's body postion and its alignment to you, subject to keeping a check of the floor.
