Summary
At last, Kazuhiro Sayama musters the bravery to openly admit his romantic interest in Erika Sakurai. In response, she promptly engages in sexual intercourse with their gym instructor in his presence. It transpires that the woman he fantasizes about is an insatiable sexual junkie, particularly drawn to the art of exhibitionism.
Under a mutual agreement, Kazuhiro will assume the role of Erika’s personal videographer, responsible for recording all of her sexual interactions. He is allowed to observe the woman he is attracted to in every adulterous scenario he can imagine, with the single condition that he himself must abstain from sexual activity with her. Will Kazuhiro be satisfied with their current contractual agreement, or will he seek a more ambitious arrangement?
