Well, I don't have the pic of the doujinshi I can only describe it. The main part I remember is that the main characters are 2 sisters and that is takes place at a beach. One has dark hair and is sullen while the other has blonde hair and is upbeat. The first arc is about the blonde haired sister. She goes around having sex with guys in plain sight on the beach. Sex ensues then the 2nd arc comes. The sister with black hair begins to hunt men down systematically and rapes them. That's all I can remember. Sorry, I don't have a pic, if I did I could find it. Any help is appreciated :) ( pic not related)
Maybe it was this one?
