If you are fans of Japanese AV, you should know a series called Japnese sexy detective (潜入捜査官). The plot of the porn is that the female detective becomes undercover in order to investigate the bad things of the trial, but the girl usually got banged by groups unstoppably. This time Sara Oshino (忍野さら) acts as a hot female detective
This black tight detective costume is the label of this series. Someone might like this cloth very much. You can clearly see the busty body of Sara Oshino (忍野さら), and I personally think, that is much sexier than naked.
