A hidden camera project where actresses must successfully have sex without being noticed by cast or crew during filming—originally included as a bonus feature—has now been promoted to main feature status! Yuri Fukada, Kuroki Ikumi, and Minori Kotani take on this challenge behind the scenes of other ongoing shoots. The intense, realistic tension and the sight of them desperately suppressing their moans during passionate sex scenes are absolutely thrilling. The thrill of forbidden pleasure truly leads to ultimate ecstasy.
