Over the years I have caused the slut sub (CuriousFern) to cry occasionally. This video is the first time in 12+ years she has screamed. The new zipper design (V2) worked perfectly at inflicting serious pain without permanent damage. Thanks again to sub cunt boy (BostSwitch) building these to my specifications. For some unknown reason CuriousFern has not thanked him for all the work he did...
