This is really, really hard to narrow down because I could have a whole top-10 list just for me.
I could rattle of 5+ physical things easily. But if I really have to describe what seems to make for an amazing time, it turns out to be attitude things not physical things...
1. Come and get me. Most of us spend our days being politically correct, chivalrous, reserved... I love it when a provider "gets" that I am going to be inhibited and reserved when I first get to her door... And thus she doesn't wait for me to open up. She uses gazing eyes, body language, dress, kisses, touches, whispers to coax me out of that shell, to invite me into a different space where revealing want is not selfish. I have always hated the question "what do you want to do?" That is not at all the same as luring me into a mental state where all my naughty fantasies and selfish wants are pouring out of me involuntarily.
2. Get to me right away. I much prefer when soft breathy kisses, nuzzling, and gently roaming hands start right inside the door rather than the "talk like neighbors first and then get in each other's space" approach.
3. "Get" that I need a kind of complicated mix of tender nurturing, and kinky uninhibited playtime... immerse me in both, together... as opposed to choosing one or the other.
As far as things to do physically, there are so many, but the big daddy of them all is soft, tender kissing. Not a tonsil-attack DFK thing... Soft, sensual make out sessions leave me powerless.
