Kira Sin is an American brunette performer who worked heavily in gonzo and anal-focused studio scenes during the 2010s. She appeared for Brazzers, Jules Jordan Video, Evil Angel, and other high-volume hardcore labels. The thing people remember is how calm she looks when a scene turns intense, then that quick smirk that says she is still completely in control of the mood.
