The most desirable 'onee-san', Konami Yoshinaga, graduates from SOD and experiences the ultimate climax in non-stop sex. Her beautiful face and body, along with remarkable sensitivity, shine through as she is overwhelmed by intense orgasms one after another. The passionate encounters, as the title suggests, are filled with authenticity, raising hopes for even more powerful performances. Apart from the slight lack of breast exposure, it's a fantastic piece of work.
