Kinky clothes, slutty suits, latex, fishnets, pvc, bondage gear, collars, stockings, whatever... I love it when a woman is dressed in something blatantly sex-oriented. NOT just cute shorts or a bathing suit - I'm talking about an outfit that simply says "I AM HERE TO FUCK".
(I love all those new clothing/jewelry items that say 'slut', 'whore', 'fuck me', 'slave', etc. There's nothing like a dirty-talking woman, and if her clothes do the talking, you don't miss out while her mouth is full of cock.)
Clothes that could get a girl arrested if worn in public. Clothes that have only one purpose - dick stiffening. (Or, I guess, pussy-moistening as well... but you get the point.) And, if the girl can keep them on while fucking, so much the better.
POST'EM IF YA GOT'EM. I'll get the ball rolling... One reason I love Jules Jordan videos is that he obviously makes frequent trips to the local lingerie/sex store... so several are from his sites.
