My husband and I always play together and while I really enjoy being involved in the action, I also like to take a momentary pause during play to watch because I can see my husband's enjoyment from a perspective that I don't normally get to see. To sit opposite him on the bed while he's getting a blow job from a lady friend and I masturbate to his excitement is hot to me. Plus we get to make that eye connection at a distance which gets me real excited.
I have to confess, though, I wasn't always good with watching. In my earlier years, I wasn't totally comfortable not always being involved, but I grew and changed from my experiences and now watching is pretty cool.
