In recent years, public opinion calling for "gender equality" and "diversity" has been gaining momentum... This is the world of 20XX, where these voices have grown so loud that "female superiority over male inferiority" has become the norm. Prisons are no exception, and unreasonable bullying is carried out in the name of education. There is nothing they can do about the unreasonable semen milking that takes place every day! The beautiful prison guards don't let up on their punishment! They don't let the men get away! "Produced and copyrighted by KM Produce Co., Ltd."
