Voted other. As a guy it is sometimes not possible for me to see her eyes because I'm facing the wrong direction in a 69 position (We don't really do 69 because she doesn't like giving me oral, so I don't ask her to. But I LOVE going down on her!
) If I'm turned around the other way, unless her hips are on a pillow, I really can't get a good look at her eyes without getting a real kink in my neck.
That and her boobs tend to get in the way.
For the most part though, I LOVE to see her eyes, her face, her whole body as I pleasure her! It is a complete turn on!
