Well.....

'd have to say ass/legs if they are on the mark everything else takes care of itself.

This question though begs the opposite in return as in: Which Body part can turn you off the most?

And for this I'd have to say gnarly hands and toes ( with apologies to Eddie Murphy) nothing can negate a perfect ass/ legs set more than cloven feet and grizzly hands are a non starter...as are bear trap teeth; but don't get me started on that  

Damn I guess I'm picky huh

I think I am normally pretty relaxed and composed in sessions, but there have been a few times where I have been stopped in my tracks.  And it is not one body part.  It is a couple of things going on at once.  But everything starts with "the look".  Usually after the warm-up chit chat where the eyes say "we are done pussy footing around, and I am coming after you now".  When that look is combined with a reveal down to a thong or something, I get totally amped up.  Some girls can say so much with their expression and eyes.  And if they know they have you rattled, they turn that dial up even louder.  That is what does it for me, and what I remember long after the session is over.

The glow of beautiful skin on the shoulder really whets my appetite.

Her Smile

A pretty smile melts my heart each time.

This one's easy for me...Bewbs!

And may I say Ms. Emy, that you have a spectacular pair!

Nothing is a turn off than skinny legs without any muscle tone. Nothing sexier than a pair of woman's legs with toned calves, hamstrings, quads, and glutes. I am not into female bodybuilders, but the stick-figure look is out.
