Naked is cool, but what really turns me on is if she's wearing clothing a certain type of way.
For me, I like it when my women is wearing some nice looking shirt, I pull it over her breasts so they are showing, but it's still on. After 2-3 hours of constant pounding, I'll take the top fully off, and resume.
I also tell her to keep her pantyhose on, damn that's sexy. Something like this. (And obviously her panties are off)
I also like it if she wears some jewelry.
And high heels. My god! Ladies, you cannot go wrong with those.
You add all those things up, and you got a energizer bunny long lasting hard dick. I bust multiple times.
