There isn't one thing I like in specific.
I noticed that her face must be nice. If she doesn't have a nice face I'm blinded to the rest. I like all kinds of features: thin lips, big lips; french nose, roman nose, hooked; big eyes, asian eyes... it's in the harmony of the face. If the face is harmonious, I like it. Eyes are the draw, in general.
Now, for the bod, I really don't like when they pass a certain threshold. Skinny is much better for me. Toned and muscular is on another level. Plump can be gorgeous, but it really shouldn't look like fat. Then I lose all interest.
I like flat chests a lot. I wouldn't say I like them more than big breasts, it's just a different flavor. The ass must have some amount of chonk.
Like them tall and short, but I have a thing for shorties. Blonde or brunette doesn't matter. I love women from all races, there are hot ones everywhere.
I love feet. I wouldn't call myself a fetishist, because I do get off to other things, so it's more of a kink. If she has nice feet, and she always shows them, it's fucking great. I like stilettos, nylons, garter belts, lingerie, nail poilsh, fishnets, knee socks... all things having to do with female fashion actually. I love the undress part, when the dress is good. To me a porn video could be slow undress and then straight to throat fucking, or sex with visible toes and soles.
